Wording the trajectory of the three-year COVID-19 epidemic in a general population - Belgium.

The trajectory of COVID-19 epidemic waves in the general population of Belgium was analysed by defining quantitative criteria for epidemic waves from March 2020 to early 2023. Peaks and starting/ending times characterised nine waves numerated I to IX based on the daily reported incidence number (symbol INCID) and three "endemic" interval periods between the first four waves. The SIR compartmental model was applied to the first epidemic wave by fitting the daily prevalence pool (symbol I) calculated as the sum of the daily incidence rate and estimated number of subjects still infectious from the previous days. The basic reproductive number R0 was calculated based on the exponential growth rate during the early phase and on medical literature knowledge of the time of generation of SARS-CoV-2 infection. The first COVID-19 wave was well fitted by an open SIR model. According to this approach, dampened recurrent epidemic waves evolving through an endemic state would have been expected. This was not the case with the subsequent epidemic waves being characterised by new variants of concern (VOC). Evidence-based observations: 1) each epidemic wave affected less than a fifth of the general population; 2) the Vth epidemic wave (VOC Omicron) presented the greatest amplitude. The lack of recurrence of the same VOC during successive epidemic waves strongly suggests that a VOC has a limited persistence, disappearing from the population well before the expected proportion of the theoretical susceptible cohort being maximally infected. Fitting the theoretical SIR model, a limited persistence of VOCs in a population could explain that new VOCs replace old ones, even if the new VOC has a lower transmission rate than the preceding one. In conclusion, acquisition of potential defective mutations in VOC during an epidemic wave is a potential factor explaining the absence of resurgence of a same VOC during successive waves. Such an hypothesis is open to discussion and to rebuttal. A modified SIR model with epidemic waves of variable amplitude related not only to R0 and public health measures but also to acquisition of defective fitting in virus within a population should be tested.

The role of provincial health administration in supporting district health management teams in the Democratic Republic of Congo: eliciting an initial programme theory of a realist evaluation.

BACKGROUND: In 2006, the Ministry of Health in the Democratic Republic of Congo designed a strategy to strengthen the health system by developing health districts. This strategy included a reform of the provincial health administration to provide effective technical support to district health management teams in terms of leadership and management. The provincial health teams were set up in 2014, but few studies have been done on how, for whom, and under what circumstances their support to the districts works. We report on the development of an initial programme theory that is the first step of a realist evaluation seeking to address this knowledge gap. METHODS: To inform the initial programme theory, we collected data through a scoping review of primary studies on leadership or management capacity building of district health managers in sub-Saharan Africa, a review of policy documents and interviews with the programme designers. We then conducted a two-step data analysis: first, identification of intervention features, context, actors, mechanisms and outcomes through thematic content analysis, and second, formulation of intervention-context-actor-mechanism-outcome (ICAMO) configurations using a retroductive approach. RESULTS: We identified six ICAMO configurations explaining how effective technical support (i.e. personalised, problem-solving centred and reflection-stimulating) may improve the competencies of the members of district health management teams by activating a series of mechanisms (including positive perceived relevance of the support, positive perceived credibility of provincial health administration staff, trust in provincial health administration staff, psychological safety, reflexivity, self-efficacy and perceived autonomy) under specific contextual conditions (including enabling learning environment, integration of vertical programmes, competent public health administration staff, optimal decision space, supportive work conditions, availability of resources and absence of negative political influences). CONCLUSIONS: We identified initial ICAMO configurations that explain how provincial health administration technical support for district health management teams is expected to work, for whom and under what conditions. These ICAMO configurations will be tested in subsequent empirical studies.

Participative epidemiology and prevention pathway of health risks associated with artisanal mines in Luhihi area, DR Congo.

