Objective: To examine how a novel payer-provider joint venture (JV) between one payer and multiple competitive delivery systems in New Hampshire (NH), which included value-based payment, care management, and non-financial supports, impacted healthcare value and payer and provider group experiences., Study Setting and Design: We conducted a mixed-methods study. We used a quasi-experimental longitudinal difference-in-differences design to examine the impact of the JV (which started in January 2016 and ended in December 2020) on healthcare utilization, quality, and spending, using members in Maine (ME) as a control group. We also analyzed patient uptake of the JV's care management program using routinely collected administrative data and assessed payer and provider group leaders' perspectives about the JV via semi-structured interviews., Data Sources and Analytic Sample: We used administrative and claims data from 2013 to 2019 in a commercially insured population under 65 years in NH and ME. We also used administrative data on care management eligibility and uptake and conducted semi-structured interviews with payer and provider group leaders affiliated with the JV., Principal Findings: The JV was associated with no sustained change in medical utilization, quality, and spending throughout the study period. In the first year of the JV, there was a $142 (95% confidence interval: $41, $243) increase in pharmaceutical spending per member and a 13% (4.4%, 25%) relative increase in days covered for diabetes medications. Only 15% of eligible members engaged in care management, which was a key component of the JV's multi-pronged approach. In a disconnect from the empirical findings, payer and provider group leaders believed that the JV reduced healthcare costs and improved quality., Conclusions: Our findings provide evidence for future payer-provider JVs and demonstrate the importance of having a valid control group when evaluating JVs and value-based payment arrangements., (© 2024 Health Research and Educational Trust.)

Objective: To examine the association between preventive drug lists (PDLs) and changes in medication costs among patients with diabetes insured in commercial health plans over 2 follow-up years., Research Design and Methods: We conducted a quasiexperimental study using the Optum deidentified Clinformatics Data Mart Database (January 2003 to December 2017). The intervention group included 5,582 patients with diabetes age 12-64 years switched by employers to PDL coverage; the control group included 5,582 matched patients whose employers offered no PDL. Outcomes included out-of-pocket costs, standardized costs, and 30-day fills for all medications because PDL-associated savings could be used to pay for medicines in other classes and for five therapeutic classes covered by the PDLs (oral diabetic medications, insulins, test strips, antihypertensive drugs, and lipid-lowering drugs)., Results: Pre- to post-out-of-pocket spending for all medications declined by 29.7% in follow-up year 2 (95% CI -36.0, -23.4%) among PDL members relative to controls. Higher-income and lower-income PDL members experienced significant reductions in out-of-pocket spending for all medications in year 2 (30%) and for key therapeutic classes (range -23 to -67%). We found significant increases in use of key therapeutic classes in the overall population (range 8-15%) and in higher-income and lower-income PDL members (range 9-50%)., Conclusions: PDLs offer an effective strategy for employers and insurers to lower member cost sharing and encourage increased use of important medications to prevent or manage chronic illnesses. For patients with diabetes, especially those with lower incomes, PDL coverage resulted in substantial and persistent reductions in out-of-pocket medication costs, medication use increases, and some increased use of more expensive products., (© 2024 by the American Diabetes Association.)

Objective: To compare the risk of incident cardiovascular disease (CVD) events following sleeve gastrectomy (SG) and Roux en Y gastric bypass (RYGB)., Summary Background Data: Bariatric surgery is associated with reduced CVD risk but the differential effect of contemporary bariatric procedures is unclear., Methods: We used insurance claims to conduct a retrospective cohort study of CVD outcomes for patients who underwent RYGB versus SG between 2010 and 2021. Patients were followed for up to 5 years for a primary composite major adverse cardiovascular event (MACE) outcome as well as individual outcomes including myocardial infarction, stroke, heart failure, and arrhythmia. We compared cumulative risks of CVD events using multivariable Cox proportional hazards modeling, in overall cohorts and in sub-cohorts of older adults and those with type 2 diabetes (T2D) or pre-existing CVD and elevated morbidity., Results: Matched, weighted cohorts of 13,545 SG and RYGB patients were observed for an average of 2.5 years after surgery, with 26.2% not lost to follow-up by the end of 5 years. There was no difference in MACE risk between procedures (aHR 1.01 for RYGB vs. SG [95% CI 0.90, 1.12]) in the overall cohort or among the subgroup of older adults (aHR 0.97 for RYGB vs. SG [95% CI 0.85, 1.10]). Patients with T2D experienced lower risk of MACE following RYGB compared to SG (aHR 0.78 [95% CI 0.66, 0.92]), as did those with pre-existing CVD or elevated morbidity prior to surgery (aHR 0.81 [95% CI 0.70, 0.93])., Conclusions: These findings further support the preferential use of RYGB over SG for patients with T2D or who have pre-existing CVD. However, among other groups of patients, including older adults, we did not observe a relative benefit of RYGB during the time horizon in this study., Competing Interests: Conflicts of Interest and Source of Funding: The authors have no conflicts of interest to disclose.

Objectives: Regular users of the emergency department (ED) include both patients who could be better served in lower-acuity settings and those with high-severity conditions. ED use decreased during the COVID-19 pandemic, but patterns among regular ED users are unknown. To determine the impact of the COVID-19 pandemic on this population, we examined quarterly postpandemic ED utilization among prepandemic regular ED users. Key subgroups included prepandemic ED users with regular visits for (1) low-severity conditions and (2) high-severity conditions., Study Design: An event study design with COVID-19 and historic controls cohorts., Methods: We identified 4710 regular ED users at baseline and followed their ED utilization for 7 quarters. We used a generalized estimating equations model to compare the relative quarterly percent difference in ED visit rates between the COVID-19 and historic controls cohorts., Results: The first postpandemic quarter was associated with the largest decline in ED visits, at -36.0% (95% CI, -42.0% to -29.3%) per regular ED user overall, -52.2% (95% CI, -69.4% to -25.3%) among high-severity users, and -29.6% (95% CI, -39.8% to -17.8%) among low-severity users. However, use did not statistically differ from expected levels after 5 quarters among all regular ED users, 1 quarter among high-severity users, and 3 quarters among regular low-severity users., Conclusions: Initial reductions among regular high-severity ED users raise concern for harm from delayed or missed care but did not result in increased high-severity visits later. Nonsustained declines among regular low-severity ED users suggest barriers to and opportunities for redirecting nonurgent ED use to lower-acuity settings.

Importance: Research has demonstrated an association between the COVID-19 pandemic and increased alcohol-related liver disease hospitalizations and deaths. However, trends in alcohol-related complications more broadly are unclear, especially among subgroups disproportionately affected by alcohol use., Objective: To assess trends in people with high-acuity alcohol-related complications admitted to the emergency department, observation unit, or hospital during the COVID-19 pandemic, focusing on demographic differences., Design, Setting, and Participants: This longitudinal interrupted time series cohort study analyzed US national insurance claims data using Optum's deidentified Clinformatics Data Mart database from March 2017 to September 2021, before and after the March 2020 COVID-19 pandemic onset. A rolling cohort of people 15 years and older who had at least 6 months of continuous commercial or Medicare Advantage coverage were included. Subgroups of interest included males and females stratified by age group. Data were analyzed from April 2023 to January 2024., Exposure: COVID-19 pandemic environment from March 2020 to September 2021., Main Outcomes and Measures: Differences between monthly rates vs predicted rates of high-acuity alcohol-related complication episodes, determined using claims-based algorithms and alcohol-specific diagnosis codes. The secondary outcome was the subset of complication episodes due to alcohol-related liver disease., Results: Rates of high-acuity alcohol-related complications were statistically higher than expected in 4 of 18 pandemic months after March 2020 (range of absolute and relative increases: 0.4-0.8 episodes per 100 000 people and 8.3%-19.4%, respectively). Women aged 40 to 64 years experienced statistically significant increases in 10 of 18 pandemic months (range of absolute and relative increases: 1.3-2.1 episodes per 100 000 people and 33.3%-56.0%, respectively). In this same population, rates of complication episodes due to alcohol-related liver disease increased above expected in 16 of 18 pandemic months (range of absolute and relative increases: 0.8-2.1 episodes per 100 000 people and 34.1%-94.7%, respectively)., Conclusions and Relevance: In this cohort study of a national, commercially insured population, high-acuity alcohol-related complication episodes increased beyond what was expected in 4 of 18 COVID-19 pandemic months. Women aged 40 to 64 years experienced 33.3% to 56.0% increases in complication episodes in 10 of 18 pandemic months, a pattern associated with large and sustained increases in high-acuity alcohol-related liver disease complications. Findings underscore the need for increased attention to alcohol use disorder risk factors, alcohol use patterns, alcohol-related health effects, and alcohol regulations and policies, especially among women aged 40 to 64 years.

