Ventilator-Associated Pneumonia (VAP)

What is ventilator-associated pneumonia?

Ventilator-associated pneumonia (VAP) is a serious hospital-acquired infection of the lungs. VAP occurs when germs enter the lungs through breathing aids, like ventilators or respirators, and cause infection.

Why do we measure?

  • VAP can make a patient sicker, prolong recovery and increase length of hospital stay.

  • Rate of VAP can indicate how safe our environment is for patients.

How do we measure?

The rate of VAP is calculated using the total number of patients infected for every 1,000 ventilator days.

How are we improving?

  • We participated in the Center for Disease Control's National Healthcare Safety Network to monitor and reduce VAP.

  • We take important steps to reduce VAP, including:

    • Limiting ventilator use

    • Enforcing strict guidelines for  hand washing

    • Enforcing proper guidelines for care of vent equipment

    • Providing good mouth hygiene

We report our data using what is known as a control chart. There are four elements on the chart. 1) The blue diamonds: these are the actual data points for each month. They depict the event rate as defined on the vertical axis. 2) and 3): The dotted red lines: these are the upper and lower control limits. They are scientifically calculated to represent the statistical range within which normal random variation occurs in a stable system. 4) The solid red line. This is the average of the blue diamonds for that time frame. As long as the blue diamonds are within the dotted red lines, the system being measured is a stable one. There are certain patterns of blue diamond configuration (e.g. diamonds outside the control limits), that mean something in the system has changed. This is called special cause variation and will usually involve a deeper investigation as to why the new pattern of variation. Each control chart contains an arrow which indicates the desired change direction. For most harm events, the desired direction is down (i.e. less harm is better). For other measures (compliance rates, days between harm events) the desired direction is up.
