Project SPRUCE: Saving Our Planet by Reducing Carbon Emissions, a Pediatric Anesthesia Sustainability Quality Improvement Initiative.

BACKGROUND: Children are particularly vulnerable to adverse health outcomes related to climate change. Inhalational anesthetics are potent greenhouse gasses (GHGs) and contribute significantly to health care-generated emissions. Desflurane and nitrous oxide have very high global warming potentials. Eliminating their use, as well as lowering fresh gas flows (FGFs), will lead to reduced emissions. METHODS: Using published calculations for converting volatile anesthetic concentrations to carbon dioxide equivalents (CO 2 e), we derived the average kilograms (kg) CO 2 e/min for every anesthetic administered in the operating rooms at our pediatric hospital and ambulatory surgical center between October 2017 and October 2022. We leveraged real-world data captured from our electronic medical record systems and used AdaptX to extract and present those data as statistical process control (SPC) charts. We implemented recommended strategies aimed at reducing emissions from inhalational anesthetics, including removing desflurane vaporizers, unplugging nitrous oxide hoses, decreasing the default anesthesia machine FGF, clinical decision support tools, and educational initiatives. Our primary outcome measure was average kg CO 2 e/min. RESULTS: A combination of educational initiatives, practice constraints, protocol changes, and access to real-world data were associated with an 87% reduction in measured GHG emissions from inhaled anesthesia agents used in the operating rooms over a 5-year period. Shorter cases (<30 minutes duration) had 3 times higher average CO 2 e, likely due to higher FGF and nitrous oxide use associated with inhalational inductions, and higher proportion of mask-only anesthetics. Removing desflurane vaporizers corresponded with a >50% reduction of CO 2 e. A subsequent decrease in anesthesia machine default FGF was associated with a similarly robust emissions reduction. Another significant decrease in emissions was noted with educational efforts, clinical decision support alerts, and feedback from real-time data. CONCLUSIONS: Providing environmentally responsible anesthesia in a pediatric setting is a challenging but achievable goal, and it is imperative to help mitigate the impact of climate change. Large systems changes, such as eliminating desflurane, limiting access to nitrous oxide, and changing default anesthesia machine FGF rates, were associated with rapid and lasting emissions reduction. Measuring and reporting GHG emissions from volatile anesthetics allows practitioners to explore and implement methods of decreasing the environmental impact of their individual anesthesia delivery practices.

The Global Initiative for Children's Surgery: conception, gestation, and delivery.

More than two thirds of the global population lack access to safe, affordable surgical and anesthesia care. This inequity disproportionately affects children in low- and middle-income countries (LMIC). In 2016, a group of pediatric surgical care providers founded the Global Initiative for Children's Surgery (GICS). Their goal was to assemble a multidisciplinary team of specialists and advocates to improve surgical care for children, with a particular emphasis on those in low-resource settings. This review details the history of GICS, the process of its inception, the values guiding its work, its past achievements, and its current initiatives. The experience of GICS may serve as an effective model for global collaboration on other areas of public and global health.

Potentially Avertable Child Mortality Associated with Surgical Workforce Scale-up in Low- and Middle-Income Countries: A Global Study.

