ObjectiveThe aim of this study was to understand variation in intraoperative and postoperative utilization for common general surgery procedures.Summary background dataReducing surgical costs is paramount to the viability of hospitals.MethodsRetrospective analysis of electronic health record data for 7762 operations from 2 health systems. Adult patients undergoing laparoscopic cholecystectomy, appendectomy, and inguinal/femoral hernia repair between November 1, 2013 and November 30, 2017 were reviewed for 3 utilization measures: intraoperative disposable supply costs, procedure time, and postoperative length of stay (LOS). Crossed hierarchical regression models were fit to understand case-mixed adjusted variation in utilization across surgeons and locations and to rank surgeons.ResultsThe number of surgeons performing each type of operation ranged from 20 to 63. The variation explained by surgeons ranged from 8.9% to 38.2% for supply costs, from 15.1% to 54.6% for procedure time, and from 1.3% to 7.0% for postoperative LOS. The variation explained by location ranged from 12.1% to 26.3% for supply costs, from 0.2% to 2.5% for procedure time, and from 0.0% to 31.8% for postoperative LOS. There was a positive correlation (ρ = 0.49, P = 0.03) between surgeons' higher supply costs and longer procedure times for hernia repair, but there was no correlation between other utilization measures for hernia repair and no correlation between any of the utilization measures for laparoscopic appendectomy or cholecystectomy.ConclusionsSurgeons are significant drivers of variation in surgical supply costs and procedure time, but much less so for postoperative LOS. Intraoperative and postoperative utilization profiles can be generated for individual surgeons and may be an important tool for reducing surgical costs.

Background Firearm violence results in the death of thousands of children in the US annually. The effects of firearm legislation on gun violence are published but widely contested. Materials and Methods The Kid's Inpatient Database from 2000 to 2009 were queried to capture hospitalizations of children diagnosed with a firearm-related injury. Cases were categorized into five levels of firearm legislation strictness by Brady State Scorecard. Trends of injuries were explored in terms of legislative strength, age, and race. Results 27,566 children analyzed in the study. Most were adolescents aged 15–19 (87.3%), male (89.7%), and black (53.7%). The proportion of accidental injuries increased relative to state law leniency (R2 = 0.90), with highest percentage in lenient states (33.2%) compared to strict (16.7%). The proportion of suicide attempts were higher in states with lenient laws (4.4%) compared to strict (1.3%). Accidents were inversely related to age (59.3% in ages 0–4 compared to 22.0% in adolescents), while assaults were positively related to age (31.6% in ages 0–4 compared to 66.6% in adolescents). Whites were most likely to present with accidental injuries (44.6%), and Blacks and Hispanics with assaults (68.2% and 75.6%). Race (p = 0.009), age (p Conclusions Firearm-related injuries types in hospitalized children are associated with age, race, and state level legislation. Accidents are most prevalent in young children, Whites, and states with lenient gun laws, while suicide attempts are more common in adolescents, Whites, and states with lenient gun laws. Suicide attempts are also associated with the greatest odds of in-hospital mortality. To address firearm violence, consideration should be given to legislation that promote safe gun storage behaviors and restrict firearm accessibility to children.

β-Adrenergic receptor blockers (BBs) administered after trauma blunt the cascade of immune and inflammatory changes associated with injury. BBs are associated with improved outcomes after traumatic brain injury (TBI). Propranolol may be an ideal BB because of its nonselective inhibition and ability to cross the blood-brain barrier. We determined if early administration of propranolol after TBI is associated with lower mortality.All adults (age ≥ 18 years) with moderate-to-severe TBI (head Abbreviated Injury Scale [AIS] score, 3-5) requiring intensive care unit (ICU) admission at a Level I trauma center from January 1, 2013, to May 31, 2015, were prospectively entered into a database. Administration of early propranolol was dosed within 24 hours of admission at 1 mg intravenous every 6 hours. Patients who received early propranolol after TBI (EPAT) were compared with those who did not (non-EPAT). Data including demographics, hospital length of stay (LOS), ICU LOS, and mortality were collected.Over 29 months, 440 patients with moderate-to-severe TBI met inclusion criteria. Early propranolol was administered to 25% (109 of 440) of the patients. The EPAT cohort was younger (49.6 years vs. 60.4 years, p0.001), had lower Glasgow Coma Scale (GCS) score (11.7 vs. 12.4, p = 0.003), had lower head AIS score (3.6 vs. 3.9, p = 0.001), had higher admission heart rate (95.8 beats/min vs. 88.4 beats/min, p = 0.002), and required more days on the ventilator (5.9 days vs. 2.6 days, p0.001). Similarities were noted in sex, Injury Severity Score (ISS), admission systolic blood pressure, hospital LOS, ICU LOS, and mortality rate. Multivariate regression showed that EPAT was independently associated with lower mortality (adjusted odds ratio, 0.25; p = 0.012).After adjusting for predictors of mortality, early administration of propranolol after TBI was associated with improved survival. Future studies are needed to identify additional benefits and optimal dosing regimens.Therapeutic study, level IV.

