Evaluation of a nurse-led glaucoma assessment clinic for non-complex patients.

Abstract

The purpose of this study was to assess the safety, feasibility and effectiveness of a nurse-led glaucoma assessment clinic service. Glaucoma is a group of serious, irreversible optic neuropathies that progressively damage the optic nerve resulting in blindness. Over 64.3 million people globally are affected by glaucoma with numbers projected to increase to 111.8 million by 2040. Glaucoma is a major public health concern that requires the development of innovative models of care to meet current and future health care demands. A mixed method design was used to evaluate the assessment of non-complex glaucoma patients attending a new nurse-led clinic. Under an ophthalmologist's supervision, the glaucoma nurse completed 100 hof clinical training and assessment to ensure they were competent in completing and interpreting the required glaucoma assessment protocols. Interrater reliability between the glaucoma nurse and ophthalmology doctor was undertaken. Glaucoma patient waitlist appointment data were also compared before and after the introduction of the nurse-led clinics. This study adhered to the SQUIRE checklist for the reporting of excellence with quality improvement projects. Patients contributed to the evaluation of this new nurse-led service by providing follow-up feedback on their experience. Agreement between clinicians for appropriate follow-up appointment times was high with 93% (n= 315) agreement achieved. Furthermore in 297 (87.5%) cases, both clinicians agreed on the patient being referred to the doctor for follow-up review. Glaucoma consultations were shown to increase from 3,115 appointments in 2019/20 to 3,504 appointments in 2020/21 after the introduction of the nurse-led clinic. The nurse-led clinics accounted for 14.5% (n= 512) of clinic appointments. The introduction of the nurse-led glaucoma assessment clinic service allowed patients to be reviewed safely, efficiently and satisfactorily. This new service subsequently allowed for more complex glaucoma patients to be seen bythe ophthalmologists. Findings revealed that suitably trained glaucoma nurses are able to clinically assess and safely monitor stable non-complex glaucoma patients. Highlights the need for appropriate investment in clinical training and supervision to ensure that glaucoma assessment nurses are adequately prepared to undertake this new practice role.
