[Geriatric syndromes, multimorbidity and geriatric psychiatry; an integrated perspective]. / Geriatrische syndromen, multimorbiditeit en ouderenpsychiatrie; een geïntegreerd perspectief.

ABSTRACT

BACKGROUND: The prevalence of geriatric syndromes, frailty and multimorbidity increases in older age, with a negative impact on health outcomes. Little is known on these problems in older adults with psychiatric disorders. AIM: To evaluate the prevalence of geriatric syndromes and multimorbidity in older adults with psychiatric disorders and their impact on treatment outcomes. METHOD: We conducted a pilot study and a case-control study on older adults with medically insufficiently explained symptoms, a prospective cohort study in older adults, acutely admitted to psychiatric wards and a systematic review to evaluate whether geriatric syndromes were considered in RCTs on depression treatment. RESULTS: Unexplained symptoms were often accompanied by frailty, multimorbidity and psychiatric disorders. Older adults who were acutely admitted to psychiatric wards had a high level of multimorbidity, about half of them were frail, and a third undernourished. Frailty and multimorbidity were independent predictors for not being discharged to their own home. Frailty also strongly predicted the 5-year mortality rate. Geriatric syndromes were hardly considered in study design or as secondary outcome in treatment studies on depression in older adults. CONCLUSION: Overall, geriatric problems are highly prevalent among older adults with psychiatric disorders and have a relevant prognostic impact. The complexity of older psychiatric patients is probably best addressed by interdisciplinary, integrated diagnostic and treatment trajectories.
