The International Standards for a Safe Practice of Anesthesia were developed on behalf of the World Federation of Societies of Anaesthesiologists (WFSA), a non-profit organization representing anesthesiologists in 150 countries, and the World Health Organization (WHO). The recommendations have been approved by WHO and the membership of WFSA. These Standards are applicable to all anesthesia providers throughout the world. They are intended to provide guidance and assistance to anesthesia providers, their professional organizations, hospital and facility administrators, and governments for maintaining and improving the quality and safety of anesthesia care. The Standards cover professional aspects; facilities and equipment; medications and intravenous fluids; monitoring; and the conduct of anesthesia. HIGHLY RECOMMENDED standards, the functional equivalent of mandatory standards, include (amongst other things): the continuous presence of a trained and vigilant anesthesia provider; continuous monitoring of tissue oxygenation and perfusion by clinical observation and a pulse oximeter; intermittent monitoring of blood pressure; confirmation of correct placement of an endotracheal tube (if used) by auscultation and carbon dioxide detection; the use of the WHO Safe Surgery Checklist; and a system for transfer of care at the end of an anesthetic. The International Standards represent minimum standards and the goal should always be to practice to the highest possible standards, preferably exceeding the standards outlined in this document.

Pediatric surgeons, anesthesia providers, and nurses from North America and other high-income countries are increasingly engaged in resource-limited areas, with short-term missions as the most common form of involvement. However, consensus recommendations currently do not exist for short-term missions in pediatric general surgery and associated perioperative care. The American Academy of Pediatrics (AAP) Delivery of Surgical Care Subcommittee and American Pediatric Surgical Association (APSA) Global Pediatric Surgery Committee, with the American Pediatric Surgical Nurses Association, Inc. (APSNA) Global Health Special Interest Group, and the Society for Pediatric Anesthesia (SPA) Committee on International Education and Service generated consensus recommendations for short-term missions based on extensive experience with short-term missions. Three distinct, but related areas were identified: (i) Broad goals of surgical partnerships between high-income countries and low- and middle-income countries. A previous set of guidelines published by the Global Paediatric Surgery Network Collaborative (GPSN) was endorsed by all groups; (ii) Guidelines for the conduct of short-term missions were developed, including planning, in-country perioperative patient care, post-trip follow-up, and sustainability; and (iii) travel and safety considerations critical to short-term mission success were enumerated. A diverse group of stakeholders developed these guidelines for short-term missions in low- and middle-income countries. These guidelines may be a useful tool to ensure safe, responsible, and ethical short-term missions given increasing engagement of high-income country providers in this work.

Introduction

Multiple pediatric surgical conditions require ostomies in low-middle-income countries. Delayed presentations increase the numbers of ostomies. Patients may live with an ostomy for a prolonged time due to the high backlog of cases with insufficient surgical capacity. In caring for these patients in Uganda, we frequently witnessed substantial socioeconomic impact of their surgical conditions.

Methods

The operative log at the only pediatric surgery referral center in Uganda was reviewed to assess the numbers of children receiving ostomies over a 3-year period. Charts for patients with anorectal malformations (ARM) and Hirschsprung’s disease (HD) were reviewed to assess delays in accessing care. Focus group discussions (FGD) were held with family members of children with ostomies based on themes from discussions with the surgical and nursing teams. A pilot survey was developed based on these themes and administered to a sample of patients in the outpatient clinic.

Results

During the period of January 2012-December 2014, there was one specialty-certified pediatric surgeon in the country. There were 493 ostomies placed for ARM (n = 234), HD (N = 114), gangrenous ileocolic intussusception (n = 95) and typhoid-induced intestinal perforation (n = 50). Primary themes covered in the FGD were: stoma care, impact on caregiver income, community integration of the child, impact on family unit, and resources to assist families. Many patients with HD and ARM did not present for colostomy until after 1 year of life. None had access to formal ostomy bags. 15 caregivers completed the survey. 13 (86%) were mothers and 2 (13%) were fathers. Almost half of the caregivers (n = 7, 47%) stated that their spouse had left the family. 14 (93%) caregivers had to leave jobs to care for the stoma. 14 respondents (93%) reported that receiving advice from other caregivers was beneficial.

