Background: Despite the development of evidence-based pneumonia guidelines, limited data exist on the most effective means to implement guideline recommendations into clinical practice.Objective: To compare the effectiveness and safety of 3 guideline implementation strategies.Design: Cluster-randomized, controlled trial.Setting: 32 emergency departments in Pennsylvania and Connecticut.Patients: 3219 patients with a clinical and radiographic diagnosis of pneumonia.Interventions: The authors implemented a project-developed guideline for the initial site of treatment based on the Pneumonia Severity Index and performance of evidence-based processes of care at the emergency department level. Guideline implementation strategies were defined as low (n = 8), moderate (n = 12), and high intensity (n = 12).Measurements: Effectiveness outcomes were the rate at which low-risk patients were treated on an outpatient basis and the performance of recommended processes of care. Safety outcomes included death, subsequent hospitalization for outpatients, and medical complications for inpatients.Results: More low-risk patients (n = 1901) were treated as outpatients in the moderate-intensity and high-intensity groups than in the low-intensity group (high-intensity group, 61.9%; moderate-intensity group, 61.0%; low-intensity group, 37.5%; P = 0.004). More outpatients (n = 1125) in the high-intensity group received all 4 recommended processes of care (high-intensity group, 60.9%; moderate-intensity group, 28.3%; low-intensity group, 25.3%; P < 0.001); more inpatients (n = 2076) in the high-intensity group received all 4 recommended processes of care (high-intensity group, 44.3%; moderate-intensity group, 30.1%; low-intensity group, 23.0%; P < 0.001). No statistically significant differences in safety outcomes were observed across interventions.Limitations: Twenty percent of eligible patients were not enrolled, and data on effectiveness outcomes were not collected before the trial.Conclusions: Both moderate-intensity and high-intensity guideline implementation strategies safely increased the proportion of low-risk patients with pneumonia who were treated as outpatients. The high-intensity strategy was most effective for increasing the performance of the recommended processes of care for outpatients and inpatients. [ABSTRACT FROM AUTHOR]

Background: Veterans who use VA pregnancy benefits may be at high risk for adverse pregnancy outcomes; however, little is known about rates of adverse pregnancy events or pregnancy-associated death among Veterans. Methods: We conducted a retrospective cohort study using VA national administrative data for Veterans ages 18-45 with at least one pregnancy outcome between October 2009 and September 2016 and a VA primary care visit within one year prior to pregnancy. We identified adverse events during pregnancy and up to 42 days after pregnancy and all-cause mortality within one year of pregnancy and compared prevalence of adverse events by Veteran race/ethnicity using adjusted logistic regression. Results: Pregnancies among Black Veterans had 69% higher odds of any adverse event than those among White Veterans (aOR = 1.69, 95% CI: 1.43, 2.00). All-cause mortality during pregnancy or within one year of pregnancy was recorded for 18 pregnancies, resulting in an estimated overall pregnancy-associated mortality rate of 76 deaths per 100,000 live births. Conclusions: We identified high overall rates of adverse pregnancy events and pregnancy-associated death among Veterans using VA benefits. As in non-VA populations, there were stark racial disparities in adverse pregnancy events among Veterans.

Objective: Many people report becoming pregnant while using contraception. Understanding more about this phenomenon may provide insight into pregnant people's responses to and healthcare needs for these pregnancies. This study explores the outcome (e.g., birth, miscarriage, abortion) of pregnancies among Veterans in which conception occurred in the month of contraceptive use. Study Design: We used data from the Examining Contraceptive Use and Unmet Need Study, a telephone-based survey conducted in 2014-2016 of women Veterans ( n = 2302) ages 18-44 receiving primary care from the Veterans Health Administration. For each pregnancy, we estimated the relationship between occurrence in the month of contraceptive use and the outcome of the pregnancy using multinomial logistic regression, controlling for relevant demographic, clinical, and military factors and clustering of pregnancies from the same Veteran. Results: The study included 4436 pregnancies from 1689 Veterans. Most participants were ≥30 years of age ( n = 1445, 85.6%), identified as non-Hispanic white ( n = 824, 51.6%), and lived in the Southern United States ( n = 994, 55.6%). Nearly 60% ( n = 1007) of Veterans who had ever been pregnant reported experiencing a pregnancy in the month of contraceptive use; a majority of those pregnancies ( n = 1354, 80.9%) were described as unintended. In adjusted models, pregnancies occurring in the month of contraceptive use were significantly more likely to end in abortion (aOR: 1.76, 95% CI: 1.42-2.18) than live birth. Conclusions: Pregnancy while using contraception is common among Veterans; these pregnancies are more likely to end in abortion than live birth. Given widespread restrictions to reproductive health services across much of the United States, ensuring Veterans' access to comprehensive care, including abortion, is critical to supporting reproductive autonomy and whole health.

Importance: Racial and ethnic disparities exist in anticoagulation therapy for atrial fibrillation (AF). Whether medical center racial and ethnic composition is associated with these disparities is unclear., Objective: To determine whether medical center racial and ethnic composition is associated with overall anticoagulation and disparities in anticoagulation for AF., Design, Setting, and Participants: Retrospective cohort study of Black, White, and Hispanic patients with incident AF from 2018 to 2021 at 140 Veterans Health Administration medical centers (VAMCs). Data were analyzed from March to November 2023., Exposure: VAMC racial and ethnic composition, defined as the proportion of patients from minoritized racial and ethnic groups treated at a VAMC, categorized into quartiles. VAMCs in quartile 1 (Q1) had the lowest percentage of patients from minoritized groups (ie, the reference group)., Main Outcomes and Measures: The odds of initiating any anticoagulant, direct-acting oral anticoagulant (DOAC), or warfarin therapy within 90 days of an index AF diagnosis, adjusting for sociodemographics, medical comorbidities, and facility factors., Results: The cohort comprised 89 791 patients with a mean (SD) age of 73.0 (10.1) years; 87 647 (97.6%) were male, 9063 (10.1%) were Black, 3355 (3.7%) were Hispanic, and 77 373 (86.2%) were White. Overall, 64 770 individuals (72.1%) initiated any anticoagulant, 60 362 (67.2%) initiated DOAC therapy, and 4408 (4.9%) initiated warfarin. Compared with White patients, Black and Hispanic patients had lower rates of any anticoagulant and DOAC therapy initiation but higher rates of warfarin initiation across all quartiles of VAMC racial and ethnic composition. Any anticoagulant therapy initiation was lower in Q4 than Q1 (69.8% vs 74.9%; adjusted odds ratio [aOR], 0.80; 95% CI, 0.69-0.92; P < .001). DOAC and warfarin initiation were also lower in Q4 than in Q1 (DOAC, 69.4% vs 65.3%; aOR, 0.85; 95% CI, 0.74-0.97; P < .001; warfarin, 5.4% vs 4.5%; aOR, 0.82; 95% CI, 0.67-1.00; P < .001). In adjusted models, patients in Q4 were significantly less likely to initiate any anticoagulant therapy than those in Q1 (aOR, 0.88; 95% CI, 0.78-0.99). Patients in Q3 (aOR, 0.75; 95% CI, 0.60-0.93) and Q4 (aOR, 0.69; 95% CI, 0.55-0.87) were significantly less likely to initiate warfarin therapy than those in Q1. There was no significant difference in the adjusted odds of initiating DOAC therapy across racial and ethnic composition quartiles. Although significant Black-White and Hispanic-White differences in initiation of any anticoagulant, DOAC, and warfarin therapy were observed, interactions between patient race and ethnicity and VAMC racial composition were not significant., Conclusions and Relevance: In a national cohort of VA patients with AF, initiation of any anticoagulant and warfarin, but not DOAC therapy, was lower in VAMCs serving more minoritized patients.

Objective: To understand the determinants and benefits of cross-sector partnerships between Veterans Affairs Medical Centers (VAMCs) and geographically affiliated AmericaServes Network coordination centers that address Veteran health-related social needs., Data Sources and Setting: Semi-structured interviews were conducted with AmericaServes and VAMC staff across seven regional networks. We matched administrative data to calculate the percentage of AmericaServes referrals that were successfully resolved (i.e., requested support was provided) in each network overall and stratified by whether clients were also VAMC patients., Study Design: Convergent parallel mixed-methods study guided by Himmelman's Developmental Continuum of Change Strategies (DCCS) for interorganizational collaboration., Data Collection: Fourteen AmericaServes staff and 17 VAMC staff across seven networks were recruited using snowball sampling and interviewed between October 2021 and April 2022. Rapid qualitative analysis methods were used to characterize the extent and determinants of VAMC participation in networks., Principal Findings: On the DCCS continuum of participation, three networks were classified as networking, two as coordinating, one as cooperating, and one as collaborating. Barriers to moving from networking to collaborating included bureaucratic resistance to change, VAMC leadership buy-in, and not having VAMCs staff use the shared technology platform. Facilitators included ongoing communication, a shared mission of serving Veterans, and having designated points-of-contact between organizations. The percentage of referrals that were successfully resolved was lowest in networks engaged in networking (65.3%) and highest in cooperating (85.6%) and collaborating (83.1%) networks. For coordinating, cooperating, and collaborating networks, successfully resolved referrals were more likely among Veterans who were also VAMC patients than among Veterans served only by AmericaServes., Conclusions: VAMCs participate in AmericaServes Networks at varying levels. When partnerships are more advanced, successful resolution of referrals is more likely, especially among Veterans who are dually served by both organizations. Although challenges to establishing partnerships exist, this study highlights effective strategies to overcome them., (Published 2024.

