RESUMO

Little evidence exists on the design and implementation of anticipatory action (AA) in complex crises. This article examines a 2022 United Nations 'early action' pilot in South Sudan in advance of extreme flooding. As a case study of efforts to act in a complex crisis, it contributes to learning on assisting conflict-affected and displaced populations in advance of extreme weather events. The research points towards the possibility and value of implementing forecast-informed early action in complex contexts with limited forecast skills and multiple hazards when trigger-based AA is not possible. It also argues for the need to link AA implemented in complex crises to development and peacebuilding actors and processes. More broadly, examining the perceptions and processes of AA in the form of early action, rather than a formal AA framework, is highly relevant for the AA community as attention is increasingly placed on providing AA in countries affected by fragility and conflict.

RESUMO

Background: Unpredictable events, such as the outbreak of infectious diseases and humanitarian crises, are putting a strain on health care systems. As a result, African countries will need to prepare themselves with appropriate strategies to withstand such occurrences. Therefore, the purpose of this scoping review was to map available evidence about what type and what components of health systems are needed to help countries cope with health emergencies and to foster health system resilience in the WHO African Region. Methods: A systematic search was performed independently in Scopus and PubMed electronic databases as well as grey literature. Studies were selected based on set eligibility criteria based on the Joanna Brigg's Institute (JBI) methodology for scoping reviews. The key findings were focused on health system resilience and were mapped based on the WHO's core health system components. Our data were tabulated, and a narrative synthesis was conducted. Results: A total of 28 studies were included in this scoping review, mostly conducted in the WHO African Region and region of the Americas. Studies focused on a variety of strategies, such as the continuous delivery of essential services, the strengthening of the health workforce, including community health care workers, community engagement, the provision of protective mechanisms for the health workforce, and flexible leadership and governance measures. Conclusion: Our findings suggest that strategies to improve health system resilience must include all areas of the healthcare delivery process, including primary care. A resilient health system should be ready for a crisis and have adaptable policies in place to offer adequate response at all levels, as well as post-recovery planning. Such health systems should also seek for continuous improvement. More research is needed to assess the efficacy of initiatives for improving health system resilience, particularly in vulnerable African health systems.

RESUMO

In addition to current challenges in food production arising from climate change, soil salinization, drought, flooding, and human-caused disruption, abrupt sunlight reduction scenarios (ASRS), e.g., a nuclear winter, supervolcano eruption, or large asteroid or comet strike, are catastrophes that would severely disrupt the global food supply and decimate normal agricultural practices. In such global catastrophes, teragrams of particulate matter, such as aerosols of soot, dust, and sulfates, would be injected into the stratosphere and block sunlight for multiple years. The reduction of incident sunlight would cause a decrease in temperature and precipitation and major shifts to climate patterns leading to devastating reductions in agricultural production of traditional food crops. To survive a catastrophic ASRS or endure current and future disasters and famines, humans might need to rely on post-catastrophic foods, or those that could be foraged, grown, or produced under the new climate conditions to supplement reduced availability of traditional foods. These foods have sometimes been referred to as emergency, alternate, or resilient foods in the literature. While there is a growing body of work that summarizes potential post-catastrophic foods and their nutritional profiles based on existing data in the literature, this article documents a list of protocols to experimentally determine fundamental nutritional properties of post-catastrophic foods that can be used to assess the relative contributions of those foods to a balanced human diet that meets established nutritional requirements while avoiding toxic levels of nutrients. © 2024 The Author(s).

RESUMO

Background Hypertensive emergencies represent high-cardiovascular-risk situations defined by severe increases in blood pressure. The prevalence of hypertension in non-ST elevation myocardial infarction (NSTEMI) is higher compared to STEMI and there is a lack of studies on NSTEMI patients with hypertensive emergencies. Patients with diabetes exhibited a higher rate of hypertensive emergencies. This study's primary aim was to investigate the coronary artery disease profile in hypertensive emergency patients with NSTEMI, and the secondary aim was to determine the impact of diabetes on the development of hypertensive emergencies. Methodology A total of 100 patients with NSTEMI and hypertensive emergency presenting to the hospital were enrolled in the study. The duration of the study was 24 months. The patients were also sub-grouped into diabetic and nondiabetic. Baseline characteristics were noted, and coronary angiogram and renal angiogram were also done. Based on variables, the chi-square test and t-test were employed to assess the significance. P-value < 0.05 was considered statistically significant. Results The mean age at presentation for patients with NSTEMI and hypertensive emergency was 58 years. Patients consuming alcohol were slightly higher (28, 28%) than those who smoked (23, 23%). Among all, 48 (48%) patients had diabetes. When considering the number of vessels, diabetic patients had more single-vessel diseases (18, 37.5%) and nondiabetic patients had more double-vessel diseases (15, 28.8%). The mean ejection fraction of the diabetic group was 56.1% ± 6.8% and the nondiabetic group was 54.2% ± 7.7%. Among all the patients, 52 (62.6%) used combination drugs, while 39 (46.9%) were on defaulter drugs. Conclusions Several risk factors like age, smoking, alcohol, and nonadherence to drugs were found to have an association with the occurrence of hypertensive emergency. Diabetes was found to be significantly associated with unfavorable coronary anatomy among the population.

