Background

Anorectal malformations (ARMs) have an incidence of up to 1 in 4000 live births and can require immediate neonatal surgery due to associated intestinal blockage. Due to limited surgical access, Ugandan children present late and undergo three separate staged operations: (1) initial colostomy formation; (2) repair of the ARM (called anoplasty); and (3) colostomy closure. Three operations result in long treatment duration, potential complications with each procedure, delays in care, and stigmata associated with colostomies. By offering primary repair for ARMs in a resource-limited setting, we expect to: reduce healthcare expenditure by families, length of treatment, length of hospital stay, frequency of hospital visits, and social rejection.

Materials and methods

A pragmatic clinical trial was performed examining the effectiveness of primary repair (prospective arm) and comparing it with the three-stage repairs (retrospective arm).

Results

Of the 241 patients included for analysis-157 patients had a three-stage repair, whereas 84 patients had one- or two-stage repair. The median [IQR age at the last surgery (days) was 730.0 (365.0, 1460.0) vs 180.0 (90.0, 285.0)] in three-stage and one- or two-stage repairs, respectively. There was no difference in postoperative complications compared to patients who had three-stage repair. Patients who had a two-stage repair had less time with colostomy than those with three-stage repair. Non-inferiority analysis demonstrated that the primary repair approach was non-inferior to the three-stage approach.

Conclusions

Primary repair for ARM is effective in low-income settings. It allows for less time with colostomy with no difference in post-operative complications. The decision on approach for treatment depends on the surgeon’s experience and clinical judgment.

Background

One of the greatest challenges to conducting multicenter research studies in low and middle-income countries (LMICs) is the heterogeneity in regulatory processes across sites. Previous studies have reported variations in requirements with a lack of standardization in the Institutional Review Board (IRB) processes between centers, imposing barriers for approval, participation, and development of multicenter research.

Objectives

To describe the regulatory process, variability and challenges faced by pediatric researchers in LMICs during the IRB process of an international multicenter observational point prevalence study (Global PARITY).

Design

A 16-question multiple-choice online survey was sent to site principal investigators (PIs) at PARITY study participating centers to explore characteristics of the IRB process, costs, and barriers to research approval. A shorter survey was employed for sites that expressed interest in participating in Global PARITY and started the approval process, but ultimately did not participate in data collection (non-participating sites) to assess IRB characteristics.

Results

Of the 91 sites that sought IRB approval, 46 were successful in obtaining approval and finishing the data collection process. The survey was completed by 46 (100%) participating centers and 21 (47%) non-participating centers. There was a significant difference between participating and non-participating sites in IRB approval of a waiver consent and in the requirement for a legal review of the protocol. The greatest challenge to research identified by non-participating sites was a lack of research time and the lack of institutional support.

Conclusions

Global collaborative research is crucial to increase our understanding of pediatric critical care conditions in hospitals of all resource-levels and IRBs are required to ensure that this research complies with ethical standards. Critical barriers restrict research activities in some resource limiting countries. Increasing the efficiency and accessibility of local IRB review could greatly impact participation of resource limited sites and enrollment of vulnerable populations.

Introduction

Anorectal malformations (ARMs) may be associated with congenital anomalies affecting other body parts namely vertebral, anorectal, cardiac, tracheoesophageal, renal, and limb (VACTERL) with varying incidences of 7%-60% . Genitourinary defects might occur approximately in 50% of all patients with anorectal malformations hence patients should be evaluated from birth to rule out these defects.

Objective

To identify urological anomalies associated with anorectal malformation in southwestern Uganda.

Study design

This was a descriptive retrospective cohort study conducted at our regional referral hospital in Southwestern Uganda involving patients who have undergone surgical correction of ARMs between June 2021 and July 2023.

