The Effect of Caregiver-Facilitated Pain Management Interventions in Hospitalized Patients on Patient, Caregiver, Provider, and Health System Outcomes: A Systematic Review.

Abstract

Alternative pain management interventions involving caregivers may be valuable adjuncts to conventional pain management interventions. Use systematic review methodology to examine caregiver-facilitated pain management interventions in a hospital setting and whether they improve patient, caregiver, provider, or health system outcomes. We searched MEDLINE, EMBASE, PsycINFO, CINAHL, and Scopus databases from inception to April 2020. Original research on caregiver-facilitated pain management interventions in hospitalized settings (i.e., any age) were included and categorized into three caregiver engagement strategies: inform (e.g., pain education), activate (e.g., prompt caregiver action), and collaborate (encourage caregiver's interaction with providers). Of 61 included studies, most investigated premature (n = 27 of 61; 44.3%) and full-term neonates (n = 19 of 61; 31.1%). Interventions were classified as activate (n = 46 of 61; 75.4%), inform-activate-collaborate (n = 6 of 61; 9.8%), inform-activate (n = 5 of 61; 8.2%), activate-collaborate (n = 3 of 61; 4.9%), or inform (n = 1 of 61; 1.6%) caregiver engagement strategies. Interventions that included an activate engagement strategy improved pain outcomes in adults (18-64 years) (e.g., self-reported pain, n = 4 of 5; 80%) and neonates (e.g., crying, n = 32 of 41; 73.0%) but not children or older adults (65 years and older). Caregiver outcomes (e.g., pain knowledge) were improved by inform-activate engagement strategies (n = 3 of 3). Interventions did not improve provider (e.g., satisfaction) or health system (e.g., hospital length of stay) outcomes. Most studies were of low (n = 36 of 61; 59.0%) risk of bias. Caregiver-facilitated pain management interventions using an activate engagement strategy may be effective in reducing pain of hospitalized neonates. Caregiver-facilitated pain management interventions improved pain outcomes in most adult studies; however, the number of studies of adults is small warranting caution pending further studies.
