Quality of refractive error care (Q.REC) in Cambodia, Malaysia and Pakistan: protocol for a cross-sectional unannounced standardised patient study.

Introduction: There are 161 million people living with vision impairment, due to uncorrected refractive errors. A further 510 million people are living with near-vision impairment. There is a need for clearly defined indicators that capture the quality of refractive error service outputs and outcomes and provide insights to shape, change and stimulate action. This study aims to evaluate the quality of refractive error care (Q.REC) in Cambodia, Malaysia and Pakistan, by using unannounced standardised patients (USPs) to identify the proportion of prescribed and dispensed spectacles appropriate for people's refractive error needs and pinpoint/detail opportunities for quality improvement.
Method and Analysis: A cross-sectional Q.REC study will be conducted in randomly selected optical services in Cambodia (180 services, 900 USP visits), the Klang Valley in Malaysia (66 services, 198 USP visits) and in Jhang, Sahiwal and Khanewal districts of Punjab region/state in Pakistan (64 services, 256 USP visits). USPs will receive baseline refractions by three skilled study optometrists/refractionists trained in the Q.REC protocol. USPs will then visit individual optical services, undergo a refraction, purchase spectacles or lenses (if recommended) and record observations about which elements of a refraction and dispensing were conducted. The study optometrist/refractionist will assess each pair of dispensed spectacles by examining the USP's aided visual acuity and visual comfort at distance and/or near and compare the lens prescription to the averaged baseline refraction.
Ethics and Dissemination: This study has been approved by the University of New South Wales Human Research Ethics Committee (HC210102), the National Ethics Committee for Health Research in Cambodia (043 NECHR), National Medical Research Registry and the Medical Research and Ethics Committee (NMRR-21-689-59279) in Malaysia and the College of Ophthalmology & Allied Vision Sciences Ethical Review Board (COAVS 545/2021) in Pakistan. Written informed consent will be obtained from USPs. Service owners will have the opportunity to opt-out verbally or in writing. Results will be disseminated locally through workshops including the relevant local ministry of health personnel and stakeholders, published in peer-reviewed publications and presented at national and international conferences.
