Objectives

Children of minority background have reduced access to surgery. This study assessed for racial/ethnic differences in surgical utilization by location.

Materials and methods

We conducted a cross-sectional analysis of U.S. children (0-17 years of age) participating in the nationally representative Medical Expenditure Panel Survey (MEPS, 2015-2018). Race/ethnicity was the variable of interest. The primary outcome variables were prevalence rates of surgery defined by location of surgical procedure (inpatient, emergency department, hospital outpatient, and office). Covariates included contextual factors that may influence access to and need for healthcare services, including age, sex, insurance status, residential geographic status, usual source of care, and parental reports of child’s physical and mental health. We employed multivariate logistic regression models to assess the relationship between outcomes and race/ethnicity.

Results

The study population included 31,024 children with an overall surgical rate of 4.8%. Adjusted odds of surgery in an ambulatory location were lower for all racial/ethnic minority groups compared to non-Hispanic White counterparts (non-Hispanic Black aOR = 0.3, 95% CI: 0.2-0.5; Hispanic aOR = 0.4, 95% CI: 0.3-0.6; non-Hispanic Asian aOR = 0.2, 95% CI 0.0-0.5 for hospital outpatient surgery; for office-based setting, non-Hispanic Black aOR = 0.4, 95% CI 0.3-0.6; Hispanic aOR = 0.5, 95% CI: 0.4-0.7; non-Hispanic Asian aOR = 0.4; 95% CI 0.3-0.7). No racial/ethnic differences were observed for surgical procedures in inpatient or emergency department locations.

Conclusions

Staggering differences exist in pediatric surgery utilization patterns by racial/ethnic background, even after adjusting for important contextual factors (income, insurance, health status). Our findings in a nationally representative dataset may suggest systemic barriers related to racial/ethnic background for the pediatric surgical population.

Introduction

Racial and ethnic minority patients continue to experience disparities in health care. It is important to understand provider-level factors that may contribute to these inequities. This study aims to evaluate the presence of implicit racial bias among pediatric orthopaedic surgeons and determine the relationship between bias and clinical decision making.

Methods

A web-based survey was distributed to 415 pediatric orthopaedic surgeons. One section measured for potential implicit racial bias using a child-race implicit association test (IAT). IAT scores were compared with US physicians and the US general population using publicly available data. Another section consisted of clinical vignettes with associated questions. For each vignette, surgeons were randomly assigned a single race-version, White or Black. Vignette questions were grouped into an opioid recommendation, management decision, or patient perception category for analysis based on subject tested. Vignette answers from surgeons with IAT scores that were concordant with their randomized vignette race-version (ie, surgeon with pro-White score assigned White vignette version) were compared with those that were discordant.

Results

IAT results were obtained from 119 surveyed surgeons (29% response rate). Overall, respondents showed a minor pro-White implicit bias ( P <0.001). Implicit bias of any strength toward either race was present among 103/119 (87%) surgeons. The proportion of pediatric orthopaedic surgeons with a strong pro-White implicit bias (29%) was greater than that of US physicians overall (21%, P =0.032) and the US general population (19%, P =0.004). No differences were found in overall opioid recommendations, management decisions, or patient perceptions between concordant and discordant groups.

Conclusion

Most of the pediatric orthopaedic surgeons surveyed demonstrated implicit racial bias on IAT testing, with a large proportion demonstrating strong pro-White bias. Despite an association between implicit bias and clinical decision making in the literature, this study observed no evidence that implicit racial bias affected the management of pediatric fractures.

Background

Half the world’s population is at risk of catastrophic health expenditure (CHE, out-of-pocket spending of more than 10% of annual expenditure) should they require surgery. Protection against CHE is a key indicator of successful health care delivery and has been identified as a priority area by the Global Initiative for Children’s Surgery (GICS). Data specific to pediatric surgical patients is limited. This study examines the financial risks for pediatric surgical patients and their families from a provider’s perspective.

Methods

We surveyed GICS members about the existing financial protection mechanisms and estimated expenditures for their patients. Questions were structured based on the National Surgical, Obstetric and Anesthesia Planning Surgical Indicators and finalized based on multi-institutional consensus between high-income country and low-and middle-income country (LMIC) providers. Chi-squared test, Fisher’s exact test and student’s t-test were used as appropriate.

