Systematic Review: Components of a Comprehensive Geriatric Assessment in Inflammatory Bowel Disease—A Potentially Promising but Often Neglected Risk Stratification

Abstract

Abstract Background The population of older patients with inflammatory bowel disease [IBD] is increasing. Patient age does not fully account for poor outcomes and its clinical utility for risk stratification is limited. Comprehensive geriatric assessment [CGA], comprising a somatic, functional, mental, and social assessment or frailty, could be a predictor tool. Aims To systematically review literature on the kind of components of a CGA being used in adult IBD patients and the association of these components with adverse health outcomes. Methods An electronic literature search was performed on January 16, 2018, using PubMed, Embase, Web of Science, the Cochrane Library, CENTRAL, Emcare, and PsycINFO. Longitudinal studies relating somatic, functional, mental, and social assessment or frailty to adverse health outcomes during follow-up in IBD patients were included. The Newcastle-Ottawa scale was used to assess individual study quality. Results Of 4080 identified citations, 27 studies were included, reporting 169 associations. Median sample size was 108 patients (interquartile range [IQR] 60–704). No studies performed subgroup analyses on older patients, and the highest mean age reported was 52.7 years. Somatic and functional assessments were used in three studies, mental in 24, and social in five. No study assessed cognitive status, functional performance, or frailty. In 62 associations [36.7%], components of a CGA were significantly associated with adverse health outcome measurements. Conclusions Components of a CGA were associated with adverse health outcomes in IBD patients, but older patients were under-represented. More studies among older patients with IBD are warranted to further establish the clinical impact of a CGA.
