An evaluation of the safety and effectiveness of telephone triage as a method of patient prioritization in an ophthalmic accident and emergency service

Service changes in the accident and emergency service at Manchester Royal E ye Hospital in England resulted in a telephone triage-based referral servic e for health care professionals. It became clear that this service needed e valuation in order to assure both providers and users of the service that t his referral strategy, based on experienced nurse practitioners making deci sions about patient priority, was safe and effective. The evaluation was ex tended to encompass the other area of the service where telephone referrals tend to be directly from patients. A mixed method was used. Information ga ined within the telephone triage conversation was compared with a final dia gnosis through retrospective analysis of secondary data; the documentation of those patients who were not given access to the service initially was fo llowed-up to ensure that this decision was safe and a number of nurses were questioned about telephone information gathering, using partially structur ed interviews. The study showed that nurse practitioners within the acciden t and emergency service were able to elicit accurate information from the t elephone triage conversation on which to base a decision about patient acce ss in most cases (76% over the whole service). This resulted in the appropr iate prioritization of patients. No patient who needed urgent access to the service was denied it. The decisions made to deny urgent appointments to a number of patients were safe in all cases. It appears that one of the prob lem areas in the gathering of information for prioritization purposes is in the nurses' telephone triage discussions with some, but by no means all, d octors. Some general practitioners seemed unwilling to discuss the patient and give accurate information to a nurse and this is an area which appears to need some further work.