BACKGROUND: Expansion of access to surgical care can improve health outcomes, although the impact that scale-up of the surgical workforce will have on child mortality is poorly defined. In this study, we estimate the number of child deaths potentially avertable by increasing the surgical workforce globally to meet targets proposed by the Lancet Commission on Global Surgery. METHODS: To estimate the number of deaths potentially avertable through increases in the surgical workforce, we used log-linear regression to model the association between surgeon, anesthetist and obstetrician workforce (SAO) density and surgically amenable under-5 mortality rate (U5MR), infant mortality rate (IMR), and neonatal mortality rate (NMR) for 192 countries adjusting for potential confounders of childhood mortality, including the non-surgical workforce (physicians, nurses/midwives, community health workers), gross national income per capita, poverty rate, female literacy rate, health expenditure per capita, percentage of urban population, number of surgical operations, and hospital bed density. Surgically amenable mortality was determined using mortality estimates from the UN Inter-agency Group for Child Mortality Estimation adjusted by the proportion of deaths in each country due to communicable causes unlikely to be amenable to surgical care. Estimates of mortality reduction due to upscaling surgical care to support the Lancet Commission on Global Surgery (LCoGS) minimum target of 20-40 SAO/100,000 were calculated accounting for potential increases in surgical volume associated with surgical workforce expansion. RESULTS: Increasing SAO workforce density was independently associated with lower surgically amenable U5MR as well as NMR (p < 0.01 for each model). When accounting for concomitant increases in surgical volume, scale-up of the surgical workforce to 20-40 SAO/100,000 could potentially prevent between 262,709 (95% CI 229,643-295,434) and 519,629 (465,046-573,919) under 5 deaths annually. The majority (61%) of deaths averted would be neonatal deaths. CONCLUSION: Scale up of surgical workforce may substantially decrease childhood mortality rates around the world. Our analysis suggests that scale-up of surgical delivery through increase in the SAO workforce could prevent over 500,000 children from dying before the age of 5 annually. This would represent significant progress toward meeting global child mortality reduction targets.

The global blood supply: a literature review.

BACKGROUND: A safe and sufficient blood supply is requisite for a functional surgical system. Although the disparity in blood donation rates between low-income and middle-income countries (LMICs) and high-income countries is well documented, less is known about the reasons for this inequity, which compromises efforts to remedy it. We aimed to review the state of the blood supply and elucidate unique country-specific challenges in each of the world's 196 countries. METHODS: We searched PubMed, MEDLINE, Google Scholar, and WHO reports using the search terms "blood donor", "blood donation","blood safety", "blood bank", "transfusion safety", and "blood services". After an initial review of existing literature, we did a comprehensive country-by-country search of the aforementioned electronic databases, WHO regional reports, Ministry of Health websites, and National Blood Transfusion Services data for specific indicators and data points used to compare blood supply and safety across countries. These included donation rate per 1000 population, percent of donations from voluntary non-remunerated donors, number of blood banks or centres, and national blood policies. Both quantitative and descriptive data are included in a summary table in the appendix of the Lancet Commission on Global Surgery. FINDINGS: Our review yielded 117 publications with data for 188 countries: 101 peer-reviewed manuscripts with 13 reporting data for high-income countries and 88 for LMICs, 16 WHO publications, and a subsequent search of select websites to collect additional country-specific indicator data. Generally, blood donation is limited because of poor health infrastructure (28 LMIC and four high-income country manuscripts), low public awareness of donation practices and safety (22 LMIC manuscripts), and stigmas surrounding voluntary blood donations, especially in LMICs. Most blood banks and donation centres are located in urban centres, inaccessible to those in rural areas. The prevalence of transfusion-transmissible infections in the blood supply is higher in LMICs (30 LMIC manuscripts), resulting in high discard rates and increased transfusion risks. Two-thirds of countries have a national blood policy in place, but are often unable to efficiently coordinate and regulate blood services nationwide. To overcome these barriers, some countries have developed innovative solutions. INTERPRETATION: The blood supply in LMICs is of insufficient quantity and safety, and the reasons for these deficits are multifactorial. Addressing blood supply inadequacies requires focused attention at both local and global levels. Political prioritisation and innovative solutions to the blood crisis will be necessary to improve this situation and will require a culturally cognizant, pro-poor, pro-equity approach. Reviewing successful approaches to this crisis employed by some countries can be helpful in charting a way forward. FUNDING: None.

Out-of-pocket expenses incurred by patients obtaining free breast cancer care in Haiti.