RESUMO

Background: University students often experience psychological strains such as academic stress, particularly as they approach the transition into the workforce. This stress may have been heightened for nursing students who completed internships during the COVID-19 pandemic. This study aims to analyze the impact of the COVID-19 pandemic on the perceived stress levels of undergraduate nursing students. Methodology: A cross-sectional descriptive observational study was conducted using the Spanish version of the PSS-10 scale, a validated reduction of the English version PSS-14, to evaluate perceived stress. The responses are Likert-type with a total score range of 0 to 40. Questionnaires were distributed electronically to nursing students across all academic years who were engaged in clinical practice. Participation was voluntary. Results: The study included 487 students, the majority of whom were women (78.4%) with an average age of 23.51 years. Most participants were in their third and fourth years (67%). The mean perceived stress score was 20.65 (SD = 5.62) out of a possible 40, indicating moderate stress levels. Statistically significant differences in perceived stress were found between genders, with women reporting higher stress levels than men (Mann-Whitney U = 15,380.000; p < 0.001). Additionally, a significant correlation was observed between the overall perceived stress score and gender, as well as between specific items on the PSS-10 scale and gender, highlighting the importance of gender-specific stress management interventions. Conclusions: Nursing students reported moderate levels of perceived stress, with women experiencing higher stress levels than men. These findings highlight the need for targeted stress management interventions for nursing students, especially during health crises. Addressing gender-specific stressors and fostering a supportive educational environment will enhance students' well-being, academic success, and professional preparedness.

RESUMO

BACKGROUND: Self-injurious thoughts and behaviors (SITBs) are increasing dramatically among children and adolescents. Crisis support is intended to provide immediate mental health care, risk mitigation, and intervention for those experiencing SITBs and acute mental health distress. Digital mental health interventions (DMHIs) have emerged as accessible and effective alternatives to in-person care; however, most do not provide crisis support or ongoing care for children and adolescents with SITBs. OBJECTIVE: To inform the development of digital crisis support and mental health care for children and adolescents presenting with SITBs, this study aims to (1) characterize children and adolescents with SITBs who participate in a digital crisis response service, (2) compare anxiety and depressive symptoms of children and adolescents presenting with SITBs versus those without SITBs throughout care, and (3) suggest future steps for the implementation of digital crisis support and mental health care for children and adolescents presenting with SITBs. METHODS: This retrospective study was conducted using data from children and adolescents (aged 1-17 y; N=2161) involved in a pediatric collaborative care DMHI. SITB prevalence was assessed during each live session. For children and adolescents who exhibited SITBs during live sessions, a rapid crisis support team provided evidence-based crisis support services. Assessments were completed approximately once a month to measure anxiety and depressive symptom severity. Demographics, mental health symptoms, and change in the mental health symptoms of children and adolescents presenting with SITBs (group with SITBs) were compared to those of children and adolescents with no SITBs (group without SITBs). RESULTS: Compared to the group without SITBs (1977/2161, 91.49%), the group with SITBs (184/2161, 8.51%) was mostly made up of adolescents (107/184, 58.2%) and female children and adolescents (118/184, 64.1%). At baseline, compared to the group without SITBs, the group with SITBs had more severe anxiety and depressive symptoms. From before to after mental health care with the DMHI, the 2 groups did not differ in the rate of children and adolescents with anxiety symptom improvement (group with SITBs: 54/70, 77% vs group without SITBs: 367/440, 83.4%; χ21=1.2; P=.32) as well as depressive symptom improvement (group with SITBs: 58/72, 81% vs group without SITBs: 255/313, 81.5%; χ21=0; P=.99). The 2 groups also did not differ in the amount of change in symptom severity during care with the DMHI for anxiety (t80.20=1.37; P=.28) and depressive (t83.75=-0.08; P=.99) symptoms. CONCLUSIONS: This study demonstrates that participation in a collaborative care DMHI is associated with improved mental health outcomes in children and adolescents experiencing SITBs. These results provide preliminary insights for the use of pediatric DMHIs in crisis support and mental health care for children and adolescents presenting with SITBs, thereby addressing the public health issue of acute mental health crisis in children and adolescents.

