Treatment Pattern of Heart Failure Patients in Sweden During 2021-2023 in Relation to Updated Treatment Recommendations.

Abstract

Background: In early 2022, new treatment recommendations for heart failure (HF) were introduced in Sweden.

Objective: This study aims to evaluate and analyze the pharmaceutical treatment patterns of HF patients over time in Sweden, in relation to the updated treatment recommendations.

Methods: This observational study is based on registry data. The study population consisted of patients ≥18 years old who, at any time between 2017 and 2023, had an HF diagnosis, defined using ICD-10 code I50 (n = 212,757). Descriptive statistics were presented for the study population. Based on data from the national drug prescription registry, the treatment patterns between 2021 and 2023 were analyzed using biannual datasets before and after the introduction of treatment recommendations.

Results: The mean age of the study population was 79 years and 56% were men. The utilization of quadruple therapy and SGLT2 inhibitors, both as monotherapy and in combination, increased over time, with a rising trend already apparent prior to the introduction of the updated treatment recommendations. At the end of 2023, about 30% of the incident HF population had at least tried quadruple therapy. Furthermore, a growing number of diverse treatment pathways among HF patients was observed over time, which may indicate an increased consideration for individualized treatment.

Conclusions: Even though the implementation of the treatment recommendations for HF is not yet optimal, this study found a notable adoption of quadruple therapy in Sweden. There was an increased use of SGLT2 inhibitors and quadruple therapy, beginning even before the introduction of the updated Swedish treatment recommendations.