Results

The overall prevalence of renal anomalies in our study patient population was 18.05%. Of those with ARM-associated renal anomalies, Specific anomalies included; renal agenesis (6.8%), hydronephrosis, (4.5%), duplex collecting system (3.8%), crossed fused kidney (1.5%), and ectopic kidney (0.75%). (Table) DISCUSSION: We found that the prevalence of ARM-associated renal anomalies was 18.05%, and the commonest anomaly was unilateral agenesis (6.8%) similar to other studies. Previous data have shown renal anomalies are common anomalies in ARM. While the exact values vary across studies, they all concluded that the rate of associated anomalies is extremely high in ARMs and warrants a thorough preoperative investigation once the ARMs are detected. This finding therefore underscores the importance of thorough evaluation and a multidisciplinary approach of care and follow-up system for ARM management including urologists even when the children are asymptomatic now. The main limitation of our study was missing information on patients’ charts, we were not able to get the diagnosis since most patients didn’t have their discharge forms at the time of evaluation.

Conclusion

ARM associated with renal anomalies may remain undiagnosed and asymptomatic. Those identified as asymptomatic need to be followed in a multidisciplinary fashion including pediatric urologists.

Introduction

Traumatic injury is responsible for eight million childhood deaths annually. In Uganda, there is a paucity of comprehensive data describing the burden of pediatric trauma, which is essential for resource allocation and surgical workforce planning. This study aimed to ascertain the burden of non-adolescent pediatric trauma across four Ugandan hospitals.

Methods

We performed a descriptive review of four independent and prospective pediatric surgical databases in Uganda: Mulago National Referral Hospital (2012-2019), Mbarara Regional Referral Hospital (2015-2019), Soroti Regional Referral Hospital (SRRH) (2016-2019), and St Mary’s Hospital Lacor (SMHL) (2016-2019). We sub-selected all clinical encounters that involved trauma. The primary outcome was the distribution of injury mechanisms. Secondary outcomes included operative intervention and clinical outcomes.

Results

There was a total of 693 pediatric trauma patients, across four hospital sites: Mulago National Referral Hospital (n = 245), Mbarara Regional Referral Hospital (n = 29), SRRH (n = 292), and SMHL (n = 127). The majority of patients were male (63%), with a median age of 5 [interquartile range = 2, 8]. Chiefly, patients suffered blunt injury mechanisms, including falls (16.2%) and road traffic crashes (14.7%) resulting in abdominal trauma (29.4%) and contusions (11.8%). At SRRH and SMHL, from which orthopedic data were available, 27% of patients suffered long-bone fractures. Overall, 55% of patients underwent surgery and 95% recovered to discharge.

Conclusions

In Uganda, non-adolescent pediatric trauma patients most commonly suffer injuries due to falls and road traffic crashes, resulting in high rates of abdominal trauma. Amid surgical workforce deficits and resource-variability, these data support interventions aimed at training adult general surgeons to provide emergency pediatric surgical care and procedures.

Introduction

The incidence of pediatric Wilms’ tumor (WT) is high in Africa, though patients abandon treatment after initial diagnosis. We sought to identify factors associated with WT treatment abandonment in Uganda.

Methods

A cohort study of patients < 18 years with WT in a Ugandan national referral hospital examined clinical and treatment outcomes data, comparing children whose families adhered to and abandoned treatment. Abandonment was defined as the inability to complete neoadjuvant chemotherapy and surgery for patients with unilateral WT and definitive chemotherapy for patients with bilateral WT. Patient factors were assessed via bivariate logistic regression.

Results

137 WT patients were included from 2012 to 2017. The mean age was 3.9 years, 71% (n = 98) were stage III or higher. After diagnosis, 86% (n = 118) started neoadjuvant chemotherapy, 59% (n = 82) completed neoadjuvant therapy, and 55% (n = 75) adhered to treatment through surgery. Treatment abandonment was associated with poor chemotherapy response (odds ratio [OR] 4.70, 95% confidence interval [CI] 1.30-17.0) and tumor size > 25 cm (OR 2.67, 95% CI 1.05-6.81).

Conclusions

Children with WT in Uganda frequently abandon care during neoadjuvant therapy, particularly those with large tumors with poor response. Further investigation into the factors that influence treatment abandonment and a deeper understanding of tumor biology are needed to improve treatment adherence of children with WT in Uganda.

Purpose

Surgery provides vital services to diagnose, treat, and palliate patients suffering from malignancies. However, despite its importance, there is little information on the delivery of surgical oncology services in Tanzania.