RESUMO

Systemic arterial hypertension (HTN) is the main cause of morbidity and mortality, and HTN crises contribute significantly to an unfavourable clinical course. For decades, HTN crises have been dichotomized into hypertensive emergency (HTN-E) and hypertensive urgency (HTN-U). The main difference between the two is the presence of acute hypertension-mediated organ damage (HMOD) - if HMOD is present, HTN crisis is HTN-E; if not, it is HTN-U. Patients with HTN-E are in a life-threatening situation. They are hospitalized and receive antihypertensive drugs intravenously (IV). On the other hand, patients with HTN-U are usually not hospitalized and receive their antihypertensives orally. We suggest a modification of the current risk stratification scheme for patients with HTN crises. The new category would be the intermediate risk group, more precisely the 'impending HTN-E' group, with a higher risk in comparison to HTN-U and a lower risk than HTN-E. 'Impending HMOD' means that HMOD has not occurred (yet), and the prognosis is, therefore, better than in patients with ongoing HMOD. There are three main reasons to classify patients as having impending HTN-E: excessively elevated BP, high-risk comorbidities, and ongoing bleeding/high bleeding risk. Their combinations are probable. This approach may enable us to prevent some HTNEs by avoiding acute HMOD using a timely blood pressure treatment. This treatment should be prompt but controlled.

RESUMO

This case report describes the radiofrequency (RF) ablation of a pheochromocytoma in a 35-year-old female with multiple endocrine neoplasia (MEN) II syndrome, who previously underwent a right adrenalectomy and thyroidectomy. The patient presented with a new tumor in the left adrenal gland, detected via imaging, without evidence of metastasis. Opting against surgical adrenalectomy due to previous surgeries, she underwent RF ablation after preparatory alpha and beta blockader. During RF ablation, a hypertensive crisis occurred, managed effectively with nitroprusside sodium and supportive measures. Postprocedure recovery was uneventful, with normal metanephrine levels and imaging indicating successful ablation. This report highlights the feasibility and challenges of using RF ablation for adrenal pheochromocytoma, suggesting a potential shift towards less invasive management for select cases.

RESUMO

PROBLEM: Limited research has examined and synthesized the adaptation of midwives and midwife-led interventions during crises. BACKGROUND: Evidence suggests that midwives are essential to respond to sexual and reproductive health care needs during disruptive times, and that they adapt to continue to provide their services during those circumstances. AIM: To map the adaptations of midwives when providing care during crises globally. Secondary objectives include identifying which midwives adapted, what services were adapted and how, and the demographic receiving care. STUDY METHODS: Scoping review using Levac's modifications of Arksey and O'Malley's methods. Publications and grey literature, in English and Spanish, with no limitations based on study design or date were included. Data was extracted and mapped using Wheaton and Maciver's Adaptation framework. FINDINGS: We identified 3329 records, of which forty-two were included. Midwives' prior training impacted adaptation. Midwives adapted to the COVID-19 pandemic, epidemics, natural disasters, and World War II. They adapted in hospital and community settings around the provision of antenatal, labor and birth, postpartum, and contraceptive care. However, no specific data identified population demographics. Midwifery adaptations related to their practice, role, and scope of practice. CONCLUSION: The limited available evidence identified the challenges, creativity, and mutual aid activities midwives have undertaken to ensure the provision of their services. Evidence is highly concentrated around maternal health services. Further high-quality research is needed to provide a deeper understanding of how midwifery-led care can adapt to guide sustainable responses to ensure access to sexual and reproductive health services during crises.

