Global Surgery 2030: a roadmap for high income country actors

The Millennium Development Goals have ended and the Sustainable Development Goals have begun, marking a shift in the global health landscape. The frame of reference has changed from a focus on 8 development priorities to an expansive set of 17 interrelated goals intended to improve the well-being of all people. In this time of change, several groups, including the Lancet Commission on Global Surgery, have brought a critical problem to the fore: 5 billion people lack access to safe, affordable surgical and anaesthesia care when needed. The magnitude of this problem and the worlds new focus on strengthening health systems mandate reimagined roles for and renewed commitments from high income country actors in global surgery. To discuss the way forward, on 6 May 2015, the Commission held its North American launch event in Boston, Massachusetts. Panels of experts outlined the current state of knowledge and agreed on the roles of surgical colleges and academic medical centres; trainees and training programmes; academia; global health funders; the biomedical devices industry, and news media and advocacy organisations in building sustainable, resilient surgical systems. This paper summarises these discussions and serves as a consensus statement providing practical advice to these groups. It traces a common policy agenda between major actors and provides a roadmap for maximising benefit to surgical patients worldwide. To close the access gap by 2030, individuals and organisations must work collectively, interprofessionally and globally. High income country actors must abandon colonial narratives and work alongside low and middle income country partners to build the surgical systems of the future.

Vitamin D deficiency does not increase the rate of postoperative hypocalcemia after thyroidectomy

BACKGROUND Hypocalcemia is a frequent complication of thyroidectomy. Although typically mild and temporary, it can lead to an increased length of stay, readmission, and in some cases be permanent. Controversy exists as to whether vitamin D deficiency (VDD) contributes to post-thyroidectomy hypocalcemia. METHODS This is a retrospective study of 152 patients who underwent thyroidectomy. Patients with or without VDD were compared. Data were analyzed for demographics, operative procedure, calcium levels, and complications of hypocalcemia. RESULTS There was no difference in the rates of biochemical or symptomatic hypocalcemia or in the need for readmission between the VDD and non-VDD groups. A multivariate analysis controlling for central neck dissection, parathyroid autotransplant, and preoperative diagnosis confirmed no association between VDD and post-thyroidectomy hypocalcemia. CONCLUSIONS Despite VDD being common in patients undergoing thyroidectomy, our results do not suggest that this increases the rate of hypocalcemia. Thus, preoperative evaluation/repletion of VDD is unlikely to reduce post-thyroidectomy hypocalcemia rates.

Contextual Challenges to Safe Surgery in a Resource-limited Setting: A Multicenter, Multiprofessional Qualitative Study

Objectives: Safe surgery should be available to all patients, no matter the setting. The purpose of this study was to explore the contextual-specific challenges to safe surgical care encountered by surgeons and surgical teams in many in low- and middle-income countries (LMICs), and to understand the ways in which surgical teams overcome them. Background: Optimal surgical performance is highly complex and requires providers to integrate and communicate information regarding the patient, task, team, and environment to coordinate team-based care that is timely, effective, and safe. Resource limitations common to many LMICs present unique challenges to surgeons operating in these environments, but have never been formally described. Methods: Using a grounded theory approach, we interviewed 34 experienced providers (surgeons, anesthetists, and nurses) at the 4 tertiary referral centers in Rwanda, to understand the challenges to safe surgical care and strategies to overcome them. Interview transcripts were coded line-by-line and iteratively analyzed for emerging themes until thematic saturation was reached. Results: Rwandan-described challenges related to 4 domains: physical resources, human resources, overall systems support, and communication/language. The majority of these challenges arose from significant variability in either the quantity or quality of these domains. Surgical providers exhibited examples of resilient strategies to anticipate, monitor, respond to, and learn from these challenges. Conclusions: Resource variability rather than lack of resources underlies many contextual challenges to safe surgical care in a LMIC setting. Understanding these challenges and resilient strategies to overcome them is critical for both LMIC surgical providers and surgeons from HICs working in similar settings.

Quality of essential surgical care in low- and middle-income countries: a systematic review of the literature

PURPOSE Quality of care is an emerging area of focus in the surgical disciplines. However, much of the emphasis on quality is limited to high-income countries. To address this gap, we conducted a systematic review of the literature on the quality of essential surgical care in low- and middle- income countries (LMIC). DATA SOURCES We searched PubMed, Cinahl, Embase and CAB Abstracts using three domains: quality of care, surgery and LMIC. STUDY SELECTION We limited our review to studies of essential surgeries that pertained to all three search domains. DATA EXTRACTION We extracted data on study characteristics, type of surgery and the way in which quality was studied. RESULTS OF DATA SYNTHESIS 354 studies were included. 281 (79.4%) were single-center studies and nearly half (n = 169, 46.9%) did not specify the level of facility. 207 studies reported on mortality (58.47%) and 325 reported on a morbidity (91.81%), most commonly surgical site infection (n = 190, 53.67%). Of the Institute of Medicine domains of quality, studies were most commonly of safety (n = 310, 87.57%) and effectiveness (n = 180, 50.85%) and least commonly of equity (n = 21, 5.93%). CONCLUSION We find that while there are numerous studies that report on some aspects of quality of care, much of the data is single center and observational. Additionally, there is variability on which outcomes are reported both within and across specialties. Finally, we find under-reporting of parameters of equity and timeliness, which may be critical areas for research moving forward.