Conclusion

The burden of pediatric surgical disease in sub-Saharan Africa is substantial with significant disparities compared to high-income countries. Significant socioeconomic complexity surrounds these conditions. While some solutions are being implemented, we are seeking resources to implement others. This data will inform the design of a more expansive survey of this patient population to better measure the socioeconomic impact of pediatric ostomies and guide more comprehensive advocacy and program development.

Introduction

Pediatric surgeons, anesthesia providers, and nurses from North America and other high-income countries (HICs) are increasingly engaged in resource-limited areas, with short-term missions (STMs) as the most common form of involvement. However, consensus recommendations currently do not exist for STMs in pediatric general surgery and associated perioperative care.

Methods

The American Academy of Pediatrics (AAP) Delivery of Surgical Care Subcommittee and American Pediatric Surgical Association (APSA) Global Pediatric Surgery Committee, with the American Pediatric Surgical Nurses Association, Inc. (APSNA) Global Health Special Interest Group, and the Society for Pediatric Anesthesia (SPA) Committee on International Education and Service generated consensus recommendations for STMs based on extensive experience with STMs.

Results

Three distinct, but related areas were identified: 1) Broad goals of surgical partnerships between HICs- and low and middle-income countries (LMICs). A previous set of guidelines published by the Global Paediatric Surgery Network Collaborative (GPSN), was endorsed by all groups; 2) Guidelines for the conduct of STMs were developed, including planning, in-country perioperative patient care, post-trip follow-up, and sustainability; 3) travel and safety considerations critical to STM success were enumerated.

Conclusion

A diverse group of stakeholders developed these guidelines for STMs in LMICs. These guidelines may be a useful tool to ensure safe, responsible, and ethical STMs given increasing engagement of HIC providers in this work.

Background

 The Lancet Commission on Global Surgery reported that 5 billion people lack access to safe, affordable surgical care. The majority of these people live in low-resource settings, where up to 50% of the population is children. (Debas HTP, Donkor A, Gawande DT, Jamison ME, Kruk, and Mock CN, editors. Essential Surgery. Disease Control Priorities. Third Edition, vol 1. Essential Surgery. Washington, DC: World Bank; 2015) on surgery included guidelines for the improvement of access to surgical care; however, these lack detail for children’s surgery.

Aim

 To produce guidance for low- and middle-income countries (LMICs) on the resources required for children’s surgery at each level of hospital care.

Methods

 The Global Initiative for Children’s Surgery (GICS) held an inaugural meeting at the Royal College of Surgeons in London in May 2016, with 52 surgical providers from 21 countries, including 27 providers from 18 LMICs. Delegates engaged in working groups over 2 days to prioritize needs and solutions for optimizing children’s surgical care; these were categorized into infrastructure, service delivery, training, and research. At a second GICS meeting in Washington in October 2016, 94 surgical care providers, half from LMICs, defined the optimal resources required at primary, secondary, tertiary, and national referral level through a series of working group engagements.

Results

 Consensus solutions for optimizing children’s surgical care included the following: · Establishing standards and integrating them into national surgical plans.. · Each country should have at least one children’s hospital.. · Designate, facilitate, and support regional training hubs covering all. · children’s surgical specialties.. · Establish regional research support centers.. An “Optimal Resources” document was produced detailing the facilities and resources required at each level of care.

Conclusion

 The Optimal Resources document has been produced by surgical providers from LMICs who have the greatest insight into the needs and priorities in their population. The document will be refined further through online GICS Working Groups and the World Health Organization for broad application to ensure all children have timely access to safe surgical care.

