Medicare Accountable Care Organizations and the adoption of new surgical technology.
Dissemination of new surgical technology is a major contributor to healthcare spending growth. Accountable care organization (ACO) policy aims to control spending while maintaining quality. As a result, ACOs provide incentive for hospitals to selectively adopt newer procedures with high value. In this retrospective cohort study the investigators concluded that despite ACO policy incentives to selectively adopt newer surgical technology, ACO participation was not associated with differences in rate of surgery or use of newer surgical technology for 6 major surgical procedures.

Impact of statewide essential health benefits on utilization of bariatric surgery.
This study looked at the utilization of bariatric surgery after it was included in the Affordable Care Act’s essential health benefits program. The program required individual and small-group insurance plans in 23 states to cover the surgery. Investigators used IBM MarketScan commercial claims data from 2009 to 2016. While bariatric surgery utilization increased in all states after ACA implementation, it was no greater in states with a bariatric surgery essential health benefit. Reasons why can be explored in further studies.

Association of statewide certificate of need regulations with percutaneous coronary intervention appropriateness and outcomes.
This study sought to characterize the association between state certificate of need (CON) regulations and percutaneous coronary interventions (PCI) appropriateness. The investigators found that states with CON had lower proportions of rarely appropriate PCI s, but the absolute differences were small. The investigators note that the findings suggest that CON regulations alone may not limit rarely appropriate PCI among patients with and without acute coronary syndrome.

Effects of the Medicare Modernization Act on spending for outpatient surgery.
The objective of the study was to examine the effects of Medicare's revised ambulatory surgery center (ASC) payment schedule on overall payments for outpatient surgery. The study concluded that despite lessening demand, reduced ASC facility payments did not curb spending for outpatient surgery. In fact, overall payments actually increased following the policy change, driven by higher average episode payments.

Impact of Medicaid expansion on cardiac surgery volume and outcomes.
The objective of this study was to evaluate the effect of Medicaid expansion on cardiac surgery volume and outcomes comparing one state that expanded to one that did not. It concluded that Medicaid expansion was associated with fewer uninsured cardiac surgery patients and improved predicted risk scores and morbidity rates. In addition to improving health care financing, Medicaid expansion may positively affect patient care and outcomes.

Insurance expansion and the utilization of inpatient surgery: evidence for a "Woodwork" effect?
The researchers examined rates of elective surgery in previously insured individuals before and after Massachusetts health care reform. They observed no increase in the overall rate of selected discretionary inpatient surgeries in Massachusetts versus control states for the entire population , as well as among the white and low-income subgroups.

The effect of pre-Affordable Care Act (ACA) Medicaid eligibility expansion in New York State on access to specialty surgical care.
Using the natural experiment of Medicaid expansion in New York (NY) State in October 2001, the study investigators examined whether Medicaid expansion increased access to common musculoskeletal procedures for Medicaid beneficiaries. They concluded that Medicaid expansion in NY State significantly improved access to common musculoskeletal procedures for Medicaid beneficiaries.
