What makes knowledge translation work in practice? Lessons from a demand-driven and locally led project in Cameroon, Jordan and Nigeria.

BACKGROUND: Over the years, the knowledge translation (KT) field has moved from promoting linearized models to embracing the importance of interaction and learning. Likewise, there is now increased attention on the transfer of KT approaches to new environments. Some scholars, however, have warned that ideas about transferability still hinge on linear thinking and doing. In the current study, we therefore sought to use a more reflexive approach to KT and to study how actors align KT approaches with their local environments. METHODS: Our (auto) ethnographic study took place in a wider KT project. This project intended to combine three components: (1) co-organizing demand-driven, locally led and embedded KT cycles in Cameroon, Jordan, and Nigeria, (2) building upon established KT methods and (3) equipping and empowering local teams. We conducted 63 semi-structured interviews with key KT actors, observed 472 h of KT practices, and collected a paper trail of documents. At the same time, we also compiled project exchanges, such as project documents, plans, protocols, field notes, meeting notes and an archive of (email) correspondence between project members. We analysed all data abductively. RESULTS: We show that there were numerous moments where the design of our project indeed enabled us to align with local practices and needs. Yet this often did not suffice, and the project design sometimes conflicted with other logics and values. By analysing these tensions, we want to show that doing KT work which acts upon different values and knowledges and is sensitive towards the different effects that it produces demands both structuring projects in a specific way and requires significant alignment work of KT actors in practice. CONCLUSIONS: We show that practising KT more reflexively relies on two important conditions. First, KT projects have to be structured with sufficient discretionary space. Second, even though the structure of a project is important, there will be continuous need for alignment work. It is important to facilitate such alignment work and to further support it. In the discussion of this paper, we therefore articulate three design principles and three sensitivities. These elements can be used to make future KT projects more reflexive and sensitive to (social) complexity.

[Primary tuberculosis of the cavum: An unusual diagnosis]. / Tuberculose primitive du cavum : un diagnostic peu commun.

Primary tuberculosis of the cavum is a rare entity. It can occur at any age, especially between the second and ninth decade. We report the case of a 17-years-old patient with nasal obstruction and left laterocervical adenomegaly. A cervico-facial CT scan showed a suspicious looking tumor process of the nasopharynx. Histological analysis of the biopsies taken showed chronic granulomatous inflammation with necrosis and the absence of tuberculosis lesions in the usual sites, especially the lungs, led to the diagnosis of primary tuberculosis of the cavum. There was a good evolution on antituberculosis drugs. This unusual location can be a source of difficulties and delay in diagnosis, especially because of the clinical presentation, which suggests a nasopharyngeal tumour. In developing countries, where this disease remains relatively endemic, cross-sectional imaging techniques and histopathological analysis are of great interest for the management of patients.

Government regulation of private health insurance.

BACKGROUND: The strain on public resources to meet the healthcare needs of populations through publicly-provided health insurance programmes is increasing and many governments turn to private health insurance (PHI) to ease the pressure on government budgets. With the goal of improving access to basic health care for citizens through PHI programmes, several high-income countries have developed strong regulations for PHI schemes. Low- and middle-income countries have the opportunity to learn from this experience to optimise PHI. If poorly regulated, PHI can hardly achieve an adequate quantity or quality of population coverage, as can be seen in the USA where a third of adults younger than 65 years of age have no insurance, sporadic coverage or coverage that exposes them to high out-of-pocket healthcare costs. OBJECTIVES: To assess the effects of policies that regulate private health insurance on utilisation, quality, and cost of health care provided. SEARCH METHODS: In November 2019 we searched CENTRAL; MEDLINE; Embase; Sociological Abstracts and Social Services Abstracts; ICTRP; ClinicalTrials.gov; and Web of Science Core Collection for papers that have cited the included studies. This complemented the search conducted in February 2017 in IBSS; EconLit; and Global Health. We also searched selected grey literature databases and web-sites.  SELECTION CRITERIA: Randomised trials, non-randomised trials, interrupted time series (ITS) studies, and controlled before-after (CBA) studies conducted in any population or setting that assessed one or more of the following interventions that governments use to regulate private health insurance: legislation and licensing, monitoring, auditing, and intelligence. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed study eligibility, extracted data, and assessed risk of bias and certainty of the evidence resolving discrepancies by consensus. We planned to summarise the results (using random-effects or fixed-effect meta-analysis) to produce an overall summary if an average intervention effect across studies was considered meaningful, and we would have discussed the implications of any differences in intervention effects across studies. However, due to the nature of the data obtained, we have provided a narrative synthesis of the findings. MAIN RESULTS: We included seven CBA studies, conducted in the USA, and that directly assessed state laws on cancer screening. Only for-profit PHI schemes were addressed in the included studies and no study addressed other types of PHI (community and not for-profit). The seven studies were assessed as having 'unclear risk' of bias. All seven studies reported on utilisation of healthcare services, and one study reported on costs. None of the included studies reported on quality of health care and patient health outcomes. We assessed the certainty of evidence for patient health outcomes, and utilisation and costs of healthcare services as very low. Therefore, we are uncertain of the effects of government mandates on for-profit PHI schemes. AUTHORS' CONCLUSIONS: Our review suggests that, from currently available evidence, it is uncertain whether policies that regulate private health insurance have an effect on utilisation of healthcare services, costs, quality of care, or patient health outcomes. The findings come from studies conducted in the USA and might therefore not be applicable to other countries; since the regulatory environment could be different. Studies are required in countries at different income levels because the effects of government regulation of PHI are likely to differ across these income and health system settings. Further studies should assess the different types of regulation (including regulation and licensing, monitoring, auditing, and intelligence). While regulatory research on PHI remains relatively scanty, future research can draw on the rich body of research on the regulation of other health financing interventions such as user fees and results-based provider payments.