BACKGROUND: Women with breast cancer in low-income and middle-income countries (LMICs) account for 51% of cases globally and often present with advanced disease. Fear of costs contributes to delay in seeking care, as health expenditures are financially catastrophic for families worldwide. Despite efforts to improve affordability of health care in LMICs, the financial burden of indirect costs (eg, transportation and lost wages) is often overlooked. We aimed to identify and quantify the expenditures of patients seeking breast cancer care in a LMIC. METHODS: Patients receiving breast cancer care free of charge at Hôpital Universitaire de Mirebalais (HUM) in Haiti were interviewed to quantify their costs and assess the effect of these costs on patients and families. These costs included expenses for food, lodging, transportation, childcare, medical costs at other institutions, and lost wages. 61 patients were interviewed during diagnostic, chemotherapy, and surgical visits between March 1, and May 12, 2014. Institutional review board exemption was granted from Boston Children's Hospital and Partners in Health/Zanmi Lasante. FINDINGS: The median non-medical out-of-pockent expenses incurred by breast cancer patients at HUM were US$233 (95% CI 170-304) for diagnostic visits, US$259 (95% CI 200-533) for chemotherapy, and US$38 (95% CI 23-140) for surgery. The median total out-of-pockent expense (including medical costs) was US$717 (95% CI 619-1171). These costs forced 52% of participants into debt and 20% to sell possessions. The median percentage of potential individual income spent on out-of-pocket costs was 60%. The median sum of out-of-pocket costs and lost wages was US$2996 (95% CI 1676-5179). INTERPRETATION: In Haiti, 74% of people earn less than US$2 per day. Even when breast cancer treatment is provided for free, out-of-pocket expenses could account for more than 91% of annual earnings at this income level. This financial burden is an overwhelming obstacle for Haiti's poorest citizens, and probably for many patients in LMICs. High-powered, multisite studies are needed to further characterise this burden worldwide. Funders and health-care providers should reduce indirect costs to achieve equitable access to oncology care.

A qualitative study exploring contextual challenges to surgical care provision in 21 LMICs.

BACKGROUND: Billions of people worldwide are without access to safe, affordable, and timely surgical care. The Lancet Commission on Global Surgery (LCoGS) conducted a qualitative study to understand the contextual challenges to surgical care provision in low-income and middle-income countries (LMICs), and how providers overcome them. METHODS: A semi-structured interview was administered to 143 care providers in 21 LMICs using stratified purposive sampling to include both urban and rural areas and reputational case selection to identify individual providers. Interviews were conducted in Argentina (n=5), Botswana (3), Brazil (10), Cape Verde (4), China (14), Colombia (4), Ecuador (6), Ethiopia (10), India (15), Indonesia (1), Mexico (9), Mongolia (4), Namibia (2), Pakistan (13), Peru (5), Philippines (1), Sierra Leone (11), Tanzania (5), Thailand (2), Uganda (9), and Zimbabwe (15). Local collaborators of LCoGS conducted interviews using a standardised implementation manual and interview guide. Questions revolved around challenges or barriers in the area of access to care for patients; challenges or barriers in the area of in-hospital care for patients; and challenges or barriers in the area of governance or health policy. De-identified interviews were coded and interpreted by an independent analyst. FINDINGS: Providers across continent and context noted significant geographical, financial, and educational barriers to access. Surgical care provision in the rural hospital setting was hindered by a paucity of trained workforce, and inadequacies in basic infrastructure, equipment, supplies, and access to banked blood. In urban areas, providers face high patient volumes combined with staff shortages, minimal administrative support, and poor interhospital care coordination. At a policy level, providers identified regulations that were inconsistent with the realities of low-resource care provision (eg, a requirement to provide 'free' care to certain populations but without any guarantee for funding). Regional variation did exist on some matters, particularly related to prevalence of patient-provider mistrust and supply chain failures. Everywhere, providers have created innovative workarounds to overcome some of these barriers, such as clever financing mechanisms for planned surgery (eg, raising donated farm animals for cash in Zimbabwe, Ethiopia, and India), provision in scheduling and accommodations to facilitate patients from afar, reduction of cost and waste through re-sterilisation of disposable supplies, and locally sourcing consumables (eg, hand cleaning solution made of alcohol from the local distillery in India). INTERPRETATION: Although some variation exists between countries, the challenges to surgical care provision are largely consistent and based on local resource availability; underfunded rural hospitals faced similar challenges worldwide. Global efforts to scale-up surgical services can focus on these commonalities (eg, investments in infrastructure, workforce), while local governments can tailor solutions to key contextual differences (eg, community-based outreach, supply chains, professional management, and interhospital coordination).

