Multicenter Study Comparative StudyImpact of hormonal protection in blunt and penetrating trauma: a retrospective analysis of the National Trauma Data Bank.
Over the last decade, gender and age-related hormonal status of trauma patients have been increasingly recognized as outcome factors. In the present study, we examine a large cohort of trauma patients to better appraise the effects of gender and age on patient outcome after blunt and penetrating trauma. We hypothesize that adult females are at lower risk for complications and mortality relative to adult males after both blunt and penetrating trauma. ⋯ Adult females demonstrated a survival advantage over adult males (OR, 0.69; 95% CI, 0.67 to 0.71). Adult females with ISS less than 15 demonstrated a distinct survival advantage compared with adult males after both blunt and penetrating trauma. These results warrant further investigation into the role of sex hormones in trauma.

Multicenter Study Comparative StudyCost analysis of laparoscopic versus open colectomy in patients with colon cancer: results from a large nationwide population database.
Laparoscopic colectomy (LC) is a safe and reliable option for patients with colon cancer. This study examined factors associated with LC use and cost differences between LC and open colectomy (OC). Using the Cost & Utilization Project National Inpatient Sample database (2008), patients with colon cancer undergoing elective LC or OC were selected. ⋯ LC is a less expensive but less popular surgical option for colon cancer. Stage, race, Charlson score, teaching status, location, and hospital size influence the use of a laparoscopic approach. LC is associated with fewer complications and decreased mortality which contribute to its lower cost as compared with OC.

Multicenter Study Comparative StudyBurn-center quality improvement: are burn outcomes dependent on admitting facilities and is there a volume-outcome "sweet-spot"?
Risk factors of mortality in burn patients such as inhalation injury, patient age, and percent of total body surface area (%TBSA) burned have been identified in previous publications. However, little is known about the variability of mortality outcomes between burn centers and whether the admitting facilities or facility volumes can be recognized as predictors of mortality. De-identified data from 87,665 acute burn observations obtained from the National Burn Repository between 2003 and 2007 were used to estimate a multivariable logistic regression model that could predict patient mortality with reference to the admitting burn facility/facility volume, adjusted for differences in age, inhalation injury, %TBSA burned, and an additional factor, percent full thickness burn (%FTB). ⋯ The treatment/admitting facility was found to be an independent mortality predictor, with certain hospitals having increased odds of death and others showing a protective effect (decreased odds ratio). Hospitals with high burn volumes had the highest risk of mortality. Mortality outcomes of patients with similar risk factors (%TBSA burned, inhalation injury, age, and %FTB) are significantly affected by the treating facility and their admission volumes.

Randomized Controlled Trial Multicenter StudyA double-blind, randomized, active-controlled study for post-hemorrhoidectomy pain management with liposome bupivacaine, a novel local analgesic formulation.
This randomized, active-controlled study evaluated the extent and duration of analgesia after administration of liposome bupivacaine (LB), a novel formulation of bupivacaine, compared with bupivacaine HCl given via local infiltration in excisional hemorrhoidectomy. One hundred patients were randomly assigned to receive a single dose of bupivacaine HCl 75 mg (0.25% with 1:200,000 epinephrine) or LB 66, 199, or 266 mg upon completion of hemorrhoidectomy. Postoperative pain intensity was assessed using a numeric rating scale at rest to calculate a cumulative pain score (area under the curve). ⋯ Median time to first opioid use was 19 hours for LB 266 mg versus 8 hours for bupivacaine HCl (P = 0.005). Incidence of opioid-related adverse events was 4 per cent for LB 266 mg compared with 35 per cent for bupivacaine HCl (P = 0.007). Local infiltration with LB resulted in significantly reduced postsurgical pain compared with bupivacaine HCl in patients after hemorrhoidectomy surgery.