Assessing and coping with the financial burden of computed tomography utilization in Limbe, Cameroon: a sequential explanatory mixed-methods study.

BACKGROUND: There has been a significant increase in computed tomography (CT) utilization over the past two decades with the major challenges being a high exposure to ionizing radiation and rising cost. In this study we assess the risk of financial hardship after CT utilization and elaborate on how users adapt and cope in a sub-Saharan context with user fee for services and no national health insurance policy. METHODS: We carried out a sequential explanatory mixed methods study with a quantitative hospital-based survey of CT users followed by in-depth interviews of some purposively selected participants who reported risk of financial hardship after CT utilization. Data was summarized using frequencies, percentages and 95% confidence intervals. Logistic regression was used in multivariable analysis to determine predictors of risk of financial hardship. Identified themes from in-depth interviews were categorized. Quantitative and qualitative findings were integrated. RESULTS: A total of 372 participants were surveyed with a male to female sex ratio of 1:1.2. The mean age (standard deviation) was 52(17) years. CT scans of the head and facial bones accounted for 63% (95%CI: 59-68%) and the top three indications were suspected stroke (27% [95%CI: 22-32%]), trauma (14% [95%CI: 10-18%]) and persistent headaches (14% [95%CI: 10-18%]). Seventy-two percent (95%CI: 67-76%) of the respondents reported being at risk of financial hardship after CT utilization and predictors in the multivariable analysis were a low socioeconomic status (aOR: 0.19 [95%CI: 0.10-0.38]; p < 0.001), being unemployed or retired (aOR: 11.75 [95%CI: 2.59-53.18]; p = 0.001) and not having any form of health insurance (aOR: 3.59 [95%CI: 1.31-9.85]; p = 0.013). Coping strategies included getting financial support from family and friends, borrowing money and obtaining discounts from the hospital administration and staff. CONCLUSION: No health insurance ownership, being unemployed or retired and a low socioeconomic status are associated with financial hardship after CT utilization. Diverse coping strategies are utilized to lessen the financial burden, some with negative consequences. Minimizing out-of-pocket payments and/or the direct cost of CT can reduce this financial burden and improve CT access.

Medium-term Survival Following of Stroke in Yaoundé (Cameroon): a prospective observational cohort study.

BACKGROUND: With 5.7 million deaths per year, stroke is the second cause of mortality worldwide, and 70% of these deaths occur in developing countries especially in relation to inappropriate clinical pathways and resources. The aim of our study was to assess the survival rate of stroke patients within 90 days and to identify its determinants. METHODS: It was a prospective observational cohort study over a period of 90 days after stroke. Patients were recruited between February and May 2015 in two tertiary hospitals in Yaoundé. The mortality rate was obtained by the Kaplan-Meier method. Multivariate analysis was performed using a Cox proportional hazards model. RESULTS: Sixty-six patients were enrolled of which 54 were followed up to 90 days. The overall mortality rate was 23.2% (95% CI: 12.5-87.5), more than two-thirds of the deaths occurred within the first 30 days. The mortality rates at days 14, 30, 60 day were 9.1% (95% CI: 3.0-16.7), 14.3% (95% CI: 6.3-23.8) and 21.1% (95% CI: 10.5-31.6) respectively. High systolic blood pressure and a low Glasgow coma score on admission were independent risk factors of mortality at 90 days. CONCLUSIONS: The stroke related mortality compels appropriate collective mobilization for an early and adequate management of stroke patients.

Two decades of tobacco use prevention and control policies in Cameroon: results from the analysis of non-communicable disease prevention policies in Africa.

