Harnessing peer mentorship as a tool to turn human resource for health brain drain into brain gain: a case study of a Nigerian peer-mentored research group.

BACKGROUND: Peer mentorship can be a potential tool to reduce the disparities in health research capacity between high- and low- and middle-income countries. This case study describes the potential of peer mentorship to tackle two critical issues: bridging health research capacity of doctors from low- and middle-income countries (LMICs) and the transformation of human resource for health brain drain into "brain gain". CASE PRESENTATION: In 2021, a virtual peer mentorship group was established by 16 alumni of the University of Benin College of Medical Sciences' 2008 graduating class, residing across three continents. This program aimed to facilitate research collaboration and skill development among colleagues with diverse research experience levels, fostering a supportive environment for career development in research. The group relied heavily on digital technology to carry out its activities due to the different geographical locations of the group members. Led by experienced peer leaders, the group fostered a collaborative learning environment where members leveraged each other's expertise. Within 18 months, we published two research papers in high-impact peer-reviewed global health journals, launched a mixed-methods research study, and conducted training sessions on research design and implementation. Findings from our work were presented at conferences and workshops. However, logistical hurdles, competing priorities, structural constraints, and uneven participation presented challenges. CONCLUSION: The peer mentorship collaboration has achieved some successes so far, and this model can be emulated by other cohorts of medical professionals across LMICs. Despite the group's success at a micro- or individual level, there remain significant structural barriers to research capacity building in LMICs that can only be addressed at the meso- and macro-levels by institutions and government, respectively. A systems-level approach is required to develop and support research capacity building and foster global research collaboration and effectively turn brain drain into brain gain.

Outcome of Emergency Blood Transfusion in Children Seen at a Tertiary Children's Hospital in Freetown: A Descriptive Cross-sectional Study.

OBJECTIVE: This study sought to describe the prevalence and clinical outcome after emergency blood transfusion among children presenting with severe anemia in a tertiary children's hospital in Sierra Leone. METHOD: This was a retrospective study of 395 children who received emergency blood transfusion at the Ola During Children's Hospital in Freetown. Association between mortality and sociodemographic and clinical factors was assessed using χ2 test. Statistical significance was set at P < 0.05. RESULTS: Three hundred ninety-five of 4719 children (8.4%) admitted to the emergency room of the Ola During Children's Hospital received emergency blood transfusion within 24 hours of presentation. Twenty-five (6.3%) were excluded because of incomplete data. The median age of the subjects was 24 months (interquartile range, 14-48). There were 191 boys (51.6%) and 179 girls (48.4%), giving a male/female ratio of 1.06:1. The most common indication for emergency transfusion was severe malaria anemia (67.8%). The mean hemoglobin concentration before transfusion was 4.8 g/dL (±1.4 g/dL). A total of 339 children (91.6%) were discharged home, 8 (2.2%) were discharged against medical advice, and 23 children (6.2%) died. The median length of stay on admission was 3 days (interquartile range, 2-5). Children with severe sepsis (P < 0.001) and those with pretransfusion hemoglobin concentration less than 5% (P = 0.047) were significantly more likely to die after transfusion compared with the other categories of patients. In a multivariate regression analysis, none of the factors were independently associated with clinical outcome after blood transfusion in children who received emergency blood transfusion. CONCLUSION: The study suggests that emergency blood transfusion in children with severe anemia may improve in-hospital survival.

Drivers of health workers' migration, intention to migrate and non-migration from low/middle-income countries, 1970-2022: a systematic review.

BACKGROUND: The migration of healthcare workers (HWs) from low/middle-income countries (LMICs) is a pressing global health issue with implications for population-level health outcomes. We aimed to synthesise the drivers of HWs' out-migration, intention to migrate and non-migration from LMICs. METHODS: We searched Ovid MEDLINE, EMBASE, CINAHL, Global Health and Web of Science, as well as the reference lists of retrieved articles. We included studies (quantitative, qualitative or mixed-methods) on HWs' migration or intention to migrate, published in either English or French between 1 January 1970 and 31 August 2022. The retrieved titles were deduplicated in EndNote before being exported to Rayyan for independent screening by three reviewers. RESULTS: We screened 21 593 unique records and included 107 studies. Of the included studies, 82 were single-country studies focusing on 26 countries, while the remaining 25 included data from multiple LMICs. Most of the articles focused on either doctors 64.5% (69 of 107) and/or nurses 54.2% (58 of 107). The UK (44.9% (48 of 107)) and the USA (42% (45 of 107)) were the top destination countries. The LMICs with the highest number of studies were South Africa (15.9% (17 of 107)), India (12.1% (13 of 107)) and the Philippines (6.5% (7 of 107)). The major drivers of migration were macro-level and meso-level factors. Remuneration (83.2%) and security problems (58.9%) were the key macro-level factors driving HWs' migration/intention to migrate. In comparison, career prospects (81.3%), good working environment (63.6%) and job satisfaction (57.9%) were the major meso-level drivers. These key drivers have remained relatively constant over the last five decades and did not differ among HWs who have migrated and those with intention to migrate or across geographical regions. CONCLUSION: Growing evidence suggests that the key drivers of HWs' migration or intention to migrate are similar across geographical regions in LMICs. Opportunities exist to build collaborations to develop and implement strategies to halt this pressing global health problem.

