RESUMO
BACKGROUND: Hand hygiene (HH) compliance can be affected by the accessibility of products (alcohol-based products or chlorhexidine) and by the formulations of these products. There are few published studies comparing different alcohol-based hand disinfection formulations. METHODS: This study was conducted in a 41-bed medical-surgical intensive care unit at a private tertiary care hospital. Over a 16-week period, we assessed HH compliance by direct observation of practice using iPods and measurement of the amount of product used [alcohol and chlorhexidine] in two 4-room pods in which an alcohol gel product was used compared with two other 4-room pods in which an alcohol-based foam formulation was used. RESULTS: A total of 3,895 opportunities for HH were observed, and the overall rate of HH compliance was 36.9%. No statistically significant differences were found in overall HH compliance or alcohol-based HH compliance between the alcohol foam unit and the alcohol gel unit. However, there was a statistically significant difference in chlorhexidine HH compliance between the alcohol foam unit and the alcohol gel unit (7.0% [130 of 1,853] vs 3.8% [77 of 2,042]; P < .01). CONCLUSIONS: Alcohol handrub use was greater than chlorhexidine use, but HH compliance was low in both units independent of the alcohol formulation available. The similarity of use of both alcohol formulations suggests that health care workers tend to use whatever product is readily available.

BACKGROUND: Catheter-associated urinary tract infection (CAUTI) is one of the most common health careâassociated infections in the critical care setting. METHODS: A quasi-experimental study involving multiple interventions to reduce the incidence of CAUTI was conducted in a medical-surgical intensive care unit (ICU) and in 2 step-down units (SDUs). Between June 2005 and December 2007 (phase 1), we implemented some Centers for Disease Control and Preventionârecommended evidence-based practices. Between January 2008 and July 2010 (phase 2), we intervened to improve compliance with these practices at the same time that performance monitoring was being done at the bedside, and we implemented the Institute for Healthcare Improvement's bladder bundle for all ICU and SDU patients requiring urinary catheters. RESULTS: There was a statistically significant reduction in the rate of CAUTI in the ICU, from 7.6 per 1,000 catheter-days (95% confidence interval [CI], 6.6-8.6) before the intervention to 5.0 per 1,000 catheter-days (95% CI, 4.2-5.8; P < .001) after the intervention. There also was a statistically significant reduction in the rate of CAUTI in the SDUs, from 15.3 per 1,000 catheter-days (95% CI, 13.9-16.6) before the intervention to 12.9 per 1,000 catheter-days (95% CI, 11.6-14.2) after the intervention (P = .014). CONCLUSION: Our findings suggest that reducing CAUTI rates in the ICU setting is a complex process that involves multiple performance measures and interventions that can be applied to SDU settings as well.

OBJECTIVE: To compare 3 measures of hand hygiene adherence-direct observation, product usage, and electronic counting devices-in an intensive care unit. DESIGN: A 12-week observational study. SETTING: A 40-bed medical-surgical intensive care unit at a private tertiary care hospital. METHODS. Over a 12-week period, we assessed hand hygiene adherence by 3 different methods: direct observation of practice, collection of data from electronic counters for dispensers of alcohol-based hand rub, and measurement of the amount of product used (alcohol-based hand rub and chlorhexidine). RESULTS: There were 2,249 opportunities for hand hygiene observed, and the overall rate of hand hygiene adherence was 62.3% (representing 1,402 cleansing episodes). A total of 76,389 dispensing episodes were recorded by the electronic devices. The mean number of dispensing episodes per patient-day was 53.8. There was 64.1 mL of alcohol-based hand rub used per patient-day (representing 65.5% of total product used) and 33.8 mL of chlorhexidine used per patient-day (representing 34.5%). There was no significant correlation between observed hand hygiene adherence and total product used per patient-day (r=0.18; P=.59). CONCLUSIONS: Direct observation cannot be considered the gold standard for assessing hand hygiene, because there was no relationship between the observed adherence and the number of dispensing episodes or the volume of product used. Other means to monitor hand hygiene adherence, such as electronic devices and measurement of product usage, should be considered.

BACKGROUND: Central line-associated bloodstream infection (CLABSI) is one of the most important health care-associated infections in the critical care setting. METHODS: A quasiexperimental study involving multiple interventions to reduce the incidence of CLABSI was conducted in a medical-surgical intensive care unit (ICU) and in 2 step-down units (SDUs). From March 2005 to March 2007 (phase 1 [P1]), some Centers for Disease Control and Prevention evidence-based practices were implemented. From April 2007 to April 2009 (P2), we intervened in these processes at the same time that performance monitoring was occurring at the bedside, and we implemented the Institute for Healthcare Improvement central line bundle for all ICU and SDU patients requiring central venous lines. RESULTS: The mean incidence density of CLABSI per 1000 catheter-days in the ICU was 6.4 in phase 1 and 3.2 in phase 2, P < .001. The mean incidence density of CLABSI per 1000 catheter-days in the SDUs was 4.1 in phase 1 and 1.6 in phase 2, P = .005. CONCLUSION: These results suggest that reducing CLABSI rates in an ICU setting is a complex process that involves multiple performance measures and interventions that can also be applied to SDU settings.

BACKGROUND: Ventilator-associated pneumonia (VAP) is one of the most common health care-associated infections (HAIs) in critical care settings. OBJECTIVE: Our objective was to examine the effect of a series of interventions, implemented in 3 different periods to reduce the incidence of VAP in an intensive care unit (ICU). METHODS: A quasiexperimental study was conducted in a medical-surgical ICU. Multiple interventions to optimize VAP prevention were performed during different phases. From March 2001 to December 2002 (phase 1: P1), some Centers for Disease Control and Prevention (CDC) evidence-based practices were implemented. From January 2003 to December 2006 (P2), we intervened in these processes at the same time that performance monitoring was occurring at the bedside, and, from January 2007 to September 2008 (P3), we continued P2 interventions and implemented the Institute for Healthcare Improvement's ventilator bundle plus oral decontamination with chlorhexidine and continuous aspiration of subglottic secretions. RESULTS: The incidence density of VAP in the ICU per 1000 patient-days was 16.4 in phase 1, 15.0 in phase 2, and 10.4 in phase 3, P=.05. Getting to zero VAP was possible only in P3 when compliance with all interventions exceeded 95%. CONCLUSION: These results suggest that reducing VAP rates to zero is a complex process that involves multiple performance measures and interventions.
