Impact of Environmental Noise Levels on Endotracheal Intubation Performance Among Pediatric Emergency Providers: A Simulation Study.

BACKGROUND: The emergency department is a stressful workplace environment with environmental stimuli and distractions, including noise. This has potential effects on perceived stress for providers and critical procedure performance. OBJECTIVE: This study aimed to characterize the impact of environmental noise levels on the time to intubate, the quality of intubation, and physiologic stress response in pediatric emergency department providers. METHODS: This was a randomized control simulation-based study in which experienced pediatric providers intubated an adult manikin 3 times while experiencing 3 different ambient noise levels (60, 75, 80 dB) in random order. Participants' times to intubate were measured, as was the endotracheal tube depth. The quality of each intubation attempt was assessed via video review against a standardized checklist. Lastly, participants' heart rates were monitored in real time to assess for physiologic stress response. Differences in performance were analyzed using a repeated-measures analysis of variance. RESULTS: No significant difference was found between noise levels and time to intubate (P = 0.19), although each subsequent attempt shortened the time to intubate (P = 0.01). Physiological heart rate changes did not differ by noise level (P = 0.35). Subjectively, "time and economy of motion" and "overall performance" did not differ by noise level but did improve for each subsequent attempt number (P < 0.046). CONCLUSIONS: Intubation performance improved with attempt number, but no differences in performance were seen between noise levels. This suggests that rehearsing and practice impacts performance more than environmental noise levels.

Association of Frailty With Post-Operative Outcomes of Older Adults Undergoing Elective Ostomy Reversal.

BACKGROUND: Ostomy reversal is a common surgical procedure; however, it is not without associated risks. Patient selection for this elective procedure is therefore critically important. Elderly patients represent a growing population and a substantial proportion of patients that present for evaluation after ostomy creation due to the most common etiologies. This study aims to assess the impact of frailty on the outcomes of ostomy reversal among older adults. METHODS: Patients ≥65 years who underwent ostomy reversal from 2015 to 2019 were identified in the NSQIP database. Frailty was calculated using the 5-item Modified Frailty Index (MFI). Multivariate regression was performed to evaluate the association of frailty with post-operative 30-day mortality, 30-day serious complications, discharge to a facility, and 30-day readmission. RESULTS: A total of 13,053 patients were included, of which 18.7% were frail (MFI ≥ 2). Patients who underwent colostomy reversal had higher rates of serious complications (P < .0001) and discharge to facility (P < .0001) compared to other reversals. In multivariate analysis, frailty was associated with increased odds of serious complications (OR 1.52, 95% CI 1.31-1.77), discharge to facility (OR 2.14, 95% CI 1.79-2.57), and readmission (OR 1.23, 95% CI 1.04-1.46), but not mortality. Frail patients had predicted probabilities 1.4 times higher for serious complications and 1.7-2.2 times greater for discharge to facility than non-frail patients. CONCLUSIONS: Among older adults undergoing elective ostomy reversal, frailty is independently associated with increased odds of 30-day serious complications, discharge to facility, and 30-day readmission. As a potentially modifiable risk factor, identification of frailty offers the opportunity for shared decision-making and prehabilitation.

Current use of the National Surgical Quality Improvement Program surgical risk calculator in academic surgery: a mixed-methods study.

Background: This study aims to quantitatively assess use of the NSQIP surgical risk calculator (NSRC) in contemporary surgical practice and to identify barriers to use and potential interventions that might increase use. Materials and methods: We performed a cross-sectional study of surgeons at seven institutions. The primary outcomes were self-reported application of the calculator in general clinical practice and specific clinical scenarios as well as reported barriers to use. Results: In our sample of 99 surgeons (49.7% response rate), 73.7% reported use of the NSRC in the past month. Approximately half (51.9%) of respondents reported infrequent NSRC use (<20% of preoperative discussions), while 14.3% used it in ≥40% of preoperative assessments. Reported use was higher in nonelective cases (30.2% vs 11.1%) and in patients who were ≥65 years old (37.1% vs 13.0%), functionally dependent (41.2% vs 6.6%), or with surrogate consent (39.9% vs 20.4%). NSRC use was not associated with training status or years in practice. Respondents identified a lack of influence on the decision to pursue surgery as well as concerns regarding the calculator's accuracy as barriers to use. Surgeons suggested improving integration to workflow and better education as strategies to increase NSRC use. Conclusions: Many surgeons reported use of the NSRC, but few used it frequently. Surgeons reported more frequent use in nonelective cases and frail patients, suggesting the calculator is of greater utility for high-risk patients. Surgeons raised concerns about perceived accuracy and suggested additional education as well as integration of the calculator into the electronic health record.

