Statin prescription among patients with type 2 diabetes in Botswana: findings and implications
Abstract Background There is evidence of statin benefit among patients with diabetes regardless of their cholesterol levels or prior cardiovascular disease history. Despite the evidence, there is under-prescription of statins in clinical practice. This study aimed to assess statin prescriptions and associated factors among patients with type 2 diabetes in Botswana. Methods The study was a secondary data analysis of 374 randomly selected type 2 diabetes patients at a specialised diabetes clinic at Gaborone Botswana. We assessed the proportion of statin-eligible patients who are prescribed statins and evaluated the adjusted associations between various factors and statin prescription. Results Overall, 356 (95.2%) participants were eligible for a statin prescription. Clinicians prescribed statins in 162 (45.5%%; 95% confidence interval [CI]: 40.4% - 50.7%)) of eligible participants, and only one (5.5%) ineligible participant. The probability of statin prescription was high in participants with high baseline low-density lipoprotein cholesterol (risk ratio [RR]: 1.49; 95%CI: 1.17 - 1.89), increasing duration of diabetes (RR: 1.01; 95%CI 1.00 - 1.03) and the presence of chronic kidney disease (RR: 1.35; 95%CI: 1.06 - 1.74). Conclusion Most patients with type 2 diabetes are not receiving statins. Clinicians did not consider most guideline-recommended indications for statin prescription. The findings call for improvement in diabetes quality of care by implementing evidence-based guideline recommendations. Key words: statin, type 2 diabetes mellitus, prescription and Botswana
