title: Surgical Services in Critical Access Hospitals, 2011.
abstract: In this policy brief we describe the types and volume of major surgical services provided in the inpatient and outpatient settings of Critical Access Hospitals (CAHs) in 2011. Major surgical services are those procedures that require use of an operating room (OR), regardless of whether the procedure was inpatient or outpatient. Key Findings (1) CAH discharges of patients having a major surgical procedure that required use of an OR were analyzed from four regionally representative states: Colorado, North Carolina, Vermont, and Wisconsin. The average surgical volume among all CAHs in the sample was 624 procedures per CAH per year, and only 6.8 percent of CAHs performed none. (2) The average portion of all surgery volume performed on an outpatient basis in CAHs is 77 percent. Inpatient procedure volume ranged between 20 percent and 24 percent of total surgical volume across the four states. Most of the research literature on surgery in CAHs focus on inpatient procedures only, thus missing a significant portion of the surgery volume that CAHs perform. (3) The high correlation (0.86, p <0.0001) indicates that the 3:1 ratio of outpatient-to-inpatient surgical volume was relatively consistent across CAHs. (4) Operations on the musculoskeletal system, the eye, and the digestive system accounted for 67 percent on average of all surgical procedures in CAHs. Many surgical procedures are performed on an inpatient and outpatient basis, but some are performed exclusively in one setting.