Background: Twenty-five states have implemented insulin out-of-pocket (OOP) cost caps, but their effectiveness is uncertain., Objective: To examine the effect of state insulin OOP caps on insulin use and OOP costs among commercially insured persons with diabetes., Design: Pre-post study with control group., Setting: Eight states implementing insulin OOP caps of $25 to $30, $50, or $100 in January 2021, and 17 control states., Participants: Commercially insured persons with diabetes and insulin users younger than 65 years. Subgroups of particular interest included members from states with insulin OOP caps of $25 to $30, enrollees with health savings accounts (HSAs) that require high insulin OOP payments, and lower-income members., Measurements: Mean monthly 30-day insulin fills and OOP costs., Results: State insulin caps were not associated with changes in insulin use in the overall population (relative change in fills per month, 1.8% [95% CI, -3.2% to 6.9%]). Insulin users in intervention states saw a 17.4% (CI, -23.9% to -10.9%) relative reduction in insulin OOP costs, largely driven by reductions among HSA enrollees; there was no difference in OOP costs among nonaccount plan members. More generous ($25 to $30) state insulin OOP caps were associated with insulin OOP cost reductions of 40.0% (CI, -62.5% to -17.6%), again primarily driven by a larger reduction in the subgroup with HSA plans., Limitations: Single national insurer; 9-month follow-up., Conclusion: Insulin OOP caps were associated with reduced insulin OOP costs but no overall increases in insulin use. A proposed national insulin cap of $35 for commercially insured persons might lead to meaningful insulin OOP savings but have a limited effect on insulin use., Primary Funding Source: Centers for Disease Control and Prevention and National Institute of Diabetes and Digestive and Kidney Diseases., Competing Interests: Disclosures: Disclosures can be viewed at www.acponline.org/authors/icmje/ConflictOfInterestForms.do?msNum=M23-1965.

Objective: The objective of this study was to compare the impact of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) on overall and diabetes-specific health care costs among patients with type 2 diabetes., Methods: This retrospective cohort study examined patients with type 2 diabetes after SG and RYGB using data from Optum's deidentified Clinformatics® Data Mart database. The matched study group included 9608 patients who underwent SG or RYGB and were enrolled between 2007 and 2019. The primary outcomes assessed were overall and diabetes-specific health care costs., Results: Health care costs associated with type 2 diabetes declined substantially in the first few years following both SG and RYGB. RYGB was associated with a larger decrease in pharmacy costs, as well as type 2 diabetes-specific office and laboratory costs. SG was associated with lower total health care costs in the first three follow-up periods and lower acute care costs in the first 2 years after surgery., Conclusions: In this nationwide study, patients with type 2 diabetes at baseline undergoing RYGB appear to experience a reduced need for ambulatory type 2 diabetes monitoring and reduced requirements for antidiabetes medication but, despite this, did not experience an overall medical cost-benefit in the first few years after RYGB versus SG., (© 2024 The Authors.

Importance: High-deductible health plans (HDHPs) have grown rapidly and may adversely affect access to comprehensive cancer care., Objective: To evaluate the association of HDHPs with out-of-pocket medical costs and outpatient physician visits among patients with cancer., Design, Setting, and Participants: Using 2003 to 2017 data from the deidentified Optum Clinformatics Data Mart database from individuals with employer-sponsored health coverage, adults aged 18 to 64 years with cancer who were enrolled in low-deductible (≤$500 annually) health plans during a baseline year were identified. Patients whose employers then mandated a switch to an HDHP (≥$1000 annual deductible) were assigned to the HDHP group, while contemporaneous individuals with cancer at baseline who had no option but to continue enrollment in low-deductible plans were assigned to the control group. The 2 groups were matched on demographic variables (age, sex, race and ethnicity, US Census region, rural vs urban, and neighborhood poverty level), cancer type, morbidity score, number of baseline physician visits by specialty type, baseline out-of-pocket costs, and employer characteristics. These cohorts were followed up for up to 3 years after the baseline year. Data were analyzed from July 2021 to December 2022., Exposures: Employer-mandated HDHP enrollment., Main Outcomes and Measures: Out-of-pocket medical expenditures and outpatient visits to primary care physicians, cancer specialists, and noncancer specialists., Results: After matching, the sample included 45 708 patients with cancer (2703 patients in the HDHP group and 43 005 matched individuals in the control group); mean (SD) age in the HDHP and control groups was 52.9 (9.3) years and 52.9 (2.3) years, respectively, with 58.5% females in both groups. The matching procedure yielded variable weights for each individual in the control group, resulting in a weighted control group sample of 2703 patients. Patients with cancer who were switched to HDHPs experienced an increase in annual out-of-pocket medical expenditures of 68.1% (95% CI, 51.0%-85.3%; absolute increase, $1349.80 [95% CI, $1060.30-$1639.20]) after the switch compared with those who remained in traditional health plans. At follow-up, the number of oncology visits did not differ between the 2 groups (relative difference, 0.1%; 95% CI, -8.4% to 9.4%); however, the HDHP group had 10.8% (95% CI, -15.5% to -5.9%) fewer visits to primary care physicians and 5.9% (95% CI, -11.2% to -0.3%) fewer visits to noncancer specialists., Conclusions and Relevance: Results of this cohort study suggest that after enrollment in HDHPs, patients with cancer experienced substantial increases in out-of-pocket medical costs. The number of visits to oncologists was unchanged during follow-up, but the number of visits to noncancer physicians was lower. These findings suggest that HDHPs are unlikely to unfavorably affect key oncology services but might lead to less comprehensive care of cancer survivors.

Importance: The association of value-based medication benefits with diabetes health outcomes is uncertain., Objective: To assess the association of a preventive drug list (PDL) value-based medication benefit with acute, preventable diabetes complications., Design, Setting, and Participants: This cohort study used a controlled interrupted time series design and analyzed data from a large, national, commercial health plan from January 1, 2004, through June 30, 2017, for patients with diabetes aged 12 to 64 years enrolled through employers that adopted PDLs (intervention group) and matched and weighted members with diabetes whose employers did not adopt PDLs (control group). All participants were continuously enrolled and analyzed for 1 year before and after the index date. Subgroup analysis assessed patients with diabetes living in lower-income and higher-income neighborhoods. Data analysis was performed between August 19, 2020, and December 1, 2023., Exposure: At the index date, intervention group members experienced employer-mandated enrollment in a PDL benefit that was added to their follow-up year health plan. This benefit reduced out-of-pocket costs for common cardiometabolic drugs, including noninsulin antidiabetic agents and insulin. Matched control group members continued to have cardiometabolic medications subject to deductibles or co-payments at follow-up., Main Outcomes and Measures: The primary outcome was acute, preventable diabetes complications (eg, bacterial infections, neurovascular events, acute coronary disease, and diabetic ketoacidosis) measured as complication days per 1000 members per year. Intermediate measures included the proportion of days covered by and higher use (mean of 1 or more 30-day fills per month) of antidiabetic agents., Results: The study 10 588 patients in the intervention group (55.2% male; mean [SD] age, 51.1 [10.1] years) and 690 075 patients in the control group (55.2% male; mean [SD] age, 51.1 [10.1] years) after matching and weighting. From baseline to follow-up, the proportion of days covered by noninsulin antidiabetic agents increased by 4.7% (95% CI, 3.2%-6.2%) in the PDL group and by 7.3% (95% CI, 5.1%-9.5%) among PDL members from lower-income areas compared with controls. Higher use of noninsulin antidiabetic agents increased by 11.3% (95% CI, 8.2%-14.5%) in the PDL group and by 15.2% (95% CI, 10.6%-19.8%) among members of the PDL group from lower-income areas compared with controls. The PDL group experienced an 8.4% relative reduction in complication days (95% CI, -13.9% to -2.8%; absolute reduction, -20.2 [95% CI, -34.3 to -6.2] per 1000 members per year) compared with controls from baseline to follow-up, while PDL members residing in lower-income areas had a 10.2% relative reduction (95% CI, -17.4% to -3.0%; absolute, -26.1 [95% CI, -45.8 to -6.5] per 1000 members per year)., Conclusions and Relevance: In this cohort study, acute, preventable diabetes complication days decreased by 8.4% in the overall PDL group and by 10.2% among PDL members from lower-income areas compared with the control group. The results may support a strategy of incentivizing adoption of targeted cost-sharing reductions among commercially insured patients with diabetes and lower income to enhance health outcomes.