RESUMO

The current humanitarian crises in Ukraine and Gaza, along with the chronic crises, and the climate-related disasters, have exposed the limitations of the humanitarian system. Within these contexts, humanitarian organisations frequently struggle with collecting, analysing, interpreting, and utilising health data, due to the challenging environments in which they operate and funding constraints. It is precisely in these contexts that field epidemiology plays a crucial, but often overlooked role.Field epidemiologists face unique challenges, including rapidly changing conditions, poor-quality data, and biases. Despite these difficulties, accurate epidemiological data are essential for needs assessment, guidance on interventions, and advocacy. Conventional methods often need adaptation for crisis settings, and there are still gaps in measurement.This article discusses the role of epidemiology in such contexts, noting a shortage of trained 'humanitarian epidemiologists' and specialised training as major issues.To address these needs, the Italian Association of Epidemiology organised a course in early 2024 to enhance the epidemiological skills of staff working in humanitarian crises and introduce traditional epidemiologists to crisis-specific challenges. The course covered key concepts and methods of field epidemiology, emphasising the use of secondary health data. Its positive reception underscored the demand for such specialised training.Improving public health information collection and use in humanitarian crises is an ethical and practical necessity. Indeed, investing in field epidemiology and recognising its importance can enhance humanitarian interventions and better serve vulnerable populations.

RESUMO

PURPOSE: This study examines how local user associations of mental health service-user organizations were affected by the pandemic, in order to provide guidance to user organizations and surrounding actors on future advancements. The pandemic is used as a case to explore organizational resilience and digitalization during crisis. METHODS: Data from focus group interviews and individual interviews with representatives of ten local associations were analysed using qualitative content analysis. A theoretical framework combining governance theory and organizational theory was applied. RESULTS: Typically, associations swiftly restructured activities to support members to meet the urgent needs that arose, not least in relation to the digital transition. Simultaneously, face-to-face interactions was valued and some members became isolated. Public sector actors often did not prioritize collaboration, and the associations had limited agency and influence in advocacy activities. CONCLUSIONS: User organizations can play an important role in times of crisis. Surrounding social systems should provide resources to counteract resource dependencies and allow organizations to develop operating reserves. They should value collaboration and establish collaborative practices to ensure a readiness to utilize the organizations' capacities when needed. User organizations should have control over future developments, both to harness the potential of digital connectivity and to prevent a digital divide.

RESUMO

In Africa, compared to 2019, dengue infections have surged ninefold by December 2023, with over 270 000 cases and 753 deaths reported across 18 African Union (AU) Member States. This commentary synthesises the context of dengue outbreaks in Africa and provides recommendations for sustainable control. In 2023, 18 African Union Member States reported outbreaks of dengue, among which seven had ongoing armed conflicts. These countries were amongst the top 15 African countries contributing to the most displaced persons on the continent and accounted for 98% of all dengue cases reported in the continent in 2023. Climate change remains an important driver, both through the displacement of people and global warming. The continent continues to face several challenges in detection, reporting and management, such as the lack of local laboratory capacity, misclassification of dengue cases and lack of medical countermeasures. Solutions targeting the strengthening of cross-border surveillance and early warning systems using a multisectoral one-health approach, local research and development for therapeutics and diagnostics and community engagement empowering communities to protect themselves and understand the gravity of the threat could help curb the spread of the disease in Africa.

RESUMO

OBJECTIVE: To delineate the natural history of splenic complications other than loss of splenic function in children with sickle cell disease (SCD), we performed a retrospective chart review of patients with SCD treated at the Texas Children's Hospital. METHODS: We determined the dates of diagnoses of splenic complications, the number of acute splenic sequestration crises (ASSC), and hydroxyurea treatment in pediatric patients with SCD. We also examined the association of hydroxyurea therapy with the onset and severity of ASSC. RESULTS: The cumulative prevalence of splenic complications was 24.7% for splenomegaly, 24.2% for ASSC, 9.6% for hypersplenism, and 5.6% for splenectomy. The cumulative prevalence of splenic complications was highest in patients with hemoglobin Sß0 (69.2%), intermediate in hemoglobin SS (33.3%), low in hemoglobin SC (9.0%), and non-existent in hemoglobin Sß+. The overall event rate of ASSC was 8.3 per 100 patient-years. The event-rate was 28.4 for hemoglobin Sß0, 10.9 for hemoglobin SS, and 3.5 for hemoglobin SC. Patients with hemoglobin SS and hemoglobin Sß0 on hydroxyurea therapy had a significantly higher occurrence of ASSC than those who were not, with event rates of 14.2 and 3.1, respectively. The event rate was also higher for children who started hydroxyurea before age 2 years than for those who started after this age (19.8 and 9.2, respectively). CONCLUSIONS: The prevalence and severity of splenic problems vary widely between different sickle cell genotypes, with hemoglobin Sß0 having the most severe complications. Hydroxyurea therapy is associated with increased incidence of ASSC, particularly when initiated before 2 years of age.

