Study Targets Impact Of Health Insurance Expansion on Surgery

Tue, 07/08/2014 - 12:53pm

The full implementation of the Affordable Care Act's (ACA) national health insurance expansion could result in many more discretionary surgical procedures in the next few years, based on how utilization changed after an earlier insurance reform in Massachusetts.

Authored by Chandy Ellimoottil, M.D., of the University of Michigan, Ann Arbor, and colleagues, the report analyzes the Massachusetts insurance expansion and utilization of discretionary and non-discretionary surgical procedures. The authors used state inpatient databases from Massachusetts and two control states (New Jersey and New York) to identify adults who underwent discretionary procedures (e.g. elective procedures such as joint replacement and back surgery) and nondiscretionary procedures (e.g. cancer surgery and hip fracture repair) from 2003 through 2010. The transition point for insurance reform was July 2007.

They found that a total of 836,311 surgical procedures were identified during the study period. Insurance expansion was associated with a 9.3 percent increase in discretionary surgery in Massachusetts and a 4.5 percent decrease in non-discretionary surgery. Authors estimate the ACA could yield an additional 465,934 discretionary surgical procedures by 2017.

The authors state: "Our collective findings suggest that insurance expansion leads to greater utilization of discretionary inpatient procedures that are often performed to improve quality of life rather than to address immediately life-threatening conditions. Moving forward, research in this area should focus on whether greater utilization of such procedures represents a response to unmet need or changes in treatment thresholds driven by patients, providers or some combination of the two."
