ABSTRACT

The misuse of antibiotics in livestock contributes to the emergence of antibiotic resistant bacteria. The development of antibiotic resistance in bacteria of animal origin is of public health concern since drug resistant pathogens in animals can spread to humans. Several countries have therefore introduced regulations to restrict the use of antibiotics in livestock. Namibia was the first African country to ban the use of antibiotics as growth promoters and restrict the use of antibiotics to the treatment of bacterial diseases with a prescription from a veterinarian. However, there are limited studies on antibiotic stewardship among farmers in the country. The aim of this study was to determine the antibiotic awareness and usage of cattle farmers in Oshikoto region Namibia. A questionnaire on antibiotic knowledge, attitudes and practices (KAP) was administered to 274 randomly selected cattle farmers in Namibia. To calculate the KAP scores, one mark was awarded for each correct answer and zero was awarded for incorrect or unsure responses. Respondents having ≥ 50% correct answers were considered as having good KAP scores. The KAP score ranged from 8 to 73%. Forty-three per cent of the respondents had good KAP scores. Good KAP was associated with age, farm type and education status. Semi-commercial/commercial farmers had significantly better KAP than post and homestead farmers. The findings of this study indicate that there is a need to improve antibiotic usage and resistance education programmes in order to promote rational antibiotic usage.

ABSTRACT

In Namibia, the Value Added Tax (VAT) Amendment Act 2022, which reclassified the supply of sanitary pads as zero-rated, has significant implications for adolescent girls' menstrual health and education. The policy change responds to the need to address period poverty by making essential menstrual products more accessible and affordable. Menstruation is a normal biological process, and access to sanitary products is a human right. Taxing menstrual products reinforces gender inequalities and raises concerns about the basic rights and dignity of women and girls. The VAT-free policy creates a system to reduce the financial burden on girls and women, making it easier for them to manage their periods safely and with dignity. It has the potential to reduce absenteeism from school, ultimately improving educational outcomes for adolescent girls. However, VAT exemptions alone are insufficient to address the broader accessibility issues that impact menstrual hygiene. Evidence-based policies that focus on the availability and affordability of a full range of sanitary products, in conjunction with regulatory mechanisms for price and quality control, are necessary to ensure that menstrual products are safe, affordable, and accessible for all.

ABSTRACT

Workplace-based evaluation is one of the most important, but challenging aspects of medical education. The aim was to improve the assessment of the rural community-based clinical training for undergraduate 3rd and 4th year family medicine students at the University of Namibia (UNAM) and implement a paperless process. An online module was developed on the Moodle platform to include a study guide, an electronic portfolio, and electronic resources (e-books and apps) to replace the current paper version of the logbook. We explored local resources by engaging with students and clinical trainers on how to best conduct the initial implementation. Engagement also entailed motivating students to actively participate in the implementation process. All 3rd and 4th year community-based education end service (COBES) students are now submitting proof of clinical learning electronically with the use of their phones in their online portfolio and using online resources. In addition, students in the practical family medicine module that has been introduced in the 6th year since 2023 are now also using an electronic portfolio and these assessment tools.Contribution: Overall feedback from students and supervisors indicates a positive atmosphere of learning and constructive feedback on performance from all team members, hopefully improving work-based assessments and ultimately patient care. More members of the primary health care team were involved and the carbon footprint has also been decreased.