Use and definitions of perioperative mortality rates in low-income and middle-income countries: a systematic review.

BACKGROUND: Aggregate and risk-stratified perioperative mortality rates (POMR) are well-documented in high-income countries where surgical databases are common. In many low-income and middle-income country (LMIC) settings, such data are unavailable, compromising efforts to understand and improve surgical outcomes. We undertook a systematic review to determine how POMR is used and defined in LMICs and to inform baseline rates. METHODS: We searched PubMed for all articles published between Jan 1, 2009, and Sept 1, 2014, reporting surgical mortality in LMICs. Search criteria, inclusion and exclusion criteria, and study assessment methodology are reported in the appendix. Titles and abstracts were screened independently by two reviewers. Full-text review and data extraction were completed by four trained clinician coders with regular validation for consistency. We extracted the definition of POMR used, clinical risk scores reported, and strategies for risk adjustment in addition to reported mortality rates. FINDINGS: We screened 2657 abstracts and included 373 full-text articles. 493 409 patients in 68 countries and 12 surgical specialties were represented. The most common definition for the numerator of POMR was in-hospital deaths following surgery (55·3%) and for the denominator it was the number of operative patients (96·2%). Few studies reported preoperative comorbidities (41·8%), ASA status (11·3%), and HIV status (7·8%), with a smaller proportion stratifying on or adjusting mortality for these factors. Studies reporting on planned procedures recorded a median mortality of 1·2% (n=121 [IQR 0·0-4·7]). Median mortality was 10·1% (n=182 [IQR 2·5-16·2) for emergent procedures. INTERPRETATION: POMR is frequently reported in LMICs, but a standardised approach for reporting and risk stratification is absent from the literature. There was wide variation in POMR across procedures and specialties. A quality assessment checklist for surgical mortality studies could improve mortality reporting and facilitate benchmarking across sites and countries. FUNDING: None.

Geospatial mapping to estimate timely access to surgical care in nine low-income and middle-income countries.

BACKGROUND: The Lancet Commission on Global Surgery calls for universal access to safe, affordable, and timely surgical care. Two requisite components of timely access are (1) the ability to reach a surgical provider in a given timeframe, and (2) the ability to receive appropriately prompt care from that provider. We chose a threshold of 2 h in view of its relevance in time-to-death in post-partum haemorrhage. Here, we use geospatial mapping to enumerate the percentage of a nation's population living within 2 h of a surgeon and the surgeon-to-population ratio for each provider. METHODS: Geospatial mapping was used to identify the population living within a 2-h driving distance (access zone) of a health-care facility staffed by a surgeon. Surgeon locations were extracted from Ministries of Health, professional society databases, and published literature for countries which had available data. Data were reviewed by individuals knowledgeable of in-country distribution. Spatial distribution of providers was mapped with Google Maps engine. Access zones were constructed around every provider through estimation of driving times in Google Maps. The number of people living within zones was estimated with the Socioeconomic Data and Applications Center Population Estimation Service. Surgeon-to-population ratios were constructed for every individual access zone and averaged to report a single ratio. FINDINGS: Results (% country's population living within an access zone; average surgeon:population ratio within all access zones) are reported for nine countries with available data: Somaliland (16·9%; 1:118 306), Botswana (31·0%; 1:64 635), Ethiopia (39·6%; 1:229 696), Rwanda (41·3%; 1:158 484), Namibia (43·4%; 1:69 385), Zimbabwe (54%; 1:148 292), Mongolia (55·5%; 1:10 500), Sierra Leone (70·3%; 1:106 742), and Pakistan (84·4%, 1:139 299). Surgeon-to-population ratios vary substantially even within countries; in Sierra Leone, urban access zones have a ratio of 1:45 058 and rural access zones have a ratio of 1:467 929. INTERPRETATION: Surgical access is poor in many low-income and middle-income countries, even when using a narrow definition of surgical access consisting only of timeliness. Living outside of an access zone makes timely access to surgical care highly unlikely, and in view of low surgeon-to-population ratios and poor prehospital transport, even living within a 2-h access zone might not confer 2-h access. Investments in infrastructure and training must be prioritised to address widespread disparity in access to timely surgery. FUNDING: None.

