Association of the Patient Protection and Affordable Care Act with ambulatory quality, patient experience, utilization, and cost, 2014-2016.
The national impact of the Patient Protection and Affordable Care Act (ACA) continues to be debated. The purpose of this cross-sectional study was to determine the relationship between the ACA and ambulatory quality, patient experience, utilization, and cost by comparing outcomes before (2011-2013) and after (2014-2016) ACA implementation. The study focused on United States adults between 18 and 64 years of age with income less than and greater than or equal to 400% of the federal poverty level (FPL), who had responded to the annual Medical Expenditure Panel Survey. Researchers conducted analysis of data from a sample of 123,171 individuals between January 2021 and March 2022. The study found that after the implementation of ACA, adults with income levels less than 400% of the FPL received increased high value care such as diagnostic and preventive testing when compared with adults with income 400% or higher of the FPL, and there were no differences in the other quality measures. Individuals with income less than 400% of the FPL had greater improvements in access, experience, and communication measures compared with those who had income greater than or equal to 400% of the FPL. Receipt of primary care services increased for individuals with lower income compared to individuals with higher income and for those with lower income compared to those with higher income, total out-of-pocket expenditures decreased. There were no other differences in utilization or cost between those groups. The researchers concluded that in this study, the ACA was not associated with changes in utilization, quality, or cost, but was related to decreased out-of-pocket expenditures and improved patient access, communication, and experience.

Reference-based benefits for colonoscopy and arthroscopy: large differences in patient payments across procedures but similar behavioral responses.
This study examined how reference-based benefits (RBB) affect out-of-pocket payments across outpatient procedures. The California Public Employees’ Retirement System (CalPERS) applied RBB only to outpatient procedures performed in a hospital outpatient department (HOPD) and not to outpatient procedures performed in a lower cost ambulatory surgery center. Claims from 2009-2013 on arthroscopy and colonoscopy services were analyzed. CalPERS patients paid an average of 63.9% more for HOPDs than ambulatory surgery centers in 2012, but for arthroscopy there was no statistically different cost sharing. This led to high-priced HOPDs being less likely to be chosen by CalPERS patients for both procedures.

Public and private payments for physician office visits.
Using data for 2014-15 from the Medical Expenditure Panel Survey to estimate standardized payments for nonelderly adults' physician office visits by type of insurance, researchers found that adults with public insurance, especially Medicaid, had substantially lower provider payments, out-of-pocket spending, and third-party payments than their peers with employer-sponsored or Marketplace insurance.

Reference-based benefit design changes consumers' choices and employers' payments for ambulatory surgery.
The researchers analyzed the impact of reference-based benefit (RBB) designs on cataract surgery patients choice of less-expensive ambulatory surgery centers over more expensive hospital outpatient departments. Examining two groups of patients, one in plans incorporating RBB and the other in non-RBB plans, they found that the shift to RBB led to an 8.6 percent increase in ambulatory surgery centers as well as a 19.7 percent decrease in payments per procedure.