Background

Multiple institutions have developed international electives and sustainable global surgery initiatives to facilitate clinical, research, and outreach opportunities with hospitals in resource-poor areas. Despite increasing interest among programs, many institutions have not successfully reached potential involvement.

Objective

This study evaluates the experiences of Yale residents and faculty, measures interest in the development of an international surgical elective, and enumerates barriers to developing or participating in these opportunities. This was performed to develop a formalized elective and assess interest and capacity for surgical global health initiatives, as a seemingly increasing number of trainee applicants and residents were expressing interest in working in resource-poor settings.

Methods

Electronic survey of Yale Surgery residents and faculty analyzed using SPSS and Graphpad Prism.

Results

Among residents, previous global experience correlates with current interest in international opportunities, with 100% remaining interested, and 78% of those without prior experience also expressing interest (p = 0.018). Barriers to pursuing these activities included the use of vacation time, funding, scheduling, family obligations, and concern for personal safety. Among faculty, 28% of respondents have been involved internationally, and most (86%) expressed interest in additional opportunities and all were willing to take residents. Barriers to faculty participation included funding, relative value unit target reduction, protected time, and the desire for institutional support for such activities.

Conclusions

A substantial proportion of residents and faculty have experience in global health and motivation to pursue additional opportunities. The main barriers to participation are not a lack of interest, but rather needs for funding support, protected time, and institutional recognition of academic contributions. These findings are being used to develop a global surgery elective and establish long-term partnerships with international colleagues.

Background/aim

Intestinal atresia is one of the leading causes of neonatal intestinal obstruction (NIO). The purpose of this study was to analyze the presentation and outcome of IA and compare with those from both similar and high-income country settings.

Patients and methods

A retrospective review of prospectively collected data from patient charts and pediatric surgical database for 2012-2015 was performed. Epidemiological data and patient characteristics were analyzed and outcomes were compared with those reported in other LMICs and high-income countries (HICs). Unmet need was calculated along with economic valuation or economic burden of surgical disease.

Results

Of 98 patients, 42.9% were male. 35 patients had duodenal atresia (DA), 60 had jejunio-ileal atresia (JIA), and 3 had colonic atresia. The mean age at presentation was 7.14 days for DA and 6.7 days for JIA. Average weight for DA and JIA was 2.2 and 2.12 kg, respectively. All patients with DA and colonic atresia underwent surgery, and 88.3% of patients with JIA had surgery. Overall mortality was 43% with the majority of deaths attributable to aspiration, anastomotic leak, and sepsis. 3304 DALYs were calculated as met compared to 25,577 DALYs’ unmet.

Conclusion

Patients with IA in Uganda present late in the clinical course with high morbidity and mortality attributable to a combination of late presentation, poor nutrition status, surgical complications, and likely underreporting of associated anomalies rather than surgical morbidity alone.

  • Trauma

Background

Blood transfusion, a practice under re-evaluation in general, remains common among thermal burn patients due to the hematological alterations associated with burns that manifest as anemia. Today advocacy is for restrictive blood transfusion taking into account individual patient characteristics. We went out to identify the parameters that may determine transfusion requirement and the time to blood transfusion for thermal burn patients in Mulago Hospital in order to build statistics and a basis to standardize future practice and Hospital protocol.

Methods

112 patients with thermal burns were enrolled into a prospective cohort study conducted in the Surgical Unit of the Accidents and Emergency Department and Burns Unit of Mulago Hospital. Relevant data on pre-injury, injury and post-injury factors was collected including relevant laboratory investigations and treatment modalities like surgical intervention. Patients were clinically followed up for a maximum period of 28 days and we identified those that were transfused.

