Sleep disturbances and sleep quality among individuals diagnosed with osteoarthritis: A systematic review protocol

Background: Osteoarthritis (OA) is a leading cause of chronic pain and disability, particularly affecting weight-bearing joints such as knees and hips. While the impact of knee and hip OA on physical function is well-recognized, there is increasing concern about how these conditions influence sleep disturbances and overall sleep quality. Objectives: This systematic review will assess the level of sleep disturbances, associated factors, and various aspects of sleep quality such as type, pattern, duration, onset time, and efficiency as well as to evaluate effective interventions for improving sleep among patients diagnosed with knee and hip osteoarthritis (KHOA). Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA- P) guidelines, this study aims to assess and consolidate data on sleep issues and quality in knee or hip osteoarthritis. It will be conducted across electronic databases, including Medline via PubMed, CINAHL via EBSCO, EMBASE, Scopus, ScienceDirect, and Web of Science. Additionally, grey literature will be explored using Google Scholar, ProQuest and Sodhganga. Expected outcomes: This study will provide a comprehensive understanding of the extent of sleep issues and disorders, characteristics of sleep quality as an impact of KHOA. The findings will be valuable for policymakers and healthcare providers in developing effective strategies to enhance the quality of life for individuals with OA who experience sleep disturbances.
