Adherence rates and risk factors for suboptimal adherence to secondary prophylaxis for rheumatic fever

Barriers and facilitators of benzathine penicillin G adherence among rheumatic heart disease patients: a mixed methods systematic review using the COM-B (capability, opportunity, and motivation for behavior) model

BACKGROUND

Benzathine penicillin G (BPG) is a proven preventive agent for preventing the progression of rheumatic heart disease (RHD) and is recognized as a standard of care. However, ensuring adherence to BPG remains a global challenge. The objective of this review was to synthesize the available evidence on the barriers to and facilitators of BPG adherence among RHD patients.

METHODS

This systematic review included both qualitative and quantitative studies on RHD patients published in the English language. This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The search strategy involved PubMed, Embase, CINAHL, Global Health, Scopus, and Web of Sciences databases to identify keywords and terms contained in the title and abstract and the index terms used to describe articles. The review included papers published from January 1, 2000, to March 30, 2024. Two independent reviewers screened, appraised, and extracted the data. The data analysis was carried out deductively to fit onto the components of the COM-B (Capability, Opportunity, Motivation-Behaviour) model.

RESULTS

In this review, 1067 records were screened, and 22 studies with 7338 participants were included. Thirty-five barriers and twenty facilitators were identified and mapped onto COM-B components. Physical capability (e.g., felt healthy), psychological capability (e.g., lack of knowledge), reflective motivation (e.g., poor patient handling), automatic motivation (e.g., BPG injection pain), physical opportunity (e.g., BPG unavailability) and social opportunity (e.g., inadequate counseling) were identified as barriers. The most discussed barrier was automatic motivation, followed by psychological capability and physical opportunity.

CONCLUSIONS

Our review revealed variable levels of BPG adherence across studies and identified significant barriers and facilitators. Further research is recommended to identify contextual interventions to address barriers and capitalize on facilitators.

An 8-year single-centre experience of patients with subclinical rheumatic carditis

OBJECTIVE

Transthoracic echocardiography is the gold standard method for screening and confirmation of acute rheumatic fever and subclinical rheumatic heart disease. Secondary antibiotic prophylaxis that is regularly employed in subclinical rheumatic heart disease may help to reverse mild rheumatic carditis lesions, delay the progression of the disease, reduce morbidity and mortality, and improve patients' quality of life.

MATERIALS AND METHODS

We retrospectively evaluated the outcomes of 180 patients with subclinical rheumatic heart disease who were followed up for a mean of 4.92 ± 2.0 (3.5-6.5) years.

RESULTS

Between 1 March 2015 and 31 December 2023, 180 patients diagnosed with subclinical rheumatic heart disease with a mean follow-up of 4.92 ± 2.0 (3.5-6.5) years were included in the study. Of the patients, 50.6% were male, 49.4% were female, mean age at diagnosis was 11.74 ± 3.18 (9.68-13.65) years, and mean follow-up period was 4.92 ± 2.0 (3.5-6.5) years. Further, 87.2 % of the patients had mitral valve regurgitation, 38.3% had aortic valve regurgitation, and 27.2% had both valve (aortic and mitral valve) regurgitation. Moreover, Sydenham chorea was also diagnosed in 7.8% the patients. Of the patients, 90% had mild rheumatic heart disease, 7.8% had moderate rheumatic heart disease, and 2.2% had severe rheumatic heart disease. After the diagnosis of rheumatic heart disease, 76.7% patients received regular and 23.3% irregular secondary benzathine penicillin G prophylaxis.

CONCLUSION

We believe that echocardiography demonstrates its efficacy and safety profile in reducing the risk of rheumatic heart disease in patients diagnosed with subclinical rheumatic carditis and complying with regular secondary antibiotic prophylaxis.

Adherence to secondary antibiotic prophylaxis among patients with acute rheumatic fever and/or rheumatic heart disease: a systematic review and meta-analysis

OBJECTIVES

Worldwide, a number of studies have been conducted to assess the prevalence of adherence to secondary antibiotic prophylaxis and to identify the associated factors (reasons) for poor adherence among patients with rheumatic heart disease or acute rheumatic fever (RHD/ARF). However, results were highly inconsistent with a prevalence ranging from 10% to 93%; and the reported reasons or associated factors have not been systematically reviewed. Therefore, this study aimed to assess the prevalence of adherence to secondary antibiotic prophylaxis among patients with RHD/ARF; and to review the associated factors (reasons) for poor adherence.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

PubMed/Medline, Google Scholar, Cochrane Review and African Journals Online databases.