ABSTRACT

BACKGROUND:  Despite the efforts of Namibia's Ministry of Health and Social Services to build maternity waiting homes (MWHs), few pregnant women make use of them. Long distances among the general population in Namibia limit the utilisation of MWHs. Little research has investigated what factors are limiting the use of these facilities despite the urgent need for them. The aim of this study thus was to explore and describe the perspectives of pregnant women on the utilisation of the MWHs near Onandjokwe Lutheran Hospital in Oshikoto Region. METHODS:  A qualitative, exploratory, descriptive and contextual design was employed. The accessible population in this study comprised 18 participants who were selected for the study using a purposive sampling technique. RESULTS:  Participants reported numerous barriers to visiting MWHs in Namibia, including an inadequate number of rooms, theft, food scarcity and the effects of poverty on the living conditions of the MWH users. Enablers visiting MWHs included the safe delivery of babies by skilled staff, reduced transport costs, access to timely management of labour complications and affordable accommodation. CONCLUSION:  The study revealed that a number of barriers must be overcome before the desired number of women take advantage of MWHs. Multiple factors act as constraints to their use, including inadequate number of rooms, theft, food scarcity and the long distance between patients' homes and MWH services.Contribution: The study's findings can be used to develop targeted interventions and strategies that can be used by MWH providers to address the identified barriers.

ABSTRACT

The Namib Desert is a hyperarid coastal desert where fog is a major moisture source. We hypothesized that the fog-harvesting grass Stipagrostis sabulicola establishes an important ecological niche, termed the "Fog-Plant-Oases" (FPOs), and serves as the primary carbon source for the invertebrate community. To determine this, we measured the natural variations of the stable carbon and nitrogen isotopes (δ13C and δ15N) of invertebrates as well as that of plant biomass and belowground detritus and estimated the contributions of the fog plants in their diets. Our findings revealed a complex trophic structure and demonstrated that S. sabulicola fuels carbon flow from lower to higher trophic levels in the aboveground food web. The distinct δ13C values of bacterial- and fungal-feeding nematodes indicated however the separation of the aboveground niche, which is primarily sustained by S. sabulicola, from the belowground niche, where wind-blown sediments may serve as the main energy source for the soil biota. Our findings further accentuate the critical role of S. sabulicola FPOs in establishing complex trophic dynamics and a distinctive food web within the hyperarid Namib dunes.

ABSTRACT

Type I hypolithons are microbial communities dominated by Cyanobacteria. They adhere to the underside of semi-translucent rocks in desert pavements, providing them with a refuge from the harsh abiotic stresses found on the desert soil surface. Despite their crucial role in soil nutrient cycling, our understanding of their growth rates and community development pathways remains limited. This study aimed to quantify the dynamics of hypolithon formation in the pavements of the Namib Desert. We established replicate arrays of sterile rock tiles with varying light transmission in two areas of the Namib Desert, each with different annual precipitation regimes. These were sampled annually over 7 years, and the samples were analysed using eDNA extraction and 16S rRNA gene amplicon sequencing. Our findings revealed that in the zone with higher precipitation, hypolithon formation became evident in semi-translucent rocks 3 years after the arrays were set up. This coincided with a Cyanobacterial 'bloom' in the adherent microbial community in the third year. In contrast, no visible hypolithon formation was observed at the array set up in the hyper-arid zone. This study provides the first quantitative evidence of the kinetics of hypolithon development in hot desert environments, suggesting that development rates are strongly influenced by precipitation regimes.

ABSTRACT

Background: Adolescents living with HIV (ALHIV) lag behind younger children and adults in the achievement of HIV care and treatment targets for HIV epidemic control. Treatment outcomes for adolescents may be influenced by their experiences with the support provided in HIV programs. We report on the experiences of virally unsuppressed adolescents and their caregivers with the current support in primary healthcare settings in Namibia. Methods: A qualitative descriptive and exploratory study was conducted in 13 public primary healthcare facilities in Windhoek, Namibia. A total of 25 in-depth interviews were conducted with unsuppressed adolescents (n = 14) and their caregivers (n = 11) between August and September 2023. The audio-recorded interviews were transcribed verbatim, and uploaded into ATLAS.ti software, and subjected to thematic content analysis. Findings: Three main support domains for the unsuppressed adolescents emerged from our analysis, namely: psychosocial, clinical and care, and socioeconomic support. The psychosocial support was delivered through peer support (teen clubs and treatment supporters) and enhanced adherence counselling mostly. The clinical and care support included implementing adolescent-friendly HIV services, differentiated service delivery approaches, and caregivers and healthcare worker care support for improved ART adherence, clinic attendance and continuous engagement in care. Socioeconomic support was provided for nutritional support, transport to access clinics, and school supplies, as well as income-generating projects. Conclusion: Psychosocial, clinical and care, and socioeconomic support are key elements in addressing the needs of adolescents challenged with achieving viral suppression. Health systems may benefit from whole-of-society and whole-of-government approaches to meet the needs of ALHIV that are beyond the scope of health service delivery such as nutritional, education and socioeconomic influences on both the health and well-being of ALHIV.