Results

22.3% of patients were transfused. The median time to transfusion was 17 days from time of injury and varied with different patient characteristics. The median pre-transfusion hemoglobin (Hb) level was 8.2 g/dL. Transfusion was significantly related to; admission to the intensive care unit (p = 0.001), a body mass index (BMI) <2 kg/m (p = 0.021), % total burn surface area (TBSA) >20 (p = 0.049), pre-existing illness (p = 0.046), and white blood cell (WBC) count <4000 or >12,000/μL (p = 0.05).

Conclusion

Pre-existing illnesses, a low BMI, TBSA of >20%, admission to the intensive care unit and abnormalities in the WBC count are useful predictors of blood transfusion among thermal burns patients admitted to Mulago Hospital. The precise time to transfusion from time of burns injury cannot be generalized. With close monitoring of each individual patient lies the appropriateness and timeliness of their management.

Background

African pediatric surgery (PS) faces multiple challenges. Information regarding existing resources is limited. We surveyed African pediatric surgeons to determine available resources and clinical, educational, and collaborative needs.

Methods

Members of the Pan-African Pediatric Surgical Association (PAPSA) and the Global Pediatric Surgery Network (GPSN) completed a structured email survey covering PS providers, facilities, resources, workload, education/training, disease patterns, and collaboration priorities.

Results

Of 288 deployed surveys, 96 were completed (33%) from 26 countries (45% of African countries). Median PS providers/million included 1 general surgeon and 0.26 pediatric surgeons. Median pediatric facilities/million included 0.03 hospitals, 0.06 ICUs, and 0.17 surgical wards. Neonatal ventilation was available in 90% of countries, fluoroscopy in 70%, TPN in 50%, and frozen section pathology in 35%. Median surgical procedures/institution/year was 852. Median waiting time was 40days for elective procedures and 7 days? for emergencies. Weighted average percent mortality for key surgical conditions varied between 1% (Sierra Leone) and 54% (Burkina Faso). Providers ranked collaborative professional development highest and direct clinical care lowest priority in projects with high-income partners.

Conclusions

The broad deficits identified in PS human and material resources in Africa suggest the need for a global collaborative effort to address the PS gaps.

Purpose

This article describes the functioning of the international drug control system, its integration into national legislation and policy, and the collective impact on access to medicines.

Source

We conducted a review of the three international drug control conventions, peer-reviewed articles, and grey literature known to the authors that describes national and international drug control systems and their impact on access to controlled medicines. This review was supplemented with literature derived from a structured search of MEDLINE for articles relating to medical uses of ketamine in low- and middle-income countries conducted to strengthen an advocacy campaign. We illustrate the impact of the drug control system on access to medicines through an analysis of current levels of availability of opioids in many countries as well as through a description of the ongoing advocacy work to ensure the availability of ketamine for medical care in low-income countries.

Principal findings

The complexity of the international drug control system, along with health providers’ lack of knowledge regarding key provisions, presents a barrier to improving access to safe anesthesia care in low- and middle-income countries. Fifteen of the 46 essential medicines of potential relevance to perioperative care are listed under one or more of the schedules of the three international drug control conventions and, subsequently, are required to be under national controls, potentially decreasing their availability for medical use.

Conclusion

Improving the capacity and quality of anesthesia care in low- and middle-income countries requires attention to improving access to controlled medicines. Anesthesiologists and others involved in global health work should collaborate with policymakers and others to improve national and international drug control legislation to ensure that attempts to thwart illicit drug trafficking and use do not compromise availability of controlled medicines.

Background

Sub-Saharan Africa has a great burden of critical illness with limited health care resources. We evaluated the feasibility and utility of the modified Sequential Organ Function Assessment (mSOFA) score in assessing morbidity and mortality in the National Referral Hospital’s intensive care unit (ICU) for one year.

Methods

We conducted a prospective, observational cohort study on patients above 12 years of age admitted to the ICU at Mulago Hospital (Kampala, Uganda). All SOFA scores were determined at admission and at 48 h. We modified the SOFA score by replacing the PaO/FiO ratio with SPO/FiO. The primary outcome was ICU mortality.

