Trial Outcomes & Findings for Reducing VA No-Shows: Evaluation of Predictive Overbooking Applied to Colonoscopy (NCT NCT01639443)
NCT ID: NCT01639443
Last Updated: 2018-04-12
Results Overview
Investigators' primary objective will be to evaluate the impact of no-show predictive overbooking on percentage of the GI endoscopy clinic that are filled on a given day. Days where at least one Fast-tracked patient attended an appointment were compared to days where only Control patients attended appointments. Percentage of GI Clinic Capacity is calculated as the number of appointments completed divided by number of appointment spots available on a given day. This percentage was compared between Fast-tracked days and Control days, using data from 1672 patients.

Fast-tracked
Patients who volunteer to enroll in "fast-track" line, which gives them an opportunity to overbook their appointment for endoscopy earlier in a predictive no-show slots.
Predictive no-show overbooking: During intervention period, every Veteran scheduled for an upper endoscopy will be offered "fast-track" offer, which gives them a chance to get their endoscopy procedure done earlier than usual scheduling by overbooking their appointment in a predictive no-show slot.

PRIMARY outcome
Timeframe: After 12 months of running study in clinicPopulation: These 1672 patients are a subset of all patients who were enrolled in this study. We dropped data on a first wave of participants (69 Fast-tracked and 3294 Controls) because of problems incorporating recruitment strategy into clinic. However, data from these individuals was used to build predictive model.
Investigators' primary objective will be to evaluate the impact of no-show predictive overbooking on percentage of the GI endoscopy clinic that are filled on a given day. Days where at least one Fast-tracked patient attended an appointment were compared to days where only Control patients attended appointments. Percentage of GI Clinic Capacity is calculated as the number of appointments completed divided by number of appointment spots available on a given day. This percentage was compared between Fast-tracked days and Control days, using data from 1672 patients.