ABSTRACT

BACKGROUND:  Globally, enrolled nurses (ENs) are embarking on an educational journey to become registered nurses (RNs) in order to enhance their knowledge and career opportunities. However, their aspiration is not without challenges. In Namibia, the experiences of these nurses have not been extensively researched. OBJECTIVES:  This study aims to explore and describe the experiences and challenges of ENs undertaking a Bachelor of Nursing Science at the University of Namibia. METHOD:  A qualitative, exploratory, descriptive and contextual research strategy was followed as the basis of conducting the study. A sample of 15 nursing students was purposively selected from the target population of 73 nursing students. This sample size was determined by the saturation of data as reflected in repeating themes. The collected data were analysed thematically using an inductive approach. RESULTS:  Three main themes subsequently emerged from the study: ENs' positive experiences advancing in the Bachelor of Nursing Science (BNSc) programme; nurses' negative experiences advancing in the BNSc programme; and recommendations to ensure effective advancement in the BNSc programmeConclusion: The findings of this study revealed that ENs positively experience becoming a RN when it comes to self-development; however, they have negative experiences such as not receiving exemptions for prior learning and having to learn a new curriculum.Contribution: These findings may be used by the Faculty of Health Sciences, School of Nursing and Public Health management in order to develop targeted interventions and ongoing strategies during their curriculum review cycles to ensure positive student experiences and success within the programme.

ABSTRACT

The factors influencing the adoption and implementation of CE in developing countries are not yet fully examined. By focusing on the Namibian mining sector, this study highlights the perspectives of local stakeholders on CE adoption in a developing country. The mine managers recognized that waste is problematic and that CE practices are beneficial for mining companies and Namibia at large. Our findings also indicated that stronger academic institutions providing CE training and helping develop CE solutions, public awareness campaigns, financial support for CE practices, cooperation among industry stakeholders, and clear CE policy would all help drive the implementation of CE.

ABSTRACT

Substantial evidence indicates that medical mistrust, resulting from experiences with discrimination and marginalisation, is a determinant of health disparities in minority populations. However, this research is largely limited to the US and other industrialised countries. To broaden our understanding of the role of medical mistrust on health-care decision making, we conducted a study on healthcare experiences and perceptions in a rural, underserved indigenous community in northwest Namibia (n = 86). Mixing semi-structured interview questions with the medical mistrust index (MMI), we aim to determine the relevance of the MMI in a non-industrialised population and compare index scores with reports of healthcare experiences. We find that medical mistrust is a salient concept in this community, mapping onto negative healthcare experiences and perceptions of discrimination. Reported healthcare experiences indicate that perceived incompetence, maltreatment and discrimination drive mistrust of medical personnel. However, reporting of recent healthcare experiences are generally positive. Our results indicate that the concept of medical mistrust can be usefully applied to communities in the Global South. These populations, like minority communities in the US, translate experiences of discrimination and marginalisation into medical mistrust. Understanding these processes can help address health disparities and aid in effective public health outreach in underserved populations.

