Impact of comprehensive medication reviews on potentially inappropriate medication discontinuation in Medicare beneficiaries.

BACKGROUND: The use of potentially inappropriate medications (PIMs) is associated with increased risk of hospitalizations and emergency room visits and varies by racial and ethnic subgroups. Medicare's nationwide medication therapy management (MTM) program requires that Part D plans offer an annual comprehensive medication review (CMR) to all beneficiaries who qualify, and provides a platform to reduce PIM use. The objective of this study was to assess the impact of CMR on PIM discontinuation in Medicare beneficiaries and whether this differed by race or ethnicity. METHODS: Retrospective cohort study of community-dwelling Medicare Part D beneficiaries ≥66 years of age who were eligible for MTM from 2013 to 2019 based on 5% Medicare fee-for-service claims data linked to the 100% MTM data file. Among those using a PIM, MTM-eligible CMR recipients were matched to non-recipients via sequential stratification. The probability of PIM discontinuation was estimated using regression models that pooled yearly subcohorts accounting for within-beneficiary correlations. The most common PIMs that were discontinued after CMR were reported. RESULTS: We matched 24,368 CMR recipients to 24,368 CMR non-recipients during the observation period. Median age was 74-75, 35% were males, most were White beneficiaries (86%-87%), and the median number of PIMs was 1. In adjusted analyses, CMR receipt was positively associated with PIM discontinuation (adjusted relative risk [aRR]: 1.26, 95% CI: 1.20-1.32). There was no evidence of differential impact of CMR by race or ethnicity. The PIMs most commonly discontinued after CMR were glimepiride, zolpidem, digoxin, amitriptyline, and nitrofurantoin. CONCLUSIONS: Among Medicare beneficiaries who are using a PIM, CMR receipt was associated with PIM discontinuation, suggesting that greater CMR use could facilitate PIM reduction for all racial and ethnic groups.

Comprehensive Medication Review Completion Rates and Disparities After Medicare Star Rating Measure.

Importance: Comprehensive medication reviews (CMRs) are offered to qualifying US Medicare beneficiaries annually to optimize medication regimens and therapeutic outcomes. In 2016, Medicare adopted CMR completion as a Star Rating quality measure to encourage the use of CMRs. Objective: To examine trends in CMR completion rates before and after 2016 and whether racial, ethnic, and socioeconomic disparities in CMR completion changed. Design, Setting, and Participants: This observational study using interrupted time-series analysis examined 2013 to 2020 annual cohorts of community-dwelling Medicare beneficiaries aged 66 years and older eligible for a CMR as determined by Part D plans and by objective minimum eligibility criteria. Data analysis was conducted from September 2022 to February 2024. Exposure: Adoption of CMR completion as a Star Rating quality measure in 2016. Main Outcome and Measures: CMR completion modeled via generalized estimating equations. Results: The study included a total of 561 950 eligible beneficiaries, with 253 561 in the 2013 to 2015 cohort (median [IQR] age, 75.8 [70.7-82.1] years; 90 778 male [35.8%]; 6795 Asian [2.7%]; 24 425 Black [9.6%]; 7674 Hispanic [3.0%]; 208 621 White [82.3%]) and 308 389 in the 2016 to 2020 cohort (median [IQR] age, 75.1 [70.4-80.9] years; 126 730 male [41.1%]; 8922 Asian [2.9%]; 27 915 Black [9.1%]; 7635 Hispanic [2.5%]; 252 781 White [82.0%]). The unadjusted CMR completion rate increased from 10.2% (7379 of 72 225 individuals) in 2013 to 15.6% (14 185 of 90 847 individuals) in 2015 and increased further to 35.8% (18 376 of 51 386 individuals) in 2020, in part because the population deemed by Part D plans to be MTM-eligible decreased by nearly half after 2015 (90 487 individuals in 2015 to 51 386 individuals in 2020). Among a simulated cohort based on Medicare minimum eligibility thresholds, the unadjusted CMR completion rate increased but to a lesser extent, from 4.4% in 2013 to 12.6% in 2020. Compared with White beneficiaries, Asian and Hispanic beneficiaries experienced greater increases in likelihood of CMR completion after 2016 but remained less likely to complete a CMR. Dual-Medicaid enrollees also experienced greater increases in likelihood of CMR completion as compared with those without either designation, but still remained less likely to complete CMR. Conclusion and Relevance: This study found that adoption of CMR completion as a Star Rating quality measure was associated with higher CMR completion rates. The increase in CMR completion rates was achieved partly because Part D plans used stricter eligibility criteria to define eligible patients. Reductions in disparities for eligible Asian, Hispanic, and dual-Medicaid enrollees were seen, but not eliminated. These findings suggest that quality measures can inform plan behavior and could be used to help address disparities.

