Long-Lasting Insecticidal Net Ownership and Use in Mogode Health District, Cameroon.

BACKGROUND: Cameroon is a malaria-endemic country. Many control strategies including long-lasting insecticidal nets (LLIN) have been proposed to reduce the burden of malaria. The World Health Organization aims to achieve at least 80% of people sleeping under a LLIN. This study assessed the ownership and use of LLNs in the Mogode Health District (MHD). METHODS: A community-based cross-sectional study was conducted in MHD in September 2021. Data on ownership and LLINs use were collected using structured questionnaires following the Roll Back Malaria guidelines. Univariate and multivariate analyses were performed to assess the determinants of ownership and failure to LLIN use. RESULTS:  A total of 332 households were included from eight health areas. The proportion of households with at least one LLIN was 72.0% (238). However, 232 (70.0%) reported having used LLIN (sleeping under LLIN the previous night). Household heads with higher education were six times more likely to have owned LLINs than those with no education (adjusted odds ratio (AOR)=6.8; confidence interval (CI) 1.5, 31.0, p< 0.05). Additionally, household heads between the ages of 36-50 were 4.2 times (AOR= 4.2, CI 1.3-13.8, p< 0.05) likely to fail to use LLINs in households. However, households where heads had secondary education (AOR= 0.2, CI 0.1-0.6, p< 0.05), were negatively associated with failure to use LLINs. CONCLUSION: Ownership and use of LLINs in MHD remain challenging. Therefore, this finding will contribute to improving recommendations and updating strategies such as targeted messages aimed at raising awareness of malaria during mass LLIN distribution campaigns.

Factors associated with traction alopecia in women living in Yaoundé (Cameroon).

BACKGROUND: Traction alopecia (TA) is very common in Africa but few studies on African population are available. We sought to determine factors associated with TA and measure the association between these factors and TA. METHODS: We carried out an analytical cross-sectional study in 29 hairdressing saloons in the city of Yaoundé. A questionnaire was administered and scalp exams were performed in order to look for TA and determine Marginal TA severity score if present. Participants were separated in two groups: TA group and a group without TA. RESULTS: We finally included 223 women (77 having TA and 146 without TA). The median age was 26 years for women with TA and 24 years for women without TA. The factors associated with traction alopecia we found included: age ≥ 35 years (adjusted OR = 4; p = 0.016). Hairdressing undertaken by hairdressers only (adjusted OR = 0.2; p = 0.008), the avoidance of the regular use of nets, caps and head ties (OR = 0.2; p = 0.006) and relaxing hairs once a year or less (adjusted OR = 0.2; p = 0.005) could be protective factors. As well, we found a positive correlation between age and TA severity (r = 0.235; p < 0.001). CONCLUSION: Age and some haircare practices are associated to TA occurrence in our context. Women therefore need to be educated on these various factors that could be able to cause, worsen or prevent TA.

Evaluation of the Antimicrobial Resistance Surveillance System in Sentinel Sites in Cameroon.

Background The purpose of antimicrobial resistance (AMR) surveillance is to guide clinical decision-making, characterize trends in resistance infections, and provide epidemiological data to study the impact of AMR on health and the effectiveness of control measures in health facilities and the community. To do this, regular and relevant assessments of standardized AMR surveillance systems are essential to prioritize threats and improve their performance and cost-effectiveness. The scarcity of data and the absence of a local and national strategy on the surveillance of antibiotic resistance in Sub-Saharan Africa and even more so in Cameroon do not allow an effective response to be carried out against the scourge. This gap led us to conduct a study on the evaluation of the attributes of the antibiotic resistance surveillance system in Cameroon. Methodology We conducted a descriptive, cross-sectional study over a period of one year from January to December 2021. The study was conducted in the sentinel sites of surveillance in Cameroon, namely, those of the Centre, South-West, Littoral, and North regions. Using structured questionnaires and a pre-established and pre-tested interview guide, we collected data that allowed us to assess a surveillance system's quantitative and qualitative attributes according to the CDC guidelines. Scores were assigned based on the different questionnaires to assess the attributes of the AMR surveillance system. Results Of the evaluated attributes, it appears that although the system is useful (88.9%, i.e., a score of 2), and has good completeness of data transmission (98.9%, i.e., a score of 3), it is not simple (64.3%, i.e., a score of 1), not stable (58.6%, i.e., a score of 1), not acceptable (58.6%, i.e., a score of 1), and presents poor data quality (11.05%, a score of 1). Conclusions The AMR surveillance system in Cameroon is useful with good completeness. However, many other attributes have poor performance, indicating the importance of improving the antimicrobial surveillance system.

