Prevalence and Severity of Burn Scars in Rural Mozambique.

BACKGROUND: Burn injuries are common in low- and middle-income countries (LMICs) and their associated disability is tragic. This study is the first to explore burn scars in rural communities in Mozambique. This work also validated an innovate burn assessment tool, the Morphological African Scar Contractures Classification (MASCC), used to determine surgical need. METHODS: Using a stratified, population-weighted survey, the team interviewed randomly selected households from September 2012 to June 2013. Three rural districts (Chókwè, Nhamatanda, and Ribáuè) were selected to represent the southern, central and northern regions of the country. Injuries were recorded, documented with photographs, and approach to care was gathered. A panel of residents and surgeons reviewed the burn scar images using both the Vancouver Scar Scale and the MASCC, a validated visual scale that categorizes patients into four categories corresponding to levels of surgical intervention. RESULTS: Of the 6104 survey participants, 6% (n = 370) reported one or more burn injuries. Burn injuries were more common in females (57%) and most often occurred on the extremities. Individuals less than 25 years old had a significantly higher odds of reporting a burn scar compared to people older than 45 years. Based on the MASCC, 12% (n = 42) would benefit from surgery to treat contractures. CONCLUSION: Untreated burn injuries are prevalent in rural Mozambique. Our study reveals a lack of access to surgical care in rural communities and demonstrates how the MASCC scale can be used to extend the reach of surgical assessment beyond the hospital through community health workers.

The burden of recording and reporting health data in primary health care facilities in five low- and lower-middle income countries.

BACKGROUND: Recording and reporting health data in facilities is the backbone of routine health information systems which provide data collected by health facility workers during service provision. Data is firstly collected in a register, to record patient health data and care process, and tallied into nationally designed reporting forms. While there is anecdotal evidence of large numbers of registers and reporting forms for primary health care (PHC) facilities, there are few systematic studies to document this potential burden on health workers. This multi-country study aimed to document the numbers of registers and reporting forms use at the PHC level and to estimate the time it requires for health workers to meet data demands. METHODS: In Cambodia, Ghana, Mozambique, Nigeria and Tanzania, a desk review was conducted to document registers and reporting forms mandated at the PHC level. In each country, visits to 16 randomly selected public PHC facilities followed to assess the time spent on paper-based recording and reporting. Information was collected through self-reports of estimated time use by health workers, and observation of 1360 provider-patient interactions. Data was primarily collected in outpatient care (OPD), antenatal care (ANC), immunization (EPI), family planning (FP), HIV and Tuberculosis (TB) services. RESULT: Cross-countries, the average number of registers was 34 (ranging between 16 and 48). Of those, 77% were verified in use and each register line had at least 20 cells to be completed per patient. The mean time spent on recording was about one-third the total consultation time for OPD, FP, ANC and EPI services combined. Cross-countries, the average number of monthly reporting forms was 35 (ranging between 19 and 52) of which 78% were verified in use. The estimated time to complete monthly reporting forms was 9 h (ranging between 4 to 15 h) per month per health worker. CONCLUSIONS: PHC facilities are mandated to use many registers and reporting forms pausing a considerable burden to health workers. Service delivery systems are expected to vary, however an imperative need remains to invest in international standards of facility-based registers and reporting forms, to ensure regular, comparable, quality-driven facility data collection and use.

Surgical conditions account for the majority of admissions to three primary referral hospitals in rural Mozambique.