The Association of Frailty With Outcomes for Older Adults Undergoing Appendectomy.

BACKGROUND: Frailty is a potential modifiable predictor of surgical outcomes in older adults. The impact of frailty following appendectomy, a common urgent operation, is unknown for older adults. The study aim was to assess if frailty is associated with worse perioperative outcomes after appendectomy in older adults. METHODS: We used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database from 2016 to 2018 and identified patients 65 and older who underwent appendectomy for acute appendicitis. We identified frailty as a Modified Frailty Index (MFI) score ≥2. Multivariate logistic regression was used to assess the association of frailty with 30-day mortality, serious complications, readmission, and discharge to facility. RESULTS: Five thousand seven hundred twenty-eight older adults underwent appendectomy, of which 29.1% were 75 or older, 53.3% female, 74.9% non-Hispanic White, and 17.1% frail. Frail patients experienced worse outcomes: mortality (frail: 1.0% vs non-frail: .3%, P = .001), serious complications (14.2% vs 8.0%, P = <.0001), and discharge to facility (9.3% vs 2.3%, P < .0001). On multivariate logistic regression, frailty was associated with increased mortality (odds ratio [OR] 3.34; 95% confidence interval [CI] 1.28-8.66), serious complications (OR 1.51; 95% CI: 1.17-1.93), and discharge to facility (OR 2.80; 95% CI: 2.00-3.93). Frailty was not significantly associated with readmission (P = .180). CONCLUSIONS: Frailty is associated with worse postoperative outcomes following appendectomy in older adults. As frailty is potentially modifiable, it should be routinely assessed and utilized in perioperative optimization and counseling, especially with respect to patient-centered outcomes.

Observed child restraint misuse in a large, urban community: Results from three years of inspection events.

PROBLEM: Child restraints (CRs) are vital for optimizing child passenger safety and reducing the risk of pediatric injury and fatality in motor vehicle crashes. However, most CRs are installed improperly. METHODS: This present study was an assessment of observed instances of CR misuse. Participants were recruited through advertisements for CR inspection events in Los Angeles County, California. Child Passenger Safety Technicians collected information about each child passenger, vehicle, and aspects of CR selection and installation. RESULTS: Of 693 CRs installed upon arrival, only 3.8% were used with no instances of misuse. The most common misuses were inappropriate use of the top tether and failure to secure the seatbelt in locked mode. CONCLUSIONS: The majority of observed CRs were installed with instances of misuse. CRs in newer vehicles were less likely to be installed in front of airbags and more likely to have the seatbelt routed inappropriately compared to those in older vehicles. Older children were more likely to be prematurely restrained in the front vehicle seat. PRACTICAL APPLICATIONS: The majority of CRs are installed improperly. We identified specific instances of CR misuse that are common in a large, urban community and present recommendations to improve child passenger safety practices and education.

Assessment of parental knowledge and attitudes toward pediatric sports-related concussions.

