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.

Objective: The aim of this study was to describe national trends and outcomes of in-hospital postoperative opioid overdose (OD) and identify predictors of postoperative OD. Summary of Background Data: In 2000, the Joint Commission recommended making pain the 5th vital sign, increasing the focus on postoperative pain control. However, the benefits of pain management must be weighed against the potentially lethal risk of opioid OD. Methods: This is a retrospective multi-institutional cohort study of patients undergoing 1 of 6 major elective inpatient operation from 2002 to 2011 using the Nationwide Inpatient Sample, an approximately 20% representative sample of all United States hospital admissions. Patients with postoperative OD were identified using ICD-9 codes for poisoning from opioids or adverse effects from opioids. Multivariate logistic regression was used to identify independent predictors. Results: Among 11,317,958 patients, 9458 (0.1%) had a postoperative OD; this frequency doubled over the study period from 0.6 to 1.1 overdoses per 1000 cases. Patients with postoperative OD died more frequently during their hospitalization (1.7% vs 0.4%, P < 0.001). Substance abuse history was the strongest predictor of OD (odds ratio = 14.8; 95% confidence interval: 12.7–17.2). Gender, age, income, geographic location, operation type, and certain comorbid diseases also predicted OD (P < 0.05). Hospital variables, including teaching status, size, and urban/rural location, did not predict postoperative OD. Conclusions: Postoperative OD is a rare, but potentially lethal complication, with increasing incidence. Postoperative monitoring and treatment safety interventions should be thoughtfully employed to target high-risk patients and avoid this potentially fatal complication.

OBJECTIVE The Massachusetts General Hospital (MGH) Department of Surgery established the Global Surgery Initiative (GSI) in 2013 to transform volunteer and mission-based global surgery efforts into an educational experience in surgical systems strengthening. The objective of this newly conceived mission is not only to perform advanced surgery but also to train surgeons beyond MGH through international partnerships across disciplines. At its inception, a clear pathway to achieve this was not established, and we sought to identify steps that were critical to realizing our mission statement. SETTING Massachusetts General Hospital, Boston, MA, USA and Mbarara Regional Referral Hospital, Mbarara, Uganda PARTICIPANTS Members of the MGH and MRRH Departments of Surgery including faculty, fellows, and residents RESULTS The MGH GSI steering committee identified 4 steps for sustaining a robust global surgery program: (1) administer a survey to the MGH departmental faculty, fellows, and residents to gauge levels of experience and interest, (2) catalog all ongoing global surgical efforts and projects involving MGH surgical faculty, fellows, and residents to identify areas of overlap and opportunities for collaboration, (3) establish a longitudinal partnership with an academic surgical department in a limited-resource setting (Mbarara University of Science and Technology (MUST) at Mbarara Regional Referral Hospital (MRRH)), and (4) design a formal curriculum in global surgery to provide interested surgical residents with structured opportunities for research, education, and clinical work. CONCLUSIONS By organizing the collective experiences of colleagues, synchronizing efforts of new and former efforts, and leveraging the funding resources available at the local institution, the MGH GSI hopes to provide academic benefit to our foreign partners as well as our trainees through longitudinal collaboration. Providing additional financial and organizational support might encourage more surgeons to become involved in global surgery efforts. Creating a partnership with a hospital in a limited-resource setting and establishing a formal global surgery curriculum for our residents allows for education and longitudinal collaboration. We believe this is a replicable model for building other academic global surgery endeavors that aim to strengthen health and surgical systems beyond their own institutions.

Background: The Lancet Commission on Global Surgery recommends that every country report its surgical volume and postoperative mortality rate. Little is known, however, about the numbers of operations performed and the associated postoperative mortality rate in low‐income countries or how to best collect these data. Methods: For one month, every patient who underwent an operation at a referral hospital in western Uganda was observed. These patients and their outcomes were followed until discharge. Prospective data were compared with data obtained from logbooks and patient charts to determine the validity of using retrospective methods for collecting these metrics. Results: Surgical volume at this regional hospital in Uganda is 8,515 operations/y, compared to 4,000 operations/y reported in the only other published data. The postoperative mortality rate at this hospital is 2.4%, similar to other hospitals in low‐income countries. Finding patient files in the medical records department was time consuming and yielded only 62% of the files. Furthermore, a comparison of missing versus found charts revealed that the missing charts were significantly different from the found charts. Logbooks, on the other hand, captured 99% of the operations and 94% of the deaths. Conclusion: Our results describe a simple, reproducible, accurate, and inexpensive method for collection of the Lancet Commission on Global Surgery variables using logbooks that already exist in most hospitals in low‐income countries. While some have suggested using risk‐adjusted postoperative mortality rate as a more equitable variable, our data suggest that only a limited amount of risk adjustment is possible given the limited available data.