A time-driven activity-based costing model to improve health-care resource use in Mirebalais, Haiti.

BACKGROUND: In resource-limited settings, efficiency is crucial to maximise resources available for patient care. Time driven activity-based costing (TDABC) estimates costs directly from clinical and administrative processes used in patient care, thereby providing valuable information for process improvements. TDABC is more accurate and simpler than traditional activity-based costing because it assigns resource costs to patients based on the amount of time clinical and staff resources are used in patient encounters. Other costing approaches use somewhat arbitrary allocations that provide little transparency into the actual clinical processes used to treat medical conditions. TDABC has been successfully applied in European and US health-care settings to facilitate process improvements and new reimbursement approaches, but it has not been used in resource-limited settings. We aimed to optimise TDABC for use in a resource-limited setting to provide accurate procedure and service costs, reliably predict financing needs, inform quality improvement initiatives, and maximise efficiency. METHODS: A multidisciplinary team used TDABC to map clinical processes for obstetric care (vaginal and caesarean deliveries, from triage to post-partum discharge) and breast cancer care (diagnosis, chemotherapy, surgery, and support services, such as pharmacy, radiology, laboratory, and counselling) at Hôpital Universitaire de Mirebalais (HUM) in Haiti. The team estimated the direct costs of personnel, equipment, and facilities used in patient care based on the amount of time each of these resources was used. We calculated inpatient personnel costs by allocating provider costs per staffed bed, and assigned indirect costs (administration, facility maintenance and operations, education, procurement and warehouse, bloodbank, and morgue) to various subgroups of the patient population. This study was approved by the Partners in Health/Zanmi Lasante Research Committee. FINDINGS: The direct cost of an uncomplicated vaginal delivery at HUM was US$62 and the direct cost of a caesarean delivery was US$249. The direct costs of breast cancer care (including diagnostics, chemotherapy, and mastectomy) totalled US$1393. A mastectomy, including post-anaesthesia recovery and inpatient stay, totalled US$282 in direct costs. Indirect costs comprised 26-38% of total costs, and salaries were the largest percentage of total costs (51-72%). INTERPRETATION: Accurate costing of health services is vital for financial officers and funders. TDABC showed opportunities at HUM to optimise use of resources and reduce costs-for instance, by streamlining sterilisation procedures and redistributing certain tasks to improve teamwork. TDABC has also improved budget forecasting and informed financing decisions. HUM leadership recognised its value to improve health-care delivery and expand access in low-resource settings.

Monitoring and evaluating surgical care: defining perioperative mortality rate and standardising data collection.

