Feasibility of Simulation-Based Medical Education in a Low-Income Country: Challenges and Solutions From a 3-year Pilot Program in Uganda.

STATEMENT: Simulation is relatively new in many low-income countries. We describe the challenges encountered, solutions deployed, and the costs incurred while establishing two simulation centers in Uganda. The challenges we experienced included equipment costs, difficulty in procurement, lack of context-appropriate curricula, unreliable power, limited local teaching capacity, and lack of coordination among user groups. Solutions we deployed included improvisation of equipment, customization of low-cost simulation software, creation of context-specific curricula, local administrative support, and creation of a simulation fellowship opportunity for local instructors. Total costs for simulation setups ranged from US $165 to $17,000. For centers in low-income countries trying to establish simulation programs, our experience suggests that careful selection of context-appropriate equipment and curricula, engagement with local and international collaborators, and early emphasis to increase local teaching capacity are essential. Further studies are needed to identify the most cost-effective levels of technological complexity for simulation in similar resource-constrained settings.

Key bottlenecks to the provision of safe obstetric anaesthesia in low- income countries; a cross-sectional survey of 64 hospitals in Uganda.

BACKGROUND: Despite recent advances in surgery and anaesthesia which significantly improve safety, many health facilities in low-and middle-income countries (LMICs) remain chronically under-resourced with inability to cope effectively with serious obstetric complications (Knight et al., PLoS One 8:e63846, 2013). As a result many of these countries still have unacceptably high maternal and neonatal mortality rates. Recent data at the national referral hospitals in East Africa reported that none of the national referral hospitals met the World Federation of Societies of Anesthesiologists (WFSA) international standards required to provide safe obstetric anaesthesia (Epiu I: Challenges of Anesthesia in Low-and Middle-Income Countries. WFSA; 2014 http://wfsa.newsweaver.com/Newsletter/p8c8ta4ri7a1wsacct9y3u?a=2&p=47730565&t=27996496 ). In spite of this evidence, factors contributing to maternal mortality related to anaesthesia in LMICs and the magnitude of these issues have not been comprehensively studied. We therefore set out to assess regional referral, district, private for profit and private not-for profit hospitals in Uganda. METHODS: We conducted a cross-sectional survey at 64 government and private hospitals in Uganda using pre-set questionnaires to the anaesthetists and hospital directors. Access to the minimum requirements for safe obstetric anaesthesia according to WFSA guidelines were also checked using a checklist for operating and recovery rooms. RESULTS: Response rate was 100% following personal interviews of anaesthetists, and hospital directors. Only 3 of the 64 (5%) of the hospitals had all requirements available to meet the WFSA International guidelines for safe anaesthesia. Additionally, 54/64 (84%) did not have a trained physician anaesthetist and 5/64 (8%) had no trained providers for anaesthesia at all. Frequent shortages of drugs were reported for regional/neuroaxial anaesthesia, and other essential drugs were often lacking such as antacids and antihypertensives. We noted that many of the anaesthesia machines present were obsolete models without functional safety alarms and/or mechanical ventilators. Continuous ECG was only available in 3/64 (5%) of hospitals. CONCLUSION: We conclude that there is a significant lack of essential equipment for the delivery of safe anaesthesia across this region. This is compounded by the shortage of trained providers and inadequate supervision. It is therefore essential to strengthen anaesthesia services by addressing these specific deficiencies. This will include improved training of associate clinicians, training more physician anaesthetists and providing the basic equipment required to provide safe and effective care. These services are key components of comprehensive emergency obstetric care and anaesthetists are crucial in managing critically ill mothers and ensuring good surgical outcomes.

Challenges of Anesthesia in Low- and Middle-Income Countries: A Cross-Sectional Survey of Access to Safe Obstetric Anesthesia in East Africa.

