Validity of predischarge measures for predicting time to harm in older adults

Background. Concern is often expressed about the ability of persons with cognitive impairment to manage safely after discharge home from hospital. Measures validated for predicting safety are required. Purpose. The purpose of this study was to determine whether two predischarge functional measures were valid for predicting time to incident of harm after discharge. Method. Participants ( n = 47) were recruited from an inpatient rehabilitation unit. The Assessment of Motor and Process Skills (AMPS) and Cognitive Performance Test (CPT) were administered in hospital. Incident-of-harm outcome was measured by caregiver telephone questionnaire monthly for 6 months. Findings. Compared with all independent variables, AMPS Process scale was the best single predictor of time to incident of harm ( p = .01). CPT had a high specificity (91%) for identifying persons who did not have harm. Implications. Both AMPS and CPT demonstrated predictive validity for harm outcome over less predictive variables, such as comorbidities and activities-of-daily-living burden of care.
