Sociodemographic Disparities in the Use of Hospice by U.S. Nursing Home Residents: A Systematic Review.

Hospice can improve end-of-life (EOL) outcomes in U.S. nursing homes (NHs). However, only one-third of eligible residents enroll, and substantial variation exists within and across NHs related to resident-, NH-, or community-level factors. We conducted a review of English-language, peer-reviewed articles 2008 to 2023 describing this variation in NH hospice use to characterize disparities and inform educational and quality initiatives to improve EOL care in NHs. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We screened 1595 records, reviewed 82 articles and included 13 articles. Eleven used pre-2009 data. Six evaluated national data and 7 used regional (n = 1), state (n = 4), or local (n = 2) data. One assessed hospice referral, 10 hospice use, and 3 length-of-stay. Twelve conducted regression analyses; 1 stratified by race, another evaluated interaction terms, and a third compared racial differences within-and between-facilities. Unadjusted and adjusted differences were evaluated by resident race-and-ethnicity (n = 6 unadjusted, n = 10 adjusted, respectively), sex (n = 5, n = 9), or payor (n = 1, n = 4), or by NH race-mix (n = 1, n = 2), ownership (n = 1, n = 7), payor-mix (n = 1, n = 5), or urban/rural location (n = 1 adjusted). Unadjusted differences showed lower hospice use by Non-White residents and varied results by sex. Studies adjusting for resident-, NH-, and community-level factors found lower hospice use among male residents, Black/Non-White residents, and residents of rural NHs, with mixed results by payor and ownership. Results were mixed for hospice referral and length-of-stay. These findings suggest complex influences on NH hospice use. Further study is warranted to identify targets for improving hospice access.
