The Utilisation of INR to identify coagulopathy in burn patients

Studies conflict on the significance of burn-induced coagulopathy. We posit that burn-induced coagulopathy is associated with injury severity in burns. Our purpose was to characterize coagulopathy profiles in burns and determine relationships between % total burn surface area (TBSA) burned and coagulopathy using the International Normalized Ratio (INR). Burned patients with INR values were identified in the TriNetX database and analyzed by %TBSA burned. Patients with history of transfusions, chronic hepatic failure, and those on anticoagulant medications were excluded. Interquartile ranges for INR in the burned study population were 1.2 (1.0-1.4). An INR of ≥ 1.5 was used to represent those with burn-induced coagulopathy as it fell outside the 3rd quartile. The population was stratified into subgroups using INR levels <1.5 or ≥1.5 on the day of injury. Data are average ± SD analyzed using chi-square; p < .05 was considered significant. There were 7,364 burned patients identified with INR <1.5, and 635 had INR ≥1.5. Comparing TBSA burned groups, burn-induced coagulopathy significantly increased in those with ≥20% TBSA; p = .048 at 20-29% TBSA, p = .0005 at 30-39% TBSA, and p < .0001 for 40% TBSA and above. Age played a significant factor with average age for those with burn-induced coagulopathy 59 ± 21.5 years and 46 ± 21.8 for those without (p < .0001). After matching for age, TBSA, and demographics, the risk of 28 day-mortality was higher in those with burn-induced coagulopathy compared to those without (risk difference 20.9%, p < .0001) and the odd ratio with 95% CI is 4.45 (3.399-5.825). Investigation of conditions associated with burn-induced coagulopathy showed the effect of heart diseases to be significant; 53% of patients with burn-induced coagulopathy had hypertension (p < .0001). Burn-induced coagulopathy increases with %TBSA burned. The information gained firmly reflects a link between %TBSA and burn-induced coagulopathy, which could be useful in prognosis and treatment decisions.

Retrospective outcomes analysis of tracheostomy in a paediatric burn population

INTRODUCTION

Previous analyses of tracheostomy in paediatric burns was hindered by a lack of multi-institution or nationwide analysis. This study aims to explore the effects of tracheostomy in paediatric burn patients in such an analysis. De-identified data was obtained from the TriNetX Research Network database.

METHODS

Two cohorts were identified using ICD and CPT codes: paediatric burn patients with tracheostomy (cohort 1) and paediatric burn patients without tracheostomy (cohort 2). Cohorts were matched according to age at diagnosis and pulmonary condition, specifically influenza and pneumonia, respiratory failure, acute upper respiratory infection, and pulmonary collapse. Cohorts were also matched for age at burn diagnosis and surface area burned. Several parameters including infection following a procedure, sepsis, volume depletion, respiratory disorders, laryngeal disorders, pneumonia, and other metrics were also compared.

RESULTS

A total of 152 patients were matched according to age and pulmonary condition. Cohort 1 and cohort 2 had a mean age of 4.45 ± 4.06 and 4.39 ± 3.99 years, respectively. Matched patients with tracheostomy had a higher risk for pneumonia, respiratory failure, other respiratory disorders, diseases of the vocal cord and larynx, sepsis, volume depletion, pulmonary edema, and respiratory arrest. The risk ratios for these outcomes were 2.96, 3.5, 3.13, 3.9, 2.5, 2.5, 3.3, and not applicable. Analysis of longitudinal outcomes of paediatric burn patients with tracheostomy vs. those without demonstrated the tracheostomy cohort suffered much worse morbidity and experienced higher health burden across several metrics.

CONCLUSION

The potential benefits of tracheostomy in paediatric burn patients should be weighed against these outcomes.

Reviewing ACGME Plastic Surgery Fellowship Case Logs: Is Surgical Experience Increasing?

INTRODUCTION

Over the last decade, there has been a 32% decrease in independent plastic surgery fellowships. The growing prevalence of 6-year integrated plastic surgery residencies, duty hour restrictions, and new subspecialty training fellowships for general surgeons have changed the training experience of plastic surgery fellows.