Results

Among 107 respondents, 72.4% were from low income or lower-middle income (LIC/LMIC) countries, and 55.1% were attending or consultant physicians. Families were most likely to decline surgery in LIC/LMIC due to inability to afford treatment (mean Likert = 3.77 ± 1.06). The odds of incurring CHE after children’s surgery are up to 17 times greater in LIC/LMIC (P = 0.001, unadjusted OR 17.28, 95%CI 2.13-140.02). Over 50% of families of children undergoing major surgery in these settings face CHE. An estimated 5.1% of providers in LIC/LMIC and 56.2% (P < 0.001) of providers in UMIC/HIC reported that families are able to pay for their direct medical costs with the assistance available to them and were more likely to sell assets (74.4% vs. 33.3%, P = 0.005).

Conclusion

Patients in LMICs are at greater risk for CHE and have less financial risk protection than their HIC counterparts. Given this disparity, intervention is needed to make safe surgery affordable for children worldwide.

Background

The impact of the COVID-19 pandemic on surgical care delivery in low- and middle-income countries (LMIC) has been challenging to assess due to a lack of data. This study examines the impact of COVID-19 on pediatric surgical volumes at four LMIC hospitals.

Methods

Retrospective and prospective pediatric surgical data collected at hospitals in Burkina Faso, Ecuador, Nigeria, and Zambia were reviewed from January 2019 to April 2021. Changes in surgical volume were assessed using interrupted time series analysis.

Results

6078 total operations were assessed. Before the pandemic, overall surgical volume increased by 21 cases/month (95% CI 14 to 28, p < 0.001). From March to April 2020, the total surgical volume dropped by 32%, or 110 cases (95% CI - 196 to - 24, p = 0.014). Patients during the pandemic were younger (2.7 vs. 3.3 years, p < 0.001) and healthier (ASA I 69% vs. 66%, p = 0.003). Additionally, they experienced lower rates of post-operative sepsis (0.3% vs 1.5%, p < 0.001), surgical site infections (1.3% vs 5.8%, p < 0.001), and mortality (1.6% vs 3.1%, p < 0.001).

Conclusions

During the COVID-19 pandemic, children’s surgery in LMIC saw a sharp decline in total surgical volume by a third in the month following March 2020, followed by a slow recovery afterward. Patients were healthier with better post-operative outcomes during the pandemic, implying a widening disparity gap in surgical access and exacerbating challenges in addressing the large unmet burden of pediatric surgical disease in LMICs with a need for immediate mitigation strategies.

The medical and surgical management of kidney stones is one of the most common functions of the urologist. Management choices are often nuanced, involving the decision to embark on one surgical plan among several options. As the wider medical community critically evaluates the care we provide to an increasingly diverse population, it will be important to examine patient outcomes with a particular focus on ensuring equitable care. This review examines the influence of social parameters on the care of kidney stone patients. The dearth of literature in this area warrants rigorous studies on the relationship between race as well as socioeconomic status and the management of kidney stone disease.

Background

One aim of publicly-funded health care systems is to provide equitable access to care irrespective of ability to pay. At the same time, differences in socioeconomic status (SES) are associated with health outcomes and access to care, including waiting times for surgery. In public systems where both high- and low-SES patients use the same resources, low-SES patients may be adversely impacted in surgical waiting times. The purpose of this study was to determine whether a publicly-funded health system can provide equitable access to surgical care across socioeconomic status.

Methods

Patient-level records were obtained from a comprehensive provincially-administered surgical wait time database, encompassing years 2006-2015 and 98% of Ontario hospitals. Patient SES was determined by linking postal code with the Material and Social Deprivation Index. Surgical waiting times (time in days between decision to treat and surgery) accounted for patient-initiated delays in treatment, and regression analysis considered age, SES, rurality, sex, priority level for surgical urgency (assigned by surgeons), surgical subspecialty, number of visits, and procedure year.

Results

For the 4,253,305 surgical episodes, the mean wait time was 62.3 (SD 75.4) days. Repeated measures least squares regression analysis showed the least deprived SES quintile waited 3 days longer than the most deprived quintile. Wait times dropped in the initial study period but then increased. The proportion of procedures exceeding wait time access targets remained low at 11-13%.

