The VAP Prevention Paradox VAP Rates Vent LOS ICU LOS Hospital LOS Death Regular oral care with chlorhexidine Silver-coated endotracheal tubes Head-of-bed elevation Crit Care 2009;13:315

Silver-Coated Endotracheal Tubes VAP Rates and Outcomes VAP Incidence VAPs per 100 Patients Conventional ETTsSilver coated ETTs Lengths of Stay (days) Vent days ICU days Hospital days JAMA 2008;300:805

Routine Oral Care with Chlorhexidine Meta-analysis suggests CHG lowers VAP rates Risk Ratio 0.72 ( ) Lancet Infectious Dis 2011;11:845

Routine Oral Care with Chlorhexidine Impact on mean duration of mechanical ventilation: NONE! Impact on ICU length-of-stay NONE! Impact on mortality POSSIBLE INCREASE!!! RR 1.13 (0.99 to 1.28) JAMA Internal Med 2014;174:751

Why the Paradox? “VAP” as measured includes a multitude of conditions, ranging from benign to serious  Less serious: bacterial colonization superimposed upon atelectasis / CHF / barotrauma  More Serious: pneumonia, ARDS, pulmonary infarction, others Most prevention measures work by decreasing oral secretions or bacterial colonization  Circularity between mechanism of action and diagnostic criteria  Preferential impact on less serious events leading to lower perceived VAP rates, smaller impact on more serious events For any given intervention, difficult to know if primary impact is on less serious or more serious events since both count as “VAPs” Klompas, Critical Care 2009;13:315

Critical Care Medicine 2013;41:

Ventilator -associated conditions (VAC) Rise in daily minimum PEEP ≥3cm or FiO2 ≥20 sustained ≥2 days after ≥2 days of stable or improving daily minimum PEEP or FiO2

Impact of VAEs on length-of-stay Controlled for time to VAE, age, sex, unit, comorbidities, severity of illness. All comparisons are to patients without VAE (control).

The VAP Prevention Paradox VAP Rates Vent LOS ICU LOS Hospital LOS DeathVAEs Regular oral care with chlorhexidine ? Silver-coated endotracheal tubes ? Head-of-bed elevation ? Crit Care 2009;13:315

The Upshot VAP rates are unreliable outcomes VAE rates likely reliable but still very new. Unclear how best practices will impact them. If we want to know whether a prevention measure really works or not, we have to look at objective outcomes such as: duration of mechanical ventilation ICU length-of-stay hospital length-of-stay mortality

Summary VAP diagnosis is subjective and non-specific Inconsistent association between VAP and patient outcomes Many interventions purportedly lower VAP rates but no impact on patient outcomes: “the VAP Prevention Paradox”. Makes VAP an unreliable outcome VAEs more objective and consistently predict adverse outcomes… but the definitions are still very new, very little data so far on how prevention strategies impact VAE rates Implication: need to look at objective outcomes if we want to be sure that CUSP 4 MVP is helping our patients