BACKGROUND: Tobacco use is the leading cause of preventable death in the world today. In 2010, the World Health Organization (WHO) proposed efficient and inexpensive "best buy" interventions for prevention of tobacco use including: tax increases, smoke-free indoor workplaces and public places, bans on tobacco advertising, promotion and sponsorship, and health information and warnings. This paper analyzes the extent to which tobacco use prevention policies in Cameroon align with the WHO tobacco "best buy" interventions. It further explores the context, content, formulation and implementation level of these policies. METHODS: This was a case study combining a structured review of 19 government policy documents related to tobacco use and prevention, in-depth interviews with 38 key stakeholders and field observations. The Walt and Gilson's policy analysis triangle was used to describe and interpret the context, content, processes and actors during the formulation and implementation of tobacco prevention and control policies. Direct observations ascertained the level of implementation of some selected policies. RESULTS: Twelve out of 19 policies for tobacco use and prevention address the WHO "best buy" interventions. Cameroon policy formulation was driven locally by the social context of non-communicable diseases, and globally by the adoption of the WHO Framework Convention on Tobacco Control. These policies incorporated at a certain level all four domains of tobacco use "best buy" interventions. Formulating policy on smoke-free areas was single-sector oriented, while determining tobacco taxes and health warnings was more complex utilizing multisectoral approaches. The main actors involved were ministerial departments of Health, Education, Finances, Communication and Social Affairs. The level of implementation varied widely from one policy to another and from one region to another. Political will, personal motivation and the existence of formal exchange platforms facilitated policy formulation and implementation, while poor resource allocation and lack of synergy constituted barriers. CONCLUSIONS: Despite actions made by the Government, there is no real political will to control tobacco use in Cameroon. Significant shortcomings still exist in developing and/or implementing comprehensive tobacco use and prevention policies. These findings highlight major gaps as well as opportunities that can be harnessed to improve tobacco control in Cameroon.

Characteristics and determinants of clinical symptoms in radiographic lumbar spinal stenosis in a tertiary health care centre in sub-Saharan Africa.

BACKGROUND: Lumbar spinal stenosis (LSS) refers to narrowing of the lumbar central spinal canal, lateral recess, and/or neuro-foramina. Radiographic LSS plays an important role in clinical LSS but is not solely accountable for the presence of symptoms. We sought to characterise clinical LSS and to determine factors associated with presence of symptoms of LSS in patients with radiographic LSS in a sub Saharan Africa setting. METHODS: After prior ethical clearance, a case control study was done in a tertiary hospital in Douala-Cameroon, including 105 patients with radiographic LSS: 57 with symptoms of LSS (cases) and 58 with no symptoms (controls). Spinal stenosis was assessed using computed tomography (CT) scans. Data were analysed using SPSS version 23. RESULTS: The mean age of our study participants was 53.4 ± 13.1 years. The mean age of onset of symptoms of LSS was 50.3 ± 11.6 years and the most common symptoms were Low back pain (100.0%), radicular symptoms (98.2%) and neurogenic claudication (98.2%). Obesity (p < 0.001) and a high waist circumference (p = 0.002) were significantly associated with presence of LSS symptoms in persons with radiographic LSS. After adjusting for body mass index, a positive family history of low back pain (p = 0.004), vertebra lesion at L2 (p = 0.034), L3 (p = 0.002), L4 (p = 0.025) and multiple (p = 0.008) levels, degenerative disc protrusion (p = 0.044), disc lesion at L3-L4 (p = 0.001), L4-L5 (p = 0.011) and multiple (p = 0.046) levels were significantly associated with presence of symptoms of LSS in persons with radiographic LSS. CONCLUSION: Characteristics of clinical LSS have been described in this sub-Saharan Africa population. Obesity, a high waist circumference and a positive family history of low back pain are significantly associated with presence of symptoms of LSS in persons with radiographic LSS.

Improving maternal and child health policymaking processes in Nigeria: an assessment of policymakers' needs, barriers and facilitators of evidence-informed policymaking.

BACKGROUND: In Nigeria, interest in the evidence-to-policy process is gaining momentum among policymakers involved in maternal, newborn and child health (MNCH). However, numerous gaps exist among policymakers on use of research evidence in policymaking. The objective of this study was to assess the perception of MNCH policymakers regarding their needs and the barriers and facilitators to use of research evidence in policymaking in Nigeria. METHODS: The study design was a cross-sectional assessment of perceptions undertaken during a national MNCH stakeholders' engagement event convened in Abuja, Nigeria. A questionnaire designed to assess participants' perceptions was administered in person. Group consultations were also held, which centred on policymakers' evidence-to-policy needs to enhance the use of evidence in policymaking. RESULTS: A total of 40 participants completed the questionnaire and participated in the group consultations. According to the respondents, the main barriers to evidence use in MNCH policymaking include inadequate capacity of organisations to conduct policy-relevant research; inadequate budgetary allocation for policy-relevant research; policymakers' indifference to research evidence; poor dissemination of research evidence to policymakers; and lack of interaction fora between researchers and policymakers. The main facilitators of use of research evidence for policymaking in MNCH, as perceived by the respondents, include capacity building for policymakers on use of research evidence in policy formulation; appropriate dissemination of research findings to relevant stakeholders; involving policymakers in research design and execution; and allowing policymakers' needs to drive research. The main ways identified to promote policymakers' use of evidence for policymaking included improving policymakers' skills in information and communication technology, data use, analysis, communication and advocacy. CONCLUSION: To improve the use of research evidence in policymaking in Nigeria, there is a need to establish mechanisms that will facilitate the movement from evidence to policy and address the needs identified by policymakers. It is also imperative to improve organisational initiatives that facilitate use of research evidence for policymaking.