BACKGROUND: Health issues are associated with artisanal mining in the DR Congo. The scenario is worst when artisanal mining is done informally or with limited material and technical resources. This paper argues that the adoption of healthy practices by artisanal miners might be limited given that it involves unrealistic socio-economic, and administrative aspects and access to health risk prevention means. Making a conceptual framework on the feasibility of revolutionizing artisanal mining practices linked to health risks in the DR Congo requires trans-disciplinary interventions and researches. This case study aims at co-analyzing with actors in the Luhihi artisanal gold mine, the epidemiology of health issues. It also aims at describing the dynamics of resources that mining actors mobilize or think they can mobilize in order to prevent health risks. METHODS: A "socio-anthropological" qualitative study with "transdisciplinary methods" was carried out the Luhihi artisanal mining. Data collection tools and methods included an exploratory survey, semi-structured interviews. Focus groups (FG) mixed with proportional piling were used to support the open-ended interview discussions. The actors interviewed were selected by "convenience sampling" and the saturation principle indicated the size of the sampling. In total, 67 persons were interviewed and 5 FG each consisting of 5 to 10 mining actors were organized. Data were triangulated among respondents to ensure their veracity and an "inductive thematic data analysis" was applied. RESULTS: Key findings are the role of actors involved the organization system at the Luhihi artisanal mining site; a description of a participative epidemiology and determinants of health issues; presentation of the importance of health risks as perceived by mining actors; the constraints in the common illenesses treatment; and opportunities of collective actions for gathering resources required for the organization of healthcare services. CONCLUSION: The results are translated into a grid of powers and interests in relation to the mobilization of resources for the prevention and treatment of health issues. The dialogue for change regarding the ignorance of the actors to exposure to chemical risks such as to exposure mercury, silica, carbon monoxide, and cyanide also entailed the translation of the results. In addition, an analysis of the ability of artisanal mining actors to implement health risk prevention services was made.

Job stress, a source of hypertension among workers in Sub-Saharan Africa: a scoping review.

BACKGROUND: Hypertension remains one of the leading risk factors for cardiovascular disease. Contrasting with the high-income countries where the rates of hypertension decline, it increases in Sub-Saharan African countries. The age group most affected by hypertension is the working population. Several studies carried out in Europe, North America, and Asia, underline the influence of job stress on the occurrence of hypertension. The objective of this review was to explore current knowledge about hypertension and job stress in Sub-Saharan Africa. METHODS: We conducted a scoping review using Arksey and O'Malley's framework to synthesize findings. We searched in PubMed, Scopus, and ProQuest databases. The inclusion criteria were peer-reviewed manuscripts published on March 1, 2023, conducted among workers in Sub-Saharan Africa, reported hypertension and job stress, and using quantitative methodologies. Data were assessed independently by two researchers. RESULTS: In total, 295 articles were identified from databases. Of these, only 12 articles met the inclusion criteria and were included in the review (9 cross-sectional studies and 3 case-control studies). These studies focused on sectors reported as stressful (health, banking, education, and industries). The prevalence of hypertension varied from 14.3% to 45.9%, with a high proportion of hypertensive participants (35.4%-70.6%) who were unaware that they had hypertension. Job stress was significantly associated with hypertension (OR = 2.4 [1.5-4.4]) and stress management was inversely associated with hypertension (r = -0.14, p < 0.05). However, no study reported an existing workplace health promotion program implemented, especially regarding cardiovascular disease risk factors. CONCLUSION: Data available in the literature show that stressful working conditions may be associated with hypertension. We are faced with an increasing prevalence of hypertension among workers in Sub-Saharan Africa, where a large proportion of them are unaware that they have hypertension. Thus, there is a need to implement workplace prevention and health promotion strategies in Sub-Saharan Africa.

Understanding the mix of services for mental health care in urban DR Congo: a qualitative descriptive study.

