Root cause analysis of ventilator-associated pneumonia and the effect of analysis of expanded ventilator bundle of care

Abstract EN

Objectives The study had the following aims: (i) assess the risk factors and causes of ventilator-associated pneumonia (VAP) by means of the root cause analysis (RCA) module; (ii) compare the compliance with expanded ventilator bundle ( EVB) and the effect of EVB on VAP rate, length of ICU stay ( LOS), and mortality rate before and after bundle implementation; and (iii) suggest an action plan to reduce VAP.

Patients and methods An 18-month study was conducted on all ventilated patients in our ICU.

The preinterventional period was 9 months before implementing the bundle.

We analyzed the causes and risk factors of VAP by using the RCA module.

The postinterventional period was 9 months after implementing the bundle.

Compliance with EVB was compared before and after implementing the bundle on a quarterly basis.

We analyzed the effect of the bundle on VAP rate, LOS, and mortality rate.

We suggested an action plan to reduce the VAP rate.

Results There was lower compliance with the bundle in the preinterventional period than in the postinterventional period (P < 0.001).

There were highly statistically signifi cant reductions in VAP rate, LOS, and mortality rate after implementation of EVB (P < 0.001).

Conclusion EVB was associated with effective and signifi cant reductions in VAP rate, LOS, and mortality rate.

Implementation of the RCA module was helpful in suggesting a new action plan that would improve bundle of care and its compliance.