ABSTRACT

BACKGROUND: Sickle cell disease (SCD), a noncommunicable disease, has the greatest burden in sub-Saharan Africa. The majority of children (50-90%) with SCD die before their 5th birthday, with approximately 150,000-300,000 annual SCD child deaths in Africa. In developed countries, newborn screening (NBS) has been shown to improve the survival of children with sickle cell disease, with under5 childhood mortality reduced tenfold due to interventions performed before the development of complications. Point -of-care tests have been developed for resource limited settings to expand NBS. The aim of this study was to determine the birth prevalence of sickle cell disease in Namibia using the HemoTypeSC™ point-of-care test. METHODS: A cross-sectional descriptive study was carried out at Rundu Intermediate Hospital in the Kavango East Region. Two hundred and two (202) well newborns within 72 h of birth were recruited for the study from 22 February to the 23th March 2023. Descriptive statistics were used to compute the haemoglobin types of the study participants. RESULTS: The majority of the participants (n = 105, 52%) were females, and (n = 97,48%) were males. The median age of the participants was 23 h (Q1, Q3; 11; 33),) with an age range of 2-98 h. Sickle cell trait was present in 9.4% of the screened newborns, no homozygous disease was detected, and 90.6% had Hb AA. CONCLUSIONS: This study is the first to measure HbS gene carriage at birth using HemotypeSC point-of-care testing in Namibia. There was a moderate prevalence of sickle cell traits but no SCD. This baseline study may provide the foundation for larger epidemiological surveys to map HbS gene carriage in Namibia to provide evidence for policy makers to fashion appropriate SCD newborn screening services.

ABSTRACT

Introduction: quality data is a prerequisite for timely decision-making and measuring health outcomes in public health settings. Comorbidities such as cardiovascular diseases (CVDs) among people living with HIV (PLHIV), require a robust system that ensures credible data at all data-producing levels. The study at determining the level of availability and completeness of CVDs risk factors data of PLHIV. Methods: a quantitative study was conducted to extract CVDs risk factors data retrospectively from 529 patient care booklets (PCBs) between 2004 and 2017. The analysis was done with the Statistical Package for Social Sciences (SPSS) version 25. Pearson Chi-Square was used to test for associations. The level of significance was at p ≤ 0.05. Results: the study revealed that 72.8% of patients are at risk of CVDs due to incomplete demographics (73.72%) and other systemic data (41.18%). A significant association was found (Pearson Chi-Square test 19.907; p-value of 0.001) between average visits per year, accurate data recording, and active status of the patient. Lost to follow-up (15%) and true retention (27.2%) was significantly associated with the last Antiretroviral Therapy (ART) status of a patient (Pearson Chi-Square test 87.754; p-value of 0.001). Conclusion: the study that despite concerted efforts to improve data quality, the availability and completeness of data remain unsatisfactory. Lack of harmonised data screening and analysis efforts for CVDs risk factors is found to be a significant risk factor in ensuring integrated routine measuring of CVDs health outcomes for PLHIV.

ABSTRACT

BACKGROUND: Changes in lifestyle and dietary habits that hunter-gatherer populations have undergone in recent decades have often led to rising obesity rates with disastrous consequences for their health. OBJECTIVES: The associations between dietary habits and weight status were studied in 238 "Ju/'hoansi" San (93 women and 145 men) aged between 18 and 65 years in northern Namibia in 1987. Weight status was estimated based on the World Health Organization body mass index (BMI) categories, and dietary habits were recorded using food recall methods. Anthropometrics and weight status were compared with those of a sex- and age-matched sample of "Ju/'hoansi" San people collected by Nancy Howell in 1968/69. RESULTS: Body weight had increased significantly among "Ju/'hoansi" San people from 1968/69 to 1987. The number of underweight people decreased from 1968/69 to 1987. In 1987, most participants (60.9%) were of normal weight. Overweight was found in 1.3% of the women, but not among men. No participants were obese. Less than 4% of the women and less than 2% of the men consumed exclusively traditional hunter-gatherer food. Westernized food products were significantly (p < 0.001) more common among men and younger people. Dietary patterns were significantly associated with weight status. The less traditional the diet, the higher the BMI (p < 0.001). CONCLUSION: The transition to domestic agricultural and westernized foods was positively associated with increasing BMI. Overweight, however, was still an extremely rare condition in this population in 1987.