Postoperative orthopedic patients are a high-risk group for receiving long-duration, large-dosage opioid prescriptions. Rigorous evaluation of state opioid duration limit laws, enacted throughout the country in response to the opioid overdose epidemic, is lacking among this high-risk group. We took advantage of Massachusetts' early implementation of a 2016 7-day-limit law that occurred before other statewide or plan-wide policies took effect and used commercial insurance claims from 2014-2017 to study its association with postoperative opioid prescriptions greater than 7 days' duration among Massachusetts orthopedic patients relative to a New Hampshire control group. Our sample included 14 097 commercially insured, opioid-naive adults aged 18 years and older undergoing elective orthopedic procedures. We found that the Massachusetts 7-day limit was associated with an immediate 4.23 percentage point absolute reduction (95% CI, 8.12 to 0.33 percentage points) and a 33.27% relative reduction (95% CI, 55.36% to 11.19%) in the percentage of initial fills greater than 7 days in the Massachusetts relative to the control group. Seven-day-limit laws may be an important state-level tool to mitigate longer duration prescribing to high-risk postoperative populations., Competing Interests: Conflicts of interest Please see ICMJE form(s) for author conflicts of interest.

Importance: High-deductible health plans with health savings accounts (HDHP-HSAs) incentivize patients to use less health care, including necessary care. Preventive drug lists (PDLs) exempt high-value medications from the deductible, reducing out-of-pocket cost sharing; the associations of PDLs with health outcomes among patients with asthma is unknown., Objective: To evaluate the associations of a PDL for asthma medications on utilization, adverse outcomes, and patient spending for HDHP-HSA enrollees with asthma., Design, Setting, and Participants: This case-control study used matched groups of patients with asthma before and after an insurance design change using a national commercial health insurance claims data set from 2004-2017. Participants included patients aged 4 to 64 years enrolled for 1 year in an HDHP-HSA without a PDL in which asthma medications were subject to the deductible who then transitioned to an HDHP-HSA with a PDL that included asthma medications; these patients were compared with a matched weighted sample of patients with 2 years of continuous enrollment in an HDHP-HSA without a PDL. Models controlled for patient demographics and asthma severity and were stratified by neighborhood income. Analyses were conducted from October 2020 to June 2023., Exposures: Employer-mandated addition of a PDL that included asthma medications to an existing HDHP-HSA., Main Outcomes and Measures: Outcomes of interest were utilization of asthma medications on the PDL (controllers and albuterol), asthma exacerbations (oral steroid bursts and asthma-related emergency department use), and out-of-pocket spending (all and asthma-specific)., Results: A total of 12 174 participants (mean [SD] age, 36.9 [16.9] years; 6848 [56.25%] female) were included in analyses. Compared with no PDL, PDLs were associated with increased rates of 30-day fills per enrollee for any controller medication (change, 0.10 [95% CI, 0.03 to 0.17] fills per enrollee; 12.9% increase) and for combination inhaled corticosteroid long-acting β2-agonist (ICS-LABA) medications (change, 0.06 [95% CI, 0.01 to 0.10] fills per enrollee; 25.4% increase), and increased proportion of days covered with ICS-LABA (6.0% [0.7% to 11.3%] of days; 15.6% increase). Gaining a PDL was associated with decreased out-of-pocket spending on asthma care (change, -$34 [95% CI, -$47 to -$21] per enrollee; 28.4% difference), but there was no significant change in asthma exacerbations and no difference in results by income., Conclusions and Relevance: In this case-control study, reducing cost-sharing for asthma medications through a PDL was associated with increased adherence to controller medications, notably ICS-LABA medications used by patients with more severe asthma, but was not associated with improved clinical outcomes. These findings suggest that PDLs are a potential strategy to improve access and affordability of asthma care for patients in HDHP-HSAs.

Objective: To compare acute care utilization and costs following sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB)., Summary Background Data: Comparing postbariatric emergency department (ED) and inpatient care use patterns could assist with procedure choice and provide insights about complication risk., Methods: We used a national insurance claims database to identify adults undergoing SG and RYGB between 2008 and 2016. Patients were matched on age, sex, calendar-time, diabetes, and baseline acute care use. We used adjusted Cox proportional hazards to compare acute care utilization and 2-part logistic regression models to compare annual associated costs (odds of any cost, and odds of high costs, defined as ≥80th percentile), between SG and RYGB, overall and within several clinical categories., Results: The matched cohort included 4263 SG and 4520 RYGB patients. Up to 4 years after surgery, SG patients had slightly lower risk of ED visits [adjusted hazard ratio (aHR): 0.90; 95% confidence interval (CI): 0.85,0.96] and inpatient stays (aHR: 0.80; 95% CI: 0.73,0.88), especially for events associated with digestive-system diagnoses (ED aHR: 0.68; 95% CI: 0.62,0.75; inpatient aHR: 0.61; 95% CI: 0.53,0.72). SG patients also had lower odds of high ED and high total acute costs (eg, year-1 acute costs adjusted odds ratio (aOR) 0.77; 95% CI: 0.66,0.90) in early follow-up. However, observed cost differences decreased by years 3 and 4 (eg, year-4 acute care costs aOR 1.10; 95% CI: 0.92,1.31)., Conclusions: SG may have fewer complications requiring emergency care and hospitalization, especially as related to digestive system disease. However, any acute care cost advantages of SG may wane over time., (Copyright © 2021 The Author(s). Published by Wolters Kluwer Health, Inc.)

Objective: Lack of effective transition from pediatric to adult care may contribute to adverse outcomes in young adults with type 1 diabetes. The understanding of outpatient and acute care utilization patterns across the adolescent to young adult transition age in type 1 diabetes populations is suboptimal in the U.S., Research Design and Methods: We studied claims data from 14,616 individuals diagnosed with type 1 diabetes, aged 16-24 years, and enrolled in a large national health plan for ≥1 year from 2005 to 2012. Annual outpatient and emergency department visits and hospitalization rates were calculated at each age. Generalized estimating equations were used to assess the association of age-group (adolescents [age 16-18 years] vs. young adults [age 19-24 years]), outpatient visits, and sociodemographic variables with emergency department visit and hospitalization rates., Results: Endocrinologist visits declined from 2.3 per year at age 16 years to 1.5 per year by age 22. Emergency department rates increased per year from 45 per 100 at age 16 to 63 per 100 at age 20, then decreased to 60 per 100 by age 24. Hospitalizations per year climbed from 14 per 100 at age 16 to 21 per 100 at age 19, then decreased to 17 per 100 by age 24. In statistical models, young adults experienced higher rates of emergency department visits (incidence rate ratio [IRR] 1.24 [95% CI 1.18, 1.31]) and hospitalizations (IRR 1.25 [95% CI 1.15, 1.36]) than adolescents. Additional significant predictors of emergency department visits and hospitalizations included female sex and Black race. Individuals with two or more endocrinologist visits per year were less likely to have emergency department visits and hospitalizations; higher income was also protective., Conclusions: Results highlight concerning increases in acute care utilization for young adults with type 1 diabetes who are less engaged with outpatient diabetes care and highlight socioeconomic risk factors that warrant further study., (© 2022 by the American Diabetes Association.)

