Over one fifth of patients were prescribed a lipid‐lowering medication, and two fifths of these prescriptions were for primary prevention of cardiovascular disease. Patients in the highest quartile of Charlson Comorbidity Index score were 4.6 (CI 2.06–10.09) times more likely to be prescribed a lipid‐lowering medication than those in the lowest quartile.</p> </sec> <sec id="imj12340-sec-0005" sec-type="section"> <title>Conclusions</title> <p>Polypharmacy is prevalent for this group of patients, placing them at high risk of drug‐drug and drug‐host interactions. Prescribing may be driven by risk factors and disease guidelines rather than a rational, patient‐centred approach.</p> </sec> </abstract>
