    Backgroundpost-hospitalisation functional decline is a widely described phenomenon, yet factors related to new disability in instrumental activities of daily living (IADL) in previously independently functioning older adults are rarely studied.Objectiveto test whether change in cognitive status from admission to discharge during short-term acute-care hospitalisation is associated with the incidence of medium-term post-hospitalisation IADL dependency.Designprospective cohort study.Settinginternal medicine wards in two Israeli medical centres.Subjectstwo hundred and seventy-two hospitalised older adults (≥70) who were independent in self-care and mobility activities at admission, at discharge and 1 month after discharge, and who were independent in IADL pre-admission.Methodscognitive status was evaluated at admission and at discharge using Pfeiffer's Short Portable Mental Status Questionnaire (SPMSQ). One-month post-discharge, IADL was assessed using Lawton and Brody's scale by telephone.Resultsincidence of IADL dependency was 74/272 (27.2%). Controlling for length of stay, co-morbidities, re-hospitalisation and age, a one-unit decrease in SPMSQ score during hospital stay was associated with 1.57 higher odds (95% CI, 1.14-2.15) of post-hospitalisation new IADL dependency. The odds of new IADL dependency were also significantly higher in participants who were rehospitalised within the previous month (odds ratio = 2.65; 95% CI, 1.25-5.62).Conclusionsdecline in SPMSQ score during acute hospitalisation has a detrimental effect on functional decline after acute hospitalisation, defined by incidence IADL dependency. This finding emphasises the need to identify cognitive decline during hospitalisation to allow timely intervention to prevent post-discharge functional decline in this population.© The Author 2016.
