Surgical education at Weill Bugando Medical Centre: supplementing surgical training and investing in local health care providers

Global surgery initiatives increasingly are focused on strengthening education and local health care systems to build surgical capacity. The goal of this education project was to support local health care providers in augmenting the surgical curriculum at a new medical school, thus promoting long-term local goals and involvement. Working with local surgeons, residents, and medical and assistant medical officer students, we identified the most common surgical conditions presenting to Weill Bugando Medical Centre in Mwanza, Tanzania, and the areas of greatest need in surgical education. We developed an 8-week teaching schedule for undergraduate students and an electronic database of clinical surgery topics. In addition, we started teaching basic surgical skills in the operating theatre, bridging to an official and recurring workshop through a supporting international surgery organization. The medical and assistant medical officer students reported increased satisfaction with their clinical surgery rotations and mastery of key educational subjects. The initiation of an Essential Surgical Skills workshop through the Canadian Network for International Surgery showed students had improved comfort with basic surgical techniques. Short-term surgical missions may appear to fill a void in the shortage of health care in the developing world. However, we conclude that global health resources are more appropriately used through projects giving ownership to local providers and promoting education as a foundation of development. This results in better coordination among local and visiting providers and greater impact on education and long-term growth of health care capacity.Les initiatives internationales en ce qui concerne la chirurgie sont de plus en plus axées sur le renforcement des programmes de formation et des systèmes de soins de santé locaux pour consolider les capacités dans ce domaine. L’objectif de ce projet éducatif était d’aider les professionnels de la santé locaux à enrichir le programme de chirurgie d’une nouvelle faculté de médecine et de favoriser ainsi l’atteinte des objectifs et une meilleure participation à long terme à l’échelle locale. En travaillant avec des chirurgiens, des résidents, des étudiants en médecine et de futurs aides-médecins locaux, nous avons recensé les chirurgies les plus fréquentes au Centre médical Weill Bugando à Mwanza à la Tanzanie, et les domaines de la chirurgie où les besoins de formation sont les plus grands. Nous avons mis sur pied un calendrier d’enseignement échelonné sur 8 semaines pour les étudiants et une base de données électronique sur les différents types de chirurgie clinique. Nous avons également commencé à enseigner les techniques chirurgicales de base au bloc opératoire, en parallèle avec un atelier officiel récurrent, grâce au soutien d’une association internationale de chirurgie. Les étudiants en médecine et les futurs aides-médecins se sont dits plus satisfaits de leur stage de chirurgie clinique et de leur maîtrise des principaux enjeux didactiques. Le lancement d’un atelier sur les compétences chirurgicales de base, rendu possible grâce au Réseau canadien pour la chirurgie internationale, a montré que les étudiants se sentent plus à l’aise avec les techniques chirurgicales de base. Les missions chirurgicales de courte durée peuvent sembler combler une lacune dans les pays en développement où les soins de santé sont insuffisants. Toutefois, nous concluons que les ressources en santé internationale sont utilisées de manière plus appropriée dans le cadre de projets qui responsabilisent les fournisseurs de soins locaux et favorisent leur formation comme base du développement. Cela donne lieu à une meilleure coordination entre les professionnels locaux et les coopérants et exerce un impact plus grand sur la formation et la croissance des capacités en matière de soins de santé à long terme.International volunteerism has a long-standing history among surgeons, particularly those with academic affiliations and relationships with departments of global health. With growing recognition of World Health Organization (WHO) projections that surgical diseases will represent a substantial global health burden by 2030,¹ and with current data showing that 90% of deaths from injuries occur in developing countries,² this interest in surgical volunteerism has increased steadily in recent years.³Many attempts to ameliorate the disparities in worldwide surgical care have been focused on short-term medical missions. However, these missions arguably undermine the local health care systems and disrupt relationships among physicians and their patients.⁴ This mode of service delivery is unsustainable, perpetuating a cycle of externally imposed and often uncoordinated “solutions” that fail to offer systematic education and infrastructural development based on local goals.In an effort to develop a sustainable global surgery relationship that will provide long-term support and engender self-reliance among local surgeons, Weill Cornell Medical College has established a relationship with the newly founded Weill Bugando University College of Health Sciences (Weill BUCHS) in Mwanza, Tanzania. Working with both Weill BUCHS and the existing Bugando Medical Centre (BMC), the project involves assisting with improving and organizing the existing surgical curriculum for undergraduate medical students, emphasizing scheduled bedside teaching, and providing training in basic surgical procedures and surgical subspecialty techniques for residents and attending surgeons in neurosurgery. It also includes the addition of the Canadian Network for International Surgery (CNIS) Essential Surgical Skills (ESS) workshop for all final-year medical students, which aims to improve student skills on a defined set of basic surgical procedures.Unlike other missions or surgical electives in which Western surgeons travel for brief periods of time to developing countries with the purpose of performing large volumes of surgical cases, the emphasis of involvement with Weill BUCHS is to assist in the training and education of physicians to create independent and sustainable medical care. Weill Cornell has worked with Weill BUCHS surgeons to provide instruction on didactic topics and basic surgical skills and to schedule recurring visits by Weill Cornell surgical faculty and residents for teaching purposes.This development of Weill BUCHS grew from recognition that Tanzania suffers from a dearth of physicians, with only 0.1 physicians per 10 000 population — one of the lowest physician:patient ratios in the world.⁵ In addition, the health work force in Tanzania is unevenly distributed, with only one-third of doctors practising in the rural areas where three-quarters of the population resides.     

