For almost 2 decades, equations that use serum creatinine, age, sex, and race to estimate glomerular filtration rate (GFR) have included "race" as Black or non-Black. Given considerable evidence of disparities in health and health care delivery in African American communities, some regard keeping a race term in GFR equations as a practice that differentially influences access to care and kidney transplantation. Others assert that race captures important non-GFR determinants of serum creatinine and its removal from the calculation may perpetuate other disparities. The National Kidney Foundation (NKF) and American Society of Nephrology (ASN) established a task force in 2020 to reassess the inclusion of race in the estimation of GFR in the United States and its implications for diagnosis and subsequent management of patients with, or at risk for, kidney diseases. This interim report details the process, initial assessment of evidence, and values defined regarding the use of race to estimate GFR. We organized activities in phases: (1) clarify the problem and examine evidence, (2) evaluate different approaches to address use of race in GFR estimation, and (3) make recommendations. In phase 1, we constructed statements about the evidence and defined values regarding equity and disparities; race and racism; GFR measurement, estimation, and equation performance; laboratory standardization; and patient perspectives. We also identified several approaches to estimate GFR and a set of attributes to evaluate these approaches. Building on evidence and values, the attributes of alternative approaches to estimate GFR will be evaluated in the next phases and recommendations will be made.

Background: The COVID-19 pandemic has highlighted that bereavement care is under-recognized with few hospitals offering universal bereavement services. Methods: One hundred sixty-nine bereaved individuals, whose loved ones died at our hospital during 2021 and 2022, completed a survey about their experience with the bereavement program. Results: Of respondents who recalled receiving bereavement outreach, 79% rated speaking to a team member soon after the death as having a positive impact on their bereavement, and 75% rated receiving a condolence call or note from the team positively. Feedback also identified opportunities for improvements in care: (1) importance of compassionate communication and connection with family members after a death; (2) more flexible hospital visitation policies; and (3) additional support for families during the end-of-life (EOL) period. Conclusions: The findings demonstrated that a hospital-based bereavement program can positively impact an individual's bereavement experience with a formal letter of condolence, psychoeducation information, and direct outreach from team members soon after death, being positively evaluated.

Background Older patients with brain metastases (BrM) commonly experience symptoms that prompt acute medical evaluation. We characterized emergency department (ED) visits and inpatient hospitalizations in this population. Methods We identified 17 789 and 361 Medicare enrollees diagnosed with BrM using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database (2010-2016) and an institutional database (2007-2016), respectively. Predictors of ED visits and hospitalizations were assessed using Poisson regression. Results The institutional cohort averaged 3.3 ED visits/1.9 hospitalizations per person-year, with intracranial disease being the most common reason for presentation/admission. SEER-Medicare patients averaged 2.8 ED visits/2.0 hospitalizations per person-year. For patients with synchronous BrM (N = 7834), adjusted risk factors for ED utilization and hospitalization, respectively, included: male sex (rate ratio [RR] = 1.15 [95% CI = 1.09-1.22], P <.001; RR = 1.21 [95% CI = 1.13-1.29], P <.001); African American vs white race (RR = 1.30 [95% CI = 1.18-1.42], P <.001; RR = 1.25 [95% CI = 1.13-1.39], P <.001); unmarried status (RR = 1.07 [95% CI = 1.01-1.14], P =.02; RR = 1.09 [95% CI = 1.02-1.17], P =.01); Charlson comorbidity score >2 (RR = 1.27 [95% CI = 1.17-1.37], P <.001; RR = 1.36 [95% CI = 1.24-1.49], P <.001); and receipt of non-stereotactic vs stereotactic radiation (RR = 1.44 [95% CI = 1.34-1.55, P <.001; RR = 1.49 [95% CI = 1.37-1.62, P <.001). For patients with metachronous BrM (N = 9955), ED visits and hospitalizations were more common after vs before BrM diagnosis (2.6 vs 1.2 ED visits per person-year; 1.8 vs 0.9 hospitalizations per person-year, respectively; RR = 2.24 [95% CI = 2.15-2.33], P <.001; RR = 2.06 [95% CI = 1.98-2.15], P <.001, respectively). Conclusions Older patients with BrM commonly receive hospital-level care secondary to intracranial disease, especially in select subpopulations. Enhanced care coordination, closer outpatient follow-up, and patient navigator programs seem warranted for this population. [ABSTRACT FROM AUTHOR]

