Aim: To investigate if older adults' performance on the Mini Mental Status Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) subscales were associated or predictive of their estimated length of hospital stay (ELOHS). Methods: Twenty participants (11 males, 9 females, ̄x age 82.05 years, SD = 6.93) were recruited from a geriatric evaluation and management ward in an Australian hospital. Participants' cognitive abilities were assessed using the MMSE and MoCA. Spearman's rho correlations and linear regression analyses with and without bootstrapping were completed. Results: Only the MMSE Orientation subscale was significantly associated with the participants' ELOHS. The MMSE Orientation subscale (Adjusted R2 = .52, F(1, 18) = 20.36, p < .01), and MoCA Orientation subscale (Adjusted R2 = .39, F(1, 18) = 13.15, p< .01) were found to be predictive of participants' ELOHS after bootstrapping. Conclusion: Participants' MMSE and MoCA Orientation subscale scores may be useful in estimating patients' ELOHS. Further studies are recommended to confirm these findings.
