Does body mass index influence intraoperative costs and operative times for open transforaminal lumbar interbody fusion? A time-driven activity-based costing analysis.

ABSTRACT:

Background

The increasing prevalence of obesity has raised concerns about its impact on surgical outcomes and healthcare costs. This study evaluates the influence of Body Mass Index (BMI) on intraoperative costs and operative times during open Transforaminal Lumbar Interbody Fusion (TLIF) procedures using a Time-Driven Activity-Based Costing (TDABC) approach.

Methods

A retrospective analysis was conducted on 279 patients who underwent TLIF between 2019 and 2022. Patients were categorized into 5 BMI cohorts: healthy weight (BMI 18.5-24.99), overweight (BMI 25.0-29.99), Class I obese (BMI 30.0-34.99), Class II obese (BMI 35.0-39.99), and Class III obese (BMI >40). Intraoperative costs were calculated using TDABC methodology, with costs segmented into supply and personnel expen
