Summary
The study estimates England needs 46,600 primary total hip replacements annually. Current provision is around 43,500, suggesting demand for hip surgery is achievable with agreed criteria.
Area of Science:
- Orthopedic Surgery
- Epidemiology
- Public Health
Background:
- Significant unmet demand exists for elective surgeries like total hip replacement (THR) globally.
- Estimating population needs for THR is crucial for healthcare planning in England.
Purpose of the Study:
- To determine the population requirement for primary total hip replacement in England.
- To assess the gap between estimated need and current provision of THR.
Main Methods:
- Cross-sectional study of 28,080 individuals aged 35+ in Avon and Somerset, UK.
- Two-stage disease identification: screening questionnaire and clinical examination.
- Statistical modeling used to estimate incident disease and surgical requirement based on pain, function, comorbidity, and patient preference.
Main Results:
- Prevalence of hip disease requiring surgery was 15.2 per 1000 (aged 35-85).
- Estimated annual incidence of hip disease requiring surgery was 2.23 per 1000.
- Total estimated annual requirement for THR in England is 46,600 operations, compared to 43,500 provided.
Conclusions:
- The findings suggest that meeting the demand for total hip replacement is feasible.
- Agreed-upon surgical criteria can guide the satisfaction of THR needs.