Health system and community level interventions for improving antenatal care coverage and health outcomes.

BACKGROUND: The World Health Organization (WHO) recommends at least four antenatal care (ANC) visits for all pregnant women. Almost half of pregnant women worldwide, and especially in developing countries do not receive this amount of care. Poor attendance of ANC is associated with delivery of low birthweight babies and more neonatal deaths. ANC may include education on nutrition, potential problems with pregnancy or childbirth, child care and prevention or detection of disease during pregnancy.This review focused on community-based interventions and health systems-related interventions. OBJECTIVES: To assess the effects of health system and community interventions for improving coverage of antenatal care and other perinatal health outcomes. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (7 June 2015) and reference lists of retrieved studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs), quasi-randomised trials and cluster-randomised trials. Trials of any interventions to improve ANC coverage were eligible for inclusion. Trials were also eligible if they targeted specific and related outcomes, such as maternal or perinatal death, but also reported ANC coverage. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS: We included 34 trials involving approximately 400,000 women. Some trials tested community-based interventions to improve uptake of antenatal care (media campaigns, education or financial incentives for pregnant women), while other trials looked at health systems interventions (home visits for pregnant women or equipment for clinics). Most trials took place in low- and middle-income countries, and 29 of the 34 trials used a cluster-randomised design. We assessed 30 of the 34 trials as of low or unclear overall risk of bias. Comparison 1: One intervention versus no interventionWe found marginal improvements in ANC coverage of at least four visits (average odds ratio (OR) 1.11, 95% confidence interval (CI) 1.01 to 1.22; participants = 45,022; studies = 10; Heterogeneity: Tau² = 0.01; I² = 52%; high quality evidence). Sensitivity analysis with a more conservative intra-cluster correlation co-efficient (ICC) gave similar marginal results. Excluding one study at high risk of bias shifted the marginal pooled estimate towards no effect. There was no effect on pregnancy-related deaths (average OR 0.69, 95% CI 0.45 to 1.08; participants = 114,930; studies = 10; Heterogeneity: Tau² = 0.00; I² = 0%; low quality evidence), perinatal mortality (average OR 0.98, 95% CI 0.90 to 1.07; studies = 15; Heterogeneity: Tau² = 0.01; I² = 58%; moderate quality evidence) or low birthweight (average OR 0.94, 95% CI 0.82 to 1.06; studies = five; Heterogeneity: Tau² = 0.00; I² = 5%; high quality evidence). Single interventions led to marginal improvements in the number of women who delivered in health facilities (average OR 1.08, 95% CI 1.02 to 1.15; studies = 10; Heterogeneity: Tau² = 0.00; I² = 0%; high quality evidence), and in the proportion of women who had at least one ANC visit (average OR 1.68, 95% CI 1.02 to 2.79; studies = six; Heterogeneity: Tau² = 0.24; I² = 76%; moderate quality evidence). Results for ANC coverage (at least four and at least one visit) and for perinatal mortality had substantial statistical heterogeneity. Single interventions did not improve the proportion of women receiving tetanus protection (average OR 1.03, 95% CI 0.92 to 1.15; studies = 8; Heterogeneity: Tau² = 0.01; I² = 57%). No study reported onintermittent prophylactic treatment for malaria. Comparison 2: Two or more interventions versus no interventionWe found no improvements in ANC coverage of four or more visits (average OR 1.48, 95% CI 0.99 to 2.21; participants = 7840; studies = six; Heterogeneity: Tau² = 0.10; I² = 48%; low quality evidence) or pregnancy-related deaths (average OR 0.70, 95% CI 0.39 to 1.26; participants = 13,756; studies = three; Heterogeneity: Tau² = 0.00; I² = 0%; moderate quality evidence). However, combined interventions led to improvements in ANC coverage of at least one visit (average OR 1.79, 95% CI 1.47 to 2.17; studies = five; Heterogeneity: Tau² = 0.00; I² = 0%; moderate quality evidence), perinatal mortality (average OR 0.74, 95% CI 0.57 to 0.95; studies = five; Heterogeneity: Tau² = 0.06; I² = 83%; moderate quality evidence) and low birthweight (average OR 0.61, 95% CI 0.46 to 0.80; studies = two; Heterogeneity: Tau² = 0.00; I² = 0%; moderate quality evidence). Meta-analyses for both ANC coverage four or more visits and perinatal mortality had substantial statistical heterogeneity. Combined interventions improved the proportion of women who had tetanus protection (average OR 1.48, 95% CI 1.18 to 1.87; studies = 3; Heterogeneity: Tau² = 0.01; I² = 33%). No trial in this comparison reported on intermittent prophylactic treatment for malaria. Comparison 3: Two interventions compared head to head. No trials found. Comparison 4: One intervention versus a combination of interventionsThere was no difference in ANC coverage (four or more visits and at least one visit), pregnancy-related deaths, deliveries in a health facility or perinatal mortality. No trials in this comparison reported on low birthweight orintermittent prophylactic treatment of malaria. AUTHORS' CONCLUSIONS: Implications for practice - Single interventions may improve ANC coverage (at least one visit and four or more visits) and deliveries in health facilities. Combined interventions may improve ANC coverage (at least one visit), reduce perinatal mortality and reduce the occurrence of low birthweight. The effects of the interventions are unrelated to whether they are community or health system interventions. Implications for research - More details should be provided in reporting numbers of events, group totals and the ICCs used to adjust for cluster effects. Outcomes should be reported uniformly so that they are comparable to commonly-used population indicators. We recommend further cluster-RCTs of pregnant women and women in their reproductive years, using combinations of interventions and looking at outcomes that are important to pregnant women, such as maternal and perinatal morbidity and mortality, alongside the explanatory outcomes along the pathway of care: ANC coverage, the services provided during ANC and deliveries in health facilities.

