Excessive Preoperative Testing in Otolaryngology: A Retrospective Comparison of Primary Care and Perioperative Providers.

Abstract

To assess the association between provider type (primary care provider [PCP] or perioperative provider) and excessive preoperative testing. Cross-sectional study. Academic medical center. Electronic medical records of adult patients who obtained an outpatient preoperative assessment and underwent surgery in the Department of Otolaryngology-Head and Neck Surgery during the first 2 weeks of January 2019 (n = 94) were reviewed. Patients receiving preoperative tests beyond those recommended by the guidelines were deemed to have had excessive testing. Descriptive statistics were used to characterize the study population. Simple and multivariate logistic regression were used to analyze the association between the outcome and the predictor variables. Overall, 44.7% of preoperative evaluations had excessive testing. Patients who had their preoperative evaluation performed by a perioperative provider had 89% lower odds of having excessive preoperative testing compared to those evaluated by a PCP (odds ratio = 0.11, 95% confidence interval: [0.03, 0.37], P < .001). Female sex, younger age, and higher risk of major adverse cardiac events were associated with greater odds of excessive testing. Excessive preoperative testing is more commonly performed by PCPs compared to perioperative providers. These results give preliminary evidence in support of a potential shift in the clinical responsibility of preoperative evaluation from PCPs to perioperative providers in order to reduce excessive testing and promote high-value health care. The next steps include validating these findings, identifying reasons for differential guideline concordance, and intervening accordingly.
