BACKGROUND Bathing intensive care unit (ICU) patients with 2% chlorhexidine gluconate (CHG)-impregnated cloths decreases the risk of healthcare-associated bacteremia and multidrug-resistant organism transmission. Hospitals employ different methods of CHG bathing, and few studies have evaluated whether those methods yield comparable results. OBJECTIVE To determine whether 3 different CHG skin cleansing methods yield similar residual CHG concentrations and bacterial densities on skin. DESIGN Prospective, randomized 2-center study with blinded assessment. PARTICIPANTS AND SETTING Healthcare personnel in surgical ICUs at 2 tertiary-care teaching hospitals in Chicago, Illinois, and Boston, Massachusetts, from July 2015 to January 2016. INTERVENTION Cleansing skin of one forearm with no-rinse 2% CHG-impregnated polyester cloth (method A) versus 4% CHG liquid cleansing with rinsing on the contralateral arm, applied with either non-antiseptic-impregnated cellulose/polyester cloth (method B) or cotton washcloth dampened with sterile water (method C). RESULTS In total, 63 participants (126 forearms) received method A on 1 forearm (n=63). On the contralateral forearm, 33 participants received method B and 30 participants received method C. Immediately and 6 hours after cleansing, method A yielded the highest residual CHG concentrations (2500 µg/mL and 1250 µg/mL, respectively) and lowest bacterial densities compared to methods B or C (P<.001). CONCLUSION In healthy volunteers, cleansing with 2% CHG-impregnated cloths yielded higher residual CHG concentrations and lower bacterial densities than cleansing with 4% CHG liquid applied with either of 2 different cloth types and followed by rinsing. The relevance of these differences to clinical outcomes remains to be determined. Infect Control Hosp Epidemiol 2018;39:405-411.

BACKGROUND:The Eastern Association for the Surgery of Trauma (EAST) recommends that clinicians consider limiting further aggressive treatment in geriatric patients with severe traumatic brain injury (TBI) who do not improve in 72 hours (nonresponders) owing to their poor prognosis. However, little is known about how these guidelines are followed in practice. This study compared mortality and patient care among geriatric patients with severe TBI classified as "responders" and "nonresponders" 72 hours after injury. METHODS:Retrospective review of patients 65 years or older at a Level I trauma center with severe TBI (GCS < 8) from 2011 to 2014. We compared in-hospital mortality, end-of-life (EOL) decision making, discharge functional status, and 12-month survival in responders (GCS > 8 at 72 hours) and nonresponders (GCS ≤ 8 at 72 hours). RESULTS:Of 90 patients, 29 (32%) died within 3 days of injury, 29 (32%) were nonresponders, and 32 (34%) were responders. An additional 19 patients (21%) died before hospital discharge, of whom 17 (89%) were nonresponders. Nonresponders had higher odds of in-hospital death (odds ratio, 31.8; 95% confidence interval [CI], 3.71-272.9; p = 0.002). Family meetings to discuss goals of care were more common in the nonresponder group (p < 0.001) and fewer nonresponders were full code at discharge or death (p < 0.001). There were no significant differences in functional status at discharge. Among patients discharged alive, there were no differences in 12-month survival. CONCLUSION:The responder/nonresponder dichotomy identifies patients with higher in-hospital mortality outcomes and is associated with differences in EOL decision making. However, functional impairment and poor survival were prevalent, irrespective of neurologic status at 72 hours. LEVEL OF EVIDENCE:Prognostic/epidemiologic study, level III; therapeutic study, level IV.

BACKGROUND:Nonoperative management (NOM) is the standard of care in majority of blunt splenic injuries. However, little is known about the postdischarge complications. METHODS:Patients admitted for blunt splenic injury were identified in the California State Inpatient Database (2007 to 2011). We examined patterns and risk factors for postdischarge complications among these patients. RESULTS:In total, 2,704 (61.45%) patients had NOM without splenic artery embolization (SAE) and 257 (5.84%) had NOM with adjunct SAE. Thirty-day readmission rate was higher in those who had adjunct SAE (12.84% vs 7.36%, P = .002). Subsequent operations during readmission were seen in 18.10% of readmitted patients and 38.10% of all patients were readmitted at nonindex hospitals. Major diagnoses on readmission were spleen injury (36.2%) and respiratory complications (9.05%). Adjunct SAE was an independent risk factor for readmission (adjusted odds ratio 1.82, 95% confidence interval 1.19 to 2.78). CONCLUSIONS:Nearly one fifth of readmitted patients initially managed nonoperatively required an operative intervention. Improving predischarge assessments and postdischarge follow-up may reduce readmissions among these patients.