Climate for evidence informed health system policymaking in Cameroon and Uganda before and after the introduction of knowledge translation platforms: a structured review of governmental policy documents.

BACKGROUND: There is a scarcity of empirical data on African country climates for evidence-informed health system policymaking (EIHSP) to backup the longstanding reputation that research evidence is not valued enough by health policymakers as an information input.Herein, we assess whether and how changes have occurred in the climate for EIHSP before and after the establishment of two Knowledge Translation Platforms housed in government institutions in Cameroon and Uganda since 2006. METHODS: We merged content analysis techniques and policy sciences analytical frameworks to guide this structured review of governmental policy documents geared at achieving health Millennium Development Goals. We combined i) a quantitative exploration of the usage statistics of research-related words and constructs, citations of types of evidence, and budgets allocated to research-related activities; and (ii) an interpretive exploration using a deductive thematic analysis approach to uncover changes in the institutions, interests, ideas, and external factors displaying the country climate for EIHSP. Descriptive statistics compared quantitative data across countries during the periods 2001-2006 and 2007-2012. RESULTS: We reviewed 54 documents, including 33 grants approved by global health initiatives. The usage statistics of research-related words and constructs showed an increase over time across countries. Varied forms of data, information, or research were instrumentally used to describe the burden and determinants of poverty and health conditions. The use of evidence syntheses to frame poverty and health problems, select strategies, or forecast the expected outcomes has remained sparse over time and across countries. The budgets for research increased over time from 28.496 to 95.467 million Euros (335%) in Cameroon and 38.064 to 58.884 million US dollars (155%) in Uganda, with most resources allocated to health sector performance monitoring and evaluation. The consistent naming of elements pertaining to the climate for EIHSP features the greater influence of external donors through policy transfer. CONCLUSIONS: This structured review of governmental policy documents illustrates the nascent conducive climate for EIHSP in Cameroon and Uganda and the persistent undervalue of evidence syntheses. Global and national health stakeholders should raise the profile of evidence syntheses (e.g., systematic reviews) as an information input when shaping policies and programmes.

Initiatives supporting evidence informed health system policymaking in Cameroon and Uganda: a comparative historical case study.

BACKGROUND: There is a scarcity of empirical data on institutions devoted to knowledge brokerage and their influence in Africa. Our objective was to describe two pioneering Knowledge Translation Platforms (KTPs) supporting evidence informed health system policymaking (EIHSP) in Cameroon and Uganda since 2006. METHODS: This comparative historical case study of Evidence Informed Policy Network (EVIPNet) Cameroon and Regional East African Community Health Policy Initiative (REACH-PI) Uganda using multiple methods comprised (i) a descriptive documentary analysis for a narrative historical account, (ii) an interpretive documentary analysis of the context, profiles, activities and outputs inventories and (iii) an evaluative survey of stakeholders exposed to evidence briefs produced and policy dialogues organized by the KTPs. RESULTS: Both initiatives benefited from the technical and scientific support from the global EVIPNet resource group. EVIPNet Cameroon secretariat operates with a multidisciplinary group of part-time researchers in a teaching hospital closely linked to the ministry of health. REACH-PI Uganda secretariat operates with a smaller team of full time staff in a public university. Financial resources were mobilized from external donors to scale up capacity building, knowledge management, and linkage and exchange activities. Between 2008 and 2012, twelve evidence briefs were produced in Cameroon and three in Uganda. In 2012, six rapid evidence syntheses in response to stakeholders' urgent needs were produced in Cameroon against 73 in Uganda between 2010 and 2012. Ten policy dialogues (seven in Cameroon and three in Uganda) informed by pre-circulated evidence briefs were well received. Both KTPs contributed to developing and testing new resources and tools for EIHSP. A network of local and global experts has created new spaces for evidence informed deliberations on priority health policy issues related to MDGs. CONCLUSION: This descriptive historical account of two KTPs housed in government institutions in Africa illustrates how the convergence of local and global factors and agents has enabled in-country efforts to support evidence-informed deliberations on priority health policy issues and lays the ground for further work to assess their influence on the climate for EIHSP and specific health policy processes.

