Surveillance for Ventilator-Associated Events in Adults: A New Approach for the National Healthcare Safety

Network (NHSN)

National Center for Emerging and Zoonotic Infectious Diseases

Division of Healthcare Quality Promotion

The Problem

Ventilator-associated pneumonia (VAP) is an important complication of mechanical ventilation But other bad things also happen to patients on ventilators

No valid, reliable definition for VAP Need more accurate diagnostics … Until those are available, how do we conduct surveillance and track

prevention progress? Commonly used definitions include subjective elements and

are neither sensitive nor specific for VAP Not ideal in an era of public reporting of healthcare-associated

infection (HAI) rates, comparisons among facilities, pay-for-performance programs

Need a new approach

At least one of the following:

Fever (> 38 C/100.4 F) with no other cause

Leukopenia (< 4,000 WBC/mm³) or leukocytosis (> 12,000 WBC/mm³)

Altered mental status with no other cause, in > 70 y.o.

PNU2: Pneumonia with common bacterial or

filamentous fungal pathogens and specific lab findings

PNU2: Pneumonia with viral, Legionella, Chlamydia,

Mycoplasma, and other uncommon pathogens and

specific lab findings PNU1: Clinically

defined pneumonia

PNU3: Pneumonia in immunocompromised

Current PNEU Definitions• Three sets of criteria• Chest x-ray evidence required• Signs/symptoms required• Lab evidence used if available

from acceptable specimen type

• VAP is a PNEU event that meets the “ventilator-associated” criterion—

Endotracheal tube (ETT)/ventilator must have been in place at some time during the 48 hours preceding the onset of PNEUNo required amount of time that the ETT/ventilator must have been in place for a PNEU to count as a VAP

Limitations of Current VAP Definitions

References include but are not limited to the following:1Wunderink R, et al., Chest 1992;101;458-63; 2Young M, et al., Arch Intern Med 1994;154:2729-32; 3Fabregas N, et al., Thorax 1999;54:867-73; 4Kirtland SH, et al., Chest 1997;112:445-57; 5Berton DC, et al., Cochrane Database Syst Rev 2008; 6Ruiz M, et al., Am J Respir Crit Care Med 2000;162:119-25.

Working Group Objectives

Critically review CDC’s draft, streamlined VAP surveillance definition for use in adult patients;

Suggest modifications to enhance reliability and credibility within the critical care community;

Propose final adult definition algorithm that will be implemented for use in NHSN for the potential purposes of public reporting, inter-facility comparisons, and federal pay-for-reporting and -performance programs.

Working Group Progress

Kick-off meeting 9/2011, multiple follow up calls Revised definition algorithm—tiered approach

Definitions suitable for potential use in public reporting: objective, general measures of ventilator-associated conditions and complications

• Similar definitions evaluated by Klompas et al. identified events associated with longer duration of mechanical ventilation, longer ICU stay, and increased mortality—and were more efficient to apply than current VAP definitions (PLoS One 2011;6:e18062, Crit Care Med 2012; in press)

Internal use definitions: possible and probable VAP, incorporating laboratory evidence

Research agenda items Mechanism for intensive care unit-level risk adjustment or

stratification (to account for differences in severity of illness) Denominator data collection

VENTILATOR-ASSOCIATED EVENTS (VAE) SURVEILLANCE DEFINITION ALGORITHM

***Note that this is NOT a clinical definition algorithm and is not intended for use in the management of patients.***

Patients Eligible for VAE Surveillance

≥18 years of age Inpatients of acute care hospitals, long term acute care

hospitals, inpatient rehabilitation facilities

NOTE: Patients receiving high frequency ventilation or extracorporeal life support are excluded from surveillance.

Key Operational Details*

In 2013, in-plan surveillance for ventilator-associated PNEU may still be conducted for neonatal and pediatric patients ONLY.

In 2012 and 2013, the PNEU definitions are still available for those units seeking to conduct off-plan PNEU surveillance for mechanically-ventilated adults or non-ventilated adults or children.

Conducting in-plan VAE surveillance means assessing patients for the presence of ALL events included in the algorithm—from VAC to IVAC to Possible and Probable VAP. A unit participating in in-plan VAE surveillance cannot decide, for example, that only surveillance for VAC (and not for IVAC or Possible or Probable VAP) will be performed.

*Preliminary and subject to change.

More Key Operational Details*

“New” antimicrobial agent How to determine whether a new antimicrobial agent has

been given for at least 4 days (including in patients with renal insufficiency)

Single doses of vancomycin Multiple VAEs during a single hospitalization VAEs in patients who’ve been recently extubated Pathogens and secondary BSIs Lung histopathology Diagnostic tests for viruses and Legionella spp. Time frame within which VAE criteria must be fulfilled

*Preliminary and subject to change.

Next Steps

Options for Tracking VAP/VAE Rates, 2012-2013

Implement VAE early Forms and protocol Training Data management

Continue VAP surveillance into 2013 Will remain available off-plan in NHSN application—but probably only

until end of CY 2013 Do both

TIPS FOR SUCCESS

Use the linelist approach

Explore your hospital’s IT environment

• Definitions are amenable to complete automation• …but if IT can only offer semi-automation, still a substantial help

• e.g. automatic linelists with daily vent settings for manual review• Linelists of vent settings PLUS temp / wbc / abx / micro • Linelists + automatically flag VAE

Does respiratory therapy already have an electronic tracking system for vented patients?

• Vent settings sometimes stored electronically but outside the EMR• If not currently tracking vented pts electronically, do they want to start?

If automation not possible, ask respiratory therapy and / or nursing for help collecting daily vent settings
