Obesity linked with increased operative time during THA
Recently published results showed obesity as the major driver of increased operative time in patients undergoing total hip arthroplasty, with congestive heart failure contributing to the greatest increase in overall room time during the procedure.
Using the American College of Surgeons National Surgical Quality Improvement Program database, researchers identified 30,361 patients who underwent total hip arthroplasty (THA) between 2006 and 2012. Researchers used patient demographics, comorbidities (including BMI) and anesthesia type to create generalized linear models to identify independent predictors of increased operative time and room time.
Results showed morbid obesity had an increased operative time of 13 minutes and was the greatest predictor of increased operative time. Researchers found operative time increased incrementally with BMI class. Use of general anesthesia also increased operative time by 11 minutes, according to results. Researchers noted male gender, white race, smoking and age were linked with a significant change in operative time.
Similar to an increase in operative time, results showed room time had a substantial increase among patients who were morbidly obese, with the use of general anesthesia, white race, male gender and age. However, congestive heart failure was linked with the greatest increase in overall room time, showing an increase of 20 minutes, according to researchers. – by Casey Tingle