The Economic Case for Surgical Care in Low-Resource Settings

Research over the past 15 years has dramatically changed how surgical care is viewed within global health. Once thought as too expensive and inappropriate for settings of limited resources, surgical care is now recognized as an essential component of strong health systems and capable of treating a wide spectrum of important clinical problems in a highly cost-effective manner. More so, the economic losses from untreated surgical conditions far exceed any expenditure that would be required to scale-up surgical care—making surgical care an attractive investment for promoting economic growth in low- and middle-income countries (LMICs). In this chapter, we trace the remarkable transformation in thinking that has occurred around the economic issues of surgical care in settings of limited resources. To do so, we provide a brief overview of global economic development and its relationship to health, review the economic case for surgical care in LMICs, and conclude with a discussion of financing of surgical care in the era of new Sustainable Development Goals. With efforts already underway to scale-up surgical care in some countries, the economics of surgical care will continue to be one of the most important topics in global surgery.

Improving Surgical Safety and Nontechnical Skills in Variable-Resource Contexts: A Novel Educational Curriculum.

OBJECTIVE A substantial proportion of adverse intraoperative events are attributed to failures in nontechnical skills. To strengthen these skills and improve surgical safety, the Non-Technical Skills for Surgeons (NOTSS) taxonomy was developed as a common framework. The NOTSS taxonomy was adapted for low- and middle-income countries, where variable resources pose a significant challenge to safe surgery. The NOTSS for variable-resource contexts (VRC) curriculum was developed and implemented in Rwanda, with the aim of enhancing knowledge and attitudes about nontechnical skills and promoting surgical safety. DESIGN The NOTSS-VRC curriculum was developed through a rigorous process of integrating contextually appropriate values. It was implemented as a 1-day training course for surgical and anesthesia postgraduate trainees. The curriculum comprises lectures, videos, and group discussions. A pretraining and posttraining questionnaire was administered to compare knowledge and attitudes regarding nontechnical skills, and their potential to improve surgical safety. SETTING The setting of this study was in the tertiary teaching hospital of Kigali, Rwanda. PARTICIPANTS Participants were residents of the University of Kigali. A total of 55 residents participated from general surgery (31.4%), obstetrics (25.5%), anesthesia (17.6%), and other surgical specialties (25.5%). RESULTS In a paired analysis, understanding of NOTSS improved significantly (55.6% precourse, 80.9% postcourse, p<0.01). All residents reported that the course would improve their ability to provide safer patient care, and 97.4% believed developing nontechnical skills would improve patient outcomes. CONCLUSIONS Nontechnical skills must be highlighted in surgical training in low- and middle-income countries. The NOTSS-VRC curriculum can be implemented without additional technology or significant financial cost. Its deliberate design for resource-constrained settings allows it to be used both as an educational course and a quality improvement strategy. Our research demonstrates it is feasible to improve knowledge and attitudes about NOTSS through a 1-day course, and represents a novel approach to improving global surgical safety.

Using Touch Surgery to Improve Surgical Education in Low- and Middle-Income Settings: A Randomized Control Trial.

BACKGROUND/OBJECTIVE There is a severe surgical workforce shortage in Rwanda. Innovative educational tools must be introduced to train more residents and increase surgical capacity. Touch Surgery (TS) is a smartphone application that offers trainees the opportunity to practice operations; however, its effect is unknown in low- and middle-income countries. Our objectives were to determine the training effect of TS and its feasibility for use in surgery education in a low-resource setting. DESIGN We performed a randomized control trial of University of Rwanda surgical residents. Participants were blocked by postgraduate year and randomized to textbook or TS for learning tendon repair surgical technique. After the learning period, participants performed a tendon repair simulation, evaluated by blinded expert raters. Presimulation and postsimulation questionnaires tested their knowledge of tendon repair. SETTING The study was conducted at the simulation center of the University Teaching Hospital of Kigali, a tertiary referral and teaching hospital. PARTICIPANTS The study included University of Rwanda surgery residents. A total 27 of 51 surgery residents (52.94%) were enrolled. Participating residents represented the following specialties: general surgery (51.85%), orthopedics (40.74%), and urology (7.41%). RESULTS TS users scored 89.7% on tendon repair simulation, compared to textbook users who scored 63.4% (p < 0.001). Postsimulation questionnaires showed a significant improvement in cognitive scores for TS users (38.6%, p < 0.001), as compared to nonsignificant improvement for textbook users (15.9%, p = 0.304). About 92.3% of TS users reported that TS represents a useful training tool, and 61.5% reported that it would be a good or very good required part of the curriculum. CONCLUSIONS TS is a useful tool to improve both technical skills and knowledge of tendon repair procedure steps; however, its role may be limited to a supplemental tool as it does not improve the theoretical knowledge. TS has the potential to be implemented in a surgical academic curriculum in low- and middle-income countries.

