A randomised controlled trial of the outcome of health assessment of people aged 75 years and over

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 th eir 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 partic ipants was drawn from practice age-sex registers. Data were collected in in itial visits between 1 August 1998 and February 1999, then in follow-up vis its 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 re ported 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; p sychological (including cognitive) function; falls; and admission to instit ution. Results: There were no significant differences between the control and inte rvention groups at follow-up in the number of problems, the number of parti cipants with problems, or mortality, In the intervention group, there was s ignificant improvement in self-rated health, geriatric depression score (GD S 15), and number of tails. 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.