Background: Oral anticoagulation reduces stroke risk for patients with atrial fibrillation (AF). Prior research demonstrates lower anticoagulant prescribing in Black than in White individuals but few studies have examined racial differences in facility-level anticoagulant prescribing for AF., Objective: To assess variation in anticoagulant initiation by race within Veterans Health Administration (VA) facilities., Design: Retrospective cohort study., Participants: Black and White patients enrolled in the VA with incident AF from 2020 through 2021., Main Measures: The primary outcome was rate of any anticoagulant initiation (i.e., warfarin or direct oral anticoagulant [DOAC]) or any DOAC therapy within 90 days of an AF diagnosis, overall and for Black and White patients at each facility. We also estimated the adjusted Black-White risk difference., Key Results: In 82 VA facilities serving 26,832 Black and White patients, overall unadjusted rates of any anticoagulant therapy ranged from 56.8 to 87.1% across facilities; the corresponding ranges for Black and White patients were 47.6 to 91.3% and 58.2 to 87.1%, respectively. Overall unadjusted rates of DOAC therapy ranged from 55.1 to 85.5% by facility; ranges for Black and White patients were 42.8 to 86.9% and 56.4 to 85.5%, respectively. The adjusted risk difference between Black and White patients ranged from - 29.9 (95% CI, - 54.9 to - 4.8) to 14.2 (95% CI, - 9.1 to 25.0) across facilities for any anticoagulant therapy and from - 28.8 (95% CI, - 58.3 to 0.8) to 15.0 (95% CI, - 8.0 to 38.1) for DOAC therapy. For any anticoagulant therapy there were 3 facilities where prescribing was statistically higher in White than Black patients; for DOAC therapy there were 5 such facilities., Conclusions: In a national cohort of patients with AF, we observed large facility-level variation and adjusted risk differences in any anticoagulant and DOAC initiation, overall and by race. These findings represent a target for local quality improvement in AF care., (© 2024.

Background: Elder abuse (EA) is common and has devastating health impacts. Frailty may increase susceptibility to and consequences of EA for older adults, making healthcare system detection more likely, but this relationship has been difficult to study. We examined the association between a recently validated frailty index and referral to social work (SW) for EA evaluation in the Veterans Administration (VA) healthcare system., Methods: We conducted a case-control study of veterans aged ≥60 years evaluated by SW for suspected EA between 2010 and 2018 (n = 14,723) and controls receiving VA primary care services in the same 60-day window (n = 58,369). We used VA and Medicare claims data to measure frailty (VA Frailty Index) and comorbidity burden (the Elixhauser Comorbidity Index) in the 2 years prior to the index. We used adjusted logistic regression models to examine the association of frailty or comorbidity burden with referral to SW for EA evaluation. We used Akaike Information Criterion (AIC) values to evaluate model fit and likelihood ratio (LR) tests to assess the statistical significance of including frailty and comorbidity in the same model., Results: The sample (n = 73,092) had a mean age 72 years; 14% were Black, and 6% were Hispanic. More cases (67%) than controls (36%) were frail. LR tests comparing the nested models were highly significant (p < 0.001), and AIC values indicated superior model fit when including both frailty and comorbidity in the same model. In a model adjusting for comorbidity and all covariates, pre-frailty (aOR vs. robust 1.7; 95% CI 1.5-1.8) and frailty (aOR vs. robust 3.6; 95% CI 3.3-3.9) were independently associated with referral for EA evaluation., Conclusions: A claims-based measure of frailty predicted referral to SW for EA evaluation in a national healthcare system, independent of comorbidity burden. Electronic health record measures of frailty may facilitate EA risk assessment and detection for this important but under-recognized phenomenon., (© 2023 The American Geriatrics Society.

Objective: Evaluate self-reported electronic screening ( eScreening ) in a VA Transition Care Management Program (TCM) to improve the accuracy and completeness of administrative ethnicity and race data., Materials and Methods: We compared missing, declined, and complete (neither missing nor declined) rates between (1) TCM-eScreening (ethnicity and race entered into electronic tablet directly by patient using eScreening), (2) TCM-EHR (Veteran-completed paper form plus interview, data entered by staff), and (3) Standard-EHR (multiple processes, data entered by staff). The TCM-eScreening ( n  = 7113) and TCM-EHR groups ( n  = 7113) included post-9/11 Veterans. Standard-EHR Veterans included all non-TCM Gulf War and post-9/11 Veterans at VA San Diego ( n  = 92 921)., Results: Ethnicity : TCM-eScreening had lower rates of missingness than TCM-EHR and Standard-EHR (3.0% vs 5.3% and 8.6%, respectively, P  < .05), but higher rates of "decline to answer" (7% vs 0.5% and 1.2%, P  < .05). TCM-EHR had higher data completeness than TCM-eScreening and Standard-EHR (94.2% vs 90% and 90.2%, respectively, P  < .05). Race : No differences between TCM-eScreening and TCM-EHR for missingness (3.5% vs 3.4%, P  > .05) or data completeness (89.9% vs 91%, P  > .05). Both had better data completeness than Standard-EHR ( P  < .05), which despite the lowest rate of "decline to answer" (3%) had the highest missingness (10.3%) and lowest overall completeness (86.6%). There was strong agreement between TCM-eScreening and TCM-EHR for ethnicity (Kappa = .92) and for Asian, Black, and White Veteran race (Kappas = .87 to .97), but lower agreement for American Indian/Alaska Native (Kappa = .59) and Native Hawaiian/Other Pacific Islander (Kappa = .50) Veterans., Conculsions: eScreening is a promising method for improving ethnicity and race data accuracy and completeness in VA., Competing Interests: None declared., (Published by Oxford University Press on behalf of the American Medical Informatics Association 2023.)

Significance Statement: Of studies reporting an association of CKD with lower use of invasive cardiac care to treat acute coronary syndrome (ACS), just one accounted for the appropriateness of such care. However, its findings in patients hospitalized nearly 30 years ago may not apply to current practice. In a more recent cohort of 64,695 veterans hospitalized with ACS, CKD was associated with a 32% lower likelihood of receiving invasive care determined to be clinically indicated. Among patients with CKD, not receiving such care was associated with a 1.39-fold higher risk of 6-month mortality. Efforts to elucidate the reasons for this disparity in invasive care in patients with ACS and CKD and implement tailored interventions to enhance its use in this population may offer the potential to improve clinical outcomes., Background: Previous studies have shown that patients with CKD are less likely than those without CKD to receive invasive care to treat acute coronary syndrome (ACS). However, few studies have accounted for whether such care was clinically indicated or assessed whether nonuse of such care was associated with adverse health outcomes., Methods: We conducted a retrospective cohort study of US veterans who were hospitalized at Veterans Affairs Medical Centers from January 2013 through December 2017 and received a discharge diagnosis of ACS. We used multivariable logistic regression to investigate the association of CKD with use of invasive care (coronary angiography, with or without revascularization; coronary artery bypass graft surgery; or both) deemed clinically indicated based on Global Registry of Acute Coronary Events 2.0 risk scores that denoted a 6-month predicted all-cause mortality ≥5%. Using propensity scoring and inverse probability weighting, we examined the association of nonuse of clinically indicated invasive care with 6-month all-cause mortality., Results: Among 34,430 patients with a clinical indication for invasive care, the 18,780 patients with CKD were less likely than the 15,650 without CKD to receive such care (adjusted odds ratio, 0.68; 95% confidence interval, 0.65 to 0.72). Among patients with CKD, nonuse of invasive care was associated with higher risk of 6-month all-cause mortality (absolute risk, 21.5% versus 15.5%; absolute risk difference 6.0%; adjusted risk ratio, 1.39; 95% confidence interval, 1.29 to 1.49). Findings were consistent across multiple sensitivity analyses., Conclusions: In contemporary practice, veterans with CKD who experience ACS are less likely than those without CKD to receive clinically indicated invasive cardiac care. Nonuse of such care is associated with increased mortality., (Copyright © 2023 by the American Society of Nephrology.)

Background: Atrial fibrillation (AF) is a common arrhythmia, the management of which includes anticoagulation for stroke prevention. Although disparities in anticoagulant prescribing have been well documented for individual socioeconomic factors, less is known about the association of neighborhood-level disadvantage and anticoagulation for AF., Objective: To assess the association between neighborhood disadvantage and anticoagulant initiation for patients with incident AF., Design: Retrospective cohort study., Participants: A cohort of patients enrolled in the Veterans Health Administration (VA) with incident AF from January 2014 through December 2020 from the Race, Ethnicity, and Anticoagulant CHoice in Atrial Fibrillation (REACH-AF) Study., Main Measures: The primary exposure was neighborhood disadvantage quantified using area deprivation index (ADI), classified by quintiles (Q). The outcomes were initiation of any anticoagulant therapy (warfarin or direct oral anticoagulant, DOAC) within 90 days of AF diagnosis and DOAC use among initiators. We used mixed effects logistic regression to assess the association between ADI and anticoagulant therapy, incorporating a fixed effect for treatment site and baseline patient, provider, and facility covariates., Key Results: Among 161,089 patients, 105,489 (65.5%) initiated any anticoagulant therapy, and 78,903 (74.8%) used DOACs. Any anticoagulant therapy increased 3.2 percentage points (63.0% to 66.2%; p<.001) from Q1 to Q5, whereas DOAC use decreased 8.2 percentage points (79.4% to 71.2%; p<.0001) across quintiles. The adjusted odd ratios of any anticoagulant therapy were non-significantly different for Q2-Q5 than Q1. The adjusted odds of DOAC use decreased progressively from 0.89 (95% CI, 0.84-0.94) in Q2 to 0.77 (95% CI, 0.73-0.83) in Q5 compared to Q1 (p<.0001)., Conclusions: Among Veterans with incident AF, we observed similar initiation of any anticoagulant, though neighborhood deprivation was associated with decreased DOAC use among anticoagulant initiators. Future interventions to improve pharmacoequity in anticoagulant prescribing for AF should consider the role of neighborhood-level determinants of health inequities., (© 2022.