BACKGROUND: The United Nations 2015 Millennium Development Goals targeted a 75% reduction in maternal mortality. However, in spite of this goal, the number of maternal deaths per 100,000 live births remains unacceptably high across Sub-Saharan Africa. Because many of these deaths could likely be averted with access to safe surgery, including cesarean delivery, we set out to assess the capacity to provide safe anesthetic care for mothers in the main referral hospitals in East Africa. METHODS: A cross-sectional survey was conducted at 5 main referral hospitals in East Africa: Uganda, Kenya, Tanzania, Rwanda, and Burundi. Using a questionnaire based on the World Federation of the Societies of Anesthesiologists (WFSA) international guidelines for safe anesthesia, we interviewed anesthetists in these hospitals, key informants from the Ministry of Health and National Anesthesia Society of each country (Supplemental Digital Content, http://links.lww.com/AA/B561). RESULTS: Using the WFSA checklist as a guide, none of respondents had all the necessary requirements available to provide safe obstetric anesthesia, and only 7% reported adequate anesthesia staffing. Availability of monitors was limited, and those that were available were often nonfunctional. The paucity of local protocols, and lack of intensive care unit services, also contributed significantly to poor maternal outcomes. For a population of 142.9 million in the East African community, there were only 237 anesthesiologists, with a workforce density of 0.08 in Uganda, 0.39 in Kenya, 0.05 in Tanzania, 0.13 in Rwanda, and 0.02 anesthesiologists in Burundi per 100,000 population in each country. CONCLUSIONS: We identified significant shortages of both the personnel and equipment needed to provide safe anesthetic care for obstetric surgical cases across East Africa. There is a need to increase the number of physician anesthetists, to improve the training of nonphysician anesthesia providers, and to develop management protocols for obstetric patients requiring anesthesia. This will strengthen health systems and improve surgical outcomes in developing countries. More funding is required for training physician anesthetists if developing countries are to reach the targeted specialist workforce density of the Lancet Commission on Global Surgery of 20 surgical, anesthetic, and obstetric physicians per 100,000 population by 2030.

Working towards safer surgery in Africa; a survey of utilization of the WHO safe surgical checklist at the main referral hospitals in East Africa.

BACKGROUND: Mortality from anaesthesia and surgery in many countries in Sub-Saharan Africa remain at levels last seen in high-income countries 70 years ago. With many factors contributing to these poor outcomes, the World Health Organization (WHO) launched the "Safe Surgery Saves Lives" campaign in 2007. This program included the design and implementation of the "Surgical Safety Checklist", incorporating ten essential objectives for safe surgery. We set out to determine the knowledge of and attitudes towards the use of the WHO checklist for surgical patients in national referral hospitals in East Africa. METHODS: A cross-sectional survey was conducted at the main referral hospitals in Mulago (Uganda), Kenyatta (Kenya), Muhimbili (Tanzania), Centre Hospitalier Universitaire de Kigali (Rwanda) and Centre Hospitalo-Universitaire de Kamenge (Burundi). Using a pre-set questionnaire, we interviewed anaesthetists on their knowledge and attitudes towards use of the WHO surgical checklist. RESULTS: Of the 85 anaesthetists interviewed, only 25 % regularly used the WHO surgical checklist. None of the anaesthetists in Mulago (Uganda) or Centre Hospitalo-Universitaire de Kamenge (Burundi) used the checklist, mainly because it was not available, in contrast with Muhimbili (Tanzania), Kenyatta (Kenya), and Centre Hospitalier Universitaire de Kigali (Rwanda), where 65 %, 19 % and 36 %, respectively, used the checklist. CONCLUSION: Adherence to aspects of care embedded in the checklist is associated with a reduction in postoperative complications. It is therefore necessary to make the surgical checklist available, to train the surgical team on its importance and to identify local anaesthetists to champion its implementation in East Africa. The Ministries of Health in the participating countries need to issue directives for the implementation of the WHO checklist in all hospitals that conduct surgery in order to improve surgical outcomes.

Factors influencing anesthesia residency selection: impact of global health opportunities.

