Physician and Hospital Performance in Medicare’s Updated Bundled-Payment Model for Joint Replacement
This cohort study found that participation in BPCI-A for joint replacement was associated with differentially lower total spending for both physicians and hospitals. Given that physicians in PGPs accounted for 73% of all the joint replacement episodes, these findings highlight the importance of facilitating alignment between hospitals and physicians in future bundled-payment models, including those that allow only hospitals
What motivates participants
Gamification and financial incentives both increased physical activity in the BE ACTIVE study, but results may be improved by tailoring interventions based on participants' personal traits and level of social support to optimize motivation.

Performance of Physician Groups and Hospitals Participating in Bundled Payments Among Medicare Beneficiaries
This cohort study and difference-in-differences analysis of PGPs and hospital participation in BPCI found that bundled payments were associated with cost savings for surgical episodes for PGPs, and savings for both surgical and medical episodes for hospitals. Policy makers should consider the comparative performance of participant types when designing and evaluating bundled payment models
Association of Patient Outcomes With Bundled Payments Among Hospitalized Patients Attributed to Accountable Care Organizations
In this cohort study, compared with inclusion in bundled payments alone, simultaneous inclusion in both ACOs and bundled payment programs was associated with lower institutional postacute care spending and readmissions for medical episodes and lower readmissions but not spending for surgical episodes. Receiving care under models such as ACOs may improve episode outcomes under bundled payments

Comparison of Pharmacy Claims and Electronic Pill Bottles for Measurement of Medication Adherence Among Myocardial Infarction Patients
BACKGROUND: Medication adherence after myocardial infarction remains low. Pharmacy claims have typically been used to measure medication adherence, but electronic pill bottles may offer additional information. OBJECTIVE: The main objectives of this study were to compare the association of adherence measured by prescription claims and remote monitoring technologies with cardiovascular events. RESEARCH DESIGN: This study was a secondary analysis of…
The Patient-centered Medical Home
BACKGROUND: The patient-centered medical home (PCMH) has increasingly been looked to by policy makers, health care providers, and private insurers as a potential solution to the fragmented and inefficient US health care system. Whether the PCMH achieves these goals is not known. OBJECTIVES: To evaluate a PCMH demonstration project implemented in 2011 in 8 New Jersey primary care practices covering over 10,000 plan members. RESEARCH DESIGN: We con…
A Randomized, Controlled Trial of Financial Incentives for Smoking Cessation
BACKGROUND: Smoking is the leading preventable cause of premature death in the United States. Previous studies of financial incentives for smoking cessation in work settings have not shown that such incentives have significant effects on cessation rates, but these studies have had limited power, and the incentives used may have been insufficient. METHODS: We randomly assigned 878 employees of a multinational company based in the United States to …
Effects of Resident Duty Hour Reform on Surgical and Procedural Patient Safety Indicators Among Hospitalized Veterans Health Administration and Medicare Patients
OBJECTIVE: Improving patient safety was a strong motivation behind duty hour regulations implemented by Accreditation Council for Graduate Medical Education on July 1, 2003. We investigated whether rates of patient safety indicators (PSIs) changed after these reforms. RESEARCH DESIGN: Observational study of patients admitted to Veterans Health Administration (VA) (N = 826,047) and Medicare (N = 13,367,273) acute-care hospitals from July 1, 2000 t…
Managed Care and Hospital Cost Containment
This study assesses the ability of managed care to contain hospital costs since the managed care backlash, using data from California's Office of Statewide Health Planning and Development for all acute-care hospitals in the state for the period 1991-2001. The analysis employs a long-differences design to examine cost growth before and after the managed care backlash. Results from the early 1990s are consistent with prior evidence that the combina…
Will Mandated Minimum Nurse Staffing Ratios Lead to Better Patient Outcomes
BACKGROUND: Mandatory hospital nurse staffing ratios are under consideration in a number of states without strong empirical evidence of the optimal ratio. OBJECTIVE: To determine whether increases in medical-surgical licensed nurse staffing levels are associated with improvements in patient outcomes for hospitals having different baseline staffing levels. RESEARCH DESIGN: Cross-sectional and fixed-effects regression analyses using a 1993-2001 pan…
Did Postoperative Mortality Increase After the Implementation of the Medicare Balanced Budget Act
BACKGROUND: The Balanced Budget Act (BBA) of 1997 was a cost-saving measure designed to reduce Medicare reimbursements by $116.4 billion from 1998 to 2002. Resulting financial strain could adversely affect the quality of patient care in hospitals. OBJECTIVE: We sought to determine whether 30-day mortality rates for surgical patients who developed complications changed at different rates in hospitals under different levels of financial strain from…
