Health systems in the Republic of Congo: challenges and opportunities for implementing tuberculosis and HIV collaborative service, research, and training activities

Further analysis of tuberculosis in eight high-burden countries based on the Global Burden of Disease Study 2021 data

BACKGROUNDS

Most significant findings from the Global Tuberculosis (TB) Report 2023 indicate that India, Indonesia, China, the Philippines, Pakistan, Nigeria, Bangladesh, and the Democratic Republic of the Congo (DRC) collectively contribute to approximately two-thirds of global TB cases. This study aims to provide crucial data-driven insights and references to improve TB control measures through a comprehensive analysis of these eight high-burden countries.

METHODS

The eight high-burden TB countries analyzed in this study include India, Indonesia, China, the Philippines, Pakistan, Nigeria, Bangladesh, and the DRC. Age-standardized incidence rates (ASIR) of TB were derived from the Global Burden of Diseases Study 2021 data. Temporal trends were analyzed using Joinpoint regression. An age-period-cohort model was applied to examine the risk ratios (RR) of TB across diverse age groups, periods, and birth cohorts. A Bayesian age-period-cohort framework was employed to predict the ASIR of TB by 2030.

RESULTS

The study found that the Philippines (average annual percentage change = 3.1%, P < 0.001) exhibited an upward trend from 1990 to 2021. In India, the Philippines, Pakistan, and Bangladesh, the RR of TB incidence exceeded 1 after individuals reached 25 years old. Notably, the RR has shown a consistent upward trend since 2001, peaking during the period of 2017-2021 with an estimated RR of 1.5 (P < 0.001) in the Philippines. Similarly, the highest RR was observed during the period of 2017-2021 reaching 1.1 (P < 0.001) in the DRC. In the Philippines, the markedly increasing RR values for TB have been observed among individuals born after 1997-2001. Projections suggest that the ASIR of TB is expected to follow a continued upward trajectory, with an estimated rate of 392.9 per 100,000 by 2030 in the Philippines; India and Indonesia are projected to achieve less than 20.0% of the target set by the World Health Organization (WHO).

CONCLUSIONS

Among the eight high-burden countries, the Philippines, India and Indonesia are diverging from the goals set by the WHO, and the risk of TB in the Philippines and the DRC shows a trend toward affecting younger populations, which suggests that the management strategies for TB patients need to be further strengthened.

Prognostic factors of time to first abortion after sexual debut among fragile state Congolese women: a survival analysis

BACKGROUND

Despite the common restrictive abortion laws, abortion remains widespread in sub-Saharan Africa (SSA) countries. Women still utilize abortion services and put their lives and health at risk because abortion can only be procured illegally in private facilities such as mid-level or small patent medicine store that may be manned by unskilled providers or through a non-medicated approach. The objective of this study was to investigate the prevalence of abortion, the reasons women had abortions, median years to first abortion after sexual debut and examine the factors of time to first abortion among women of reproductive age in the Republic of Congo.

METHODS

We used data from the most recent Republic of Congo Demographic and Health Survey (DHS). A total sample of 3622 women aged 15-49 years was analyzed. We estimated the overall prevalence of abortion and median years to first abortion. Furthermore, we examined the factors of time to first abortion after sexual debut using multivariable Cox regression and reported the estimates using adjusted Hazard Ratio (aHR) and 95% confidence intervals (CI). Statistical significance was determined at p < 0.05.

RESULTS

The prevalence of abortion was 60.0% and median years of time to first abortion after sexual debut was 9.0. The prominent reasons for abortion were due to too short birth interval (23.8%), lack of money (21.0%) and that husband/partner did not need a child at that time (14.0%). Women's age and region were notable factors in timing to first abortion. Furthermore, women from poorer, middle, richer and richest households had 34, 67, 86 and 94% higher risk of abortion respectively, when compared with women from poorest households (all p < 0.05). Women currently in union/living with a man and formerly in union had 41 and 29% reduction in the risk of abortion respectively, when compared with those never in union (all p < 0.05). In addition, women with primary and secondary+ education had 42 and 76% higher risk of abortion respectively, when compared with women with no formal education (all p < 0.05).

CONCLUSION

There was high prevalence of abortion with short years at first abortion. Abortion was associated with women's characteristics. There is need for unwanted pregnancy prevention intervention and the improvement in pregnancy care to reduce adverse pregnancy outcomes among women.

