| Abstract | Introduction: The present real-world analysis aims to compare the drug utilization, hospitalizations and direct healthcare costs related to the use of single-pill combination (SPC) or free-equivalent combination (FEC) of perindopril and bisoprolol (PER/BIS) in a large Italian population. Methods: This observational retrospective analysis was based on administrative databases covering approximately 7 million subjects across Italy. All adult subjects receiving PER/BIS as SPC or FEC between January 2017-June 2020 were included. Subjects were followed for 1 year after the first prescription of PER/BIS as FEC (± 1 month) or SPC. Before comparing the SPC and FEC cohorts, propensity score matching (PSM) was applied to balance the baseline characteristics. Drug utilization was investigated as adherence (defined by the proportion of days covered, PDC) and persistence (evaluated by Kaplan-Meier curves). Hospitalizations and mean annual direct healthcare costs (due to drug prescriptions, hospitalizations and use of outpatient services) were analyzed during follow-up. Results: The original cohort included 11,440 and 6521 patients taking the SPC and FEC PER/BIS combination, respectively. After PSM, two balanced SPC and FEC cohorts of 4688 patients were obtained (mean age 70 years, approximately 50% male, 24% in secondary prevention). The proportion of adherent patients (PDC ≥ 80%) was higher for those on SPC (45.5%) than those on FEC (38.6%), p < 0.001. The PER/BIS combination was discontinued by 35.8% of patients in the SPC cohort and 41.7% in the FEC cohort (p < 0.001). The SPC cohort had fewer cardiovascular (CV) hospitalizations (5.3%) than the free-combination cohort (7.4%), p < 0.001. Mean annual total healthcare costs were lower in the SPC (1999€) than in the FEC (2359€) cohort (p < 0.001). Conclusion: In a real-world setting, patients treated with PER/BIS SPC showed higher adherence, lower risk of drug discontinuation, reduced risk of CV hospitalization, and lower healthcare costs than those on FEC of the same drugs. |
