Treatment Facility Case Volume and Disparities in Outcomes of Congenital Diaphragmatic Hernia Cases.

INTRODUCTION: Congenital diaphragmatic hernia (CDH) is a life-threatening, prenatally diagnosed congenital anomaly. We aim to characterize care and outcomes of infants with CDH in Texas and the impact of treating facilities volume of care. METHODS: Retrospective cohort study using a state-wide Hospital Inpatient Discharge Public Use Data File was conducted (2013-2021). Neonates and infants <1 year of age were included using CDH ICD-9/ICD-10 codes. Neonates transferred to an outside hospital were excluded to avoid double-counting. Descriptive statistics, chi-square and logistic regression analysis were performed. RESULTS: Of 1314 CDH patient encounters identified, 728 (55%) occurred at 5 higher volume centers (HVC, >75 cases), 326 (25%) at 9 mid-volume centers (MVC, 20-75 cases) and 268 (20%) at 79 low volume centers (LVC, <20 cases). HVC had lower mortality rates (18%, MVC 22% vs LVC 27%; p = 0.011) despite treating sicker patients (extreme illness severity: HVC 71%, MVC 62% vs LVC 50%; p < 0.001) with longer length-of-stay (p < 0.001). Extracorporeal membrane oxygenation was used in 136 (10%) and provided primarily at HVC. LVC treated proportionately more non-white Hispanic patients (p < 0.001) and patients from counties along the Mexican border (p < 0.001). The predicted probability of mortality in CDH patients decreases with higher treatment facility CDH case volume, with a 0.5% decrease in the odds of mortality for every additional CDH case treated (p < 0.001). CONCLUSIONS: Patients treated in HVC have significantly lower mortality despite increased severity. Our data suggest minority populations may be disproportionately treated at LVC associated with worse outcomes. TYPE OF STUDY: Retrospective Prognosis Study. LEVEL OF EVIDENCE: Level II.

Surfactant Therapy in Congenital Diaphragmatic Hernia and Fetoscopic Endoluminal Tracheal Occlusion.

INTRODUCTION: Congenital diaphragmatic hernia (CDH) is a complex pathology with severe pulmonary morbidity. Administration of surfactant in CDH is controversial, and the advent of fetoscopic endoluminal tracheal occlusion (FETO) has added further complexity. While FETO has been shown to improve survival outcomes, there are risks of prematurity and potential surfactant deficiency. We aim to evaluate the characteristics and outcomes of surfactant administration for CDH infants and elucidate potential benefits or risks in this unique population. METHODS: A single-center retrospective cohort review of patients with unilateral CDH from September 2015 to July 2022 was performed. Demographics, prognostic perinatal imaging features, and outcomes were collected. Patients were stratified by surfactant administration and history of FETO. Data were analyzed with descriptive statistics, two-sample t-tests, chi-squared analyses, and logistic regression. RESULTS: Of 105 included patients, 19 (18%) underwent FETO and 25 (24%) received surfactant. Overall, surfactant recipients were born at earlier gestational ages and lower birthweights regardless of FETO history. Surfactant recipients possessed significantly worse prenatal prognostic features such as observed to expected total fetal lung volume, observed to expected lung to head ratio, and percent liver herniation. In CDH patients without FETO history, surfactant recipients demonstrated worse outcomes than nonrecipients. This association is notably absent in the FETO population, where surfactant recipients have more favorable survival and comparable outcomes. When controlling for defect severity or surfactant usage, as a proxy for respiratory status, surfactant recipients that underwent FETO trended toward improved survival and decreased ECMO use. CONCLUSIONS: Surfactant administration is not associated with increased morbidity and mortality and may be beneficial in CDH patients that have undergone FETO.

Arrhythmias in Critically Ill Surgical and Non-surgical Patients: A National Propensity-Matched Study.

BACKGROUND: Arrhythmias are common in critically ill patients, though the impact of arrhythmias on surgical patients is not well delineated. We aimed to characterize mortality following arrhythmias in critically ill patients. METHODS: We performed a propensity-matched retrospective analysis of intensive care unit (ICU) patients from 2007 to 2017 in the Cerner Acute Physiology and Chronic Health Evaluation database. We compared outcomes between patients with and without arrhythmias and those with and without surgical indications for ICU admission. We also modeled predictors of arrhythmias in surgical patients. RESULTS: 467,951 patients were included; 97,958 (20.9%) were surgical patients. Arrhythmias occurred in 1.4% of the study cohorts. Predictors of arrhythmias in surgical patients included a history of cardiovascular disease (odds ratio [OR] 1.35, 95% confidence interval [CI95] 1.11-1.63), respiratory failure (OR 1.48, CI95 1.12-1.96), pneumonia (OR 3.17, CI95 1.98-5.10), higher bicarbonate level (OR 1.03, CI95 1.01-1.05), lower albumin level (OR 0.79, CI95 0.68-0.91), and vasopressor requirement (OR 27.2, CI95 22.0-33.7). After propensity matching, surgical patients with arrhythmias had a 42% mortality risk reduction compared to non-surgical patients (risk ratio [RR] 0.58, CI 95 0.43-0.79). Predicted probabilities of mortality for surgical patients were lower at all ages. CONCLUSIONS: Surgical patients with arrhythmias are at lower risk of mortality than non-surgical patients. In this propensity-matched analysis, predictors of arrhythmias in critically ill surgical patients included a history of cardiovascular disease, respiratory complications, increased bicarbonate levels, decreased albumin levels, and vasopressor requirement. These findings highlight the differential effect of arrhythmias on different cohorts of critically ill populations.