Importance: Whether interprofessional collaboration is effective and safe in decreasing hospital length of stay remains controversial., Objective: To evaluate the outcomes and safety associated with an electronic interprofessional-led discharge planning tool vs standard discharge planning to safely reduce length of stay among medical inpatients with multimorbidity., Design, Setting, and Participants: This multicenter prospective nonrandomized controlled trial used interrupted time series analysis to examine medical acute hospitalizations at 82 hospitals in Switzerland. It was conducted from February 2017 through January 2019. Data analysis was conducted from March 2021 to July 2022., Intervention: After a 12-month preintervention phase (February 2017 through January 2018), an electronic interprofessional-led discharge planning tool was implemented in February 2018 in 7 intervention hospitals in addition to standard discharge planning., Main Outcomes and Measures: Mixed-effects segmented regression analyses were used to compare monthly changes in trends of length of stay, hospital readmission, in-hospital mortality, and facility discharge after the implementation of the tool with changes in trends among control hospitals., Results: There were 54 695 hospitalizations at intervention hospitals, with 27 219 in the preintervention period (median [IQR] age, 72 [59-82] years; 14 400 [52.9%] men) and 27 476 in the intervention phase (median [IQR] age, 72 [59-82] years; 14 448 [52.6%] men) and 438 791 at control hospitals, with 216 261 in the preintervention period (median [IQR] age, 74 [60-83] years; 109 770 [50.8%] men) and 222 530 in the intervention phase (median [IQR] age, 74 [60-83] years; 113 053 [50.8%] men). The mean (SD) length of stay in the preintervention phase was 7.6 (7.1) days for intervention hospitals and 7.5 (7.4) days for control hospitals. During the preintervention phase, population-averaged length of stay decreased by -0.344 hr/mo (95% CI, -0.599 to -0.090 hr/mo) in control hospitals; however, no change in trend was observed among intervention hospitals (-0.034 hr/mo; 95% CI, -0.646 to 0.714 hr/mo; difference in slopes, P = .09). Over the intervention phase (February 2018 through January 2019), length of stay remained unchanged in control hospitals (slope, -0.011 hr/mo; 95% CI, -0.281 to 0.260 hr/mo; change in slope, P = .03), but decreased steadily among intervention hospitals by -0.879 hr/mo (95% CI, -1.607 to -0.150 hr/mo; change in slope, P = .04, difference in slopes, P = .03). Safety analyses showed no change in trends of hospital readmission, in-hospital mortality, or facility discharge over the whole study time., Conclusions and Relevance: In this nonrandomized controlled trial, the implementation of an electronic interprofessional-led discharge planning tool was associated with a decline in length of stay without an increase in hospital readmission, in-hospital mortality, or facility discharge., Trial Registration: isrctn.org Identifier: ISRCTN83274049.

Objective: The Affordable Care Act mandates that primary preventive services have no out-of-pocket costs but does not exempt secondary prevention from out-of-pocket costs. Most commercially insured patients with diabetes have high-deductible health plans (HDHPs) that subject key microvascular disease-related services to high out-of-pocket costs. Brief treatment delays can significantly worsen microvascular disease outcomes., Research Design and Methods: This cohort study used a large national commercial (and Medicare Advantage) health insurance claims data set to examine matched groups before and after an insurance design change. The study group included 50,790 patients with diabetes who were continuously enrolled in low-deductible (≤$500) health plans during a baseline year, followed by up to 4 years in high-deductible (≥$1,000) plans after an employer-mandated switch. HDHPs had low out-of-pocket costs for nephropathy screening but not retinopathy screening. A matched control group included 335,178 patients with diabetes who were contemporaneously enrolled in low-deductible plans. Measures included time to first detected microvascular disease screening, severe microvascular disease diagnosis, vision loss diagnosis/treatment, and renal function loss diagnosis/treatment., Results: HDHP enrollment was associated with relative delays in retinopathy screening (0.7 months [95% CI 0.4, 1.0]), severe retinopathy diagnosis (2.9 months [0.5, 5.3]), and vision loss diagnosis/treatment (3.8 months [1.2, 6.3]). Nephropathy-associated measures did not change to a statistically significant degree among HDHP members relative to control subjects at follow-up., Conclusions: People with diabetes in HDHPs experienced delayed retinopathy diagnosis and vision loss diagnosis/treatment of up to 3.8 months compared with low-deductible plan enrollees. Findings raise concerns about visual health among HDHP members and call attention to discrepancies in Affordable Care Act cost sharing exemptions., (© 2022 by the American Diabetes Association.)

Paid sick leave provides workers with job-protected paid time off to address short-term illnesses or seek preventive care for themselves and their family members. We studied the impact of mandatory paid sick leave at the state level on emergency department (ED) visit rates, using all-payer, longitudinal ED data from the Healthcare Cost and Utilization Project for the period 2011-19. We found that state implementation of paid sick leave mandates was associated with a 5.6 percent reduction in the total ED visit rate relative to the baseline, equivalent to 23 fewer visits per 1,000 population per year. The reduction was concentrated in Medicaid patients. Some of the largest reductions were ED visits related to adult dental conditions, adult mental health or substance use disorders, and pediatric asthma. Mandatory paid sick leave may be an effective policy lever to reduce excess ED use and costs.

Purpose of Review: Diabetes is an ongoing public health issue in the USA, and, despite progress, recent reports suggest acute and chronic diabetes complications are increasing., Recent Findings: The Natural Experiments for Translation in Diabetes 3.0 (NEXT-D3) Network is a 5-year research collaboration involving six academic centers (Harvard University, Northwestern University, Oregon Health & Science University, Tulane University, University of California Los Angeles, and University of California San Francisco) and two funding agencies (Centers for Disease Control and Prevention and National Institutes of Health) to address the gaps leading to persisting diabetes burdens. The network builds on previously funded networks, expanding to include type 2 diabetes (T2D) prevention and an emphasis on health equity. NEXT-D3 researchers use rigorous natural experiment study designs to evaluate impacts of naturally occurring programs and policies, with a focus on diabetes-related outcomes. NEXT-D3 projects address whether and to what extent federal or state legislative policies and health plan innovations affect T2D risk and diabetes treatment and outcomes in the USA; real-world effects of increased access to health insurance under the Affordable Care Act; and the effectiveness of interventions that reduce barriers to medication access (e.g., decreased or eliminated cost sharing for cardiometabolic medications and new medications such as SGLT-2 inhibitors for Medicaid patients). Overarching goals include (1) expanding generalizable knowledge about policies and programs to manage or prevent T2D and educate decision-makers and organizations and (2) generating evidence to guide the development of health equity goals to reduce disparities in T2D-related risk factors, treatment, and complications., (© 2022.

Importance: Studies comparing contemporary bariatric surgical types could facilitate procedure selection for patients interested in reducing their frequency of health care visits and reliance on prescription drugs., Objective: To compare the association of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) with ambulatory health care costs and use for as long as 4 years after surgery., Design, Setting, and Participants: This comparative effectiveness study, which included patients undergoing bariatric surgery who were aged 18 to 64 years with at least 24 months of enrollment data before surgery and 12 months of enrollment data after surgery, used a retrospective interrupted time series with a comparison group. Data represent insurance claims dated January 2006 to June 2017, with analyses completed in September 2021. Data were collected from US commercial and Medicare Advantage claims database. Cohorts were matched on characteristics including baseline body mass index category, diabetes status, baseline ambulatory care costs, region of the United States, and year of surgery., Exposures: SG or RYGB, based on procedure codes., Main Outcomes and Measures: Annual ambulatory health care costs, and subtypes of cost and use including prescriptions, office visits, laboratory encounters, and radiology., Results: Matched cohorts included 3049 patients who underwent SG and 3251 patients who underwent RYGB, with a mean (SD) age of 45.2 (10.0) years; 4820 (77%) were women. Full follow-up was 37% for SG (514 patients) and 38% for RYGB (643 patients) among those eligible for 4-year follow-up. There were no significant differences between SG and RYGB in total ambulatory costs, office visit costs, or radiology costs in all follow-up years. Patients who underwent SG had significantly higher prescription costs than those who underwent RYGB bypass in year 4 ($852.8 per patient per year; 95% CI: $395.6-$1310.0 per patient per year) with more cardiometabolic medication fills in each year (eg, year 4: 42.5%; 95% CI, 13.7%-71.2%). In contrast, early after surgery, patients who underwent SG had relatively fewer specialist visits (eg, year 1: -7.2%; 95% CI, -14.3% to -0.2%) and lower laboratory costs (eg, year 1: -$118.9 per patient per year; 95% CI, -$220.2 to -$17.5 per patient per year)., Conclusions and Relevance: Despite clinical studies showing greater weight loss and comorbidity improvement with RYGB vs SG, this study found no difference in total ambulatory costs for as long as 4 years after SG and RYGB. These findings may reflect the trade-off between greater improvements in cardiometabolic health and additional surgery-related care among patients undergoing RYGB. Studies with longer follow-up time could determine whether greater sustained weight loss from RYGB eventually results in lower costs compared with SG.