Background: The Veterans Health Administration (VHA) developed the Stratification Tool for Opioid Risk Mitigation (STORM) dashboard to assist in identifying Veterans at risk for adverse opioid overdose or suicide-related events. In 2018, a policy was implemented requiring VHA facilities to complete case reviews of Veterans identified by STORM as very high risk for adverse events. Nationally, facilities were randomized in STORM implementation to four arms based on required oversight and by the timing of an increase in the number of required case reviews. To help evaluate this policy intervention, we aimed to (1) identify barriers and facilitators to implementing case reviews; (2) assess variation across the four arms; and (3) evaluate associations between facility characteristics and implementation barriers and facilitators., Method: Using the Consolidated Framework for Implementation Research (CFIR), we developed a semi-structured interview guide to examine barriers to and facilitators of implementing the STORM policy. A total of 78 staff from 39 purposefully selected facilities were invited to participate in telephone interviews. Interview transcripts were coded and then organized into memos, which were rated using the -2 to + 2 CFIR rating system. Descriptive statistics were used to evaluate the mean ratings on each CFIR construct, the associations between ratings and study arm, and three facility characteristics (size, rurality, and academic detailing) associated with CFIR ratings. We used the mean CFIR rating for each site to determine which constructs differed between the sites with highest and lowest overall CFIR scores, and these constructs were described in detail., Results: Two important CFIR constructs emerged as barriers to implementation: Access to knowledge and information and Evaluating and reflecting. Little time to complete the CASE reviews was a pervasive barrier. Sites with higher overall CFIR scores showed three important facilitators: Leadership engagement, Engaging, and Implementation climate. CFIR ratings were not significantly different between the four study arms, nor associated with facility characteristics. Plain Language Summary: The Veterans Health Administration (VHA) created a tool called the Stratification Tool for Opioid Risk Mitigation dashboard. This dashboard shows Veterans at risk for opioid overdose or suicide-related events. In 2018, a national policy required all VHA facilities to complete case reviews for Veterans who were at high risk for these events. To evaluate this policy implementation, 78 staff from 39 facilities were interviewed. The Consolidated Framework for Implementation Research (CFIR) implementation framework was used to create the interview. Interview transcripts were coded and organized into site memos. The site memos were rated using CFIR's -2 to +2 rating system. Ratings did not differ for four study arms related to oversight and timing. Ratings were not associated with facility characteristics. Leadership, engagement and implementation climate were the strongest facilitators for implementation. Lack of time, knowledge, and feedback were important barriers., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Background: Elder abuse (EA) is common and has devastating health consequences yet is not systematically assessed or documented in most health systems, limiting efforts to target health care-based interventions. Our objective was to examine sociodemographic and medical characteristics associated with documented referrals for EA assessment or services in a national U.S. health care system., Methods: We conducted a national case-control study in U.S. Veterans Health Administration facilities of primary care (PC)-engaged Veterans age ≥60 years who were evaluated by social work (SW) for EA-related concerns between 2010 and 2018. Cases were matched 1:5 to controls with a PC visit within 60 days of the matched case SW encounter. We examined the association of patient sociodemographic and health factors with receipt of EA services in unadjusted and adjusted models., Results: Of 5 567 664 Veterans meeting eligibility criteria during the study period, 15 752 (0.3%) received services for EA (cases). Cases were mean age 74, and 54% unmarried. In adjusted logistic regression models (adjusted odds ratio; 95% confidence interval), age ≥ 85 (3.56 vs age 60-64; 3.24-3.91), female sex (1.96; 1.76-2.21), child as next-of-kin (1.70 vs spouse; 1.57-1.85), lower neighborhood socioeconomic status (1.18 per higher quartile; 1.15-1.21), dementia diagnosis (3.01; 2.77-3.28), and receiving a VA pension (1.34; 1.23-1.46) were associated with receiving EA services., Conclusion: In the largest cohort of patients receiving EA-related health care services studied to date, this study identified novel factors associated with clinical suspicion of EA that can be used to inform improvements in health care-based EA surveillance and detection., (Published by Oxford University Press on behalf of The Gerontological Society of America 2021.)

Background: Although the PSI and CURB-65 represent well-validated prediction rules for pneumonia prognosis, PSI was designed to identify patients at low risk and CURB- 65 patients at high risk of mortality. We compared the prognostic performance of a modified version of the PSI designed to identify high-risk patients (i.e., PSI-HR) to CURB-65 in predicting short-term mortality., Methods: Using data from 6 pneumonia cohorts, we designed PSI-HR as a 6-class prediction rule using the original prognostic weights of all PSI variables and modifying the risk score thresholds to define risk classes. We calculated the proportion of low-risk and high-risk patients using CURB-65 and PSI-HR and 30-day mortality in these subgroups. We compared the rules' sensitivity, specificity, positive and negative predictive values for mortality at all risk class thresholds and assessed discriminatory power using areas under their receiver operating characteristic curves (AUROCs)., Results: Among 13,874 patients with pneumonia, 1,036 (7.5%) died. For PSI-HR versus CURB-65, aggregate mortality was lower in low-risk patients (1.6% vs. 2.2%, p = 0.005) and higher in high-risk patients (36.5% vs. 32.2%, p = 0.27). PSI-HR had higher sensitivities than CURB-65 at all thresholds; PSI-HR also had higher specificities at the 3 lowest thresholds and specificities within 0.5% points of CURB-65 at the 2 highest thresholds. The AUROC was larger for PSI-HR than CURB- 65 (0.82 vs. 0.77, p < 0.0001)., Conclusions: PSI-HR demonstrated superior prognostic accuracy to CURB-65 at the lower end of the severity spectrum and identified high-risk patients with nonsignificant higher short-term mortality at the higher end., Competing Interests: Declaration of competing interest None., (Crown Copyright © 2022.

Objective: Guidelines advocate against tight glycemic control in older nursing home (NH) residents with advanced dementia (AD) or limited life expectancy (LLE). We evaluated the effect of deintensifying diabetes medications with regard to all-cause emergency department (ED) visits, hospitalizations, and death in NH residents with LLE/AD and tight glycemic control., Research Design and Methods: We conducted a national retrospective cohort study of 2,082 newly admitted nonhospice veteran NH residents with LLE/AD potentially overtreated for diabetes (HbA1c ≤7.5% and one or more diabetes medications) in fiscal years 2009-2015. Diabetes treatment deintensification (dose decrease or discontinuation of a noninsulin agent or stopping insulin sustained ≥7 days) was identified within 30 days after HbA1c measurement. To adjust for confounding, we used entropy weights to balance covariates between NH residents who deintensified versus continued medications. We used the Aalen-Johansen estimator to calculate the 60-day cumulative incidence and risk ratios (RRs) for ED or hospital visits and deaths., Results: Diabetes medications were deintensified for 27% of residents. In the subsequent 60 days, 28.5% of all residents were transferred to the ED or acute hospital setting for any cause and 3.9% died. After entropy weighting, deintensifying was not associated with 60-day all-cause ED visits or hospitalizations (RR 0.99 [95% CI 0.84, 1.18]) or 60-day mortality (1.52 [0.89, 2.81])., Conclusions: Among NH residents with LLE/AD who may be inappropriately overtreated with tight glycemic control, deintensification of diabetes medications was not associated with increased risk of 60-day all-cause ED visits, hospitalization, or death., (© 2022 by the American Diabetes Association.)

Background: Alcohol use is a significant risk factor for disability and death in U.S. adults, and approximately one out of every six Veterans seen in primary care (PC) report unhealthy alcohol use. Unhealthy alcohol use is associated with increased risk for poor medical outcomes, substantial societal costs, and death, including suicide. Based on substantial evidence from randomized controlled trials and the U.S. Preventive Services Task Force, VA/DoD clinical guidelines stipulate that all Veterans screening positive for unhealthy alcohol use should receive evidence-based alcohol care in PC, including brief counseling interventions (BI) and additional treatment (e.g., pharmacotherapy) for those with alcohol use disorders (AUD). The VA pioneered implementing alcohol screening and BI in PC, yet substantial implementation gaps remain. To improve alcohol-related care, this study will conduct a pilot study to assess whether a multi-faceted evidence-based implementation strategy-practice facilitation-has the potential to improve PC-based alcohol-related care at a single VA clinic., Methods: We will first recruit and conduct qualitative interviews with Veterans with unhealthy alcohol use (n = 20-25) and PC stakeholders (N = 10-15) to understand barriers and facilitators to high-quality alcohol care and use results to refine and hone the multifaceted practice facilitation intervention. Qualitative interviews, analysis, and refinement of the intervention will be guided by the Consolidated Framework for Implementation Research (CFIR). Focus groups with a small sample of PC providers and staff (n = 5-7) will be used to further refine the practice facilitation intervention and assess its acceptability and feasibility. The refined practice facilitation intervention will then be offered in the PC clinic to assess implementation (e.g., reach) and effectiveness (reduced drinking) outcomes based on the RE-AIM framework., Discussion: This research directly addresses one of the largest public health crises of our time, as alcohol kills more people than opioids and is associated with increased risk of suicide. If successful, this pilot may generate an intervention with far-reaching effects on adverse outcomes experienced by Veterans with unhealthy alcohol use, including increased access to care and suicide prevention.