BACKGROUND: Mental health workers (MHWs) are exposed to conflicts of competence daily when performing tasks related to the provision of mental health services. This may be linked to a lack of understanding of their tasks as caregivers and providers. Furthermore, in most low-income settings, it is unclear how the available services are organized and coordinated to provide mental health care. To understand the above, this study aimed to identify the current mix of services for mental health care in the urban Democratic Republic of the Congo (DRC). METHODS: A qualitative descriptive study was carried out in Lubumbashi from February to April 2021. We conducted 7 focus group discussions (FGDs) with 74 key informants (family members, primary care physicians, etc.) and 13 in-depth interviews (IDIs) with key informants (traditional healers, psychiatrists, etc.). We performed a qualitative content analysis, guided by an analytical framework, that led to the development of a comprehensive inventory of MHWs from the household level to specialized facilities, exploring their tasks in care delivery, identifying existing services, and defining their current organization. RESULTS: Analysis of transcripts from the FGDs and IDIs showed that traditional healers and family caregivers are the leading providers in Lubumbashi. The exploration of the tasks performed by MHWs revealed that lifestyle, traditional therapies, psychotherapy, and medication are the main types of care offered/advised to patients. Active informal caregivers do not currently provide care corresponding to their competencies. The rare mental health specialists available do not presently recognize the tasks of primary care providers and informal caregivers in care delivery, and their contribution is considered marginal. We identified five types of services: informal services, traditional therapy services, social services, primary care services, and psychiatric services. Analyses pointed out an inversion of the ideal mix of these services. CONCLUSIONS: Our findings show a suboptimal mix of services for mental health and point to a clear lack of collaboration between MHWs. There is an urgent need to clearly define the tasks of MHWs, build the capacity of nonspecialists, shift mental health-related tasks to them, and raise awareness about collaborative care approaches.

Are surgeons ready to get the COVID-19 vaccine?

BACKGROUND: Vaccination against COVID-19 has started in several countries already and is on its way in others. However, there is an important hesitance towards the vaccine. The aim of this study is to evaluate the vaccination hesitance and main concerns towards the vaccine among surgeons. METHODS: An anonymous survey of 16 questions was sent to 138 Belgian surgeons before the start of vaccination in Belgium. The questions were divided into sections, evaluating demographics, COVID-19 test status and symptoms, the surgeon's opinion on the COVID-19 vaccination and their main concerns. RESULTS: Ninety-three out of 138 surgeons (67.4%) completed the survey: two-third of them were residents. Sixty-nine surgeons (74.2%) do want to get vaccinated. Forty-two surgeons (45.2%) feel like they do not have enough information about the vaccine. Residents feel significantly more underinformed than consultants (52.3% and 29.0%, respectively). Surgeons who feel to be well-informed are more willing to get vaccinated (92.2%) compared to those who feel to have a lack of information (52.4%). The main concerns among surgeons include effectiveness (26.9%), safety and side effects (19.4%) and organisation and vaccination strategy (12.9%). Twenty-five surgeons (26.9%) have no concerns at all. CONCLUSION: Most surgeons (74.2%) are ready for their COVID-19 vaccine. However, some of the surgeons are still doubtful about the vaccine. A lack of information plays a major role in their scepticism. A strong communication strategy is necessary to educate, reassure and motivate surgeons to get vaccinated.

Implementation of a model of awareness-raising for taxi motorcyclists in Benin in relation to helmet use: a quasi-experimental study.

BACKGROUND: This study aims to test the effectiveness of an awareness-raising model designed based on the theory of planned behaviour regarding helmet use for motorcycle taxi drivers. METHODS: This quasi-experimental study took place in the cities of Parakou (intervention group) and Porto Novo (control group). Over a three-month period, a package of awareness-raising activities, based on the theory of planned behaviour, have been implemented in the intervention area. Data relate to knowledge, attitudes and practices regarding helmet use was collected prospectively before the intervention, at the end, and 6 months later. Stata 15 was used for data analysis. Chi-square or Fisher, Student's or Kruskal-Wallis tests was carried out. The difference-in-difference method was used to determine the specific effect of the awareness activities. RESULTS: After the intervention, there was an improvement in the total score in both groups compared to baseline. The total score increased by 0.2 (0.06-0.3) in the experimental group when the number of sessions attended increased by one (p = 0.005). The difference-in-difference estimator measured among subjects who attended at least one awareness session, controlling for socio-demographic variables, showed a significantly higher difference in the total score of subjects in the experimental group compared to those in the control group both at the end of the interactive sessions and 6 months later. CONCLUSION: This model improves the helmet-wearing behaviour of motorbike taxi drivers in the experimental area. It could be adapted and applied to other socio-professional groups and other types of users.