Purpose: Early palliative care, concomitant with disease-directed treatments, is recommended for all patients with advanced cancer. This study assesses population-level trends in palliative care use among a large cohort of commercially insured patients with metastatic cancer, applying an expanded definition of palliative care services based on claims data., Methods: Using nationally representative commercial insurance claims data, we identified patients with metastatic breast, colorectal, lung, bronchus, trachea, ovarian, esophageal, pancreatic, and liver cancers and melanoma between 2001 and 2016. We assessed the annual proportions of these patients who received services specified as, or indicative of, palliative care. Using Cox proportional hazard models, we assessed whether the time from diagnosis of metastatic cancer to first encounter of palliative care differed by demographic characteristics, socioeconomic factors, or region., Results: In 2016, 36% of patients with very poor prognosis cancers received a service specified as, or indicative of, palliative care versus 18% of those with poor prognosis cancers. Being diagnosed in more recent years (2009-2016 v 2001-2008: hazard ratio [HR], 1.8; P < .001); a diagnosis of metastatic esophagus, liver, lung, or pancreatic cancer, or melanoma ( v breast cancer, eg, esophagus HR, 1.89; P < .001); a greater number of comorbidities (American Hospital Formulary Service classes > 10 v 0: HR, 1.71; P < .001); and living in the Northeast (HR, 1.43; P < .001) or Midwest ( v South: HR, 1.39; P < .001) were the strongest predictors of shorter time from diagnosis to palliative care., Conclusion: Use of palliative care among commercially insured patients with advanced cancers has increased since 2001. However, even with an expanded definition of services specified as, or indicative of, palliative care, < 40% of patients with advanced cancers received palliative care in 2016., Competing Interests: Fang ZhangResearch Funding: GlaxoSmithKlineNo other potential conflicts of interest were reported.

Background: Annual mammography is recommended for breast cancer survivors; however, population-level temporal trends in surveillance mammography participation have not been described. Our objective was to characterize trends in annual surveillance mammography participation among women with a personal history of breast cancer over a 13-year period., Methods: We examined annual surveillance mammography participation from 2004 to 2016 in a nationwide sample of commercially insured women with prior breast cancer. Rates were stratified by age group (40-49 vs 50-64 years), visit with a surgical/oncology specialist or primary care provider within the prior year, and sociodemographic characteristics. Joinpoint models were used to estimate annual percentage changes (APCs) in participation during the study period., Results: Among 141,672 women, mammography rates declined from 74.1% in 2004 to 67.1% in 2016. Rates were stable from 2004 to 2009 (APC, 0.1%; 95% CI, -0.5% to 0.8%) but declined 1.5% annually from 2009 to 2016 (95% CI, -1.9% to -1.1%). For women aged 40 to 49 years, rates declined 2.8% annually (95% CI, -3.4% to -2.1%) after 2009 versus 1.4% annually in women aged 50 to 64 years (95% CI, -1.9% to -1.0%). Similar trends were observed in women who had seen a surgeon/oncologist (APC, -1.7%; 95% CI, -2.1% to -1.4%) or a primary care provider (APC, -1.6%; 95% CI, -2.1% to -1.2%) in the prior year., Conclusions: Surveillance mammography participation among breast cancer survivors declined from 2009 to 2016, most notably among women aged 40 to 49 years. These findings highlight a need for focused efforts to improve adherence to surveillance and prevent delays in detection of breast cancer recurrence and second cancers.

Objective: High-deductible health plans paired with health savings accounts (HSA-HDHPs) require substantial out-of-pocket spending for most services, including medications. We examined effects of HSA-HDHPs on medication out-of-pocket spending and use among people with bipolar disorder., Methods: This quasi-experimental study used claims data for January 2003 through December 2014. We studied a national sample of 348 members with bipolar disorder (defined based on International Classification of Diseases, 9th Revision ), aged 12 to 64 years, who were continuously enrolled for 1 year in a low-deductible plan (≤ $500) then 1 year in an HSA-HDHP (≥ $1,000) after an employer-mandated switch. HSA-HDHP members were matched to 4,087 contemporaneous controls who remained in low-deductible plans. Outcome measures included out-of-pocket spending and use of bipolar disorder medications, non-bipolar psychotropics, and all other medications., Results: Mean pre-to-post out-of-pocket spending per person for bipolar disorder medications increased by 149.7% among HSA-HDHP versus control members (95% confidence interval [CI], 109.9% to 189.5%). Specifically, out-of-pocket spending increased for antipsychotics (220.9% [95% CI, 150.0% to 291.8%]) and anticonvulsants (109.6% [95% CI, 67.3% to 152.0%]). Both higher-income and lower-income HSA-HDHP members experienced increases in out-of-pocket spending for bipolar disorder medications (135.2% [95% CI, 86.4% to 184.0%] and 164.5% [95% CI, 100.9% to 228.1%], respectively). We did not detect statistically significant changes in use of bipolar disorder medications, non-bipolar psychotropics, or all other medications in this study population of HSA-HDHP members., Conclusions: HSA-HDHP members with bipolar disorder experienced substantial increases in out-of-pocket burdens for medications essential for their functioning and well-being. Although HSA-HDHPs were not associated with detectable reductions in medication use, high out-of-pocket costs could cause financial strain for lower-income enrollees., (© Copyright 2022 Physicians Postgraduate Press, Inc.)

Background: Out-of-pocket (OOP) health care costs can cause financial burden and deferred care for many Americans. Little is known about OOP spending for asthma-related care among the commercially insured., Objectives: To analyze OOP spending for asthma-related care overall, across types of care, and by income., Methods: Using enrollment, claims, and geocoded census tract data on income from a large US commercial health plan from 2004 to 2016, we measured inflation-adjusted OOP spending for individuals with asthma ages 4 to 64 years (n = 1,986,769). We estimated annual asthma-related OOP spending over time, and average total, asthma-related, asthma type of care, and asthma medication spending by income. We measured trends in median OOP cost per medication. Linear regression models were adjusted for patient covariates and deductible level., Results: Asthma-related OOP spending decreased over time both for patients enrolled in high-deductible health plans and for those in traditional plans. High-deductible plan enrollment increased from 7% to 54%. Compared with patients living in high-income areas, patients in the lowest-income areas had similar annual total and asthma-related OOP spending, but spent 30% less on controller medications and a higher proportion of their asthma-related OOP spending on inpatient and emergency care (10% vs 3%; P < .001). Asthma-related OOP spending represented a higher proportion of household income for patients in lower-income areas., Conclusions: Patients with asthma living in the lowest-income areas have greater cost burden, lower spending on controller medications, and greater spending on high-acuity care than higher-income counterparts., (Copyright © 2021 American Academy of Allergy, Asthma & Immunology.

