Integrating Patient Education Into the Glaucoma Clinical Encounter: A Lean Analysis.

PURPOSE

The main purpose of this study was to use Lean analysis to identify how often and when wait times occur during a glaucoma visit to identify opportunities for additional patient engagement.

METHODS

This prospective observational time-motion study measured process and wait times for 77 patient visits from 12 ophthalmologists at an academic glaucoma clinic over a 3-month period. Value stream maps visually diagramed the process of a clinical visit from the patient's perspective. Descriptive statistics were calculated for process times, wait times, and the frequency of 10+ minute wait times during each part of the visit. Key stakeholders participated in a root cause analysis to identify reasons for long wait times. The main outcome measure was average times (hours: minutes: seconds) for process times and wait times.

RESULTS

Twenty-nine new visit (NV) patients and 48 return visit (RV) patients were included. Total time in clinic was 187.1±44.5 (mean±SD) minutes for NV patients and 102.0±44.7 minutes for RV patients. Wait time for NV patients was 63.7±33.4 minutes (33.1% of total appointment time) and for RV patients was 52.6±31.6 minutes (49.4% of the total appointment time). All NV patients and 87.5% of RV patients had at least one 10+ minute wait time during their clinic visit and the majority (75.9% NV, 60.4% RV) had >1.

CONCLUSIONS

Currently, sufficient wait time exists during the visit for key portions of glaucoma education such as teaching eye drop instillation.