Health Expenditures After Bariatric Surgery: A Retrospective Cohort Study.

OBJECTIVE: Bariatric surgery leads to substantial improvements in weight and weight-related conditions, but prior literature on post-surgical health expenditures is equivocal. In a retrospective cohort study, we compared expenditures between surgical and matched non-surgical patients. SUMMARY BACKGROUND DATA AND METHODS: In a retrospective study, total, outpatient, inpatient and medication expenditures 3 years before and 5.5 years after surgery were compared between 22,698 bariatric surgery (n=7,127 RYGB, 15,571 sleeve gastrectomy) patients from 2012-2019 and 66,769 matched non-surgical patients, using generalized estimating equations. We also compared expenditures between patients receiving the two leading surgical procedures in weighted analyses. RESULTS: Surgical and non-surgical cohorts were well matched, 80-81% female, with mean body mass index (BMI) of 44, and mean age of 47 (RYGB) and 44 (SG) years. Estimated total expenditures were similar between surgical and non-surgical groups 3 years before surgery ($27 difference, 95% confidence interval (CI): -42, 102)), increased 6 months prior to surgery for surgical patients, and decreased below pre-period levels for both groups after 3-5.5 years to become similar (difference at 5.5 y=-$61, 95% CI: -166, 52). Long-term outpatient expenditures were similar between groups. Surgical patients' lower long-term medication expenditures ($314 lower at 5.5 y, 95% CI: -419, -208) were offset by a higher risk of hospitalization. Total expenditures were similar between RYGB and SG patients 3.5 to 5.5 years after surgery. CONCLUSIONS: Bariatric surgery translated into lower medication expenditures than matched controls, but not lower overall long-term expenditures. Expenditure trends appear similar for the two leading bariatric operations.

Effectiveness and safety of drugs for obesity.

Recent publicity around the use of new antiobesity medications (AOMs) has focused the attention of patients and healthcare providers on the role of pharmacotherapy in the treatment of obesity. Newer drug treatments have shown greater efficacy and safety compared with older drug treatments, yet access to these drug treatments is limited by providers' discomfort in prescribing, bias, and stigma around obesity, as well as by the lack of insurance coverage. Now more than ever, healthcare providers must be able to discuss the risks and benefits of the full range of antiobesity medications available to patients, and to incorporate both guideline based advice and emerging real world clinical evidence into daily clinical practice. The tremendous variability in response to antiobesity medications means that clinicians need to use a flexible approach that takes advantage of specific features of the antiobesity medication selected to provide the best option for individual patients. Future research is needed on how best to use available drug treatments in real world practice settings, the potential role of combination therapies, and the cost effectiveness of antiobesity medications. Several new drug treatments are being evaluated in ongoing clinical trials, suggesting that the future for pharmacotherapy of obesity is bright.

Eliminating Health Disparities in Atrial Fibrillation, Heart Failure, and Dyslipidemia: A Path Toward Achieving Pharmacoequity.

