Cost analysis and complication rate comparing open, mini-open, and all arthroscopic rotator cuff repair

Abstract

Hypothesis/Background: Value-based healthcare delivery models are becoming increasingly common and are driving cost effectiveness initiatives. Rotator cuff repair (RCR) is a commonly performed procedure with some variations on the specific surgical technique. The purpose of this study was to perform a comprehensive analysis of the cost, complications, and readmission rates of 3 categories of RCR techniques (open [oRCR], combined arthroscopically assisted and mini-open [CRCR], and all arthroscopic [ARCR]) at a high-volume institution. Methods: All RCR procedures performed by 2 fellowship-trained shoulder surgeons at a single institution between 2012 and 2017 were retrospectively identified. These consisted of oRCR, CRCR, and ARCR repair techniques. One surgeon performed oRCR and CRCR, and the second surgeon performed ARCR. A cost analysis was designed to include a period of 60 days preoperatively, the index surgical hospitalization, and 90 days postoperatively, including costs of any readmission or reoperation. Results: The cohort consisted of 95 oRCR, 233 CRCR, and 287 ARCR. Median standardized costs were as follows: preoperative evaluation $486.03; index surgical hospitalization oRCR $9,343.10, CRCR $10,057.20, and ARCR $10,330.60; and postoperative care $875.02. Preoperative and postoperative costs did not vary based on the type of RCR performed. However, significant differences were observed among index surgical costs (P = .0008). The highest standardized cost for hospitalization for both the CRCR group and the ARCR group was related to the cost of the operating room and the implants. The 90-day complication, reoperation, and readmission rates were 1.1%, 1.1%, and 2.1% in the open group; 0.8%, 0.8%, and 1.7% in the combination group; 0%, 0%, and 1.7% in the all arthroscopic group, respectively. There were no significant differences among the 3 surgical procedures with respect to complication (P = .26), reoperation (P = .26), and readmission rates (P = .96). Discussion/Conclusions: In this investigation, the median standardized costs for RCR inclusive of 60-day workup and 90-day postoperative care were $10,704.15, $11,418.25, and $11,691.65 for oRCR, CRCR (average added cost $714.10), and ARCR (added cost $987.50), respectively. The group complication, reoperation, and readmission rate were 0.5%, 0.5%, and 1.8% with no significant differences between the varying techniques, respectively. This retrospective cost analysis and complication profile may serve as a useful reference as surgeons consider engaging in bundled payment for RCR. As value based initiatives continue to progress, implant cost may serve as an actionable area for cost reduction.