A framework for community ownership of a text messaging programme to improve adherence to antiretroviral therapy and client-provider communication: a mixed methods study.

BACKGROUND: Mobile phone text messaging has been shown to improve adherence to antiretroviral therapy and to improve communication between patients and health care workers. It is unclear which strategies are most appropriate for scaling up text messaging programmes. We sought to investigate acceptability and readiness for ownership (community members designing, sending and receiving text messages) of a text message programme among a community of clients living with human immunodeficiency virus (HIV) in Yaoundé, Cameroon and to develop a framework for implementation. METHODS: We used the mixed-methods sequential exploratory design. In the qualitative strand we conducted 7 focus group discussions (57 participants) to elicit themes related to acceptability and readiness. In the quantitative strand we explored the generalizability of these themes in a survey of 420 clients. Qualitative and quantitative data were merged to generate meta-inferences. RESULTS: Both qualitative and quantitative strands showed high levels of acceptability and readiness despite low rates of participation in other community-led projects. In the qualitative strand, compared to the quantitative strand, more potential service users were willing to pay for a text messaging service, preferred participation of health personnel in managing the project and preferred that the project be based in the hospital rather than in the community. Some of the limitations identified to implementing a community-owned project were lack of management skills in the community, financial, technical and literacy challenges. Participants who were willing to pay were more likely to find the project acceptable and expressed positive feelings about community readiness to own a text messaging project. CONCLUSION: Community ownership of a text messaging programme is acceptable to the community of clients at the Yaoundé Central Hospital. Our framework for implementation includes components for community members who take on roles as services users (demonstrating clear benefits, allowing a trial period and ensuring high levels of confidentiality) or service providers (training in project management and securing sustainable funding). Such a project can be evaluated using participation rate, clinical outcomes, satisfaction with the service, cost and feedback from users.

Students' perspectives on research and assessment of a model template designed to guide beginners in research in a medical school in Cameroon.

BACKGROUND: Research activities for medical students and residents (trainees) are expected to serve as a foundation for the acquisition of basic research skills. Some medical schools therefore recommend research work as partial requirement for certification. However medical trainees have many difficulties concerning research, for which reason potential remedial strategies need to be constantly developed and tested. The views of medical trainees are assessed followed by their use and appraisal of a novel "self-help" tool designed for the purposes of this study with potential for improvement and a wider application. METHODS: This study was a cross-sectional survey of volunteering final-year medical students and residents of a medical school in Cameroon. RESULTS: This study surveyed the opinions of a total of 120 volunteers of which 82 (68%) were medical students. Three out of 82 (4%) medical students reported they had participated in research activities with a publication versus 10 out of 38 residents (26%). The reported difficulties in research for these trainees included referencing of material (84%), writing a research proposal (79%), searching for literature (73%) and knowledge of applicable statistical tests (72%) amongst others. All participants declared the "self-help" tool was simple to use, guided them to think and better understand their research focus. CONCLUSION: Medical trainees require much assistance on research and some "self-help" tools such as the template used in this study might be a useful adjunct to didactic lectures.

A step towards reinvigorating the COVID-19 response: an intra-action review of the WHO Regional Office for Africa Incident Management Support Team.

The WHO Regional Office for Africa (AFRO) COVID-19 Incident Management Support Team (IMST) was first established on 21 January 2020 to coordinate the response to the pandemic in line with the Emergency Response Framework and has undergone three modifications based on intra-action reviews (IAR). An IAR of the WHO AFRO COVID-19 IMST was conducted to document best practices, challenges, lessons learnt and areas for improvement from the start of 2021 to the end of the third wave in November 2021. In addition, it was designed to contribute to improving the response to COVID-19 in the Region. An IAR design as proposed by WHO, encompassing qualitative approaches to collecting critical data and information, was used. It employed mixed methods of data collection: document reviews, online surveys, focus group discussions and key informant interviews. A thematic analysis of the data focused on four thematic areas, namely operations of IMST, data and information management, human resource management and institutional framework/governance. Areas of good practice identified, included the provision of guidelines, protocols and technical expertise, resource mobilisation, logistics management, provision of regular updates, timely situation reporting, timely deployment and good coordination. Some challenges identified included a communication gap; inadequate emergency personnel; lack of scientific updates; and inadequate coordination with partners. The identified strong points/components are the pivot for informed decisions and actions for reinvigorating the future response coordination mechanism.

