Wound Classification Score Discordance in Pediatric Operations - A Quality Improvement Study.

BACKGROUND: Wound classification scores are used to categorize the risk of postoperative infections. It was noted at our academic institution that wound classifications were often inaccurately recorded in the electronic health record. We thus instituted a quality improvement program, hypothesizing that this would improve charting accuracy. METHODS: On June 1, 2019, we posted the wound classifications in each pediatric operating room (OR), provided OR nurses with teaching, and began including the classification in the postoperative surgeon debriefing. We performed a retrospective chart review of all general pediatric operations from June 19 to December 19 to compare classifications recorded in the electronic health record to the "correct" classification determined by manual review of operating reports. These data were compared with a similar chart review from 2018. To compare the efficacy of nursing versus physician focused changes, we compared our appendectomy data with a nearby community institution where the same group of surgeons practice. Pearson's Chi-squared test was used to report the significance of the differences observed in the concordance proportion, with 95% confidence intervals calculated using the Clopper-Pearson procedure. RESULTS: Overall, 444 pre- and 179 postpractice change charts were reviewed. There were no significant differences pre or postpractice change. At the community institution, we noted a significant improvement in charting accuracy for appendectomies from 3.33% to 44.83%. DISCUSSION: Despite implementing nursing and physician focused quality improvement practices, there was not a significant improvement in charting accuracy at the academic institution. However, we did note an improvement at the community facility where our pediatric surgeons also practice. We thus suspect that our nursing focused changes may have been inadequate. Future efforts will focus on providing intensive and sustained OR nurse training to help improve the wound classification charting accuracy.

A Typology of Civilians Shot and Killed by US Police: a Latent Class Analysis of Firearm Legal Intervention Homicide in the 2014-2015 National Violent Death Reporting System.

Approximately 1000 people are killed by police acting in the line of duty each year. Historically, research on these deaths, known as legal intervention homicides (LIH), has been limited by data that is either contextually rich but narrow in scope and not readily available to the public (e.g., police department reports from a single city), or detail-poor but geographically broad, large, and readily available (and maintained by federal agencies) (e.g., vital statistics and supplemental homicide reports). Over the past 5 years, however, researchers have turned to the National Violent Death Reporting System (NVDRS), which captures nearly all lethal police shootings in participating states while providing detailed incident and victim information. The current study extends prior work on police-involved lethal shootings in three important ways. First, we use latent class analysis to construct a data-driven, exhaustive, mutually exclusive typology of these events, using NVDRS data 2014-2015. Second, rather than fitting some, but not all cases into predefined sub-types, every case is assigned membership to a particular emergent class. Third, we use a validated case identification process in NVDRS to identify incidents of lethal police-involved shootings. Seven classes emerge. Classes differ across important incident and victim characteristics such as the event that brought the victim and law enforcement together, the highest level of force used by the victim against law enforcement, and the kind of weapon, if any, used by the victim during the incident. Demographic variables do not distribute uniformly across classes (e.g., the latent class in which the victim appeared to pose minimal threat to law enforcement was the only class in which the plurality of victims was a non-white race). Our approach to generating these typologies illustrates how data-driven techniques can complement subjective classification schemes and lay the groundwork for analogous analyses using police encounter data that include fatal and non-fatal outcomes.

Differences Between New and Long-Standing US Gun Owners: Results From a National Survey.

OBJECTIVES: To quantify the proportion of current US gun owners who are new to owning firearms and compare new versus long-standing gun owners with respect to their firearms and firearm-related behaviors. METHODS: We performed a cross-sectional analysis of a nationally representative probability-based online survey conducted in 2015 in the United States. We defined new gun owners as current firearm owners who acquired all of their firearms within the past 5 years, but who lived in a home without a gun at some time over the past 5 years. We defined long-standing firearm owners as all other current gun owners. RESULTS: New gun owners represented 10% of all current US adult gun owners. In addition to being younger than long-standing gun owners, new gun owners were more likely to be liberal, own fewer guns, own handguns, own guns only for protection, and store guns in a safe manner. CONCLUSIONS: Gun ownership is dynamic, with approximately 1 million Americans becoming new gun owners each year. Public Health Implications. Clinical guidelines should be updated to explicitly endorse re-evaluating household firearm status at regular intervals.

Variation in pediatric cervical spine imaging across trauma centers-A cause for concern?

BACKGROUND: Traumatic pediatric cervical spine injury can be challenging to diagnose, and the clinical algorithms meant to aid physicians differ from adult trauma protocols. Despite the existence of standardized guidelines, imaging decisions may vary according to physician education, subjective assessment, and experience with pediatric trauma patients. Our study investigates the rates of pediatric posttraumatic cervical spine imaging across trauma centers, hypothesizing that more specialized centers will have lower rates of advanced cervical spine imaging. METHODS: The 2015 to 2016 Trauma Quality Improvement Program database was reviewed for patients younger than 18 years- to assess rates of cervical spine imaging on presentation across different trauma centers. Propensity stratification logistic regression was performed controlling for patient- and center-specific variables. p Values less than 0.05 were considered significant. RESULTS: Of 110,769 pediatric trauma patients, 35.2% were female, and the average age was 9.6 years. Overall, 3.6% had cervical spine computed tomography (CT) and less than 1% had cervical spine MRI or X-ray. Compared with all others, Level I trauma centers were significantly less likely to use cervical spine CT for the initial evaluation of younger (≤14 years) but not older trauma patients (adjusted odds ratio [AOR], 0.89; 95% confidence interval [CI], 0.80-0.99; AOR, 0.97; 95% CI, 0.87-1.09); Level I centers had higher odds of cervical spine MRI use, but only for patients 14 years or younger (AOR, 1.63; 95% CI, 1.09-2.44). Pediatric-designated trauma centers had significantly lower odds of cervical spine CT (≤14 years: AOR, 0.70; 95% CI, 0.63-0.78; >14 years: AOR, 0.67; 95% CI, 0.67-0.75) and higher odds of cervical spine X-ray (≤14 years: AOR, 4.75; 95% CI, 3.55-6.36; >14 years: AOR, 4.50; 95% CI, 2.72-7.45) for all ages, but higher odds of cervical spine MRI for younger patients only (≤14 years: AOR, 2.10; 95% CI, 1.38-3.21). CONCLUSION: Level I and pediatric designations were associated with lower rates of cervical spine CT. Pediatric centers were also more likely to use cervical spine X-ray. This variability of imaging use further supports the need to disseminate and educate providers on pediatric-specific cervical spine evaluation guidelines. LEVEL OF EVIDENCE: Prognostic and epidemiological, level III.