Conclusions

The least deprived SES quintile waited the longest, although the absolute difference was small. This study demonstrates that publicly-funded healthcare systems can provide equitable access to surgical care across SES.

Background

As surgical access expands in low- and middle-income countries, risk-adjusted outcomes data are needed to measure and improve surgical quality. Existing data collection tools in high-income countries are complex and may be burdensome to implement in low and middle income countries. This study determined the minimum dataset needed for adequate risk adjustment to predict perioperative mortality using data collected in a low- and middle-income countries.

Methods

All patients admitted to the pediatric surgery ward at Mulago National Referral Hospital in Kampala, Uganda, from January 1, 2014 through December 31, 2018 were included. Studies were performed modelling the effects of reducing data granularity and reducing number of variables on the area under the receiver operating curve.

Results

Of the 3,194 patients included, 1,941(61%) were male, 957(30%) were neonates, 1,714 (54%) had an operation, and the overall mortality rate was 14%. Granularity reduction analyses found that measuring age in ranges was equivalent to recording age in days (area under the receiver operating curve = 0.776; 95% confidence interval, 0.754%-0.798%, vs 0.815, 95% confidence interval, 0.794%-0.837%). Variable reduction analyses found that models with 3 predictor variables (diagnosis, procedure, and district) reached a maximum area under the receiver operating curve of 0.915 (95% confidence interval, 0.903%-0.928%), which was equivalent to the model using all available predictor variables (area under the receiver operating curve = 0.932; 95% confidence interval, 0.922%-0.943%). For all 3-variable models, the primary diagnosis contributed most to predictive ability (P < .001).

Conclusion

Effective risk adjustment for perioperative mortality can be performed in low and middle income countries using minimal, objective variables often already part of the patient’s medical record. This approach can be used by clinicians, hospital administrators, and policymakers low- and middle-income countries looking to begin data collection to track and improve patient outcomes.

Purpose of review

Although recent census demonstrates that women comprise 50.8% and ethnic minority groups collectively consist of 42.1% of the US population, the field of anesthesiology still demonstrates disparity in representation and health outcomes across race, ethnicity, and gender. In addition, the growing percentage of people that identify as lesbian, gay, bisexual, transgender, and queer (LGBTQ) compounded with limited representation among providers of their care can augment existing disparate outcomes within this community.

Recent findings

Compared to male colleagues, women physicians across all specialties have a decreased likelihood of professorship as well as equitable pay and leadership roles. Additionally, a 2019 study of anesthesia residents across race and ethnicity within the Accreditation Council for Graduate Medical Education established that whites were 58.9%, Asians were 24.7%, Hispanics were 7.8%, Blacks were 5.9%, multiracial groups were 3.8%, and Native Americans were 0.3% of the total 6272 residents. In a survey of members of the American Society of Anesthesiologists, self-identification as part of the sexual and gender minoritycommunity was independently associated with an increased risk of burnout. Furthermore, teams with higher diversity in cognitive styles solve problems more efficiently.

Summary

To achieve an optimized quality of healthcare, anesthesiologists and other providers should be a reflection of the communities they serve, including women, people of color, and LGBTQ. In this way, there is an increased likelihood of empathy, effective communication, and insightful perspectives on how to bridge the gap in health equity. A diverse lens is essential to ensure grassroots efforts lead to lasting transformational change.

The rapid pace of the COVID-19 pandemic precluded traditional approaches to evaluating clinical research and guidelines. We highlight notable successes and pitfalls of clinicians’ new approaches to managing evidence amidst an unprecedented crisis. In “Era 1” (early 2020), clinicians relied on anecdote and social media, which democratized conversations on guidelines, but also led clinicians astray. “Era 2” (approximately late 2020 to early 2021) saw preprints that accelerated new interventions but suffered from a surfeit of poor-quality data. In the current era, clinicians consolidate the evidentiary gains of Era 2 with living, online clinical guidelines, but the public suffers from misinformation. The COVID-19 pandemic is a laboratory on how clinicians adapt to an absence of clinical guidance amidst an informational and healthcare crisis. Challenges remain as we integrate new approaches to innovations made in the traditional guideline process to confront both the long tail of COVID-19 and future pandemics.

