RESUMEN
Introduction: Rheumatic heart disease (RHD) remains a significant public health problem in countries with limited health resources. People living with RHD face numerous social challenges and have difficulty navigating ill-equipped health systems. This study sought to understand the impact of RHD on PLWRHD and their households and families in Uganda. Methods: In this qualitative study, we conducted in-depth interviews with 36 people living with RHD sampled purposively from Uganda's national RHD research registry, stratifying the sample by geography and severity of disease. Our interview guides and data analysis used a combination of inductive and deductive methods, with the latter informed by the socio-ecological model. We ran thematic content analysis to identify codes that were then collapsed into themes. Coding was done independently by three analysts, who compared their results and iteratively updated the codebook. Results: The inductive portion of our analysis, which focused on the patient experience, revealed a significant impact of RHD on work and school. Participants often lived in fear of the future, faced limited childbirth choices, experienced domestic conflict, and suffered stigmatization and low self-esteem. The deductive portion of our analysis focused on barriers and enablers to care. Major barriers included the high out-of-pocket cost of medicines and travel to health facilities, as well as poor access to RHD diagnostics and medications. Major enablers included family and social support, financial support within the community, and good relationships with health workers, though this varied considerably by location. Conclusion: Despite several personal and community factors that support resilience, PLWRHD in Uganda experience a range of negative physical, emotional, and social consequences from their condition. Greater investment is needed in primary healthcare systems to support decentralized, patient-centered care for RHD. Implementing evidence-based interventions that prevent RHD at district level could greatly reduce the scale of human suffering. There is need to increase investment in primary prevention and tackling social determinants, to reduce the incidence of RHD in communities where the condition remains endemic.

Background: Untreated streptococcal pharyngitis is a precursor to rheumatic heart disease (RHD) and remains a significant public health issue in many countries. Understanding local determinants of treatment-seeking behaviors can help tailor RHD prevention programs. Objective: We sought to elicit perceptions of pharyngitis and related healthcare use in a range of communities in Uganda. Methods: We conducted six focus group discussions (FGD) in three districts that were representative of the country's socioeconomic and cultural heterogenetity. Participants were recruited from six villages (two per district), and FGDs were audio recorded, transcribed and translated into English. Deductive and inductive analysis of the transcripts was done via open axial and sequential coding, which informed development of clusters, themes and subthemes. We extracted quotations from the transcripts to illustrate these themes. Results: We identified nine key themes in three major domains: knowledge and perception of pharyngits, treatment practices, and barriers to uptake of formal public-sector healthcare services. Community awareness and understanding of the consequences of pharyngitis were low. Stated barriers to care were usually systemic in nature and included low overall confidence in the healthcare system and substantial costs associated with transportation and medications. Conclusion: The FGDs identified several approaches to shape community perceptions of pharyngitis and improve utilization of interventions to prevent RHD. In Uganda, information-education-communication interventions probably need to be combined with structural interventions that make formal public-sector healthcare more accessible to at-risk populations.

OBJECTIVE: To determine the ability to accurately diagnose acute rheumatic fever (ARF) given the resources available at three levels of the Ugandan healthcare system. METHODS: Using data obtained from a large epidemiological database on ARF conducted in three districts of Uganda, we selected variables that might positively or negatively predict rheumatic fever based on diagnostic capacity at three levels/tiers of the Ugandan healthcare system. Variables were put into three statistical models that were built sequentially. Multiple logistic regression was used to estimate ORs and 95% CI of predictors of ARF. Performance of the models was determined using Akaike information criterion, adjusted R2, concordance C statistic, Brier score and adequacy index. RESULTS: A model with clinical predictor variables available at a lower-level health centre (tier 1) predicted ARF with an optimism corrected area under the curve (AUC) (c-statistic) of 0.69. Adding tests available at the district level (tier 2, ECG, complete blood count and malaria testing) increased the AUC to 0.76. A model that additionally included diagnostic tests available at the national referral hospital (tier 3, echocardiography, anti-streptolysin O titres, erythrocyte sedimentation rate/C-reactive protein) had the best performance with an AUC of 0.91. CONCLUSIONS: Reducing the burden of rheumatic heart disease in low and middle-income countries requires overcoming challenges of ARF diagnosis. Ensuring that possible cases can be evaluated using electrocardiography and relatively simple blood tests will improve diagnostic accuracy somewhat, but access to echocardiography and tests to confirm recent streptococcal infection will have the greatest impact.

