Objectives:
Managing older patients with surgical conditions is a major challenge for hospitals. There is therefore a growing interest in providing geriatric perioperative services. The aim of this systematic review and meta-analysis was to characterize and assess the impact of targeted perioperative geriatric interventions on clinical outcomes of older adults admitted to nonorthopedic surgical teams.
Design, Setting And Participants:
A systematic review and meta-analysis of studies of perioperative geriatric interventions in older adults hospitalized under nonorthopedic surgical teams.
Methods:
Ovid MEDLINE, EMBASE, PsycINFO, Scopus, Cochrane Central Register of Controlled Trials, CINAHL, and trial registry databases were searched. Primary outcomes were change in functional status and length of stay (LOS).
Results:
Fifteen randomized controlled trials (RCTs) and 9 prospective before-and-after studies met the inclusion criteria (n = 3026 participants). Perioperative geriatric interventions included preoperative comprehensive geriatric assessment and management (CGA) (5 studies), multicomponent inpatient geriatric programs (8 studies), cognitive training (1 study), exercise (5 studies), and prehabilitation (5 studies). Exercise therapy [mean difference (MD) -1.90, 95% confidence interval (CI) -3.01, -0.80], multicomponent inpatient geriatric programs (MD -1.98, 95% CI -3.09, -0.88), and prehabilitation (MD -1.32, 95% CI -2.75, 0.11) reduced LOS. Functional decline was highly heterogeneous, with 4 of 8 studies reporting significantly less functional decline. Geriatric perioperative interventions reduced complications [exercise therapy risk ratio (RR) 0.74, 95% CI 0.48, 1.15; prehabilitation RR 0.61, 95% CI 0.47, 0.80] and delirium (multicomponent inpatient geriatric programs RR 0.49, 95% CI 0.27, 0.90; preoperative CGA RR 0.54, 95% CI 0.33, 0.89). There was no significant impact on mortality or readmissions.
Conclusions And Implications:
Perioperative geriatric interventions targeted at older nonorthopedic surgical patients improve some clinically relevant outcomes. There is a need for these interventions to be further evaluated in high-quality studies, and future research should explore how to effectively implement these interventions within complex health care systems.
