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.

Better together: a reappraisal of heterotopic heart transplantation.

Heterotopic heart transplantation (HHT) is rare in the modern era. When used as a biologic left ventricular assist, HHT provides pulsatile flow, supports the left ventricle with a physiologic cardiac output, responds to humoral stimuli, and with modern immunosuppression may offer long-term untethered survival. This study was undertaken to compare survival of HHT with orthotopic heart transplantation (OHT) to assess its viability in the modern era. In the United Network for Organ Sharing database, from January 1999 to December 2020, there were 27691 bicaval OHT, 13836 biatrial OHT, 1271 total OHT, and 51 HHT with sufficient follow-up. Survival was analyzed using restricted mean survival time (RMST) through 4 years as the outcome. In the first 4 years after transplant, compared with HHT, differences in RMST were 0.1 years (99% CI: -0.4 to 0.5 years) for bicaval OHT, 0.0 years (99% CI: -0.4 to 0.5 years) for biatrial OHT, and 0.0 years (99% CI: -0.5 to 0.4 years) for total OHT. In this cohort, survival was indistinguishable between HHT and OHT recipients in the first four years. Thus, HHT might be a viable alternative to durable mechanical circulatory assist particularly with size mismatched grafts or for patients with refractory pulmonary hypertension.

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.

Health Disparities Research: What Every Pediatric Surgeon Should Know.

While the earliest published health disparity research in the United States dates to 1899, the field was not formally established until the late 20th century. Initially focused on race and ethnicity, the field has broadened to include socioeconomic status. Several measures have been developed to quantify socioeconomic disadvantage, including the Social Vulnerability Index, Area Deprivation Index, and Child Opportunity Index. These indices have been validated and demonstrate correlation with health outcomes. However, socioeconomic status cannot fully explain health inequities experienced by people of minoritized racial and ethnic identities. Three generations of health disparities research have been described-identification of disparities, root analysis, and development of interventions to mitigate health inequities. While there has been an increase in publication of health disparity research, there is little third generation work. It is imperative that health disparities research move beyond defining the problem and toward interventions that will reduce health inequities. LEVELS OF EVIDENCE: Level IV.

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.

Implementation of a Cryoablation-based Pain Management Protocol for Pectus Excavatum.

INTRODUCTION: The Nuss repair for pectus excavatum is associated with significant postoperative pain. Our institution developed protocols to standardize pain management for pectus excavatum patients in the immediate postoperative period. We present our experience with protocol implementation and patient outcomes. METHODS: We standardized regional anesthesia with a 0.25% bupivacaine incisional soaker catheter (post-implementation 1, PI1) before transitioning to intercostal nerve cryoablation (INC) (post-implementation 2, PI2). Patient outcomes were tracked using statistical process control charts in AdaptX™ OR Advisor and run charts in Tableau. Chi-squared tests assessed demographic differences between cohorts. RESULTS: 244 patients were included: 78 pre-implementation, 108 PI1, and 58 PI2. Average age was 15.9-16.5 years. Patients were majority male, non-Hispanic white, and English speaking. Hospital length of stay decreased 4.1-2.4 days. INC increased surgery time (99-125 min) but decreased PACU time (112-78 min). Maximum pain scores improved in PACU (7.7-6.0) and 0-24 h postoperatively (8.3-6.8) but were not different 24-48 h postoperatively (5.4-5.8). Average opioid dosing decreased 0-48 h from 1.9 to 0.8 mg/kg morphine milliequivalents and was associated with reduction in post-operative nausea and constipation. There were no 30-day readmissions. CONCLUSION: An institution-wide pain management protocol using INC for pectus excavatum patients was implemented. Intercostal nerve cryoablation was found to be superior to bupivacaine incisional soaker catheters and reduced hospital length of stay, immediate postoperative pain scores, morphine milliequivalent opioid dosing, postoperative nausea, and constipation.

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.

Debunking Myths of Gender Informed Care: What Every Pediatric Surgeon Should Know.

As the transgender population in the United States grows, gender-affirming care is becoming increasingly relevant to the practice of pediatric surgery. Medical care for the transgender and gender diverse population is a politically charged topic with significant complexity and opportunities for clarification. It is important for providers to better understand this population's unique health and social needs. This review aims to debunk long-standing myths regarding gender-affirming care and highlight the current therapeutic and legislative landscapes within the scope of pediatric surgical practice.

Population Density and Triage of Pediatric Firearm Injuries in a Rural Trauma System.

BACKGROUND: Rural pediatric firearm injuries require regional pediatric and trauma expertise. We evaluated county-level population density associations with transport, hospital interventions, and patient outcomes at a Level I pediatric trauma center serving a rural, statewide catchment area. MATERIAL AND METHODS: The trauma registry of the only in-state pediatric trauma center was reviewed for firearm injuries in patients < 18 between 1/2013 and 3/2020. County-level population density was classified according to the United States Office of Management and Budget definitions for rural, micropolitan, and metropolitan areas. RESULTS: 364 patients were identified, including 7 patients who were re-injured. Mean age was 11.3 ± 4.5 y and patients were 79.4% male. 59.3% were transferred from a referring hospital. Median injury severity score was 5 (IQR 1-10); 88.0% required trauma center admission, and 48.2% required operative intervention. 7.4% were injured in a rural county, 46.4% in a micropolitan county, and 46.2% in a metropolitan county. Patients from rural counties were more likely to be unintentionally injured (72.0%) than those from micropolitan (54.4%) or metropolitan counties (44.0%, P = .04). While need for inpatient admission and length of stay were similar, those transported from rural counties had significantly longer transport times (P < .01) and less frequent need for operative intervention (P = .03), as well as trends toward lower injury severity (P = .08) and mortality (P = .06). CONCLUSION: Management of pediatric firearm injury is a unique challenge with significant regional variability. Opportunities exist for outreach, telehealth, and decision support to ensure equitable distribution of resources in rural trauma systems. LEVEL OF EVIDENCE: Epidemiological, Level III.