It has long been known that many pulse oximeters function less accurately in patients with darker skin. Reasons for this observation are incompletely characterized and potentially enabled by limitations in existing regulatory oversight. Based on decades of experience and unpublished data, we believe it is feasible to fully characterize, in the public domain, the factors that contribute to missing clinically important hypoxemia in patients with darkly pigmented skin. Here we propose 5 priority areas of inquiry for the research community and actionable changes to current regulations that will help improve oximeter accuracy. We propose that leading regulatory agencies should immediately modify standards for measuring accuracy and precision of oximeter performance, analyzing and reporting performance outliers, diversifying study subject pools, thoughtfully defining skin pigmentation, reporting data transparently, and accounting for performance during low-perfusion states. These changes will help reduce bias in pulse oximeter performance and improve access to safe oximeters.

The Earth’s mean surface temperature is already approximately 1.1°C higher than pre-industrial levels. Exceeding a mean 1.5°C rise by 2050 will make global adaptation to the consequences of climate change less possible. To protect public health, anaesthesia providers need to reduce the contribution their practice makes to global warming. We convened a Working Group of 45 anaesthesia providers with a recognised interest in sustainability, and used a three-stage modified Delphi consensus process to agree on principles of environmentally sustainable anaesthesia that are achievable worldwide. The Working Group agreed on the following three important underlying statements: patient safety should not be compromised by sustainable anaesthetic practices; high-, middle- and low-income countries should support each other appropriately in delivering sustainable healthcare (including anaesthesia); and healthcare systems should be mandated to reduce their contribution to global warming. We set out seven fundamental principles to guide anaesthesia providers in the move to environmentally sustainable practice, including: choice of medications and equipment; minimising waste and overuse of resources; and addressing environmental sustainability in anaesthetists’ education, research, quality improvement and local healthcare leadership activities. These changes are achievable with minimal material resource and financial investment, and should undergo re-evaluation and updates as better evidence is published. This paper discusses each principle individually, and directs readers towards further important references.

Objective

To determine if limited food access census tracts and food swamp census tracts are associated with increased risk for repeat kidney stone surgery. And to elucidate the relationship between community-level food retail environment relative to community-level income on repeat stone surgery over time.

Methods

Data were abstracted from the University of California, San Francisco Information Commons. Adult patients were included if they underwent at least one urologic stone procedure. Census tracts from available geographical data were mapped using Food Access Research Atlas data from the United States Department of Agriculture Economic Research Service. Kaplan-Meier curves were employed to illustrate time to a second surgical procedure over 5 years, and log-rank tests were used to test for statistically significant differences. A multivariate Cox regression model was used to generate hazard ratios for undergoing second surgery by group.

Results

A total of 1496 patients were included in this analysis. Repeat stone surgery occurred in 324 patients. Kaplan-Meier curves demonstrated a statistically significant difference in curves depicting patients living in low income census tracts (LICTs) vs those not living in LICTs (P <.001). On Cox regression models, patients in LICTs had significantly higher risk of undergoing repeat surgery (P = .011). Patients from limited food access census tracts and food swamp census tracts did not have a significantly higher adjusted risk of undergoing second surgery (P = .11 and P = .88, respectively).

Conclusion

Income more so than food access associates with increased risk of repeat kidney stone surgery. Further research is needed to explore the interaction between low socioeconomic status and kidney stone outcomes.

Background

On average, a person living in San Francisco can expect to live 83 years. This number conceals significant variation by sex, race, and place of residence. We examined deaths and area-based social factors by San Francisco neighborhood, hypothesizing that socially disadvantaged neighborhoods shoulder a disproportionate mortality burden across generations, especially deaths attributable to violence and chronic disease. These data will inform targeted interventions and guide further research into effective solutions for San Francisco’s marginalized communities.

Study design

The San Francisco Department of Public Health provided data for the 2010-2014 top 20 causes of premature death by San Francisco neighborhood. Population-level demographic data were obtained from the US American Community Survey 2015 5-year estimate (2011-2015). The primary outcome was the association between years of life loss (YLL) and adjusted years of life lost (AYLL) for the top 20 causes of death in San Francisco and select social factors by neighborhood via linear regression analysis and heatmaps.

