Risk of Surgical Intervention in Children with Diagnoses of Cancer and Preoperative Malnutrition: A National Analysis.

BACKGROUND: Perioperative nutrition is a critical component of appropriate healing and recovery after surgery. We sought to identify perioperative risk in children with cancer and low preoperative hypoalbuminemia undergoing surgical intervention. METHODS: We queried the 2015-2019 NSQIP-Peds datasets for children with a primary diagnosis of renal or hepatic malignancy undergoing surgical resection. Postoperative outcomes were evaluated for comparative risk between patients with low albumin (albumin<3.0 g/dL) and normal albumin within 30 days of their surgical procedure. Univariate analysis and multivariable logistic regression were conducted to identify perioperative risk in patients with hypoalbuminemia. RESULTS: We identified 360 children with primary diagnosis of hepatic malignancy and 896 children with renal malignancy undergoing surgical resection. Of these, 77 children had hypoalbuminemia. Patients with renal or hepatic malignancy diagnosis and low albumin levels were more likely to experience postoperative dehiscence, need for TPN at discharge, postoperative bleeding or transfusion, unplanned reoperation, and unplanned readmission, based on univariate analysis (all P > 0.05). Postoperative bleeding, need for nutritional support at discharge, and unplanned readmission were each associated with hypoalbuminemia. CONCLUSION: We demonstrate that low preoperative albumin is associated with significant perioperative risk. More attention should focus on perioperative nutritional status of children with cancer who are undergoing major resections.

Methicillin-resistant Staphylococcus aureus nasal colonization in children with cerebral palsy.

A retrospective cohort of children admitted to the pediatric intensive care unit (PICU) with cerebral palsy was matched 1:3 by age and admission year to determine odds of methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization. Adjusted odds of MRSA nasal colonization at PICU admission were 2.6-fold higher among children with cerebral palsy.

Use of a Structured Observation Tool to Promote Medical Student Engagement in Trauma Resuscitations.

OBJECTIVE: We describe a novel approach to promoting medical student learning and engagement during trauma resuscitation with implementation of a structured observation and debriefing tool. DESIGN: In the context of a multifaceted quality improvement effort in our emergency room, we implemented a structured trauma observation tool (SOT) for medical students based on ATLS trauma guidelines. The SOT reflects the American College of Surgeons and Association for Surgical Education (ACS/ASE) trauma evaluation module for medical students. Two medical students from our quality improvement working group undertook a proof-of-concept study to determine whether the SOT facilitated accurate observations of trauma resuscitations and promoted educational debriefs with precepting providers. Results were encouraging, so the tool was implemented for elective use on surgical clerkships. Clerkship students who used the SOT were given the opportunity to share its impact on their experience. Institutional Review Board approval was obtained under Pro00109569. SETTING: A large level 1 trauma center at an academic hospital in the southeastern United States. PARTICIPANTS: An interdisciplinary working group including surgeons, emergency medicine physicians, nurses, and students developed the observation tool. Two medical students from this team showed that the tool was effective at guiding observations and facilitating debriefs prior to its broader implementation on the general surgery clerkship. RESULTS: A total of 630 resuscitation tasks were observed during 15 trauma activations prior to implementation on the surgery clerkship. There was over 97% agreement between students observations and evaluating physicians self-reporting on which tasks were completed. Tasks on which there was disagreement were discussed to aid student learning. The tool was implemented for elective use on the surgery clerkship where students reported positive experiences. CONCLUSIONS: Early data suggest that this structured observation tool facilitates accurate trauma assessment observations and provides an opportunity for high-yield debriefs with the evaluating physician. This promotes student comprehension of ATLS principles. The SOT is being implemented as a pedagogic tool for students on the surgery clerkship to guide their observations, improve comprehension of decisions made in a hyperacute setting, and offer real time feedback as part of their learning in the trauma bay. The tool appears to be a valuable supplement which supports the ACS/ASE curriculum.