BACKGROUND The obese state has been linked to several immune-mediated conditions. Our objective was to examine the association of body mass index (BMI) with the diagnosis of heparin-induced thrombocytopenia (HIT). METHODS Prospectively collected data on patients in the surgical and cardiac intensive care unit suspected of having HIT between January 2007 and August 2014 were analyzed. Patients were categorized into five discrete BMI (kg/m) groups and compared. Data collected included Warkentin 4-T scores, antiplatelet factor 4 (anti-PF4OD) values, serotonin release assay values, and thromboembolic diseases. HIT positivity was defined as serotonin release assay value greater than 20%. RESULTS Of 304 patients meeting inclusion criteria, mean (SD) age was 62.1 (16.5) years, 59% were male, and mean (SD) BMI was 27 (6) kg/m. Thirty-six (12%) were positive for HIT. Incidence of HIT increased progressively with BMI (0%, 8%, 11%, 19%, 36%; p < 0.001). Compared with patients with normal BMI, patients with a BMI of 30 kg/m to 39.9 kg/m had a 200% increase in the odds for HIT (odds ratio [OR], 2.94; 95% confidence interval [CI], 1.20-7.54; p = 0.019), while patients with a BMI of 40 kg/m or greater had a 600% increase (OR, 6.98; 95% CI, 1.59-28.2; p = 0.012). After regression analysis, BMI remained an independent predictor of the development of HIT (adjusted OR per kg/m, 1.08; 95% CI, 1.02-1.14; p = 0.010). Anti-PF4OD values greater than or equal to 2.0 also increased with BMI (p < 0.001). In-hospital mortality increased significantly with BMI above normal (p = 0.026). Warkentin 4-T scores, deep venous thrombosis, pulmonary embolism, and stroke incidence did not correlate with changes in BMI. CONCLUSION Increasing BMI seems to be strongly associated with increased rates of HIT in intensive care unit patients. Obesity is an important new clinical variable for estimating the pretest probability of HIT, and patient "thickness" could be considered a fifth "T" of the 4-T scoring system. Additional biochemical work is indicated to decipher the role of obesity in this immune-mediated condition. LEVEL OF EVIDENCE Prognostic/epidemiologic study, level III.

Clinical studies suggest an association between FI and adverse outcomes in patients with traumatic brain injury. Military tactical emergency casualty care recomm

The Joint Commission on the Accreditation of Healthcare Organizations reports that communication breakdowns are responsible for 85% of sentinel events in hospitals. Patients in surgical ICUs are the most vulnerable to communication errors. Fellows and residents are an integral part of the surgical ICU team, but little is known about resident-fellow communication and its impact on surgical ICU patient outcomes. The objective of this study is to describe resident-fellow patient care communication patterns in the surgical ICU and correlate established communication patterns with short-term outcomes.A prospective observational trial was conducted for 136 consecutive surgical ICU days. We evaluated resident-fellow communication of four cardiorespiratory events: hypotension, new arrhythmias, tachypnea, and desaturation. We prospectively defined three short-term outcomes: improved, not improved, and worse. An intervention was attempted to improve communication.Three hundred twelve events were collected (166 observational and 146 interventional). PGY3 residents covered approximately 60% of days in both phases. PGY3 residents were responsible for 73% of communication errors in the observational phase and 59% of communication errors in the interventional phase. Communication errors were more likely in the late shift (p0.0001). The late shift was responsible for 77% of all communication errors. Communication errors resulted in worse short-term outcomes for cardiorespiratory events (p0.0002). Effective communication was a significant predictor of improved short-term outcomes (p0.0003). The intervention decreased communication errors in the late shift by 10% (p0.052).Communication errors occurred more frequently during the late shift. These communication errors were associated with worsened short-term outcomes. Improved communication in the surgical ICU is a fruitful target to improve clinical outcomes.