Methods

Operative logbooks were reviewed at all national referral hospitals that offer surgery, all zonal referral hospitals in Mainland Tanganyika and Zanzibar, and a convenience sampling of regional referral hospitals in 2022. Cancer cases were identified by postoperative diagnosis and deidentified data were abstracted for each cancer surgery. The proportion of the procedures conducted for patients with cancer and the total number of cancer surgeries done within the public sector were calculated and compared with a previously published estimate of the surgical oncology need for the country.

Results

In total, 69,195 operations were reviewed at 10 hospitals, including two national referral hospitals, five zonal referral hospitals, and three regional referral hospitals. Of the cases reviewed, 4,248 (6.1%) were for the treatment of cancer. We estimate that 4,938 cancer surgeries occurred in the public sector in Tanzania accounting for operations conducted at hospitals not included in our study. Prostate, breast, head and neck, esophageal, and bladder cancers were the five most common diagnoses. Although 387 (83%) of all breast cancer procedures were done with curative intent, 506 (87%) of patients with prostate and 273 (81%) of patients with esophageal cancer underwent palliative surgery.

Conclusion

In this comprehensive assessment of surgical oncology service delivery in Tanzania, we identified 4,248 cancer surgeries and estimate that 4,938 likely occurred in 2022. This represents only 25% of the estimated 19,726 cancer surgeries that are annually needed in Tanzania. These results highlight the need to identify strategies for increasing surgical oncology capacity in the country.

Purpose

Intestinal obstruction caused by intestinal atresia is a surgical emergency in newborns. Outcomes for the jejunal ileal atresia (JIA), the most common subtype of atresia in low-income countries (LIC), are poor. We sought to assess the impact of utilizing the Bishop-Koop (BK) approach to JIA in improving outcomes.

Methods

A retrospective cohort study was performed on children with complex JIA (Type 2-4) treated at our national referral hospital from 1/2018 to 12/2022. BK was regularly used starting 1/1/2021, and outcomes between 1/2021 and 12/2022 were compared to those between 1/2018 and 12/2020. Statistical significance was set at p < 0.05.

Results

A total of 122 neonates presented with JIA in 1/2018-12/2022, 83 of whom were treated for complex JIA. A significant decrease (p = 0.03) was noted in patient mortality in 2021 and 2022 (n = 33, 45.5% mortality) compared to 2018-2020 (n = 35, 71.4% mortality). This translated to a risk reduction of 0.64 (95% CI 0.41-0.98) with the increased use of BK.

Conclusion

Increased use of BK anastomoses with early enteral nutrition and decreased use of primary anastomosis improves outcomes for neonates with severe JIA in LIC settings. Implementing this surgical approach in LICs may help address the disparities in outcomes for children with JIA.

Background

The Plastic Surgery Foundation’s Surgeons in Humanitarian Alliance for Reconstruction, Research and Education (SHARE) program seeks to expand surgical capacity worldwide through mentorship and training for local plastic surgeons. This study aims to define the need for microsurgery training among SHARE global fellows and describe results of a pilot course.

Methods

Ten participants of the SHARE Virtual Microsurgical Skills Course were asked to complete an anonymous survey. Pre- and post-course response rates were 100% and 50.0%, respectively.

Results

There was a high incidence of microsurgical problems encountered in the clinical setting. Resource availability was varied, with high access to loupes (100%), yet limited access to microsurgery instruments (50%), medications (40%), operating microscope (20%), skilled nursing (0%) and appropriate peri-operative care settings (0%). Participants identified vessel preparation, instrument selection, and suture handling as priority learning objectives for a microsurgery skills course. Post-course satisfaction with learning objectives was high (60% “very good,” 40% “excellent”). Participants reported high levels of improvement in suture handling (Likert 4.60±0.55), end-to-end anastomosis (4.40±0.55), instrument selection (4.20±0.45), vessel preparation (4.20±0.45), and economy of motion (4.20±0.45).

Conclusions

This study demonstrates a high frequency of reconstructive problems encountered by global fellows yet low access to appropriate resources to perform microsurgical procedures. Initial results from a pilot virtual microsurgery course demonstrate very high satisfaction and high self-rated improvement in key microsurgical skills. The virtual course is an effective and accessible format for training surgeons in basic microsurgery skills and can be augmented by providing longitudinal opportunities for remote feedback.