Results

This ICU cohort of 118 patients had a mean age of 37 years and an ICU mortality rate of 46.6%. Non-survivors had higher initial (7.7 SD 3.8 vs. 5.5 SD 3.3; p = 0.007), mean (8.1 SD 3.9 vs 4.7 SD 2.6; p < 0.001) and highest mSOFA scores (9.4 SD 4.2 vs. 5.8 SD 3.2; p < 0.001), with an increase of 1.0 (SD 3.1) mSOFA on average after 48 h when compared to survivors (p < 0.001). The area under the receiver operating characteristic curves for each mSOFA category was: initial-0.68, mean-0.76, highest-0.76 and delta mSOFA-0.74. Multivariate logistic regression analysis showed no significant association between mSOFA scores and mortality.

Conclusion

Our results confirm that calculation of the mSOFA score is feasible for an ICU population in a resource-limited country. More data are needed to test for an association between mSOFA and mortality.

Purpose

Neonatal mortality from gastroschisis in sub-Saharan Africa is high, while in high-income countries, mortality is less than 5%. The purpose of this study was to describe the maternal and neonatal characteristics of gastroschisis in Uganda, estimate the mortality and elucidate opportunities for intervention.

Methods

An ethics-approved, prospective cohort study was conducted over a one-year period. All babies presenting with gastroschisis in Mulago Hospital in Kampala, Uganda were enrolled and followed up to 30days. Univariate and descriptive statistical analyses were performed on demographic, maternal, perinatal, and clinical outcome data.

Results

42 babies with gastroschisis presented during the study period. Mortality was 98% (n=41). Maternal characteristics demonstrate a mean maternal age of 21.8 (±3.9) years, 40% (n=15) were primiparous, and fewer than 10% (n=4) of mothers reported a history of alcohol use, and all denied cigarette smoking and NSAID use. Despite 93% (n=39) of mothers receiving prenatal care and 24% (n=10) a prenatal ultrasound, correct prenatal diagnosis was 2% (n=1). Perinatal data show that 81% of deliveries occurred in a health facility. The majority of babies (58%) arrived at Mulago Hospital within 12h of birth, however 52% were breastfeeding, 53% did not have intravenous access and only 19% had adequate bowel protection in place. Four patients (9%) arrived with gangrenous bowel. One patient, the only survivor, had primary closure. Average time to death was 4.8days [range<1 to 14days].

Conclusion

The mortality of gastroschisis in Uganda is alarmingly high. Improving prenatal diagnosis and postnatal care of babies in a tertiary center may improve outcome.

Background

Understanding the economic value of health interventions is essential for policy makers to make informed resource allocation decisions. The objective of this systematic review was to summarize available information on the economic impact of children’s surgical care in low- and middle-income countries (LMICs).

Methods

We searched MEDLINE (Pubmed), Embase, and Web of Science for relevant articles published between Jan. 1996 and Jan. 2015. We summarized reported cost information for individual interventions by country, including all costs, disability weights, health outcome measurements (most commonly disability-adjusted life years [DALYs] averted) and cost-effectiveness ratios (CERs). We calculated median CER as well as societal economic benefits (using a human capital approach) by procedure group across all studies. The methodological quality of each article was assessed using the Drummond checklist and the overall quality of evidence was summarized using a scale adapted from the Agency for Healthcare Research and Quality.

Findings

We identified 86 articles that met inclusion criteria, spanning 36 groups of surgical interventions. The procedure group with the lowest median CER was inguinal hernia repair ($15/DALY). The procedure group with the highest median societal economic benefit was neurosurgical procedures ($58,977). We found a wide range of study quality, with only 35% of studies having a Drummond score ≥ 7.