A qualitative study on perceptions of surgical careers in Rwanda: A gender-based approach

Access to surgical care in low- and middle-income countries (LMICs) remains deficient without an adequate workforce. There is limited understanding of the gender gap in surgical trainees in LMICs. In Rwanda, females fill only one of 20 positions available. Understanding surgeons’ experiences and perceptions of surgical careers may help facilitate support for females to contribute to the global surgical workforce. We performed qualitative analysis on perceptions of surgical careers through semi-structured interviews of all female surgeons (n = 6) and corresponding male surgeons (n = 6) who are training or have trained at University of Rwanda. Transcripts were analyzed with code structure formed through an integrated approach. Question categories formed the deductive framework, while theoretical saturation was reached through inductive grounded theory. Themes were organized within two key points of the career timeline. First, for developing interest in surgery, three main themes were identified: role models, patient case encounters, and exposure to surgery. Second, for selecting and sustaining surgical careers, four main themes emerged: social expectations about roles within the family, physical and mental challenges, professional and personal support, and finances. All female surgeons emphasized gender assumptions and surgical working culture as obstacles, with a corresponding strong sense of self-confidence and internal motivation that drew them to select and maintain careers in surgery. Family, time, and physical endurance were cited as persistent challenges for female participants. Our study reveals concepts for further exploration about gendered perceptions of surgical careers. Efforts to improve support for female surgical careers as a strategy for shaping surgical work culture and professional development in Rwanda should be considered. Such strategies may be beneficial for improving the global surgical workforce.

The Colorado Humanitarian Surgical Skills Workshop: A Cadaver-Based Workshop to Prepare Residents for Surgery in Austere Settings

OBJECTIVE Interest in humanitarian surgery is high among surgical and obstetric residents. The Colorado Humanitarian Surgical Skills Workshop is an annual 2-day course exposing senior residents to surgical techniques essential in low- and middle-income countries but not traditionally taught in US residencies. We evaluated the courses ability to foster resident comfort, knowledge, and competence in these skills. DESIGN The cohort of course participants was studied prospectively. Participants attended didactic sessions followed by skills sessions using cadavers. Sample areas of focus included general surgery (mesh-free hernia repair), orthopedics (powerless external fixation), and neurosurgery (powerless craniotomy). Before and after the course, participants answered a questionnaire assessing confidence with taught skills; took a knowledge-based test composed of multiple choice and open-ended questions; and participated in a manual skills test of tibial external fixation. SETTING The Center for Surgical Innovation, University of Colorado School of Medicine. PARTICIPANTS A total of 12 residents (11 general surgical and 1 obstetric) from ten US institutions. RESULTS After the course, participants perceived increased confidence in performing all 27 taught procedures and ability to practice in low- and middle-income countries. In knowledge-based testing, 10 of 12 residents demonstrated improvement on multiple choice questioning and 9 of 12 residents demonstrated improvement on open-ended questioning with structured scoring. In manual skills testing, all external fixator constructs demonstrated objective improvement on structured scoring and subjective improvement on stability assessment. CONCLUSIONS For senior residents interested in humanitarian surgery, a combination of skills-focused teaching and manual practice led to self-perceived and objective improvement in relevant surgical knowledge and skills. The Colorado Humanitarian Surgical Skills Workshop represents an effective model for transmitting essential surgical principles and techniques of value in low-resource settings.

Using the Consolidated Framework for Implementation Research to implement and evaluate national surgical planning

The Lancet Commission on Global Surgery defined six surgical indicators and a framework for a national surgical plan that aimed to incorporate surgical care as a part of global public health. Multiple countries have since begun national surgical planning; each faces unique challenges in doing so. Implementation science can be used to more systematically explain this heterogeneous process, guide implementation efforts and ultimately evaluate progress. We describe our intervention using the Consolidated Framework for Implementation Research. This framework requires identifying characteristics of the intervention, the individuals involved, the inner and outer setting of the intervention, and finally describing implementation processes. By hosting a consultative symposium with clinicians and policy makers from around the world, we are able to specify key aspects of each element of this framework. We define our intervention as the incorporation of surgical care into public health planning, identify local champions as the key individuals involved, and describe elements of the inner and outer settings. Ultimately we describe top-down and bottom-up models that are distinct implementation processes. With the Consolidated Framework for Implementation Research, we are able to identify specific strategic models that can be used by implementers in various settings. While the integration of surgical care into public health throughout the world may seem like an insurmountable challenge, this work adds to a growing effort that seeks to find a way forward.