The true global burden of paediatric critical illness remains unknown. Studies on children with life-threatening conditions are hindered by the absence of a common definition for acute paediatric critical illness (DEFCRIT) that outlines components and attributes of critical illness and does not depend on local capacity to provide critical care. We present an evidence-informed consensus definition and framework for acute paediatric critical illness. DEFCRIT was developed following a scoping review of 29 studies and key concepts identified by an interdisciplinary, international core expert panel (n=24). A modified Delphi process was then done with a panel of multidisciplinary health-care global experts (n=109) until consensus was reached on eight essential attributes and 28 statements as the basis of DEFCRIT. Consensus was reached in two Delphi rounds with an expert retention rate of 89%. The final consensus definition for acute paediatric critical illness is: an infant, child, or adolescent with an illness, injury, or post-operative state that increases the risk for or results in acute physiological instability (abnormal physiological parameters or vital organ dysfunction or failure) or a clinical support requirement (such as frequent or continuous monitoring or time-sensitive interventions) to prevent further deterioration or death. The proposed definition and framework provide the conceptual clarity needed for a unified approach for global research across resource-variable settings. Future work will centre on validating DEFCRIT and determining high priority measures and guidelines for data collection and analysis that will promote its use in research.

Introduction

Small bowel obstruction (SBO) is one of the most common causes for hospital admission in Ethiopia. The use of water-soluble contrast agents (WSCAs) such as Gastrografin to manage adhesive SBO can predict nonoperative resolution of SBO and reduce decision time to surgery and length of hospital stay. However, nothing is known about practice patterns and Gastrografin use in low-income settings. We sought to characterize current management practices, including use of WSCAs, as well as outcomes for patients with SBO in Addis Ababa, Ethiopia.

Methods

We conducted a mixed-methods study consisting of a survey of surgeons throughout Ethiopia and a retrospective record review at five public, tertiary care-level teaching hospitals in Addis Ababa.

Results

Of the 76 surgeons who completed the survey, 63% had heard of the use of WSCAs for SBO and only 11% used oral agents for its management. Chart review of 149 patients admitted with SBO showed the most common etiology was adhesion (39.6% of admissions), followed by small bowel volvulus (20.8%). Most patients (83.2%) underwent surgery during their admission. The most common diagnosis in patients who did not require surgery was also adhesion (68.0%), as well as for those who had surgery (33.9%), followed by small bowel volvulus (24.2%).

Conclusions

The etiology of SBO in Ethiopia may be changing, with postoperative adhesions becoming more common than other historically more prevalent causes. Although a Gastrografin protocol as a diagnostic and potentially therapeutic aid for SBO is feasible in this population and setting, challenges can be anticipated, and future studies of protocol implementation and effectiveness are needed to further inform its utility in Ethiopia and other low-income and middle-income countries.

Lack of access to pediatric medical devices and innovative technology contributes to global disparities in children’s surgical care. There are currently many barriers that prevent access to these technologies in low- and middle-income countries (LMICs). Technologies that were designed for the needs of high-income countries (HICs) may not fit the resources available in LMICs. Likewise, obtaining these devices are costly and require supply chain infrastructure. Once these technologies have reached the LMIC, there are many issues with sustainability and maintenance of the devices. Ideally, devices would be created for the needs and resources of LMICs, but there are many obstacles to innovation that are imposed by institutions in both HICs and LMICs. Fortunately, there is a growing interest for development of this space, and there are many examples of current technologies that are paving the way for future innovations. Innovations in simulation-based training with incorporated learner self-assessment are needed to fast-track skills acquisition for both specialist trainees and non-specialist children’s surgery providers, to scale up access for the larger population of children. Pediatric laparoscopy and imaging are some of the innovations that could make a major impact in children’s surgery worldwide.

Importance

Surgical infections are a major cause of perioperative morbidity and mortality, particularly in low-resource settings. Clean Cut, a 6-month quality improvement program developed by the global nonprofit organization Lifebox, has demonstrated improvements in postoperative infectious complications. However, the pilot program required intense external programmatic and resource support.

Objective

To examine the improvement in adherence to infection prevention and control standards and rates of postoperative infections in hospitals in the Clean Cut program after implementation strategies were updated and program execution was refined.

