Abstract

Background:

We assessed the ability of a telephone-administered cognitive screening test – Minnesota Cognitive Acuity Screen (MCAS) – to predict time to assisted living/nursing home placement (i.e. institutionalization) and homecare/institutionalization in healthy controls (HC), mild cognitive impairment (MCI), and Alzheimer's disease (AD).

Methods:

Participants (N = 146; HC = 37; MCI = 70; AD = 39) had baseline MCAS testing and were re-contacted over eight years for dates of starting homecare, institutionalization, and death. Occasionally, outcomes were obtained via medical records. Accounting for informative censoring due to death within a competing risks framework, Cox regression examined the associations of baseline MCAS performance with the start of (a) institutionalization and (b) homecare/institutionalization.

Results:

Hazard ratios (HR) captured the effect of a ten-point difference in baseline MCAS scores, corresponding to a change from the MCI/HC to AD/MCI boundaries. In unadjusted models, increased baseline cognitive impairment was associated with nearly two-fold increases in the hazard of institutionalization (HR = 1.81, 95% CI = 1.32, 2.48) and homecare/institutionalization (HR = 1.87, 95% CI = 1.44, 2.42). However, hazards were not proportional over time in models adjusting for sex. This was resolved when regressions were run for men and women separately. Both sexes showed significant increases in the hazard of institutionalization (Females: HR = 2.39, 95% CI = 1.53–3.74; Males: HR = 1.68, 95% CI = 1.02–2.76) and homecare/institutionalization (Females: HR = 2.31, 95% CI = 1.66, 3.21; Males: HR = 1.98, 95% CI = 1.32, 2.96) with increased impairment, although hazards were lower for males.

Conclusions:

Telephone-administered MCAS provides useful information about the risk of needing homecare assistance or institutionalization. It may be particularly useful when office/home visits are prohibitive but cognitive monitoring is indicated.
