Studies were identified by searching Medline (1975 to May 2000), HealthSTAR (1975 to May 2000), and the Cochrane Database of Systematic Reviews (2000, issue 1). Bibliographies of relevant articles were also searched for additional references.
Studies published in English or French were selected if they were original research, randomised or non-randomised controlled trials of a geriatric post discharge service, and ≥1 measure of mental state was reported.
Data were extracted on country, study design, sample size, subject selection, key components of the intervention, duration of follow up, quality of the study, and outcomes. Outcomes included depression, morale, life satisfaction, contentment, emotional function, social activities, and self perceived health or cognition.
11 randomised controlled trials (3814 patients, ≥60 y of age in 9 trials) met the selection criteria. Interventions included patient assessment and follow up by a multidisciplinary team (physician, nurse, physiotherapist, occupational therapist, social worker or support workers) (5 trials), patient assessment and follow up by a nurse (3 trials), help provided by a home aide or attendant (2 trials), and visitation by a volunteer (1 trial). Small improvements in morale, contentment, emotional function, life satisfaction, and self perceived health were reported in 3 trials. The intervention and control groups did not differ for any of the outcomes in 8 trials.
In elderly people, geriatric health services after discharge do not improve mental state.
An impaired mental state can adversely affect the patient's ability to function, and also affects whether a caregiver can look after the patient. This review by Cole has examined the mental state (ie, cognition, depression, and anxiety) of geriatric patients after discharge from medical units. Of 98 potential references found through searching computer databases, 11 included some measure of mental state upon follow up after discharge. Little impact on mental state at post discharge follow up was noted from the varying outcome measures used in the 11 trials. The need for further and more extensive research in this area was suggested.
Depression and cognitive impairment have been found to be main predictors of morbidity and mortality in a number of medical conditions, particularly in the elderly. Death due to cardiac disease or stroke occurs more often when depression is present.1, 2 Cognitive impairment is a common sequela of coronary artery bypass surgery.3
This study suggests the need for increased attention to mental state measures in outcome research of hospitalised geriatric patients both during hospitalisation and at post discharge visits.