Background: New inpatient virtual care models have proliferated in response to the challenges presented by the COVID-19 pandemic, however, few of these programs have yet been evaluated for acceptability and feasibility. We present the results of a survey of feasibility and provider experience with the Virtual Team Rounding Program (VTRP), a quality improvement project developed and rapidly scaled at Brigham and Women's Hospital in Boston, MA, in response to the surge of COVID-19 patients in the spring of 2020.Methods: We surveyed 777 inpatient providers and 41 providers who served as "virtual rounders" regarding their experience with the program. Inpatient providers were asked about their overall satisfaction with the program, whether they the program saved them time, and if so, how much, and their interest in working with a similar program in the future. Providers who had worked as virtual rounders were asked about their overall satisfaction with the program, the overall difficulty of the work, and their interest in participating in a similar program in the future.Results: We find that among both groups the program was well-received, with 72.5% of inpatient providers and 85.7% of virtual rounders reporting they were "satisfied" or "very satisfied" with their experience with the program. Among inpatient providers who worked with the program, two-thirds reported the program saved them time on a daily basis. Inpatient respondents who had worked with virtual rounders were more likely to say that they would be interested in working with the VTRP in the future compared with respondents who never worked with a virtual rounder (75.3% vs 52.5%, p < 0.001).Conclusion: As the pandemic continues, rapidly implementing and studying virtual care delivery programs is crucial for hospitals and health systems. We demonstrate the feasibility and acceptability of a "virtual rounding" program assisting inpatient providers. Future work should examine the impact of these programs on patient outcomes.

Introduction: Chronic kidney disease (CKD) patients are vulnerable to hepatitis B, and immunization prior to end stage kidney disease is recommended to optimize seroconversion. Our institution undertook a process improvement approach to increase hepatitis B vaccination in stage 4 and 5 CKD patients. Methods: Four strategies were utilized such as: (1) Electronic health record (EHR)-based CKD registry to identify patients, (2) EHR-based physician/nurse reminders, (3) a co-located nurse appointment for vaccine administration, and (4) information sharing and provider awareness effort. The CKD registry was utilized to identify patients with stage 4 or 5 CKD, with at least two clinic visits in the prior 2 years, who had not received the hepatitis B vaccine or did not have serologic evidence of immunity. Target monthly vaccination rate was set at 75%, based on clinic leadership, nephrologist, and nurse consensus. Results: A total of 239 patients were included in the study period, from November 2018 to January 2019 (observation period) and from February 2019 to September 2019 (intervention period). Monthly vaccination rate improved from 48% in November 2018 to the target rate of 75% by the end of the intervention (August and September 2019). There was a statistically significant increase from the rate of vaccination at a unique patient level in the first month of the baseline period, compared to the last month of the intervention period (51 vs. 75% p = 0.03). Conclusions: Utilizing a nurse-led approach to hepatitis B vaccination, coupled with EHR-based tools, along with continuous monitoring of performance, helped to improve hepatitis B vaccination among CKD stage 4 and 5 patients.

Background: Electronic consultations (e-consults) can facilitate patient access to specialists, minimize travel, and reduce unnecessary in-person visits. However, metrics to enable study of e-consults and their effect on processes and patient care are lacking.Objective: To assess novel metrics of e-consult appropriateness and utility.Design: Retrospective cohort study.Setting: Primary and specialty care practices at 2 large academic and 2 community hospitals of an integrated health system.Participants: Patients with e-consult requests to 5 specialties-hematology, infectious disease, dermatology, rheumatology, and psychiatry-between October 2017 and November 2018.Measurements: The appropriateness of e-consult inquiries was assessed by review of medical records and defined as meeting the following 4 criteria: not answerable by reviewing evidence-based summary sources ("point-of-care resource test"), not merely requesting logistic information, having appropriate clinical urgency, and having appropriate patient complexity. Interrater agreement in assessments of e-consult appropriateness was assessed by the κ statistic. Utility of e-consults was assessed by the rate of avoided visits (AVs), defined by the absence of an in-person visit to the same specialty within 120 days.Results: Overall, 6512 eligible e-consults were made by 1096 referring providers to 121 specialist consultants. Inquiries were characterized as diagnostic, therapeutic, for provider education, or at the request of the patient. Most consultations were answered within 1 day, with variation across specialties (73.1% for psychiatry to 87.8% for infectious disease). Overall, 70.2% of e-consults met all 4 criteria for appropriateness; the frequency of unmet criteria varied among specialties. Raters agreed on the appropriateness of 94% of e-consults (κ = 0.57 [95% CI, 0.36 to 0.79]), indicating moderate agreement. The overall rate of AVs across the 5 specialties was 81.2%; the highest rate was in psychiatry (92.6%) and the lowest in dermatology (61.9%).Limitation: Generalizability is unknown outside a single integrated health system, where requesting and consulting providers share a common electronic health record.Conclusion: Novel metrics to assess the appropriateness and utility of e-consults provide meaningful insight into practice, provide a rubric for comparison in future studies in additional settings, and suggest areas to improve resource use and patient care.Primary Funding Source: None.

