Investments in surgical systems contribute to pandemic readiness and health system resilience

Safe surgical care, including anesthesia, obstetrics, and trauma, is an essential component of a functional health system, yet five billion people lack access to high-quality, timely and affordable surgical care. As health decision makers are grappling with how to make appropriate investments for crisis readiness and resilience, investments in surgical care should be considered for their compounding benefits to meet a country’s diverse health goals. National Surgical, Obstetric, and Anesthesia Plans (NSOAPs) are developed through global partnerships and multi-stakeholder consensus and provide a dynamic framework for surgical scale-up that also improves the resilience of the larger health system. Our paper applies principles from the literature on health system resilience to surgical systems and examines the unique capabilities of the surgical workforce and infrastructure to be redeployed during times of crisis, using examples from the current pandemic

Understanding the Operative Experience of the Practicing Pediatric Surgeon: Implications for Training and Maintaining Competency

Importance The number of practicing pediatric surgeons has increased rapidly in the past 4 decades, without a significant increase in the incidence of rare diseases specific to the field. Maintenance of competency in the index procedures for these rare diseases is essential to the future of the profession. Objective To describe the demographic characteristics and operative experiences of practicing pediatric surgeons using Pediatric Surgery Board recertification case log data. Design, Setting, and Participants We performed a retrospective review of 5 years of pediatric surgery certification renewal applications submitted to the Pediatric Surgery Board between 2009 and 2013. A surgeon’s location was defined by population as urban, large rural, small rural, or isolated. Case log data were examined to determine case volume by category and type of procedures. Surgeons were categorized according to recertification at 10, 20, or 30 years. Main Outcome and Measure Number of index cases during the preceding year. Results Of 308 recertifying pediatric surgeons, 249 (80.8%) were men, and 143 (46.4%) were 46 to 55 years of age. Most of the pediatric surgeons (304 of 308 [98.7%]) practiced in urban areas (ie, with a population >50 000 people). All recertifying applicants were clinically active. An appendectomy was the most commonly performed procedure (with a mean [SD] number of 49.3 [35.0] procedures per year), nonoperative trauma management came in second (with 20.0 [33.0] procedures per year), and inguinal hernia repair for children younger than 6 months of age came in third (with 14.7 [13.8] procedures per year). In 6 of 10 “rare” pediatric surgery cases, the mean number of procedures was less than 2. Of 308 surgeons, 193 (62.7%) had performed a neuroblastoma resection, 170 (55.2%) a kidney tumor resection, and 123 (39.9%) an operation to treat biliary atresia or choledochal cyst in the preceding year. Laparoscopy was more frequently performed in the 10-year recertification group for Nissen fundoplication, appendectomy, splenectomy, gastrostomy/jejunostomy, orchidopexy, and cholecystectomy (P < .05) but not lung resection (P = .70). It was more frequently used by surgeons recertifying in the 10-year group (used in 11 375 of 14 456 procedures [78.7%]) than by surgeons recertifying in the 20-year (used in 6214 of 8712 procedures [71.3%]) or 30-year group (used in 2022 of 3805 procedures [53.1%]). Conclusions and Relevance Practicing pediatric surgeons receive limited exposure to index cases after training. With regard to maintaining competency in an era in which health care outcomes have become increasingly important, these results are concerning

Validation of the World Health Organization Tool for Situational Analysis to Assess Emergency and Essential Surgical Care at District Hospitals in Ghana