Prediction ability of vector species, environmental characteristics and socio-economic factors for malaria risk in Sub-Saharan African Countries.

Malaria remains a major public health problem, causing 435,000 deaths in 2017. The objective of this study was to estimate the prediction ability of vector species associated with the prediction power of environmental and socio-economic factors for malaria risk. Logistic regression was used for malaria risk estimation. A Radial Basis Function model was applied for estimating the predictive ability of Anopheles species, environmental and socio-economic factors. The lowest fever prevalence was found where Anopheles melas was dominant. Anopheles coluzzi and Anopheles gambiae were the dominant species where prevalence of malaria was high. Altitude, country and vector species were the best predictive factors. Anopheles arabiensis, An. coluzzi and An. gambiae were most common in urban areas. This study will improve the prediction of malaria risk in targeted areas. We have observed how important it is to adapt health policies according to the dominant malaria vector in a region.

Évaluation de la mise en œuvre de la sécurité routière au Bénin en 2019.

OBJECTIVE: The study aims to assess the level of implementation of road safety interventions in Benin. METHOD: The research is based on an evaluative study of road safety aimed to analyze the implementation and logic of road safety interventions, conducted in Benin in 2019. It combined a review of the gray literature and a qualitative component. The data were collected through documents and interviews in structures involved in road safety management. RESULTS: Road safety was a national priority with one lead institution and several structures involved. There was a lack of consensus among stakeholders, insufficient framework documents, resources, legislative texts, and study data. Few roads were in good condition and very few allowed the separation of two-wheeled vehicles. The vehicle fleet was outdated. Various activities were carried out to raise awareness, to educate the population and to enforce the texts but they were insufficient and poorly coordinated. Reference hospitals had the minimum service to deal with trauma cases. The interventions had not yet resulted in a reduction in the number of injuries and fatalities by accidents, which was increasing. CONCLUSION: Benin has made great efforts in the area of road safety. However, there are still some shortcomings to take into account.

A realist evaluation of the continuum of HIV services for men who have sex with men.

BACKGROUND: Men who have Sex with Men (MSM) represent the risk group that are disproportionately most affected by the human immunodeficiency virus (HIV) and continue to drop-off from the steps of the continuum of HIV services that have been adopted to overcome poor engagement and retention in care. This realist evaluation aimed at: (1) describing the evaluation carried out in Haiti aiming to ascertain why, how and under which circumstances MSM are linked and retained along the continuum, (2) assessing the outcomes of this approach and (3) exploring the motivators and facilitators for the HIV continuum of services through mechanisms and pathways. METHODS: Guided by a realist approach, first, an initial program theory (IPT) was developed based on literature and frameworks review, participant observations and discussions with stakeholders. Then, the IPT was tested using a mixed method explanatory study: a quantitative phase to build the continuum from a cross-sectional analysis, and a qualitative phase to explore the motivators and facilitators related to proper linkages along the continuum. Finally, the IPT was refined by eliciting the mechanisms and pathways for outcomes improvement. RESULTS: The results showed that the current service delivery model is suboptimal in identifying, engaging, linking and retaining MSM, resulting in loss to follow-up at every step of the continuum and failure to fully realize the health and prevention benefits of antiretroviral. However, the mechanisms through which linkages across the continuum can be improved are: self-acceptance, sense of community support and sense of comprehensive and tailored HIV services. These mechanisms are based on 10 different pathways: self-esteem, awareness and pride, perception of HIV risk, pcceptance and HIV status, addressing community stigma, strengthening of MSM organizations and community networks, societal acceptation and tolerance, stigma reduction training for healthcare providers, engagement of peers as educators and navigators and, adapted services delivery through drug dispensing points and mobile technology and financial assistance. CONCLUSIONS: The study findings show that engagement, adherence and retention to the continuum of HIV service for MSM are affected by a multi-layer of factors, thus highlighting the importance of taking a comprehensive approach to improve the program.