Importance Death due to preventable medical error is a leading cause of death, with varying estimates of preventable death rates (14%-56% of total deaths based on national extrapolated estimates, 3%-11% based on single-centre estimates). Yet, how best to reduce preventable mortality in hospitals remains unknown. Objective In this article, we detail lessons learnt from implementing a hospital-wide, automated, real-time, electronic mortality reporting system that relies on the opinions of front-line clinicians to identify opportunities for improvement. We also summarise data obtained regarding possible preventability, systems issues identified and addressed, and challenges with implementation. We outline our process of survey, evaluation, escalation and tracking of opportunities identified through the review process. Methods We aggregated and analysed 7 years of review data regarding deaths, review responses categorised by ratings of possible preventability and inter-rater reliability of possible preventability. A qualitative analysis of reviews was performed to identify care delivery opportunities and institutional response. Results Over the course of 7 years, 7856 inpatient deaths occurred, and 91% had at least one review completed. 5.2% were rated by front-line clinicians as potentially being preventable (likely or possibly), and this rate was consistent over time. However, there was only slight inter-rater agreement regarding potential preventability (Cohen's kappa=0.185). Nevertheless, several major systems-level opportunities were identified that facilitated care delivery improvements, such as communication challenges, need for improved end-of-life care and interhospital transfer safety. Conclusions Through implementation, we found that a hospital-wide mortality review process that elicits feedback from front-line providers is feasible, and provides valuable insights regarding potential preventable mortality and prioritising actionable opportunities for care delivery improvements.

Renal replacement therapy (RRT) in the setting of acute kidney injury (AKI) is generally provided by either tunneled or nontunneled dialysis catheters (TDCs or NTDCs), used immediately after insertion. Current consensus guidelines suggest using NTDCs rather than TDCs for vascular access in AKI primarily for logistical reasons, including ease of insertion and timeliness. However, there is increasing evidence that, compared to NTDCs, TDCs are associated with fewer complications (mechanical and infectious) and better dialysis delivery. Nevertheless, this evidence must be balanced by the feasibility and practicality of implementing a "TDC-first approach." In this paper, we assess the current evidence base for vascular access choice for AKI requiring RRT. We make the case for increased use of TDCs as first-line vascular access given growing observational evidence for improved patient outcomes; including decreased risk of infection and thrombosis, increased blood flow rates and decreased treatment interruptions, compared to NDTCs. We advocate for further research to test the feasibility and outcomes associated with a TDC-first approach to AKI-RRT access. A TDC-first approach has the potential to improve RRT clinical outcomes and reduce resource utilization and cost. [ABSTRACT FROM AUTHOR]

There is wide variation in clinical practice regarding timing of discontinuation of renal replacement therapy (RRT) in patients with acute kidney injury (AKI). Prolonged, unnecessary RRT treatment can contribute to length of stay, overall hospital costs, and risk of complications associated with RRT. In addition, prolonged RRT can paradoxically lengthen the time for which the patient remains dialysis-dependent. Well-designed, randomized clinical trials have utilized varied discontinuation criteria specifically related to urine output and creatinine clearance, which impedes the comparison of outcomes from such studies. Other observational studies have attempted to assess the sensitivity and specificity of various criteria for discontinuation of RRT. Whether diuretics influence renal recovery has not been fully elucidated as well. In this article, we propose a starting framework for RRT discontinuation criteria to guide clinicians and clinical researchers. We emphasize the importance of frequent clinical assessment while considering discontinuation of RRT for AKI patients with a creatinine clearance >15 mL/min on a timed urine collection and/or a urine output >400 mL/24 h without diuretics, or >2000 mL/24 h with diuretics. We also discuss newer biomarkers, methods of GFR estimation, and imaging techniques that may play a greater role in the future. Clinical trials objectively comparing the success of RRT discontinuation criteria will be required to provide high-quality evidence for our proposed guidelines. [ABSTRACT FROM AUTHOR]

