There is no clear link between how much competition a hospital faces and surgical outcomes, according to a study published Aug. 2 in JAMA Surgery.
Researchers from the Ann Arbor-based University of Michigan analyzed Medicare Provider Analysis and Review files collected between 2015 and 2018. They focused on "beneficiary index admission for a procedure as well as any subsequent hospitalization," and compared the data with information on hospital characteristics culled from the Annual Survey of the American Hospital Association.
Across 10 high-risk procedures — including bariatric surgery, open aortic aneurysm, esophagectomy and hip and knee replacements — there was no consistent difference in monthlong mortality rates when comparing hospitals located in communities with a high level of competition versus a lower level of competition from other hospitals.
Thirty-day readmission trends also showed that competition does not play a measurable factor in surgical outcomes for five of the procedures studies. In fact, three of the surgeries — bariatric surgery, esophagectomy and pancreatectomy — showed no difference in outcomes.
