Economic analysis of a health system strengthening program in the Democratic Republic of the Congo

INTRODUCTION

Due to the Democratic Republic of the Congo’s (DRC) precarious health system that provides only limited access to health care, the European Union, via Memisa Belgium, implemented a program to strengthen provision of and access to health care (known as PRO DS) in the provinces of Kongo Central and Ituri. This program took a holistic approach, seeking to improve equitable access and combat malnutrition.

METHODS

To measure the program’s social return on investment and to estimate the cost per capita and effectiveness per euro invested (efficiency), a 61-month (1 July 2017 to 31 July 2022) cost-effectiveness evaluation with a societal perspective was carried out. The double-difference method was used to compare the results of PRO DS and non-PRO DS zones. The social return on investment was assessed via the ratio of effectiveness to costs.

RESULTS

Analyses revealed the program cost between 3.72 and 3.96 euros per capita per year (2022) in Kongo Central, and between 3.12 and 3.36 euros in Ituri. Importantly, it was cost-effective in the areas of reproductive health, nutrition, and the use of health and nutrition services.

CONCLUSIONS

The program’s strong nutritional component and overall holistic vision may explain why it was so efficient. PRO DS stands out from other programs that focus solely on one specific problem or population. Although the program has some limitations, it would be worthwhile for the government to invest in it.

Shako Djunga, M.D., 1938 -1986: The first Congolese Neurosurgeon

Antoine Shako Hiango Omokanda Djunga was the pioneer of neurosurgery in the Democratic Republic of Congo (DRC), a country located in Central Africa. He was born in 1938 in Sankuru, a province of the DRC. He graduated from the Free University of Brussels medical school and later trained there in neurosurgery. Thereafter, he completed a fellowship at Bellevue Hospital in New York. As a neurosurgeon, he worked at the Kinshasa University Clinic (KUC) of Lovanium School of Medicine in the DRC, where he introduced neurosurgery and advocated for the construction of the first dedicated neurosurgical operating room. His leadership helped ensure sustainability in the field in the DRC. He died at the age of 48 leaving a void in neurosurgery and an unfulfilled mission of advocating for the construction of an independent neurosurgery hospital in the DRC.

Meningitis during COVID -19 pandemic in the Democratic Republic of Congo: A call for concern

Meningitis is a severe infection and a major public health challenge. The meningitis outbreak which had resurfaced amid the coronavirus disease 2019 (COVID-19) pandemic in the Democratic Republic of Congo (DRC) has been further stressing the health care systems that are already overburdened with detecting, preventing, and treating the current coronavirus disease. The recent meningitis outbreak in the DRC has resulted in a high case fatality ratio of 50% - an extremely worrying concern. Robust strategies are hence needed to curb the spread of the disease amid the COVID-19 pandemic, to prevent further adverse health outcomes and to mitigate the compounding burden on the country's healthcare systems. Several measures such as vaccination campaigns, adherence to sanitation and hygiene, improved surveillance and diagnostic capabilities could help prevent future epidemics in the country.

Detection and genetic characterization of African swine fever virus (ASFV) in clinically infected pigs in two districts in South Kivu province, Democratic Republic Congo

African swine fever (ASF) is a notifiable contagious disease caused by the African swine fever virus (ASFV), leading to a serious socio-economic impact, constraining pig industry, and affecting food security worldwide. This study aimed to detect and characterize ASFV strains from suspected infected domestic pigs in two South-Kivu province districts of the Democratic Republic of the Congo (DRC). A total of 155 pig samples were screened for viral DNA and sequencing at multiple loci. An infection rate of 5.2% (8/155) was recorded from a total of 155 blood samples with the highest ASFV infection rate of 8% for Uvira (6/75) and mostly in female pigs 5 (7.6%). Most ASF associated clinical signs were redness on the skin and snout at 49% (95% CI: 21–34), followed by the unwillingness of pigs to stand at 29 % (95%, CI: 19–35). Phylogenetic analysis of partial B646L (p72) and the full-length E183 (p54) gene sequences revealed the circulation of genotypes IX and X, which clustered with previously reported viruses in the same region, Uganda, Kenya, and Tanzania. Intragenotypic resolution of the CVR region clustered the viruses into two subgroups: the genotype X strain subgroup (10 repeats, AAAABNAABA) and the genotype IX strain subgroup (11 repeats, AAAAAAAAAAF). This finding provides additional evidence that genetically similar ASFV strains may be circulating within South Kivu province and highlights the need for improved coordination to prevent the spread of the disease in non-infected areas.

