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.