Results

The top 20 causes accounted for N = 15,687 San Francisco resident deaths from 2010-2014. Eight neighborhoods (21.0%) accounted for 47.9% of city-wide YLLs, with 6 falling below the city-wide median household income and many having a higher percent population Black, and lower education and higher unemployment levels. For chronic diseases and homicides, AYLLs increased as a neighborhood’s percent Black, below poverty level, unemployment, and below high school education increased.

Conclusions

Our study highlights the mortality inequity burdening socially disadvantaged San Francisco neighborhoods, which align with areas subjected to historical discriminatory policies like redlining. These data emphasize the need to address past injustices and move toward equal access to wealth and health for all San Franciscans.

Capnometry, the measurement of respiratory carbon dioxide, is regarded as a highly recommended safety technology in intubated and nonintubated sedated and/or anesthetized patients. Its utility includes confirmation of initial and ongoing placement of an airway device as well as in detecting gas exchange, bronchospasm, airway obstruction, reduced cardiac output, and metabolic changes. The utility applies prehospital and throughout all phases of inhospital care. Unfortunately, capnometry devices are not readily available in many countries, especially those that are resource-limited. Constraining factors include cost, durability of devices, availability of consumables, lack of dependable power supply, difficulty with cleaning, and maintenance. There is, thus, an urgent need for all stakeholders to come together to develop, market, and distribute appropriate devices that address costs and other requirements. To foster this process, the World Federation of Societies of Anaesthesiologists (WFSA) has developed the “WFSA-Minimum Capnometer Specifications 2021.” The intent of the specifications is to set the minimum that would be acceptable from industry in their attempts to reduce costs while meeting other needs in resource-constrained regions. The document also includes very desirable and preferred options. The intent is to stimulate interest and engagement among industry, clinical providers, professional associations, and ministries of health to address this important patient safety need. The WFSA-Minimum Capnometer Specifications 2021 is based on the International Organization for Standardization (ISO) capnometer specifications. While industry is familiar with such specifications and their presentation format, most clinicians are not; therefore, this article serves to more clearly explain the requirements. In addition, the specifications as described can be used as a purchasing guide by clinicians.

Introduction

We aimed to search the literature for global surgical curricula, assess if published resources align with existing competency frameworks in global health and surgical education, and determine if there is consensus around a fundamental set of competencies for the developing field of academic global surgery.

Methods

We reviewed SciVerse SCOPUS, PubMed, African Medicus Index, African Journals Online (AJOL), SciELO, Latin American and Caribbean Health Sciences Literature (LILACS) and Bioline for manuscripts on global surgery curricula and evaluated the results using existing competency frameworks in global health and surgical education from Consortium of the Universities for Global Health (CUGH) and Accreditation Council for Graduate Medical Education (ACGME) professional competencies.

Our search generated 250 publications, of which 18 were eligible: (1) a total of 10 reported existing competency-based curricula that were concurrent with international experiences, (2) two reported existing pre-departure competency-based curricula, (3) six proposed theoretical competency-based curricula for future global surgery education. All, but one, were based in high-income countries (HICs) and focused on the needs of HIC trainees. None met all 17 competencies, none cited the CUGH competency on “Health Equity and Social Justice” and only one mentioned “Social and Environmental Determinants of Health.” Only 22% (n = 4) were available as open-access.

Conclusion

Currently, there is no universally accepted set of competencies on the fundamentals of academic global surgery. Existing literature are predominantly by and for HIC institutions and trainees. Current frameworks are inadequate for this emerging academic field. The field needs competencies with explicit input from LMIC experts to ensure creation of educational resources that are accessible and relevant to trainees from around the world.

Background

Significant limitations in pediatric surgical capacity exist in low- and middle-income countries, especially in rural regions. Recent global children’s surgical guidelines suggest training and support of general surgeons in rural regional hospitals as an effective approach to increasing pediatric surgical capacity.

Methods

Two years of a prospective clinical database of children’s surgery admissions at 2 regional referral hospitals in Uganda were reviewed. Primary outcomes included case volume and clinical outcomes of children at each hospital. Additionally, the disability-adjusted life-years averted by delivery of pediatric surgical services at these hospitals were calculated. Using a value of statistical life calculation, we also estimated the economic benefit of the pediatric surgical care currently being delivered.