PURPOSE OF REVIEW: Pharmacoequity refers to the goal of ensuring that all patients have access to high-quality medications, regardless of their race, ethnicity, gender, or other characteristics. The goal of this article is to review current evidence on disparities in access to cardiovascular drug therapies across sociodemographic subgroups, with a focus on heart failure, atrial fibrillation, and dyslipidemia. RECENT FINDINGS: Considerable and consistent disparities to life-prolonging heart failure, atrial fibrillation, and dyslipidemia medications exist in clinical trial representation, access to specialist care, prescription of guideline-based therapy, drug affordability, and pharmacy accessibility across racial, ethnic, gender, and other sociodemographic subgroups. Researchers, health systems, and policy makers can take steps to improve pharmacoequity by diversifying clinical trial enrollment, increasing access to inpatient and outpatient cardiology care, nudging clinicians to increase prescription of guideline-directed medical therapy, and pursuing system-level reforms to improve drug access and affordability.

Clinician Response to Patient Medication Prices Displayed in the Electronic Health Record.

This cross-sectional study examines whether clinicians changed their medication orders after seeing the patient's out-of-pocket drug costs in the electronic health record.

Rates of Medicare Enrollment Among Dialysis Patients After Implementation of Medicare Payment Reform and the Affordable Care Act Marketplace.

Importance: Medicare finances health care for most US patients with end-stage kidney disease (ESKD), regardless of age. The 2011 Medicare prospective payment system (PPS) for dialysis reduced reimbursement for hemodialysis, and the 2014 Patient Protection and Affordable Care Act (ACA) Marketplace increased patient access to new private insurance options, potentially influencing organizations that provide health care, such as hospitals, nursing homes, and dialysis facilities, to adjust their payer mix away from Medicare sources. Objective: To describe Medicare enrollment trends among patients with incident ESKD in 2006 to 2016. Design, Setting, and Participants: This retrospective cohort study involved US patients aged 18 to 64 years who were not enrolled in Medicare at dialysis initiation in 2006 to 2016, with 1-year follow-up through 2017. Data analysis was conducted April 2021 to June 2022. Exposures: The exposure of interest was a 3-category indicator of time, whether patients initiated dialysis before policies were enacted (2006-2010), in the first years of the Medicare ESKD PPS (2011-2013), or during the Medicare ESKD PPS and implementation of the ACA Marketplace (2014-2016). Main Outcomes and Measures: Patient-level Medicare enrollment through the first year of dialysis. Logistic regression and Cox models were used to examine associations of time, patient characteristics, and Medicare enrollment, adjusting for patient demographic, clinical, and market-level characteristics. Results: Of 335 157 patients aged 18 to 64 years with ESKD not actively enrolled in Medicare when they initiated dialysis in 2006 to 2016, the mean (SD) age was 49.9 (10.8) years, 198 164 (59.1%) were men, 188 290 (56.2%) were White, and 313 622 (93.6%) received in-center hemodialysis. New Medicare enrollment was higher in 2006 to 2010 (110 582 patients [73.1%]) than after the Medicare ESKD PPS and ACA Marketplace in 2014 to 2016 (55 382 patients [58.5%]). In adjusted analyses, declining Medicare enrollment was associated with implementation of 2011 Medicare ESKD PPS and 2014 ACA policies and was disproportionately lower among younger, racially minoritized, and ethnically Hispanic patients. Conclusions and Relevance: There was declining Medicare enrollment among new dialysis patients associated with the 2011 Medicare ESKD PPS and 2014 ACA Marketplace that raise concerns about benefits and harms to patients and payers and continued disparities in kidney care. As the dialysis payer mix moves toward higher proportions of patients not covered by Medicare, it will be important to understand the implications for health care system and patient outcomes.

How can healthcare organizations improve cost-of-care conversations? A qualitative exploration of clinicians' perspectives.