Background: Acute kidney injury requiring renal replacement therapy (AKI-RRT) is associated with high morbidity, mortality and resource utilization. The type of vascular access placed for AKI-RRT is an important decision, for which there is a lack of evidence-based guidelines.Methods: We conducted a prospective cohort study over a 16-month period with 154 patients initiated on AKI-RRT via either a non-tunneled dialysis catheter (NTDC) or a tunneled dialysis catheter (TDC) at an academic hospital. We compared differences in renal replacement delivery and mechanical and infectious outcomes between NTDCs and TDCs.Results: Patients who received TDCs had significantly better RRT delivery, both with continuous venovenous hemofiltration (CVVH) and intermittent hemodialysis (IHD), compared to patients who received NTDCs; these findings were confirmed after multivariable adjustment for AKI-specific disease severity score, history of chronic kidney disease, renal consult team, and AKI cause. In CVVH and IHD, the median venous and arterial blood flow pressures were significantly higher with TDCs compared to NTDCs (p < 0.001). Additionally for CVVH, the median number of interruptions per catheter was higher with NTDCs compared to TDCs (Rate Ratio (RR) 2.7; p < 0.001), and for IHD, a higher median blood flow was seen with TDCs (p < 0.001). There were a significantly higher number of mechanical complications with NTDCs (RR 13.6 p = 0.001). No significant difference was observed between TDCs and NTDCs for positive blood cultures per catheter.Conclusions: Compared to NTDCs, TDCs for patients with AKI-RRT had improved RRT delivery and fewer mechanical complications. Initial TDC placement for AKI-RRT should be considered when not clinically contraindicated given the potential for improved RRT delivery and outcomes. [ABSTRACT FROM AUTHOR]

Aim No evidence-based approach to the evaluation of CKD has been established. We sought to identify clinical criteria to guide a rational diagnostic approach for the initial evaluation of CKD. Methods We conducted a retrospective cohort study of 1487 patients presenting for initial evaluation of CKD over 3 years (1/2010-1/2013) to academic nephrology clinics. We utilized the electronic medical record to determine tests ordered, abnormal results and testing that affected diagnosis and/or management. Diagnostic and management yield of testing was defined as the percentage of tests that affected diagnosis and/or management. High yield for a given test was defined as an increased likelihood of the test affecting diagnosis and/or management. Results We identified clinical criteria predictive of high yield for paraprotein-related testing (one of the following: history of monoclonal disease, high risk of CKD progression, hypercalcemia or haemoglobin < 10.6), and clinical criteria predictive of high yield for glomerulonephritis testing (one of the following: abnormal urine sediment, 3+ or greater hematuria or proteinuria > 500 mg/gm). A prior history of hydronephrosis and renal artery stenosis was predictive of high yield of abnormal renal ultrasound. Higher yield of testing was associated with higher risk progression categories for ANA, SPEP, urine sediment, calcium, PTH, haemoglobin, iron and ferritin. We estimate that initial CKD evaluation costs range from $28 to $109 million/year in US-Medicare expenditure. Conclusion Numerous tests without significant clinical utility are obtained in initial CKD evaluation. Identifying criteria that can guide diagnostic testing may lead to a more informed and cost-effective approach to evaluation. [ABSTRACT FROM AUTHOR]

Background: The patterns, performance characteristics, and yield of diagnostic tests ordered for the evaluation of acute kidney injury (AKI) have not been rigorously evaluated.Methods: We characterized the frequency of AKI diagnostic testing for urine, blood, radiology, and pathology tests in all adult inpatients who were admitted with or developed AKI (N = 4903 patients with 5731 AKI episodes) during a single calendar year. We assessed the frequency of abnormal test results overall and by AKI stage. We manually reviewed electronic medical records to evaluate the diagnostic yield of selected urine, blood, and radiology tests. Diagnostic yield of urine and blood tests was determined based on whether an abnormal test affected AKI diagnosis or management, whereas diagnostic yield of radiology tests was based on whether an abnormal test resulted in a procedural intervention. In sensitivity analyses we also evaluated appropriateness of testing using prespecified criteria.Results: Frequency of testing increased with higher AKI stage for nearly all diagnostic tests, whereas frequency of detecting an abnormal result increased for some, but not all, tests. Frequency of detecting an abnormal result was highly variable across tests, ranging from 0 % for anti-glomerular basement membrane testing to 71 % for urine protein testing. Many of the tests evaluated had low diagnostic yield. In particular, selected urine and blood tests were unlikely to impact AKI diagnosis or management, whereas radiology tests had greater clinical utility.Conclusions: In patients with AKI, many of the diagnostic tests performed, even when positive or abnormal, may have limited clinical utility.