Implementation of a model of awareness-raising for taxi motorcyclists in Benin in relation to helmet use: protocol for a quasi-experimental study.

BACKGROUND: In the large cities of Benin, motorcycle taxi drivers, mainly between the ages of 20 and 40, are particularly exposed to accidents due to their profession. User awareness, along with legislative reforms and enforcement measures, would reduce the incidence of crashes and injuries. This study aims to test the effectiveness of an awareness-raising model regarding helmet use for motorcycle taxi drivers. METHODS: This is a quasi-experimental study that will take place in the cities of Parakou (intervention group) and Porto Novo (control group). Over a three-month period, a package of awareness-raising activities will be implemented in the intervention area, targeting a group of motorcycle taxi drivers. The messages to be developed for awareness-raising will focus on the most frequently influencing factors, as identified by the baseline collection. These key messages will be disseminated through various tools and communication channels (banners, motorcycle stickers and motorcycle taxi uniforms, interactive sessions). Data will be collected prospectively via a self-reported questionnaire and observation, carried out before the intervention, at the end, and 6 months later. The data will relate to knowledge, attitudes and practices regarding helmet use. The analysis will compare the indicators between the groups, as well as between the pre- and post-intervention phase. The KoboCollect software will be used for data entry and processing, and Stata 15 will be used for data analysis. Chi-square or Fisher, Student's or Kruskal-Wallis tests will be used for the comparisons. The difference-in-difference method will be used to determine the specific effect of the awareness activities. DISCUSSION: This study will assess the contribution of awareness messages to changing the behaviour of motorcycle taxi drivers by determining the specific effect of the intervention.

Effects of implementing a postabortion care strategy in Kinshasa referral hospitals, Democratic Republic of the Congo.

OBJECTIVES: To evaluate the effects of the implementation of a postabortion care (PAC) strategy in Kinshasa referral hospitals, this study analyzed the quality of postabortion care services, including postabortion contraception, and the duration of hospitalization. METHODOLOGY: We estimated the effects of the PAC strategy using a quasi-experimental study by evaluating the outcomes of 334 patients with the diagnosis of a complication of induced abortion admitted to 10 hospitals in which the PAC strategy was implemented compared to the same outcomes in 314 patients with the same diagnosis admitted to 10 control facilities from 01/01/2016 to 12/31/2018. In response to government policy, the PAC strategy included the treatment of abortion complications with recommended uterine evacuation technology, the family planning counseling and service provision, linkages with other reproductive health services, including STI evaluation and HIV counseling and/or referral for testing, and partnerships between providers and communities. The information was collected using a questionnaire and stored using open data kit software. We supplemented this information with data abstracted from patient records, facility registries of gynecological obstetrical emergencies, and family planning registries. We analyzed data and developed regression models using STATA15. Thus, we compared changes in use of specific treatments and duration of hospitalization using a "difference-in-differences" analysis. RESULTS: The implementation of PAC strategy in Kinshasa referral hospitals has resulted in the utilization of WHO recommended uterine evacuation method MVA (29.3% more in the experimental structures, p = 0.025), a significant decline in sharp-curettage (19.3% less, p = 0.132), and a decline in the duration of hospitalization of patients admitted for PAC (1 day less, p = 0.020). We did not observe any change in the use of PAC services, mortality, and the provision of post abortion contraception. CONCLUSION: Despite significant improvement in the management of PAC, the uptake in WHO approved technology-namely MVA, and the duration of hospitalization, these outcomes while a significant improvement for DRC, indicate that additional quality improvement strategies for management of PAC and risk-mitigating strategies to reduce barriers to care are required.