OBJECTIVES: Clinicians increasingly believe they should discuss costs with their patients. We aimed to learn what strategies clinicians, clinic leaders, and health systems can use to facilitate vital cost-of-care conversations. METHODS: We conducted focus groups and semi-structured interviews with outpatient clinicians at two US academic medical centers. Clinicians recalled previous cost conversations and described strategies that they, their clinic, or their health system could use to facilitate cost conversations. Independent coders recorded, transcribed, and coded focus groups and interviews. RESULTS: Twenty-six clinicians participated between December 2019 and July 2020: general internists (23%), neurologists (27%), oncologists (15%), and rheumatologists (35%). Clinicians proposed the following strategies: teach clinicians to initiate cost conversations; systematically collect financial distress information; partner with patients to identify costs; provide accurate insurance coverage and/or out-of-pocket cost information via the electronic health record; develop local lists of lowest-cost pharmacies, laboratories, and subspecialists; hire financial counselors; and reduce indirect costs (e.g., parking). CONCLUSIONS: Despite considerable barriers to discussing, identifying, and reducing patient costs, clinicians described a variety of strategies for improving cost communication in the clinic. PRACTICE IMPLICATIONS: Health systems and clinic leadership can and should implement these strategies to improve the financial health of the patients they serve.

Accuracy of Physician Estimates of Out-of-Pocket Costs for Medication Filling.

Importance: One-third of US residents have trouble paying their medical bills. They often turn to their physicians for help navigating health costs and insurance coverage. Objective: To determine whether physicians can accurately estimate out-of-pocket expenses when they are given all of the necessary information about a drug's price and a patient's insurance plan. Design, Setting, and Participants: This national mail-in survey used a random sample of US physicians. The survey was sent to 900 outpatient physicians (300 each of primary care, gastroenterology, and rheumatology). Physicians were excluded if they were in training, worked primarily for the Veterans Administration or Indian Health Service, were retired, or reported 0% outpatient clinical effort. Analyses were performed from July to December 2020. Main Outcomes and Measures: In a hypothetical vignette, a patient was prescribed a new drug costing $1000/month without insurance. A summary of her private insurance information was provided, including the plan's deductible, coinsurance rates, copays, and out-of-pocket maximum. Physicians were asked to estimate the drug's out-of-pocket cost at 4 time points between January and December, using the plan's 4 types of cost-sharing: (1) deductibles, (2) coinsurance, (3) copays, and (4) out-of-pocket maximums. Multivariate linear regression was used to assess differences in performance by specialty, adjusting for attitudes toward cost conversations, demographics, and clinical characteristics. Results: The response rate was 45% (405 of 900) and 371 respondents met inclusion criteria. Among the respondents included in this study, 59% (n = 220) identified as male, 23% (n = 84) as Asian, 3% (n = 12) as Black, 6% (n = 24) as Hispanic, and 58% (n = 216) as White; 30% (n = 112) were primary care physicians, 35% (n = 128) were gastroenterologists, and 35% (n = 131) were rheumatologists; and the mean (SD) age was 49 (10) years. Overall, 52% of physicians (n = 192) accurately estimated costs before the deductible was met, 62% (n = 228) accurately used coinsurance information, 61% (n = 224) accurately used copay information, and 57% (n = 210) accurately estimated costs once the out-of-pocket maximum was met. Only 21% (n = 78) of physicians answered all 4 questions correctly. Ability to estimate out-of-pocket costs was not associated with specialty, attitudes toward cost conversations, or clinic characteristics. Conclusions and Relevance: This survey study found that many US physicians have difficulty estimating out-of-pocket costs, even when they have access to their patients' insurance plans. The mechanics involved in calculating real-time out-of-pocket costs are complex. These findings suggest that increased price transparency and simpler insurance cost-sharing mechanisms are needed to enable informed cost conversations at the point of prescribing.

Trends in Dialysis Industry Consolidation After Medicare Payment Reform, 2006-2016.

