Prescribing and medical non-adherence after myocardial infarction: qualitative interviews with general practitioners in Germany

Barriers and facilitators of adherence to clinical practice guidelines in Germany-A systematic review

RATIONALE

Clinical Practice Guidelines (CPGs) represent evidence-based tools designed to assist healthcare practitioners and patients in decisions in clinical practice. Evidence supports the clinical benefits of adhering to CPGs. However, their successful implementation and adherence in clinical settings often encounter challenges.

AIMS AND OBJECTIVES

This systematic review aimed to explore barriers and facilitators influencing adherence to CPGs in Germany.

METHOD

The protocol of this study was registered in the Open Science Framework (OSF) registry (DOI: 10.17605/OSF. IO/GMFUB). In November 2022 we searched on PubMed and Embase for primary studies employing qualitative, quantitative and mixed-methods approaches that focus on barriers or facilitators to CPGs adherence in the Germany. Two reviewers independently screened articles, extracted data, and evaluated the quality of the studies. The collected data on barriers and facilitators of CPG adherence were systematically categorized and analyzed using the Theoretical Domains Framework (TDF).

RESULTS

A total of 24 studies were included, mainly focusing on adherence to national CPGs. This review introduces a new domain, guideline characteristics, reflecting the need to address barriers and facilitators to CPG development, implementation, dissemination and format, which couldn't be encompassed within the existing 14 domains of TDF framework. Among healthcare professionals, the most frequently reported influencing factors were related to the environmental context and resources (encompassing aspects such as employer support for CPG utilization), the CPG development and dissemination process (including layout, wording, and interactive tools) and beliefs about consequences (such as contradictions with practical experience). Knowledge (knowledge about the content of CPGs, awareness about published CPGs), primarily as a barrier, and reinforcement facilitators (notably financial support), were also frequently reported.

CONCLUSION

The findings revealed multilevel factors contributing to CPG adherence, with environmental context and resources emerging as the most frequently reported considerations. This systematic review offer holistic insights into the barriers and facilitators of CPG adherence in Germany. The results contribute to a better understanding of the topic and serve as a resource for developing targeted strategies to enhance CPG adherence and implementation within the German healthcare system.

Beta-blockers in post-acute myocardial infarction patients: Drug prescription patterns from 2018 to Italy's first wave of the COVID-19 pandemic

Background: Major guidelines recommend the initiation of a beta-blocker therapy after an acute myocardial infarction (AMI). We aimed to map the treatment pathway of beta-blockers for AMI survivors during the first wave of COVID-19 pandemic in Italy and to investigate predictors for treatment non-initiation. Methods: Healthcare utilization databases of Lombardy Region were investigated. Subjects aged ≥18 years who were hospitalised with AMI in the period February-March-April of 2018, 2019, and 2020 were included, and followed for 30 days from the discharge date, to investigate whether they presented a first prescription of beta-blockers. A multivariate logistic model was performed to evaluate the effect of several covariates on the probability of not receiving a post-AMI beta-blocker therapy. Results: The cohorts comprised 2259, 2383, and 1932 individuals who were hospitalised with AMI in the 3-month period in 2018, 2019, and 2020, respectively. Overall in 2020, about 58-60% of individuals with AMI received a prescription of beta-blockers within 1 month after the discharge. A continuous decreasing trend over time was observed. Men were 30% more likely to start the treatment than women, increasing age was associated with significant increasing probability of not receiving a post-infarction beta-blocker therapy, while having received an antihypertensive or lipid-lowering treatment, or having been hospitalized for heart failure prior to the AMI hospitalization reduced the likelihood of not being treated with beta-blockers. Conclusion: The initiation of beta-blocker treatment after AMI remains an under-prescribed practice, that does not seem to have been further affected by the first wave of the COVID-19 pandemic.

Influence of physician networks on prescribing a new ingredient combination in heart failure: a longitudinal claim data-based study

Background

Since 2016, the combination of sacubitril/valsartan, which combines an angiotensin receptor and neprilysin inhibitor (ARNI), has been recommended in the guidelines for the treatment of heart failure. The adoption of new drugs may be influenced by collaboration and exchange between physicians. We aimed to determine whether characteristics of the professional networks of prescribing physicians were associated with the prescribing of ARNI in Germany.

Methods

We conducted a longitudinal analysis based on claims data in 2016–2018 in Germany. The characteristics of ambulatory care physicians’ networks were determined in the analysis of the patient-sharing networks of physicians in 2017. Binary logistic regression analysis with the outcome ‘prescribes ARNI in 2018’ (present or absent) was carried out, using network characteristics as predictors, adjusted for specialty and sociodemographic characteristics of physicians.

Results

The network analysis included 8370 physicians, who had 144,636 connections. Prescribers had more connections to other physicians compared to non-prescribers (median 31 vs. 23). Regression analysis showed that the numbers of linkages to prescribers of ARNI were positively associated with prescribing ARNI. For 6–10 connections, the average marginal effect (AME) was 0.04 (confidence interval [CI] 95% 0.01–0.06) and for > 10 links the AME 0.07 (CI 95% 0.05–0.10) compared to 0–5 connections to prescriber.

Conclusion

Physicians who shared patients with many other physicians were more likely to prescribe ARNI, independent of physicians’ specialty. This suggested that collaboration and exchange on the basis of patient-sharing with other physicians influenced their medication prescribing decisions.