BACKGROUND: The World Health Organization has identified the primary referral hospital as its priority site for improving surgical care in low- and middle-income countries. Little is known about the relative burden surgical patients place on health care facilities at this level. This research estimates the fraction of admissions due to surgical conditions at three hospitals in rural Mozambique. METHODS: Prospective data were collected on all inpatients at three primary referral hospitals in Mozambique during a 12-day period. We compared the number of surgical patients and their length of stay (LOS) to the patients admitted to the medicine, pediatric, and maternity wards. These findings were validated using retrospective data collected from one hospital from January to May 2012. RESULTS: Patients with surgical conditions (i.e., patients admitted to the surgical or maternity ward) accounted for 57.5 % of admissions and 48.0 % of patient-days. The majority of patients were admitted to the maternity ward (32.3 %). The other admissions were evenly distributed to the pediatric (22.5 %), medical (20.0 %), and surgical (25.2 %) wards. Compared to patients from the three other wards, surgical patients had longer average LOS (8.7 vs. 1.9-7.7 days) and a higher number of total patient-days (891 vs. 252-703 days). The most prevalent procedures were cesarean section (33.3 %) and laceration repair/wound care (11.8 %). CONCLUSIONS: Surgical conditions are the most common reason for admissions at three primary referral hospitals in rural Mozambique. These data suggest that surgical care is a major component of health care delivered at primary referral hospitals in Mozambique and likely other sub-Saharan African countries.

High SARS-CoV-2 Exposure in Rural Southern Mozambique After Four Waves of COVID-19: Community-Based Seroepidemiological Surveys.

BACKGROUND: Mozambique was one of many African countries with limited testing capacity for SARS-CoV-2. Serosurveys, an alternative to estimate the real exposure to understand the epidemiology and transmission dynamics, have been scarce in Mozambique. Herein, we aimed to estimate the age-specific seroprevalence of SARS-CoV-2 in the general population of the Manhiça District, at four time points, for evaluating dynamics of exposure and the impact of vaccination. METHODS: We conducted four community-based seroepidemiological surveys separated by 3 months between May 2021 and June 2022 to assess the prevalence of SARS-CoV-2 antibodies. An age-stratified (0-19, 20-39, 40-59, and ≥ 60 years) sample of 4810 individuals was randomly selected from demographic surveillance database, and their blood samples were analyzed using WANTAI SARS-CoV-2 IgG + IgM ELISA. Nasopharyngeal swabs from a subsample of 2209 participants were also assessed for active infection by RT-qPCR. RESULTS: SARS-CoV-2 seroprevalence increased from 27.6% in the first survey (May 2021) to 63.6%, 91.2%, and 91.1% in the second (October 2021), third (January 2022), and fourth (May 2022) surveys, respectively. Seroprevalence in individuals < 18 years, who were not eligible for vaccination, increased from 23.1% in the first survey to 87.1% in the fourth. The prevalence of active infection was below 10.1% in all surveys. CONCLUSIONS: A high seroprevalence to SARS-CoV-2 was observed in the study population, including individuals not eligible for vaccination at that time, particularly after circulation of the highly transmissible Delta variant. These data are important to inform decision making on the vaccination strategies in the context of pandemic slowdown in Mozambique.

Strengthening research capacity through the medical education partnership initiative: the Mozambique experience.

BACKGROUND: Since Mozambique's independence, the major emphasis of its higher educational institutions has been on didactic education. Because of fiscal and human resource constraints, basic and applied research activities have been relatively modest in scope, and priorities have often been set primarily by external collaborators. These factors have compromised the scope and the relevance of locally conducted research and have limited the impact of Mozambique's universities as major catalysts for national development. CASE DESCRIPTION: We developed a multi-institutional partnership to undertake a comprehensive analysis of the research environment at Mozambique's major public universities to identify factors that have served as barriers to the development of a robust research enterprise. Based on this analysis, we developed a multifaceted plan to reduce the impact of these barriers and to enhance research capacity within Mozambique. INTERVENTIONS: On the basis of our needs assessment, we have implemented a number of major initiatives within participating institutions to facilitate basic and applied research activities. These have included specialized training programmes, a reorganization of the research administration infrastructure, the development of multiple collaborative research projects that have emphasized local research priorities and a substantial investment in bioinformatics. We have established a research support centre that provides grant development and management services to Mozambique's public universities and have developed an independent Institutional Review Board for the review of research involving human research subjects. Multiple research projects involving both communicable and non-communicable diseases have been developed and substantial external research support has been obtained to undertake these projects. A sizable investment in biomedical informatics has enhanced both connectivity and access to digital reference material. Active engagement with relevant entities within the Government of Mozambique has aligned institutional development with national priorities. CONCLUSIONS: Although multiple challenges remain, over the past 3 years significant progress has been made towards establishing conditions within which a broad range of basic, translational and clinical and public health research can be undertaken. Ongoing development of this research enterprise will enhance capacity to address critical locally relevant research questions and will leverage resources to accelerate the development of Mozambique's national universities.