BACKGROUND: Parents of young athletes play a major role in the identification and management of sports-related concussions. However, they are often unaware of the consequences of concussions and recommended management techniques. HYPOTHESIS: This study quantitatively assessed parental understanding of concussions to identify specific populations in need of additional education. We predicted that parents with increased education and prior sports- and concussion-related experience would have more knowledge and safer attitudes toward concussions. STUDY DESIGN: Cross-sectional survey. LEVEL OF EVIDENCE: Level 5. METHODS: Participants were parents of children brought to a pediatric hospital and 4 satellite clinics for evaluation of orthopaedic injuries. Participants completed a validated questionnaire that assessed knowledge of concussion symptoms, attitudes regarding diagnosis and return-to-play guidelines, and previous sports- and concussion-related experience. RESULTS: Over 8 months, 214 parents completed surveys. Participants scored an average of 18.4 (possible, 0-25) on the Concussion Knowledge Index and 63.1 (possible, 15-75) on the Concussion Attitude Index. Attitudes were safest among white women, and knowledge increased with income and education levels. Previous sports experience did not affect knowledge or attitudes, but parents who reported experiencing an undiagnosed concussion had significantly better concussion knowledge than those who did not. CONCLUSION: Parents with low income and education levels may benefit from additional concussion-related education. CLINICAL RELEVANCE: There exist many opportunities for improvement in parental knowledge and attitudes about pediatric sports-related concussions. Ongoing efforts to understand parental knowledge of concussions will inform the development of a strategic and tailored approach to the prevention and management of pediatric concussions.

Assessing medical care availability for student athletes of a large urban high school district.

BACKGROUND: The need for medical care for student athletes is mounting, as participation in high school athletics is continuing to rise. This study assessed medical care available to high school student athletes in a large, urban school district in California that has not been studied since 2002. By surveying athletic directors and coaches, we expected to find inadequate availability of medical care in the studied district and predicted that care would be more widely available for student athletes at larger high schools. METHODS: We developed and validated a questionnaire assessing practice and game coverage, emergency preparedness, treatment, and injury prevention measures. The survey was administered to athletic directors and coaches at a school district athletic directors' meeting. RESULTS: Forty-three (57%) of 75 distributed surveys were completed. We found that 70% of schools did not staff a healthcare provider for practices, 28% did not staff home games, and 30% did not staff away games, for any sports. We found no significant differences between school sizes with respect to physician referrals after a student was injured, provision of health education, or implementation of emergency action plans. CONCLUSIONS: Although these data do not support our hypothesis of larger schools providing better medical care, it suggests that there are multiple areas of inadequate healthcare regardless of school size. We identified numerous gaps; thus, future work will examine the impact of these gaps.

The extended-short nail system, a novel concept in the management of proximal femur fractures.

In light of recent health care reform and the aging US Medicare population, it is becoming increasingly important for orthopedic surgeons to use effective and efficient strategies for hip fracture surgery. The Extended-Short Nail System (ES nail) is a US Food and Drug Administration-approved titanium nail which is locked at the same location as the locking hole of a short intramedullary (IM) nail. The ES nail takes advantage of an "extended-short" hybrid design combining the mechanical characteristics of a long IM nail with the surgical ease of use offered with a short IM nail.

Bilateral femoral neck stress fractures in a fire academy student.

Unilateral femoral neck stress fractures are well documented in active patients; however, the risk of a subsequent contralateral stress fracture remains unknown in patients who continue to be active. This article describes a 24-year-old male fire academy student who sustained a left femoral neck stress fracture, followed approximately 11 months later by a right femoral neck stress fracture, both of which went on to completely displace. A review of the index radiographs of each hip from outside institutions revealed femoral neck stress fractures that went undiagnosed until they displaced. The patient was referred to our institution and underwent closed reduction and internal fixation using cannulated screws in both cases. A full endocrine evaluation was performed in the following weeks and proved unremarkable. Although it is difficult to extrapolate the results from 1 patient beyond the case studied, there is cause for concern in patients who remain active following femoral neck stress fractures. Our case highlights the significance of obtaining a complete and thorough medical history on physical examination and appropriately counseling patients regarding activity level. Until further research explores this possible relationship, physicians evaluating patients with a history of a stress fracture are encouraged to be vigilant of subsequent contralateral fractures and educate patients of this potentially avoidable injury.
