Aims: To determine patterns of alcohol use and misuse among community-dwelling people aged 65 years and over in Christchurch and to assess how often this comes to medical attention.
Methods: A cross-sectional survey of alcohol use and misuse was conducted followed by a self-administered postal survey among non- respondents. General practitioners (GPs) of the respondents completed a self-administered questionnaire on patients' alcohol use and misuse.
Results: The response rate was 58% (141/243). The prevalence of hazardous alcohol consumption in the past twelve months (AUDIT cut-off score 8 or more) was 9.9% (95% CI = 4.9-14.9) and the prevalence of lifetime alcohol dependence using DSM-IV diagnostic criteria was 24.8% (95% CI = 17.6-32.0). Men were more likely than women to report lifetime dependency and current hazardous patterns. The response rate among GPs was 77.7% (108/139). None of the GPs identified or diagnosed alcohol problems in the past twelve months among this group and reported a history of alcohol problems in only four (4.0%) patients. Those with current hazardous patterns of alcohol use were twice as likely to be admitted to hospital (RR=2.4; 95% CI 1.2-5.1) but significantly less likely to visit their GPs in the previous twelve months (RR=0.55; 95% CI 0.7-1.1).
Conclusion: A significant proportion of community-dwelling elderly people reported patterns of alcohol consumption that put them at risk of future damage to physical or mental health. Hazardous drinkers were less likely to visit their GPs and only in a few cases, were GPs aware of such potential problems.
