Collecting Connect VAE data can be used to— the dots to harm Avoid failure of infection prevention efforts due to “silo mentality” View interventions under the larger context of patient safety WHY COLLECT VAE DATA? AHRQ Safety Program for Mechanically Ventilated Patients VAE Surveillance 7
A retrospective cohort study examining 20, 356 episodes of mechanical ventilation (MV)1 VAEs 1, 141 ventilator-associated conditions (VACs) 431 infection-related VACs (IVACs) 266 possible cases of ventilator-associated pneumonia (PVAP) Patients with a VAE have— More days to extubation More days to discharge Higher mortality rate WHY DO I WANT TO KNOW ABOUT VACS AND IVACS?

Screening ventilator settings for VAC captures a similar set of complications to traditional VAP surveillance but is faster, more objective, and a superior predictor of outcomes. 2 Objective surveillance definitions that include quantitative evidence of respiratory deterioration after a period of stability strongly predict increased LOS and hospital mortality. 3 WHY USE THE NEW VAE SURVEILLANCE DEFINITIONS? AHRQ Safety Program for Mechanically Ventilated Patients VAE Surveillance 10
• One of the main reasons is interrater reliability. This occurs when two people separately look at the same set of criteria and do, or don’t, come up with the same conclusion • Criteria are subjective, leading to disagreement between reviewers ) WHY THE CHANGE? AHRQ Safety Program for Mechanically Ventilated Patients VAE Surveillance 11
Broaden the focus Shifting focus of surveillance from pneumonia alone to complications in general emphasizes the importance of preventing all complications of MV, not just pneumonia When definitions are objective, caregivers can focus on what went wrong rather than debate the definition WHY THE SHIFT? AHRQ Safety Program for Mechanically Ventilated Patients VAE Surveillance 12
The definition of VAE is intentionally broader than traditional VAP surveillance Common VACs: ARDS PE Thromboembolic disease Sepsis Clinical ramifications? Respiratory deterioration in previously stable patients is a risk factor for increased morbidity and mortality BROADENING THE SURVEILLANCE AHRQ Safety Program for Mechanically Ventilated Patients VAE Surveillance 13
Multicenter, retrospective study Evaluated a novel surveillance paradigm for VACs: screening ventilator settings Blinded critical care physician reviewed 52 randomly selected patients with VAC (defined by protocol) or VAP (determined by IPs based on VAP definition) Screening ventilator settings for VAC captures a similar set of complications to traditional VAP surveillance ANALYSIS OF VAC VS.

Many providers feel some of the conditions associated with VAEs are pre-existing Preliminary data from the first year of VAE data collection showed approximately 79 percent of VAEs were in patients who were either on MV for ≥ 5 days or in the hospital for ≥ 5 days at the time of VAE onset 6 Time to onset data suggest that the majority of VAEs are likely hospital-associated based on previous criteria 7, 8 ARE VAES PREVENTABLE?

INTERVENTION BUNDLE CHECKLIST PROCESS MEASURE DATE Y/N COMMENTS Continuous subglottic suctioning Assess readiness to extubate with spontaneous breathing trials (SBTs) Paired SBTs and SATs Interrupt sedation daily with spontaneous awakening trials (SATs) Note contradictions here Ambulate according to protocol Note level here Regular mouth care (without chlorhexidine) Elevate head of bed (HOB) 30– 450 Conservative fluid management Blood transfusions given Rationale: Low tidal volume Identify: AHRQ Safety Program for Mechanically Ventilated Patients VAE Surveillance 18
RECOMMENDATION INTERVENTION Basic practice • • Use noninvasive positive pressure ventilation in selected populations Manage patients without sedation whenever possible Interrupt sedation daily Assess readiness to extubate daily Perform SATs with sedatives turned off Facilitate early mobility Use endotracheal tubes with subglottic secretion drainage ports for patients expected to require greater than 48 or 72 hours of MV Change the ventilator circuit only if visibly soiled or malfunctioning Elevate HOB to 30– 45° • • Select oral or digestive decontamination Regular oral care with chlorhexidine Prophylactic probiotics Ultrathin polyurethane endotracheal tube cuffs Automated control of endotracheal tube cuff pressure Saline instillation before tracheal suctioning Mechanical tooth brushing • • • Silver-coated endotracheal tubes Kinetic beds Prone positioning • • Special approaches BEST PRACTICES FOR VAE REDUCTION Generally not recommended AHRQ Safety Program for Mechanically Ventilated Patients VAE Surveillance 19
