Cost Drivers Associated With Anterior Shoulder Stabilization Surgery

Abstract

Background: Arthroscopic Bankart repair, open Bankart repair, and the Latarjet procedure are common treatments for anterior shoulder instability; however, little is known of costs by patient- and surgeon-specific factors. This study aimed to identify areas where cost reduction may be achieved. Hypothesis: Increased total charges will be associated with low-volume surgeons and surgical facilities, hospital-owned facilities, open surgical techniques, and patients with at least 1 comorbidity. Study Design: Economic and decision analysis; Level of evidence, 3. Methods: The 2014 State Ambulatory Surgery and Services Databases from 6 states were utilized. There were 3 Current Procedural Terminology codes (23455, 23462, 29806) used to identify open Bankart repair, the Latarjet procedure, and arthroscopic Bankart repair, respectively. Patient demographic and surgical variables were evaluated on a univariate basis, and all significant factors were then included in the multiple linear regression to determine which factors had the largest effect on cost. Total charges billed for the encounter were used as a proxy for cost of surgery. Results: For open Bankart repair, arthroscopic Bankart repair, and the Latarjet procedure, longer operative times increased costs, and high-volume surgical facilities had decreased charges. For the arthroscopic Bankart group, additional factors that increased charges included postoperative hospital admission (US$11,516; P