BACKGROUND: Case volume per 100 000 population and perioperative mortality rate (POMR) are key indicators to monitor and strengthen surgical services. However, comparisons of POMR have been restricted by absence of standardised approaches to when it is measured, the ideal denominator, need for risk adjustment, and whether data are available. We aimed to address these issues and recommend a minimum dataset by analysing four large mixed surgical datasets, two from well-resourced settings with sophisticated electronic patient information systems and two from resource-limited settings where clinicians maintain locally developed databases. METHODS: We obtained data from the New Zealand (NZ) National Minimum Dataset, the Geelong Hospital patient management system in Australia, and purpose-built surgical databases in Pietermaritzburg, South Africa (PMZ) and Port Moresby, Papua New Guinea (PNG). Information was sought on inclusion and exclusion criteria, coding criteria, and completeness of patient identifiers, admission, procedure, discharge and death dates, operation details, urgency of admission, and American Society of Anesthesiologists (ASA) score. Date-related errors were defined as missing dates and impossible discrepancies. For every site, we then calculated the POMR, the effect of admission episodes or procedures as denominator, and the difference between in-hospital POMR and 30-day POMR. To determine the need for risk adjustment, we used univariate and multivariate logistic regression to assess the effect on relative POMR for each site of age, admission urgency, ASA score, and procedure type. FINDINGS: 1 365 773 patient admissions involving 1 514 242 procedures were included, among which 8655 deaths were recorded within 30 days. Database inclusion and exclusion criteria differed substantially. NZ and Geelong records had less than 0·1% date-related errors and greater than 99·9% completeness. PMZ databases had 99·9% or greater completeness of all data except date-related items (94·0%). PNG had 99·9% or greater completeness for date of birth or age and admission date and operative procedure, but 80-83% completeness of patient identifiers and date related items. Coding of procedures was not standardised, and only NZ recorded ASA status and complete post-discharge mortality. In-hospital POMR range was 0·38% in NZ to 3·44% in PMZ, and in NZ it underestimated 30-day POMR by roughly a third. The difference in POMR by procedures instead of admission episodes as denominator ranged from 10% to 70%. Age older than 65 years and emergency admission had large independent effects on POMR, but relatively little effect in multivariate analysis on the relative odds of in-hospital death at each site. INTERPRETATION: Hospitals can collect and provide data for case volume and POMR without sophisticated electronic information systems. POMR should initially be defined by in-hospital mortality because post-discharge deaths are not usually recorded, and with procedures as denominator because details allowing linkage of several operations within one patient's admission are not always present. Although age and admission urgency are independently associated with POMR, and ASA and case mix were not included, risk adjustment might not be essential because the relative odds between sites persisted. Standardisation of inclusion criteria and definitions is needed, as is attention to accuracy and completeness of dates of procedures, discharge and death. A one-page, paper-based form, or alternatively a simple electronic data collection form, containing a minimum dataset commenced in the operating theatre could facilitate this process. FUNDING: None.

Bellwether Procedures for Monitoring and Planning Essential Surgical Care in Low- and Middle-Income Countries: Caesarean Delivery, Laparotomy, and Treatment of Open Fractures.

BACKGROUND: Surgical conditions represent a significant proportion of the global burden of disease, and therefore, surgery is an essential component of health systems. Achieving universal health coverage requires effective monitoring of access to surgery. However, there is no widely accepted standard for the required capabilities of a first-level hospital. We aimed to determine whether a group of operations could be used to describe the delivery of essential surgical care. METHODS: We convened an expert panel to identify procedures that might indicate the presence of resources needed to treat an appropriate range of surgical conditions at first-level hospitals. Using data from the World Health Organization Emergency and Essential Surgical Care Global database, collected using the WHO Situational Analysis Tool (SAT), we analysed whether the ability to perform each of these procedures-which we term "bellwether procedures"-was associated with performing a full range of essential surgical procedures. FINDINGS: The ability to perform caesarean delivery, laparotomy, and treatment of open fracture was closely associated with performing all obstetric, general, basic, emergency, and orthopaedic procedures (p < 0.001) in the population that responded to the WHO SAT Survey. Procedures including cleft lip, cataract, and neonatal surgery did not correlate with performing the bellwether procedures. INTERPRETATION: Caesarean delivery, laparotomy, and treatment of open fractures should be standard procedures performed at first-level hospitals. With further validation in other populations, local managers and health ministries may find this useful as a benchmark for what first-level hospitals can and should be able to perform on a 24/7 basis in order to ensure delivery of emergency and essential surgical care to their population. Those procedures which did not correlate with the bellwether procedures can be referred to a specialized centre or collected for treatment by a visiting specialist team.