Design, setting, and participants

This cohort study evaluated and refined the Clean Cut implementation strategy to enhance scalability based on a qualitative study of its pilot phase, including formalizing programmatic and educational materials, building an automated data entry and analysis platform, and reorganizing hospital-based team composition. Clean Cut was introduced from January 1, 2019, to February 28, 2022, in 7 Ethiopian hospitals that had not previously participated in the program. Prospective data initiated on arrival in the operating room were collected, and patients were followed up through hospital discharge and with 30-day follow-up telephone calls.

Exposure

Implementation of the refined Clean Cut program.

Main outcomes and measures

The primary outcome was surgical site infection (SSI); secondary outcomes were adherence to 6 infection prevention standards, mortality, hospital length of stay, and other infectious complications.

Results

A total of 3364 patients (mean [SD] age, 26.5 [38.0] years; 2196 [65.3%] female) from 7 Ethiopian hospitals were studied (1575 at baseline and 1789 after intervention). After controlling for confounders, the relative risk of SSIs was reduced by 34.0% after program implementation (relative risk, 0.66; 95% CI, 0.54-0.81; P < .001). Appropriate Surgical Safety Checklist use increased from 16.3% to 43.0% (P < .001), surgeon hand and patient skin antisepsis improved from 46.0% to 66.0% (P < .001), and timely antibiotic administration improved from 17.8% to 39.0% (P < .001). Surgical instrument (38.7% vs 10.2%), linen sterility (35.5% vs 12.8%), and gauze counting (89.2% vs 82.5%; P < .001 for all comparisons) also improved significantly.

Conclusions and relevance

A modified implementation strategy for the Clean Cut program focusing on reduced external resource and programmatic input from Lifebox, structured education and training materials, and wider hospital engagement resulted in outcomes that matched our pilot study, with improved adherence to recognized infection prevention standards resulting in a reduction in SSIs. The demonstration of scalability reinforces the value of this SSI prevention program.

Tracheostomy is a lifesaving, essential procedure performed for airway obstruction in the case of head and neck cancers, prolonged ventilator use, and for long-term pulmonary care. While successful quality improvement interventions in high-income countries such as through the Global Tracheostomy Collaborative significantly reduced length of hospital stay and decreased levels of anxiety among patients, limited literature exists regarding tracheostomy care and practices in low and middle-income countries (LMIC), where most of the world resides. Given limited literature, this scoping review aims to summarize published tracheostomy studies in LMICs and highlight areas in need of quality improvement and clinical research efforts. Based on the PRISMA guidelines, a scoping review of the literature was performed through MEDLINE/PubMed and Embase using terms related to tracheostomy, educational and quality improvement interventions, and LMICs. Publications from 2000-2022 in English were included. Eighteen publications representing 10 countries were included in the final analysis. Seven studies described baseline needs assessments, 3 development of training programs for caregivers, 6 trialed home-based or hospital-based interventions, and finally 2 articles discussed development of standardized protocols. Overall, studies highlighted the unique challenges to tracheostomy care in LMICs including language, literacy barriers, resource availability (running water and electricity in patient homes), and health system access (financial costs of travel and follow-up). There is currently limited published literature on tracheostomy quality improvement and care in LMICs. Opportunities to improve quality of care include increased efforts to measure complications and outcomes, implementing evidence-based interventions tailored to LMIC settings, and using an implementation science framework to study tracheostomy care in LMICs.

Capnography is now recognized as an indispensable patient safety monitor. Evidence suggests that its use improves outcomes in operating rooms, intensive care units, and emergency departments, as well as in sedation suites, in postanesthesia recovery units, and on general postsurgical wards. Capnography can accurately and rapidly detect respiratory, circulatory, and metabolic derangements. In addition to being useful for diagnosing and managing esophageal intubation, capnography provides crucial information when used for monitoring airway patency and hypoventilation in patients without instrumented airways. Despite its ubiquitous use in high-income-country operating rooms, deaths from esophageal intubations continue to occur in these contexts due to incorrect use or interpretation of capnography. National and international society guidelines on airway management mandate capnography’s use during intubations across all hospital areas, and recommend it when ventilation may be impaired, such as during procedural sedation. Nevertheless, capnography’s use across high-income-country intensive care units, emergency departments, and postanesthesia recovery units remains inconsistent. While capnography is universally used in high-income-country operating rooms, it remains largely unavailable to anesthesia providers in low- and middle-income countries. This lack of access to capnography likely contributes to more frequent and serious airway events and higher rates of perioperative mortality in low- and middle-income countries. New capnography equipment, which overcomes cost and context barriers, has recently been developed. Increasing access to capnography in low- and middle-income countries must occur to improve patient outcomes and expand universal health care. It is time to extend capnography’s safety benefits to all patients, everywhere.