Pharmacogenetic considerations in the treatment of co-infections with HIV/AIDS, tuberculosis and malaria in Congolese populations of Central Africa

BACKGROUND

HIV-infection, tuberculosis and malaria are the big three communicable diseases that plague sub-Saharan Africa. If these diseases occur as co-morbidities they require polypharmacy, which may lead to severe drug-drug-gene interactions and variation in adverse drug reactions, but also in treatment outcomes. Polymorphisms in genes encoding drug-metabolizing enzymes are the major cause of these variations, but such polymorphisms may support the prediction of drug efficacy and toxicity. There is little information on allele frequencies of pharmacogenetic variants of enzymes involved in the metabolism of drugs used to treat HIV-infection, TB and malaria in the Republic of Congo (ROC). The aim of this study was therefore to investigate the occurrence and allele frequencies of 32 pharmacogenetic variants localized in absorption distribution, metabolism and excretion (ADME) and non-ADME genes and to compare the frequencies with population data of Africans and non-Africans derived from the 1000 Genomes Project.

RESULTS

We found significant differences in the allele frequencies of many of the variants when comparing the findings from ROC with those of non-African populations. On the other hand, only a few variants showed significant differences in their allele frequencies when comparing ROC with other African populations. In addition, considerable differences in the allele frequencies of the pharmacogenetic variants among the African populations were observed.

CONCLUSIONS

The findings contribute to the understanding of pharmacogenetic variants involved in the metabolism of drugs used to treat HIV-infection, TB and malaria in ROC and their diversity in different populations. Such knowledge helps to predict drug efficacy, toxicity and ADRs and to inform individual and population-based decisions.

Through service providers' eyes: health systems factors affecting implementation of tuberculosis control in Enugu State, South-Eastern Nigeria

Background

Well-functioning health systems are essential to achieving global and national tuberculosis (TB) control targets. This study examined health system factors affecting implementation of TB control programme from the perspectives of service providers.

Methods

The study was conducted in Enugu State, South-eastern Nigeria using qualitative, cross-sectional design involving 23 TB service providers (13 district TB supervisors and 10 facility TB focal persons). Data were collected through in-depth, semi-structured interviews using a health system dynamic framework and analysed thematically.

Results

Stewardship from National TB Control Programme (NTP) improved governance of TB control, but stewardship from local government was weak. Government spending on TB control was inadequate, whereas donors fund TB control. Poor human resources management practices hindered TB service delivery. TB service providers have poor capacity for data management because changes in recording and reporting tools were not matched with training of service providers. Drugs and other supplies to TB treatment centres were interrupted despite the use of a logistics agency. Poor integration of TB into general health services, weak laboratory capacity, withdrawal of subsidies to community volunteers and patent medicine vendors, poorly funded patient tracking systems, and ineffectual TB/HIV collaboration resulted in weak organisation of TB service delivery.

Conclusion

Health systems strengthening for TB control service must focus on effective oversight from NTP and local health system; predictable domestic resource mobilisation through budgets and social health insurance; training and incentives to attract and retain TB service providers; effective supply and TB drug management; and improvements in organization of service delivery.

Strengthening nutrition services within integrated community case management (iCCM) of childhood illnesses in the Democratic Republic of Congo: Evidence to guide implementation

In the Democratic Republic of Congo, 43% of children under 5 years of age suffer from stunting, and the majority (60%) of children, 6–59 months of age, are anaemic. Malaria, acute respiratory infections, and diarrheal diseases are common among children less than 5 years of age, with 31% of children 6–59 months affected by malaria. This qualitative implementation science study aimed to identify gaps and opportunities available to strengthen service delivery of nutrition within integrated community case management (iCCM) at the health facility and community level in Tshopo Province, Democratic Republic of Congo, through the following objectives: (a) examine cultural beliefs and perceptions of infant and young child feeding (IYCF) and child illness, (b) explore the perspectives and knowledge of facility‐based and community‐based health providers on nutrition and iCCM, and (c) gain an understanding of the influence of key family and community members on IYCF and care‐seeking practices. This study involved in‐depth interviews with mothers of children under 5 years of age (n = 48), grandmothers (n = 20), fathers (n = 21), facility‐based providers (n = 18), and traditional healers (n = 20) and eight focus group discussions with community health workers. Study findings reveal most mothers reported diminished quantity and quality of breastmilk linked to child/maternal illness, inadequate maternal diet, and feedings spaced too far apart. Mothers' return to work in the field led to early introduction of foods prior to 6 months of age, impeding exclusive breastfeeding. Moreover, children's diets are largely limited in frequency and diversity with small quantities of foods fed. Most families seek modern and traditional medicine to remedy child illness, dependent on type of disease, its severity, and cost. Traditional healers are the preferred source of information for families on certain child illnesses and breastmilk insufficiency. Community health workers often refer and accompany families to the health centre, yet are underutilized for nutrition counselling, which is infrequently given. Programme recommendations are to strengthen health provider capacity to counsel on IYCF and iCCM while equipping health workers with updated social and behavior change communication (SBCC) materials and continued supportive supervision. In addition, targeting key influencers to encourage optimal IYCF practices is needed through community and mother support groups. Finally, exploring innovative ways to work with traditional healers, to facilitate referrals for sick/malnourished children and provide simple nutrition advice for certain practices (i.e., breastfeeding), would aid in strengthening nutrition within iCCM.