Interpretation

Our findings show that many areas of children’s surgical care are extremely cost-effective in LMICs, provide substantial societal benefits, and are an appropriate target for enhanced investment. Several areas, including inguinal hernia repair, trichiasis surgery, cleft lip and palate repair, circumcision, congenital heart surgery and orthopedic procedures, should be considered “Essential Pediatric Surgical Procedures” as they offer considerable economic value. However, there are major gaps in existing research quality and methodology which limit our current understanding of the economic value of surgical care.

Background

Universal access to pulse oximetry worldwide is often limited by cost and has substantial public health consequences. Low-cost pulse oximeters have become increasingly available with limited regulatory agency oversight. The accuracy of these devices often has not been validated, raising questions about performance.

Methods

The accuracy of 6 low-cost finger pulse oximeters during stable arterial oxygen saturations (SaO2) between 70% and 100% was evaluated in 22 healthy subjects. Oximeters tested were the Contec CMS50DL, Beijing Choice C20, Beijing Choice MD300C23, Starhealth SH-A3, Jumper FPD-500A, and Atlantean SB100 II. Inspired oxygen, nitrogen, and carbon dioxide partial pressures were monitored and adjusted via a partial rebreathing circuit to achieve 10 to 12 stable target SaO2 plateaus between 70% and 100% and PaCO2 values of 35 to 45 mm Hg. Comparisons of pulse oximeter readings (SpO2) with arterial SaO2 (by Radiometer ABL90 and OSM3) were used to calculate bias (SpO2 – SaO2) mean, precision (SD of the bias), and root mean square error (ARMS).

Results

Pulse oximeter readings corresponding to 536 blood samples were analyzed. Four of the 6 oximeters tested showed large errors (up to -6.30% mean bias, precision 4.30%, 7.53 ARMS) in estimating saturation when SaO2 was reduced <80%, and half of the oximeters demonstrated large errors when estimating saturations between 80% and 90%. Two of the pulse oximeters tested (Contec CMS50DL and Beijing Choice C20) demonstrated ARMS of <3% at SaO2 between 70% and 100%, thereby meeting International Organization for Standardization (ISO) criteria for accuracy.

Conclusions

Many low-cost pulse oximeters sold to consumers demonstrate highly inaccurate readings. Unexpectedly, the accuracy of some low-cost pulse oximeters tested here performed similarly to more expensive, ISO-cleared units when measuring hypoxia in healthy subjects. None of those tested here met World Federation of Societies of Anaesthesiologists standards, and the ideal testing conditions do not necessarily translate these findings to the clinical setting. Nonetheless, further development of accurate, low-cost oximeters for use in clinical practice is feasible and, if pursued, could improve access to safe care, especially in low-income countries.

Background

Surgical care delivery is poorly understood in resource-limited settings. To effectively move toward universal health coverage, there is a critical need to understand surgical care delivery in developing countries. This study aims to identify the barriers and facilitators of surgical care delivery at Soroti Regional Referral Hospital in Uganda.

Methods

In this mixed methods study, we (1) applied the Surgeons OverSeas’ Personnel, Infrastructure, Procedures, Equipment, and Supplies tool to assess surgical capacity; (2) retrospectively reviewed inpatient records; (3) conducted four semistructured focus group discussions with 18 purposively sampled providers involved in perioperative care; and (4) observed the perioperative process of care using a time and motion approach. Descriptive statistics were generated from quantitative data. Qualitative data were thematically analyzed.

Results

The Personnel, Infrastructure, Procedures, Equipment, and Supplies survey revealed severe deficiencies in workforce (P-score = 14) and infrastructure (I-score = 5). Equipment, supplies, and procedures were generally available. Male and female wards were overbooked 83% and 60% of the time, respectively. Providers identified lack of space, patient overload, and superfluous patients’ attendants as barriers to surgical care. Workforce challenges were tackled using teamwork and task sharing. Inadequate equipment and processes were addressed using improvisations. All observed subjects (n = 31) received interventions. The median decision-to-intervention time was 2.5 h (Interquartile Range [IQR], 0.4, 21.4). However, 48% of subjects experienced delays. Median decision-to-intervention delay was 14.8 h (IQR, 0.9, 26.6).