Objectives: To examine trends in high deductible health plan (HDHP) enrolment among members with diabetes and cardiovascular disease (CVD) compared with healthy members and compare out-of-pocket (OOP) and total spending for members with chronic conditions in HDHPs versus low deductible plans., Design: Descriptive study with time trends., Setting: A large national commercial insurance database., Participants: 1.2 million members with diabetes, 4.5 million members with CVD (without diabetes) and 18 million healthy members (defined by a low comorbidity score) under the age of 65 years and insured between 2005 and 2013., Outcome Measures: Percentage of members in an HDHP (ie, annual deductible ≥$1000) by year, annual mean OOP and total spending, adjusted for member sociodemographic and employer characteristics., Results: Enrolment in HDHPs among members in all disease categories increased by 5 percentage points a year and was over 50% by 2013. On average, over the study period, HDHP enrolment among members with diabetes and CVD was 2.84 (95% CI: 2.78 to 2.90) and 2.02 (95% CI: 1.98 to 2.05) percentage points lower, respectively, than among healthy members. HDHP members with diabetes, CVD and low morbidity had higher annual OOP costs ($636 (95% CI: 630 to 642), $539 (95% CI: 537 to 542) and $113 (95% CI: 112 to 113)) and lower total costs (-$529 (95% CI: -597 to -461), -$364 (95% CI: -385 to -342) and -$79 (95% CI: -81 to -76)), respectively, than corresponding low deductible members when averaged over the study period. Members with chronic diseases had yearly OOP expenditures that were five to seven times higher than healthier members., Conclusion: High HDHP enrolment coupled with the high OOP costs associated with HDHPs may be particularly detrimental to the financial well-being of people with diabetes and CVD, who have more healthcare needs than healthier populations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: Timely evaluation of acute chest pain is necessary, although most evaluations will not find significant coronary disease. With employers increasingly adopting high-deductible health plans (HDHP), how HDHPs impact subsequent care after an emergency department (ED) diagnosis of nonspecific chest pain is unclear., Methods: Using a commercial and Medicare Advantage claims database, we identified members 19 to 63 years old whose employers exclusively offered low-deductible (≤$500) plans in 1 year, then, at an index date, mandated enrollment in HDHPs (≥$1000) for a subsequent year. We matched them with contemporaneous members whose employers only offered low-deductible plans. Primary outcomes included population rates of index ED visits with a principal diagnosis of nonspecific chest pain, admission during index ED visits, and index ED visits followed by noninvasive cardiac testing within 3 and 30 days, coronary revascularization, and acute myocardial infarction hospitalization within 30 days. We performed a cumulative interrupted time-series analysis, comparing changes in annual outcomes between the HDHP and control groups before and after the index date using aggregate-level segmented regression. Members from higher-poverty neighborhoods were a subgroup of interest., Results: After matching, we included 557 501 members in the HDHP group and 5 861 990 in the control group, with mean ages of 42.0 years, 48% to 49% female, and 67% to 68% non-Hispanic White individuals. Employer-mandated HDHP switches were associated with a relative decrease of 4.3% (95% CI, -5.9 to -2.7; absolute change, -4.5 [95% CI, -6.3 to -2.8] per 10 000 person-years) in nonspecific chest pain ED visits and 11.3% (95% CI, -14.0 to -8.6) decrease (absolute change, -1.7 per 10 000 person-years [95% CI, -2.1 to -1.2]) in visits leading to hospitalization. There was no significant decrease in subsequent noninvasive testing or revascularization procedures. An increase in 30-day acute myocardial infarction admissions was not statistically significant (15.9% [95% CI, -1.0 to 32.7]; absolute change, 0.3 per 10 000 person-years [95% CI, -0.01 to 0.5]) but was significant among members from higher-poverty neighborhoods., Conclusions: Employer-mandated HDHP switches were associated with decreased nonspecific chest pain ED visits and hospitalization from these ED visits, but no significant change in post-ED cardiac testing. However, HDHP enrollment was associated with increased 30-day acute myocardial infarction admission after ED diagnosis of nonspecific chest pain among members from higher-poverty neighborhoods.

Objective: To examine the effect of an employer-mandated switch to high-deductible health plans (HDHP) on emergency department (ED) low-value imaging., Data Sources: Claims data of a large national insurer between 2003 and 2014., Study Design: Difference-in-differences analysis with matched control groups., Data Collection/extraction Methods: The primary outcome is low-value imaging during ED visits for syncope, headache, or low back pain. We included members aged 19-63 years whose employers offered only low-deductible (≤$500) plans for one (baseline) year and, in the next (follow-up) year, offered only HDHPs (≥$1000). Contemporaneous members whose employers offered only low-deductible plans for two consecutive years served as controls. The groups were matched by person and employer propensity for HDHP switch, employer size, baseline calendar year, and baseline year quarterly number of total and imaged ED visits for each condition. We modeled the visit-level probability of low-value imaging using multivariable logistic regression with member-clustered standard errors. We also calculated population level monthly cumulative ED visit rates and modeled their trends using generalized linear regression adjusting for serial autocorrelation., Principal Findings: After matching, we included 524 998 members in the HDHP group and 5 448 803 in the control group with a mean age of approximately 42 years and 48% female in both groups. On visit-level analyses, there were no significant differential changes in the probability of low-value imaging use in the HDHP and control groups. In population-level analyses, compared with control group members, members who switched to HDHPs experienced a relative decrease of 5.9% (95% CI - 10.3, -1.6) in ED visits for the study conditions and a relative decrease of 5.1% (95%CI -9.6, -0.6) in the subset of ED visits with low-value imaging., Conclusion: Though HDHP switches decreased ED utilization, they had no significant effect on low-value imaging use after patients have decided to seek ED care., (© 2020 Health Research and Educational Trust.)

Importance: High-deductible health plans (HDHPs) are increasingly common and associated with decreased medication use in some adult populations. How children are affected is less certain., Objective: To examine the association between HDHP enrollment and asthma controller medication use and exacerbations., Design, Setting, and Participants: For this longitudinal cohort study with a difference-in-differences design, data were obtained from a large, national, commercial (and Medicare Advantage) administrative claims database between January 1, 2002, and December 31, 2014. Children aged 4 to 17 years and adults aged 18 to 64 years with persistent asthma who switched from traditional plans to HDHPs or remained in traditional plans (control group) by employer choice during a 24-month period were identified. A coarsened exact matching technique was used to balance the groups on characteristics including employer and enrollee propensity to have HDHPs. In most HDHPs, asthma medications were exempt from the deductible and subject to copayments. Statistical analyses were conducted from August 13, 2019, to January 19, 2021., Exposure: Employer-mandated HDHP transition., Main Outcomes and Measures: Thirty-day fill rates and adherence (based on proportion of days covered [PDC]) were measured for asthma controller medications (inhaled corticosteroid [ICS], leukotriene inhibitors, and ICS long-acting β-agonists [ICS-LABAs]). Asthma exacerbations were measured by rates of oral corticosteroid bursts and asthma-related emergency department visits among controller medication users., Results: The HDHP group included 7275 children (mean [SD] age, 10.8 [3.3] years; 4402 boys [60.5%]; and 5172 non-Hispanic White children [71.1%]) and 17 614 adults (mean [SD] age, 41.1 [13.4] years; 10 464 women [59.4%]; and 12 548 non-Hispanic White adults [71.2%]). The matched control group included 45 549 children and 114 141 adults. Compared with controls, children switching to HDHPs experienced significant absolute decreases in annual 30-day fills only for ICS-LABA medications (absolute change, -0.04; 95% CI, -0.07 to -0.01). Adults switching to HDHPs did not have significant reductions in 30-day fills for any controllers. There were no statistically significant differences in PDC, oral steroid bursts, or asthma-related emergency department visits for children or adults. For the 9.9% of HDHP enrollees with health savings account-eligible HDHPs that subjected medications to the deductible, there was a significant absolute decrease in PDC for ICS-LABA compared with controls (-4.8%; 95% CI, -7.7% to -1.9%)., Conclusions and Relevance: This cohort study found that in a population where medications were exempt from the deductible for most enrollees, HDHP enrollment was associated with minimal or no reductions in controller medication use for children and adults and no change in asthma exacerbations. These findings suggest a potential benefit from exempting asthma medications from the deductible in HDHPs.

