Association between hospital participation in Medicare Shared Savings Program Accountable Care Organizations and readmission following major surgery.
Accountable Care Organizations (ACOs) and readmission rates following major surgery. A retrospective cohort study was conducted using a 20% national Medicare sample to identify beneficiaries undergoing 1 of 7 common surgical procedures: abdominal aortic aneurysm repair, colectomy, cystectomy, prostatectomy, lung resection, total knee arthroplasty, and total hip arthroplasty between 2010 and 2014. Thirty-day risk-adjusted readmission rates was the primary outcome studied. Out of 2974 hospitals in the study, 389 were ACO affiliated. While rates fell for both cohorts, ACO hospitals had a higher decrease in hospitalizations over the same time period.

Revisit rates and associated costs after an emergency department encounter: a multistate analysis.
This study describes revisit rates, variation in revisit rates by diagnosis and state, and associated costs. It found that revisits after an index ED encounter are more frequent than previously reported, in part because many occur outside the index institution. Among ED patients in Florida, more resources are spent on revisits than on index ED visits.

Association of early post-discharge follow-up by a primary care physician and 30-day rehospitalization among older adults.
The researchers aimed to determine whether an office visit with a primary care physician within 7 days after discharge is associated with 30-day rehospitalization. Of 3,661 patients discharged to home during the study year, 1,808 received an office visit within 7 days and of these, 1,000 were with a primary care physician. No protective effect for office visits within 7 days was found.

Medicaid admissions and readmissions: understanding the prevalence, payment, and most common diagnoses.
The authors characterized acute care hospital admissions and thirty-day readmissions in the Medicaid population through a retrospective analysis in nineteen states. They found that Medicaid readmissions were both prevalent and costly, and that they represented 12.5 percent of Medicaid payments for all hospitalizations, with the most prevalent diagnostic categories being mental and behavioral disorders and diagnoses related to pregnancy, childbirth, and their complications.