Antibiotic consumption history of patients in a referred laboratory in Yaounde.

Background: Regulation of antibiotic prescription and consumption remains a major public health burden in low- and middle- income countries. Objective: This study aimed to describe the antibiotic consumption of patients who had a positive antibiotic culture in a reference laboratory. Methods: A retrospective descriptive study was conducted among 113 participants with positive antibiograms with a documented history of antibiotics intake at the Yaoundé University Teaching Hospital in Cameroon between January 2016 and June 2021. Data were stored and analyzed using the Census and Survey Processing System version 7.3 and Statistical Package for Social Science version 25.0. Descriptive statistics were used to estimate the indicators. Results: Of the 113 patients enrolled, 105 had a history of drug use; 56 participants (53.3%) had taken at least 2 antibiotics prior to sampling. Cephalosporins were the most consumed antibiotics (41%), followed by nitroimidazols (28.6%) and penicillins (28.6%). According to the World Health Organization classification, 55 (52.4%) took major priority antibiotics. Conclusion: We are on the alert and there is an urgent need to raise awareness among clinicians and patients alike by providing them with good clinical practice guidelines.

Outcomes of a food voucher program and factors associated with the recovery rate of children with moderate acute malnutrition in Far North Cameroon.

BACKGROUND: Research on moderate acute malnutrition (MAM) is limited, despite its high prevalence. This study examined outcomes of bi-weekly locally available foods provided via a food voucher program (FVP) on nutritional recovery [mid-upper arm circumference (MUAC) ≥ 125 mm] from MAM (defined as MUAC between 115 and 124 mm) and identified the factors associated with recovery rate in Kaélé health district, Far North Region of Cameroon. METHODS: This was a prospective study with 474 MAM children aged 6-59 months. Food voucher distribution and MUAC screening were conducted at 6 bi-weekly visits or until the child was recovered. Time to recovery was evaluated with multivariate Cox proportional regression hazard models with associations quantified using adjusted hazard ratio (aHR). The trend for MUAC, including its determinants, was examined with multivariate linear mixed effect models. RESULTS: The recovery rate was 78.3% by 6 weeks after the first food basket; 3.4% remained MAM, and 5.9% were transferred for treatment for severe acute malnutrition (SAM defined as MUAC < 115 mm). Boys were 34% more likely to recover from MAM than girls [aHR = 1.34, 95%CI (1.09, 1.67)]. Children aged 24-53 months were 30% more likely to recover than those aged 6-11 months [aHR = 1.30, 95%CI (0.99, 1.70)]. A one unit increase in weight-for-height Z-score (WHZ) was associated with 1.89-fold greater likelihood of recovery [aHR = 1.89, 95%CI (1.66, 2.14)]. Male children had on average 1.82 mm greater increase in MUAC than female children (p < 0.001). One unit increase in WHZ was associated with 3.42 mm increase in MUAC (p = 0.025). Children aged 12-23 and 24-53 months had 1.03 mm and 2.44 mm, respectively, greater increase in MUAC over the program than children aged 6-11 months (all p < 0.01). CONCLUSION: The recovery rate of MAM children treated with the FVP met the Sphere standards for targeted supplementary feeding programs (> 75%). Child's WHZ, gender and age were significant factors associated with MUAC increase and recovery from MAM in the FVP. These findings indicate the FVP approach shows promise as an effective alternative treatment for MAM with consideration of associated factors and merits further evaluation.

A comprehensive introductory course on systematic review and meta-analysis simultaneously delivered in-person and online in Cameroon.