Background: Racial and ethnic disparities in anticoagulation exist in atrial fibrillation management in Medicare and the Veterans Health Administration, but the influence of dual Veterans Health Administration and Medicare enrollment is unclear. We compared anticoagulant initiation by race and ethnicity in dually enrolled patients and assessed the role of Medicare part D enrollment on anticoagulation disparities., Methods: We identified patients with incident atrial fibrillation (2014-2018) dually enrolled in Veterans Health Administration and Medicare. We assessed any anticoagulant initiation (warfarin or direct-acting oral anticoagulants [DOACs]) within 90 days of atrial fibrillation diagnosis and DOAC use among anticoagulant initiators. We modeled anticoagulant initiation, adjusting for patient, provider, and facility factors, including main effects for race and ethnicity and Medicare part D enrollment and an interaction term for these variables., Results: In 43 789 patients, 8.9% were Black, 3.6% Hispanic, and 87.5% White; 10.9% participated in Medicare part D. Overall, 29 680 (67.8%) patients initiated any anticoagulant, of whom 17 568 (59.2%) initiated DOACs. Lower proportions of Black (65.2%) than Hispanic (67.6%) or White (68.0%) patients initiated any anticoagulant ( P =0.001) and, lower proportions of Black (56.3%) and Hispanic (55.9%) than White (59.6%) patients ( P =0.001) initiated DOACs. Compared with White patients, Black patients had significantly lower initiation of any anticoagulant (adjusted odds ratio, 0.89 [95% CI, 0.82-0.97]). The adjusted odds ratios for DOAC initiation were significantly lower for Black (0.72 [95% CI, 0.65-0.81]) and Hispanic (0.84 [95% CI, 0.70-1.00]) than White patients. The interaction between race and ethnicity and Medicare part D enrollment was nonsignificant for any anticoagulant ( P =0.99) and DOAC ( P =0.27) therapies., Conclusions: In dually enrolled Veterans Health Administration and Medicare patients with atrial fibrillation, Black patients were less likely to initiate any anticoagulant, and Black and Hispanic patients were less likely to initiate DOACs. Medicare part D enrollment did not moderate the associations between race and ethnicity and anticoagulant therapies.

Background: Most states have recently passed laws requiring prescribers to use prescription drug monitoring programs (PDMPs) before prescribing opioid medications. The impact of these mandates on discontinuing chronic opioid therapy among Veterans managed in the Veterans Health Administration (VA) is unknown. We assess the association between the earliest of these laws and discontinuation of chronic opioid therapy in Veterans receiving VA health care., Methods: We conducted a comparative interrupted time-series study in the 5 states mandating PDMP use before August 2013 (Ohio, West Virginia, Kentucky, New Mexico, and Tennessee), adjusting for trends in the 17 neighboring control states without such mandates. We modeled 25 months of prescribing for each state centered on the month the mandate became effective. We included Veterans prescribed long-term outpatient opioid therapy (305 of the preceding 365 d). Our outcomes were discontinuation of chronic opioid therapy (primary outcome) and the average daily quantity of opioids per Veteran over the following 6 months (secondary outcome)., Results: We included 250 monthly cohorts with 225,665 unique Veterans and 3.4 million Veteran-months. Baseline discontinuation rates before the PDMP mandates were 0.4%-2.7% per month. Kentucky saw a discontinuation increase of 1 absolute percentage point following its PDMP mandate which decreased over time. The other 4 states had no significant association between their mandates and change in opioid discontinuation. There was no evidence of decreasing opioid quantities following PDMP mandates., Conclusion: We did not find consistent evidence that state laws mandating provider PDMP use were associated with the discontinuation of chronic opioid therapy within the VA for the time period studied., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background: Patients with diabetes (PWD) often experience diabetes distress which is associated with worse self-management and glycemic control. In contrast, PWD who receive support from family and friends (supporters) have better diabetes outcomes., Purpose: To examine the associations of PWD diabetes distress and supporters' distress about PWDs' diabetes with supporters' roles and PWD cardiometabolic outcomes., Methods: We used baseline data from 239 adults with Type 2 diabetes and their supporters participating in a longitudinal trial. PWD and supporter diabetes distress (high vs. low) were determined using the Problem Areas in Diabetes Scale-5. Outcomes included PWD-reported help from supporters with self-care activities, supporter-reported strain, PWD metabolic outcomes (glycemic control [HbA1c], systolic blood pressure [SBP], and non-HDL cholesterol) and 5 and 10 year risk of cardiac event (calculated using the United Kingdom Prospective Diabetes Study algorithm)., Results: PWDs with high diabetes distress were more likely to report that their supporters helped with taking medications, coordinating medical care, and home glucose testing (p's < .05), but not more likely to report help with diet or exercise. High supporter distress was associated with greater supporter strain (p < .001). High supporter diabetes distress was associated with higher PWD HbA1c (p = .045), non-HDL cholesterol (p = .011), and 5 (p = .002) and 10 year (p = .001) cardiac risk., Conclusions: Adults with high diabetes distress report more supporter help with medically focused self-management but not with diet and exercise. Supporter distress about PWD diabetes was consistently associated with worse outcomes. PWD diabetes distress had mixed associations with their diabetes outcomes., (© Society of Behavioral Medicine 2020. All rights reserved.

Importance: Atrial fibrillation is a common cardiac rhythm disturbance causing substantial morbidity and mortality that disproportionately affects racial/ethnic minority groups. Anticoagulation reduces stroke risk in atrial fibrillation, yet studies show it is underprescribed in racial/ethnic minority patients., Objective: To compare initiation of anticoagulant therapy by race/ethnicity for patients in the Veterans Health Administration (VA) system with atrial fibrillation., Design, Setting, and Participants: This retrospective cohort study included 111 666 patients within the VA system with incident atrial fibrillation between January 1, 2014, and December 31, 2018. Data were analyzed between December 1, 2019, and March 31, 2020., Exposures: Any anticoagulation was defined as receipt of warfarin or direct-acting oral anticoagulants, apixaban, dabigatran, edoxaban, or rivaroxaban., Main Outcomes and Measures: Initiation of any anticoagulation (or direct-acting oral anticoagulant therapy in those who initiated any anticoagulation) was examined within 90 days of an index atrial fibrillation diagnosis., Results: Our final cohort comprised 111 666 patients (109 386 men [98.0%] and 95 493 White patients [85.5%]; mean [SD] age, 72.9 [10.4] years). A total of 69 590 patients (62.3%) initiated any anticoagulant therapy, varying 10.5 percentage points by race/ethnicity (P < .001); initiation was lowest in Asian (52.2% [n = 676]) and Black (60.3% [n = 6177]) patients and highest in White patients (62.7% [n = 59 881]). Among anticoagulant initiators, 45 381 (65.2%) used direct-acting oral anticoagulants, varying 7.2 percentage points by race/ethnicity (P < .001); initiation was lowest in Hispanic (58.3% [n = 1470]), American Indian/Alaska Native (59.8% [n = 201]), and Black (60.9% [n = 3763]) patients and highest in White patients (66.0% [n = 39 502). Compared with White patients, the odds of initiating any anticoagulant therapy were significantly lower for Asian (adjusted odds ratio [aOR], 0.82; 95% CI, 0.72-0.94) and Black (aOR, 0.90; 95% CI 0.85-0.95) patients. Among initiators, the adjusted odds of direct-acting oral anticoagulant initiation were significantly lower for Hispanic (aOR, 0.79; 95% CI, 0.70-0.89), American Indian/Alaska Native (aOR, 0.75; 95% CI, 0.57-0.99), and Black (aOR, 0.74; 95% CI 0.69-0.80) patients., Conclusions and Relevance: This cohort study found that in patients with incident atrial fibrillation managed in the VA system, race/ethnicity was independently associated with initiating any anticoagulant therapy and direct-acting oral anticoagulant use among anticoagulant initiators. Understanding the reasons for these treatment disparities is essential to improving equitable atrial fibrillation management and outcomes among racial/ethnic minority patients treated in the VA system.

Introduction: Among adults with Type 2 diabetes, low health literacy (HL) is a risk factor for negative health outcomes. Support from family and friends can improve adults' self-management and health-related outcomes. We examined whether supporters provided unique help to adults with diabetes and low HL and whether HL was associated with adults' perception of supporter helpfulness., Methods: We used cross-sectional baseline survey data from 239 adult patients with diabetes enrolled in a randomized controlled trial with a support person. Patients reported level of supporter involvement with self-management roles. HL among patients and supporters was assessed using a validated HL screening tool. Patient perception of supporter helpfulness was assessed with a single item. We used multivariable logistic regression to examine associations of patient and supporter HL levels with supporter roles and patients' perception of supporter helpfulness., Results: Patients with low HL were more likely to have a supporter with low HL (39% vs. 26%, p = .04). Patients with low HL had higher odds of receiving supporter help with calling health care providers (adjusted odds ratio [AOR] = 2.09, 95% CI [1.00, 4.39]), remembering medical appointments (AOR = 2.24, 95% CI [1.07, 4.69]), and giving directions when blood sugars were low (AOR = 2.51, 95% CI [1.20, 5.37]). Neither patient nor supporter HL was significantly associated with patients' perception of supporter helpfulness., Discussion: Adults with diabetes and low HL reported more supporter involvement with specific self-management tasks than patients with adequate HL. Providers could consider targeted involvement of supporters to assist patients with chronic diseases and low HL, although they should be aware that supporters may be challenged by low HL.

