Background Although many studies describe benefits from thecomprehensive assessment of elderly patients by an interdisciplinaryteam (comprehensive geriatric assessment), the most supportiveevidence for the process has come from programs that rely onspecialized inpatient units and long hospital stays. We examinedwhether an inpatient geriatric consultation service might alsobe beneficial in a trial involving four medical centers of agroup-practice health maintenance organization (HMO).
Methods We conducted a randomized clinical trial with 2353 hospitalizedpatients 65 years of age or older in whom at least 1 of 13 screeningcriteria were present: stroke, immobility, impairment in anybasic activity of daily living, malnutrition, incontinence,confusion or dementia, prolonged bed rest, recent falls, depression,social or family problems, an unplanned readmission to the hospitalwithin three months of a previous hospital stay, a new fracture,and age of 80 years or older. Of the 1337 patients assignedto the experimental group, 1261 (94 percent) received a comprehensivegeriatric assessment in the form of a consultation, with limitedfollow-up; the 1016 patients assigned to the control group receivedusual care. The functional and health status of the patientswas measured at base line and 3 and 12 months later; survivalwas assessed at 12 months. Subgroups of patients who might bepresumed to benefit from comprehensive assessment were alsostudied.
Results The survival rate at 12 months was 74 percent in theexperimental group and 75 percent in the control group. At baseline, 3 months, and 12 months the scores of the two groups onmeasures of functional and health status were similar. The analysisof 16 subgroups did not identify any with either clearly improvedfunctional status or improved survival.
Conclusions In this HMO, comprehensive geriatric assessmentby a consultation team, with limited follow-up, did not improvethe health or survival of hospitalized patients selected onthe basis of screening criteria.
