Study objectives: To determine whether an educational initiative could decrease rates of ventilator-associated pneumonia in a regional health-care system.Setting: Two teaching hospitals (one adult, one pediatric) and two community hospitals in an integrated health system.Design: Preintervention and postintervention observational study.Patients: Patients admitted to the four participating hospitals between January 1, 1999, and June 30, 2002, who acquired ventilator-associated pneumonia.Intervention: An educational program for respiratory care practitioners and ICU nurses emphasizing correct practices for the prevention of ventilator-associated pneumonia. The program included a self-study module on risk factors for, and strategies to prevent, ventilator-associated pneumonia and education-based in-services. Fact sheets and posters reinforcing the information were posted throughout the ICU and respiratory care departments.Measurements and results: Completion rates for the module were calculated by job title at each hospital. Rates of ventilator-associated pneumonia per 1,000 ventilator days were calculated for all hospitals combined and for each hospital separately. Overall 635 of 792 ICU nurses (80.1%) and 215 of 239 respiratory therapists (89.9%) completed the study module. There were 874 episodes of ventilator-associated pneumonia at the four hospitals during the 3.5-year study period out of 129,527 ventilator days. Ventilator-associated pneumonia rates for all four hospitals combined dropped by 46%, from 8.75/1,000 ventilator days in the year prior to the intervention to 4.74/1,000 ventilator days in the 18 months following the intervention (p < 0.001). Statistically significant decreased rates were observed at the pediatric hospital and at two of the three adult hospitals. No change in rates was seen at the community hospital with the lowest rate of study module completion among respiratory therapists (56%).Conclusions: Educational interventions can be associated with decreased rates of ventilator-associated pneumonia in the ICU setting. The involvement of respiratory therapy staff in addition to ICU nurses is important for the success of educational programs aimed at the prevention of ventilator-associated pneumonia.
Hypothesis: The success of an educational program in July 1999 that lowered the catheter-related bloodstream infection (CRBSI) rate in our intensive care unit (ICU) 3-fold is correlated with compliance with "bestpractice" behaviors.Design: Before-after trial.Setting: Surgical ICU in a referral hospitalPatients: A random sample underwent bedside audits of central venous catheter care (n = 187). All ICU admissions during a 39-month period (N = 4489) were prospectively followed for bacteremia.Interventions: On the basis of audit results in December 2000, a behavioral intervention was designed to improve compliance with evidenced-based guidelines of central venous catheter management.Main Outcome Measures: Compliance with practices known to decrease CRBSI. Secondary outcome was CRBSI rate on all ICU patients.Results: Multiple deficiencies were identified on bed-side audits 18 months after the previous educational program. After the implementation of a separate behavioral intervention in July 2001, a second set of bedside audits in December 2001 demonstrated improvements in documenting the dressing date (11% to 21%; P<.001) and stopcock use (70% to 24%; P<.001), whereas nonsignificant trends were observed in hand hygiene (17% to 30%; P>.99) and maximal sterile barrier precautions (50% to 80%; P =. 29). Appropriate practice was observed before and after the behavioral intervention in catheter site placement, dressing type, absence of antibiotic ointment, and proper securing of central venous catheters. Thirty-two CRBSIs occurred in 9353 catheter-days 24 months before the behavioral intervention compared with 17 CRBSIs in 6152 catheter-days during the 15 months after the intervention (3.4/1000 to 2.8/1000 catheter-days; P=.40).Conclusions: Although a previous educational program decreased the CRBSI rate, this was associated with only modest compliance with best practice principles when bedside audits were performed 18 months later. A behavioral intervention improved all identified deficiencies, leading to a nonsignificant decrease in CRBSIs.
OBJECTIVE:To determine whether there were differences in the microbiologic etiologies of ventilator-associated pneumonia in different clinical settings.DESIGN:Observational retrospective cohort study of microbiologic etiologies of ventilator-associated pneumonia from 1998 to 2001 in a multi-hospital system. Microbiologic results were compared between hospitals and between different intensive care units (ICUs) within hospitals.SETTING:Three hospitals--one pediatric teaching hospital, one adult teaching hospital, and one community hospital--in one healthcare system in the midwestern United States.PATIENTS:Patients at the target hospitals who developed ventilator-associated pneumonia and for whom microbiologic data were available.RESULTS:Seven hundred fifty-three episodes of ventilator-associated pneumonia had culture data available for review. The most common organisms at all hospitals were Staphylococcus aureus (28.4%) and Pseudomonas aeruginosa (25.2%). The pediatric hospital had higher proportions of Escherichia coli (9.5% vs 2.3%; P < .001) and Klebsiella pneumoniae (13% vs 3.1%; P < .001) than did the adult hospitals. In the pediatric hospital, the pediatric ICU had higher P aeruginosa rates than did the neonatal ICU (33.3% vs 17%; P = .01). In the adult hospitals, the surgical ICU had higher Acinetobacter baumannii rates (10.2% vs. 1.7%; P < .001) than did the other ICUs.CONCLUSIONS:Microbiologic etiologies of ventilator-associated pneumonia vary between and within hospitals. Knowledge of these differences can improve selection of initial antimicrobial regimens, which may decrease mortality.
OBJECTIVE:The purpose of the study was to determine whether an education initiative could decrease the hospital rate of ventilator-associated pneumonia.DESIGN:Pre- and postintervention observational study.SETTING:Five intensive care units in Barnes-Jewish Hospital, an urban teaching hospital.PATIENTS:Patients requiring mechanical ventilation who developed ventilator-associated pneumonia between October 1, 1999, and September 30, 2001.INTERVENTIONS:An education program directed toward respiratory care practitioners and intensive care unit nurses was developed by a multidisciplinary task force to highlight correct practices for the prevention of ventilator-associated pneumonia. The program consisted of a ten-page self-study module on risk factors and practice modifications involved in ventilator-associated pneumonia, inservices at staff meetings, and formal didactic lectures. Each participant was required to take a preintervention test before the study module and identical postintervention tests following completion of the study module. Fact sheets and posters reinforcing the information in the study module were also posted throughout the intensive care units and the Department of Respiratory Care Services.MEASUREMENTS AND MAIN RESULTS:One hundred ninety-one episodes of ventilator-associated pneumonia occurred in 15,094 ventilator days (12.6 per 1,000 ventilator days) in the 12 months before the intervention. Following implementation of the education module, the rate of ventilator-associated pneumonia decreased to 81 episodes in 14,171 ventilator days (5.7 per 1,000 ventilator days), a decrease of 57.6% (p <.001). The estimated cost savings secondary to the decreased rate of ventilator-associated pneumonia for the 12 months following the intervention were between $425,606 and $4.05 million.CONCLUSIONS:A focused education intervention can dramatically decrease the incidence of ventilator-associated pneumonia. Education programs should be more widely employed for infection control in the intensive care unit setting and can lead to substantial decreases in cost and patient morbidity attributed to hospital-acquired infections.
