Abstract

BACKGROUND: Contemporary surgical approaches to pituitary pathologies include transsphenoidal microsurgical and, more recently, endoscopic techniques. Data reporting direct costs in transsphenoidal pituitary surgery are limited. OBJECTIVE: To examine direct costs (including overall total, hospital/facility, and physician payments) of microscopic and endoscopic pituitary surgery and evaluate predictors of differential costs in transsphenoidal pituitary surgery using a national database. METHODS: The Truven MarketScan® database 2010-2014 (IBM, Armonk, New York) was queried and patients undergoing microscopic and/or endoscopic transsphenoidal pituitary surgery identified. Mean costs and predictors of differential costs were analyzed using analysis of variance and generalized linear models. Beta-coefficients (β) assessed relative contributions of independent predictors. RESULTS: Mean overall total ($34 943.13 [SD ± 19 074.54]) and hospital/facility ($26 505.93 [SD ± 16 819.52]) payments were higher in endoscopic compared to microscopic surgeries (both P <. 001). Lengths of hospital stay (LOS) were similar between groups. Predictors of overall total and hospital/facility payments were similar including surgical technique, age, geographical region, comorbidity index, postoperative surgical and medical complications, and LOS with LOS being the most significant predictor (β = 0.27 and β = 0.29, respectively). Mean physician payments ($4549.24 [SD ± 3956.27]) were similar in microscopic and endoscopic cohorts (P =. 26). Predictors of physician payments included age, health plan, geographical region, postoperative surgical complications, and LOS with health plan being the most significant predictor (β =-0.21). CONCLUSION: Higher overall total and hospital/facility costs are associated with endoscopic transsphenoidal pituitary surgery compared to microsurgery. In contrast, physician reimbursements are similar between techniques. Whereas LOS was the strongest predictor of overall total and hospital/facility costs, health plan was the strongest predictor of differential physician reimbursements.