Results

From 2016 to 2019, more than 300 surgical procedures were performed at each hospital per year. The majority of cases were standard general surgery cases including hernia repairs and intussusception as well as procedures for surgical infections and trauma. In-hospital mortality was 2.4% in Soroti and 1% in Lacor. Pediatric surgical capacity at these hospitals resulted in over 12,400 disability-adjusted life-years averted/year. This represents an estimated economic benefit of 10.2 million US dollars/year to the Ugandan society.

Conclusion

This investigation demonstrates that lifesaving pediatric procedures are safely performed by general surgeons in Uganda. General surgeons who perform pediatric surgery significantly increase surgical access to rural regions of the country and add a large economic benefit to Ugandan society. Overall, the results of the study support increasing pediatric surgical capacity in rural areas of low- and middle-income countries through support and training of general surgeons and anesthesia providers.

Background

Indicators to evaluate progress towards timely access to safe surgical, anaesthesia, and obstetric (SAO) care were proposed in 2015 by the Lancet Commission on Global Surgery. These aimed to capture access to surgery, surgical workforce, surgical volume, perioperative mortality rate, and catastrophic and impoverishing financial consequences of surgery. Despite being rapidly taken up by practitioners, data points from which to derive the indicators were not defined, limiting comparability across time or settings. We convened global experts to evaluate and explicitly define-for the first time-the indicators to improve comparability and support achievement of 2030 goals to improve access to safe affordable surgical and anaesthesia care globally.

Methods and findings

The Utstein process for developing and reporting guidelines through a consensus building process was followed. In-person discussions at a 2-day meeting were followed by an iterative process conducted by email and virtual group meetings until consensus was reached. The meeting was held between June 16 to 18, 2019; discussions continued until August 2020. Participants consisted of experts in surgery, anaesthesia, and obstetric care, data science, and health indicators from high-, middle-, and low-income countries. Considering each of the 6 indicators in turn, we refined overarching descriptions and agreed upon data points needed for construction of each indicator at current time (basic data points), and as each evolves over 2 to 5 (intermediate) and >5 year (full) time frames. We removed one of the original 6 indicators (one of 2 financial risk protection indicators was eliminated) and refined descriptions and defined data points required to construct the 5 remaining indicators: geospatial access, workforce, surgical volume, perioperative mortality, and catastrophic expenditure. A strength of the process was the number of people from global institutes and multilateral agencies involved in the collection and reporting of global health metrics; a limitation was the limited number of participants from low- or middle-income countries-who only made up 21% of the total attendees.

Conclusions

To track global progress towards timely access to quality SAO care, these indicators-at the basic level-should be implemented universally as soon as possible. Intermediate and full indicator sets should be achieved by all countries over time. Meanwhile, these evolutions can assist in the short term in developing national surgical plans and collecting more detailed data for research studies.

  • Anesthesia
  • Workforce

Background

One of the biggest barriers to accessing safe surgical and anesthetic care is lack of trained providers. Uganda has one of the largest deficits in anesthesia providers in the world, and though they are increasing in number, they remain concentrated in the capital city. Salary is an oft-cited barrier to rural job choice, yet the size and sources of anesthesia provider incomes are unclear, and so the potential income loss from taking a rural job is unknown. Additionally, while salary augmentation is a common policy proposal to increase rural job uptake, the relative importance of non-monetary job factors in job choice is also unknown.

Methods

A survey on income sources and magnitude, and a Discrete Choice Experiment examining the relative importance of monetary and non-monetary factors in job choice, was administered to 37 and 47 physician anesthesiologists in Uganda, between May-June 2019.

Results

No providers worked only at government jobs. Providers earned most of their total income from a non-government job (50% of income, 23% of working hours), but worked more hours at their government job (36% of income, and 44% of working hours). Providers felt the most important job attributes were the quality of the facility and scope of practice they could provide, and the presence of a colleague (33% and 32% overall relative importance). These were more important than salary and living conditions (14% and 12% importance).