The World Health Organization (WHO) Tool for Situational Analysis to Assess Emergency and Essential Surgical Care (hereafter called the WHO Tool) has been used in more than 25 countries and is the largest effort to assess surgical care in the world. However, it has not yet been independently validated. Test–retest reliability is one way to validate the degree to which tests instruments are free from random error. The aim of the present field study was to determine the test–retest reliability of the WHO Tool. The WHO Tool was mailed to 10 district hospitals in Ghana. Written instructions were provided along with a letter from the Ghana Health Services requesting the hospital administrator to complete the survey tool. After ensuring delivery and completion of the forms, the study team readministered the WHO Tool at the time of an on-site visit less than 1 month later. The results of the two tests were compared to calculate kappa statistics for each of the 152 questions in the WHO Tool. The kappa statistic is a statistical measure of the degree of agreement above what would be expected based on chance alone. Ten hospitals were surveyed twice over a short interval (i.e., less than 1 month). Weighted and unweighted kappa statistics were calculated for 152 questions. The median unweighted kappa for the entire survey was 0.43 (interquartile range 0–0.84). The infrastructure section (24 questions) had a median kappa of 0.81; the human resources section (13 questions) had a median kappa of 0.77; the surgical procedures section (67 questions) had a median kappa of 0.00; and the emergency surgical equipment section (48 questions) had a median kappa of 0.81. Hospital capacity survey questions related to infrastructure characteristics had high reliability. However, questions related to process of care had poor reliability and may benefit from supplemental data gathered by direct observation. Limitations to the study include the small sample size: 10 district hospitals in a single country. Consistent and high correlations calculated from the field testing within the present analysis suggest that the WHO Tool for Situational Analysis is a reliable tool where it measures structure and setting, but it should be revised for measuring process of care

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

mob-1, a novel mediator of ARDS

Adult respiratory distress syndrome (ARDS) is a pulmonary inflammatory process triggered by a variety of stress conditions some remote from the lung, which leads to microvascular injury with subsequent respiratory failure and death. The present work aimed to implicate mob-1, a recently cloned member of the $\alpha$ chemokine family, in the pathogenesis of this grave syndrome using a rat model of ARDS-like lung injury produced by IL-2. To that end, differential display was utilized to identify pulmonary mob-1 and time course as well as cellular localization of mob-1 mRNA were established. Furthermore, to delineate mob-1 function, the protein was recombinantly produced using a bacterial expression system and tested for in vivo, in vitro, and ex vivo effects. Differential display of lungs harvested from IL-2-treated rats identified a highly-inducible band ($\sim$250 bp), termed B1, which presented 99.14% homology to the previously cloned mob-1. Pulmonary mob-1 mRNA was upregulated prior (1 hr) to the onset of lung injury (4 hrs), localized to pulmonary alveolar macrophages by in situ hybridization, and suppressed by TNF$\alpha$ inhibition (neutralizing anti-TNF$\alpha$ mAb or rolipram). Recombinant mob-1 was successfully expressed as a histidine-tagged fusion protein in E. coli and purified using nickel chromatography with subsequent enterokinase digestion. The purified recombinant protein was then subjected to SDS-PAGE and sized to $\sim$8kD by silver stain and Western Blot analysis. In vivo, intratracheal injection of mob-1 (50 $\mu$g/rat) induced leukocyte accumulation in lung tissue (MPO +93 $\pm$ 8% vs. control, p $\u3c$ 0.05) with preferential accumulation of neutrophils in bronchoalveolar lavage fluid (36.0 $\pm$ 1.0% vs. 0.1 $\pm$ 0.1% in controls, p $\u3c$ 0.01). In contrast, mob-1 had no effect on pulmonary edema and bronchoalveolar lavage fluid protein concentration. In vitro, transwell migration studies demonstrated chemotactic activity of mob-1 towards human monocytes (+151 $\pm$ 34% vs. mob-1 vehicle, p $\u3c$ 0.01) and only weak chemotaxis for human neutrophils (+15 $\pm$ 0% vs. mob-1 vehicle, p $\u3c$ 0.01). In concert, these data suggest that mob-1 promotes lung injury by chemoattraction of leukocytes through an indirect effect. Since angiogenesis is a major component of the resolution process of ARDS and because IP-10, the human homologue of mob-1, is known to exert angiostatic properties, the ability of mob-1 to affect angiogenesis was tested in a rat aortic ring model ex vivo. Indeed, mob-1 (100 ng/ml) exerted a very potent inhibitory effect on bFGF-induced angiogenesis (21.3 $\pm$ 6.3%, p $\u3c$ 0.01). Taken together, these data support the involvement of mob-1 in the development of ARDS, conceivably through chemotactic actions on inflammatory cells and modulation of angiogenesis in the recovery phase of the syndrome. The clinical relevance of these findings awaits further investigation
