Feasibility Study of Three-Phase Implementation of International Consortium for Health Outcomes Measurement Depression and Anxiety Standard Set in an Outpatient Consultation-Liaison Psychiatry Practice

Objective: We describe a three-phase implementation of the International Consortium for Health Outcomes Measurement Depression and Anxiety Standard Set in a Consultation-Liaison Psychiatry practice. Methods: During the preintervention phase, we reviewed patient-reported outcome tools and engaged stakeholders and leadership. During phase 1, the standard set was converted into an electronic previsit intake assessment that was implemented in a physician champion's practice. Patients completed the intake on a tablet, and computer adaptive testing was used to reduce response burden. Physician-facing data display facilitated use during subsequent in-person visits. An electronic version of the follow-up standard set was used during follow-up visits. During phase 2, a second physician tested scalability and the intervention was disseminated department wide in phase 3. Results: During phase 1, 186 intakes and 67 follow-up electronic patient-reported outcome sets were completed. Average patient age was 54 years, and 44% were male. On average, patients ranked the tool 4.4 out of 5 and spent 22 minutes completing the intake. Time-driven activity-based costing found the new process to be cost-effective. During phase 2, 386 patients completed electronic patient-reported outcome sets, with 315 follow-up visits. Patients ranked the tool as 4.0 out of 5 and spent 26 minutes completing the questions. During phase 3, 2166 patients completed intake electronic patient-reported outcome sets and 1249 follow-up visits. Patients ranked the tool 4.3 out of 5 and spent 26 minutes on it. Scores and completion time did not differ greatly between phases. Conclusions: Integration of the International Consortium for Health Outcomes Measurement Depression and Anxiety Standard Set is feasible. Future research comparing International Consortium for Health Outcomes Measurement set with other approaches and in different settings is needed.