A Team-Based Approach to Introduce and Sustain the Use of the WHO Surgical Safety Checklist in Tanzania

Introduction

Millions of patients worldwide suffer disability and death due to complications related to surgery. Many of these complications can be reduced by the use of the World Health Organization (WHO) Surgical Safety Checklist (SSC), a simple tool that can enhance teamwork and communication and improve patient safety. Despite the evidence on benefits of its use, introducing and sustaining the use of the checklist are challenging. We present a team-based approach employed in a low-resource setting in Tanzania, which resulted in high checklist utilization and compliance rates.

Methods

We reviewed reported data from facility registers supplemented by direct observation data by mentors to evaluate the use of the WHO SSC across 40 health facilities in two regions of Tanzania between January and December 2018. We analyzed the self-reported monthly data on total number of major surgeries performed and proportion of surgeries where the checklist was used. We also analyzed the use of the SSC during direct observation by external mentors and completion rates of the SSC in a random selection of patient files during two mentorship visits between June and December 2018.

Results

During the review period, the average self-reported checklist utilization rate was 79.3% (11,564 out of 14,580 major surgeries). SSC utilization increased from 0% at baseline in January 2018 to 98% in December 2018. The proportion of checklists that were completely and correctly filled out increased between the two mentor visits from 82.1 to 92.8%, but the gain was significantly greater at health centers than at hospitals (p < 0.05). Health centers (which had one or two surgical teams) self-reported a higher checklist utilization rate than hospitals (which had multiple surgical teams), i.e., 99.4% vs 68.8% (p < 0.05).

Conclusion and recommendations

Our findings suggest that Surgical Safety Checklist implementation is feasible even in lower-resource settings. The self-reported SSC utilization rate is higher than reported in other similar settings. We attribute this finding to the team-based approach employed and the ongoing regular mentorship. We recommend use of this approach to scale-up checklist use in other regions in the country as recommended in the Ministry of Health of Tanzania’s National Surgical, Obstetric, and Anesthesia Plan (NSOAP).

     

Comparison of intracranial pressure measured in the cerebral cortex and the cerebellum of the rat

In this study, we evaluated the accuracy of intracranial pressure (ICP) measurement in rats by insertion of a miniature ICP probe in the parenchyma of the cerebellum. A comparison was made between the ICP values measured simultaneously in the parenchyma of the cerebral cortex and the cerebellum. In order to obtain a wide range of ICP, animals were subjected to a severe closed head injury (CHI), a moderate CHI or to a sham operation. ICP values ranged from 0.8 to 43.9 mmHg. After 15 min stabilisation the first measurement was taken and followed by a second measurement 25 min after onset to allow comparison of ICP changes at the two implantation sites. Linear regression analysis showed a highly significant correlation at 15 min: Y = 0.919X + 0.655 (R(2) = 0.977), and at 25 min: Y = 0.931X + 0.698 (R(2) = 0.976). The differences in ICP measurement between cerebellar and cerebral site were not significantly different from zero at both time points. Altman-Bland plots showed that the difference in ICP readings between the two locations could differ maximally by 5.3 mmHg. The largest differences were detected when high ICP values were recorded. We conclude that in rats the ICP measurement in the cerebellum is comparable to the ICP measurement in the cerebral cortex. The cerebellar ICP can be used as a valuable alternative during experimental procedures.     

Pentobarbital fails to reduce cerebral oxygen consumption early after non-hemorrhagic closed head injury in rats

It is unknown whether barbiturates suppress cerebral oxygen metabolism after cerebral trauma as they do in normal individuals. We evaluated the influence of pentobarbital on cerebral oxygen handling of normal rats and rats subjected to non-hemorrhagic closed head injury (CHI). Oxygen delivery was assessed by measuring cerebral perfusion and oxygen extraction, enabling the calculation of cerebral metabolic rate of oxygen (CMRO2). Mitochondrial function was assessed by studying changes in the oxidized cytochrome oxidase concentration. CHI caused changes in both systemic and cerebral hemodynamics. Cerebral blood flow was reduced to 66% of its control value, but the cerebral metabolic rate of oxygen remained unchanged. Pentobarbital administration induced a significant lowering of the cerebral oxygen consumption in normal rats associated with a secondary decrease in cerebral perfusion. In rats subjected to CHI, pentobarbital was unable to lower the cerebral metabolic demand and did not cause a further decrease in perfusion. Pentobarbital was unable to significantly modulate mitochondrial function in traumatized rats, whereas it exerted this effect in all control animals. We therefore conclude that, in rats subjected to CHI, pentobarbital is unable to perform its beneficial effects on the cerebral metabolism.     

Schistosomal peritonitis secondary to perforated appendicitis

In Tanzania, Schistosoma mansoni is endemic and causes intestinal schistosomiasis which affects various internal organs. However, worldwide there have been very few reports of cases of peritonitis due to schistosomal appendicitis. Here we report a rare case of schistosomal appendicitis with peritonitis in a 33 year-old male patient who recovered quickly after surgery.     

Distribution of causes of maternal mortality among different socio-demographic groups in Ghana; a descriptive study

Background  

Ghana's maternal mortality ratio remains high despite efforts made to meet Millennium Development Goal 5. A number of studies have been conducted on maternal mortality in Ghana; however, little is known about how the causes of maternal mortality are distributed in different socio-demographic subgroups. Therefore the aim of this study was to assess and analyse the causes of maternal mortality according to socio-demographic factors in Ghana.