Background: Compared to White patients in the United States, Black patients have a higher prevalence of hypertension and more severe forms of this condition., Objective: To decrease racial disparities in blood pressure (BP) control among Black veterans with severe hypertension within a regional network of Veterans Affairs Medical Centers (VAMCs)., Methods: Health system leaders, clinicians, and health services researchers collaborated on a 12-month quality improvement (QI) project to: (1) examine project implementation and the QI strategies used to improve BP control and (2) assess the effect of the initiative on Black-White differences in BP control among veterans with severe hypertension., Results: Within 9 participating VAMCs, the most frequently used QI strategies involved provider education (n=9), provider audit and feedback (n=8), and health care team change (n=7). Among 141,124 veterans with a diagnosis of hypertension, 9,913 had severe hypertension [2,533 (25.6%) Black and 7380 (74.4%) White]. Over the course of the project, the proportion of Black veterans with severe hypertension decreased from 7.5% to 6.6% (p=.002) and the racial difference in proportions for this condition decreased 0.9 percentage points, from 2.9% to 2.0% (p=.01)., Conclusions: A multicenter, equity-focused QI project in VA reduced the proportion of Black veterans with severe hypertension and ameliorated observed racial disparities for this condition. Embedding health services researchers within a QI team facilitated an evaluation of the processes and effectiveness of our initiative, providing a successful model for QI within a learning health care system., (Copyright © 2020 Elsevier Inc.

Background: Post-9/11 veterans who enroll in VA health care frequently present with suicidal ideation and/or recent suicidal behavior. Most of these veterans are not screened on their day of enrollment and their risk goes undetected. Screening for suicide risk, and associated mental health factors, can lead to early detection and referral to effective treatment, thereby decreasing suicide risk. eScreening is an innovative Gold Standard Practice with evidence to support its effectiveness and implementation potential in transition and care management (TCM) programs. We will evaluate the impact of eScreening to improve the rate and speed of suicide risk screening and referral to mental health care compared to current screening methods used by transition care managers. We will also evaluate the impact of an innovative, multicomponent implementation strategy (MCIS) on the reach, adoption, implementation, and sustained use of eScreening., Methods: This is an eight-site 4-year, stepped-wedge, mixed-method, hybrid type-II implementation trial comparing eScreening to screening as usual while also evaluating the potential impact of the MCIS focusing on external facilitation and Lean/SixSigma rapid process improvement workshops in TCM. The aims will address: 1) whether using eScreening compared to oral and/or paper-based methods in TCM programs is associated with improved rates and speed of PTSD, depression, alcohol, and suicide screening & evaluation, and increased referral to mental health treatment; 2) whether and to what degree our MCIS is feasible, acceptable, and has the potential to impact adoption, implementation, and maintenance of eScreening; and 3) how contextual factors influence the implementation of eScreening between high- and low-eScreening adopting sites. We will use a mixed methods approach guided by the RE-AIM outcomes of the Practical Robust Implementation and Sustainability Model (PRISM). Data to address Aim 1 will be collected via medical record query while data for Aims 2 and 3 will be collected from TCM staff questionnaires and qualitative interviews., Discussion: The results of this study will help identify best practices for screening in suicide prevention for Post-9/11 veterans enrolling in VA health care and will provide information on how best to implement technology-based screening into real-world clinical care programs., Trial Registration: ClinicalTrials.gov : NCT04506164; date registered: August 20, 2020; retrospectively registered.

This study examined the role of autonomy support from adults' informal health supporters (family or friends) in diabetes-specific health behaviors and health outcomes. Using baseline data from 239 Veterans with type 2 diabetes at risk of complications enrolled in behavioral trial, we examined associations between autonomy support from a support person and that support person's co-residence with the participant's diabetes self-care activities, patient activation, cardiometabolic measures, and predicted risk of a cardiac event. Autonomy support from supporters was associated with significantly increased adherence to healthy lifestyle behaviors (diet, p < .001 and exercise, p = .003); higher patient activation (p < .001); greater patient efficacy in interacting with healthcare providers, and lower 5-year (p = .044) and 10-year (p = .027) predicted cardiac risk. Autonomy support was not significantly associated with diabetes-specific behaviors (checking blood glucose, foot care, or medication taking); or hemoglobin A1c, systolic blood pressure, or non-HDL cholesterol. There was a significant interaction of autonomy support and supporter residence in one model such that lack of autonomy support was associated with lower patient activation only among individuals with in-home supporters. No other interactions were significant. Findings suggest that autonomy support from family and friends may play a role in patient self-management, patient activation, and lower cardiac risk.

Background and Objectives: Many kidney transplant recipients enrolled in the Veterans Health Administration are also enrolled in Medicare and eligible to receive both Veterans Health Administration and private sector care. Where these patients receive transplant care and its association with mortality are unknown., Design, Setting, Participants, & Measurements: We conducted a retrospective cohort study of veterans who underwent kidney transplantation between 2008 and 2016 and were dually enrolled in Veterans Health Administration and Medicare at the time of surgery. We categorized patients on the basis of the source of transplant-related care ( i.e ., outpatient transplant visits, immunosuppressive medication prescriptions, calcineurin inhibitor measurements) delivered during the first year after transplantation defined as Veterans Health Administration only, Medicare only ( i.e ., outside Veterans Health Administration using Medicare), or dual care (mixed use of Veterans Health Administration and Medicare). Using multivariable Cox regression, we examined the independent association of post-transplant care source with mortality at 5 years after kidney transplantation., Results: Among 6206 dually enrolled veterans, 975 (16%) underwent transplantation at a Veterans Health Administration hospital and 5231 (84%) at a non-Veterans Health Administration hospital using Medicare. Post-transplant care was received by 752 patients (12%) through Veterans Health Administration only, 2092 (34%) through Medicare only, and 3362 (54%) through dual care. Compared with patients who were Veterans Health Administration only, 5-year mortality was significantly higher among patients who were Medicare only (adjusted hazard ratio, 2.2; 95% confidence interval, 1.5 to 3.1) and patients who were dual care (adjusted hazard ratio, 1.5; 95% confidence interval, 1.1 to 2.1)., Conclusions: Most dually enrolled veterans underwent transplantation at a non-Veterans Health Administration transplant center using Medicare, yet many relied on Veterans Health Administration for some or all of their post-transplant care. Veterans who received Veterans Health Administration-only post-transplant care had the lowest 5-year mortality., (Copyright © 2021 by the American Society of Nephrology.)

Objective: To estimate the feasibility of using measures developed by the Clinical Workgroup of the National Preconception Health and Health Care Initiative to assess women's prepregnancy wellness in a large health care system., Methods: We examined Department of Veterans Affairs' (VA) national administrative data, including inpatient, outpatient, fee-basis, laboratory, pharmacy, and screening data for female veterans aged 18-45 who had at least one pregnancy outcome (ectopic pregnancy, spontaneous abortion, stillbirth, and live birth) during fiscal years 2010-2015 and a VA primary care visit within 1 year before last menstrual period (LMP). LMP was estimated from gestational age at the time of pregnancy outcome, then used as a reference point to assess eight prepregnancy indicators from the Workgroup consensus measures (eg, 3 or 12 months before LMP)., Results: We identified 19,839 pregnancy outcomes from 16,034 female veterans. Most (74.9%) pregnancies ended in live birth; 22.6% resulted in spontaneous abortion or ectopic pregnancy, and 0.5% in stillbirth. More than one third (39.2%) of pregnancies had no documentation of prenatal care within 14 weeks of LMP. Nearly one third (31.2%) of pregnancies occurred in women with obesity. Among pregnancies with a recent relevant screening, 29.2% were positive for smoking and 28.4% for depression. More than half (57.4%) of pregnancies in women with preexisting diabetes did not have documentation of optimal glycemic control. Absence of sexually transmitted infection screening in the year before or within 3 months of LMP was high. Documentation of prenatal folic acid use was also high. Exposure in the same timeframe to six classes of teratogenic medications was low., Conclusion: Despite limitations of administrative data, monitoring measures of prepregnancy wellness can provide benchmarks for improving women's health across health care systems and communities. Areas for intervention to improve female veterans' prepregnancy wellness include healthy weight, optimizing control of diabetes before pregnancy, and improved use and documentation of key prepregnancy health screenings., Competing Interests: Financial Disclosure The authors did not report any potential conflicts of interest., (Copyright © 2021 by the American College of Obstetricians and Gynecologists.

Objectives: Geriatric palliative care approaches support deprescribing of antihypertensives in older nursing home (NH) residents with limited life expectancy and/or advanced dementia (LLE/AD) who are intensely treated for hypertension (HTN), but information on real-world deprescribing patterns in this population is limited. We examined the incidence and factors associated with antihypertensive deprescribing., Design: National, retrospective cohort study., Setting and Participants: Older Veterans with LLE/AD and HTN admitted to VA NHs in fiscal years 2009-2015 with potential overtreatment of HTN at admission, defined as receiving at least 1 antihypertensive class of medications and mean daily systolic blood pressure (SBP) <120 mm Hg., Measures: Deprescribing was defined as subsequent dose reduction or discontinuation of an antihypertensive for ≥7 days. Competing risk models assessed cumulative incidence and factors associated with deprescribing., Results: Within our sample (n = 10,574), cumulative incidence of deprescribing at 30 days was 41%. Veterans with the greatest level of overtreatment (ie, multiple antihypertensives and SBP <100 mm Hg) had an increased likelihood (hazard ratio 1.75, 95% confidence interval 1.59, 1.93) of deprescribing vs those with the lowest level of overtreatment (ie, one antihypertensive and SBP ≥100 to <120 mm Hg). Several markers of poor prognosis (ie, recent weight loss, poor appetite, dehydration, dependence for activities of daily living, pain) and later admission year were associated with increased likelihood of deprescribing, whereas cardiovascular risk factors (ie, diabetes, congestive heart failure, obesity), shortness of breath, and admission source from another NH or home/assisted living setting (vs acute hospital) were associated with decreased likelihood., Conclusions and Implications: Real-world deprescribing patterns of antihypertensives among NH residents with HTN and LLE/AD appear to reflect variation in recommendations for HTN treatment intensity and individualization of patient care in a population with potential overtreatment. Factors facilitating deprescribing included treatment intensity and markers of poor prognosis. Comparative effectiveness and safety studies are needed to guide clinical decisions around deprescribing and HTN management., (Published by Elsevier Inc.)

