BACKGROUND

Older adults with cognitive impairment, no dementia (CIND) may have an increased risk of hospitalization before dementia develops. However, evidence on avoidable hospitalization and whether formal and informal care modify this risk remains limited.

RESEARCH QUESTIONS

•Is CIND associated with hospitalizations?

•Does CIND accelerate time to first hospitalization?

•Do formal and informal care attenuate these associations?

STUDY DESIGN

•Population-based cohort study using The Swedish National study on Aging and Care in Kungsholmen (SNAC-K)

•Baseline: 2001–2004; follow-up until 2016

EXPOSURE

•CIND: No dementia. Cognitive performance ≥1.5 SDs below age group-specific means in at least 1 of 5 cognitive domains

OUTCOMES

•First avoidable (AH) and non-avoidable (non-AH) hospitalization identified from the Swedish Patient Register

CARE USE

•Formal care: home social care and home healthcare

•Informal care: support from family, friends, or volunteers

RESULTS

•Among 3,009 dementia-free older adults (mean age 73.2y; 63.1% female), of whom 701 (23.3%) had CIND at baseline.

•CIND was associated with an 18% higher risk of AH (Table 1).

•Participants with CIND experienced hospitalization approximately 1 year earlier than those without CIND (Figure 1).

•CIND was associated with higher risk of AH among non-users, but lower risk among users of formal care (Table 2).

CONCLUSIONS

Older adults with cognitive impairment had higher risk of avoidable hospitalization. Formal care use appeared to attenuate this risk, highlighting the importance of accessible, coordinated care for cognitive impairment.