Surgical Site Infection in Children with Neuromuscular Disorders after Laparoscopic Gastrostomy: A Propensity-Matched National Surgical Quality Improvement Program Pediatrics Database Analysis.

Background: Prior studies have demonstrated that children with neuromuscular scoliosis have a higher incidence of infection after spine surgery. The purpose of the study is to determine whether children with neuromuscular disorders (NMDs) have higher rate of superficial surgical site infection (SSI) or increased hospital length of stay (LOS) compared with children without NMDs following laparoscopic gastrostomy creation, a common pediatric general surgery operation. Patients and Methods: We performed a retrospective propensity-matched analysis of laparoscopic gastrostomy creation in children from National Surgical Quality Improvement Program Pediatrics database (NSQIP-P) 2018-2019. Patients were stratified based on NMD status. We performed multivariable logistic regression and ordered logistic regression to estimate the odds ratio of superficial SSI within 30 days of surgery and increased LOS. Results: We screened 252,367 patients from the NSQIP-P 2018-2019 dataset. After applying inclusion and exclusion criteria and 1:1 propensity score-matching, there were 991 children with NMDs and 991 children without NMDs. Children with NMDs had higher prevalence of superficial SSI within 30 days of gastrostomy creation: 36 (3.63%) versus 18 (1.82%); p = 0.013. Children with NMDs had increased odds of having a superficial SSI within 30 days of laparoscopic gastrostomy tube (G-tube) placement compared with children without NMD (odds ratio [OR], 2.01; 95% confidence interval [CI], 1.13-3.58; p = 0.018). There was no difference in LOS based on NMD status. Conclusion: Children with NMDs have two-fold increased odds of superficial SSI after laparoscopic gastrostomy creation compared with children without NMDs. Children with NMDs should be the aim of targeted quality improvement initiatives to reduce infection risks.

Influence of Socioeconomic and Environmental Determinants of Health on Human Infection and Colonization with Antibiotic-Resistant and Antibiotic-Associated Pathogens: A Scoping Review.

Background: Antibiotic-resistant and antibiotic-associated pathogens are commonly encountered by surgeons. Pathogens such as methicillin-resistant Staphylococcus aureus (MRSA), Clostridioides difficile infection (CDI), and carbapenem-resistant Enterobacteriaceae (CRE) result in considerable human morbidity, mortality, and excess healthcare expenditure. Human colonization or infection can result from exposure to these pathogens across a range of domains both inside and outside of the built healthcare environment, exposure that may be influenced by socioeconomic and environmental determinants of health, the importance of which has not been investigated fully. Methods: We performed a scoping review of published literature describing potential socioeconomic and environmental variables that may increase the likelihood of human infection or colonization with common antibiotic-resistant or antibiotic-associated pathogens, using MRSA, CDI, and CRE as examples. Results: We identified 7,916 articles meeting initial search criteria. Of these, 101 provided supportive evidence of socioeconomic and environmental determinants of human infection or colonization and were included in the scoping review after abstract and full-text screening. Sixty-seven evaluated MRSA, nine evaluated CRE, and 29 evaluated CDI. Twenty-nine articles evaluated exposure to livestock or companion animals; 28, exposure to antibiotics; 20, impact of socioeconomic factors, education level, or race; 14, the influence of temperature, humidity, or season; 13, the effect of travel or human population migration; 11, exposure to built healthcare environments; and eight assessed impact of population density or urbanization. Conclusions: Although articles outlining socioeconomic and environmental drivers of antibiotic-resistant and antibiotic-associated infection are still disconcertedly few, evidence of such associations are overwhelming for MRSA and CDI and supportive for CRE. Additional research is needed to investigate the role and importance of different potential socioeconomic and environmental drivers of antibiotic-resistant and antibiotic-associated infections and colonization in humans.

Medical transport-associated infection: Review and commentary making a case for its legitimacy.

