To further understand documented associations between obesity and urban sprawl, this research describes individuals' trade-offs between health-related activities and commuting time. A cross-section of 24,861 working-age individuals employed full-time and residing in urban counties is constructed from the American Time Use Survey (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010). Data are analyzed using seemingly unrelated regressions to quantify health-related activity decreases in response to additional time spent commuting. Outcomes are total daily minutes spent in physical activity at a moderate or greater intensity, preparing food, eating meals with family, and sleeping. Commuting time is measured as all travel time between home and work and vice versa. The mean commuting time is 62 min daily, the median is 55 min, and 10.1% of workers commute 120 min or more. Spending an additional 60 min daily commuting above average is associated with a 6% decrease in aggregate healthrelated activities and spending an additional 120 min is associated with a 12% decrease. The greatest percentage of commuting time comes from sleeping time reductions (28-35%). Additionally, larger proportions of commuting time are taken from physical activity and food preparation relative to the mean commuting length: of 60 min spent commuting, 16.1% is taken from physical activity and 4.1% is taken from food preparation; of 120 min commuting, 20.3% is taken from physical activity and 5.6% is taken from food preparation. The results indicate that longer commutes are associated with behavioral patterns which over time may contribute to obesity and other poor health outcomes. These findings will assist both urban planners and researchers wishing to understand time constraints' impacts on health.
Key PointsQuestionWas the Centers for Medicare & Medicaid Services Oncology Care Model (OCM), an alternative payment model for cancer patients undergoing chemotherapy, associated with differences in Medicare spending, utilization, quality, and patient experience over the model’s first 3 years?FindingsIn this exploratory difference-in-differences study of Medicare fee-for-service beneficiaries with cancer undergoing chemotherapy (483 310 beneficiaries with 987 332 episodes treated at 201 OCM participating practices and 557 354 beneficiaries with 1 122 597 episodes treated at 534 comparison practices), OCM was associated with a statistically significant relative decrease in total episode payments of $297 that was not sufficient to cover the costs of care coordination or performance-based payments. There were no statistically significant differences in most measures of utilization, quality, or patient experiences.MeaningIn its first 3 years, the OCM was significantly associated with modestly lower Medicare episode payments that did not offset model payments to participating practices, and there were no significant differences in most utilization, quality, or patient experience outcomes.
Background Post-acute care (PAC) rehabilitation aims to maximize independence and facilitate a safe community transition. Yet little is known about PAC patients’ success in staying home post-discharge or differences on this outcome across PAC providers. Objectives Examine the percentage of PAC patients who remain in the community at least 30 days after discharge (i.e., successful community discharge) following hip fracture rehabilitation and describe differences among PAC facilities based on this outcome. Research Design Retrospective observational study. Subjects Community-dwelling, Medicare fee-for-service beneficiaries 75 years of age and older who experienced their first hip fracture between 1999–2007 (n=880,779). PAC facilities admitting hip fracture patients in 2006. Measures Successful community discharge, sites of readmission after PAC discharge. Results Between 1999 and 2007, 57% of patients achieved successful community discharge. Black were less likely (adjusted odds ratios=0.84, 95% confidence interval 0.82–0.86) than similar whites to achieve successful community discharge. Among all who re-entered the community (n=581,095), 14% remained in the community fewer than 30 days. Acute hospitals (67.5%) and institutional PAC (16.8%) were the most common sites of re-entry. The median proportion of successful community discharge among facilities was 49% (IQR: 33%–66%). Lowest-quartile facilities admitted older (85.9 vs. 84.1 years of age), sicker patients (e.g., higher rates of hospital complications 6.0% vs. 4.6%), but admitted fewer annually (7.1 vs. 19.3), compared to the highest quartile. Conclusions Re-entry into the healthcare system after PAC community discharge is common. Due to the distinct care needs of the PAC population there is a need for a quality measure that complements the current 30-day hospital readmission outcome and captures the objectives of PAC rehabilitation.
