All-Cause Acute Illness Hospitalisations in the Preceding Two Years Are Associated With Cognitive Decline in Older Adults: The Sydney Memory and Ageing Study.

ABSTRACT:

Objectives

Emerging evidence suggests all-cause acute hospitalizations are associated with cognitive decline, rather than being associated only with specific inpatient contexts (surgery, critical care and delirium). This study clarifies this association in an Australian context.

Methods

This study is a secondary analysis of four biennial waves of prospective population-based neuropsychological measures from 1026 functionally independent Sydney Memory and Ageing Study participants aged 70-90 years at baseline, and contemporaneous probabilistically-linked hospitalization data. The outcome measures were global cognition baseline (intercept) and change (slope) and their associations with hospitalization episodes and cumulative length of stay (cLOS) variables in five consecutive
