Summary of current literature on prediction of recovery potential

A total of 26 of 27 studies addressed the recovery of function after functional decline, most often measured with questionnaires before and after the stressor, but they varied in study design. The stressors studied were elective surgery, hip/femur fracture, any acute disease or injury requiring hospital admission, cancer/chemotherapy, or unspecified. All studies operationalized resilience using a definition‐driven approach.11 Recovery was typically dichotomized (yes/no), with a large variety of definitions. Reported predictors of recovery were functional status, cognition, nutritional status, frailty or multimorbidity, hand grip strength, social support, and depressive symptoms. Three studies collected daily in‐hospital questionnaires about mobility23, 24 or daily step counts with wearable technology,25 providing more detailed information about the course of recovery. One study combined up to 296 patient characteristics derived from health record data in a machine‐learning modeling approach and showed that this method can predict with a reasonable accuracy whether recovery of functional status after hospitalization is to be expected.59