Fine needle aspiration cytology in Mozambique: Report of a 15-year experience.

BACKGROUND: Fine needle aspiration cytology (FNAC) is an important diagnostic tool in a range of medical settings. It is fast, quick and a highly accurate diagnostic method and can be used, in settings with minimal laboratory infrastructures. METHODS: In this report, we describe the experience in the use of FNAC since it is introduction in 1996 in the Anatomical Pathology Service of the Maputo Central Hospital (MCH), along with more detailed data referring to 2009-2010. RESULTS: The number of FNAC analyses increased gradually from 269 (4.1% of all pathologic tests of the Service) in 1996, when it was introduced in Mozambique, to 3234 (17% of all tests) in 2010. Lymph nodes were the organs most frequently biopsied, followed by breast and soft tissues. Inflammatory conditions, especially tuberculosis, were the most frequent diagnoses (22.2% of the cases), followed by hyperplastic conditions (20.6%), benign tumors (13.4%) and malignant tumors (12.3%). CONCLUSION: Our results clearly demonstrate that even in an environment with poor laboratory resources, it is possible to establish a FNAC clinic that can provide a quick and precise diagnosis for clinicians to aid in early treatment interventions, especially in inflammatory diseases which were the majority of our cases.

Prevalence of Intestinal Parasites Among HIV Infected and HIV Uninfected Patients Treated at the 1° De Maio Health Centre in Maputo, Mozambique.

INTRODUCTION: Increased evidence suggests intestinal parasite infections, one of the major causes of morbidity and mortality in sub-Saharan Africa, increase the acquisition and progression of AIDS. OBJECTIVE: The aim of this study was to determine the prevalence of HIV and intestinal parasite co-infections, the relationship to the degree of immunosuppression and the effect of antiretroviral treatment (ART) and trimethoprim-sulfamethoxazole (TS) on patients treated at 1° de Maio Health Centre in Maputo, Mozambique. METHODS: A cross sectional study was conducted from December 2015 to August 2016. A total of 517 stool samples from 371 (71.8%) HIV infected and 146 (28.2%) HIV uninfected patients were examined for the presence of parasites using direct wet mount, Ritchie and modified Ziehl Neelsen techniques. A subsample of 201 stools from HIV infected patients was processed for coproantigens for the detection of Cryptosporidium spp. RESULTS: Overall, 148 (28.6%) of the individuals were infected with at least one parasite. The prevalence of intestinal parasites was 98 (26.4%) and 50 (34.2%) in HIV infected and uninfected patients, respectively. This difference was not statistically significant. We identified 10 different parasites including (most frequently) Trichuris trichiura 67 (12.9%), Ascaris lumbricoides 27 (5.2%) and Entamoeba coli 40 (7.7%). Giardia intestinalis prevalence was significantly higher in HIV infected patients 12 (3.2%), p = 0.02. Parasitic intensity was higher in HIV infected patients than in HIV uninfected patients. Cryptosporidium spp. prevalence by coproantigen detection was 6% and was associated with degree of immune suppression. A CD4+ T-cell count of < 200 cells/µL was significantly associated with higher prevalence and intensity of parasitism, while ART and TS prophylaxis was associated with lower parasitic prevalence. CONCLUSIONS: Our study revealed that the prevalence and intensity of intestinal parasites in HIV infected patients was related to the degree of immune suppression as assessed by CD4+ cell count, while ART and TS seemed to reduce the parasitic infection.

Surgical patients travel longer distances than non-surgical patients to receive care at a rural hospital in Mozambique.