Background: Rheumatic heart disease (RHD) has declined dramatically in wealthier countries in the past three decades, but it remains endemic in many lower-resourced regions and can have significant costs to households. The objective of this study was to quantify the economic burden of RHD among Ugandans affected by RHD. Methods: This was a cross-sectional cost-of-illness study that randomly sampled 87 participants and their households from the Uganda National RHD registry between December 2018 and February 2020. Using a standardized survey instrument, we asked participants and household members about outpatient and inpatient RHD costs and financial coping mechanisms incurred over the past 12 months. We used descriptive statistics to analyze levels and distributions of costs and the frequency of coping strategies. Multivariate Poisson regression models were used to assess relationships between socioeconomic characteristics and utilization of financial coping mechanisms. Results: Most participants were young or women, demonstrating a wide variation in socioeconomic status. Outpatient and inpatient costs were primarily driven by transportation, medications, and laboratory tests, with overall RHD direct and indirect costs of $78 per person-year. Between 20 and 35 percent of households experienced catastrophic healthcare expenditure, with participants in the Northern and Western Regions 5-10 times more likely to experience such hardship and utilize financial coping mechanisms than counterparts in the Central Region, a wealthier area. Increases in total RHD costs were positively correlated with increasing use of coping behaviors. Conclusion: Ugandan households affected by RHD, particularly in lower-income areas, incur out-of-pocket costs that are very high relative to income, exacerbating the poverty trap. Universal health coverage policy reforms in Uganda should include mechanisms to reduce or eliminate out-of-pocket expenditures for RHD and other chronic diseases.
RESUMEN
BACKGROUND: In 2018, the World Health Assembly mandated Member States to take action on rheumatic heart disease (RHD), which persists in countries with weak health systems. We conducted an assessment of the current state of RHD-related healthcare in Uganda. METHODOLOGY/PRINCIPAL FINDINGS: This was a mixed-methods, deductive simultaneous design study conducted in four districts of Uganda. Using census sampling, we surveyed health facilities in each district using an RHD survey instrument that was modeled after the WHO SARA tool. We interviewed health workers with experience managing RHD, purposively sampling to ensure a range of qualification and geographic variation. Our final sample included 402 facilities and 36 health workers. We found major gaps in knowledge of clinical guidelines and availability of diagnostic tests. Antibiotics used in RHD prevention were widely available, but cardiovascular medications were scarce. Higher levels of service readiness were found among facilities in the western region (Mbarara district) and private facilities. Level III health centers were the most prepared for delivering secondary prevention. Health worker interviews revealed that limited awareness of RHD at the district level, lack of diagnostic tests and case management registries, and absence of clearly articulated RHD policies and budget prioritization were the main barriers to providing RHD-related healthcare. CONCLUSIONS/SIGNIFICANCE: Uganda's readiness to implement the World Health Assembly RHD Resolution is low. The forthcoming national RHD strategy must focus on decentralizing RHD diagnosis and prevention to the district level, emphasizing specialized training of the primary healthcare workforce and strengthening supply chains of diagnostics and essential medicines.

BACKGROUND: Acute rheumatic fever is infrequently diagnosed in sub-Saharan African countries despite the high prevalence of rheumatic heart disease. We aimed to determine the incidence of acute rheumatic fever in northern and western Uganda. METHODS: For our prospective epidemiological study, we established acute rheumatic fever clinics at two regional hospitals in the north (Lira district) and west (Mbarara district) of Uganda and instituted a comprehensive acute rheumatic fever health messaging campaign. Communities and health-care workers were encouraged to refer children aged 3-17 years, with suspected acute rheumatic fever, for a definitive diagnosis using the Jones Criteria. Children were referred if they presented with any of the following: (1) history of fever within the past 48 h in combination with any joint complaint, (2) suspicion of acute rheumatic carditis, or (3) suspicion of chorea. We excluded children with a confirmed alternative diagnosis. We estimated incidence rates among children aged 5-14 years and characterised clinical features of definite and possible acute rheumatic fever cases. FINDINGS: Data were collected between Jan 17, 2018, and Dec 30, 2018, in Lira district and between June 5, 2019, and Feb 28, 2020, in Mbarara district. Of 1075 children referred for evaluation, 410 (38%) met the inclusion criteria; of these, 90 (22%) had definite acute rheumatic fever, 82 (20·0%) had possible acute rheumatic fever, and 24 (6%) had rheumatic heart disease without evidence of acute rheumatic fever. Additionally, 108 (26%) children had confirmed alternative diagnoses and 106 (26%) had an unknown alternative diagnosis. We estimated the incidence of definite acute rheumatic fever among children aged 5-14 years as 25 cases (95% CI 13·7-30·3) per 100 000 person-years in Lira district (north) and 13 cases (7·1-21·0) per 100 000 person-years in Mbarara district (west). INTERPRETATION: To the best of our knowledge, this is the first population-based study to estimate the incidence of acute rheumatic fever in sub-Saharan Africa. Given the known rheumatic heart disease burden, it is likely that only a proportion of children with acute rheumatic fever were diagnosed. These data dispel the long-held hypothesis that the condition does not exist in sub-Saharan Africa and compel investment in improving prevention, recognition, and diagnosis of acute rheumatic fever.
