Metacarpal Fracture Fixation in a Minor Surgery Setting Versus Main Operating Room: A Cost-minimization Analysis.

Abstract

Background:The objective of this study was to compare the costs of performing metacarpal fracture fixation in minor surgery (MS) versus the main operating room (OR) at a tertiary care center in Calgary, Alberta, from the institutional perspective.Methods:Data were extracted from the Operating Room Information System and the Business Advisory System by a financial analyst. All data were based on actual expenses from the 2016–2017 fiscal year (US$). Direct costs included: staffing, supply, day (outpatient) surgery unit, post-anesthesia care unit (PACU), and anesthesia (anesthesiologist and equipment) costs. Surgeon and hardware costs were deemed neutral and excluded from the analysis.Results:The total cost of metacarpal fixation in MS was $250, compared to $2,226 in the OR, after surgeon and hardware costs were excluded. Staffing costs are a major contributing factor to cost by location ($75 in MS versus $233 in OR), largely attributable to 0.5 nursing staff per room in MS compared to 3 nursing staff per room in the OR. Supply costs (minor tray, $94 versus case cart, $247) are also greater for OR cases. The combined costs for DSU ($465), PACU ($435), and anesthesia ($247) totaled $1,147 and are only incurred for OR cases.Conclusions:Repair of metacarpal fractures in MS represents a substantial cost-minimization strategy from the institutional perspective. Staffing and supply costs by location and the additional combined costs of DS, PACU, and anesthesia are all contributing factors.