Importance: The dialysis industry is highly concentrated, with large dialysis organizations now providing dialysis for more than 85% of patients with kidney failure in the United States. In 2011, Medicare introduced a new Prospective Payment System (PPS) for end-stage kidney disease, which bundled payment for dialysis care into 1 payment per patient. Trends in dialysis facility consolidation after the PPS went into effect are unknown. Objective: To determine whether the introduction of the PPS in 2011 was associated with an acceleration in acquisitions and closures of small dialysis chains (<20 facilities) and independently owned facilities. Design Setting and Participants: This retrospective cohort study included all Medicare-certified independent or small chain-affiliated dialysis facilities in the continental US between 2006 and 2016. Data were obtained from Medicare and the US Renal Data System and were analyzed in 2020. Exposures: The PPS. Main Outcomes and Measures: Discrete time hazard models were used to estimate the odds of acquisition and closure before the PPS (2006-2010) vs after the PPS (2011-2016). Analyses controlled for facility, market, and regional demographic characteristics. The average predicted marginal probabilities of acquisition and closure over time were estimated. Results: The proportion of small chain-affiliated and independently owned facilities declined from 29% (1383 of 4750 facilities) in 2006 to 15% (1038 of 6738) in 2016. Among 13 481 facility-years, 6352 (47%) were for profit, and mean (SD) census was 68 (59) patients. Overall, 3286 (24%) facilities opened during the observation period. The proportion of acquisitions that occurred each year varied from 1.1% (12 of 1065 facilities in 2015) to 7.2% (86 of 1192 facilities in 2012), while closures varied from 0.8% (9 of 1065 facilities in 2015) to 2.2% (28 of 1286 facilities in 2010), making both fairly rare. There was a 3.48 higher odds of acquisition in the post-PPS period compared with the pre-PPS period (95% CI, 1.62-7.47; P = .001). The odds of closure before and after the PPS were not statistically significantly different (odds ratio, 2.03; 95% CI, 0.61-6.73; P = .25). Facilities that opened during the observation period had a 7.2% higher predicted probability of acquisition compared with older facilities (95% CI, 5.4%-9.0%; P < .001). Conclusions and Relevance: In this cohort study of continental US Medicare-certified dialysis facilities, small-chain and independently owned facilities retained a declining share of the dialysis market. Further research should evaluate the effect of continued dialysis market consolidation on patient access, health care utilization, and clinical outcomes.

Trends in Regional Supply of Peritoneal Dialysis in an Era of Health Reform, 2006 to 2013.

Peritoneal dialysis (PD), a home-based treatment for kidney failure, is associated with similar mortality, higher quality of life, and lower costs compared with hemodialysis. Yet <10% of patients receive PD. Access to this alternative treatment, vis-à-vis providers' supply of PD services, may be an important factor but has been sparsely studied in the current era of national payment reform for dialysis care. We describe temporal and regional variation in PD supply among Medicare-certified dialysis facilities from 2006 to 2013. The average proportion of facilities offering PD per hospital referral region increased from 40% (2006) to 43% (2013). PD supply was highest in hospital referral regions with higher percentage of facilities in urban areas (p = .004), prevalence of PD use (p < .0001), percentage of White end-stage renal disease patients (p = .02), and per capita income (p = .02). Disparities in PD access persist in rural, non-White, and low-income regions. Policy efforts to further increase regional PD supply should focus on these underserved communities.

Comparing Mortality of Peritoneal and Hemodialysis Patients in an Era of Medicare Payment Reform.

