Abstract
PURPOSE Hydroxychloroquine (HCQ) is an important medication for patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and other rheumatic diseases. Although it is well-tolerated and cost-effective, the risk of HCQ retinal toxicity is of increasing concern. The aim of this study is to re-examine the HCQ retinal toxicity incidence rate, risk factors and clinical course after discontinuation. METHODS We designed a prospective population-based cohort study in adult patients with SLE or RA, currently receiving HCQ for five or more years, who are residents of British Columbia (BC), Canada. Based on administrative data, we identified 5508 eligible participants (1346 SLE and 4162 RA). They will participate in annual or biannual retinal screening over 5 years in alignment with the recently revised American Academy of Ophthalmology guidelines. To standardise procedures for retinal screening, imaging, diagnostic criteria, severity staging and data transfer, a consensus meeting was convened in December 2019 with participation of BC retinal specialists and the research team. Agreement was attained on: use of spectral domain-optical coherence tomography as the primary objective screening modality; classification of images into categories of normal, equivocal or abnormal; and transferring the equivocal and abnormal images plus corresponding subjective test results via cloud-based server from each clinic to a reading centre. Confirmation of HCQ retinal toxicity diagnoses and severity staging will be performed by three independent and masked reviewers. The incidence of HCQ retinal toxicity will be calculated, accounting for the competing risk of death. Hazard ratios for each risk factor will be calculated for the risk of HCQ retinopathy, after adjusting for confounders. We will also estimate the risk of HCQ retinal toxicity progression over 5 years. ETHICS AND DISSEMINATION This study has received approval from the University of British Columbia Clinical Research Ethics Board (H20-00736) and the Vancouver Coastal Health Research Institute.

Abstract
OBJECTIVE Hydroxychloroquine (HCQ) is commonly used in the treatment of various autoimmune diseases related to its many benefits and favorable safety profile. Although HCQ retinopathy was considered to be uncommon, a prevalence of 7.5% was described in a recent study making early detection critical. The most updated screening guidelines by the American Academy of Ophthalmology were published in 2016; however, it lacked pediatric-specific recommendations and the overall compliance with screening guidelines was poor in previous studies. We developed a quality improvement (QI) initiative aiming to create institutional screening recommendations. Additionally, to increase eye screening in pediatric rheumatology clinic for patients receiving HCQ from 65% to 85% in 12 months and to sustain that rate for at least 6 months. METHODS We formed a multidisciplinary team of pediatric rheumatologists and ophthalmologists, clinical pharmacist, clinic nurses, QI specialist, quality data technician and administrative staff. We included patients receiving HCQ and who were evaluated at Nationwide Children's Hospital rheumatology clinic. A key driver diagram was formulated to identify barriers to compliance and determine possible interventions. Main interventions included summarizing screening guidelines in a step by step algorithm, increasing awareness of these guidelines among patients and providers, improving collaboration and communication with ophthalmologists, and initiating pre-visit planning. RESULTS Baseline performance data included 164 patients. Fifty-four (33%) of those patients were at high risk for HCQ retinopathy. Of them, 50% were on HCQ dose of >5 mg/kg/day and 31.5% had been taking HCQ for ≥5 years. Two center line shifts were noticed over the course of the project. The target of 85% compliance was reached in February 2019 and was sustained until December 2019. CONCLUSIONS Our study highlights the importance of interdisciplinary communication to increase awareness of screening guidelines among medical providers and patients. Pre-visit planning played a major role in identifying patients and opportunities for optimizing eye screening in patients at risk for HCQ retinopathy. Collaboration between rheumatologists and ophthalmologists is crucial in managing patients on HCQ. The implementation of same-day eye screening allowed this collaboration to be more efficient. Future efforts are being directed at monitoring and improving utilization of the effective interventions.