Background

Gastroschisis causes near complete mortality in low-income countries (LICs). This study seeks to understand the impact of bedside bowel reduction and silo placement, and protocolized resuscitation on gastroschisis outcomes in LICs.

Methods

We conducted a retrospective cohort study of gastroschisis patients at a tertiary referral center in Kampala, Uganda. Multiple approaches for bedside application of bowel coverage devices and delayed closure were used: sutured urine bags (2017-2018), improvised silos using wound protectors (2020-2021), and spring-loaded silos (2022). Total parental nutrition (TPN) was not available; however, with the use of improvised silos, a protocol was implemented to include protocolized resuscitation and early enteral feeding. Risk ratios (RR) for mortality were calculated in comparison to historic controls from 2014.

Results

368 patients were included: 42 historic controls, 7 primary closures, 81 sutured urine bags, 133 improvised silos and 105 spring-loaded silos. No differences were found in sex (p = 0.31), days to presentation (p = 0.84), and distance traveled to the tertiary hospital (p = 0.16). Following the introduction of bowel coverage methods, the proportion of infants that survived to discharge increased from 2% to 16-29%. In comparison to historic controls, the risk of mortality significantly decreased: sutured urine bags 0.65 (95%CI: 0.52-0.80), improvised silo 0.76 (0.66-0.87), and spring-loaded silo 0.65 (0.56-0.76).

Conclusion

Bedside application of bowel coverage and protocolization decreases the risk of death for infants with gastroschisis, even in the absence of TPN. Further efforts to expand supply of low-cost silos in LICs would significantly decrease the mortality associated with gastroschisis in this setting.

Purpose

To address the need for a pediatric surgical checklist for adult providers.

Background

Pediatric surgery is unique due to the specific needs and many tasks that are employed in the care of adults require accommodations for children. There are some resources for adult surgeons to perform safe pediatric surgery and to assist such surgeons in pediatric emergencies, we created a straightforward checklist based on current literature. We propose a surgical checklist as the value of surgical checklists has been validated through research in a variety of applications.

Methods

Literature review on PubMed to gather information on current resources for pediatric surgery, all papers on surgical checklists describing their outcomes as of October 2022 were included to prevent a biased overview of the existing literature. Interviews with multiple pediatric surgeons were conducted for the creation of a checklist that is relevant to the field and has limited bias.

Results

42 papers with 8529061 total participants were included. The positive impact of checklists was highlighted throughout the literature in terms of outcomes, financial cost and team relationship. Certain care checkpoints emerged as vital checklist items: antibiotic administration, anesthetic considerations, intraoperative hemodynamics and postoperative resuscitation. The result was the creation of a checklist that is not substitutive for existing WHO surgery checklists but additive for adult surgeons who must operate on children in emergencies.

Conclusion

The outcomes measured throughout the literature are varied and thus provide both a nuanced view of a variety of factors that must be taken into account and are limited in the amount of evidence for each outcome. We hope to implement the checklist developed to create a standard of care for pediatric surgery performed in low resource settings by adult surgeons and further evaluate its impact on emergency pediatric surgery outcomes.

Background

Opportunities for residents to develop laparoscopic skills have decreased with the rise in robotic operations and the development of complex, subspecialized laparoscopic operations. Given the changing training landscape, this study aimed to identify laparoscopic surgeons’ perceptions of gaps in current laparoscopic skills in general surgery, obstetrics-gynecology, and urology residency programs.