Long-term Outcomes Following Thoracoscopic Division of Vascular Rings.

OBJECTIVES: We evaluate long-term symptomatic improvement in vascular ring patients who underwent thoracoscopic division at a single quaternary pediatric surgery center. METHODS: All pediatric patients who underwent vascular ring division without Kommerell's diverticulum resection between 01/2007-12/2022 were included. Surgeries were performed by pediatric general and thoracic surgeons. Patient demographic and clinical characteristics were obtained from retrospective chart review. Data on long-term symptomatic improvement were collected with structured telephone interviews. RESULTS: 60% of patients were male. Median age at operation was 24 months (IQR: 11, 60 months) with a median weight of 11.3 kg (IQR: 8.7, 19.8 kg). All patients were symptomatic preoperatively with dysphagia being the most frequent complaint (42%), followed by chronic cough (21%). Of 41 patients eligible for the long-term follow-up survey, 8 patients with a primary diagnosis of a double arch with an atretic segment in the non-dominant arch and 9 with a right dominant arch with left ligamentum arteriosum and aberrant left subclavian artery (LSCA) were contacted and consented for participation. Median interval from surgery to survey completion was 95 months (IQR 28, 135 months). Most patients had no, or only minor, symptoms related to breathing and swallowing at the time of long-term follow-up. 88% of patients experienced postoperative symptom improvement, and only one patient reported worsening of symptoms over time. CONCLUSION: Division of an atretic arch and/or ligamentum for patients with an aberrant LSCA without Kommerell's resection may be adequate to ensure long-term improvement of breathing and swallowing problems attributable to vascular rings.

General Care Considerations for the Pediatric Trauma Patient.

Trauma is a leading cause of morbidity and mortality for children in the United States. Access to trauma care, injury burden, and outcomes following injury, are inequitable. There are many anatomic and physiologic differences between children and adults that affect injury patterns and necessary trauma treatment. The principles of advanced trauma life support (ATLS) should be used by clinicians in high-resource settings for the immediate in-hospital treatment of the injured child.

The intersection of pediatric surgery, climate change, and equity.

Climate change is occurring at an unprecedented rate. Recent years have seen heatwaves, wildfires, floods, droughts, and re-emerging infectious diseases fueled by global warming. Global warming has also increased the frequency and severity of surgical disease, particularly for children, who bear an estimated 88% of the global burden of disease attributable to climate change. Health care delivery itself weighs heavily on the environment, accounting for nearly 5% of global greenhouse gas emissions. Within the health care sector, surgery and anesthesia are particularly carbon intensive. The surgical community must prioritize the intersection of climate change and pediatric surgery in order to address pediatric surgical disease on a global scale, while reducing the climate impact of surgical care delivery. This review defines the current state of climate change and its effects on pediatric surgical disease, discusses climate justice, and outlines actions to reduce the climate impact of surgical services.

Understanding Hispanic Patient Satisfaction with Telehealth During COVID-19.

BACKGROUND: Recent studies have described the use of telehealth for pediatric surgical care during the COVID-19 pandemic. We aimed to evaluate equity in telehealth use by comparing rates of utilization and satisfaction with pediatric surgical telemedicine among Hispanic patients. METHODS: We conducted a retrospective cohort study of patients seen by a surgical subspecialty provider in the outpatient setting at a quaternary pediatric hospital between April 1 and June 30, 2020. Patients evaluated in the same three-month period in 2019 were analyzed as a historic control. Differences in Family Experience Survey (FES) responses based on race and ethnicity and preferred language of care were assessed using univariable and multivariable generalized linear modeling. RESULTS: The pandemic cohort included fewer patients of Hispanic ethnicity and fewer Spanish-speakers. After controlling for visit type, comparison of Spanish-speaking and English-speaking patients revealed that Spanish-speaking families had significantly lower scores for FES items that evaluated healthcare provider explaining (IRR 0.74, 95% CI: 0.61-0.90), listening (IRR 0.76, 95% CI: 0.63-0.92), and time spent with the family (IRR 0.73, 95% CI: 0.60-0.89). There were no differences in FES responses based on insurance status or degree of medical complexity. CONCLUSIONS: Telehealth services were less commonly used among Hispanic and Spanish-speaking patients. Language may differentially affect family satisfaction with healthcare and telehealth solutions. Strategies to mitigate these inequities are needed and may include strengthening interpreter services and providing language-concordant care. LEVEL OF EVIDENCE: Level IV.