Objective: High-deductible health plans (HDHPs) require substantial out-of-pocket spending for most services, although medications may be subject to traditional copayment arrangements. This study examined effects of HDHPs on medication out-of-pocket spending and use and quality of care among individuals with bipolar disorder., Methods: This quasi-experimental study used claims data (2003-2014) for a national sample of 3,532 members with bipolar disorder, ages 12-64, continuously enrolled for 1 year in a low-deductible plan (≤$500) and then for 1 year in an HDHP (≥$1,000) after an employer-mandated switch. HDHP members were matched to 18,923 contemporaneous individuals in low-deductible plans (control group). Outcome measures were out-of-pocket spending and use of bipolar disorder medications, psychotropics for other disorders, and all other medications and appropriate laboratory monitoring for psychotropics., Results: Relative to the control group, annual out-of-pocket spending per person for bipolar disorder medications increased 20.8% among HDHP members (95% confidence interval [CI]=14.9%-26.7%), and the absolute increase was $36 (95% CI=$25.9-$45.2). Specifically, out-of-pocket spending increased for antipsychotics (27.1%; 95% CI=17.4%-36.7%) and anticonvulsants (19.2%; 95% CI=11.9%-26.6%) but remained stable for lithium (-3.7%; 95% CI=-12.2% to 4.8%). No statistically significant changes were detected in use of bipolar disorder medications, other psychotropics, or all other medications or in appropriate laboratory monitoring for bipolar disorder medications., Conclusions: HDHP members with bipolar disorder experienced a moderate increase in out-of-pocket spending for medications but preserved bipolar disorder medication use. Findings may reflect individuals' perceptions of the importance of these medications for their functioning and well-being.

Objective: The aim of the study was to compare diabetes outcomes following vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB)., Background: There are few comparative studies on diabetes outcomes after VSG and RYGB., Methods: We used a US-wide commercial insurance claims database to identify adults with diabetes undergoing VSG or RYGB in 2010 to 2016. We matched patients on baseline insulin use, total diabetes medication burden, age, presence of diabetes complications, and follow-up duration, and used adjusted Cox proportional hazards models to compare diabetes medication discontinuation between procedures. We used difference-in-differences analyses to compare changes in medication use intensity up to 2 years after surgery., Results: The matched cohort included 1111 VSG and 922 RYGB patients: 16% were younger than 40 years, 11% were 60 years or older, 67% were women, 67% had a body mass index of 40 kg/m2 or higher, and 23% were on insulin at the time of surgery. Thirteen percent were lost to follow-up at 1 year, and 30% at 2 years after surgery. Patients with VSG were less likely than matched RYGB patients to discontinue all diabetes medications (hazard ratio 0.80, 95% confidence interval 0.72-0.88). Although both groups had substantial decreases in medication use after surgery, RYGB patients had an 86% (32%, 140%) lower total diabetes medication dose than VSG by the second half of postoperative year 2., Conclusions: In a large claims-based, nationwide cohort of bariatric patients with diabetes, those undergoing RYGB were more likely to come off all medications than those undergoing VSG. Patients with diabetes should consider this potential benefit of RYGB when making informed decisions about obesity treatments., Competing Interests: The authors report no conflicts of interest., (Copyright © 2019 Wolters Kluwer Health, Inc.

Background: Cost-sharing disproportionately affects people with chronic illnesses needing more care. Our qualitative study examined lived experiences navigating insurance benefits and treatment for bipolar disorder, which requires ongoing access to behavioral specialists and psychotropic medications., Methods: Forty semi-structured telephone interviews with individuals with bipolar disorder and employer-sponsored health insurance, or their family caregivers, explored health care needs, coverage details, out-of-pocket (OOP) costs, and perspectives on value. An iterative analytic approach identified salient themes., Results: Most individuals in our sample faced an annual insurance deductible, from $350-$10,000. OOP costs for specialist visits ranged from $0-$450 and for monthly psychotropic medications from $0-$1650. Acute episodes and care for comorbidities, including medication side effects, added to cost burdens. Medication nonadherence due to OOP costs was rare; respondents frequently pointed to the necessity of medications: "whatever it takes to get those"; "it's a life or death situation." Respondents also prioritized visits to psychiatrist prescribers, though visits were maximally spaced because of cost. Psychotherapy was often deemed unaffordable and forgone, despite perceived need. Interviewees cited limited networks and high out-of-network costs as barriers to specialists. Cost-sharing sometimes led to debt, skimping on nonbehavioral care or other necessities, exacerbated or prolonged mood symptoms, and stress at home., Limitations: Volunteer respondents may not fully represent the target population., Conclusions: Many people with bipolar disorder in US employer-sponsored plans experience undertreatment, hardship, and adverse health consequences due to high cost-sharing. More nuanced insurance benefit designs should accommodate the needs of individuals with complex conditions., (Copyright © 2020. Published by Elsevier B.V.)

Researchers increasingly recognize that stakeholder involvement enhances research relevance and validity. However, reports of patient engagement in research that relies on administrative records data are rare. The authors' collaborative project combined quantitative and qualitative studies of costs and access to care among U.S. adults with employer-sponsored insurance. The authors analyzed insurance claims to estimate the impacts on enrollee costs and utilization after patients with bipolar disorder were switched from traditional coverage to high-deductible health plans. In parallel, in-depth interviews explored people's experiences accessing treatment for bipolar disorder. Academic investigators on the research team partnered with the Depression and Bipolar Support Alliance (DBSA), a national advocacy organization for people with mood disorders. Detailed personal stories from DBSA-recruited volunteers informed and complemented the claims analyses. Several DBSA audience forums and a stakeholder advisor panel contributed regular feedback on study issues. These multiple engagement modes drew inputs of varying intensity from diverse community segments. Efforts to include new voices must acknowledge individuals' distinct interests and barriers to research participation. Strong engagement leadership roles ensure productive communication between researchers and stakeholders. The involvement of people with direct experience of care is especially necessary in research that uses secondary data. Longitudinal, adaptable partnerships enable colearning and higher-quality research that captures the manifold dimensions of patient experiences.

Purpose: There is limited evidence on the intensity of end-of-life (EOL) care for women < 65 years old, who account for about 40% of breast cancer deaths in the United States. Using established indicators, we estimated the intensity of EOL care among these women., Methods: We used 2000-2014 claims data from a large US insurer to identify women with metastatic breast cancer who, in the last month of their lives, had more than one hospital admission, emergency department visit, or an intensive care unit (ICU) admission and/or used antineoplastic therapy in the last 14 days of life. Using multivariate logistic regression, we assessed whether intensity of EOL care differed by demographic characteristics, socioeconomic factors, or regions., Results: Adjusted estimates show an increase in EOL ICU admissions between 2000-2003 and 2010-2014 from 14% (95% CI, 10% to 17%) to 23% (95% CI, 20% to 26%) and a small increase in emergency department visits from 10% (95% CI, 7% to 13%) to 12% (95% CI, 9% to 15%), both statistically significant. There was no statistically significant change in the proportions of women experiencing more than one EOL hospitalization (14% in 2010-2014; 95% CI, 11% to 17%) and of those receiving EOL antineoplastic treatment (24% in 2010-2014; 95% CI, 21% to 27%). Living in predominantly mixed, Hispanic, Black, or Asian neighborhoods correlated with more intense care (odds ratio, 1.39; 95% CI, 1.10 to 1.77 for ICU)., Conclusion: Consistent with findings in the Medicare population, our results suggest an overall increase in the number of ICU admissions at the EOL over time. They also suggest that patients from non-White neighborhoods receive more intense acute care.

Background: Hiatal hernias are often repaired concurrently with bariatric surgery to reduce risk of gastroesophageal reflux disease-related complications., Objectives: To examine the association between concurrent hiatal hernia repair (HHR) and bariatric outcomes., Setting: A 2010-2017 U.S. commercial insurance claims data set., Methods: We conducted a retrospective cohort study. We identified adults who underwent sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) alone or had bariatric surgery concurrently with HHR. We matched patients with and without HHR and followed patients up to 3 years for incident abdominal operative interventions, bariatric revisions/conversions, and endoscopy. Time to first event for each outcome was compared using multivariable Cox proportional hazards modeling., Results: We matched 1546 SG patients with HHR to 3170 SG patients without HHR, and we matched 457 RYGB patients with HHR to 1156 RYGB patients without HHR. A total of 73% had a full year of postoperative enrollment. Patients who underwent concurrent SG and HHR were more likely to have additional abdominal operations (adjusted hazard ratio [aHR], 2.1; 95% CI, 1.5-3.1) and endoscopies (aHR, 1.5; 95% CI, 1.2-1.8) but not bariatric revisions/conversions (aHR, 1.7; 95% CI, .6-4.6) by 1 year after surgery, a pattern maintained at 3 years of follow-up. Among RYGB patients, concurrent HHR was associated only with an increased risk of endoscopy (aHR, 1.4; 95% CI, 1.1-1.8)) at 1 year of follow-up, persisting at 3 years., Conclusions: Concurrent SG/HHR was associated with increased risk of some subsequent operative and nonoperative interventions, a pattern that was not consistently observed for RYGB. Additional studies could examine whether changes to concurrent HHR technique could reduce risk., (Copyright © 2020 American Society for Bariatric Surgery. Published by Elsevier Inc.

