American firearm homicides: The impact of your neighbors.

BACKGROUND: Restrictive firearm legislation has correlated with decreased overall firearm fatality rates, but not with firearm-related homicide or firearm mortality among Black Americans. We hypothesized that firearm trafficking from states with less restrictive firearm legislation to neighboring states with more restrictive firearm legislation increases firearm homicide rates in those restrictive states. METHODS: For years 2011-2015, state firearm legislation Brady Campaign to Prevent Gun Violence scorecards were analyzed in relation to firearms traced by the Bureau of Alcohol, Tobacco, and Firearms and Center for Disease Control and Prevention firearm mortality rates. States were ranked by Brady score and arranged by quintile to establish the Standardized Brady Score. The effect of less-restrictive neighboring states on the 10 most-restrictive firearm legislation states was modeled by averaging the 10 most-restrictive states with their bordering states to create a Border Adjustment Score. Firearm fatality rates were calculated for each quintile and Poisson regression models were created for each score and outcome. Model fit was compared using Akaike Information Criterion (AIC). RESULTS: There were 169,396 firearm fatalities including 57,885 firearm homicides. Comparing top and bottom quintile firearm legislation states, 65% vs. 44% of firearms traced by the Bureau of Alcohol, Tobacco, Firearms and Explosives originated in other states respectively. The Border Adjustment Score generated a more linear relationship than the Standardized Brady Score for all firearm fatality categories as firearm legislation scores decreased. The Border Adjustment Score minimized the AIC with respect to the Standardized Brady Score for black (AIC, 4443 vs. 4680) and white firearm homicide rates (3243 vs. 4319), indicating improved model fit after adjustment for neighboring state firearm legislation. CONCLUSION: Our results suggest that firearm movement across states plays an important role in firearm homicides. Accounting for firearm legislation in both individual and neighboring states may improve our understanding of the relationship between firearm legislation and homicide. LEVEL OF EVIDENCE: Prognostic and epidemiological study, level IV.

Short simulation training improves objective skills in established advanced practitioners managing emergencies on the ward and surgical intensive care unit.

BACKGROUND: Several studies evaluating simulation training in intensive care unit (ICU) physicians have demonstrated improvement in leadership and management skills. No study to date has evaluated whether such training is useful in established ICU advanced practitioners (APs). We hypothesized that human patient simulator-based training would improve surgical ICU APs' skills at managing medical crises. METHODS: After institutional review board approval, 12 APs completed ½ day of simulation training on the SimMan, Laerdal system. Each subject participated in five scenarios, first as team leader (pretraining scenario), then as observer for three scenarios, and finally, again as team leader (posttraining). Faculty teaching accompanied each scenario and preceded a debriefing session with video replay. Three experts scored emergency care skills (Airway-Breathing-Circulation [ABCs] sequence, recognition of shock, pneumothorax, etc.) and teamwork leadership/interpersonal skills. A multiple choice question examination and training effectiveness questionnaire were completed before and after training. Fellows underwent the same curriculum and served to validate the study. Pre- and postscores were compared using the Wilcoxon signed rank test with two-tailed significance of 0.05. RESULTS: Improvement was seen in participants' scores combining all parameters (73% ± 13% vs. 80% ± 11%, p = 0.018). AP leadership/interpersonal skills (+12%), multiple choice question examination (+4%), and training effectiveness questionnaire (+6%) scores improved significantly (p < 0.05). Fellows teamwork leadership/interpersonal skills scores were higher than APs (p < 0.001) but training brought AP scores to fellow levels. Interrater reliability was high (r = 0.77, 95% confidence interval 0.71-0.82; p < 0.001). CONCLUSIONS: Human patient simulator training in established surgical ICU APs improves leadership, teamwork, and self-confidence skills in managing medical emergencies. Such a validated curriculum may be useful as an AP continuing education resource.

[Vacuum pack technique--a good method for temporal abdominal closure]. / Vakuumpakking--en god metode for midlertidig bukveggslukking.

UNLABELLED: Abdominal compartment syndrome(ACS) is a clinical entity characterised by increased intraabdominal pressure leading to multiple organ failure, fatal if left untreated. The treatment of abdominal compartment syndrome is surgical decompression with a temporary abdominal wall substitute. To avoid the development of abdominal compartment syndrome, temporary abdominal closure (TAC) should be considered after celiotomy for trauma. A new method for TAC was introduced at Ullevaal University Hospital in 2002, the "vac pac". METHOD: The "vac pac" technique is described and the patients treated with "vac pac" during the first year after introduction are presented. RESULTS: Five patients were treated using the "vac pac". One patient had acute pancreatitis and developed abdominal compartment syndrome. The other patients were severely injured and the indication for TAC was abdominal compartment syndrome in one patient, intestinal oedema in another, and damage control surgery with packing in two patients. Delayed primary closure was achieved within five days in all our patients. There were no fatalities and no complications related to the use of "vac pac" were registered. CONCLUSION: The "vac pac" technique seems to be a good method for TAC.