ABSTRACT

Regular physical activity (PA) is known to promote the physical and mental health of children and adolescents and further prevent the development of health problems in adulthood. Information on body composition and PA is crucial for health promotion strategies and for epidemiological studies informing policies. However, there is limited data on the association between body composition and PA in Namibia. This dearth of published data is a significant shortcoming in the development of strategies and policies to promote PA in Namibia. Therefore, this cross-sectional study was conducted to determine the association between PA as a dependent variable and independent variables such as high blood pressure and body fatness as measured by different methods (gold standard deuterium dilution, body mass index, mid upper arm circumference, and waist circumference). The study included 206 healthy adolescent girls aged 13-19 years and 207 young adult females aged 20-40 years from Windhoek, Namibia. PA was measured using the PACE+ questionnaire in adolescents, and the GPAQ questionnaire was used for adults. In adolescents, only 33% of the participants met the recommended guidelines for PA, compared to only 2% for adults. Nevertheless, the study found no statistically significant association between PA and blood pressure indices (p-value < 0.05) among adolescents and adults. However, there was a significant association between PA and high body fatness (p-value < 0.001) and waist circumference (p-value = 0.014) in adolescents. Among adults, PA was significantly related to waist circumference only. In conclusion, failure to meet recommended PA guidelines is strongly associated with abdominal obesity and high body fatness. The knowledge gained from this study may be used by policymakers in the development of strategic policies and interventions aimed at promoting PA as a public priority and improving health outcomes.

ABSTRACT

The increasing pressure on freshwater systems due to intensive anthropogenic use is a big challenge in central-northern Namibia and its catchment areas, the Kunene and the Kavango Rivers, and the Cuvelai-Etosha Basin, that provide water for more than 1 million people. So far, there is no comprehensive knowledge about the ecological status and only few knowledge about the water quality. Therefore, it is crucial to learn about the state of the ecosystem and the ecological effects of pollutants to ensure the safe use of these resources. The surface waters of the three systems were sampled, and three bioassays were applied on three trophic levels: algae, daphnia, and zebrafish embryos. Additionally, in vitro assays were performed to analyze mutagenicity (Ames fluctuation), dioxin-like potential (micro-EROD), and estrogenicity (YES) by mechanism-specific effects. The results show that acute toxicity to fish embryos and daphnia has mainly been detected at all sites in the three catchment areas. The systems differ significantly from each other, with the sites in the Iishana system showing the highest acute toxicity. At the cellular level, only weak effects were identified, although these were stronger in the Iishana system than in the two perennial systems. Algae growth was not inhibited, and no cytotoxic effects could be detected in any of the samples. Mutagenic effects and an estrogenic potential were detected at three sites in the Iishana system. These findings are critical in water resource management as the effects can adversely impact the health of aquatic ecosystems and the organisms within them.

ABSTRACT

During a 2021 parasitological survey of birds in the Nyae Nyae-Khaudum Dispersal Area (Kavango-Zambezi Transfrontier Conservation Area, Namibia), we collected 9 specimens of Dendritobilharzia pulverulenta (Braun, 1901) Skrjabin, 1924 infecting the blood (heart lumen) of a white-backed duck, Thalassornis leuconotus (Eyton, 1838) (Anseriformes: Anatidae), and a fulvous whistling duck, Dendrocygna bicolor (Vieillot, 1816) (Anatidae). These flukes were fixed for morphology and preserved for DNA extraction. We assigned our specimens to DendritobilharziaSkrjabin and Zakharow, 1920 because they were strongly dorso-ventrally flattened in both sexes and had an intestinal cyclocoel with a zig-zag common cecum with lateral dendritic ramifications, numerous testes posterior to the cyclocoel and flanking the dendritic ramifications, and a tightly compacted convoluted ovary as well as lacking an oral sucker, ventral sucker, and gynaecophoric canal. Further, our specimens were morphologically identical to previously published descriptions of D. pulverulenta. Sequences of the 28S from our specimens were nearly identical to those identified as D. pulverulenta from North America (New Mexico), and our 28S phylogenetic analysis recovered D. pulverulenta within a polytomy of other Gigantobilharziinae spp. The CO1 phylogenetic analysis recovered a monophyletic Dendritobilharzia and, with low taxon sampling, a monophyletic Gigantobilharzia. This is the first record of a species of Dendritobilharzia infecting these ducks as well as the first record of an adult Dendritobilharzia from sub-Saharan Africa. The original description of adult D. pulverulenta (type locality: northern Sudan) was based on 2 males only, and hence the present study is the first description of female D. pulverulenta from Africa (the continent of the type locality). We reassign 2 Gigantobilharziinae spp. based on morphology and nucleotide evidence: Gigantobilharzia ensenadense (Lorenti, Brant, Gilardoni, Diaz, and Cremonte, 2022) Dutton and Bullard, n. comb., and Gigantobilharzia patagonense (Lorenti, Brant, Gilardoni, Diaz, and Cremonte, 2022) Dutton and Bullard, n. comb. We also comment on several avian schistosome sequences whose identities need confirmation or that likely have been misidentified.