Methods

Laparoscopic surgeons who operate with residents participated in semi-structured interviews. Questions addressed expectations for resident proficiency, deficits in laparoscopic surgical skills, and barriers to learning and teaching. Two authors independently coded de-identified transcripts followed by a conventional content analysis.

Results

Fourteen faculty members from thirteen subspecialties participated. Faculty identified three main areas to improve laparoscopic training across specialties: foundational knowledge, technical skills, and cognitive skills. They also recognized an overarching opportunity to address faculty development.

Conclusions

This qualitative study highlighted key deficiencies in laparoscopic training that have emerged in the current, changing era of minimally invasive surgery.

Key message

This qualitative study identified laparoscopic educators’ perceptions of deficiencies in laparoscopic training. Findings emphasized the importance of incorporating high quality educational practices to optimize training in the current changing landscape of laparoscopic surgery.

Background

Out-of-pocket healthcare costs leading to catastrophic healthcare expenditure pose a financial threat for families of children undergoing surgery in Sub-Saharan African countries, where universal healthcare coverage is often insufficient.

Methods

A prospective clinical and socioeconomic data collection tool was used in African hospitals with dedicated pediatric operating rooms installed philanthropically. Clinical data were collected via chart review and socioeconomic data from families. The primary indicator of economic burden was the proportion of families with catastrophic healthcare expenditures. Secondary indicators included the percentage who borrowed money, sold possessions, forfeited wages, and lost a job secondary to their child’s surgery. Descriptive statistics and multivariate logistic regression were performed to identify predictors of catastrophic healthcare expenditure.

Results

In all, 2,296 families of pediatric surgical patients from 6 countries were included. The median annual income was $1,000 (interquartile range 308-2,563), whereas the median out-of-pocket cost was $60 (interquartile range 26-174). Overall, 39.9% (n = 915) families incurred catastrophic healthcare expenditure, 23.3% (n = 533) borrowed money, 3.8% (n = 88%) sold possessions, 26.4% (n = 604) forfeited wages, and 2.3% (n = 52) lost a job because of the child’s surgery. Catastrophic healthcare expenditure was associated with older age, emergency cases, need for transfusion, reoperation, antibiotics, and longer length of stay, whereas the subgroup analysis found insurance to be protective (odds ratio 0.22, P = .002).

Conclusion

A full 40% of families of children in sub-Saharan Africa who undergo surgery incur catastrophic healthcare expenditure, shouldering economic consequences such as forfeited wages and debt. Intensive resource utilization and reduced insurance coverage in older children may contribute to a higher likelihood of catastrophic healthcare expenditure and can be insurance targets for policymakers.

Importance

A core component of delivering care of head and neck diseases is an adequate workforce. The World Health Organization report, Multi-Country Assessment of National Capacity to Provide Hearing Care, captured primary workforce estimates from 68 member states in 2012, noting that response rates were a limitation and that updated more comprehensive data are needed.

Objective

To establish comprehensive workforce metrics for global otolaryngology-head and neck surgery (OHNS) with updated data from more countries/territories.

Design, setting, and participants

A cross-sectional electronic survey characterizing the OHNS workforce was disseminated from February 10 to June 22, 2022, to professional society leaders, medical licensing boards, public health officials, and practicing OHNS clinicians.

Main outcome

The OHNS workforce per capita, stratified by income and region.

Results

Responses were collected from 121 of 195 countries/territories (62%). Survey responses specifically reported on OHNS workforce from 114 countries/territories representing 84% of the world’s population. The global OHNS clinician density was 2.19 (range, 0-61.7) OHNS clinicians per 100 000 population. The OHNS clinician density varied by World Bank income group with higher-income countries associated with a higher density of clinicians. Regionally, Europe had the highest clinician density (5.70 clinicians per 100 000 population) whereas Africa (0.18 clinicians per 100 000 population) and Southeast Asia (1.12 clinicians per 100 000 population) had the lowest. The OHNS clinicians deliver most of the surgical management of ear diseases and hearing care, rhinologic and sinus diseases, laryngeal disorders, and upper aerodigestive mucosal cancer globally.

Conclusion and relevance

This cross-sectional survey study provides a comprehensive assessment of the global OHNS workforce. These results can guide focused investment in training and policy development to address disparities in the availability of OHNS clinicians.