A miner with No left lung: Extensive pulmonary destruction in delayed effective Multi-Drug-Resistant Tuberculosis treatment

We report a case of extensive pulmonary destruction due to delayed effective pulmonary tuberculosis (TB) treatment in an adult artisanal miner in eastern Democratic Republic of Congo. Xpert MTB/RIF was positive after his second rifampicin-susceptible TB treatment. Chest X-rays were suggestive of large cavity, fibrosis of remaining lung and air-fluid levels at the base of the destroyed lung. The patient passed away after delayed effective TB regimens. Clinicians should be aware that urgent surgical intervention is often required to prevent lethal acute respiratory failure and shock notwithstanding effective chemotherapy in such condition. Effort is needed to timely diagnose multidrug resistance TB and to implement thoracic surgery for TB in high burden countries.

Geospatial and age-related patterns of Taenia solium taeniasis in the rural health zone of Kimpese, Democratic Republic of Congo

•

We assessed patterns of taeniasis in 24 village communities of Kimpese health zone.

•

Prevalence of taeniasis was very high and varied between households and villages.

•

Children of five to ten years were the most infected age group.

•

Taeniasis was not spatially correlated with porcine cysticercosis.

Background

Taenia solium infections are mostly endemic in less developed countries where poor hygiene conditions and free-range pig management favor their transmission. Knowledge on patterns of infections in both human and pig is crucial to design effective control strategies. The aim of this study was to assess the prevalence, risk factors and spatial distribution of taeniasis in a rural area of the Democratic Republic of Congo (DRC), in the prospect of upcoming control activities.

Methods

A cross-sectional study was conducted in 24 villages of the health zone of Kimpese, Bas Congo Province. Individual and household characteristics, including geographical coordinates were recorded. Stool samples were collected from willing participants and analyzed using the copro-antigen enzyme-linked immunosorbent assay (copro-Ag ELISA) for the detection of taeniasis. Blood samples were collected from pigs and analyzed using the B158/B60 monoclonal antibody-based antigen ELISA (sero-Ag ELISA) to detect porcine cysticercosis. Logistic regression and multilevel analysis were applied to identify risk factors. Global clustering and spatial correlation of taeniasis and porcine cysticercosis were assessed using K functions. Local clusters of both infections were identified using the Kulldorff’s scan statistic.

Results

A total of 4751 participants above 5 years of age (median: 23 years; IQR: 11–41) were included. The overall proportion of taeniasis positivity was 23.4% (95% CI: 22.2–24.6), ranging from 1 to 60% between villages, with a significant between-household variance of 2.43 (SE = 0.29, p < 0.05). Taeniasis was significantly associated with age (p < 0.05) and the highest positivity was found in the 5–10 years age group (27.0% (95% CI: 24.4–29.7)). Overall, 45.6% (95% CI: 40.2–51) of sampled pigs were sero-positive. The K functions revealed a significant overall clustering of human and pig infections but no spatial dependence between them. Two significant clusters of taeniasis (p<0.001; n = 276 and n = 9) and one cluster of porcine cysticercosis (p<0.001; n = 24) were found.

Conclusion

This study confirms high endemicity and geographical dispersal of taeniasis in the study area. The role of age in taeniasis patterns and significant spatial clusters of both taeniasis and porcine cysticercosis were evidenced, though no spatial correlation was found between human and pig infections. Urgent control activities are needed for this endemic area.
