Medicare Enrollment and Spending Among Patients Initiating Dialysis After the Affordable Care Act.

Importance: Medicare finances health care for most US patients with end-stage kidney disease (ESKD), regardless of age. Medicare enrollment may have slowed for patients with incident ESKD who gained access to new private insurance options with the 2014 passage of the Affordable Care Act (ACA) and introduction of the ACA Marketplace.

Objective: To describe trends in public and private insurance coverage and dialysis spending among patients with incident ESKD from 2012 to 2017.

Integrating Out-of-Pocket Costs Into Shared Decision-Making for Heart Failure With Reduced Ejection Fraction: A Stepped-Wedge Trial (POCKET-COST-HF).

Background: Guideline-directed medical therapy for heart failure (HF) with reduced ejection fraction can entail high out-of-pocket (OOP) costs, prompting concerns about financial toxicity and access. OOP costs are generally unavailable during encounters. This trial assessed the impact of providing patient-specific OOP costs to patients and clinicians.

A comparison of time-varying propensity score vs sequential stratification approaches to longitudinal matching with a time-varying treatment.

Background: Methods for matching in longitudinal cohort studies, such as sequential stratification and time-varying propensity scores, facilitate causal inferences in the context of time-dependent treatments that are not randomized where patient eligibility or treatment status changes over time. The tradeoffs in available approaches have not been compared previously, so we compare two methods using simulations based on a retrospective cohort of patients eligible for weight loss surgery, some of whom received it.

Methods: This study compares matching completeness, bias, coverage, and precision among three approaches to longitudinal matching: (1) time-varying propensity scores (tvPS), (2) sequential stratification that matches exactly on all covariates used in tvPS (SS-Full) and (3) sequential stratification that exact matches on a subset of covariates (SS-Selected).

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.

Health Expenditures After Bariatric Surgery: A Retrospective Cohort Study.

Objective: To compare expenditures between surgical and matched nonsurgical patients in a retrospective cohort study.

Background: Bariatric surgery leads to substantial improvements in weight and weight-related conditions, but prior literature on postsurgical health expenditures is equivocal.

Methods: In a retrospective study, total outpatient, inpatient, and medication expenditures 3 years before and 5.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Medicare Enrollment Among Patients With End-Stage Kidney Disease Receiving Dialysis in Outpatient Facilities Between 2005 and 2016.

This study characterizes annual changes in enrollment of Medicare and non-Medicare patients treated at dialysis facilities before and after 2011 payment reforms and 2014 Affordable Care Act changes that influenced reimbursements.

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.

Short-Term VA Health Care Expenditures Following a Health Risk Assessment and Coaching Trial.

Background: Short-term health care costs following completion of health risk assessments and coaching programs in the VA have not been assessed.

Objective: To compare VA health care expenditures among veterans who participated in a behavioral intervention trial that randomized patients to complete a HRA followed by health coaching (HRA + coaching) or to complete the HRA without coaching (HRA-alone).

Design: Four-hundred seventeen veterans at three Veterans Affairs (VA) Medical Centers or Clinics were randomized to HRA + coaching or HRA-alone.

Trends in Peritoneal Dialysis Use in the United States after Medicare Payment Reform.

Background And Objectives: Peritoneal dialysis (PD) for ESKD is associated with similar mortality, higher quality of life, and lower costs compared with hemodialysis (HD), but has historically been underused. We assessed the effect of the 2011 Medicare prospective payment system (PPS) for dialysis on PD initiation, modality switches, and stable PD use.

Design, Setting, Participants, & Measurements: Using US Renal Data System and Medicare data, we identified all United States patients with ESKD initiating dialysis before (2006-2010) and after (2011-2013) PPS implementation, and observed their modality for up to 2 years after dialysis initiation.