Hospitals in the United States are assessed and ranked by several agencies and services, including U.S. News & World Report. Frequently, though, the key hospital throughput metric of inpatient boarding time in the emergency department (ED) is not considered when ranking hospitals. As a result, there is a discordance in which highly ranking hospitals may be poor performers in boarding of patients, a practice with known adverse safety effects. This article outlines the rationale for considering ED boarding in hospital ranking and quality assessments. [ABSTRACT FROM AUTHOR]

The article presents a study which examines the association between the poverty rate and the risk of bloodstream infections among critically ill patients in Boston, Massachusetts. It is inferred that 2,435 of 14,657 patients receiving critical care had bloodstream infections. According to the study, the risk of bloodstream infections is associated with increased neighborhood poverty rate.

OBJECTIVES: The study examined a commercial accountable care organization (ACO) population and then assessed the impact of an integrated care management program on medical spending and clinical event rates. STUDY DESIGN: Retrospective cohort study of high-risk individuals (n = 487) in a population of 365,413 individuals aged 18 to 64 years within the Mass General Brigham health system who were part of commercial ACO contracts with 3 large insurers between 2015 and 2019. METHODS: Using medical spending claims and other enrollment data, the study assessed the demographic and clinical characteristics, medical spending, and clinical event rates of patients in the ACO and its high-risk care management program. The study then examined the impact of the program using a staggered difference-in-difference design with individual-level fixed effects and compared outcomes of those who had entered the program with those of similar patients who had not entered. RESULTS: The commercially insured ACO population was healthy on average but included several hundred high-risk patients (n = 487). After adjustment, patients within the ACO's integrated care management program for high-risk patients had lower monthly medical spending (by $1361 per person per month) as well as lower emergency department visit and hospitalization rates compared with similar patients who had yet to start the program. Accounting for early ACO departure decreased the magnitude of the program effects as expected. CONCLUSIONS: Commercial ACO populations may be healthy on average but still include some high-risk patients. Identifying which patients might benefit from more intensive care management could be critical for reaping the potential savings. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Commercial accountable care organization (ACO) contracts attempt to mitigate spending growth, but past evaluations have been limited to continuously enrolled ACO members in health maintenance organization (HMO) plans, excluding many members. The objective of this study was to examine the magnitude of turnover and leakage within a commercial ACO. STUDY DESIGN: A historical cohort study using detailed information from multiple commercial ACO contracts within a large health care system between 2015 and 2019. METHODS: Individuals insured through 1 of the 3 largest commercial ACO contracts during the study period, 2015-2019, were included. We examined patterns of entry and exit and the characteristics that predicted remaining in the ACO compared with leaving the ACO. We also examined predictors of the amount of care delivered in the ACO compared with outside the ACO. RESULTS: Among the 453,573 commercially insured individuals in the ACO, approximately half left the ACO within the initial 24 months after entry. Approximately one-third of spending was for care occurring outside the ACO. Patients who remained in the ACO differed from those who left earlier, including being older, having a non-HMO plan, having lower predicted spending at entry, and having more medical spending for care performed within the ACO during the initial quarter of membership. CONCLUSIONS: Both turnover and leakage hamper the ability of ACOs to manage spending. Modifications that address potentially intrinsic vs avoidable sources of population turnover and increase patient incentives for care within vs outside of ACOs could help address medical spending growth within commercial ACO programs.

OBJECTIVES: Care management programs are employed by providers and payers to support high-risk patients and affect cost and utilization, with varied implementation. This study sought to evaluate the impact of an intensive care management program on utilization and cost among those with highest cost (top 5%) and highest utilization in a Medicaid accountable care organization (ACO) population. STUDY DESIGN: Randomized controlled quality improvement trial of intensive care management, provided by a nonprofit care management vendor, for Medicaid ACO patients at 2 academic centers. METHODS: Patients were identified using claims, chart review, and primary care validation, then randomly assigned 2:1 to intervention and control groups. Among 131 patients included in intent-to-treat analysis, 87 and 44 were randomly assigned to the intervention and control groups, respectively. Patients in the intervention group were eligible to receive intensive care management in the community/home setting and, in some cases, home-based primary care. Patients in the control group received standard of care, including practice-based care management. Prespecified primary outcome measures included total medical expense (TME), emergency department (ED) visits, and inpatient utilization. RESULTS: Relative to controls, patients randomly assigned to receive intensive care management had a $1933 smaller increase per member per month in TME (P = .04) and directionally consistent but nonsignificant reductions in ED visits (17% fewer; P = .40) and inpatient admissions (34% fewer; P = .29) in the 12 months post randomization compared with the 12 months prerandomization. CONCLUSIONS: Our study results support that targeted, intensive care management can favorably affect TME in a health system--based high-cost, high-risk Medicaid population. Further research is needed to evaluate the impact on additional clinical outcomes. [ABSTRACT FROM AUTHOR]
