Randomized Controlled TrialRoutine Use of Prophylactic Antibiotics during Laparoscopic Cholecystectomy Does Not Reduce the Risk of Surgical Site Infections.
Laparoscopic cholecystectomy (LC) is the gold standard for the treatment of symptomatic gallbladder stones. As infections are rare in uncomplicated LC, it is widely accepted that prophylactic antibiotics need not be administered, and guidelines do not support routine antibiotic prophylaxis during elective LC. However, routine antibiotic prophylaxis for elective LC is still popular in many clinical settings. We investigated this situation in our department. ⋯ Surgical site infection is rare after LC, and antibiotic prophylaxis does not appear to affect the outcome significantly. Moreover, factors such as positive bile cultures, history of biliary attack, ASA score, diabetes, obesity, and smoking do not have any effect on SSI development. Thus, we conclude that antibiotic prophylaxis is not needed for elective LC.

Do Patients with Pre-Existing Psychiatric Illness Have an Increased Risk of Infection after Injury?
Trauma remains a leading cause of death and long term-morbidity. We have shown that patients who sustain traumatic injuries are at increased risk for the development of infectious complications. Psychiatric illnesses (PIs) are also noted to occur frequently among the general population. The presence of a PI has been shown to be a risk factor for the development of infections. Despite the prevalence of both traumatic injuries and psychiatric diseases, there are little data relating the impact of PI on the outcome of patients with trauma. We hypothesize that the presence of a PI will be associated with an increased risk of an infection developing after injury. ⋯ Of the 11,147 admitted trauma patients, 14.5% had a pre-injury PI diagnosis. The PI patients were older (61.5 ± 0.5 vs. 54.3; p < 0.001), more often female (56% vs. 39.1%; p < 0.001), and had no difference in blunt mechanism rates (88.4% vs. 89.9%; p = 0.06) or median ISS (9 vs. 9; p = 0.06). There was no difference between PI and non-PI patients in pre-injury diabetes mellitus (13.4% vs. 12.7%; p = 0.4), steroid use (2.5% vs. 1.9%; p = 0.1), but patients with PI were more likely to be obese (15.7% vs. 13.6%; p = 0.03). Patients with PI were more likely to have an infection develop (10.4% vs. 7.5%; p < 0.001). The most common infection in both groups was UTI (6.9% vs. 4.2%; p < 0.001). Compared with non-PI patients, adjusting for age, gender, ISS, diabetes mellitus, and obesity, patients with PI were more likely to have an infection develop (odds ratio 1.3, 95% confidence interval = 1.1-1.5) Conclusions: Patients with an underlying PI are at increased risk of having a UTI after traumatic injury. This study identifies a previously unknown independent risk factor for UTIs in patients with trauma. This stresses the need for increased awareness and attention to this vulnerable population.

Current Pneumonia Surveillance Methodology: Similar Underestimation in Trauma and Surgical Patients in the Intensive Care Unit.
In 2013, the Centers for Disease Control and Prevention (CDC) developed new surveillance definitions for ventilator-associated events (VAE), leading to concerns that hospitals may be underreporting the true incidence of ventilator-associated pneumonias (VAPs). We sought to compare rates of clinically diagnosed VAP with CDC defined possible VAPs (PVAPs) in patients with a VAE in the surgical/trauma intensive care unit (STICU). ⋯ The new CDC definition for PVAP grossly underestimates the clinical diagnosis of VAP and reports less than a third of the patients treated for VAP. Reporting differences were similar for trauma and surgical patients.

Survival from Traumatic Injury Does Not End at Hospital Discharge: Hospital-Acquired Infections Increase Post-Discharge Mortality.
Hospital-acquired infections (HAI) in trauma patients increase inpatient morbidity and mortality. However, their impact on long-term mortality is not well understood. ⋯ Trauma patients with HAP have higher mortality after hospital discharge. Prevention strategies for HAP including pulmonary toilet, early mobility, pain control, and early extubation must be a priority. Unfortunately, patients who develop pneumonia may have a decreased reserve, or ability to recover from their traumatic injuries and HAI. Further characterization of HAP and its subsequent treatment strategies are needed.