BACKGROUND: Surgical care is increasingly recognised as an important component of global health delivery. However, there are still major gaps in knowledge related to access to surgical care in low-income countries. In this study, we compare distances travelled by surgical patients with patients seeking other medical services at a first-level hospital in rural Mozambique. METHODS: Data were collected on all inpatients at Hospital Rural de Chókwè in rural Mozambique between 20 June 2012 and 3 August 2012. Euclidean distances travelled by surgical versus non-surgical patients using coordinates of each patient's city of residence were compared. Data were analysed using ArcGIS 10 and STATA. RESULTS: In total, 500 patients were included. Almost one-half (47.6%) lived in the city where the hospital is based. By hospital ward, the majority (62.0%) of maternity patients came from within the hospital's city compared with only 35.2% of surgical patients. The average distance travelled was longest for surgical patients (42 km) compared with an average of 17 km for patients on all other wards. CONCLUSIONS: Patients seeking surgical care at this first-level hospital travel farther than patients seeking other services. While other patients may have access to at community clinics, surgical patients depend more heavily on the services available at first-level hospitals.

A cross-sectional serological study of cysticercosis, schistosomiasis, toxocariasis and echinococcosis in HIV-1 infected people in Beira, Mozambique.

BACKGROUND: Helminthic infections are highly endemic in Mozambique, due to limited access to healthcare and resources for disease prevention. Data on the subclinical prevalence of these diseases are scarce due to the fact that an immunological and imaging diagnosis is not often available in endemic areas. We conducted a cross-sectional study on HIV1(+) patients from Beira city in order to determine the seroprevalence of cysticercosis, schistosomiasis, toxocariasis and echinoccocosis and its possible interaction with HIV infection. METHODOLOGY/PRINCIPAL FINDINGS: Patients (601) were voluntarily recruited at the Ponta Gea Health Center and their demographic and clinical data were recorded (including CD4(+) cell count and antiretroviral regimen). Mean age was 39.7 years, 378 (62.9%) were women and 223 (37.1%) were men. Four hundred seventy-five (475) patients (79%) were already on highly active antiretroviral therapy (HAART), and 90 started therapy after being enrolled in the study. For serological testing we used a Multiplex Western Blot IgG from LDBIO Diagnostics. The overall seroprevalence was 10.2% for cysticercosis, 23% for schistosomiasis, 7.3% for toxocariasis and 17.3% for echinococcosis. CONCLUSIONS/SIGNIFICANCE: Neither age nor the CD4(+) count were significantly associated with the seroprevalence of the helminths studied. However, patients with CD4(+) between 200-500/µl had a higher seroprevalence to all helminths than those with less than 200/µl cells/and those with more than 500 cells/µl. Female gender was significantly associated with cysticercosis and schistosomiasis, and being in HAART with toxocariasis. Headache was significantly associated with cysticercosis and toxocariasis. There was no association between epilepsy and seropositivity to any of the parasites. The study concluded that a clear understanding of the prevalence and manifestations of these coinfections, how best to diagnose subclinical cases, and how to manage diseases with concomitant antiretroviral therapy is needed.

Innovative strategies for transforming internal medicine residency training in resource-limited settings: the Mozambique experience.

With approximately 4 physicians per 100,000 inhabitants, Mozambique faces one of the most severe health care provider shortages in Sub-Saharan Africa. The lack of sufficient well-trained medical school faculty is one of Mozambique's major barrier to producing new physicians annually. A partnership between the Universidade Eduardo Mondlane and the University of California, San Diego, has addressed this challenge with support from the Medical Education Partnership Initiative. After an initial needs assessment involving questionnaires and focus groups of residents, and working with key members from the Ministry of Health, the Medical Council, and Maputo Central Hospital, a set of interventions was designed. The hospital's internal medicine residency program was chosen as the focus for the plan. Interventions included curriculum design, new teaching methodologies, investment in an informatics infrastructure for access to digital references, building capacity to support clinical research, and providing financial incentives to retain junior faculty. The number of candidates entering the internal medicine residency program has increased, and detailed monitoring and evaluation is measuring the impact of these changes on the quality of training. These changes are expected to improve the long-term quality of postgraduate training in general through dissemination to other departments. They also have the potential to facilitate equitable distribution of specialists nationwide by expanding postgraduate training to other hospitals and universities.