The global increased on research outputs around health research in general and systematic reviews has not left Sub-Saharan Africa indifferent, and Cameroon in particular. Research projects have not only increased in number but also in complexity with a record proportion of systematic review projects. This indicates that there is an unprecedented need to increase knowledge and expertise on systematic reviews and meta-analyses for high-quality evidence synthesis. We plan on associating local and international expertise to strengthen the planning, conduct and reporting of systematic reviews-in and out of academia-through an integrative learning program delivered both in English and French, the official languages in the country. The general of this introductory course was to assess the feasibility of our learning program as well as the extent to which the target audience would be willing to adhere to the program. Overall, there were 148 attendees, with 51 in-person and 97 online. Forty percent of in-person attendees were university lecturers at medical schools in Cameroon. Overall, we noted that the attendees were impressed with the quality of the presentation and the general organization of this pedagogical event, and are looking forward to participating in future courses.

Hair care and epidemiological-clinical profile of traction alopecia among women in hair salons in Yaoundé, Cameroon.

Background: Hair is valued by all individuals especially women. The perception of beauty is specific to everyone. In order to fulfil their ideal beauty, women use various methods to modify their hair's appearance. Afro hair is particularly fragile, so using these methods can be particularly deleterious for black women's hair. Objectives: Describe hair care practices of women living in Yaoundé, determine the prevalence of traction alopecia (TA) and describe its clinical profile. Methods: We carried out a cross-sectional study in hairdressing saloon in Yaoundé. A questionnaire was administered and scalp exams were performed to determine Marginal TA severity score. Results: We included 223 women with a mean age of 24.9 ± 7 years. The prevalence of TA was 34.5%. Mild and moderate stages were most represented. As far as haircare is concerned, extensions were regularly used by 95.1% of participants. Wigs were regularly worn by 58.7% of participants. Chemical hair straightening was done by 87.9% of women and was performed twice to thrice a year by 43.9%. Almost 76% of women used hair straightener and hair dryer. Hair washing was done monthly by 43.8% of participants and the main cosmetic used was shampoo (75.3%). Conclusion: Traction alopecia is a very common disease in women living in Yaoundé. Extensions, wigs and shampooing are their main hair care practices.

Maternal Socio-Demographic Factors and Mother-to-Child Transmission of HIV in the North Region of Cameroon.

Background and Objective: Socio-demographic factors are important risk factors for HIV infection. Maternal socio-demographic factors associated with HIV transmission from mother to child are not well elucidated to our knowledge. This study aimed to assess the maternal socio-demographic factors associated with HIV vertical transmission. Methods: A matched case-control study was conducted among children under 15 years of age born to HIV-infected mothers; using a structured questionnaire. The study was conducted in four health facilities in the North Region of Cameroon from July 2015 to October 2016. HIV- infected children were the cases, and HIV-uninfected children were the controls. One case was matched to nearly 4 controls according to age and sex. A total of 113 HIV-infected mothers of children under 15 years of age were purposively enrolled in the study. A questionnaire was administered to mothers and socio-demographic characteristics were collected. Blood samples were collected from the mother and her child for the determination or confirmation of HIV status. Univariate and multiple logistic regressions were used to assess associations between socio-demographic variables and HIV transmission from mother to child. Results: A total of 113 HIV-infected mothers and 113 children under 15 years of age were enrolled in this study. The majority of the mothers were between the age ranges of 25 years to 34 years. Of the 113 HIV-infected mothers, 69 (61%) were Muslims, 33 (32.1%) were not educated, 88 (77.8%) were unemployed, 80 (70.9%) were married, out of which 49 (61.6%) were engaged in a monogamous union. Of the 113 children (49.6%) were female, 25 (22.1%) were HIV-infected and 88 (77.9%) were HIV-exposed uninfected. At the univariate level, mothers who achieved a primary level of education were less likely to transmit HIV to infants compared to uneducated mothers [OR=0.28; CI (0.08-0.95); p=0.04]; and widows had a higher likelihood of HIV transmission to infants compared to married mothers [OR=4.65; CI (1.26-17.20); p=0.02]. Using multiple logistic regression, the maternal primary education level [aOR=0.32; CI (0.08-0.90); p=0.03] and widowerhood [aOR=7.05; CI (1.49-33.24); p=0.01] remained highly associated with the likelihood of HIV transmission to infants. Conclusion and Global Health Implications: Uneducated mothers and widows had a higher likelihood of mother-to-child transmission of HIV. Our findings should prompt reinforcement of prevention strategies targeting uneducated women and widows.