HIV among men who have sex with men in the Caribbean: reaching the left behind.

OBJECTIVES: To present the epidemiology, social and cultural factors driving the HIV epidemic among men who have sex with men (MSM) in the Caribbean region and to highlight the regional and national responses, and what remains to be addressed to close the gaps in order to ending AIDS by 2030. METHODS: A literature review was performed in the following databases: PubMed and Scopus. Articles published in the past 10 years were selected. The outcomes of interest were sociocultural risk factors, description of regional and national efforts and potential challenges and barriers to effective control of the epidemic among MSM. This report concentrates exclusively on publications related to MSM living in the Caribbean countries. RESULTS: 11 peer-reviewed studies, 9 grey literature reports and programme frameworks were thematically analysed. The prevalence of HIV among MSM is high and the rates also do vary among Caribbean countries. Several factors influence the epidemic among MSM in the Caribbean but stigma and discrimination underlie the social vulnerability and play a central role in driving the HIV epidemic. CONCLUSIONS: To end the AIDS epidemic by 2030, MSM can no longer be kept unchecked in the era of the Sustainable Development Goals with the motto 'Leave no one behind'.

Extent of induced abortions and occurrence of complications in Kinshasa, Democratic Republic of the Congo.

BACKGROUND: Due to a lack of relevant data on induced abortions in the Democratic Republic of the Congo (DRC) as well as the persistence of maternal deaths in the country, this study aims to analyse the extent of induced abortions and occurrence of complications in Kinshasa. METHODOLOGY: This cross-sectional study was conducted with a sample of 460 women who were interviewed about their experiences as females, and provided information of 1444 women of childbearing age living in Kinshasa. Respondents' households were selected to represent the five types of residential quarters in Kinshasa, differentiated by cultural, socioeconomic, and infrastructural characteristics. Information was collected using a survey form and analyzed. RESULTS: Among all confidantes included in the study, 5.5% (95% CI: 4.4-6.8%) had induced abortions during 2015, a rate of 55.0 abortions per 1000 women of childbearing age. This practice was significantly performed amongst single/separated/divorced women; those without formal education, or primary-school education, and women who consumed excessive alcohol. Most abortions were induced by the administration of high doses of medication, by the women themselves or by health workers. A percentage of 51.9% (95%CI: 40.4-63.3%) of induced abortions led to complications, which were predominantly haemorrhagic. Moreover, 39% of patients had a complication for which they sought care, and of whom 12.5% had genital trauma or uterine perforation/intestinal necrosis. CONCLUSION: Induced abortion is a public health problem in Kinshasa due to its frequency of practice, the complications that occur, and the absence of major surgeries in the health care package offered by the health centres or dispensaries that also provide the treatment of some serious complications. Thus, there is a need to focus on the enhancement of the health care package offered by health centres to include appropriate measures in favour of maternal health.

Analysis of induced abortion-related complications in women admitted to the Kinshasa reference general hospital: a tertiary health facility, Democratic Republic of the Congo.

