title: Prevalence of hip problems in the population aged 55 years and over: access to specialist care and future demand for hip arthroplasty.
abstract: To determine the prevalence of hip problems in the population aged 55+, a postal questionnaire was sent to a multistage stratified random sample of residents of a health district with an over-55 population of 210,000. An initial four page postal questionnaire produced an 86% response rate from 18,827 eligible cases. A subsequent detailed questionnaire (with a response rate of 78%) then determined the prevalence of severe pain and severe disability amongst those with hip problems. The prevalence of those with existing hip replacements is estimated at 32.1/1000 (95% CI 29.5-34.9). An estimated 13.5/1000 (95% CI 12.4-14.7/1000) displayed levels of pain and disability consistent with a current need to consider arthroplasty. In addition, it appears that the over 75s are less likely to have access to appropriate surgery. Unless health authorities and, increasingly, general practitioners consider purchasing more hip replacements, the prevalence pool of those who could benefit will inexorably rise.