Association of Socioeconomic Status with Empowerment, Depression, and Anxiety in Pregnancies Complicated by Fetal Surgical Anomalies.

BACKGROUND: Women with pregnancies complicated by fetal surgical anomalies experience significant psychosocial burden. There remains a need to determine the impact that socioeconomic status has on maternal empowerment, anxiety, and depression. METHODS: A survey study was conducted from 5/2021-5/2022 to quantify empowerment, anxiety, and depression in women with fetal surgical anomalies. Surveys administered included Pregnancy Related Empowerment Scale (PRES), Patient Empowerment Scale (PES), State Trait Anxiety Inventory (STAI), and Depression Anxiety and Stress Scale (DASS). Two-sample t-test was used to compare survey scores across socioeconomic groups. RESULTS: Seventy-four patients were recruited. Mothers more commonly preferred English as primary language (n = 61, 82%) and were non-Hispanic (n = 43, 58%). Lower empowerment scores were observed in Hispanic mothers (PRES, p = 0.03; PES, p = 0.04) and mothers who preferred Spanish (PRES, p = 0.04; PES, p = 0.06) as primary language. Both non-Hispanic (p = 0.88) and English speaking (p = 0.75) women had higher STAI scores, but neither was significantly different. DASS was not significantly higher for Hispanic (p = 0.79) or Spanish speaking mothers (p = 0.47). CONCLUSION: Hispanic and Spanish speaking women with pregnancies complicated by fetal surgical anomalies have significantly decreased empowerment scores. These findings suggest a need for development of culturally competent, targeted interventions to improve maternal empowerment in this high-risk population. LEVEL OF EVIDENCE: Level II. TYPE OF STUDY: Cross-Sectional Survey Study.

Predictors of Poor Postoperative Outcomes in Pediatric Surgery Patients in Rural Ghana.

BACKGROUND/PURPOSE: Perioperative complications cause significant pediatric morbidity and mortality in low- and lower middle -income countries. This study investigates factors associated with prolonged length of stay, 90-day readmission and in-hospital mortality among pediatric patients at Eastern Regional Hospital (ERH) in Ghana. METHODS: This is a retrospective review of perioperative morbidity and mortality in children < 18 years at ERH in Koforidua, Ghana. All pediatric surgeries performed between January 2015 and December 2017 were included in this study. Univariate analysis was performed using Pearson's chi-square tests or Fisher's exact tests. Variables that were significant on univariate analysis were included in multivariable logistic regression models adjusted for age and gender. RESULTS: We analyzed 468 patients < 18 years of age with a median length of stay (LOS) of 3 days. The 90-day readmission and in-hospital mortality rates were 138 and 17 per 1000 patients, respectively. The most common procedures were herniorrhaphy (19 %) and appendectomy (15 %). Gastrointestinal surgery, surgical trauma, surgical infection and lack of insurance were significantly associated with prolonged LOS. Young age and female gender were significantly associated with in-hospital mortality. Malaria was significantly associated with 90-day readmission. CONCLUSIONS: Malaria infection is a significant risk factor for readmission, which should be investigated and treated in pediatric surgical patients in rural Ghana. Ensuring that all patients have insurance may result in shorter hospital stays. Provision of laparoscopic equipment may reduce hospital stays for patients undergoing gastrointestinal surgery. Expansion of the surgical work force, particularly pediatric surgeons, could improve perioperative survival in the very young population. LEVEL OF EVIDENCE: Retrospective comparative study.

Risk factors of perioperative mortality from complicated peptic ulcer disease in Africa: systematic review and meta-analysis.

Introduction: In 2013, peptic ulcer disease (PUD) caused over 300 000 deaths globally. Low-income and middle-income countries are disproportionately affected. However, there is limited information regarding risk factors of perioperative mortality rates in these countries. Objective: To assess perioperative mortality rates from complicated PUD in Africa and associated risk factors. Design: We performed a systematic review and a random-effect meta-analysis of literature describing surgical management of complicated PUD in Africa. We used subgroup analysis and meta-regression analyses to investigate sources of variations in the mortality rates and to assess the risk factors contributing to mortality. Results: From 95 published reports, 10 037 patients underwent surgery for complicated PUD. The majority of the ulcers (78%) were duodenal, followed by gastric (14%). Forty-one per cent of operations were for perforation, 22% for obstruction and 9% for bleeding. The operations consisted of vagotomy (38%), primary repair (34%), resection and reconstruction (12%), and drainage procedures (6%). The overall PUD mortality rate was 6.6% (95% CI 5.4% to 8.1%). It increased to 9.7% (95% CI 7.1 to 13.0) when we limited the analysis to studies published after the year 2000. The correlation was higher between perforated PUD and mortality rates (r=0.41, p<0.0001) than for bleeding PUD and mortality rates (r=0.32, p=0.001). Non-significant differences in mortality rates existed between sub-Saharan Africa (SSA) and North Africa and within SSA. Conclusion: Perioperative mortality rates from complicated PUD in Africa are substantially high and could be increasing over time, and there are possible regional differences.
