Three-year outcomes of an optometrist-led virtual clinic for new glaucoma referrals.

INTRODUCTION

The purpose of this study was to describe and evaluate the outcomes of an optometrist-led virtual glaucoma clinic (VGC).

METHODS

New patients referred to the glaucoma service who were consultant triaged as 'low risk' were assessed virtually by specialist-trained optometrists in the VGC and either discharged or monitored for a period of 3 years. Ten percent of virtual case notes were audited by a glaucoma consultant to verify quality and generate learning objectives. Retrospective case-note review and analysis of all patients seen in the virtual clinic between 2014 and 2016 was undertaken to determine 3-year outcomes.

RESULTS

A total of 1710 new patients were seen in the clinic between 1 January 2014 and 31 December 2016. Of these, 1033 (60.4%) patients required no outpatient input in 3 years of follow-up. Additionally, 320 (18.7%) were discharged at the first visit, and the proportion of glaucoma suspect and ocular hypertension patients who converted to glaucoma was 12.1% and 5.8%, respectively. At 3 years, 95 patients had died, 159 were lost to follow-up, 576 were discharged and 371 were diagnosed with glaucoma at baseline or during the 3-year follow-up. The cumulative discharge proportion from the service at the end of 3 years was 82.6%. No patients required emergency eye treatment or sight-impairment registration, and of the 12 referred back to the clinic on discharge, only five required ongoing monitoring.

CONCLUSION

This optometrist-led VGC combined two aspects of novel service delivery to reduce the burden of glaucoma monitoring in outpatient departments and consolidate consultant contact to patients requiring more intervention. This model will be of value in units establishing virtual services and looking to expand the role of allied health professionals.