Antibiotic consumption history of patients in a referred laboratory in Yaounde

Background. Regulation of antibiotic prescription and consumption remain a major public health burden in low- and middle-income country. This study aimed to describe the antibiotic consumption of patients who had a positive antibiotic culture in a reference laboratory. Methods. A retrospective descriptive study was conducted among 113 participants with positive antibiogram with a documented history of antibiotics intake at the Yaoundé University Teaching Hospital (YUTH) in Cameroon between January 2016 to June 2021. Data were stored and analyzed using the Census and Survey Processing System (CSPro) version 7.3 and Statistical Package for Social Science (SPSS) version 25.0. Descriptive statistic was used to estimate the indicators. Results. Of the 113 patients enrolled, 105 had a history of drug use; 56 participants (53, 3%) had taken at least 2 antibiotics prior to sampling. Cephalosporins were the most consumed antibiotics (41, 0%), followed by nitroimidazols (28, 6%) and penicillins (28,6%). According to the WHO classification, 55 (52, 4%) took the major priority antibiotics. Conclusion. We are on the alert and there is an urging need to raise awareness among clinicians and patients alike by providing them with good clinical practice guidelines.

Assessing core capacities for addressing public health emergencies of international concern at designated points of entry in cameroon during the COVID-19 Pandemic.

BACKGROUND: Points of Entry (POEs) are at the frontline for prevention, detection and response to international spread of diseases. The objective of this assessment was to ascertain the current level of existing International Health Regulations (IHR) core capacities of designated airports, ports and ground crossings in Cameroon and identify critical gaps for capacity building for prevention, early warning and response to public health threats including COVID-19. METHODS: Data were collected from April to May 2020 in 5 designated POEs: Yaounde Nsimalen International Airport (YIA), Douala international Airport (DIA), Douala Autonomous Port (DAP), Garoua-Boulai ground crossing, Kye-Ossi ground crossing which were all selected for their high volume of passenger and goods traffic. The World Health Organization (WHO) assessment tool for core capacity requirements at designated airports, ports and ground crossings was used to collect data on three technical capacities: (i) communication and coordination, (ii) Capacities at all times and (iii) capacities to respond to Public Health Emergencies of International Concern (PHEIC). RESULTS: All the investigated POEs scored below 50% of capacities in place. YIA recorded the highest percentage for all groups of capacities, coordination and communication and for core capacity at all times with a percentage of 42%, 58% and 32% respectively. For core capacity to respond to PHEIC, all the POEs recorded below 50%. The DAP and all ground crossings lacked trained personnel for inspection of conveyances. Only DIA had a public health emergency plan. There is no isolation/quarantine and transport capacity at the POEs. CONCLUSION: All POEs assessed did not meet IHR standards and need significant improvement to fulfill the IHR requirements. Unstructured communication channels between stakeholders make the implementation of IHR challenging. A coordination mechanism, with clear functions and structure, is necessary for well-coordinated response efforts to health emergencies at POEs. This assessment will serve as a baseline to inform planning and IHR implementation at designated POEs in Cameroon.

Health Security Planning: Developing the Cameroon National Action Plan for Health Security.

The health security planning process transforms recommendations from various evaluations into priority actions to strengthen countries' capacity for emergency preparedness using the One Health approach. Although the World Health Organization (WHO) has developed many tools to facilitate the planning process of a National Action Plan for Health Security (NAPHS) across the various components, a series of multisectoral workshops is still needed to complete the process. In this article, we report on the process of developing Cameroon's NAPHS and propose an innovative solution to improve the process. The NAPHS development process was conducted from May to December 2018. The WHO NAPHS framework, adapted to the local context, guided the process. The WHO planning matrix was used to plan activities and the WHO NAPHS costing tool was used to facilitate the costing exercise. A total of 84 Joint External Evaluation recommendations were translated into activities included in Cameroon's NAPHS. Among these activities, the majority (56%) were of medium priority. The total cost of a 5-year NAPHS was US$87,668,356, with almost half (49%) of the budget allocated to activities in the "Prevent" category and more than a third (35%) allocated to the "Detect" category. The top 3 cost drivers were immunization (22%), the national laboratory system (21%), and antimicrobial resistance (16%). The NAPHS informed policymakers of planned activities and funding needs to fast-track the development of health security capacities. Running gaps in funding will be addressed during a resource mapping exercise. To improve the overall planning process, a web-based support solution, where stakeholders select from a menu of recommendations from the Joint External Evaluation to develop a NAPHS, should be developed to improve the NAPHS development process.

