Nurse triage, diagnosis and treatment of eye casualty patients: a study of quality and utility.

INTRODUCTION: Patients presenting to the Accident and Emergency department of a district general hospital with an eye problem are referred directly to a dedicated eye casualty service. They are then triaged by a staff nurse from the eye department. This eye casualty sees around 8000 patients per annum. This study assesses whether the nurse triage of eye casualty patients forms an effective filter of problems which do not require the attention of the doctor on duty. The incidence of cases of misdiagnosis and inappropriate discharge of patients resulting in a delay in diagnosis and treatment was also assessed. METHODS: All patients presenting in a 3-month period managed solely by the triage nurse, were identified from the casualty register, and the hospital records retrieved and examined. RESULTS: Four hundred and forty of a total 1976 patients (22%) were seen exclusively by triage nurses; eight (2.5%) of these 440 patients returned unplanned to the eye department. In all cases it was considered that the return of the patient would not have been preventable by initial attention of the ophthalmologist on duty. DISCUSSION: With appropriate threshold for referral, nurses trained in slit lamp examination can offer a successful service to safely diagnose and treat common eye casualty presentations.