Background: Mail order pharmacy (MOP) use has been linked to improved medication adherence and health outcomes among patients with diabetes. However, no large-scale intervention studies have assessed the effect of encouraging MOP use on medication adherence., Objective: To assess an intervention to encourage MOP services to increase its use and medication adherence., Design: Randomized encouragement trial., Patients: 63,012 diabetes patients from three health care systems: Kaiser Permanente Northern California (KPNC), Kaiser Permanente Hawaii (KPHI), and Harvard Pilgrim Health Care (HPHC) who were poorly adherent to at least one class of cardiometabolic medications and had not used MOP in the prior 12 months., Intervention: Patients were randomized to receive either usual care (control arm) or outreach encouraging MOP use consisting of a mailed letter, secure email message, and automated telephone call outlining the potential benefits of MOP use (intervention arm). HPHC intervention patients received the letter only., Measurements: We compared the percentages of patients that began using MOP and that became adherent to cardiometabolic medication classes during a 12-month follow-up period. We also conducted a race/ethnicity-stratified analysis., Results: During follow-up, 10.6% of intervention patients began using MOP vs. 9.3% of controls (p < 0.01); the percent of cardiometabolic medication delivered via mail was 42.1% vs. 39.8% (p < 0.01). Metformin adherence improved in the intervention arm relative to control at the two KP sites (52% vs. 49%, p < 0.01). Stratified analyses suggested a significant positive effect of the intervention in White (RR: 1.12, 95% CI: 1.03, 1.22) and Asian (RR: 1.30, 95% CI: 1.17, 1.45) patients., Conclusion: This pragmatic trial showed that simple outreach to encourage MOP modestly increased its use and improved adherence measured by refills to a key class of diabetes medications in some settings. Given its minimal cost, clinicians and health systems should consider outreach interventions to actively promote MOP use among diabetes patients., Trial Registration: ClinicalTrials.gov registration number: NCT02621476.

Background: Supplemental breast cancer screening with breast magnetic resonance imaging (MRI) is recommended for women at high risk of breast cancer. To the authors' knowledge, recent national trends in breast MRI use are unknown., Methods: The authors used claims data from a large national insurer to calculate screening breast MRI rates from 2006 to 2016 in a US cohort of 10 million women aged 20 to 64 years. Use was stratified by subgroups of women with a BRCA mutation, family history of breast cancer, and prior breast cancer history and stratified by age. Joinpoint regression evaluated annual changes in trends., Results: The total sample included 37,447 screening breast MRI examinations in 25,617 women. Overall screening breast MRI rates were low and increased from 2.9 to 12.1 examinations per 10,000 women from 2006 to 2016. MRI use in women with a BRCA mutation increased by 21% on average annually from 210.8 per 10,000 women to 1562.0 per 10,000 women from 2006 to 2016. By 2016, women aged 50 to 64 years who had a BRCA mutation had the highest use of breast MRI (1669.6 MRI examinations per 10,000 women) compared with younger women (1198.4 MRI examinations per 10,000 women, 1519.1 MRI examinations per 10,000 women, and 1567.2 MRI examinations per 10,000 women, respectively, among women aged 20-29 years, 30-39 years, and 40-49 years). Women with a BRCA mutation comprised <1% of the current study population but received approximately 9% of screening breast MRI examinations. Breast MRI rates among women with a family history of breast cancer or prior breast cancer history initially increased from 2006 to 2008, but then stabilized or decreased., Conclusions: The increases in breast MRI use observed in the current study have indicated improvements in concordance with breast imaging guidelines. However, women with BRCA mutations remain underscreened, particularly younger women, thereby identifying a clear gap with which to enhance access., (© 2020 American Cancer Society.)

Background: Claims databases are generally considered inadequate for obesity research due to suboptimal capture of body mass index (BMI) measurements. This might not be true for bariatric surgery because of reimbursement requirements and changes in coding systems. We assessed the availability and validity of claims-based weight-related diagnosis codes among bariatric surgery patients., Methods: We identified three nested retrospective cohorts of adult bariatric surgery patients who underwent adjusted gastric banding, Roux-en-Y gastric bypass, or sleeve gastrectomy between January 1, 2011 and June 30, 2018 using different components of OptumLabs® Data Warehouse, which contains linked de-identified claims and electronic health records (EHRs). We measured the availability of claims-based weight-related diagnosis codes in the 6-month preoperative and 1-year postoperative periods in the main cohort identified in the claims data. We created two claims-based algorithms to classify the presence of severe obesity (a commonly used cohort selection criterion) and categorize BMI (a commonly used baseline confounder or postoperative outcome). We evaluated their performance by estimating sensitivity, specificity, positive predictive value, negative predictive value, and weighted kappa in two sub-cohorts using EHR-based BMI measurements as the reference., Results: Among the 29,357 eligible patients identified using claims only, 28,828 (98.2%) had preoperative weight-related diagnosis codes, either granular indicating BMI ranges or nonspecific denoting obesity status. Among the 27,407 patients with granular preoperative codes, 12,346 (45.0%) had granular codes and 9355 (34.1%) had nonspecific codes in the 1-year postoperative period. Among the 3045 patients with both preoperative claims-based diagnosis codes and EHR-based BMI measurements, the severe obesity classification algorithm had a sensitivity 100%, specificity 71%, positive predictive value 100%, and negative predictive value 78%. The BMI categorization algorithm had good validity categorizing the last available preoperative or postoperative BMI measurements (weighted kappa [95% confidence interval]: preoperative 0.78, [0.76, 0.79]; postoperative 0.84, [0.80, 0.87])., Conclusions: Claims-based weight-related diagnosis codes had excellent validity before and after bariatric surgical operation but suboptimal availability after operation. Claims databases can be used for bariatric surgery studies of non-weight-related effectiveness and safety outcomes that are well-captured.

Importance: Vitamin D deficiency is associated with chronic pain syndromes and higher opioid use among cancer patients, but its association with opioid use among opioid-naïve subjects following a major surgical procedure with acute pain has not been explored., Objective: To determine the association between serum 25-hydroxyvitamin D (25(OH)D) levels, opioid use, and opioid use disorder., Methods: We identified commercially insured subjects aged 18-64 years with available perioperative serum 25-hydroxyvitamin D (25D) levels who underwent one of nine major surgical procedures in 2000-2014. Primary outcomes were dose and duration of opioid use measured using pharmacy claims. Secondary outcome was opioid use disorder captured using diagnosis codes. Multivariable negative binomial models with generalized estimating equations were performed examining the association between 25D levels and postoperative opioid use measures, adjusting for age, sex, race/ethnicity, Charlson score, education, income, latitude, and season of blood draw. Adjusted Cox regression was used to examine the association with opioid use disorder., Results: Among 5446 subjects, serum 25(OH)D was sufficient (≥ 20 ng/mL) among 4349 (79.9%) subjects, whereas 837 (15.4%) had insufficient (12 to < 20 ng/mL) and 260 (4.8%) had deficient (< 12 ng/mL) levels. On multivariable analysis, as compared with subjects with sufficient 25(OH)D levels, subjects with deficient 25(OH)D levels had 1.7 more days (95% CI 0.76, 2.58) of opioid use per year and had 98.7 higher morphine milligram equivalent dose (95% CI 55.7, 141.8) per year. Among 11,713 study cohort, subjects with deficient 25(OH)D levels were more likely to be diagnosed with opioid use disorders (HR 2.41; 95% CI 1.05, 5.52)., Conclusion: Patients undergoing common surgical procedures with deficient 25D levels are more likely to have higher opioid use and an increased risk of opioid use disorder compared to those with sufficient levels. Serum 25D levels may serve as a biomarker to identify subjects at increased risk of opioid misuse.
