Indicators for effective glaucoma care coverage in adults: protocol for a scoping review.

INTRODUCTION: Glaucoma is the leading cause of irreversible blindness worldwide and the number of people with glaucoma is expected to increase to more than 112 million by the year 2040, making it a disease of public health interest. However, there is no consensus on public health indicators to monitor glaucoma care coverage. This scoping review aims to summarise published indicators for monitoring effective glaucoma care coverage globally, focusing on care needs, use of care services and outcomes achieved. METHODS AND ANALYSIS: We will include studies that report the development and use of public health indicators for effective glaucoma care coverage in patients aged 18 years and older. Studies published from 1 January 2000, in all languages, will be included, provided they can be accurately and easily translated into English using Google Translate. Searches will be conducted by an information specialist on MEDLINE, Embase, Global Health and CENTRAL in the Cochrane Library. Two reviewers working independently will screen the search results, select studies for inclusion and extract data; any disagreements will be discussed with or resolved by a third reviewer. Data will be presented in tabular form, followed by a narrative synthesis based on the review objectives. ETHICS AND DISSEMINATION: Ethical approval is not required as the review will use published data. Results will be published in a peer-reviewed journal, and summarised results will be available and contribute to the development of standardised glaucoma care indicators.
