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.

Assessing the impact of service level when customer needs are uncertain: an empirical investigation of hospital step-down units.
In this study, the authors focused on estimating costs and benefits in a complex healthcare setting where the major differentiation among server types is the intensity of the service provided. They used data from ten hospitals and found that a step-down unit may be a cost-effective way to treat patients when used for those who are post-intensive care unit. However, they also found that the impact of step-down-unit care is more nuanced for patients admitted from the emergency department and may result in increased mortality risk and hospital length of stay for patients who should be treated in the intensive care unit. The authors recommended more study in this area.

Rising use of observation care among the commercially insured may lead to total and out-of-pocket cost savings.
Using multipayer commercial claims for the period 2009-13, the investigators evaluated utilization and spending among patients admitted for six conditions that are commonly managed with either observation care or short-stay hospitalizations. In their study period, the use of observation care increased relative to that of short-stay hospitalizations. In addition, total and out-of-pocket spending were substantially lower for observation care, though both grew rapidly--and at rates much higher than spending in the inpatient setting--over the study period.
