A Life Cycle Assessment of Reusable and Disposable Surgical Caps.

INTRODUCTION: Surgical cap attire plays an important role in creating a safe and sterile environment in procedural suites, thus the choice of reusable versus disposable caps has become an issue of much debate. Given the lack of evidence for differences in surgical site infection (SSI) risk between the two, selecting the cap option with a lower carbon footprint may reduce the environmental impact of surgical procedures. However, many institutions continue to recommend the use of disposable bouffant caps. METHODS: ISO-14044 guidelines were used to complete a process-based life cycle assessment to compare the environmental impact of disposable bouffant caps and reusable cotton caps, specifically focusing on CO2 equivalent (CO2e) emissions, water use and health impacts. RESULTS: Reusable cotton caps reduced CO2e emissions by 79% when compared to disposable bouffant caps (10 kg versus 49 kg CO2e) under the base model scenario with a similar reduction seen in disability-adjusted life years. However, cotton caps were found to be more water intensive than bouffant caps (67.56 L versus 12.66 L) with the majority of water use secondary to production or manufacturing. CONCLUSIONS: Reusable cotton caps have lower total lifetime CO2e emissions compared to disposable bouffant caps across multiple use scenarios. Given the lack of evidence suggesting a superior choice for surgical site infection prevention, guidelines should recommend reusable cotton caps to reduce the environmental impact of surgical procedures.

Association of social determinants of health-related diagnosis codes with postoperative outcomes.

BACKGROUND: The association of an individual's social determinants of health-related problems with surgical outcomes has not been well-characterized. The objective of this study was to determine whether documentation of social determinants of a health-related diagnosis code (Z code) is associated with postoperative outcomes. METHODS: This retrospective cohort study included surgical cases from a single institution's national surgical quality improvement program (NSQIP) clinical registry from October 2015 to December 2021. The primary predictor of interest was documentation of a Z code for social determinants of health-related problems. The primary outcome was 30-day postoperative morbidity. Secondary outcomes included postoperative length of stay, disposition, and 30-day postoperative mortality, reoperation, and readmission. Multivariable regression models were fit to evaluate the association between the documentation of a Z code and outcomes. RESULTS: Of 10,739 surgical cases, 348 patients (3.2%) had a documented social determinants of health-related Z code. In multivariable analysis, documentation of a Z code was associated with increased odds of morbidity (20.7% vs. 9.9%; adjusted odds ratio [aOR], 1.88; 95% confidence interval [CI], 1.39-2.53), length of stay (median, 3 vs. 1 day; incidence rate ratio, 1.49; 95% CI, 1.33-1.67), odds of disposition to a location other than home (11.3% vs. 3.9%; aOR, 2.86; 95% CI, 1.89-4.33), and odds of readmission (15.3% vs. 6.1%; aOR, 1.99; 95% CI, 1.45-2.73). CONCLUSIONS: Social determinants of health-related problems evaluated using Z codes were associated with worse postoperative outcomes. Improved documentation of social determinants of health-related problems among surgical patients may facilitate improved risk stratification, perioperative planning, and clinical outcomes.

Surgeon Understanding and Perceptions of Social Determinants of Health.

INTRODUCTION: Social determinants of health impact surgical outcomes. Characterization of surgeon understanding of social determinants of health is necessary prior to implementation of interventions to address patient needs. The study objective was to explore understanding, perceived importance, and practices regarding social determinants of health among surgeons. METHODS: Surgical residents and attending surgeons at a single academic medical center completed surveys regarding social determinants of health. We conducted semi-structured interviews to further explore understanding and perceived importance. A conceptual framework from the World Health Organization (WHO) Commission on Social Determinants of Health informed the thematic analysis. RESULTS: Survey response rate was 47.9% (n = 69, 44 residents [63.8%], 25 attendings [36.2%]). Respondents primarily reported good (n = 29, 42.0%) understanding of social determinants of health and perceived this understanding to be very important (n = 42, 60.9%). Documentation occurred seldom (n = 35, 50.7%), and referrals occurred seldom (n = 26, 37.7%) or never (n = 20, 29.0%). Residents reported a higher rate of prior training than attendings (95.5% versus 56.0%, P < 0.001). Ten interviews were conducted (six residents, four attendings). Residents demonstrated greater understanding of socioeconomic positions and hierarchies shaped by structural mechanisms than attendings. Both residents and attendings demonstrated understanding of intermediary determinants of health status and linked social determinants to impacting patients' health and well-being. Specific knowledge gaps were identified regarding underlying structural mechanisms including the social, economic, and political context that influence an individual's socioeconomic position. CONCLUSIONS: Self-reported understanding and importance of social determinants of health among surgeons were high. Interviews revealed gaps in understanding that may contribute to limited practices.