BACKGROUND: Due to a lack of relevant data on induced abortions in the Democratic Republic of the Congo (DRC) as well as the persistence of maternal deaths in the country, this study aims to analyse the induced abortion-related complications in women who were admitted to the Kinshasa Reference General Hospital (KRGH). METHODS: This is a cross-sectional study on 368 obstetric and gynecological patients who were admitted, as emergency cases, to the KRGH during 2014. This health facility was selected because it is a tertiary health facility with an obstetric and gynecological emergency unit most used in the city of Kinshasa. Patient data were collected from patient records and analyzed. RESULTS: From the 368 patients admitted to receive obstetric and gynecological emergency care services in 2014 at the KRGH, 12.2% (95% CI: 9.1-16.1%) had complications due to induced abortion that was significantly diagnosed to adolescents (p <  0.001), single or separated or divorced women or widow(p <  0.001), and to patients with history of one or several induced abortions(p <  0.001). The median duration of hospitalization was ten days and this period of time was significantly longer for the patients who underwent surgery for pelvic peritonitis due to uterine perforation(p <  0.001) compared with the group of patients who underwent Caesarean section/hysterectomy. The mortality rate related to them is 37.8% (95% CI: 23.8-53.5%) with an increase of risk of death in the presence of a post-abortive pelvic peritonitis-type complication, 56.3% of deaths occurred after two days of hospitalization. CONCLUSION: The complications of induced abortions are a major public health problem due to its frequency among patients admitted to the KRGH, as well as the poor medical management, and mortality percentage related to them. Therefore, there is a need to understand the reason for the poor medical management to fill in and provide an adequate intervention package.

Concentration-response curve and cumulative effects between ozone and daily mortality: an analysis in Wallonia, Belgium.

Many studies have shown an association between ozone and mortality. However, little data is available on the cumulative effects of ozone on health. A time-series analysis using a Poisson regression was used to measure the impact of ozone on non-traumatic mortality in Wallonia over the period 2000-2012. Initially, a single-lag model was tested. Then a distributed-lag non-linear model was used in order to verify the cumulative effects of ozone on mortality. Our study confirms the existence of an association between ozone and mortality. The linear model without threshold shows a higher sensitivity in persons aged 75 and over (ERR = 0.7, 95 % CI: 0.4; 1.0 %) compared to younger people (ages 25-74) (ERR = 0.2, 95 % CI: - 0.2; 0.6 %). Taking cumulative effects into account, men and women aged 25-74 have an ozone sensitivity equivalent to those over 75.

An in-depth investigation of the causes of persistent low membership of community-based health insurance: a case study of the mutual health organisation of Dar Naïm, Mauritania.

BACKGROUND: Persistent low membership is observed in many community-based health insurance (CBHI) schemes in Africa. Causes for low membership have been identified and solutions suggested, but this did not result in increased membership. In this case study of the mutual health organisation of Dar Naïm in Mauritania we explore the underlying drivers that may explain why membership continued to stagnate although several plans for change had been designed. METHODS: We used a systems approach focussed on processes, underlying dynamics and complex interactions that produce the outcomes, to delve into 10 years of data collected between 2003 and 2012. We used qualitative research methods to analyse the data and interpret patterns. RESULTS: Direct causes of stagnation and possible solutions had been identified in the early years of operations, but most of the possible solutions were not implemented. A combination of reasons explains why consecutive action plans were not put into practice, showing the complexity of implementation and the considerable management capacity required, as well as the challenges of integrating a novel organisational structure into exiting social structures. CONCLUSIONS: For any CBHI project aiming at high membership, skilled professional management seems essential, with capacity to question and adapt routine procedures and interpret interactions within the wider society. Countries that include community-based health insurance in their strategic plan towards universal coverage will have to pay more attention to management capacity and the minutiae of implementation.

Task shifting in the management of hypertension in Kinshasa, Democratic Republic of Congo: a cross-sectional study.