METHODS

A retrospective review of the Accreditation Council for Graduate Medical Education (ACGME) case logs for graduating fellows of independent plastic surgery fellowships in the United States was conducted from 2011 to 2019. A linear regression analysis was conducted for each case log code and category, and a 95% level of confidence was assumed (α = 0.05).

RESULTS

In 2011, 141 residents from 69 programs graduated with an average of 1469.7 cases. In 2019, 84 residents from 47 programs graduated with an average of 1952 cases. Index procedures significantly increased overall during the 9 y (P < 0.001). Categorical cases increased in esthetics (P < 0.001), including facelift, browlift, blepharoplasty, and more. Categorical cases increased in reconstructive surgery (P < 0.001), including treatment of deformities of the skin, lower extremities, and trunk, nerve decompression, and hand reconstruction. In breast procedures, an increase was seen in the reduction of mammoplasty, reconstruction, and treatment of other breast deformities. In head and neck procedures, an increase was seen in resection of head and neck neoplasms and secondary cleft lip repair. Decreases in procedural numbers were seen in primary cleft lip repair and hand reconstruction by primary closure.

CONCLUSIONS

Despite a 32% decline in the number of independent plastic surgery fellowships over the last 9 y, plastic surgery fellows are obtaining significantly more surgical experience, both in esthetic and reconstructive surgery.

Value Analysis of Central Line Simulation-Based Education

BACKGROUND

Central line-associated bloodstream infections (CLABSIs) are preventable complications that pose a significant health risk to patients and place a financial burden on hospitals. Central line simulation-based education (SBE) efforts vary widely in the literature. The aim of this study was to perform a value analysis of published central line SBE and develop a refined method of studying central line SBE.

METHODS

A database search of PubMed Central and Cumulative Index to Nursing and Allied Health Literature (CINAHL) was performed for articles mentioning "Cost and CLABSI," "Cost and Central line Associated Bloodstream Infections," and "Cost and Central Line" in their abstract and article body. Articles chosen for qualitative synthesis mentioned "simulation" in their abstract and article body and were analyzed based on the following criteria: infection rate before vs. after SBE, cost of simulation, SBE design including simulator model used, and learner analysis.

RESULTS

Of 215 articles identified, 23 were analyzed, 10 (43.48%) discussed cost of central line simulation with varying criteria for cost reporting, 8 (34.8%) numerically discussed central line complication rates (7 CLABSIs and 1 pneumothorax), and only 3 (13%) discussed both (Figure). Only 1 addressed the true cost of simulation (including space rental, equipment startup costs, and faculty salary) and its longitudinal effect on CLABSIs.

CONCLUSION

Current literature on central line SBE efforts lacks value propositions. Due to the lack of value-based data in the area of central line SBE, the authors propose a cost reporting standard for use by future studies reporting central line SBE costs.

Development of a Low-cost, High-fidelity Skin Model for Suturing

BACKGROUND

In a survey of students at our institution, suturing was the most desired workshop for simulation; however, cost, quality, and availability of skin pads is often prohibitive for suturing workshops. In-hospital fabrication may be utilized to manufacture noncommercial, high-fidelity, and low-cost simulation models. We describe the production, value, and face validation of our simulated skin model.

MATERIALS AND METHODS

Using an in-hospital fabrication laboratory, we have developed a model for skin and subcutaneous tissue. Our model uses a variety of commercially available materials to simulate the epidermis, dermis, subcutaneous fat, fascia, and muscle. A cost analysis was performed by comparing it with other commonly used commercial skin models. Expert surgeons assessed the material characteristics, durability, and overall quality of our model in comparison with other commercial models.

RESULTS

The materials cost of our novel skin pad model was 30.9% of the mean cost of five different commonly used foam and silicone-based commercial skin models. This low-cost model is more durable than the commercial models, does not require skin pad holders, and is of higher fidelity than the commercial products. In addition to skin closure, our model may be used to simulate fascial closure or fasciotomy.

CONCLUSIONS

Model creation using in-hospital workspaces is an effective strategy to decrease cost while improving quality of surgical simulation. Our methods for creation of an inexpensive and high-fidelity skin pad may be purposed for several soft tissue models.
