Maintenance of statin use over 3 years following acute coronary syndromes: a national data linkage study (ANZACS-QI-2)
Authors: Grey C et al.
Summary:
This study linked national hospitalisation, mortality and pharmaceutical
dispensing data for 11,348 patients aged 35–84 years discharged from a public hospital
with an acute coronary syndrome in New Zealand in 2007. Patients were followed for
3 years, to describe patterns of statin use and predictors of poor maintenance. Within
90 days of discharge, 83% had received a statin. The proportions of patients who were
adequately maintained on a statin (MPR ≥80%) were 69% in year 1 of follow-up, 67%
in year 2 and 66% in year 3. Patients taking statins prior to admission and those who
underwent a coronary procedure were 20–50% more likely to have a MPR ≥80% over
3 years than others. Patients aged 35–45 years and those of Māori or Pacific ethnicity were
13–25% less likely to have a MPR ≥80% than those aged 55–64 years and Europeans.