PURPOSE: There is growing evidence to suggest that the current generation of medical students and young physicians is interested in global health. However, there are few data on the interest in global health by students pursuing a career in anesthesiology. The objective of this survey was to evaluate the importance of global health opportunities in regard to applicants' choice of anesthesiology residency programs. METHODS: Anesthesiology residency program directors in the United States were invited to distribute an online survey to recently matched residents. To reduce study bias, the survey included a wide selection of reasons for program choices in addition to global health. Participants were asked to rate independently, on a scale of 1 to 10 (1 = least important, 10 = most important), the importance that each factor had on their selection of an anesthesiology residency program. RESULTS: Of the 117 U.S. anesthesiology programs contacted, 87 (74%) distributed the survey. Completed surveys were obtained from 582 of 1,092 (53%) polled participants. All factors assessed were rated between 5 and 9 and the global health median [interquartile range] rating was 6 [3-7]. Nearly half of the survey respondents were interested in incorporating global health into future careers. More than three-quarters reported being interested in participating in, or reading about, global health activities during their residency. Responders with previous global health experience, or who were interested in an "in-country" experience, were more likely to choose programs that had global health opportunities available during residency. CONCLUSIONS: Anesthesia residency program applicants are interested in global health. Having a global health opportunity was an important reason for choosing a residency program, comparable to some more traditional factors. Regardless of previous global health experience, the majority of future anesthesia residents are either planning or considering participation in global health activities during or after training.

Research in surgery and anesthesia: challenges for post-graduate trainees in Uganda.

BACKGROUND: Research is critical to the training and practice of surgery and anesthesia in all settings, regardless of available resources. Unfortunately, the output of surgical and perioperative research from Africa is low. Makerere University College of Health Sciences' (MakCHS) surgical and anesthesia trainees are required to conduct research, though few publish findings or go on to pursue careers that incorporate research. We believe that early career experiences with research may greatly influence physicians' future conduct and utilization of research. We therefore sought to analyze trainee experiences and perceptions of research to identify interventions that could increase production of high-quality, locally led, surgical disease research in our resource-constrained setting. METHODS: Following ethical approval, a descriptive, cross-sectional survey was conducted among anesthesia and surgery trainees using a pretested, self-administered questionnaire. Data were tabulated and frequency tables generated. RESULTS: Of the 43 eligible trainees, 33 (77%) responded. Ninety-four percent identify research as important to career development, and 85% intend to publish their dissertations. The research dissertation is considered a financial burden by 64%. Also, 49% reported that their departments place low value on their research, and few of the findings are utilized. Trainees report that lack of protected research time, difficulty in finding research topics, and inadequate mentorship are the main challenges to conducting research projects. DISCUSSION: Our anesthesia and surgery trainees spend considerable resources on research endeavors. Most have significant interest in incorporating research into their careers, and most intend to publish their work in peer-reviewed journals. Here we identify several challenges facing trainees including research project development, financing and mentorship. We hope to use these results to improve support in these areas for our trainees and those in other resource-limited areas.

Comparison between continuous non-invasive estimated cardiac output by pulse wave transit time and thermodilution method.

AIMS AND OBJECTIVES: Cardiac output (CO) measurement is essential for many therapeutic decisions in anesthesia and critical care. Most available non-invasive CO measuring methods have an invasive component. We investigate "pulse wave transit time" (estimated continuous cardiac output [esCCO]) a method of CO measurement that has no invasive component to its use. MATERIALS AND METHODS: After institutional ethical committee approval, 14 adult (21-85 years) patients undergoing surgery and requiring pulmonary artery catheter (PAC) for measuring CO, were included. Postoperatively CO readings were taken simultaneously with thermodilution (TD) via PAC and esCCO, whenever a change in CO was expected due to therapeutic interventions. Both monitoring methods were continued until patients' discharge from the Intensive Care Unit and observer recording values using TD method was blinded to values measured by esCCO system. RESULTS: Three hundred and one readings were obtained simultaneously from both methods. Correlation and concordance between the two methods was derived using Bland-Altman analysis. Measured values showed significant correlation between esCCO and TD ( r = 0.6, P < 0.001, 95% confidence limits of 0.51-0.68). Mean and (standard deviation) for bias and precision were 0.13 (2.27) L/min and 6.56 (2.19) L/min, respectively. The 95% confidence interval for bias was - 4.32 to 4.58 L/min and for precision 2.27 to10.85 L/min. CONCLUSIONS: Although, esCCO is the only true non-invasive continuous CO monitor available and even though its values change proportionately to TD method (gold standard) with the present degree of error its utility for clinical/therapeutic decision-making is questionable.

Evaluating international global health collaborations: perspectives from surgery and anesthesia trainees in Uganda.

