Goal: To determine rapidly acting agents' impact on practice efficiency and cost for outpatient colonoscopy in a screening population.
Background: Propofol-mediated endoscopic sedation is popular due to rapid sedation onset and superior recovery profile compared with sedation with an opioid and benzodiazepine. There are few data on the impact of this type of sedation on the economics and efficiency of an endoscopy unit.
Study: A provider-perspective economic model assessed the ability of propofol and fospropofol disodium (Aquavan, GPI 15715, MGI Pharma) to increase practice efficiency and determined break-even costs based on current colonoscopy reimbursement levels. Reimbursement inputs by practice setting, costs, and recovery profiles-taken from published literature examining time to discharge-were used to populate the model. To measure robustness of model results to changes in base case inputs, sensitivity analyses were performed. Using a Monte Carlo simulation, inputs were varied simultaneously and randomly for 1000 iterations to determine 95% confidence intervals (CI) for break-even costs.
Results: In the time to complete 1 colonoscopy with midazolam/meperidine, 1.76 colonoscopies can be completed with propofol and 1.91 colonoscopies can be completed with fospropofol disodium. This efficiency benefit produced a break-even cost for rapid recovery agents of $71.53 (95% CI: $38.39, $105.67) in a hospital outpatient clinic and $61.48 (95% CI: $41.33, $108.99) in an ambulatory surgical center. One-way sensitivity analyses indicated the break-even cost of these agents was most sensitive to operating costs and time to discharge ratio.
Conclusions: Rapid recovery agents for colonoscopy can improve practice efficiency and offer economic advantages over traditional sedation.
