Statin prescribing in Nottingham general practices: a cross-sectional study

Area of Science:

• Public Health
• Cardiovascular Epidemiology
• Health Services Research

Background:

• Deprivation is a key indicator of population cardiovascular morbidity and the need for statin therapy.
• Understanding variations in statin prescribing is crucial for equitable cardiovascular disease management.
• Nottingham general practices were studied to assess the impact of socioeconomic deprivation on prescribing patterns.

Purpose of the Study:

• To investigate the relationship between socioeconomic deprivation and statin prescribing rates in Nottingham general practices.
• To determine if areas with higher cardiovascular disease prevalence receive adequate statin treatment.
• To identify factors influencing statin prescription variations.

Main Methods:

• A cross-sectional study analyzed statin prescribing data from 118 Nottingham general practices in 1996.
• Prescribing rates were correlated with practice deprivation indices (Townsend score, Jarman UPA(8)) using 1991 Census data.
• Statistical models adjusted for practice characteristics, cardiovascular prescribing costs, and hospital admission data.

Main Results:

• Statin prescribing varied significantly across practices, ranging from 0 to 14.1 'statin-years' per 1000 patients (aged 35-69).
• A significant inverse relationship was found between statin prescribing rates and practice deprivation levels (p < 0.0001).
• Deprivation, measured by the Townsend index, explained 13-19% of the variability in statin prescribing; other factors showed no significant association.

Conclusions:

• Practices serving more deprived populations, with higher cardiovascular disease prevalence, prescribed fewer statins.
• This suggests a potential under-treatment of cardiovascular risk in more deprived areas.
• Targeted interventions may be necessary to improve statin uptake among at-risk individuals in deprived communities.