BACKGROUND: The number of international academic partnerships and global health programs is expanding rapidly worldwide. Although the benefits of such programs to visiting international partners have been well documented, the perceived impacts on host institutions in resource-limited settings have not been assessed adequately. We sought to describe the perspectives of postgraduate, Ugandan trainees toward international collaborations and to discuss how these perceptions can be used to increase the positive impact of international collaborations for the host institution. METHODS: We conducted a descriptive, cross-sectional survey among anesthesia and surgery trainees at Makerere College of Health Sciences (Kampala, Uganda) using a pretested, self-administered questionnaire. Data were summarized as means or medians where applicable; otherwise, descriptive statistical analyses were performed. RESULTS: Of 43 eligible trainees, 77% completed the questionnaire. The majority (75%) agreed that visiting groups improve their training, mostly through skills workshops and specialist camps. A substantial portion of trainees reported that international groups had a neutral or negative impact on patient care (40%). Only 15% agreed that research projects conducted by international groups are in priority areas for Uganda. Among those surveyed, 28% reported participation in these projects, but none has published as a coauthor. Nearly one-third of trainees (31%) reported discomfort with the ethics of some clinical decisions made by visiting faculty. CONCLUSION: The current perspective from the surgery and anesthesia trainees of Makerere College of Health Sciences demonstrates rich ground for leveraging international collaborations to improve training, primarily through skills workshops, specialist camps, and more visiting faculty involvement. This survey also identified potential challenges in collaborative research and ethical dilemmas that warrant further examination.

Teaching surgical skills using video internet communication in a resource-limited setting.

OBJECTIVE: To study the feasibility and acceptability of using video Internet communication to teach and evaluate surgical skills in a low-resource setting. METHODS: This case-controlled study used video Internet communication for surgical skills teaching and evaluation. We randomized intern physicians rotating in the Obstetrics and Gynecology Department at Mulago Hospital at Makerere University in Kampala, Uganda, to the control arm (usual practice) or intervention arm (three video teaching sessions with University of California, San Francisco faculty). We made preintervention and postintervention videos of all interns tying knots using a small video camera and uploaded the files to a file hosting service that offers cloud storage. A blinded faculty member graded all of the videos. Both groups completed a survey at the end of the study. RESULTS: We randomized 18 interns with complete data for eight in the intervention group and seven in the control group. We found score improvement of 50% or more in six of eight (75%) interns in the intervention group compared with one of seven (14%) in the control group (P=.04). Scores declined in five of the seven (71%) controls but in none in the intervention group. Both intervention and control groups used attendings, colleagues, and the Internet as sources for learning about knot-tying. The control group was less likely to practice knot-tying than the intervention group. The trainees and the instructors felt this method of training was enjoyable and helpful. CONCLUSION: Remote teaching in low-resource settings, where faculty time is limited and access to visiting faculty is sporadic, is feasible, effective, and well-accepted by both learner and teacher. LEVEL OF EVIDENCE: II.

Surgery and anesthesia capacity-building in resource-poor settings: description of an ongoing academic partnership in Uganda.

BACKGROUND: Surgery and perioperative care have been neglected in the arena of global health despite evidence of cost-effectiveness and the growing, substantial burden of surgical conditions. Various approaches to address the surgical disease crisis have been reported. This article describes the strategy of Global Partners in Anesthesia and Surgery (GPAS), an academically based, capacity-building collaboration between North American and Ugandan teaching institutions. METHODS: The collaboration's projects shift away from the trainee exchange, equipment donation, and clinical service delivery models. Instead, it focuses on three locally identified objectives to improve surgical and perioperative care capacity in Uganda: workforce expansion, research, collaboration. RESULTS: Recruitment programs from 2007 to 2011 helped increase the number of surgery and anesthesia trainees at Mulago Hospital (Kampala, Uganda) from 20 to 40 and 2 to 19, respectively. All sponsored trainees successfully graduated and remained in the region. Postgraduate academic positions were created and filled to promote workforce retention. A local research agenda was developed, more than 15 collaborative, peer-reviewed papers have been published, and the first competitive research grant for a principal investigator in the Department of Surgery at Mulago was obtained. A local projects coordinator position and an annual conference were created and jointly funded by partnering international efforts to promote collaboration. CONCLUSIONS: Sub-Saharan Africa has profound unmet needs in surgery and perioperative care. This academically based model helped increase recruitment of trainees, expanded local research, and strengthened stakeholder collaboration in Uganda. Further analysis is underway to determine the impact on surgical disease burden and other important outcome measures.

