Reassurance on false negatives in the Manchester COVID19 Urgent Eyecare Service (CUES)

A review of UK primary care pathways for acute ophthalmic conditions

Care pathways for the management of acute ophthalmic conditions have developed and transformed significantly over recent years, owing to a combination of legislative changes, policy implementation and the pressing requirement to redistribute increased demand away from traditional secondary care providers through collaboration with primary care. Following UK healthcare devolution in 1999, each nation has developed and implemented their own strategies for managing the growing demands on acute ophthalmology services. Local commissioning across England has seen Enhanced Service Pathways develop to provide acute eye care by primary care optometrists, with provision and access dependent upon locality. Northern Ireland has seen the implementation of a nationwide Primary Eyecare Acute Referral Service, whilst in Scotland and Wales, the respective Governments have redesigned primary care optometry General Ophthalmic Service contracts to incorporate provision of extended investigations and management of acute conditions by optometrists across the nation, recognising the added benefit of optometrists with higher qualifications. This narrative review summarises both peer reviewed and appropriate grey literature articles reporting on acute eye care pathways in primary care. Despite significant progress, particularly during the global COVID-19 pandemic, there is arguably still a great deal of further research and evaluation required relating to pathway innovation, the role of professionals with higher qualifications, including independent prescribing, the role of telemedicine, reassurance around clinical safety, and how digital interconnectivity could potentially add value to collaborative schemes to meet the growing demand on acute eyecare.

The effectiveness of interventions for optometric referrals into the hospital eye service: A review

PURPOSE

Ophthalmic services are currently under considerable stress; in the UK, ophthalmology departments have the highest number of outpatient appointments of any department within the National Health Service. Recognising the need for intervention, several approaches have been trialled to tackle the high numbers of false-positive referrals initiated in primary care and seen face to face within the hospital eye service (HES). In this mixed-methods narrative synthesis, we explored interventions based on their clinical impact, cost and acceptability to determine whether they are clinically effective, safe and sustainable. A systematic literature search of PubMed, MEDLINE and CINAHL, guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), was used to identify appropriate studies published between December 2001 and December 2022.

RECENT FINDINGS

A total of 55 studies were reviewed. Four main interventions were assessed, where two studies covered more than one type: training and guidelines (n = 8), referral filtering schemes (n = 32), asynchronous teleophthalmology (n = 13) and synchronous teleophthalmology (n = 5). All four approaches demonstrated effectiveness for reducing false-positive referrals to the HES. There was sufficient evidence for stakeholder acceptance and cost-effectiveness of referral filtering schemes; however, cost comparisons involved assumptions. Referral filtering and asynchronous teleophthalmology reported moderate levels of false-negative cases (2%-20%), defined as discharged patients requiring HES monitoring.

SUMMARY

The effectiveness of interventions varied depending on which outcome and stakeholder was considered. More studies are required to explore stakeholder opinions around all interventions. In order to maximise clinical safety, it may be appropriate to combine more than one approach, such as referral filtering schemes with virtual review of discharged patients to assess the rate of false-negative cases. The implementation of a successful intervention is more complex than a 'one-size-fits-all' approach and there is potential space for newer types of interventions, such as artificial intelligence clinical support systems within the referral pathway.