Operating Room Recycling: Opportunities to Reduce Carbon Emissions Without Increases in Cost.

BACKGROUND: The healthcare industry is a major contributor to greenhouse gas emissions. Within the hospital, operating rooms are responsible for the largest proportion of emissions due to high resource utilization and waste generation. Our aim was to generate estimates of greenhouse gas emissions avoided and cost implications following implementation of a recycling program across operating rooms at our freestanding children's hospital. METHODS: Data were collected from three commonly performed pediatric surgical procedures: circumcision, laparoscopic inguinal hernia repair, and laparoscopic gastrostomy tube placement. Five cases of each procedure were observed. Recyclable paper and plastic waste was weighed. Emission equivalencies were determined using the Environmental Protection Agency Greenhouse Gas Equivalencies Calculator. Institutional cost of waste disposal was $66.25 United States Dollars (USD)/ton for recyclable waste and $67.00 USD/ton for solid waste. RESULTS: The proportion of recyclable waste ranged from 23.3% for circumcision to 29.5% for laparoscopic gastrostomy tube placement. The amount of waste redirected from landfill to a recycling stream could result in annual avoidance of 58,500 to 91,500 kg carbon dioxide equivalent emissions, or 6583 to 10,296 gallons of gasoline. Establishing a recycling program would not require additional cost and could lead to modest cost savings (range $15 to 24 USD/year). CONCLUSIONS: Incorporation of recycling into operating rooms has the potential to reduce greenhouse gas emissions without increased cost. Clinicians and hospital administrators should consider operating room recycling programs as they work towards improved environmental stewardship. LEVEL OF EVIDENCE: Level VI - evidence form a single descriptive or qualitative study.

Environmental Impact and Cost Savings of Operating Room Quality Improvement Initiatives: A Scoping Review.

BACKGROUND: Operating rooms are major contributors to a hospital's carbon footprint due to the large volumes of resources consumed and waste produced. The objective of this study was to identify quality improvement initiatives that aimed to reduce the environmental impact of the operating room while decreasing costs. STUDY DESIGN: A literature search was performed using PubMed, Scopus, CINAHL, and Google Scholar and included broad terms for "operating room," "costs," and "environment" or "sustainability." The "triple bottom line" framework, which considers the environmental, financial, and social impacts of interventions to guide decision making, was used to inform data extraction. The studies were then categorized using the 5 "Rs" of sustainability-refuse, reduce, reuse, repurpose, and recycle-and the impacts were discussed using the triple bottom line framework. RESULTS: A total of 23 unique quality improvement initiatives describing 28 interventions were included. Interventions were categorized as "refuse" (n = 11; 39.3%), "reduce" (n = 8; 28.6%), "reuse" (n = 3; 10.7%), and "recycle" (n = 6; 21.4%). While methods of measuring environmental impact and cost savings varied greatly among studies, potential annual cost savings ranged from $873 (intervention: education on diverting recyclable materials from sharps containers; environmental impact: 11.4 kg sharps waste diverted per month) to $694,141 (intervention: education to reduce regulated medical waste; environmental impact: 30% reduction in regulated medical waste). CONCLUSIONS: Quality improvement initiatives that reduce both cost and environmental impact have been successfully implemented across a variety of centers both nationally and globally. Surgeons, healthcare practitioners, and administrators interested in environmental stewardship and working toward a culture of sustainability may consider similar interventions in their institutions.

Is the Laparotomy Here to Stay? A Review of the Disadvantages of Laparoscopy.