Conclusions

No providers accepted the salary from a government job alone, which was always augmented by other work. However, few providers worked only nongovernment jobs. Non-monetary incentives are powerful influencers of job preference, and may be leveraged as policy options to attract providers. Salary continues to be an important driver of job choice, and jobs with fewer income generating opportunities (e.g. private work in rural areas) are likely to need salary augmentation to attract providers.

About 1.7 billion children and adolescents, mostly in low- and middle-income countries (LMICs) lack access to surgical care. While some of these countries have developed surgical plans and others are in the process of developing theirs, children’s surgery has not received the much-needed specific emphasis and focus in these plans. With the significant burden of children’s surgical conditions especially in low- and middle-income countries, universal health coverage and the United Nations’ (UN) Sustainable Development Goals (SDG) will not be achieved without deliberate efforts to scale up access to children’s surgical care. Inclusion of children’s surgery in National Surgical Obstetric and Anaesthesia Plans (NSOAPs) can be done using the Global Initiative for Children’s Surgery (GICS)-modified Children’s Surgical Assessment Tool (CSAT) tool for baseline assessment and the Optimal Resources for Children Surgical Care (OReCS) as a foundational tool for implementation.

Background

The standard method of sharing information in academia is the scientific journal. Yet health advocacy requires alternative methods to reach key stakeholders to drive change. The purpose of this study was to analyze the impact of social media and public narrative for advocacy in matters of firearm-related injury and death.

Study design

The movement This Is Our Lane was evaluated through the #ThisIsOurLane and #ThisIsMyLane hashtags. Sources were assessed from November 2018 through March 2019. Analyses specifically examined message volume, time course, global engagement, and content across Twitter, scientific literature, and mass media. Twitter data were analyzed via Symplur Signals. Scientific literature reviews were performed using PubMed, EMBASE, Web of Science, and Google Scholar. Mass media was compiled using Access World News/Newsbank, Newspaper Source, and Google.

Results

A total of 507,813 tweets were shared using #ThisIsOurLane, #ThisIsMyLane, or both (co-occurrence 21-39%). Fifteen scientific items and n = 358 mass media publications were published during the study period; the latter included articles, blogs, television interviews, petitions, press releases, and audio interviews/podcasts. Peak messaging appeared first on Twitter on November 10th, followed by mass media on November 12th and 20th, and scientific publications during December.

Conclusions

Social media enables clinicians to quickly disseminate information about a complex public health issue like firearms to the mainstream media, scientific community, and general public alike. Humanized data resonates with people and has the ability to transcend the barriers of language, culture, and geography. Showing society the reality of caring for firearm-related injuries through healthcare worker stories via digital media appears to be effective in shaping the public agenda and influencing real-world events.

Background

Low- and middle-income countries like Uganda face a severe shortage of pediatric surgeons. Most children with a surgical emergency are treated by nonspecialist rural providers. We describe the design and implementation of a locally driven, pilot pediatric emergency surgical care course to strengthen skills of these providers. This is the first description of such a course in the current literature.

Methods

The course was delivered three times from 2018 to 2019. Modules include perioperative management, neonatal emergencies, intestinal emergencies, and trauma. A baseline needs assessment survey was administered. Participants in the second and third courses also took pre and postcourse knowledge-based tests.

Results

Forty-five providers representing multiple cadres participated. Participants most commonly perform hernia/hydrocele repair (17% adjusted rating) in their current practice and are least comfortable managing cleft lip and palate (mean Likert score 1.4 ± 0.9). Equipment shortage was identified as the most significant challenge to delivering pediatric surgical care (24%). Scores on the knowledge tests improved significantly from pre- (55.4% ± 22.4%) to postcourse (71.9% ± 14.0%, p < 0.0001).

Conclusion

Nonspecialist clinicians are essential to the pediatric surgical workforce in LMICs. Short, targeted training courses can increase provider knowledge about the management of surgical emergencies. The course has spurred local surgical outreach initiatives. Further implementation studies are needed to evaluate the impact of the training.

