RESUMEN
IMPORTANCE: Antibiotic-resistant bacteria are associated with increased patient morbidity and mortality. It is unknown whether wearing gloves and gowns for all patient contact in the intensive care unit (ICU) decreases acquisition of antibiotic-resistant bacteria. OBJECTIVE: To assess whether wearing gloves and gowns for all patient contact in the ICU decreases acquisition of methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) compared with usual care. DESIGN, SETTING, AND PARTICIPANTS: Cluster-randomized trial in 20 medical and surgical ICUs in 20 US hospitals from January 4, 2012, to October 4, 2012. INTERVENTIONS: In the intervention ICUs, all health care workers were required to wear gloves and gowns for all patient contact and when entering any patient room. MAIN OUTCOMES AND MEASURES: The primary outcome was acquisition of MRSA or VRE based on surveillance cultures collected on admission and discharge from the ICU. Secondary outcomes included individual VRE acquisition, MRSA acquisition, frequency of health care worker visits, hand hygiene compliance, health careassociated infections, and adverse events. RESULTS: From the 26,180 patients included, 92,241 swabs were collected for the primary outcome. Intervention ICUs had a decrease in the primary outcome of MRSA or VRE from 21.35 acquisitions per 1000 patient-days (95% CI, 17.57 to 25.94) in the baseline period to 16.91 acquisitions per 1000 patient-days (95% CI, 14.09 to 20.28) in the study period, whereas control ICUs had a decrease in MRSA or VRE from 19.02 acquisitions per 1000 patient-days (95% CI, 14.20 to 25.49) in the baseline period to 16.29 acquisitions per 1000 patient-days (95% CI, 13.48 to 19.68) in the study period, a difference in changes that was not statistically significant (difference, −1.71 acquisitions per 1000 person-days, 95% CI, −6.15 to 2.73; P = .57). For key secondary outcomes, there was no difference in VRE acquisition with the intervention (difference, 0.89 acquisitions per 1000 person-days; 95% CI, −4.27 to 6.04, P = .70), whereas for MRSA, there were fewer acquisitions with the intervention (difference, −2.98 acquisitions per 1000 person-days; 95% CI, −5.58 to −0.38; P = .046). Universal glove and gown use also decreased health care worker room entry (4.28 vs 5.24 entries per hour, difference, −0.96; 95% CI, −1.71 to −0.21, P = .02), increased room-exit hand hygiene compliance (78.3% vs 62.9%, difference, 15.4%; 95% CI, 8.99% to 21.8%; P = .02) and had no statistically significant effect on rates of adverse events (58.7 events per 1000 patient days vs 74.4 events per 1000 patient days; difference, −15.7; 95% CI, −40.7 to 9.2, P = .24). CONCLUSIONS AND RELEVANCE: The use of gloves and gowns for all patient contact compared with usual care among patients in medical and surgical ICUs did not result in a difference in the primary outcome of acquisition of MRSA or VRE. Although there was a lower risk of MRSA acquisition alone and no difference in adverse events, these secondary outcomes require replication before reaching definitive conclusions.

BACKGROUND: Central line-associated bloodstream infections (CLABSI) contribute to increased morbidity, mortality, length of stay, and excessive cost of care. METHODS: This study was an observational cohort study using historical controls in the setting of a 9-bed surgical intensive care unit in a Level I trauma center; all patients admitted or transferred into the unit were enrolled in the study. OBJECTIVES: A quality improvement intervention protocol was instituted to reduce CLABSI incidence with a 3-month effectiveness study using 2% chlorhexidine gluconate-impregnated cloths for daily patient bathing; education of surgical intensive care unit staff on changes to CLABSI prevention protocol and all existing CLABSI prevention policies and bundles already in place; and compliance monitoring and documentation. RESULTS: The 3-month effectiveness study showed a decrease in CLABSI rates from 12.07 CLABSIs per 1000 central line-days to 3.17 CLABSIs per 1000 central line-days (73.7% rate reduction; P = .0358). CONCLUSION: CLABSI incidence rates were reduced in a high-risk patient population using evidence-based prevention bundles and implementing daily bathing with 2% chlorhexidine gluconate nonrinse cloths.