Background/objectives: Geriatric guidelines recommend against statin use in older adults with limited life expectancy (LLE) or advanced dementia (AD). This study examined resident and facility factors predicting statin discontinuation after nursing home (NH) admission in veterans with LLE/AD taking statins for secondary prevention., Design: Retrospective cohort study of Veterans Affairs (VA) bar code medication administration records, Minimum Data Set (MDS) assessments, and utilization records linked to Medicare claims., Setting: VA NHs, known as community living centers (CLCs)., Participants: Veterans aged 65 and older with coronary artery disease, stroke, or diabetes mellitus, type II, admitted in fiscal years 2009 to 2015, who met criteria for LLE/AD on their admission MDS and received statins in the week after admission (n = 13,110)., Measurements: Residents were followed until statin discontinuation (ie, gap in statin use ≥14 days), death, or censoring due to discharge, day 91 of the stay, or end of the study period. Competing risk models assessed cumulative incidence and predictors of discontinuation, stratified by whether the resident had their end-of-life (EOL) status designated or used hospice at admission., Results: Overall cumulative incidence of statin discontinuation was 31% (95% confidence interval [CI] = 30%-32%) by day 91, and it was markedly higher in those with (52%; 95% CI = 50%-55%) vs without (25%; 95% CI = 24%-26%) EOL designation/hospice. In patients with EOL designation/hospice (n = 2,374), obesity, congestive heart failure, and admission from nonhospital settings predicted decreased likelihood of discontinuation; AD, dependency in activities of daily living, greater number of medications, and geographic region predicted increased likelihood of discontinuation. In patients without EOL designation/hospice (n = 10,736), older age and several specific markers of poor prognosis predicted greater discontinuation, whereas obesity/overweight predicted decreased discontinuation., Conclusion: Most veterans with LLE/AD taking statins for secondary prevention do not discontinue statins following CLC admission. Designating residents as EOL status, hospice use, and individual clinical factors indicating poor prognosis may prompt deprescribing., (Published 2020.

Objective: To identify sociodemographic profiles of patients prescribed high-dose opioids., Design: Cross-sectional cohort study., Setting/patients: Veterans dually-enrolled in Veterans Health Administration and Medicare Part D, with ≥1 opioid pre-scription in 2012., Main Outcome Measures: We identified five patient-level demographic characteristics and 12 community variables re-flective of region, socioeconomic deprivation, safety, and internet connectivity. Our outcome was the proportion of vet-erans receiving >120 morphine milligram equivalents (MME) for ≥90 consecutive days, a Pharmacy Quality Alliance measure of chronic high-dose opioid prescribing. We used classification and regression tree (CART) methods to identify risk of chronic high-dose opioid prescribing for sociodemographic subgroups., Results: Overall, 17,271 (3.3 percent) of 525,716 dually enrolled veterans were prescribed chronic high-dose opioids. CART analyses identified 35 subgroups using four sociodemographic and five community-level measures, with high-dose opioid prescribing ranging from 0.28 percent to 12.1 percent. The subgroup (n = 16,302) with highest frequency of the outcome included veterans who were with disability, age 18-64 years, white or other race, and lived in the Western Census region. The subgroup (n = 14,835) with the lowest frequency of the outcome included veterans who were with-out disability, did not receive Medicare Part D Low Income Subsidy, were >85 years old, and lived in communities within the second and sixth to tenth deciles of community public assistance., Conclusions: Using CART analyses with sociodemographic and community-level variables only, we identified sub-groups of veterans with a 43-fold difference in chronic high-dose opioid prescriptions. Interactions among disability, age, race/ethnicity, and region should be considered when identifying high-risk subgroups in large populations.

Background: Nearly half of all pregnancies in the United States each year are unintended, with the highest rates observed among non-Hispanic black and Hispanic women. Little is known about whether variations in unintended pregnancy and contraceptive use across racial and ethnic groups persist among women veteran Veterans Affairs users who have more universal access than other populations to health care and contraceptive services., Objectives: The objectives of this study were to identify a history of unintended pregnancy and describe patterns of contraceptive use across racial and ethnic groups among women veterans accessing Veterans Affairs primary care., Study Design: Cross-sectional data from a national random sample of women veterans (n = 2302) aged 18-44 years who had accessed Veterans Affairs primary care in the previous 12 month were used to assess a history of unintended pregnancy (pregnancies reported as either unwanted or having occurred too soon). Any contraceptive use at last sex (both prescription and nonprescription methods) and prescription contraceptive use at last sex were assessed in the subset of women (n = 1341) identified as being at risk for unintended pregnancy. Prescription contraceptive methods include long-acting reversible contraceptive methods (intrauterine devices and subdermal implants), hormonal methods (pill, patch, ring, and injection), and female or male sterilization; nonprescription methods include barrier methods (eg, condoms, diaphragm), fertility-awareness methods, and withdrawal. Multivariable logistic regression models were used to examine the relationship between race/ethnicity with unintended pregnancy and contraceptive use at last sex., Results: Overall, 94.4% of women veterans at risk of unintended pregnancy used any method of contraception at last sex. Intrauterine devices (18.9%), female surgical sterilization (16.9%), and birth control pills (15.9%) were the 3 most frequently used methods across the sample. Intrauterine devices were the most frequently used method for Hispanic, non-Hispanic white, and other non-Hispanic women, while female surgical sterilization was the most frequently used method among non-Hispanic black women. In adjusted models, Hispanic women (adjusted odds ratio, 1.60, 95% confidence interval, 1.15-2.21) and non-Hispanic black women (adjusted odds ratio, 1.84, 95% confidence interval, 1.44-2.36) were significantly more likely than non-Hispanic white women to report any history of unintended pregnancy. In the subcohort of 1341 women at risk of unintended pregnancy, there were no significant racial/ethnic differences in use of any contraception at last sex. However, significant differences were observed in the use of prescription methods at last sex. Hispanic women (adjusted odds ratio, 0.51, 95% confidence interval, 0.35-0.75) and non-Hispanic black women (adjusted odds ratio, 0.69, 95% confidence interval, 0.51-0.95) were significantly less likely than non-Hispanic white women to have used prescription contraception at last sex., Conclusion: Significant racial and ethnic differences exist in unintended pregnancy and contraceptive use among women veterans using Veterans Affairs care, suggesting the need for interventions to address potential disparities. Improving access to and delivery of patient-centered reproductive goals assessment and contraceptive counseling that can address knowledge gaps while respectfully considering individual patient preferences is needed to support women veterans' decision making and ensure equitable reproductive health services across Veterans Affairs., (Published by Elsevier Inc.)

Background and Objectives: It is unknown whether iodinated contrast causes kidney parenchymal damage. Biomarkers that are more specific to nephron injury than serum creatinine may provide insight into whether contrast-associated AKI reflects tubular damage. We assessed the association between biomarker changes after contrast angiography with contrast-associated AKI and 90-day major adverse kidney events and death., Design, Setting, Participants, & Measurements: We conducted a longitudinal analysis of participants from the biomarker substudy of the Prevention of Serious Adverse Events following Angiography trial. We measured injury (kidney injury molecule-1, neutrophil gelatinase-associated lipocalin, IL-18) and repair (monocyte chemoattractant protein-1, uromodulin, YKL-40) proteins from plasma and urine samples at baseline and 2-4 hours postangiography. We assessed the associations between absolute changes and relative ratios of biomarkers with contrast-associated AKI and 90-day major adverse kidney events and death., Results: Participants ( n =922) were predominately men (97%) with diabetes (82%). Mean age was 70±8 years, and eGFR was 48±13 ml/min per 1.73 m 2 ; 73 (8%) and 60 (7%) participants experienced contrast-associated AKI and 90-day major adverse kidney events and death, respectively. No postangiography urine biomarkers were associated with contrast-associated AKI. Postangiography plasma kidney injury molecule-1 and IL-18 were significantly higher in participants with contrast-associated AKI compared with those who did not develop contrast-associated AKI: 428 (248, 745) versus 306 (179, 567) mg/dl; P =0.04 and 325 (247, 422) versus 280 (212, 366) mg/dl; P =0.009, respectively. The majority of patients did not experience an increase in urine or plasma biomarkers. Absolute changes in plasma IL-18 were comparable in participants with contrast-associated AKI (-30 [-71, -9] mg/dl) and those without contrast-associated AKI (-27 [-53, -10] mg/dl; P =0.62). Relative ratios of plasma IL-18 were also comparable in participants with contrast-associated AKI (0.91; 0.86, 0.97) and those without contrast-associated AKI (0.91; 0.85, 0.96; P =0.54)., Conclusions: The lack of significant differences in the absolute changes and relative ratios of injury and repair biomarkers by contrast-associated AKI status suggests that the majority of mild contrast-associated AKI cases may be driven by hemodynamic changes at the kidney., (Copyright © 2020 by the American Society of Nephrology.)