Challenges, best practices, and lessons learned from oral cholera mass vaccination campaign in urban Cameroon during the COVID-19 era.

BACKGROUND: Since 1971, Cameroon has been facing an ever-growing series of cholera epidemics; despite all the efforts made by the government to address this substantial public health problem. In 2020, in addition to the COVID-19 pandemic, Cameroon recorded a high cholera case fatality rate of 5.3% following epidemics noted in the South, Littoral, and South-West regions which is far higher than the 1% World Health Organization acceptable rate. METHODOLOGY/PRINCIPAL FINDINGS: The Ministry of Public Health organized a reactive vaccination campaign against cholera to address the high mortality rate in the affected health districts. The first round was in August 2020 and the second in March 2021. We conducted a cross-sectional study and reviewed this vaccination campaign's challenges, best practices, and lessons. The vaccination coverage for the two doses of the oral cholera vaccine was 80.4%, with a refusal rate as high as 67%. People 20 years and above recorded the lowest vaccination coverage. The main challenge was misinformation about the cholera vaccine. The best practice was thorough population sensitization through community actors. CONCLUSION: Proper communication will always brave the odds of hesitancy and favor mass population vaccination to thwart hesitancy and consolidate herd immunity.

Stillbirths in Cameroon: an analysis of the 1998-2011 demographic and health surveys.

BACKGROUND: Many countries, including Cameroon, have found it challenging to estimate stillbirths, as there are limited available reports accurately. This analysis aimed to assess stillbirth rates and identify risk factors for stillbirth in Cameroon using successive Demographic and Health Survey data. METHODS: We conducted a cross-sectional analysis of data collected during the Demographic and Health Surveys of 1998, 2004, and 2011. Data were analyzed using SPSS 20.0. Logistic regressions were used to identify factors associated with stillbirth through odds ratios (ORs) at 95% confidence intervals (CI). Results were considered statistically significant at p-value less than 0.05. RESULTS: The crude stillbirth rate was 21.4 per 1,000 births in 2004 and 24 per 1,000 births in 2011, with respective standard errors of 1.8 and 1.3. The stillbirth rate increased with the mother's age (p < 0.001). The stillbirth rate reduction was prolonged between 1998 and 2011, with an annual reduction rate of 1.6%. The study observed that residing in rural areas, low socioeconomic status, and low level of education were risk factors associated with stillbirths. CONCLUSION: Cameroon's stillbirth rate remains very high, with a slow reduction rate over the last 20 years. Although some efforts are ongoing, there is still a long way forward to bend the curve for stillbirths in Cameroon; supplementary strategies must be designed and implemented, especially among rural women, the poor, and the less educated.

The first 30 days of COVID-19 vaccination in Cameroon: achievements, challenges, and lessons learned.

Introduction: Cameroon's national vaccination campaign was launched on April 12, 2021, amid a nationwide outbreak of COVID-19 with two types of vaccines. This study provides preliminary evidence to assess early outputs of the COVID-19 vaccination response strategy implementation. Methods: a cross-sectional study was conducted from April 12, 2021, to May 11, 2021, and data on COVID-19 vaccination were reviewed from the Ministry of Public Health database. Descriptive statistical analyses were conducted. Results: thirty days after the introduction of COVID-19 vaccines, just about five percent of the target population was vaccinated. Women represented one-third of the people vaccinated regardless of age and health conditions. Although AEFI reported were minor and scanty with both vaccines, most of the vaccinated did not come back for their second dose. There was a need to build confidence among eligible beneficiaries to expand the benefits of vaccination to control the current pandemic. Conclusion: the country was still far below the target, which was worrisome given that vaccine uptake was slow. Also, 391 200 doses of the Covishield were at risk of expiration in August 2021. This study offers insights into those early efforts contributing to significant discussions about the approaches to improve service delivery and vaccine uptake.

