Eleven-Year Trends in Lipid-Modifying Medicines Utilisation and Expenditure in a Low-Income Country: A Study from the Republic of Srpska, Bosnia and Herzegovina

Trends in Lipid-Lowering Agent Consumption in Croatia: A 25-Year Observational Study

Cardiovascular diseases are the leading cause of mortality worldwide, with dyslipidemia as a major modifiable risk factor. This study aimed to assess 25-year trends in lipid-lowering agent consumption in Croatia from 2000 to 2023. We conducted a population-based analysis using IMS and IQVIA databases, calculating drug utilization in defined daily doses per 1000 inhabitants per day (DDD/1000) and evaluating financial expenditures and prescribing patterns. Over the study period, total lipid-lowering drug consumption increased more than 30-fold, from 4.91 DDD/1000 in 2000 to 152.56 DDD/1000 in 2023. Statins, particularly atorvastatin and rosuvastatin, drove this trend, while the uptake of PCSK9 inhibitors and ezetimibe reflected an evolving therapeutic landscape. Financial expenditures peaked in 2010, declined until 2015, and rose again by 2023, with average drug prices per DDD decreasing significantly. The observed increase in lipid-lowering therapy correlated with enhanced adherence to international guidelines and expanded patient access. However, administrative barriers and restrictive reimbursement policies continue to limit optimal utilization of newer agents. These findings underscore the importance of evidence-based policy development to address clinical inertia and improve cardiovascular outcomes in Croatia.

Evaluation of Statin Indication and Dose Intensification Among Type 2 Diabetic Patients at a Tertiary Hospital

Background

Diabetes mellitus (DM) increases cardiovascular disease (CVD) incidence and mortality. While guidelines endorse statin use in type 2 DM (T2DM) to mitigate cardiovascular risks and mortality, challenges like statin initiation and prompt treatment adjustments affect patient outcomes. This study aimed to assess the appropriateness of indications for and dose intensification of statin therapy among T2DM patients at Tikur Anbessa Specialized Hospital (TASH).

Methodology

A hospital-based cross-sectional study was conducted from April 1 to June 30 2020. In total, 405 T2DM patients were selected using a systematic random sampling technique. The data were analyzed using SPSS version 26.0. An adjusted odds ratio (OR) was used and a 95% confidence interval (CI) and p-values of <0.05 were utilized to determine statistical significance.

Results

Of the total 405 participants, 346 (85.4%) started taking statins for primary or secondary prevention purposes. Indication for statin use was appropriate in 96.2% patients, while for 216 (62.4%) patients their doses were appropriately intensified. Predictors of the inappropriateness of statin use were an atherosclerotic cardiovascular disease (ASCVD) score of ≥7.5% (AOR=0.28; 95% CI: 0.102-0.738, p=0.01), the presence of dyslipidemia (AOR=4.48; 95% CI: 1.85-10.84; p=0.001), initiation of aspirin therapy (AOR=3.7; 95% CI: 1.522-9.144; p=0.004), and an LDL-cholesterol level of 70-189 mg/dL (AOR=0.124; 95% CI: 0.042-0.365; p=0.001). DM duration of ≥10 years (AOR=2.51; 95% CI: 1.35-4.66, p=0.004), male gender (AOR=2.04; 95% CI: 1.16-3.58, p=0.013), age ≥65 years (AOR=2.15; 95% CI: 1.23-3.75, p=0.007) and uncontrolled blood pressure (AOR=2.09; 95% CI: 1.07-4.08, p=0.031) were associated with inappropriate statin intensification.

Conclusion

The study found that indication of statins was optimal and about two-thirds of patients had their doses appropriately intensified. Monitoring is needed to avoid inappropriate intensification of statin therapy, particularly in patients with longer diabetes duration, those of male gender and advanced age, and those with uncontrolled blood pressure.