Environmental impact of telehealth use for pediatric surgery.

BACKGROUND: The healthcare sector is responsible for 10% of US greenhouse gas emissions. Telehealth use may decrease healthcare's carbon footprint. Our institution introduced telehealth to support SARS-CoV-2 social distancing. We aimed to evaluate the environmental impact of telehealth rollout. METHODS: We conducted a retrospective cohort study of pediatric patients seen by a surgical or pre anesthesia provider between March 1, 2020 and March 1, 2021. We measured patient-miles saved and CO2 emissions prevented to quantify the environmental impact of telehealth. Miles saved were calculated by geodesic distance between patient home address and our institution. Emissions prevented were calculated assuming 25 miles per gallon fuel efficiency and 19.4 pounds of CO2 produced per gallon of gasoline consumed. Unadjusted Poisson regression was used to assess relationships between patient demographics, geography, and telehealth use. RESULTS: 60,773 in-person and 10,626 telehealth encounters were included. This represented an 8,755% increase in telehealth use compared to the year prior. Telehealth resulted in 887,006 patient-miles saved and 688,317 fewer pounds of CO2 emitted. Demographics significantly associated with decreased telehealth use included Asian and Black/African American racial identity, Hispanic ethnic identity, and primary language other than English. Further distance from the hospital and higher area deprivation index were associated with increased telehealth use (IRR 1.0006 and 1.0077, respectively). CONCLUSION: Incorporating telehealth into pediatric surgical and pre anesthesia clinics resulted in significant CO2 emission reductions. Expanded telehealth use could mitigate surgical and anesthesia service contributions to climate change. Racial and linguistic minority status were associated with significantly lower rates of telehealth utilization, necessitating additional inquiry into equitable telemedicine use for minoritized populations.

Magnetic resonance imaging of children following esophageal button battery removal: What are we looking for?

Despite society recommendations that cross-sectional imaging be obtained following removal of ingested button batteries, there is no published consensus on how it effectively guides clinical management. This single institution survey demonstrates a lack of uniformity by clinicians regarding which imaging findings impact management decisions, highlighting the need for further guidelines.

COVID-19-associated multisystem inflammatory syndrome in children (MIS-C) presenting as appendicitis with shock.

Multisystem inflammatory syndrome in children (MIS-C) is an identified complication of the COVID-19 infection. A common presentation of both COVID-19 and MIS-C is acute abdominal pain, sometimes mimicking appendicitis. We report two cases of patients initially diagnosed with appendicitis who either presented with or developed signs of shock and were found to have MIS-C. An 8-year-old girl who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase-polymerase chain reaction (RT-PCR) presented with fever, abdominal pain, and shock with ultrasound findings consistent with acute appendicitis. After being treated for MIS-C, she underwent appendectomy and improved. Final pathology was consistent with acute appendicitis. A 9-year-old girl who tested negative for COVID RT-PCR presented with uncomplicated appendicitis and underwent laparoscopic appendectomy, but developed post-operative fever and shock. Antibody testing was positive and she responded to treatment for MIS-C. Histology showed lymphohistiocytic inflammation within the muscularis propria, mesoappendix and serosa without the typical neutrophil-rich inflammation and mucosal involvement of acute appendicitis. The diagnosis was MIS-C, not appendicitis. Given the new reality of the COVID-19 pandemic, pediatric surgeons must be aware of MIS-C as a possible diagnosis and should understand the diagnostic criteria and current treatment guidelines.