Validation of lipid profile measurement methods and establishment of reference values in a sub-Saharan African population.

Validated reference values and procedures are needed to ensure optimal diagnosis of dyslipidemia in sub-Saharan Africa. We aimed to validate an analysis method and establish reference intervals of lipid profile parameters in Cameroonians using this method. On a cross-sectional study conducted from November 2019 to August 2020 in Yaoundé, we have analyzed blood samples with Cobas® 6000. We subscribed to ASQUALAB's External Quality Assessments (EQA) and Outsourced Internal Quality Controls (IQC). Reproducibility, repeatability, correctness accuracy and uncertainty were evaluated using IQC. Consenting adult participants were conveniently sampled, excluding those with any condition that may affect lipid profile. Descriptive statistics were reported accordingly, agreement was assessed with Bland-Altman analysis, and reference intervals were defined according to CLSI and IFCC recommendations. The coefficients of variation for repeatability, reproducibility, and correctness bias ranged between 0.6% and 6%, with all values within the normal range. Expanded uncertainty of total cholesterol, HDL and triglycerides measurements were, respectively, 0.45, 0.24 and 0.18. We included 422 participants with a mean age of 30.2 (10.9) years and 248 (58.8%) females. Reference intervals for total cholesterol, HDL, triglycerides and LDL were, respectively, 2.94-6.02 mmol/L, 0.90-2.06 mmol/L, 0.35-1.36 mmol/L, 1.37-4.13 mmol/L. These intervals were similar between sex and ethnic groups, but lower in younger participants. Lipid profile measurement with Cobas® 6000 is a reliable and accurate analysis in our context. Specific reference intervals must be used in African population, with further studies need for different age subgroups.

Implementation of an Africa-specific donor health questionnaire for human immunodeficiency virus risk screening.

BACKGROUND AND OBJECTIVES: We had previously developed an Africa-specific donor health questionnaire (ASDHQ) based on local risk factors and designed a scoring scheme. This study assessed the performance of a new donor health questionnaire by comparing the human immunodeficiency virus (HIV) status in accepted versus deferred donors by ASDHQ and comparing the rate of risk deferrals with historical data. MATERIALS AND METHODS: Data were collected during a cross-sectional study conducted over 15 months at three referral-hospital-based blood services in Cameroon. ASDHQ was administered to blood donors aged 18-65 years in the same screening conditions as the routine questionnaire. The main outcomes of the study were ASDHQ sensitivity and specificity with regard to HIV laboratory testing as well as donor deferral rates for each of the routine screening algorithms and for ASDHQ. RESULTS: Overall, 71/11,120 (0.6%) were confirmed as HIV positive. The mean ASDHQ score was 95.80 ± 4.4 in HIV-negative donors and 94.80 ± 4.4 in HIV-positive donors (p = 0.05). The optimal cut-off provided by the receiver operating characteristic (ROC) curve for the best performance of ASDHQ was 95.04. Using this optimal cut-off, the ASDHQ sensitivity and specificity were 57% and 53%, respectively (area under curve = 0.58 [0.51, 0.64], p = 0.028). Using ASDHQ, the HIV prevalence was 0.7% in deferred donors and 0.6% in accepted donors. CONCLUSION: ASDHQ might be efficient only in specific conditions that maximize truthful donor responses, requiring each blood service to create an environment of trust and transparency to increase donor compliance and improve the accuracy of the questionnaire.

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.

Trends in serological markers of transfusion transmissible infections in blood donations at the Bamenda Hospital-based Blood Service, Cameroon.