BACKGROUND: Prior studies have shown peritoneal dialysis (PD) patients to have lower or equivalent mortality to patients who receive in-center hemodialysis (HD). Medicare's 2011 bundled dialysis prospective payment system encouraged expansion of home-based PD with unclear impacts on patient outcomes. This paper revisits the comparative risk of mortality between HD and PD among patients with incident end-stage kidney disease initiating dialysis in 2006-2013. RESEARCH DESIGN: We conducted a retrospective cohort study comparing 2-year all-cause mortality among patients with incident end-stage kidney disease initiating dialysis via HD and PD in 2006-2013, using data from the US Renal Data System and Medicare. Analysis was conducted using Cox proportional hazards models fit with inverse probability of treatment weighting that adjusted for measured patient demographic and clinical characteristics and dialysis market characteristics. RESULTS: Of the 449,652 patients starting dialysis between 2006 and 2013, the rate of PD use in the first 90 days increased from 9.3% of incident patients in 2006 to 14.2% in 2013. Crude 2-year mortality was 27.6% for patients dialyzing via HD and 16.7% for patients on PD. In adjusted models, there was no evidence of mortality differences between PD and HD before and after bundled payment (hazard ratio, 0.96; 95% confidence interval, 0.89-1.04; P=0.33). CONCLUSIONS: Overall mortality for HD and PD use was similar and mortality differences between modalities did not change before versus after the 2011 Medicare dialysis bundled payment, suggesting that increased use of home-based PD did not adversely impact patient outcomes.

Resident Physician Experiences With and Responses to Biased Patients.

Importance: Biased patient behavior negatively impacts resident well-being. Data on the prevalence and frequency of these encounters are lacking and are needed to guide the creation of institutional trainings and policies to support trainees. Objective: To evaluate the frequency of resident experiences with and responses to a range of biased patient behaviors. Design, Setting, and Participants: A retrospective survey was sent via email to 331 second- and third-year internal medicine residents from 3 academic medical centers in California and North Carolina. First-year residents were excluded owing to their limited interactions with patients at the time of participant recruitment. Data were collected from August 21 to November 25, 2019. Main Outcomes and Measures: Descriptive statistics were used to report the frequency of experience of various types of biased patient behavior, residents' responses, the factors impeding residents' responses, and residents' experiences and beliefs regarding training and policies. Results: Overall, 232 of 331 residents (70%) participated; 116 (50%) were women; 116 of 247 (47%) were White (participants had the option of selecting >1 race/ethnicity); and 23 (10%) identified as lesbian, gay, bisexual, transgender, or queer. The frequency of resident-reported experience of types of biased patient behaviors varied. The most common behaviors-belittling comments and assumption of nonphysician status-were reported to be experienced 1 or more times per week by 14% of residents (32 of 231) and 17% of residents (38 of 230), respectively. Women, Black or Latinx, and Asian residents reported experiencing biased behavior more frequently. Forty-five percent of Black or Latinx residents (17 of 38) encountered instances of explicit epithets or rejection of care. All 70 Asian residents reported experiencing inquiries into their ethnic origins. Most women residents (110 of 115 [96%]) experienced role questioning behaviors, and 87% (100 of 115) experienced sexual harassment. The need to prioritize clinical care and a sense of futility in responding were the most common factors (cited by 34% of residents [76 of 227] and 25% of residents [56 of 227], respectively) significantly impeding responses to biased behaviors. Eighty-five percent of residents (191 of 226) never reported incidents to their institution. Eighty-nine percent of residents (206 of 232) identified training and policies as necessary or very necessary. Conclusions and Relevance: This survey study suggests that biased patient behavior is experienced frequently by internal medicine residents. Non-White and women residents reported experiencing a disproportionate burden of these incidents. Residents' responses rarely included institutional involvement. Residency programs and health care systems should prioritize training and policies to address biased patient behavior and support affected residents.

Fragmentation of care as a barrier to optimal ESKD management.

Caring for patients with end-stage kidney disease (ESKD) in the United States is challenging, due in part to the complex epidemiology of the disease's progression as well as the ways in which care is delivered. As CKD progresses toward ESKD, the number of comorbidities increases and care involves multiple healthcare providers from multiple subspecialties. This occurs in the context of a fragmented US healthcare delivery system that is traditionally siloed by provider specialty, organization, as well as systems of payment and administration. This article describes the role of care fragmentation in the delivery of optimal ESKD care and identifies research gaps in the evidence across the continuum of care. We then consider the impact of care fragmentation on ESKD care from the patient and health system perspectives and explore opportunities for system-level interventions aimed at improving care for patients with ESKD.