QUALITY AND MANAGEMENT OF CARE TO TUBERCULOSIS/HIV COINFECTION IN THE STATE OF SÃO PAULO, BRAZIL

ABSTRACT Objective: to analyze the quality and management of care to tuberculosis/HIV coinfection in the state of São Paulo, Brazil. Methods: a descriptive study involving municipalities having at least five cases of tuberculosis/HIV coinfection in the Brazilian state of São Paulo notified in the tuberculosis notification system. To analyze the quality and management of care to tuberculosis/HIV coinfection, indicators were designed, based on tuberculosis evaluability assessment studies, and validated in Brazil. The municipalities were grouped according to their care quality and then submitted to multiple correspondence analysis. Results: the study formed a group with 18 municipalities (42.86%) with satisfactory care and management quality, and another group with 24 municipalities (57.14%) with a quality characterized as unsatisfactory. In the municipalities that showed a satisfactory result, the investigation identified a low proportion of tuberculosis/HIV coinfection, a low AIDS incidence rate, intermediate population size, and high coverage of the Community Health Workers’ Program and Family Health Strategy. The municipalities with unsatisfactory quality had a high proportion of tuberculosis/HIV coinfection and a high AIDS incidence rate. Conclusion: the study reveals the defining characteristics of quality and management of care to tuberculosis/HIV coinfection as chronic conditions, bringing relevant elements regarding the mobilization of resources and investments in the municipalities where these are necessary. Additionally, the investigation shows that health results are critical where care quality is unsatisfactory, pointing out the need for reorganizing care and the management of actions involving control of tuberculosis/HIV coinfection in these contexts.

Achieving sustainable development goals for HIV/AIDS in the Republic of the Congo - Progress, obstacles and challenges in HIV/AIDS health services

The HIV epidemic continues to be a major global public health issue. Since 2012, there has been a paucity of information from the Republic of the Congo on HIV incidence and prevalence rates, national HIV programme effectiveness, highly active antiretroviral therapy (HAART) rollout, patient adherence to treatment, operational and basic science research studies on HIV/AIDS, and donor funding and its impact on the country. A review of the existing literature on HIV in the Republic of the Congo was conducted, focused on prevalence trends, effectiveness of the current national HIV programme, HAART rollout, patient adherence to antiretrovirals (ARVs), resistance to ARVs, the cost of treatment, and operational issues affecting HIV/AIDS programmes in the country. In light of the findings, several important priority areas for scaling-up HIV/AIDS services, programmatic and research activities in the Republic of the Congo are highlighted.

Collaborative Approaches and Policy Opportunities for Accelerated Progress toward Effective Disease Prevention, Care, and Control: Using the Case of Poverty Diseases to Explore Universal Access to Affordable Health Care

Background

There is a massive global momentum to progress toward the sustainable development and universal health coverage goals. However, effective policies to health-care coverage can only emerge through high-quality services delivered to empowered care users by means of strong local health systems and a translational standpoint. Health policies aimed at removing user fees for a defined health-care package may fail at reaching desired results if not applied with system thinking.

Method

Secondary data analysis of two country-based cost-of-illness studies was performed to gain knowledge in informed decision-making toward enhanced access to care in the context of resource-constraint settings. A scoping review was performed to map relevant experiences and evidence underpinning the defined research area, the economic burden of illness.

Findings

Original studies reflected on catastrophic costs to patients because of care services use and related policy gaps. Poverty diseases such as tuberculosis (TB) may constitute prime examples to assess the extent of effective high-priority health-care coverage. Our findings suggest that a share of the economic burden of illness can be attributed to implementation failures of health programs and supply-side features, which may highly impair attainment of the global stated goals. We attempted to define and discuss a knowledge development framework for effective policy-making and foster system levers for integrated care.

Discussion

Bottlenecks to effective policy persist and rely on interrelated patterns of health-care coverage. Health system performance and policy responsiveness have to do with collaborative work among all health stakeholders. Public–private mix strategies may play a role in lowering the economic burden of disease and solving some policy gaps. We reviewed possible added value and pitfalls of collaborative approaches to enhance dynamic local knowledge development and realize integration with the various health-care silos.

Conclusion

Despite a large political commitment and mobilization efforts from funding, the global development goal of financial protection for health—newly adopted in TB control as no TB-affected household experiencing catastrophic expenditure—may remain aspirational. To enhance effective access to care for all, innovative opportunities in patient-centered and collaborative practices must be taken. Further research is greatly needed to optimize the use of locally relevant knowledge, networks, and technologies.