Background: We sought to compare associations of contraceptive preferences, beliefs, self-efficacy, and knowledge with use of sterilization versus other methods of contraception. Materials and Methods: This is a secondary analysis of a telephone-based survey of a nationally representative sample of women Veterans not desiring future pregnancy. Contraceptive method used at last sex was categorized as female sterilization, long-acting reversible contraception (LARC), short-acting methods, or nonprescription methods/no method. Multinomial regression models were performed to compare the association between independent variables (contraceptive preferences, beliefs, self-efficacy, and knowledge) and use of sterilization versus other contraceptive methods. Results: Six hundred twelve women Veterans aged 18-44 years who were sexually active with men, had no history of hysterectomy or infertility, did not desire future pregnancy, and were not using male sterilization as their method of contraception were surveyed. A total of 208 women Veterans reported using female sterilization (34.0%). While method effectiveness was rated as extremely important by the majority of participants, there was no association between perceiving method effectiveness as extremely important and method selected in adjusted multinomial models. Women Veterans were more likely to use sterilization compared to hormonal methods of contraception if they reported that lack of hormones was an extremely important contraceptive method characteristic (aRRR 3.69, 95% CI 1.94-7.03). Women Veterans who strongly agreed with the belief that birth control decisions are mainly a woman's responsibility were less likely to use sterilization compared to LARC (aRRR 0.54, 95% CI 0.29-0.98). Conclusion: Associations between contraceptive preferences, beliefs, self-efficacy, and knowledge and use of sterilization in a population of women Veterans not desiring future pregnancy are complex, and decisions may not solely be driven by desire to select a highly effective method.

Background: Women veterans who use the Veterans Affairs Healthcare System theoretically have access to the full range of contraceptive methods. This study explores match between currently used and self-reported "ideal" methods as a potential marker of contraceptive access and preference matching., Methods: This mixed methods study uses data from a nationally representative survey of reproductive-aged women veterans who use the Veterans Affairs Healthcare System for primary care, including 979 participants at risk of unintended pregnancy. Women reported all contraceptive methods used in the past month and were asked, "If you could choose any method of contraception or birth control to prevent pregnancy, what would be your ideal choice?" and selected a single "ideal" method. If applicable, participants were additionally asked, "Why aren't you currently using this method of contraception?" We used adjusted logistic regression to identify patient-, provider-, and system-level factors associated with ideal-current method match. We qualitatively analyzed open-ended responses about reasons for ideal method nonuse., Results: Overall, 58% were currently using their ideal method; match was greatest among women selecting an IUD as ideal (73%). Non-White race/ethnicity (adjusted odds ratio, 0.68; 95% confidence interval, 0.52-0.89) and mental illness (adjusted odds ratio, 0.69; 95% confidence interval, 0.52-0.92) were negatively associated with ideal-current match in adjusted analyses; the presence of a gynecologist at the primary care site was associated with an increased odds of match (adjusted odds ratio, 1.35; 95% confidence interval, 1.03-1.75). Modifiable barriers to ideal method use were cited by 23% of women, including access issues, cost concerns, and provider-level barriers; 79% of responses included nonmodifiable reasons for mismatch including relationship factors and pregnancy plans incongruent with ideal method use, suggesting limitations of our measure based on differential interpretation of the word "ideal.", Conclusions: Many women veterans are not currently using the contraceptive method they consider ideal. Results emphasize the complexity of contraceptive method selection and of measuring contraceptive preference matching., (Copyright © 2020 Jacobs Institute of Women's Health. All rights reserved.)

Background: In 2018, the Department of Veterans Affairs (VA) issued Notice 2018-08 requiring facilities to complete "case reviews" for Veterans identified in the Stratification Tool for Opioid Risk Mitigation (STORM) dashboard as high risk for adverse outcomes among patients prescribed opioids. Half of the facilities were randomly assigned to a Notice version including additional oversight. We evaluated implementation strategies used, whether strategies differed by randomization arm, and which strategies were associated with case review completion rates., Methods: Facility points of contact completed a survey assessing their facility's use of 68 implementation strategies based on the Expert Recommendations for Implementing Change taxonomy. We collected respondent demographic information, facility-level characteristics, and case review completion rates (percentage of high-risk patients who received a case review). We used Kruskal-Wallis tests and negative binomial regression to assess strategy use and factors associated with case reviews., Results: Contacts at 89 of 140 facilities completed the survey (64%) and reported using a median of 23 (IQR 16-31) strategies. The median case review completion rate was 71% (IQR 48-95%). Neither the number or types of strategies nor completion rates differed by randomization arm. The most common strategies were using the STORM dashboard (97%), working with local opinion leaders (80%), and recruiting local partners (80%). Characteristics associated with case review completion rates included respondents being ≤ 35 years old (incidence rate ratio, IRR 1.35, 95% CI 1.09-1.67) and having < 5 years in their primary role (IRR 1.23; 95% CI 1.01-1.51), and facilities having more prior academic detailing around pain and opioid safety (IRR 1.40, 95% CI 1.12-1.75). Controlling for these characteristics, implementation strategies associated with higher completion rates included (1) monitoring and adjusting practices (adjusted IRR (AIRR) 1.40, 95% CI 1.11-1.77), (2) identifying adaptations while maintaining core components (AIRR 1.28, 95% CI 1.03-1.60), (3) conducting initial training (AIRR 1.16, 95% CI 1.02-1.50), and (4) regularly sharing lessons learned (AIRR 1.32, 95% CI 1.09-1.59)., Conclusions: In this national evaluation of strategies used to implement case reviews of patients at high risk of opioid-related adverse events, point of contact age and tenure in the current role, prior pain-related academic detailing at the facility, and four specific implementation strategies were associated with case review completion rates, while randomization to additional centralized oversight was not., Trial Registration: This project is registered at the ISRCTN Registry with number ISRCTN16012111. The trial was first registered on May 3, 2017.

Background: While patients with substance use disorders (SUDs) are thought to encounter poor primary care experiences, the perspectives of patients with opioid use disorder (OUD), specifically, are unknown. This study compares the primary care experiences of patients with OUD, other SUDs and no SUD in the Veterans Health Administration., Methods: The sample included Veterans who responded to the national Patient-Centered Medical Home Survey of Healthcare Experiences of Patients, 2013-2015. Respondents included 3554 patients with OUD, 36,175 with other SUDs, and 756,386 with no SUD; 742 OUD-diagnosed patients received buprenorphine. Multivariable multinomial logistic regressions estimated differences in the probability of reporting positive and negative experiences (0-100 scale) for patients with OUD, compared to patients with other SUDs and no SUD, and for OUD-diagnosed patients treated versus not treated with buprenorphine., Results: Of all domains, patients with OUD reported the least positive experiences with access (31%) and medication decision-making (35%), and the most negative experiences with self-management support (35%) and provider communication (23%). Compared to the other groups, patients diagnosed with OUD reported fewer positive and/or more negative experiences with access, communication, office staff, provider ratings, comprehensiveness, care coordination, and self-management support (adjusted risk differences[aRDs] range from |2.9| to |7.0|). Among OUD-diagnosed patients, buprenorphine was associated with more positive experiences with comprehensiveness (aRD = 8.3) and self-management support (aRD = 7.1), and less negative experiences with care coordination (aRD = -4.9) and medication shared decision-making (aRD = -5.4)., Conclusions: In a national sample, patients diagnosed with OUD encounter less positive and more negative experiences than other primary care patients, including those with other SUDs. Buprenorphine treatment relates positively to experiences with care comprehensiveness, medication decisions, and care coordination. As stakeholders encourage more primary care providers to manage OUD, it will be important for healthcare systems to attend to patient access and experiences with care in these settings., Competing Interests: Declaration of competing interest Dr. Stefan G.

Background: Experiences of discrimination are associated with poor health behaviors and outcomes. Understanding discrimination in health care informs interventions to improve health care experiences., Objective: Describe the prevalence of, and variables associated with, perceived gender-based discrimination in the Veterans Affairs (VA) Healthcare System among women Veterans., Design: A cross-sectional, telephone-based survey of a random national sample of young female Veterans., Participants: Female VA primary care patients aged 18-45 years., Main Measures: The primary outcome was perceived gender-based discrimination in VA health care. Logistic and linear regression models were used to determine associations between any perceived discrimination and cumulative perceived discrimination with patient and health service characteristics., Key Results: Among 2294 women Veterans, 33.7% perceived gender-based discrimination in VA. Perceiving gender-based discrimination was associated with medical illness [adjusted odds ratio (aOR)=1.67, 95% confidence interval (CI)=1.34, 2.08], mental illness (aOR=2.06, 95% CI=1.57, 2.69), and military sexual trauma (aOR=2.65, 95% CI=2.11, 3.32). Receiving most health care from the same VA provider (aOR=0.73, 95% CI=0.57, 0.94) and receiving care at a VA site with a women's health clinic (aOR=0.76, 95% CI=0.61, 0.95) were associated with reduced odds of any perceived gender-based discrimination. Among those who perceived gender-based discrimination (n=733), perceived discrimination scores were higher among women with increased age, medical illness, or history of military sexual trauma and lower among those who saw the same VA provider for most medical care., Conclusions: One third of women Veterans perceived gender-based discrimination in VA. Obtaining most medical care from the same VA provider and having a women's health clinic at one's VA were associated with less perceived discrimination.