ELIGIBILITY CRITERIA

Articles published in English from 1 January 2005 to 1 December 2022 and reported the prevalence of adherence using ≥80% cut-off points were included.

DATA EXTRACTION AND SYNTHESIS

Data were extracted using the Microsoft Excel and analysed by STATA V.11.0. A meta-analysis was conducted using the weighted inverse-variance random-effects model. Reasons for poor adherence were identified through thematic analysis.

RESULTS

33 articles with a total sample size of 7158 patients were included. The pooled prevalence of adherence to secondary antibiotic prophylaxis among patients with RHD/ARF was found to be 58.5% (95% CI: 48.2% to 68.7%; I2=99.2%; p<0.001). Rural residency, lack of money, distance from the health institutions, inaccessibility, poor counselling, forgetting schedules, lack of disease knowledge and fear of injection pain were the reported factors or reasons for poor adherence.

CONCLUSION

About 41.5% of patients with RHD/ARF were found to have poor adherence. Long distance from health institutions, forgetting schedules, poor counselling and lack of knowledge and skill among healthcare workers were some of the modifiable reasons for poor adherence. Therefore, decentralisation of the follow-up care, creating schedule reminding systems and providing targeted health education might help to improve adherence.

Secondary prophylaxis and specialist review compliance in paediatric patients with acute rheumatic fever and rheumatic heart disease in a Western Australian metropolitan setting

AIM

Rheumatic heart disease (RHD), a consequence of acute rheumatic fever (ARF), continues to cause significant morbidity and mortality in susceptible young people. Secondary antibiotic prophylaxis is an effective strategy to prevent ARF recurrence and RHD progression. However, the proportion of patients receiving the recommended minimum benzathine penicillin injections (>80%) remains low. This retrospective cohort study reviews the utility of the Hospital in the Home nursing service in providing secondary prophylaxis for outpatients in a metropolitan state capital.

METHODS

Fifty-eight patients with ARF/RHD receiving secondary prophylaxis through the Hospital in the Home service between 1 July 2012 and 30 June 2020 were included. Compliance of secondary prophylaxis, specialist review and echocardiogram frequency were compared against the recommendations from the Australian RHD guidelines.

RESULTS

Forty-six (79%) patients received >80% of recommended doses, with 36% (n = 21) receiving 100% and a further 29% (n = 17) achieving compliance of 90%-99%. We found that 35% of patients attended all specialist reviews (including echocardiography) at the recommended frequency, with 75% of those not attending all reviews, missing only one or two appointments. Compliance was greater in those with more severe disease. In the 12 (21%) patients who did not meet the >80% target, compliance ranged between 33% and 79% (mean 64.5%) and all had priority 3 disease.

CONCLUSION

Community-based administration of secondary prophylaxis through a registry-based system is an effective strategy of improving compliance within a metropolitan area and should be utilised in a culturally safe and collaborative manner to increase uptake.

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.

Patient preferences for prophylactic regimens requiring regular injections in children and adolescents: a systematic review and thematic analysis

BACKGROUND

At present, limited literature exists exploring patient preferences for prophylactic treatment of acute rheumatic fever (ARF) and rheumatic heart disease (RHD). Given low treatment completion rates to this treatment in Australia, where the burden of disease predominantly affects Aboriginal and Torres Strait Islander people, an improved understanding of factors driving patient preference is required to improve outcomes. Due to limited available literature, this review sought to explore treatment preferences for conditions for which the findings might be generalisable to the ARF/RHD context.

OBJECTIVE

Explore treatment preferences of patients, parents/caregivers and healthcare providers towards regular injection regimens in paediatric and adolescent populations for any chronic condition. Findings will be applied to the development of benzathine penicillin G (BPG) prophylactic regimens that are informed by treatment preferences of patients and their caregivers. This in turn should contribute to optimisation of successful BPG delivery.

METHODS

A systematic review of databases (Medline, Embase and Global Health) was conducted using a search strategy developed with expert librarian input. Studies were selected using a two-stage process: (1) title and abstract screen and (2) full text review. Data were extracted using a reviewer-developed template and appraised using the JBI Critical Appraisal tool. Data were synthesised according to a thematic analytical framework.

RESULTS

1725 papers were identified by the database search, conducted between 12 February 2022 and 8 April 2022, and 25 were included in the review. Line-by-line coding to search for concepts generated 20 descriptive themes. From these, five overarching analytical themes were derived inductively: (1) ease of use, (2) tolerability of injection, (3) impact on daily life, (4) patient/caregiver agency and (5) home/healthcare interface.