OBJECTIVES: The rate and trend of transfusion transmissible infections (TTIs) in blood donations from 2012 to 2017 at the Bamenda Regional Hospital Blood Service (BRHBS), Cameroon was assessed. MATERIALS AND METHODS: A six-year retrospective study was conducted by reviewing the records of donors. Blood was screened for HIV, hepatitis B, hepatitis C and syphilis. Data was analyzed using IBM SPSS Statistics version 21. Differences in seropositivity rates for the four TTIs were analyzed using Chi2 test or Fisher's exact test where appropriate. Associations between sociodemographic characteristics and the TTIs markers were assessed using multiple logistic regression analysis. RESULTS: A total of 12,115 blood donations was included in the study and of these, the overall seropositivity rate of the four conventional TTIs markers was 10.5% (n=1,273). Of the seropositive cases, 23.8% (n=303) showed reactivity with at least two of the markers combined. When the markers were assessed individually, HBsAg recorded the highest seropositivity rate (4.7%), followed by anti-HIV and anti-syphilis (2.2%), and then by anti-HCV (1.7%). A significant decrease in the trend of the combined serological markers, HBsAg and anti-syphilis was observed over the years (P≤0.05). CONCLUSION: There is a decrease in seropositivity rates of TTIs markers in this blood service. Ongoing efforts toward the prevention of these infections is encouraged and should be intensified to improve blood safety.

Decrease in Hospitalizations and Increase in Deaths during the Covid-19 Epidemic in a Pediatric Hospital, Yaounde-Cameroon and Prediction for the Coming Months.

BACKGROUND: The COVID-19 pandemic reached Cameroon in March, 2020. The aim of this study was to unveil the consequences of this pandemic on hospitalizations and on mortality in a pediatric hospital. Methods: A descriptive and retrospective cross-sectional study was carried out using hospitalization and death statistics collected from a pediatric hospital. We compared the data before and after the pandemic and made predictions for the next 12 months. Results: A drastic drop in hospitalizations was noted coinciding with the partial lockdown in Cameroon. Paradoxically, at the same time, the number of deaths per month doubled though the causes remained the same as in the past. Conclusion: The COVID-19 pandemic was marked by drop in hospitalizations and paradoxically, an increase in child mortality. These deaths were probably due not to SARS-Cov-2 infection, but rather due to the usual illnesses whose management was delayed, a probable consequence of the confinement.

Factors associated with the performance of routine health information system in Yaoundé-Cameroon: a cross-sectional survey.

BACKGROUND: Routine Health Information Systems (RHIS) of low-income countries function below the globally expected standard, characterised by the production and use of poor-quality data, or the non-use of good quality data for informed decision making. This has negatively influenced the health service delivery and uptake. This study focuses on identifying the factors associated with the performance of RHIS of the health facilities (HF) in Yaoundé, so as to guide targeted RHIS strengthening. METHODS: A HF-based cross-sectional study in the 6 health districts (HDs) of Yaoundé was conducted. HFs were chosen using stratified sampling with probability proportional to size per HD. Data were collected, entered into Microsoft Excel 2013 and analysed with IBM- SPSS version 25. Consistency of the questionnaire was measured using Cronbach's alpha coefficient. Pearson's chi-square (and Fisher exact where relevant) tests were used to establish relationships between qualitative variables. Associations were further quantified using unadjusted Odd ratio (OR) for univariable analysis and adjusted odds ratio (aOR) for multivariable analysis with 95% confidence interval (CI). A p-value of less than 0.05 was considered statistically significant. RESULTS: Of 111 selected HFs; 16 (14.4%) were public and 95 (85.6%) private. Respondents aged 24-60 years with an average of 38.3 ± 9.3 years; 58 (52.3%) males and 53(47.7%) females. Cronbach's alpha was 0.96 (95%CI: 0.95-0.98, p < 0.001), proving that the questionnaire was reliable in measuring RHIS performances. At univariable level, the following factors were positively associated with good performances: supportive supervision (OR = 3.03 (1.1, 8.3); p = 0.02), receiving feedback from hierarchy (OR = 3.6 (0.99, 13.2); p = 0.05), having received training on health information (OR = 5.0 (1.6, 16.0); p = 0.003), and presence of a performance evaluation plan (OR = 3.3 (1.4, 8.2), p = 0.007). At multivariable level, the only significantly associated factor was having received training on health information (aOR = 3.3 (1.01, 11.1), p = 0.04). CONCLUSION: Training of health staff in the RHIS favors RHIS good performance. Hence, emphasis should be laid on training and empowering staff, frequent and regular RHIS supervision, and frequent and regular feedback, for an efficient RHIS strengthening in Yaoundé.