ABSTRACT

BACKGROUND: Estimating the size of key populations, including female sex workers (FSW) and men who have sex with men (MSM), can inform planning and resource allocation for HIV programs at local and national levels. In geographic areas where direct population size estimates (PSEs) for key populations have not been collected, small area estimation (SAE) can help fill in gaps using supplemental data sources known as auxiliary data. However, routinely collected program data have not historically been used as auxiliary data to generate subnational estimates for key populations, including in Namibia. OBJECTIVE: To systematically generate regional size estimates for FSW and MSM in Namibia, we used a consensus-informed estimation approach with local stakeholders that included the integration of routinely collected HIV program data provided by key populations' HIV service providers. METHODS: We used quarterly program data reported by key population implementing partners, including counts of the number of individuals accessing HIV services over time, to weight existing PSEs collected through bio-behavioral surveys using a Bayesian triangulation approach. SAEs were generated through simple imputation, stratified imputation, and multivariable Poisson regression models. We selected final estimates using an iterative qualitative ranking process with local key population implementing partners. RESULTS: Extrapolated national estimates for FSW ranged from 4777 to 13,148 across Namibia, comprising 1.5% to 3.6% of female individuals aged between 15 and 49 years. For MSM, estimates ranged from 4611 to 10,171, comprising 0.7% to 1.5% of male individuals aged between 15 and 49 years. After the inclusion of program data as priors, the estimated proportion of FSW derived from simple imputation increased from 1.9% to 2.8%, and the proportion of MSM decreased from 1.5% to 0.75%. When stratified imputation was implemented using HIV prevalence to inform strata, the inclusion of program data increased the proportion of FSW from 2.6% to 4.0% in regions with high prevalence and decreased the proportion from 1.4% to 1.2% in regions with low prevalence. When population density was used to inform strata, the inclusion of program data also increased the proportion of FSW in high-density regions (from 1.1% to 3.4%) and decreased the proportion of MSM in all regions. CONCLUSIONS: Using SAE approaches, we combined epidemiologic and program data to generate subnational size estimates for key populations in Namibia. Overall, estimates were highly sensitive to the inclusion of program data. Program data represent a supplemental source of information that can be used to align PSEs with real-world HIV programs, particularly in regions where population-based data collection methods are challenging to implement. Future work is needed to determine how best to include and validate program data in target settings and in key population size estimation studies, ultimately bridging research with practice to support a more comprehensive HIV response.