Conclusions

Despite severe workforce and physical infrastructural deficiencies at Soroti Regional Referral Hospital, providers are adjusting and innovating to deliver surgical care.

Introduction

Colorectal polyps usually present with rectal bleeding and are associated with increased risk of colorectal carcinoma. Evaluation and management in resource-poor areas present unique challenges.

Presentation of case

This 15 year-old boy presented with 9 years of painless rectal bleeding and 2 years of a prolapsing rectal mass after passing stool. He had 3 nephews with similar symptoms. On clinical assessment and initial exam under anesthesia, an impression of a polyposis syndrome was made and a biopsy taken from the mass that revealed inflammatory polyps with no dysplasia. He was identified during a pediatric surgical outreach to a rural area with no endoscopy, limited surgical services, and no genetic testing available, even at a tertiary center. He subsequently had a three-stage proctocolectomy and ileal pouch anal anastomosis with good outcome after referral to a tertiary care center. The surgical specimen showed many polyps scattered through the colon.

Discussion

In the absence of endoscopic surveillance and diagnostic services including advanced pathology and genetic testing, colorectal polyposis syndromes are a significant challenge if encountered in these settings. Reports from similar settings have not included this surgical treatment, often opting for partial colectomy. Nonetheless, good outcomes can be achieved even given these constraints. The case also illustrates the complexity of untreated chronic pediatric surgical disease in rural resource-poor areas with limited health care access.

Conclusion

Polyposis syndromes in children present unique challenges in rural resource-poor settings. Good outcomes can be achieved with total proctocolectomy and ileal pouch anastomosis.

Recent initiatives in global health have emphasized universal coverage of essential health services. Surgical conditions play a critical role in child health in resource-poor areas. This article discusses (1) the spectrum of pediatric surgical conditions and their treatment; (2) relevance to recent advances in global surgery; (3) challenges to the prioritization of surgical care within child health, and possible solutions; (4) a case example from a resource-poor area (Uganda) illustrating some of these concepts; and (5) important child health initiatives with which surgical services should be integrated. Pediatric surgery providers must lead the effort to prioritize children’s surgery in health systems development.

The body of literature addressing surgical and anesthesia care for children in low- and middle-income countries (LMICs) is small. This lack of research hinders full understanding of the nature of many surgical conditions in LMICs and compromises potential efforts to alleviate the significant health, welfare and economic burdens surgical conditions impose on children, families and countries. This article will evaluate the need for improved global pediatric surgery research by (1) presenting the current state of surgical research for children in LMICs and (2) discussing methods and opportunities for improvement within the political context of current global health priorities.

The World Health Organization (WHO) Surgical Safety Checklist is a cost-effective tool that has been shown to improve patient safety. We explored the applicability and effectiveness of quality improvement methodology to implement the WHO checklist and surgical counts at Mbarara Regional Referral Hospital in Uganda between October 2012 and September 2013. Compliance rates were evaluated prospectively and monthly structured feedback sessions were held. Checklist and surgical count compliance rates increased from a baseline median (IQR [range]) of 29.5% (0-63.5 [0-67.0]) to 85.0% (82.8-87.5 [79.0-93.0]) and from 25.5% (0-52.5 [0-60.0]) to 83.0% (80.8-85.5 [69.0-89.0]), respectively. The mean all-or-none completion rate of the checklist was 69.3% (SD 7.7, 95% CI [64.8-73.9]). Use of the checklist was associated with performance of surgical counts (p value < 0.001; r(2) = 0.91). Pareto analysis showed that understaffing, malfunctioning and lack of equipment were the main challenges. A carefully designed quality improvement project, including stepwise incremental change and standardisation of practice, can be an effective way of improving clinical practice in low-income settings.