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.

Sevelamer crystals-an unusual cause of large bowel obstruction.

Sevelamer is a common phosphate binder used to manage hyperphosphatemia in end-stage renal disease. The medication has a well-documented gastrointestinal side-effect profile including nausea, vomiting and abdominal pain. There are few case reports of Sevelamer crystal deposition causing gastrointestinal mucosal injury, pseudotumor or obstruction. Here, we discuss a patient on Sevelamer who required operative management of a sigmoid obstruction. Surgical pathology showed pericolonic abscess with Sevelamer crystals.

Utilization of a handheld telemedicine device in postoperative pediatric surgical care.

PURPOSE: The purpose of this study was to assess the utilization of a handheld telemedicine (TM) device in the postoperative care of pediatric surgical patients. METHODS: We performed postoperative TM evaluations using an advanced medical tablet immediately prior to seeing the patients in clinic as well as at two different time points from their home. The caregivers and physicians were surveyed about their overall satisfaction. RESULTS: Twenty-four postoperative patients who underwent a variety of general surgical operations were included. There were no changes to the TM plan of care following "in person" evaluations (n = 12) and no complications, missed diagnoses, emergency department visits, or additional clinic visits in those who only had TM postoperative evaluations (n = 12). Caregiver satisfaction ratings were 3.92 ±â€¯0.28 out of 4 (4 = very satisfied). Ninety-two percent of caregivers responded that they would be comfortable with a TM-only postoperative evaluation in the future. The physician was able to formulate an accurate assessment and plan using the device. The average travel distance saved was 44.7 ±â€¯45.5 miles (range = 10-150 miles). CONCLUSIONS: These preliminary data suggest safe and effective care with high caregiver and physician satisfaction can be provided by utilizing TM in the postoperative care of pediatric surgical patients.

Nationwide implementation of integrated community case management of childhood illness in Rwanda.

BACKGROUND: Between 2008 and 2011, Rwanda introduced integrated community case management (iCCM) of childhood illness nationwide. Community health workers in each of Rwanda's nearly 15,000 villages were trained in iCCM and equipped for empirical diagnosis and treatment of pneumonia, diarrhea, and malaria; for malnutrition surveillance; and for comprehensive reporting and referral services. METHODS: We used data from the Rwanda health management information system (HMIS) to calculate monthly all-cause under-5 mortality rates, health facility use rates, and community-based treatment rates for childhood illness in each district. We then compared a 3-month baseline period prior to iCCM implementation with a seasonally matched comparison period 1 year after iCCM implementation. Finally, we compared the actual changes in all-cause child mortality and health facility use over this time period with the changes that would have been expected based on baseline trends in Rwanda. RESULTS: The number of children receiving community-based treatment for diarrhea and pneumonia increased significantly in the 1-year period after iCCM implementation, from 0.83 cases/1,000 child-months to 3.80 cases/1,000 child-months (P = .01) and 0.25 cases/1,000 child-months to 5.28 cases/1,000 child-months (P<.001), respectively. On average, total under-5 mortality rates declined significantly by 38% (P<.001), and health facility use declined significantly by 15% (P = .006). These decreases were significantly greater than would have been expected based on baseline trends. CONCLUSIONS: This is the first study to demonstrate decreases in both child mortality and health facility use after implementing iCCM of childhood illness at a national level. While our study design does not allow for direct attribution of these changes to implementation of iCCM, these results are in line with those of prior studies conducted at the sub-national level in other low-income countries.

Prediction of severe disease in children with diarrhea in a resource-limited setting.

OBJECTIVE: To investigate the accuracy of three clinical scales for predicting severe disease (severe dehydration or death) in children with diarrhea in a resource-limited setting. METHODS: Participants included 178 children admitted to three Rwandan hospitals with diarrhea. A local physician or nurse assessed each child on arrival using the World Health Organization (WHO) severe dehydration scale and the Centers for Disease Control (CDC) scale. Children were weighed on arrival and daily until they achieved a stable weight, with a 10% increase between admission weight and stable weight considered severe dehydration. The Clinical Dehydration Scale was then constructed post-hoc using the data collected for the other two scales. Receiver Operator Characteristic (ROC) curves were constructed for each scale compared to the composite outcome of severe dehydration or death. RESULTS: The WHO severe dehydration scale, CDC scale, and Clinical Dehydration Scale had areas under the ROC curves (AUCs) of 0.72 (95% CI 0.60, 0.85), 0.73 (95% CI 0.62, 0.84), and 0.80 (95% CI 0.71, 0.89), respectively, in the full cohort. Only the Clinical Dehydration Scale was a significant predictor of severe disease when used in infants, with an AUC of 0.77 (95% CI 0.61, 0.93), and when used by nurses, with an AUC of 0.78 (95% CI 0.63, 0.93). CONCLUSIONS: While all three scales were moderate predictors of severe disease in children with diarrhea, scale accuracy varied based on provider training and age of the child. Future research should focus on developing or validating clinical tools that can be used accurately by nurses and other less-skilled providers to assess all children with diarrhea in resource-limited settings.
