The CareWell in Hospital questionnaire: a measure of frail elderly inpatient experiences with individualized and integrated hospital care.

Given our aging society with an increasing number of frail elderly patients, we must provide integrated care tailored to their complex needs regarding health and well-being. The aim of this study was to develop and validate a questionnaire designed to assess how frail hospitalized elderly patients experience several important aspects of individualized and integrated care. An 8-item questionnaire was developed using input from a panel representing the target group and administered to patients age ≥70 years from surgical, medical, and geriatric departments to measure data characteristics, internal consistency, test-retest reliability, construct validity, and responsiveness. A total of 470 questionnaires were returned, including 78 for test-retest reliability. Data were missing from 1.7% to 7.0% within the individual questions. The percentage of questions answered with "don't know" ranged 3.8% to 21.9%. Cronbach's α for internal consistency was 0.70. Test-retest intraclass correlation was 0.75. Achievement of goals during the hospital stay was significantly correlated with the questionnaire score. Scores did not differ significantly between departments or between the before and after measurements related to an innovative intervention study in healthcare delivery. The CareWell in Hospital questionnaire has good content validity, internal consistency, and test-retest reliability and warrants further research to explore responsiveness.
