Application of ventilator care bundle and its impact on ventilator associated pneumonia incidence rate in the adult intensive care unit.

OBJECTIVES: To reduce ventilator associated pneumonia (VAP) incidence rate, lessen the cost of care, and correlate VAP bundles compliance with VAP incidence rate.

METHODS: This study was a prospective longitudinal study conducted on adult intensive care unit (ICU) patients at Hera General Hospital, Makkah, Kingdom of Saudi Arabia from January to December 2010. The following Institute for Healthcare Improvement VAP prevention bundle was applied: head-of-bed elevation; daily sedation-vacation along with a readiness-to-wean assessment; peptic ulcer disease (PUD) prophylaxis; and deep venous thrombosis (DVT) prophylaxis.

RESULTS: Among a total of 2747 patients, the bundle compliance rate in January 2010 was 30%, and reached to 100% in December 2010, while the overall rate was 78.9%. The individual bundle compliance rates were as follows: head-of-bed elevation - 99.9%; daily sedation vacation - 88.9%; PUD prophylaxis - 94.9%; and DVT prophylaxis - 85.7%. At the beginning, VAP rate was 2.5/1000 ventilator days, and reduced to 0.54 in the next month. The overall VAP incidence rate in 2010 was found to be 1.98 with a reduction of 1.41 by comparing with the same data of year 2009 collected retrospectively. The total reduction cost in one year was $154,930. A significant correlation was found between the VAP rate and its bundle compliance (p=0.001). Most frequent pathogens found were Pseudomonas aeruginosa (30.8% of all isolates) followed by Acinetobacter baumannii (27.7%), and methicillin-resistant Staphylococcus aureus (15.4%).

CONCLUSIONS: Application of VAP prevention bundle reduced the VAP incidence rate and lowered the cost of care.