BACKGROUND: The Democratic Republic of the Congo (DRC) is characterized by a high prevalence of hypertension (HTN) and a high proportion of uncontrolled HTN, which is indicative of poor HTN management. Effective management of HTN in the African region is challenging due to limited resources, particularly human resources for health. To address the shortage of health workers, the World Health Organization (WHO) recommends task shifting for better disease management and treatment. Although task shifting from doctors to nurses is being implemented in the DRC, there are no studies, to the best of our knowledge, that document the association between task shifting and HTN control. The aim of this study was to investigate the association between task shifting and HTN control in Kinshasa, DRC. METHODS: We conducted a cross-sectional study in Kinshasa from December 2015 to January 2016 in five general referral hospitals (GRHs) and nine health centers (HCs). A total of 260 hypertensive patients participated in the study. Sociodemographic, clinical, health care costs and perceived health care quality assessment data were collected using a structured questionnaire. To examine the association between task shifting and HTN control, we assessed differences between GRH and HC patients using bivariate and multivariate analyses. RESULTS: Almost half the patients were female (53.1%), patients' mean age was 59.5 ± 11.4 years. Over three-fourths of patients had uncontrolled HTN. There was no significant difference in the proportion of GRH and HC patients with uncontrolled HTN (76.2% vs 77.7%, p = 0.771). Uncontrolled HTN was associated with co-morbidity (OR = 10.3; 95% CI: 3.8-28.3) and the type of antihypertensive drug used (OR = 4.6; 95% CI: 1.3-16.1). The mean healthcare costs in the GRHs were significantly higher than costs in the HCs (US$ 34.2 ± US$3.34 versus US$ 7.7 ± US$ 0.6, respectively). CONCLUSION: Uncontrolled HTN was not associated with the type of health facility. This finding suggests that the management of HTN at primary healthcare level might be just as effective as at secondary level. However, the high proportion of patients with uncontrolled HTN underscores the need for HTN management guidelines at all healthcare levels.

Prevalence and determinants of use of complementary and alternative medicine by hypertensive patients attending primary health care facilities in Kinshasa, Democratic Republic of the Congo: a cross-sectional study.

BACKGROUND: In the Democratic Republic of the Congo the control of hypertension is poor, characterized by an increasing number of reported cases of hypertension related complications. Poor control of hypertension is associated with non-adherence to antihypertensive medication. It is well established that the use of complementary and alternative medicine is one of the main factors of non-adherence to antihypertensive medication. The aim of this study is to determine the prevalence and factors associated with the use of complementary and alternative medicine. METHODS: A cross-sectional study was carried out at the Kinshasa Primary Health-care (KPHC) facilities network in November 2014. A structured interview questionnaire was administrated to a total of 280hypertensive patients. Complementary and alternative medicine were defined according to the National Institute of Health classification as a group of diverse medical and healthcare systems, practices, and products that are not presently considered to be part of conventional medicine. Data were summarized using proportion and mean (with standard deviation). The student's t test and χ2 test were used respectively for mean and proportion comparison. Logistic regression analysis identified determinants of the use of complementary and alternative medicine. RESULTS: The prevalence of use of complementary and alternative medicine was 26.1% (95% CI: 20.7% - 31.8%).Determinants of use of complementary and alternative medicine included misperception about hypertension curability (OR = 2.1; 95%CI: 1.1-3.7) and experience of medication side effects (OR = 2.9; 95%CI: 1.7-5.1). CONCLUSION: The use of CAM for hypertensive patients is a major problem; antihypertensives with fewer side effects must be emphasized. Religious leaders must become involved in the communication for behavioral change activities to improve the quality of life for hypertensive patients.

Importance of risk factors associated with malaria for Sub-Saharan African children.

To assess the importance of malaria risk factors for children in sub-Saharan African countries. 61,292 children of 16 countries from DHS and MIS surveys were included in analysis. A regression model with analyse of variance and plots of mean decrease accuracy and mean decrease Gini indices were performed. The most important risk factor was the country and it contributed 52.33 % to the variance of the model. Wealth status of the child's family was the first socio-economic factor which contributed more to the difference of malaria risk among African children. There was no geographic factor among the five most important variables. Quantity of precipitation was the sixth most important factor. Our study has the potential for driving control effort in the fight against malaria in the continent which represent the majority of global malaria cases. The study indicates that, when implementing health policies, community characteristics must be taken into account.
