Evaluation of a community-based integrated care model (CIE) for frail older people in rural Foshan, China: study protocol for a stepped-wedge cluster randomized controlled trial {1}

Abstract

Background While community-based eldercare has proven to be effective in qualitative studies, there is limited evidence on the effectiveness of this geriatric care model in rural communities where caring for older people is traditionally the responsibility of family members, but a formal long-term care was recently introduced in China. CIE is a rural community-embedded intervention using multidisciplinary team, to provide evidenced-based integrated care services for frail older people including social care services and allied primary healthcare and community-based rehabilitation services. Methods CIE is a prospective stepped-wedge cluster randomized trial conducted at 5 community eldercare centers in rural China. The multifaceted CIE intervention, guided by chronic care model and integrated care model, consists of five components: comprehensive geriatric assessment, individualized care planning, community-based rehabilitation, interdisciplinary case management, and care coordination. The intervention is rolled out in a staggered manner in these clusters of centers at an interval of 1 month. The primary outcomes include functional status, quality of life, and social support. Process evaluation will also be conducted. Generalized linear mixed model is employed for binary outcomes. Discussion This study is expected to provide important new evidence on clinical effectiveness and implementation process of an integrated care model for frail older people. The CIE model is also unique as the first registered trial implementing a community-based eldercare model using multidisciplinary team to promote individualized social care services integrated with primary healthcare and community-based rehabilitation services for frail older people in rural China, where formal long-term care was recently introduced.