Understanding the trends, and drivers of emigration, migration intention and non-migration of health workers from low-income and middle-income countries: protocol for a systematic review.

INTRODUCTION: The WHO estimates a shortage of 18 million health workers (HWs) by 2030, primarily in low-income and middle-income countries (LMICs). The perennial out-migration of HWs from LMICs, often to higher-income countries, further exacerbates the shortage. We propose a systematic review to understand the determinants of HWs out-migration, intention to migrate and non-migration from LMICs. METHODS AND ANALYSIS: This protocol was designed in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols guideline for the development and reporting of systematic review protocols. We will include English and French language primary studies (quantitative or qualitative) focused on any category of HWs; from any LMICs; assessed migration or intention to migrate; and reported any determinant of migration. A three-step search strategy that involves a search of one electronic database to refine the preliminary strategy, a full search of all included databases and reference list search of included full-text papers for additional articles will be employed. We will search Ovid MEDLINE, EMBASE, CINAHL, Global Health and Web of Science from inception to August 2022. The retrieved titles will be imported to EndNote and deduplicated. Two reviewers will independently screen all titles and abstract for eligibility using Rayyan. Risk of bias of the individual studies will be determined using the National Institute of Health study quality assessment tools for quantitative studies and the 10-item Critical Appraisal Skills Programme checklists for qualitative studies. The results will be presented in the form of narrative synthesis using a descriptive approach ETHICS AND DISSEMINATION: We will not seek ethical approval from an institutional review board, as this is a systematic review. At completion, we will submit the report of this review to a peer-reviewed journal for publication. Key findings will be presented at local and international conferences.

Evaluation of Predictors of Mortality Associated With Childhood Heart Failure in Nigeria: A 2-Center Study.

OBJECTIVE: The aim of this study was to evaluate the predictors of mortality in childhood heart failure (HF) in 2 tertiary hospitals. METHODS: A 51-month retrospective review of case notes of children with HF admitted into children's emergency rooms of 2 tertiary centers in Southern Nigeria was done. Bio-data and certain sociodemographic variables including mortality were abstracted. Bivariate and multivariate analyses were done to evaluate the predictors of mortality in HF. RESULTS: The case notes of 289 children were analyzed, consisting of 153 males (52.9%) and 142 infants (49.1%). Lower respiratory tract infections, 121 (41.9%), were the commonest causes of HF. Twenty-eight children (9.7%) died. In multivariate analyses, only late presentation (P < 0.0001) was an independent predictor of mortality in HF. CONCLUSION: Education of the populace about early presentation to hospital is imperative to prevent unnecessary deaths associated with HF.

Pre-anesthetic echocardiographic findings in children undergoing non-cardiac surgery at the University of Benin Teaching Hospital, Nigeria.

BACKGROUND: A pre-anaesthestic echocardiogram (echo) is requested for most non-cardiac surgeries to identify possible cardiac structural anomalies. OBJECTIVE: To describe the prevalence and spectrum of structural cardiac abnormalities seen in various non-cardiac conditions. METHODS: We carried out a retrospective review of pre-anaesthetic echos performed over five years on children scheduled for non-cardiac surgery. The requests were categorised according to referring specialities, and the biodata and echo findings were noted. RESULTS: A total of 181 children and 181 echocardiograms were studied, and 100 (55.2%) of the patients were male. Most of the children (87, 48.1%) with oro-facial clefts were referred from dentistry. Of the 181 children, 39 (21.5%) had cardiac abnormalities, most (34, 87.2%) of whom had congenital heart disease (CHD). Ophthalmic requests with suspected congenital rubella syndrome (CRS) had the highest prevalence of 8/12 (66.7%) while the lowest was oro-facial clefts at 15/87 (17.2%). Atrial septal defect was the commonest abnormality, found in 14 patients (35.9%). CONCLUSION: Pre-anaesthetic echo should be performed, especially for children with suspected CRS and other congenital anomalies, requiring non-cardiac surgery.
