BACKGROUND: Obesity is increasingly common in @entity1 having total hip arthroplasty, and previous studies have shown a correlation with increased operative time in total hip arthroplasty. Decreasing operative time and room time is essential to meeting the increased demand for total hip arthroplasty, and factors that influence these metrics should be quantified to allow for targeted reduction in time and adjusted reimbursement models. This is the first study to use a multivariate approach to identify which factors increase operative time and room time in total hip arthroplasty. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify a cohort of 30,361 @entity1 having total hip arthroplasty between 2006 and 2012. @entity1 demographics, comorbidities including body mass index, and anesthesia type were used to create generalized linear models identifying independent predictors of increased operative time and room time. RESULTS: Morbid @entity28 (body mass index >40) independently increased operative time by 13 minutes and room time 18 by minutes. @entity712 led to the greatest increase in overall room time, resulting in a 20-minute increase. Anesthesia method further influenced room time, with general anesthesia resulting in an increased room time of 18 minutes compared with spinal or regional anesthesia. CONCLUSION: Obesity is the major driver of increased operative time in total hip arthroplasty. @entity712 , general anesthesia, and morbid @entity28 each lead to substantial increases in overall room time, with @entity712 leading to the greatest increase in overall room time.
