Hospital Readmissions to Nonindex Hospitals: Patterns and Determinants Following the Medicare Readmission Reduction Penalty Program.

OBJECTIVE: To examine patterns and determinants of nonindex readmissions for Medicare as well as non-Medicare patients both before and immediately after the adoption of Medicare's Hospital Readmission Reduction Program (HRRP) in 2012. Nonindex readmissions are readmissions to hospitals that are different from the one from which the patient was discharged. METHODS: Observational analysis of statewide database from California comprising patient-level discharge reports. Mixed-effects logistic regression models examined the association between nonindex readmissions and both hospital- and patient-level characteristics. RESULTS: Nonindex readmissions for the population studied were approximately 25%, but the percentage of such readmissions was significantly higher for non-Medicare patients than those enrolled in Medicare. Nonindex readmissions were associated with several patient- and hospital-level characteristics from which patients were discharged. The adoption of the HRRP did not have any appreciable impact on the general pattern of nonindex readmissions. CONCLUSIONS: A substantial percentage of hospital readmissions are to nonindex hospitals, but the general pattern and determinants of these events have not changed following the adoption of the HRRP. As preventable readmissions continue to gain attention as a key quality indicator for hospital care, further investigations are needed to understand the potential value of nonindex readmissions as a quality indicator for hospital care.

Impact of ACA Medicaid Expansion on Hospitals' Financial Status.

EXECUTIVE SUMMARY: The Patient Protection and Affordable Care Act's insurance reforms were expected to have significant and positive implications for hospital finances. In particular, state expansion of Medicaid programs held the promise of reducing hospitals' uncompensated care costs as a result of expanding health insurance to many previously uninsured individuals. Recent research indicates that in the early phases of Medicaid expansion, many hospitals did experience a substantial decline in uncompensated care costs. However, studies to date have not considered whether Medicaid expansion resulted in payment shortfalls that offset some of what hospitals saved from lower uncompensated care costs. We examined filings submitted by hospitals to the Internal Revenue Service (IRS)-one of the few publicly available sources of national data on both uncompensated care costs and Medicaid payment shortfalls. We also compared changes in uncompensated care costs and Medicaid payment shortfalls for hospitals in expansion states with those in nonexpansion states. Our findings indicate that state expansion of Medicaid led to substantial reductions in hospitals' uncompensated care costs, but the savings were offset somewhat by increased Medicaid payment shortfalls. Therefore, studies that focus only on reductions in uncompensated care costs can overstate the benefits of Medicaid expansion on hospitals finances.

Magnitude and financial implications of inappropriate diagnostic imaging for three common clinical conditions.

OBJECTIVE: To quantify the level of adherence to imaging guidelines for three common clinical indications for a commercially insured population. DESIGN: Retrospective analysis of administrative claims data for commercially insured individuals with diagnostic imaging claims (MRI and X-ray) for either uncomplicated low back pain, non-traumatic knee pain or non-traumatic shoulder pain. SETTING: The State of Massachusetts for 2010 and 2013. PARTICIPANTS: Adults with no chronic conditions and without evidence of prior management in the 12 months preceding to the initial office visit for each of the clinical indications. MAIN OUTCOMES MEASURES: Imaging procedures performed within 30 days of the initial office visit were classified as appropriate or inappropriate according to adherence to imaging guidelines from American College of Radiology. RESULTS: More than 60% of lumbar spine MRI's were deemed inappropriate in 2010 and in 2013. Over 30% of MRI's for shoulder pain and knee pain were inappropriate in 2010 and in 2013. Patients age 18-59 with inappropriate imaging claims had significantly lower rates of surgical procedures within 90 days of imaging than those with appropriate imaging. Inappropriate imaging accounted for over 20% of annual imaging costs for the three clinical indications. CONCLUSIONS: Reducing inappropriate imaging procedures can lead to substantial savings through the elimination of unnecessary and low value procedures. Increased awareness of and adherence to best practice guidelines should be a focus of efforts to cut waste in our healthcare system.

