Muscle strength is longitudinally associated with mobility among older adults after acute hospitalization

This database is a subset based on the Hospital ADL database and represents data from 391 acute hospitalised older adults. Directly identifying information was removed. Data collection took place between September 2015 and June 2017 in six hospitals in the Netherlands. The study was approved by the Institutional Review board of the Amsterdam UMC, location AMC in the Netherlands (Protocol ID: AMC2015_150) and performed according to the Dutch Medical Research Involving Human Subjects Act and principles of the Declaration of Helsinki (1964). Local approval was additionally provided by all participating hospitals. Data were collected at four timepoints: admission to the hospital, discharge from hospital, one month post-discharge and three months post-discharge. Muscle strength was measured by the maximal Handgrip strength (in kg) and mobility were measured with the de Morton Mobility Index (DEMMI) (in points). Demographic and psychosocial data (such as age, living situation body mass index, diagnosis, comorbidity, fatigue, depressives symptoms, fear of falling, nutrition) was collected at baseline. Detailed information on the protocol of the Hospital ADL study is published previously (Reichardt et al. 2016). Because of the sensitive nature of the data, the dataset (SPSS file and syntax) is confidential and will be shared only under strict conditions.
