Variation in quality of care by medical institute level in China: a systematic review protocol

Abstract

IntroductionQuality variation has been widely witnessed and discussed in China. However, limited evidence reveals quality gaps by the medical institute level, especially between hospitals and primary care institutes. This systematic review will synthesise the available evidence on quality variation between medical institutes at different levels in China. By adopting a quality framework, we will also explore the detailed domains (structure, process and outcomes) and dimensions (safety, effectiveness, timeliness, patient-centredness, efficiency, integration and equity) of quality gaps.Methods and analysisAn extensive literature search will be conducted on eight key electronic databases: MEDLINE, Web of Science, Cochrane Library, Scopus, EMBASE, ProQuest, China National Knowledge Infrastructure and WANFANG database. The Grey Matter Checklist will be used to screen relevant grey literature. The publication time limit should be before 31 December 2022 when we plan to conduct a literature search. All kinds of studies that revealed the quality difference between medical institutes at different levels will be included, no matter if quality improvement intervention is involved. All quality measures and indicators will be recorded and sorted into appropriate domains and dimensions. For those studies that took the completion rate of standard operations to assess the quality, we will also record the name of the clinical pathways, guidelines or checklists used. Two reviewers will independently perform the study selection, data extraction and quality assessment process. A narrative or quantitative synthesis will be performed based on the available data.Ethics and disseminationEthics approval is not applicable. The results of this study will be submitted to a widely accepted peer-review journal. The findings will also be used to inform administration about quality gaps by different medical institute levels and, therefore, help them to design policies that will minimise the quality variation.PROSPERO registration numberCRD42022345933.