CONCLUSIONS

The findings of this review may be used to inform the development of preference-led regular injection regimens for paediatric and adolescent patient cohorts-specifically for BPG administration in ARF/RHD secondary prophylaxis.

Trends in Rheumatic Heart Disease-Related Mortality in the United States from 1999 to 2020

There is a lack of mortality data on rheumatic heart disease (RHD) in the United States (US). In light of this, a retrospective analysis was conducted to investigate the temporal, sex-based, racial, and regional trends in RHD-related mortality in the US, ranging from 1999 to 2020. The Center for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC-WONDER) dataset was analyzed, where crude and age-adjusted mortality rates (AAMR) were identified, along with annual percentage changes (APCs) determined by Joinpoint regression. Through the period of 1999 to 2020, there were 141,137 RHD-related deaths reported, with a marginal decline from 4.05/100,000 in 1999 to 3.12/100,000 in 2020. However, the recent rise in AAMR from 2017 to 2020 has created a source of concern (APC: 6.62 [95% CI, 3.19-8.72]). Similar trends were observed in the Black or African American race from 2017 to 2020 (APC: 10.58 [95% CI, 6.29-17.80]). Moreover, the highest percentage change from 2018 to 2020 was observed in residents of large metropolitan areas (APC: 7.6 [95% CI, 2.8-10.5]). A prominent disparity was observed among states, with values ranging from 1.74/100,000 in Louisiana to 5.27/100,000 in Vermont. States within the top 90th percentile of RHD-related deaths included Alaska, Minnesota, Washington, Wyoming, and Vermont. In conclusion, it is imperative to delve deeper into the evidently rising trends of RHD-related mortality and outline the possible sources of social determinants within US healthcare in order to provide equal and quality medical care throughout the nation.

Treatment adherence and its determinants among the rheumatic fever/rheumatic heart disease patients during COVID 19 pandemic - A cross sectional study from Chandigarh, India

Background

Rheumatic heart disease/Rheumatic fever is a non - communicable disease being a major neglected health problem. Recurrent attacks of rheumatic fever can have catastrophic outcomes, therefore regular administration of antibiotics is recommended. During COVID 19 pandemic, people were afraid to approach hospitals hence the compliance and follow up of patients were affected. This study had planned to assess the treatment adherence of patients diagnosed with rheumatic fever/rheumatic heart disease during COVID 19 pandemic and to describe the socio demographic factors, clinical characteristics. This study also determines the factors associated with the treatment adherence.

Methods

A cross sectional study was conducted among Rheumatic Fever/Rheumatic Heart Disease patients, attending Outpatient department at tertiary care hospital during COVID 19 pandemic. Mean score with confidence interval was calculated for quantitative data. P value less than 0.05 is significant.

Results

The Mean (SD) age of the study participants was 41 ± 14.17 years. Treatment adherence was found to be 94.5 percent among Rheumatic Fever/Rheumatic Heart Disease patients during COVID 19 pandemic. 89.5% of injection benzathine penicillin users had an adherence rate above 80 percent. It was found that the presence of comorbidities (Diabetes/Hypertension/both Diabetes and Hypertension) had a statistically significant association with treatment adherence.

Conclusions

Rheumatic Heart Disease is a disease of young and middle -age population affecting predominantly females. The overall adherence rate among Rheumatic Fever/Rheumatic Heart Disease patients was high. High time to maintain hospital-based registry to have follow up of patients.

Secondary Prophylaxis Among First Nations People With Acute Rheumatic Fever in Australia: An Integrative Review

INTRODUCTION

The prevalence of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) among Australia's First Nations populations are some of the highest in the world, accounting for 95% of the 2,244 ARF notifications between 2015 and 2019 in Australia. A key issue in treating ARF is long-term secondary prophylaxis, yet only one in five patients received treatment in 2019. This review identifies barriers to secondary prophylaxis of ARF in Australia's First Nations people.

METHODS

An integrative review was undertaken utilizing PubMed, CINAHL, ProQuest, and Wiley Online. Joanna Briggs Institute critical appraisal tools were used, followed by thematic analysis.

RESULTS

The key themes uncovered included: issues with database and recall systems, patient/family characteristics, service delivery location and site, pain of injection, education (including language barriers), and patient-clinician relationship.

CONCLUSIONS

A national RHD register, change in operation model, improved pain management, improved education, and need for consistent personnel is suggested.

