Background/aims: We studied cognitive functioning 1 year after hospitalization (T2) in patients at least 65 years old without cognitive impairment at baseline (T1).
Methods: Cognition was assessed using the Mini-Mental State Examination (MMSE) at both time points. We included 211 (114 women) patients with a mean age of 78.3 (SD 7.0) years and an MMSE score of 24 and above.
Results: At T2, 69 (32.7%) patients had an MMSE score below 24. In participants with MMSE 24-26 at T1, cognitive decline was related to impaired physical self-maintenance, a decline in the performance of the instrumental activities of daily living, impaired hearing and less reading ability. In participants with MMSE 27-30, cognitive decline was associated with higher comorbidity (Charlson Index) and impaired physical self-maintenance and hearing.
Conclusion: A reduced functioning level and increased comorbidity predicted a decline in cognitive functioning.