Developing a curriculum for anaesthesia training in low- and middle-income countries.

The shortage of healthcare providers in low- and middle-income countries (LMICs) is well documented and is manifested by a profound lack of anaesthesia providers, especially throughout Sub-Saharan Africa. The need to develop and support training programs for physician and non-physician anesthetists in LMICs is therefore paramount to providing safe and cost effective anaesthesia care. Development of these training programs is multifaceted and must take into account the specific needs of the recipient country in order to be successful. Curriculum development should be directed towards sustainable change, ultimately reducing the need for outside support. To ensure viability as the new program develops, graduates need to be assimilated into the program as leaders. Emphasis needs to be placed on lessons learnt, professional conduct, and improving outcomes. Anaesthesia educational programs must emphasize quality, safety and professionalism in the providers and the care they deliver. Region-specific teaching methods should be developed using problem-based learning techniques and presenting data in a way that educates rather than castigates. There are good examples of programs that have been implemented to support education in LMICs. However, there are only a few that have successfully adopted a holistic approach to the entire curriculum. More often than not, programs have focused on specific areas of expertise of visiting teachers, rather than the needs of the recipient program. Because of the limited data available, it remains difficult to define any one clear path to achieving these goals. A combination of coordination and collaboration will increase the efficacy of implementing new or upgrading existing programs and will allow clearly defined paths to be defined in the future.

Surgery in global health delivery.

Surgical conditions account for a significant portion of the global burden of disease and have a substantial impact on public health in low- and middle-income countries. This article reviews the significance of surgical conditions within the context of public health in these settings, and describes selected approaches to global surgery delivery in specific contexts. The discussion includes programs in global trauma care, surgical care in conflict and disaster, and anesthesia and perioperative care. Programs to develop surgical training in Botswana and pediatric surgery through international partnership are also described, with a final review of broader approaches to training for global surgical delivery. In each instance, innovative solutions, as well as lessons learned and reasons for program failure, are highlighted.

Global anesthesia workforce crisis: a preliminary survey revealing shortages contributing to undesirable outcomes and unsafe practices.

BACKGROUND: The burden of disease, disability, and mortality that could be averted by surgery is growing. However, few low and middle income countries (LMICs) have the infrastructure or capacity to provide surgical services to meet this growing need. Equally, few of these countries have been assessed for key infrastructural capacity including surgical and anesthesia providers, equipment, and supplies. These assessments are critical to revealing magnitude of the evolving surgical and anesthesia workforce crisis, related morbidity and mortality, and necessary steps to mitigate the impact of the crisis. METHODS: A pilot Internet-based survey was conducted to estimate per-capita anesthesia providers in LMICs. Information was obtained from e-mail respondents at national health care addresses, and from individuals working in-country on anesthesia-related projects. RESULTS: Workers from 6 of 98 countries responded to direct e-mail inquiries, and an additional five responses came from individuals who were working or had worked in-country at the time of the survey. The data collected revealed that the per-capita anesthesia provider ratio in the countries surveyed was often 100 times lower than in developed countries. CONCLUSIONS: This pilot study revealed that the number of anesthesia providers available per capita of population is markedly reduced in low and lower middle income countries compared to developed countries. As anesthesia providers are an integral part of the delivery of safe and effective surgical care, it is essential that more data is collected to fully understand the deficiencies in workforce and capacity in low and middle income countries.

The neglect of the global surgical workforce: experience and evidence from Uganda.