Minimally invasive procedures have seen increasing utilization in the pediatric patient population since the 1990s. Most thoracic and abdominal operations in pediatric surgery can be performed in a minimally invasive manner including those performed in neonates and infants. Thoracoscopic or laparoscopic operations can reduce hospital length of stay, minimize postoperative pain, and lead to more aesthetic results. However, it is important to be aware of the inherent risks, limitations, and adverse effects associated with these thoracoscopic and laparoscopic techniques, particularly in special populations. In this article, we will review the risks and limitations of laparoscopy in pediatric patients such as cost, operative time, reduced effectiveness, air embolism, hypercarbia, hypothermia, and access-related injuries.

Longitudinal Outcomes After Surgical Repair of Postinfarction Ventricular Septal Defect in the Medicare Population.

BACKGROUND: Patients undergoing post infarction ventricular septal defect repair are at high risk for early morbidity and mortality, but little is known about subsequent clinical events. This study uses short-term clinical data from The Society of Thoracic Surgeons National Database linked with Medicare data to examine longer term outcomes in these patients. METHODS: This was a retrospective review of The Society of Thoracic Surgeons National Database to link with Medicare data all adults (≥65 years) who underwent ventricular septal defect repair after a myocardial infarction between 2008 and 2012. The primary outcome was 1-year mortality. Risk factors for 1-year survival were modeled using a multivariable Cox regression. RESULTS: Five hundred thirty-seven patients were identified using The Society of Thoracic Surgeons database and Medicare linkage. Median age was 74 years, and 277 patients (52%) were men. One hundred ninety-two patients (36%) were supported preoperatively with an intraaortic balloon pump. Surgical status was emergent or salvage in 138 (26%), and 158 patients (29%) died within 30 days and 207 (39%) within 1 year. Among patients who survived to hospital discharge, 44% were discharged to a facility and 172 (32%) experienced at least 1 all-cause readmission within 1 year. Unadjusted 1-year mortality rates were 13% for elective patients and 69% for emergency status (P < .01). On multivariable analysis emergency/salvage status, older age, and concomitant coronary artery bypass grafting were independently associated with worse 1-year survival. CONCLUSIONS: These data suggest the greatest mortality risk in this patient population occurs in the first 30 days. Emergency or salvage status strongly predicts 1-year mortality. Optimizing physiologic derangements before operative repair may be considered when possible in this subgroup of patients.

Inequalities in the use of helmets by race and payer status among pediatric cyclists.

BACKGROUND: Despite nationwide campaigns to increase the use of helmets among pediatric cyclists, many children continue to be injured while riding without a helmet. To determine where programs and policies intended to promote helmet use should be directed, we surveyed a large national dataset to identify variables associated with helmet use. METHODS: The National Trauma Data Bank was queried during the years 2007, 2010, and 2011 for children younger than the age of 16 years who were involved in a bicycle accident. Children were grouped based on whether they had a helmet on during the accident. A multivariable logistic mixed-effects model was utilized to determine factors associated with helmet use. RESULTS: Of the 7,678 children included in the analysis, 1,695 (22.1%) were wearing a helmet during their accident. On unadjusted analysis, nonhelmeted riders were more likely to be older (median age 11 years vs 10 years, P < .001), black (10.1% vs 3.7%, P < .001) or insured by Medicaid (32.8% vs 14.3%, P < .001). After adjustment, black children were still less likely to have had worn a helmet compared with white children (adjusted odds ratio 0.38, 95% confidence interval 0.28-0.50). Children on Medicaid were also less likely to have been wearing a helmet compared to children with private insurance (adjusted odds ratio 0.33, 95% confidence interval 0.28-0.39). CONCLUSION: Children who are black or who are on Medicaid are less likely to be wearing a helmet when involved in a bicycle accident than white children or children with private insurance, respectively. Future efforts to promote helmet use should be directed towards these groups.

Use of patient registries and administrative datasets for the study of pediatric cancer.

Analysis of data from large administrative databases and patient registries is increasingly being used to study childhood cancer care, although the value of these data sources remains unclear to many clinicians. Interpretation of large databases requires a thorough understanding of how the dataset was designed, how data were collected, and how to assess data quality. This review will detail the role of administrative databases and registry databases for the study of childhood cancer, tools to maximize information from these datasets, and recommendations to improve the use of these databases for the study of pediatric oncology.
