Abstract
Purpose Poor persistence to antihypertensive therapy is an important cause of treatment failure. Investigating persistence is especially important in countries with a high cardiovascular mortality, like Lithuania. The aim of this study was to describe the antihypertensive treatment at initiation, to determine the percentage of patients not being persistent with antihypertensive treatment after 1 year and to explore factors associated with non-persistence. Methods In this cohort study, data on dispensed prescription medicines from the Lithuanian National Health Insurance Fund (NHIF) were used. All adult patients with a diagnosis of hypertension having first antihypertensive dispensed in 2018 were included. Descriptive statistics was used to determine the number of patients started with monotherapy and combination therapy. Treatment choice by Anatomical Therapeutic Chemical (ATC) and number of active pharmaceutical ingredient (API) was described. Non-persistence was assessed using the anniversary method. Multivariate logistic regression was used to explore factors associated with non-persistence. Results A total of 72,088 patients were included into the study, 56% started on monotherapy treatment, with 49% being dispensed an angiotensin converting enzyme inhibitor, and 44% started on combination therapy. Overall, 57% of patients were non-persistent after 1 year. Patients’ gender and prescriber qualification showed no association with non-persistence. Younger patients, patients from rural area, patients started with monotherapy, and patients with no medication change had higher odds to become non-persistent. Conclusions The majority of patients were initiated with treatment following hypertension management guidelines, but it is of concern that over half of the patients were non-persistent to antihypertensive therapy in the first year.

Association of income and educational levels with adherence to direct oral anticoagulant therapy in patients with incident atrial fibrillation: A Finnish nationwide cohort study. Pharmacol Res Perspect 2022; 10:e00961. [PMID: 35599338 PMCID: PMC9124817 DOI: 10.1002/prp2.961] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Accepted: 04/17/2022] [Indexed: 11/09/2022] Open
Abstract
Low socioeconomic status has been associated with poor outcomes in patients with atrial fibrillation (AF). However, little is known about socioeconomic disparities in adherence to stroke prevention with direct oral anticoagulants (DOACs). We assessed the hypothesis that AF patients with higher income or educational levels have better adherence to DOACs in terms of treatment implementation and persistence. The used nationwide registry‐based FinACAF cohort covers all patients with incident AF starting DOACs in Finland during 2011–2018. The implementation analyses included 74 222 (mean age 72.7 ± 10.5 years, 50.8% female) patients, and persistence analyses included 67 503 (mean age 75.3 ± 8.9 years, 53.6% female) patients with indication for permanent anticoagulation (CHA2DS2‐VASc score >1 in men and >2 in women). Patients were divided into income quartiles and into three categories based on their educational attainment. Therapy implementation was measured using the medication possession ratio (MPR), and patients with MPR ≥0.90 were defined adherent. Persistence was measured as the incidence of therapy discontinuation, defined as the first 135‐day period without DOAC purchases after drug initiation. Patients with higher income or education were consistently more likely adherent to DOACs in the implementation phase (comparing the highest income or educational category to the lowest: adjusted odds ratios 1.18 (1.12–1.25) and 1.21 (1.15–1.27), respectively). No association with income or educational levels was observed on the incidence of therapy discontinuation. In conclusion, we observed that income and educational levels both have independent positive association on the implementation of DOAC therapy but no association on therapy persistence in patients with AF.
