Changes in care associated with integrating Medicare and Medicaid for dual-eligible individuals.
This study’s objective was to evaluate changes in care associated with integrating Medicare and Medicaid coverage in a fully integrated dual-eligible special needs plan (FIDE-SNP) in Pennsylvania. This cohort study used a difference-in-differences analysis compared changes in care between 2 cohorts of dual-eligible individuals: (1) an integration cohort composed of Medicare Dual Eligible Special Needs Plan enrollees who joined a companion Medicaid plan following a 2018 state reform mandating Medicaid managed care (leading to integration), and (2) a comparison cohort with nonintegrated coverage before and after the start of Medicaid managed care. Analyses were conducted of outcomes in 4 domains: use of home- and community-based services (HCBS), care management and coordination, hospital stays and postacute care, and long-term nursing home stays. The study included 7967 individuals in the integration cohort and 3832 individuals in the comparison cohort. HCBS use increased differentially in the integration vs comparison cohorts by 0.61 days/person-month. However, integration was not associated with changes in care management and coordination, including medication use for chronic conditions (-0.02 fills/person-month) or follow-up outpatient care after a hospital stay (-0.01 visits/hospital stay). There was no significant difference in hospital stays between the cohorts.

The influence of payor status on outcomes associated with surgical repair of upper gastrointestinal perforations due to peptic ulcer disease in the United States.
An association between lack of insurance and inferior outcomes has been well described for a number of surgical emergencies, yet little is known about the relationship of payor status and outcomes of patients undergoing emergent surgical repair for upper gastrointestinal (UGI) perforations. In this study, the investigators evaluated the association of payor status and in-hospital mortality for patients undergoing emergency surgery for UGI perforations in the United States.

Association between postoperative pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery.
Postoperative pneumonia is the most common healthcare-associated infection in cardiac surgical patients, yet their impact across a 90-day episode of care remains unknown. The objective of this study was to examine the relationship between pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery. The investigators concluded that postoperative pneumonia was associated with significantly higher 90-day episode payments and inferior outcomes at the patient and hospital level.

Comparative effectiveness of uterine leiomyoma procedures using a large insurance claims database.
The objective of this retrospective analysis of administrative claims from a large U.S. commercial insurance database, was to compare risk of reintervention, long-term clinical outcomes, and health care utilization among women who have bulk symptoms from leiomyoma and who underwent the following procedures: hysterectomy, myomectomy, uterine artery embolization, and magnetic resonance-guided, focused ultrasound surgery.