RESUMO

A growing body of research is categorizing sex differences in both sickle cell anemia (SCA) and acute kidney injury (AKI); however, most of this work is being conducted in high-resource settings. Here, we evaluated risk factors and clinical parameters associated with AKI and AKI severity, stratified by sex, in a cohort of children hospitalized with SCA and vaso-occlusive pain crisis (VOC). The purpose of this study was to explore sex disparities in a high-risk, vulnerable population. This study was a secondary analysis of data collected from a cohort of Ugandan children between 2 and 18 yr of age prospectively enrolled. A total of 185 children were enrolled in the primary study; 41.6% were female and 58.4% were male, with a median age of 8.9 yr. Incident or worsening AKI (P = 0.026) occurred more frequently in female compared with male children, despite no differences in AKI on admission. Female children also had altered markers of renal function including higher creatinine levels at admission (P = 0.03), higher peak creatinine (P = 0.006), and higher urine neutrophil gelatinase-associated lipocalin (NGAL) at admission (P = 0.003) compared with male children. Female children had elevated total (P = 0.045) and conjugated bilirubin at admission (P = 0.02) compared with male children and higher rates of hematuria at admission (P = 0.004). Here, we report sex differences in AKI in children with SCA and VOC, including increased incidence and worsening of AKI in female pediatric patients, in association with an increase in biological indicators of poor renal function including creatinine, estimated glomerular filtration rate, and NGAL.NEW & NOTEWORTHY In this study, we report an increased risk of developing acute kidney injury (AKI) during hospitalization, worsening AKI, and death among females with sickle cell anemia (SCA) hospitalized with an acute pain crisis compared with males. The sex differences in AKI were not explained by socioeconomic differences, severity of pain, or disease severity among females compared with males. Together, these data suggest that female children with SCA may be at increased risk of AKI.

RESUMO

Background: Sickle cell disease (SCD) is a major public health issue worldwide with high morbidity and mortality. SCD SD Punjab is the third most common genotype of SCD in Oman and is associated with several serious complications. The aim of the study is to establish the clinical and laboratory features of SCD patients with SD double heterozygotes and study the impact of haemoglobin F, hydroxyurea, and other modulators on the disease severity. Methods: We analysed the electronic medical records of 52 consecutive SCD patients who were diagnosed as double heterozygote SD Punjab between 2006 and 2022. The study was approved by the local medical research and ethics committee. The data captured included SCD-related complications and current clinical and laboratory indices. Data from other studies on other SCD genotypes were used as historical controls. Results: 52 patients (31 males, 21 females) who formed this cohort had a median age of 32 years with an interquartile range (IQR) of 21-39.8 years. 37(71.2%) had <3 VOC per year, whereas 15 (28.8%) patients had ≥3 vasooclusive (VOC) episodes per year. SCD-related complications included Acute Chest Syndrome (ACS) (48%), Gall stones (26.9%), Avascular necrosis (AVN) (28.8%), Stroke (13.5%) and splenic sequestration (7.7%), whereas 5 (9.6%) patients of this cohort died. Surgical and Autosplenectomy were seen in 18 (34.6%). These findings were similar to other SCD genotypes in this community. 19 (57.6%) were taking Hydroxyurea (HU) amongst the 33 patients who were prescribed HU. Haematological parameters showed a median (IQR) Hb (g/dl), MCV (fl), Retic count (%), WBC count(×109/L) and Platelet count(×109/L) of 9.7 (8.5-11.3), 74.9 (68.4-79.8), 4 (3.2-5.7), 9.9 (8.1-12.6) and 309 (239-428) respectively. The haemoglobin electrophoresis showed an elevated HbF, whereas serum bilirubin and LDH were elevated amongst the biochemical parameters. The use of hydroxyurea showed no impact on VOC, ACS, AVN, Stroke or mortality. Conclusion: SD Punjab is the third most common SCD genotype in Oman and was associated with recurrent VOC, ACS, AVN, and gall stones comparable to other SCD genotypes. Patients with > 3 VOC/year had significantly increased incidence of Stroke, AVN, and gallstones. However, HU was not associated with improved prognosis and better survival in this cohort of patients.

RESUMO

Splenic sequestration crisis is a life-threatening complication of sickle cell disease (SCD), characterized by a sudden and huge accumulation of blood in the spleen, leading to rapid enlargement and may lead to organ failure. This case report discusses an unusual case of a splenic sequestration crisis in an adult with SCD. The patient's age, Parvovirus B19 infection, and concurrent retrocardiac pneumonia are all things that differentiate this case from our usual presentation. We will be discussing the clinical presentation, diagnostic methods, and management.