Doxycycline vs Hydroxychloroquine + Azithromycin in the Management of COVID-19 Patients: An Open-Label Randomized Clinical Trial in Sub-Saharan Africa (DOXYCOV).

Objective We aimed to compare the safety and efficacy of a doxycycline-based regimen against Cameroon National Standard Guidelines (hydroxychloroquine plus azithromycin) for the treatment of mild symptomatic COVID-19. Methods We conducted an open-label, randomized, non-inferiority trial in Cameroon comparing doxycycline 100 mg, twice daily for seven days versus hydroxychloroquine 400 mg daily for five days and azithromycin 500 mg at day 1 and 250 mg from day 2 through 5 in mild COVID-19 patients. Clinical recovery, biological parameters, and adverse events were assessed. The primary outcome was the proportion of clinical recovery on days 3, 10, and 30. Non-inferiority was determined by the clinical recovery rate between protocols with a 20-percentage points margin. Results One hundred and ninety-four participants underwent randomization and were treated either with doxycycline (n = 97) or hydroxychloroquine-azithromycin (n = 97). On day 3, 74/92 (80.4%) participants on doxycycline versus 77/95 (81.1%) on hydroxychloroquine-azithromycin-based protocols were asymptomatic (p = 0.91). On day 10, 88/92 (95.7%) participants on doxycycline versus 93/95 (97.9%) on hydroxychloroquine-azithromycin were asymptomatic (p = 0.44). On day 30, all participants were asymptomatic. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) polymerase chain reaction (PCR) test was negative on day 10 in 60/92 (65.2%) participants who were assigned to doxycycline and in 63/95 (66.3%) participants who were assigned to hydroxychloroquine-azithromycin. None of the participants were admitted for worsening of the disease after treatment initiation. Conclusion Doxycycline 100 mg twice daily for seven days proved to be safe and non-inferior in terms of efficacy when compared to hydroxychloroquine-azithromycin for preventing clinical worsening of mild symptomatic or asymptomatic COVID-19 and achieving virological suppression.

Trends and determining factors associated with adherence to antiretroviral therapy (ART) in Cameroon: a systematic review and analysis of the CAMPS trial.

BACKGROUND: The benefits of antiretroviral therapy (ART) cannot be experienced if they are not taken as prescribed. Yet, not all causes of non-adherence are dependent on the patient. Having to pay for medication reduces adherence rates. Non- adherence has severe public health implications which must be addressed locally and globally. This paper seeks to describe the trends in adherence rates reported in Cameroon and to investigate the determinants of adherence to ART in the Cameroon Mobile Phone SMS (CAMPS) trial. METHODS: We conducted a systematic review of electronic databases (PubMed, Google Scholar, Web of Science, CINAHL, EMBASE and PSYCINFO) for publications on adherence to ART in Cameroon (from January 1999 to May 2012) and described the trend in reported adherence rates and the factors associated with adherence. Data were extracted in duplicate. We used multivariable analyses on the baseline data for 200 participants in the CAMPS trial to determine the factors associated with adherence in four models using different measures of adherence (more than 90% or 95% on the visual analogue scale, no missed doses and a composite measure: 100% on the visual analogue scale, no missed doses and all pills taken on time). RESULTS: We identified nine studies meeting our inclusion criteria. Adherence to ART in Cameroon has risen steadily between 2000 and 2010, corresponding to reductions in the cost of medication. The factors associated with adherence to ART in Cameroon are grouped into patient, medication and disease related factors. We also identified factors related to the health system and the patient-provider relationship. In the CAMPS trial, education, side effects experienced and number of reminder methods were found to improve adherence, but only using multiple reminder methods was associated with better adherence in all the regression models (Adjusted Odds Ratio [AOR] 4.11, 95% Confidence Interval [CI] 1.89, 8.93; p<0.001; model IV). CONCLUSIONS: Reducing the cost of ART is an important aspect of ensuring adequate adherence rates. Using multiple reminder methods may have a cumulative effect on adherence to ART, but should be investigated further.

Risk factors for colonization and infection with multidrug-resistant Pseudomonas aeruginosa in intensive care unit: protocol for a systematic review and meta-analysis.

