Purpose: To study the proportion of patients treated with hydroxychloroquine in Health Area VII of Murcia following the screening recommended by the international guidelines and to implement a system to improve the screening efficacy.
Methods: We studied the patients in Health Area VII of Murcia, Spain, treated with hydroxychloroquine between January and November 2019 to find out whether patients were correctly screened for retinopathy. Demographic data, medical specialty prescribing hydroxychloroquine, disease, year of onset and examinations performed in our Ophthalmology Service were collected.
Results: A total of 202 medical records were reviewed. Baseline ophthalmologic exams were performed in 63.9% of cases: fundus examination (96.9%) and optical coherence tomography (OCT) (33.3%). Follow‐up examination was performed in 61.8% of cases. Follow‐up was complete, with OCT, 10‐2 visual field and autofluorescence image in only 2.4% of patients. The time between revisions was 1.6 years on average. These results strongly deviated from the guidelines. We planned a strategy to improve the screening of these patients. We developed a computer database that allows the voluntary and automatic registration of patients treated with hydroxychloroquine, including contact and demographic data, start date of treatment, the daily dose and retinopathy risk factors. With this database, the patient's appointment in ophthalmology will be provided with the corresponding tests. The examination will be assessed by telemedicine and the time of the next check‐up will be determined according to the results.
Conclusions: This plan aims to capture most patients starting the treatment with hydroxychloroquine and to carry out the appropriate tests at each visit with strict follow‐up, thus reducing the care load.