Background: After non-fatal opioid overdoses, opioid prescribing patterns are often unchanged and the use of medications for opioid use disorder (MOUDs) remains low. Whether such prescribing differs by race/ethnicity remains unknown., Objective: To assess the association of race/ethnicity with the prescribing of opioids and MOUDs after a non-fatal opioid overdose., Design: Retrospective cohort study., Participants: Patients prescribed ≥ 1 opioid from July 1, 2010, to September 30, 2015, with a non-fatal opioid overdose in the Veterans Health Administration (VA)., Main Measures: Primary outcomes were the proportion of patients prescribed: (1) any opioid during the 30 days before and after overdose and (2) MOUDs within 30 days after overdose by race and ethnicity. We conducted difference-in-difference analyses using multivariable regression to assess whether the change in opioid prescribing from before to after overdose differed by race/ethnicity. We also used multivariable regression to test whether MOUD prescribing after overdose differed by race/ethnicity., Key Results: Among 16,210 patients with a non-fatal opioid overdose (81.2% were white, 14.3% black, and 4.5% Hispanic), 10,745 (66.3%) patients received an opioid prescription (67.1% white, 61.7% black, and 65.9% Hispanic; p < 0.01) before overdose. After overdose, the frequency of receiving opioids was reduced by 18.3, 16.4, and 20.6 percentage points in whites, blacks, and Hispanics, respectively, with no significant difference-in-difference in opioid prescribing by race/ethnicity (p = 0.23). After overdose, 526 (3.2%) patients received MOUDs (2.9% white, 4.6% black, and 5.5% Hispanic; p < 0.01). Blacks (adjusted OR (aOR) 1.6; 95% CI 1.2, 1.9) and Hispanics (aOR 1.8; 95% CI 1.2, 2.6) had significantly larger odds of receiving MOUDs than white patients., Conclusions: In a national cohort of patients with non-fatal opioid overdose in VA, there were no racial/ethnic differences in changes in opioid prescribing after overdose. Although blacks and Hispanics were more likely than white patients to receive MOUDs in the 30 days after overdose, less than 4% of all groups received such therapy.

Objectives: Many older adults with limited life expectancy and/or advanced dementia (LLE/AD) are potentially overtreated for diabetes and may benefit from deintensification. Our aim was to examine the incidence and predictors of diabetes medication deintensification in older Veterans with LLE/AD who were potentially overtreated at admission to Veterans Affairs (VA) nursing homes (community living centers [CLCs])., Design: Retrospective cohort study using linked VA and Medicare clinical/administrative data and Minimum Data Set assessments., Setting: VA CLCs., Participants: A total of 6960 Veterans with diabetes and LLE/AD admitted to VA CLCs in fiscal years 2009 to 2015 with hemoglobin (Hb)A1c measured within 90 days of admission., Measurements: We evaluated treatment deintensification (discontinuation or dose reduction for a consecutive 7-day period) among residents who were potentially overtreated (HbA1c ≤7.5% and receiving hypoglycemic medications). Competing risk models assessed 90-day cumulative incidence of deintensification., Results: More than 40% (n = 3056) of Veteran CLC residents with diabetes were potentially overtreated. The cumulative incidence of deintensification at 90 days was 45.5%. Higher baseline HbA1c values were associated with a lower likelihood of deintensification (e.g., HbA1c 7.0-7.5% vs <6.0%; adjusted risk ratio [aRR] = .57; 95% confidence interval [CI] = .50-.66). Compared with non-sulfonylurea oral agents (e.g., metformin), other treatment regimens were more likely to be deintensified (aRR = 1.31-1.88), except for basal insulin (aRR = .59; 95% CI = .52-.66). The only resident factor associated with increased likelihood of deintensification was documented end-of-life status (aRR = 1.12; 95% CI = 1.01-1.25). Admission from home/assisted living (aRR = .85; 95% CI = .75-.96), obesity (aRR = .88; 95% CI = .78-.99), and peripheral vascular disease (aRR = .90; 95% CI = .81-.99) were associated with decreased likelihood of deintensification., Conclusion: Deintensification of treatment regimens occurred in less than one-half of potentially overtreated Veterans and was more strongly associated with low HbA1c values and use of medications with high risk for hypoglycemia, rather than other resident characteristics.

Objectives: Continuation of aspirin for secondary prevention in persons with limited life expectancy (LLE) is controversial. We sought to determine the incidence and predictors of aspirin discontinuation in veterans with LLE and/or advanced dementia (LLE/AD) who were taking aspirin for secondary prevention at nursing home admission, stratified by whether their limited prognosis (LP) was explicitly documented at admission., Design: Retrospective cohort study using linked Veterans Affairs (VA) and Medicare clinical/administrative data and Minimum Data Set resident assessments., Setting: All VA nursing homes (referred to as community living centers [CLCs]) in the United States., Participants: Older (≥65 y) CLC residents with LLE/AD, admitted for 7 days or longer in fiscal years 2009 to 2015, who had a history of coronary artery disease and/or stroke/transient ischemic attack, and used aspirin within the first week of CLC admission (n = 13 844)., Measurements: The primary dependent variable was aspirin discontinuation within the first 90 days after CLC admission, defined as 14 consecutive days of no aspirin receipt. Independent variables included an indicator for explicit documentation of LP, sociodemographics, environment of care characteristics, cardiovascular risk factors, bleeding risk factors, individual markers of poor prognosis (eg, cancer, weight loss), and facility characteristics. Fine and Gray subdistribution hazard models with death as a competing risk were used to assess predictors of discontinuation., Results: Cumulative incidence of aspirin discontinuation was 27% (95% confidence interval [CI] = 26%-28%) in the full sample, 34% (95% CI = 33%-36%) in residents with explicit documentation of LP, and 24% (95% CI = 23%-25%) in residents with no such documentation. The associations of independent variables with aspirin discontinuation differed in residents with vs without explicit LP documentation at admission., Conclusion: Just over one-quarter of patients discontinued aspirin, possibly reflecting the unclear role of aspirin in end of life among prescribers. Future research should compare outcomes of aspirin deprescribing in this population. J Am Geriatr Soc 68:725-735, 2020., (Published 2020.

Introduction: Racial/ethnic disparities exist in the Veterans Health Administration (VHA), despite financial barriers to care being largely mitigated and Veterans Administration's (VA) organizational commitment to health equity. Accurately identifying minority veterans is critical to monitoring progress toward equity as the VHA treats an increasingly racially and ethnically diverse veteran population. Although the VHA's completeness of race and ethnicity data is generally better than its public sector and private counterparts, the accuracy of the race and ethnicity in the various databases available to VHA is variable, as is the accuracy in identifying specific minority groups. The purpose of this article was to develop an algorithm for constructing race and ethnicity variables from data sources available to VHA researchers, to present demographic differences cross the data sources, and to apply the algorithm to one study year., Materials and Methods: We used existing VHA survey data from the Survey of Healthcare Experiences of Patients (SHEP) and three commonly used administrative databases from 2003 to 2015: the VA Corporate Data Warehouse (CDW), VA Defense Identity Repository (VADIR), and Medicare. Using measures of agreement such as sensitivity, specificity, positive and negative predictive values, and Cohen kappa, we compared self-reported race and ethnicity from the SHEP and each of the other data sources. Based on these results, we propose an algorithm for combining data on race and ethnicity from these datasets. We included VHA patients who completed a SHEP and had race/ethnicity recorded in CDW, VADIR, and/or Medicare., Results: Agreement between SHEP and other sources was high for Whites and Blacks and substantially lower for other minority groups. The CDW demonstrated better agreement than VADIR or Medicare., Conclusions: We developed an algorithm of data source precedence in the VHA that improves the accuracy of the identification of historically under-identified minorities: (1) SHEP, (2) CDW, (3) Department of Defense's VADIR, and (4) Medicare., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2019.

Rationale & Objective: The PRESERVE trial used a 2 × 2 factorial design to compare intravenous saline solution with intravenous sodium bicarbonate solution and oral N-acetylcysteine with placebo for the prevention of 90-day major adverse kidney events and death (MAKE-D) and contrast-associated acute kidney injury (CA-AKI) among patients with chronic kidney disease undergoing angiography. In this ancillary study, we evaluated the predictive capacities of preangiography injury and repair proteins in urine and plasma for MAKE-D, CA-AKI, and their impact on trial design., Study Design: Longitudinal analysis., Setting & Participants: A subset of participants from the PRESERVE trial., Exposures: Injury (KIM-1, NGAL, and IL-18) and repair (MCP-1, UMOD, and YKL-40) proteins in urine and plasma 1 to 2 hours preangiography., Outcomes: MAKE-D and CA-AKI., Analytical Approach: We analyzed the associations of preangiography biomarkers with MAKE-D and with CA-AKI. We evaluated whether the biomarker levels could enrich the MAKE-D event rate and improve future clinical trial efficiency through an online biomarker prognostic enrichment tool available at prognosticenrichment.com., Results: We measured plasma biomarkers in 916 participants and urine biomarkers in 797 participants. After adjusting for urinary albumin-creatinine ratio and baseline estimated glomerular filtration rate, preangiography levels of 4 plasma (KIM-1, NGAL, UMOD, and YKL-40) and 3 urine (NGAL, IL-18, and YKL-40) biomarkers were associated with MAKE-D. Only plasma KIM-1 level was significantly associated with CA-AKI after adjustment. Biomarker levels provided modest discriminatory capacity for MAKE-D. Screening patients using the 50th percentile of preangiography plasma KIM-1 or YKL-40 levels would have reduced the required sample size by 30% (∼2,000 participants)., Limitations: Evaluation of prognostic enrichment does not account for changing trial costs, time needed to screen patients, or loss to follow-up. Most participants were male, limiting the generalizability of our findings., Conclusions: Preangiography levels of injury and repair biomarkers modestly predict the development of MAKE-D and can be used to improve the efficiency of future CA-AKI trials., (Copyright © 2019 National Kidney Foundation, Inc.
