IntroductionPreoperative medical optimization is necessary for safe and efficient care of the orthopaedic trauma patient. To improve care quality and value, a preoperative matrix was created to more appropriately utilize subspecialty consultation and avoid unnecessary consults, testing, and operating room delays. Our study compares surgical variables before and after implementation of the matrix to assess its utility.MethodsA retrospective review of all orthopaedic trauma cases 6 months before and after the use of the matrix (2/2021-8/2021) was conducted an urban, level one trauma centre in collaboration with internal medicine, cardiology, anaesthesia, and orthopaedics. Patients were separated into two cohorts based on use of the matrix during the initial orthopaedic consultation. Logistic regressions were performed to limit significant differences in comorbidities. Independent samples t-tests and Chi-squared tests were used to compare means and proportions, respectively, between the two cohorts.ResultsIn total, 576 patients were included in this study (281 pre- and 295 post-matrix implementation). Use of the matrix resulted in no significant difference in time to OR, LOS, readmissions, or ER visits; however, it resulted in 18% fewer overall preoperative consults for general trauma, and 25% fewer pre-operative consults for hip fractures. Older patients were more likely to require a consult regardless of matrix use. When controlling for comorbidities, patients with renal disease were at higher risk for increased LOS.ConclusionUse of an orthopaedic surgical matrix to predict preoperative subspecialty consultation is easy to implement and allows for better care utilization without a corresponding increase in complications and readmissions. Follow-up studies are needed to reassess the relationships between matrix use and a potential decrease in ER to OR time, and validate its use.© 2023.