Lack of access to urologic specialists is approaching crisis levels as the number of urologists is decreasing, while the demand for urologic care is increasing. The financial implications of this have not been explored. The objective of this study is to examine the impact of access and other patient factors on cost to treat urolithiasis. We hypothesized that markers of poor access would associate with higher costs of surgical encounters for patients presenting with urolithiasis. A retrospective review of prospectively collected data from the Registry for Stones of the Kidney and Ureter (ReSKU) from September 2015 to July 2018 was conducted to investigate characteristics of surgical patients treated for urinary stone disease. Univariate analysis was performed using the Welch two-sample -test. Multivariate analysis was performed using logistic regression. Statistical analysis was performed in R version 3.5. When taking into account age, delayed presentation, procedure type, stone size >20 mm, American Society of Anesthesiologists (ASA) code, gender, race, income, distance, urologist density, body mass index, diabetes, infection, education, language, insurance, and stone complexity, patients undergoing percutaneous nephrolithotomy procedure ( < 0.001; odds ratio [OR] 12.9, confidence interval [CI] 4.05-48.5), urologist density in the bottom quartile ( = 0.014; OR 4.66, CI 1.40-16.9), diabetes ( = 0.018; OR 4.38, CI 1.32-15.6), and infection ( = 0.007; OR 4.51, CI 1.55-14.0) were the only variables statistically significant for association with top quartile of total cost. Surgical encounter costs are largely dictated by patient clinical factors, but low regional urologist density appears to independently predicted for high-cost stone surgery. Increasing patients' access to a urologist may prove to be financially beneficial in the longitudinal reduction in health care costs for stone disease.

Background

Gluteal fibrosis (GF) is a fibrotic infiltration of the gluteal muscles resulting in functionally limiting contracture of the hips and is associated with injections of medications into the gluteal muscles. It has been reported in numerous countries throughout the world. This study assesses the 5-year postoperative range of motion (ROM) and functional outcomes for Ugandan children who underwent surgical release of GF.

Methods

A retrospective cohort study of children who underwent release of GF in 2013 at Kumi Hospital in Eastern Uganda. Functional outcomes, hip ROM, and scar satisfaction data were collected for all patients residing within 40 km of the hospital.

Results

One hundred eighteen children ages 4 to 16 at the time of surgery were treated with surgical release of GF in 2013 at Kumi Hospital. Of those 118, 89 were included in this study (79.5%). The remaining 29 were lost to follow-up or lived outside the study’s radius. Detailed preoperative ROM and functional data were available for 53 of the 89 patients. In comparison with preoperative assessment, all patients postoperatively reported ability to run normally (P<0.001), sit upright in a chair (P<0.001), sit while eating (P<0.001), and attend the entire day of school (P<0.001). Passive hip flexion (P<0.001) improved when compared with preoperative measurements. In all, 85.2% (n=75) of patients reported satisfaction with scar appearance as "ok," "good," or "excellent" 29.2% (n=26) of patients reported back or hip complaints.

Conclusions

Overall, the 5-year postoperative outcomes suggest that surgical release of GF improves ROM and functional quality of life with sustained effect.

Background

Trauma is a major global health problem and majority of the deaths occur in low- and middle-income countries (LMICs), at even higher rates in the rural areas. The three-delay model assesses three different delays in accessing healthcare and can be applied to improve surgical and trauma healthcare delivery. Prior to implementing change, the capacities of the rural India healthcare system need to be identified.

Objective

The object of this study was to estimate surgical and trauma care capacities of government health facilities in rural Nanakpur, Haryana, India using the Personnel, Infrastructure, Procedures, Equipment and Supplies (PIPES) and International Assessment of Capacity for Trauma (INTACT) tools.

Methods

The PIPES and INTACT tools were administered at eight government health facilities serving the population of Nanakpur in June 2015. Data analysis was performed per tool subsection, and an overall score was calculated. Higher PIPES or INTACT indices correspond to greater surgical or trauma care capacity, respectively.

Findings

Surgical and trauma care capacities increased with higher levels of care. The median PIPES score was significantly higher for tertiary facilities than primary and secondary facilities [13.8 (IQR 9.5, 18.2) vs. 4.7 (IQR 3.9, 6.2), p = 0.03]. The lower-level facilities were mainly lacking in personnel and procedures.

Conclusions

Surgical and trauma care capacities at healthcare facilities in Haryana, India demonstrate a shortage of surgical resources at lower-level centers. Specifically, the Primary Health Centers were not operating at full capacity. These results can inform resource allocation, including increasing education, across different facility levels in rural India.