The rise and fall of acute rheumatic fever and rheumatic heart disease: a mini review

Introduction

The incidences of acute rheumatic fever (ARF) and rheumatic heart disease (RHD), which were leading causes of death in children in the 1920s, have decreased substantially. Considering the recent resurgence of scarlet fever and increased incidence of streptococcal pharyngitis in children, an investigation of the current status of ARF and RHD may be worthwhile.

Objective

To summarize the prevalence trends, pathogenic factors, and prevention strategies for ARF and RHD in children.

Methods

A selective search of literature published between January 1920 and February 2023 was done in PubMed, using the terms "acute rheumatic fever", "rheumatic heart disease", "group A Streptococcus", "pharyngitis", "pharyngeal tonsillitis", "scarlet fever", "impetigo", "obstructive sleep apnea syndrome" and "child".

Results

Overcrowded homes and inadequate sanitation led to recurrent group A streptococcal infection, and the causal relationship between group A streptococcal infection and ARF/RHD was well established. Streptococcal infectious diseases, such as group A streptococcal pharyngeal tonsillitis, SF, impetigo, and obstructive sleep apnea syndrome, were associated with the occurrence of ARF and RHD. ARF and RHD were still prevalent in young people of developing countries and economically poor populations of high-income countries. Universal disease registration systems were critical to locating disease outbreaks, tracking disease transmission, and identifying high-risk populations. Four-level prevention strategies were effective in reducing the incidence and mortality of ARF and RHD.

Conclusions

Registry and preventive measures for ARF and RHD should be strengthened in areas of dense population; poor sanitation; resurgence of SF; and high incidence of streptococcal pharyngitis, impetigo, and obstructive sleep apnea syndrome.

Best management of patients with an acute sore throat – a critical analysis of current evidence and a consensus of experts from different countries and traditions

BACKGROUND

There is a very large body of publications discussing the management of patients with an acute sore throat. Advocates for a restrictive antibiotic policy and advocates for a more liberal use of antibiotics emphasise different and valid arguments and to date have not been able to unite in a consensus. Contradicting guidelines based on the same body of knowledge is not logical, may cause confusion and cause unwanted variation in clinical management.

METHODS

In multiple video meetings and email correspondence from March to November 2022 and finally in a workshop at the annual meeting for the North American Primary Care Group in November 2022, experts from different countries representing different traditions agreed on how the current evidence should be interpreted.

RESULTS

This critical analysis identifies that the problem can be resolved by introducing a new triage scheme considering both the acute risk for suppurative complications and sepsis as well as the long-term risk of developing rheumatic fever.

CONCLUSIONS

The new triage scheme may solve the long-standing problem of advocating for a restrictive use of antibiotics while also satisfying concerns that critically ill patients might be missed with severe consequences. We acknowledge that the perspective of this problem is vastly different between high- and low-income countries. Furthermore, we discuss the new trend which allows nurses and pharmacists to independently manage these patients and the increased need for safety netting required for such management.

Adherence to secondary prevention of rheumatic fever and rheumatic heart disease in young people: an 11-year retrospective study

OBJECTIVES

To evaluate the secondary prevention of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) in the Townsville region, Australia.

METHODS

Adherence to benzathine benzylpenicillin G (BPG) was determined for 196 children and young adults aged under 22 years between January 2009 and December 2019, and factors associated with BPG adherence were analysed. Secondary outcomes included attendance at specialist reviews and echocardiograms.

RESULTS

Adequate adherence (80%) to regular BPG injections was met by 51.1% of the cohort. Adequate BPG adherence more likely occurred for those that attended the Paediatric Outreach Clinic (OR4.15, 95%CI:2.13-8.05) or a school delivery program (OR1.87, 95%CI:1.11-3.45). People with moderate/severe RHD had greater BPG adherence (OR1.76,95%CI:1.00-3.10). People in rural/remote areas were less likely to have adequate BPG adherence compared to urban counterparts (OR0.31, 95%CI:0.15-0.65). Adherence to echocardiography was 66% and specialist review attendance was 12.5-50%.

CONCLUSION

Half of the cohort in the Townsville region received adequate BPG prophylaxis to prevent ARF/RHD. Although rates were relatively higher than those reported in other Australian regions, health delivery goals should be close to 100%. Low attendance at specialist services was reported. Implication for public health: Delivery models with dedicated services, case management and family support could improve BPG adherence in individuals with ARF/RHD. Further resources in rural and remote areas are needed.
