To identify and categorize home- and community-based services used by older adults and the distribution of their utilization, and to examine their utilization patterns in terms of region, time trends, and older adults' characteristics.

Systematic review and meta-analysis.

We conducted a systematic search of six databases for studies published up to January 12, 2023, and performed meta-analyses and subgroup analyses to identify the utilization of home- and community-based services and analyze utilization patterns concerning region, time trends, and individual characteristics.

We included 42 studies from 10 countries worldwide, involving a total of 2,942,069 older adults. Home- and community-based services were grouped into three categories: health services, social services, and family caregiver services. Regional differences were consistently evident across all three categories of services, reflecting diverse patterns of home- and community-based service adoption worldwide. Notably, there was a significant increase in the utilization of social services, as distinct from health services and family caregiver services, during the post-2010 period (2010–2018) in comparison with the pre-2010 period (before 2010). In addition, age and cognitive function also played an important role in the utilization of home- and community-based services.

These findings highlight the importance of tailoring home- and community-based services to specific populations and understanding the needs of older adults over time. Further research should be undertaken to gain a deeper understanding of the reasons behind these variations and differences and to provide more targeted and effective services to older adults worldwide.