The purpose of this article is to summarize existing literature about healthcare-associated infection (HAI) in the medical transport environment and to define the term medical transport-associated infection (MTAI) to unify all previous work under a single umbrella with the objective of providing a standardized definition for future research. A review of the literature yielded 34 relevant articles. These studies show that there are pathogens in the ambulance environment, that emergency medical services (EMS) personnel do not regularly comply with hygiene practices, and that patients are potentially affected by HAI as a direct result of ambulance exposure. Prospective studies must be conducted to truly understand the impact that ambulance exposure has on HAIs. MTAI is a subset of HAI and is defined as any infection acquired as a direct effect of exposure in a medical transport setting.

Risk of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) acquisition during ambulance transport: A retrospective propensity-score-matched cohort analysis.

OBJECTIVE: To estimate the relative risk (RR) of developing methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) colonization or infection within 30 days of ambulance transport. METHODS: We performed a retrospective cohort study of patients with a principal diagnosis of chest pain presenting to our emergency department (ED) over a 4-year period. Patients were included if they presented from and were discharged to nonhealthcare locations without being admitted. Encounters were stratified by arrival mechanism: ambulance versus private vehicle. We performed propensity score matching and multivariable logistic regression to estimate the RR for the primary outcome. RESULTS: In total, 321,229 patients had ED encounters during the study period. After applying inclusion criteria and propensity score matching, there were 11,324 patients: 3,903 in the ambulance group and 7,421 in the unexposed group. Among them, 12 patients (0.11%) had the outcome of interest, including 9 (0.08%) with MRSA and 3 (0.03%) with VRE. The 30-day prevalence of MRSA or VRE was larger in the ambulance group than in the unexposed group: 8 (0.20%) and 4 (0.05%), respectively (P = .02). Patients who presented to the ED via ambulance were almost 4 times more likely to have MRSA or VRE within 30 days of their encounter (RR, 3.72; 95% CI, 1.09-12.71; P = .04). CONCLUSIONS: Our cohort study is the first to demonstrate an association between ambulance exposure and pathogen incidence, representing the first step in evaluating medical-transport-associated infection burden to eventually develop interventions to address it.

Racial and ethnic disparities over time in the treatment and mortality of women with gynecological malignancies.

OBJECTIVE: To examine temporal trends in treatment and survival among black, Asian, Hispanic, and white women diagnosed with endometrial, ovarian, cervical, and vulvar cancer. METHODS: Using the National Cancer Database (2004-2014), we identified women diagnosed with endometrial, ovarian, cervical, and vulvar cancer. For each disease site, we analyzed race/ethnicity-specific trends in receipt of evidence-based practices. Professional societies' recommendations were used to define these practices. Using data from the Surveillance, Epidemiology, and End Results Program (2000-2009) we analyzed trends in 5-year survival. RESULTS: Throughout the study period black (64.8%) and Hispanic (68.3%) women were less likely to undergo lymphadenectomy for stage I ovarian cancer compared to Asian (79.5%) and white patients (74.6%). Black women were the least likely group to undergo lymphadenectomy in all periods. Among patients with stage II-IV ovarian cancer, 76.6% of white and Asian women received both surgery and chemotherapy, compared to 70.8% of black and 73.9% Hispanic women. Hispanic women with deeply invasive or high-grade stage I endometrial cancer underwent lymphadenectomy less frequently (74.5%) than all other groups (80.7%). Black women were less likely to have chemo-radiotherapy for stage IIB-IVA cervical cancer (75.6% versus 80.4% of all others). Black women were also less likely to have a surgical lymph node evaluation for vulvar cancer (58.8% versus 63.5% of all others). Among women diagnosed with ovarian, endometrial, and cervical cancer, black women had lower five-year survival than other groups. CONCLUSION: Significant racial disparities persist in the delivery of evidence-based care. Black women with ovarian, endometrial, and cervical cancer continue to experience higher cancer-specific mortality than other groups.