Community Benefit Spending By Tax-Exempt Hospitals Changed Little After ACA.

Provisions of the Affordable Care Act (ACA) encouraged tax-exempt hospitals to invest broadly in community health benefits. Four years after the ACA's enactment, hospitals had increased their average spending for all community benefits by 0.5 percentage point, from 7.6 percent of their operating expenses in 2010 to 8.1 percent in 2014.

Usual Course of Treatment and Predictors of Treatment Utilization for Patients With Posttraumatic Stress Disorder.

OBJECTIVE: Posttraumatic stress disorder (PTSD) is a debilitating psychiatric illness that frequently remains undiagnosed and untreated. While extensive research has been conducted among veterans, little research has evaluated course of treatment for PTSD in a general hospital setting. METHODS: We utilized data from the Partners HealthCare Research Patient Data Registry to evaluate mental health treatment utilization, including psychotherapy and pharmacotherapy, by patients with recently diagnosed primary PTSD following DSM-IV criteria between January 1, 2002, and June 30, 2011. We additionally evaluated predictors of treatment utilization 6 months postdiagnosis. RESULTS: Among 2,475 patients with recently diagnosed primary PTSD, approximately half (55.7%) had any therapy visit and 10% had at least 12 therapy visits in the 6 months following diagnosis. Approximately half (47.0%) received a psychiatric prescription, with 29.3% receiving a selective serotonin reuptake inhibitor (SSRI), 11.8% receiving an atypical antipsychotic, and 24.4% receiving a benzodiazepine. Latinos were 25% (95% CL = 1.09, 1.43) more likely to have an SSRI prescription, 35% (95% CL = 1.05, 1.75) more likely to have an atypical antipsychotic prescription, and 28% (95% CL = 1.19, 1.38) more likely to receive any psychotherapy. Women were 49% (95% CL = 0.42, 0.63) less likely to have an atypical antipsychotic prescription. Patients with Medicare were 23% (95% CL = 0.67, 0.88) less likely to have any psychotherapy, and patients with Medicaid were 35% (95% CL = 0.46, 0.92) less likely to have 12 or more therapy visits. CONCLUSIONS: Many patients with a primary diagnosis of PTSD do not receive psychotherapy, and psychiatric prescriptions, including atypical antipsychotics and benzodiazepines, are common. Future research is needed to determine the quality of care received and explore subpopulation-specific barriers limiting access to care.

Residential segregation and mental health among Latinos in a nationally representative survey.

BACKGROUND: Among Latinos, living in a locality with greater Latino ethnic density may be protective for mental health, although findings vary by Latino subgroup, gender and birthplace. Although little studied, Latino residential segregation may capture different pathways linking risk and protective environmental factors to mental health than local ethnic density. METHODS: This study evaluated the association between residential segregation and mental distress as measured by the Kessler-10 (K10) among Latino participants in the National Latino and Asian American Study (NLAAS). Census data from 2000 was used to calculate metropolitan statistical area (MSA) residential segregation using the dissimilarity and isolation indices, as well as census tract ethnicity density and poverty. Latino subgroup (Puerto Rican, Mexican American, Cuban American and other Latino subgroup), gender and generation status were evaluated as moderators. RESULTS: Among 2554 Latino participants in NLAAS, residential segregation as measured by the isolation index was associated with less mental distress (ß -0.14, 95% CI -0.26 to -0.03 log(K10)) among Latinos overall after adjustment for ethnic density, poverty and individual covariates. Residential segregation as measured by the dissimilarity index was significantly associated with less mental distress among men (ß -0.56, 95% CI -1.04 to -0.08) but not among women (ß -0.20, 95% CI -0.45 to 0.04, p-interaction=0.019). No modification was observed by Latino subgroup or generation. CONCLUSIONS: Among Latinos, increasing residential segregation was associated with less mental distress, and this association was moderated by gender. Findings suggest that MSA-level segregation measures may capture protective effects associated with living in Latino communities for mental health.