ABSTRACT

Despite global agreements on adolescents' sexual and reproductive health and rights, access to and the utilisation of these services by the adolescents remain underutilised in low and middle-income countries. The aim of the study was to explore challenges and improvement strategies of adolescent-friendly health services in the northwest of Namibia. This study employed a qualitative approach utilising an explorative strategy. Semi-structured interviews were used to collect the data. Fifteen nurses were selected using a convenience sampling technique. The interviews were audio recorded, transcribed verbatim and the data were analysed using thematic analysis. The data analysis led to the emergence of the following three themes: Challenges affecting the delivery of Adolescent Friendly Health Services, Challenges affecting participation of adolescent to AFHS and strategies to improve the provision of adolescent-friendly health services. Findings from this study revealed several barriers reportedly faced by adolescents in accessing AFHS as including a lack of comprehensive sexual reproductive health (SRH) services in many healthcare facilities, a lack of trained staff, unfavourable environments for adolescents, a lack of information about the services provided, and recruitment of providers who are not friendly to young people and adolescents. This study findings may lead to an improvement in the provision of such services in healthcare settings. The study can lead to an improvement in the provision of adolescent-friendly services in health care settings. It can help the Ministry of Health and Social Services, along with its agencies, to formulate strategies that can be used to mitigate the challenges d in the provision of adolescent-friendly services.


Malgré les accords mondiaux sur la santé et les droits sexuels et reproductifs des adolescents, l'accès et l'utilisation de ces services par les adolescents restent sous-utilisés dans les pays à revenu faible ou intermédiaire. Le but de l'étude était d'explorer les défis et les stratégies d'amélioration des services de santé adaptés aux adolescents dans le nord-ouest de la Namibie. Cette étude a utilisé une approche qualitative utilisant une stratégie exploratoire. Des entretiens semi-structurés ont été utilisés pour collecter les données. Quinze infirmières ont été sélectionnées à l'aide d'une technique d'échantillonnage de convenance. Les entretiens ont été enregistrés audio, transcrits textuellement et les données ont été analysées par analyse thématique. L'analyse des données a conduit à l'émergence des trois thèmes suivants : les défis affectant la prestation de services de santé adaptés aux adolescents, les défis affectant la participation des adolescents à l'AFHS et les stratégies visant à améliorer la fourniture de services de santé adaptés aux adolescents. Les résultats de cette étude ont révélé plusieurs obstacles auxquels les adolescents seraient confrontés pour accéder à l'AFHS, notamment le manque de services complets de santé sexuelle et reproductive (SSR) dans de nombreux établissements de santé, le manque de personnel qualifié, les environnements défavorables pour les adolescents, le manque d'informations sur les services. Fournis et le recrutement de prestataires peu amicaux envers les jeunes et les adolescents. Les résultats de cette étude pourraient conduire à une amélioration de la fourniture de tels services dans les établissements de soins de santé. L'étude peut conduire à une amélioration de la fourniture de services adaptés aux adolescents dans les établissements de soins de santé. Il peut aider le ministère de la Santé et des Services sociaux, ainsi que ses agences, à formuler des stratégies pouvant être utilisées pour atténuer les défis liés à la fourniture de services adaptés aux adolescents.

ABSTRACT

BACKGROUND: Globally, healthcare workers (HCWs) in maternity units are at high risk of developing burnout. Burnout can lead to multiple harmful impacts on HCWs, their patients, and the broader healthcare system. Little is known about the burden of burnout among sub-Saharan African HCWs. Although evidence suggests that maternity unit doctors in a hospital complex in Namibia are at risk of developing burnout, no studies have been conducted on doctors in this department yet. METHODS: Through participant observation and a mixed-methods needs assessment, this study aimed to explore the drivers, experiences, and impact of burnout symptoms among doctors in this department, and current support mechanisms in place. Survey data was collected from 18 participants and seven in-depth interviews were conducted. Burnout risk was assessed using the Burnout Assessment Tool. RESULTS: Seven out of 18 participants were at very high risk for burnout and three were at risk, showing a high prevalence of burnout risk. Burnout risk remained similar between levels of staff, while gender qualitatively impacted burnout-related experiences. Drivers of burnout were identified at personal, occupational, and systemic levels. CONCLUSIONS: Over half of participants were at risk or at very high risk of burnout. Results highlighted a need for support and identified areas for intervention and further research. Such areas include blame culture, lack of trust between colleagues, and systemic drivers of burnout. This study contributes to the understanding of burnout among HCWs in sub-Saharan Africa.
