Socio-economic determinants influencing adherence to secondary prophylaxis in patients with rheumatic heart disease: a systematic review.

Introduction: Rheumatic heart disease (RHD) poses a substantial global health challenge, especially impacting resource-limited nations, with over 40.5 million cases reported in 2019. The crucial role of Benzathine penicillin G in both primary and secondary prevention, particularly the latter, emphasizes its significance.

Method: Following PRISMA guidelines, our systematic review explored Medline, Scopus, Google Scholar, and Embase databases from 1990 to 2022. Registered with PROSPERO ), the review utilized quality appraisal tools, including the PRISMA checklist, Cochrane bias tool and Newcastle-Ottawa scale. The objective was to identify and stratify the impact of socio-economic factors on adherence to secondary prophylaxis in RHD.

Results And Discussion: The impact of education on adherence has been found to be significant. Socially disadvantaged environments significantly influenced adherence, shaped by education, socio-economic status, and geographical location and access to healthcare. Surprisingly, lower education levels were associated with better adherence in certain cases. Factors contributing to decreased adherence included forgetfulness, injection-related fears, and healthcare provider-related issues. Conversely, higher adherence correlated with younger age, latent disease onset, increased healthcare resources, and easy access.

Conclusion: Patient education and awareness were crucial for improving adherence. Structured frameworks, community initiatives, and outreach healthcare programs were identified as essential in overcoming barriers to secondary prophylaxis. Taking active steps to address obstacles like long-distance commute, waiting time, injection fears, and financial issues has the potential to greatly improve adherence. This, in turn, can lead to a more effective prevention of complications associated with RHD.
