OBJECTIVES: To measure the outcomes of a health assessment, conducted by a nurse, of people aged 75 years and older (75+HA) living independently in their own homes. DESIGN: Randomised controlled trial (RCT). SETTING: A convenience sample of six general practices within the Adelaide Western Division of General Practice (AWDGP). A random sample of 100 participants was drawn from practice age-sex registers. Data were collected in initial visits between 1 August 1998 and February 1999, then in follow-up visits one year later. PARTICIPANTS: Participants were aged 75 years and over on 1 August 1998 and living independently in the community. 145 eligible patients were invited to join the study, and 100 of these consented to enrol (69%). INTERVENTION: A 75+HA conducted in the participant's home by a nurse and reported to their usual general practitioner. MAIN OUTCOME MEASURES: Primary: number of problems in each group; number of participants with problems; and mortality. Secondary: physical function; psychological (including cognitive) function; falls; and admission to institution. RESULTS: There were no significant differences between the control and intervention groups at follow-up in the number of problems, the number of participants with problems, or mortality. In the intervention group, there was significant improvement in self-rated health, geriatric depression score (GDS 15), and number of falls. CONCLUSIONS: This RCT has not demonstrated improvement in health status of the intervention group which received a 75+HA compared with a control group left to usual care.
