A primer on cost-effectiveness in the allergy clinic.
This paper examines ways to incorporate cost-effectiveness into care at allergy clinics. The article discusses in general terms how to use cost-effective analyses (CEA) to grade health outcomes and economic benefits. The authors state that future research is needed to provide a better understanding of variation across population health state utilities for allergic conditions and to more accurately reflect quality adjusted life years for patients with allergies.

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.

Reference pricing: the case of screening colonoscopies.
In this study, the investigators studied the introduction of reference pricing to the California Public Employees' Retirement System. The investigators found a 10 percentage point increase in the share of patients using an ambulatory surgery center (ASC), leading to a $2300 to $1700 reduction in prices paid for patients who switched to ASCs. They indicated that their results suggested the use of ASCs had a causal effect on prices paid and had no negative effect on patient health outcomes.

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.

Comparing costs of a senior wellness care redesign in group and independent physician practices of an accountable care organization.
Primary care redesign for older adult patients is currently ongoing in countries with aging populations. One of the main challenges of this type of transformations is how to estimate implementation costs in different types of health care delivery organizations. This study compares start-up and incremental expenses of implementing a primary care redesign across 2 organization types.

A flexible model for the mean and variance functions, with application to medical cost data.
The authors considered an extension to generalized linear models by assuming nonlinear associations of covariates in the mean function and allowing the variance to be an unknown but smooth function of the mean. They discussed their application of the model to the annual medical costs of heart failure patients in the clinical data repository at the University of Virginia Hospital System.