BACKGROUND: Africa's health workforce crisis has recently been emphasized by major international organizations. As a part of this discussion, it has become apparent that the workforce required to deliver surgical services has been significantly neglected. METHODS: This paper reviews some of the reasons for this relative neglect and emphasizes its importance to health systems and public health. We report the first comprehensive analysis of the surgical workforce in Uganda, identify challenges to workforce development, and evaluate current programs addressing these challenges. This was performed through a literature review, analysis of existing policies to improve surgical access, and pilot retrospective studies of surgical output and workforce in nine rural hospitals. RESULTS: Uganda has a shortage of surgical personnel in comparison to higher income countries, but the precise gap is unknown. The most significant challenges to workforce development include recruitment, training, retention, and infrastructure for service delivery. Curricular innovations, international collaborations, and development of research capacity are some of the initiatives underway to overcome these challenges. Several programs and policies are addressing the maldistribution of the surgical workforce in urban areas. These programs include surgical camps, specialist outreach, and decentralization of surgical services. Each has the advantage of improving access to care, but sustainability has been an issue for all of these programs. Initial results from nine hospitals show that surgical output is similar to previous studies and lags far behind estimates in higher-income countries. Task-shifting to non-physician surgical personnel is one possible future alternative. CONCLUSIONS: The experience of Uganda is representative of other low-income countries and may provide valuable lessons. Greater attention must be paid to this critical aspect of the global crisis in human resources for health.

Pulmonary artery pressure in healthy subjects at 4250 m measured by Doppler echocardiography.

OBJECTIVE: Acute hypoxia causes vasoconstriction in the pulmonary arteries. This hypoxic pulmonary vasoconstriction (HPV) has been reported to be common in subjects exposed to high altitude. In the past, it has been difficult to directly measure this HPV because of the invasive nature of tests, but the recent availability of portable color flow Doppler ultrasound has enabled measurements of pulmonary artery systolic pressure (PASP) in the field. We set out to study the feasibility of this method to detect changes related to HPV at 4250 m. We hypothesized that significant changes in the cardiopulmonary circulation are seen at high altitude and are detectable with Doppler echocardiography. In addition, we hypothesized that detected changes are related to the syndrome of acute mountain sickness (AMS) and could be reversed using 100% oxygen. METHODS: Over a 10-week period in the spring of 1998, 56 healthy lowlanders not normally residing at altitude were studied while visiting 4250 m in Nepal having walked from 2774 m. This was a cross-sectional observational study conducted by a single experienced observer at high altitude, using transthoracic color flow continuous wave Doppler echocardiography. Subjects were initially assessed for significant tricuspid regurgitation (TR) to measure PASP. After estimating PASP under ambient conditions at altitude, oxygen was delivered and PASP remeasured. RESULTS: Of 56 subjects, 36 had Doppler signals appropriate for estimation of pulmonary artery systolic pressure. In these 36, a wide range of PASP was observed (mean 25 mm Hg, range 18-36 mm Hg), but none fell outside of the normal range. After oxygen administration, PASP was reduced (from mean 25 mm Hg to mean 18 mm Hg, P<.0001) suggesting that a degree of hypoxic pulmonary vasoconstriction was present. No subjects in the study group reported clinical AMS. CONCLUSIONS: We found PASP at 4250 m to be within the normal range but higher than would be expected at sea level; however, unlike previous reports, we found such increases to be mild and reversible with oxygen. In addition, the observed incidence of AMS was low when compared with earlier studies, perhaps related to adequate acclimatization.

Adaptation to altitude as a vehicle for experiential learning of physiology by university undergraduates.

In this article, an experiential learning activity is described in which 19 university undergraduates made experimental observations on each other to explore physiological adaptations to high altitude. Following 2 wk of didactic sessions and baseline data collection at sea level, the group ascended to a research station at 12,500-ft elevation. Here, teams of three to four students measured the maximal rate of oxygen uptake, cognitive function, hand and foot volume changes, reticulocyte count and hematocrit, urinary pH and 24-h urine volume, athletic performance, and nocturnal blood oxygen saturation. Their data allowed the students to quantify the effect of altitude on the oxygen cascade and to demonstrate the following altitude-related changes: 1) impaired performance on selected cognitive function tests, 2) mild peripheral edema, 3) rapid reticulocytosis, 4) urinary alkalinization and diuresis, 5) impaired aerobic but not anaerobic exercise performance, 6) inverse relationship between blood oxygen saturation and resting heart rate, and 7) regular periodic nocturnal oxygen desaturation events accompanied by heart rate accelerations. The students learned and applied basic statistical techniques to analyze their data, and each team summarized its results in the format of a scientific paper. The students were uniformly enthusiastic about the use of self-directed experimentation to explore the physiology of altitude adaptation and felt that they learned more from this course format than a control group of students felt that they learned from a physiology course taught by the same instructor in the standard classroom/laboratory format.
