We agree that the safety of commissioned services is of importance, and we believe that novel services should be commissioned with inbuilt service evaluation, but we acknowledge the inherent barriers to doing this. We were grateful that the companies involved in our study were keen to have independent evaluation that enabled system learning and improvement of services. As Harper et al. note, clinical record abstraction has some downsides. This has further disadvantages for an acute eye service appointment for symptomatic individuals. For example, a practitioner could record no tear/detachment for a patient presenting with flashing lights and/ or floaters which, according to the records, the practitioner may appropriately decide not to refer the patient onwards for treatment. This does not tell us, however, whether the patient had a retinal tear or detachment that was simply not detected. It is likely that a practitioner's clinical record would justify their choice of action. Direct patient contact, therefore, may be an appropriate method of determining major errors in an acute eye care service. We therefore welcome Harper et al. bringing a discussion of the challenges in appropriately documenting the safety of primary eye care services. In addition to the lack of falsenegative data being an issue when determining the safety of a service, this also poses questions for the system's costeffectiveness. Despite work attempting to elucidate the costeffectiveness of optometryled acute eye care services, 5 without knowing the precise details of the erroneous management (e.g., falsenegatives), true costeffectiveness cannot be ascertained. For example, mismanagement of patients with early symptoms of stroke has the potential to incur a significantly larger cost to the health care system and society, relative to a falsepositive hospital referral. The lack of specifics in the methodology of Williams et al. makes comparison to other studies difficult. However, the results of a teleophthalmology service delivered at Moorfields Eye Hospital are interesting and in line with our study, when examining representation rates. Specifically, 35.5% of patients who had a teleconsultation by an ophthalmologist represented, unplanned, to the emergency eye service within one month of their initial consultation. For patients in our study, 26.8% reattended (11.1% to the phone line and 15.7% elsewhere) after teleconsultation. In both studies, rates of representation were lower after a facetoface appointment. Specifically, 19.8% fewer patients represented after a facetoface ophthalmology appointment (15.7% represent rate) and 26% fewer patients represented after a facetoface optometry appointment (0.7% represent rate). Whilst the teleophthalmology service differed markedly from that of the service in our study, one distinction is that in the service examined by Li et al., patients were able to choose whether they were seen","PeriodicalId":520731,"journal":{"name":"Ophthalmic & physiological optics : the journal of the British College of Ophthalmic Opticians (Optometrists)","volume":" ","pages":"660-661"},"PeriodicalIF":2.9,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39960763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their research raises important questions about how clinical safety in such services, and indeed primary eyecare services in general, should be determined. Evaluations of effectiveness of UK primary eyecare services have typically focussed on false positives, for example, false positive referrals to the Hospital Eye Service (HES), with false negatives rarely being considered. Indeed, there are interesting methodological challenges in examining for false negatives, but also, we suggest, some novel opportunities with the advent of greater digital interconnectedness in eyecare pathways. In terms of challenges, one difficulty is defining what constitutes a false negative, with different methodologies and their consequent different criterion options for what comprises a false negative potentially being a major source of difference when investigating similar services. In the absence of an established definition of what constitutes a COVID19 Urgent Eyecare Service (CUES) optometrist's incorrect diagnosis or an unsuccessful recommendation, Swystun and Davey were obliged to set their own definitions. They used direct patient contact via telephone following access to CUES, quantifying cases of missed pathology and/or failure to appropriately manage patients’ symptoms in a sample of over a thousand episodes. Their “incorrect” diagnoses were determined by patients’ accounts, but they also went on to define “major errors”, a definition which included errors or omissions judged to have the potential to cause harm. Although the precise definitions of CUES misdiagnoses and unsuccessful recommendations might be open for debate, consensus is more likely to be found regarding a potential for harm category. While the authors describe some limitations of reliance on patient reported outcomes, their point that the purpose of acute eyecare relates to resolving patients’ symptoms highlights the advantage such a direct approach can have in the context of urgent eyecare. Examining clinical records is another approach sometimes employed to establish safety. Interestingly, Sheen et al.’s study examining clinical safety in an urgent eyecare scheme used a combination of clinical record review and telephone interview outcomes to establish inappropriate management, reporting a substantially lower false negative rate than Swystun and Davey, albeit in a different service (not reliant on the substantive telemedicine element within CUES during the pandemic). Konstantakopolou et al. also employed record review to examine clinical safety in a minor eye conditions scheme (MECS), examining not only referred but also nonreferred patients’ records to assess for appropriate management; however, while this approach can be used to capture clinical management against guidelines, it is reliant on the veracity of recorded details, with potential","PeriodicalId":520731,"journal":{"name":"Ophthalmic & physiological optics : the journal of the British College of Ophthalmic Opticians (Optometrists)","volume":" ","pages":"658-659"},"PeriodicalIF":2.9,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39960765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