RESUMO

TANGO2 deficiency disease (TDD) is a rare genetic disorder estimated to affect ∼8000 individuals worldwide. It causes neurodegeneration often accompanied by potentially lethal metabolic crises that are triggered by diet or illness. Recent work has demonstrated distinct lipid imbalances in multiple model systems either depleted for or devoid of the TANGO2 protein, including human cells, fruit flies and zebrafish. Importantly, vitamin B5 supplementation has been shown to rescue TANGO2 deficiency-associated defects in flies and human cells. The notion that vitamin B5 is needed for synthesis of the lipid precursor coenzyme A (CoA) corroborates the hypothesis that key aspects of TDD pathology may be caused by lipid imbalance. A natural history study of 73 individuals with TDD reported that either multivitamin or vitamin B complex supplementation prevented the metabolic crises, suggesting this as a potentially life-saving treatment. Although recently published work supports this notion, much remains unknown about TANGO2 function, the pathological mechanism of TDD and the possible downsides of sustained vitamin supplementation in children and young adults. In this Perspective, we discuss these recent findings and highlight areas for immediate scientific attention.

RESUMO

'Forgotten crises' constitute a permanent background to any present and future global humanitarian and development efforts. They represent a significant impediment to promoting lasting peace given concurrent catastrophes exacerbated by climate change. Yet, they are routinely neglected and remain unresolved. Building on critical and feminist approaches, this paper theorises them as forgotten sites of local knowledge production. It asks: what is local knowledge of and from forgotten crises? How can it be recovered and resignified, and what lessons can such knowledge provide at the global level? Drawing on examples from the intersections of conflict, disasters, and pandemics in the Philippines, the paper makes a case for valuing local knowledge arising from forgotten crises because of its potential contribution to adapting global humanitarian and development systems to address crises on multiple fronts. Such epistemic margins are generative of vantage points that can present a fuller account of how different crises interact and how best to respond to them.

RESUMO

Background: Massive open online courses (MOOCs) are increasingly used to educate health care workers during public health emergencies. In early 2020, the World Health Organization (WHO) developed a series of MOOCs for COVID-19, introducing the disease and strategies to control its outbreak, with 6 courses specifically targeting health care workers as learners. In 2020, Stanford University also launched a MOOC designed to deliver accurate and timely education on COVID-19, equipping health care workers across the globe to provide health care safely and effectively to patients with the novel infectious disease. Although the use of MOOCs for just-in-time training has expanded during the pandemic, evidence is limited regarding the factors motivating health care workers to enroll in and complete courses, particularly in low-income countries (LICs) and lower-middle-income countries (LMICs). Objective: This study seeks to gain insights on the characteristics and motivations of learners turning to MOOCs for just-in-time training, to provide evidence that can better inform MOOC design to meet the needs of health care workers. We examine data from learners in 1 Stanford University and 6 WHO COVID-19 courses to identify (1) the characteristics of health care workers completing the courses and (2) the factors motivating them to enroll. Methods: We analyze (1) course registration data of the 49,098 health care workers who completed the 7 focal courses and (2) survey responses from 6272 course completers. The survey asked respondents to rank their motivations for enrollment and share feedback about their learning experience. We use descriptive statistics to compare responses by health care profession and by World Bank country income classification. Results: Health care workers completed the focal courses from all regions of the world, with nearly one-third (14,159/49,098, 28.84%) practicing in LICs and LMICs. Survey data revealed a diverse range of professional roles among the learners, including physicians (2171/6272, 34.61%); nurses (1599/6272, 25.49%); and other health care professionals such as allied health professionals, community health workers, paramedics, and pharmacists (2502/6272, 39.89%). Across all health care professions, the primary motivation to enroll was for personal learning to improve clinical practice. Continuing education credit was also an important motivator, particularly for nonphysicians and learners in LICs and LMICs. Course cost (3423/6272, 54.58%) and certification (4238/6272, 67.57%) were also important to a majority of learners. Conclusions: Our results demonstrate that a diverse range of health care professionals accessed MOOCs for just-in-time training during a public health emergency. Although all health care workers were motivated to improve their clinical practice, different factors were influential across professions and locations. These factors should be considered in MOOC design to meet the needs of health care workers, particularly those in lower-resource settings where alternative avenues for training may be limited.
