  2. Definition

    This phenotype identifies individuals with evidence of sarcopenia recorded in routinely collected electronic health records. Sarcopenia is a recognised risk factor for falls through reduced muscle mass, strength, and physical performance. The phenotype is intended for use in studies of falls risk assessment, epidemiology, risk prediction, and evaluation of fall prevention interventions. Case ascertainment is based on diagnostic codes recorded in primary and/or secondary care electronic health records.