Background and objectives It is Ugandan governmental policy that all surgical care delivered at government hospitals in Uganda is to be provided to patients free of charge. In practice, however, frequent stock-outs and broken equipment require patients to pay for large portions of their care out of their own pocket. The purpose of this study was to determine the financial impact on patients who undergo surgery at a government hospital in Uganda. Methods Every surgical patient discharged from a surgical ward at a large regional referral hospital in rural southwestern Uganda over a 3-week period in April 2016 was asked to participate. Patients who agreed were surveyed to determine their baseline level of poverty and to assess the financial impact of the hospitalization. Rates of impoverishment and catastrophic expenditure were then calculated. An “impoverishing expense” is defined as one that pushes a household below published poverty thresholds. A “catastrophic expense” was incurred if the patient spent more than 10% of their average annual expenditures. Results We interviewed 295 out of a possible 320 patients during the study period. 46% (CI 40–52%) of our patients met the World Bank’s definition of extreme poverty (

3.10/person/day). 31% of patients faced a catastrophic expenditure of more than 10% of their estimated total yearly expenses. 53% of the households in our study had to borrow money to pay for care, 21% had to sell possessions, and 17% lost a job as a result of the patient’s hospitalization. Only 5% of our patients received some form of charity. Conclusions and relevance Despite the government’s policy to provide “free care,” undergoing an operation at a government hospital in Uganda can result in a severe economic burden to patients and their families. Alternative financing schemes to provide financial protection are critically needed.

AbstractBackground Despite the existence of multiple validated risk assessment and quality benchmarking tools in surgery, their utility outside of high-income countries is limited. We sought to derive, validate and apply a scoring system that is both (1) feasible, and (2) reliably predicts mortality in a middle-income country (MIC) context.Methods A 5-step methodology was used: (1) development of a de novo surgical outcomes database modeled around the American College of Surgeons’ National Surgical Quality Improvement Program (ACS-NSQIP) in South Africa (SA dataset), (2) use of the resultant data to identify all predictors of in-hospital death with more than 90% capture indicating feasibility of collection, (3) use these predictors to derive and validate an integer-based score that reliably predicts in-hospital death in the 2012 ACS-NSQIP, (4) apply the score in the original SA dataset and demonstrate its performance, (5) identify threshold cutoffs of the score to prompt action and drive quality improvement.Results Following step one-three above, the 13 point Codman’s score was derived and validated on 211,737 and 109,079 patients, respectively, and includes: age 65 (1), partially or completely dependent functional status (1), preoperative transfusions ≥4 units (1), emergency operation (2), sepsis or septic shock (2) American Society of Anesthesia score ≥3 (3) and operative procedure (1–3). Application of the score to 373 patients in the SA dataset showed good discrimination and calibration to predict an in-hospital death. A Codman Score of 8 is an optimal cutoff point for defining expected and unexpected deaths.ConclusionWe have designed a novel risk prediction score specific for a MIC context. The Codman Score can prove useful for both (1) preoperative decision-making and (2) benchmarking the quality of surgical care in MIC’s.

Background Five billion people lack access to safe, affordable, and timely surgical and anesthesia care. Significant challenges remain in the provision of surgical care in low-resource settings. Uganda is no exception. Methods From September to November 2016, we conducted a mixed-methods countrywide surgical capacity assessment at 17 randomly selected public hospitals in Uganda. Researchers conducted 35 semi-structured interviews with key stakeholders to understand factors related to the provision of surgical care. The framework approach was used for thematic and explanatory data analysis. Results The Ugandan public health care sector continues to face significant challenges in the provision of safe, timely, and affordable surgical care. These challenges can be broadly grouped into preparedness and policy, service delivery, and the financial burden of surgical care. Hospital staff reported challenges including: (1) significant delays in accessing surgical care, compounded by a malfunctioning referral system; (2) critical workforce shortages; (3) operative capacity that is limited by inadequate infrastructure and overwhelmed by emergency and obstetric volume; (4) supply chain difficulties pertaining to provision of essential medications, equipment, supplies, and blood; (5) significant, variable, and sometimes catastrophic expenditures for surgical patients and their families; and (6) a lack of surgery-specific policies and priorities. Despite these challenges, innovative strategies are being used in the public to provide surgical care to those most in need. Conclusion Barriers to the provision of surgical care are cross-cutting and involve constraints in infrastructure, service delivery, workforce, and financing. Understanding current strengths and shortfalls of Uganda’s surgical system is a critical first step in developing effective, targeted policy and programming that will build and strengthen its surgical capacity.

Data Improvement Through Simplification: Implications for Low-Resource Settings

Geoffrey A. Anderson; Jordan D. Bohnen; Richard Trafford Spence; Lenka Ilcisin; Karim S. Ladha; David Chang

BACKGROUND/PURPOSE Anorectal malformation (ARM) is a common condition. Owing to scarcity of pediatric surgery services in Uganda, however, relatively little is known about this condition. METHODS This was a retrospective review of medical records of all patients admitted to Mbarara Regional Referral Hospital (MRRH) from January 2014 to May 2016. MRRH serves 3-8 million people in southwest Uganda. We also enrolled patients prospectively from June 2016 to December 2016. RESULTS 78 patients were enrolled in the study. 63.38% had delayed diagnosis (presenting >48 h after birth), and most of these were self-referrals from home. The most common malformation was a vestibular fistula. Associated congenital anomalies were seen in 20% of patients, and this was associated with increased mortality. These anomalies included limb, eye, ear and genitourinary anomalies as well as ventricular septal defects, patent ductus arteriosus, spina bifida and tracheoesophageal fistula. Posterior sagittal anorectoplasty (PSARP) was the definitive surgery used. It was performed in 58.97% of the patients. Median age of patients who underwent PSARP was 11 months. 73.91% of PSARP patients had their colostomies closed and 62.5% of these who were ≥3 years old had good continence outcomes. Overall mortality rate was 8.97%. CONCLUSION The majority of patients are diagnosed late. Vestibular fistula is the overall most common type of ARM. In males, however, rectourethral fistula is the most common type. Definitive surgery at MRRH is performed late. Continence outcomes are good and comparable to other countries with more resources.