BACKGROUND: Infection with resistant Pseudomonas aeruginosa (RPA) in the intensive care unit (ICU) is known to be either endogenous or exogenous or both, but the roles of each of these contamination routes are yet to be clarified. Data regarding prevalence, risk factors, and environmental factors associated with RPA in ICU are very scanty and even when they exist, they seem to be contradictory. So, there is a strong interest in understanding both individual and environmental factors associated with RPA infection. This systematic review aims to investigate individual and environmental factors associated with the colonization and infection with RPA in ICU. METHODOLOGY: MEDLINE (Pubmed), EMBASE (OVID), the Cochrane Library (Wiley), Web of Science, CINAHL (EBSCOHost), and LILACS (BIREME) will be searched from inception onwards. Grey literature will be identified through Google Scholar and Open Grey. Two reviewers will independently screen all citations, abstracts, and full-text articles. Potential conflicts will be resolved through discussion. Methodological quality including bias will be appraised using appropriate approaches. A narrative synthesis will describe the quality and content of the epidemiological evidence. Prevalence, odds ratio, relative risk, and hazard radio with their respective 95% confidence intervals will be calculated. A meta-analysis of data extracted from eligible studies with similar populations and RPA testing will be performed. The analysis will evaluate factors influencing the estimates. A random effect model will be used to summarize effect sizes. DISCUSSION: Two contrasting hypotheses on risk factors of acquisition, colonization, and infection of RPA are being debated, especially in a context where available data are scanty or exhibit high discrepancy. Indeed, most of the reviews have been focalized on hospitalized patients, and not in ICU, and few of them address the issue of environmental factors. To fill that gap, this review will combine both analyses of individual and environmental risk factors using prevalence studies in ICU and evaluation of different methodologies. These two hypotheses will be tested and challenged and could serve as a basis for a more in-depth study to fill the methodological gaps that will be identified as part of this current review. SYSTEMATIC REVIEW REGISTRATION: This protocol has been submitted to the Prospective Register of Systematic Reviews (PROSPERO) and the registration number attributed was CRD42021233832 of 07 March 2021.

Health Insurance Ownership and Quality of Computed Tomography Requests: Experience from a Peripheral Referral Hospital in Cameroon.

BACKGROUND: Health insurance ownership facilitates access and minimizes financial hardship after utilization of healthcare services such as computed tomography (CT). Understanding the rational utilization of CT by people with health insurance can help optimize the scheme and provide baseline information for a national universal health coverage program. OBJECTIVE: To assess the relationship between health insurance ownership and the appropriateness of requests for CT in a peripheral referral hospital in Cameroon. METHODS: A survey of CT users was conducted during which information on health insurance ownership was collected and the request forms for CT assessed for appropriateness using the American College of Radiologists (ACR) Appropriateness Criteria®. RESULTS: We consecutively enrolled 372 participants of which 167 (45%) were females. The median age (range) was 52 (18-92) years. Thirty-eight out of 370 participants reported having health insurance (10.3%; 95% confidence interval (CI): 7.2%-13.4%). Twenty-nine out of 352 CT scan requests (8.2%; 95% CI: 5.3-11.0) were judged to be "inappropriate." The proportion of inappropriate scan requests was higher amongst people with health insurance compared to those without health insurance (18.4% vs. 7.0%; χ 2 = 5.8; p=0.02). In the logistic regression analysis, health insurance ownership was associated to the appropriateness of CT requests in the univariate analysis only (OR = 0.33; 95% CI: 0.13-0.84; p=0.020). CONCLUSIONS: Inappropriate requests for CT were low but nevertheless associated to health insurance ownership. The continuous sensitization and training of physicians would help minimize potential wasteful utilization of resources.

Desire for a child among HIV-infected women receiving antiretroviral therapy in Cameroon: results from the national survey EVAL (ANRS 12-116).

The majority of HIV-infected people in sub-Saharan Africa are women, many of reproductive age. Cameroon is severely hit by the AIDS epidemic and has developed a large national program for improving access to antiretroviral treatment (ART). The reproductive intentions of women living with HIV/AIDS (WLHA) who obtain access to ART in this country remain poorly documented. Our study aimed at exploring factors associated with the desire to have a child among 1433 ART-treated fertile WLHA aged <50. Analyses were based on data collected during the national cross-sectional survey EVAL (ANRS 12-116), which was conducted between September 2006 and March 2007 in 27 HIV care centers in Cameroon. Logistic regression was used to explore factors associated with women's desire to have a child, defined as reporting the wish to have a/another child. A total of 791 women (55%) reported the desire to have a child. After adjusting for age, matrimonial status, number of biological children, and sexual activity, the main factors independently associated with this desire in a multivariate analysis were having a good physical health-related quality of life (1.02 [1.01-1.03] for a one-point increment on the 12-item Short-Form Health Survey scale) and a CD4 count at ART initiation <200 cells/mm(3) (1.7 [1.2-2.4]). As a conclusion, the desire to have a child is frequent among ART-treated WLHA in Cameroon. HIV care and family planning programs should be integrated more thoroughly in order to support WLHA's reproductive choices.
