There is good evidence that all invasively ventilated patients should undergo lung-protective ventilation (LPV) [1, 2]. As well as LPV, there is a strong evidence base for other routine interventions in the care of ventilated patients. We performed a one day snapshot audit and survey of attitudes towards invasive ventilation practice in intensive care units across the Severn (Bristol,UK) region.
1. To determine compliance with the central components of the Institute for Healthcare Improvement (IHI) Ventilator Bundle
2. To audit use of continual waveform capnography in all ventilated patients
3. To audit the use of LPV
4. To concurrently survey the opinions of senior ICU staff towards the management of ventilated patients
A 24-hour snapshot audit and survey were conducted in regional Intensive Care Units (ICUs). All invasively ventilated patients were included. Data collected included ventilation parameters, use of waveform capnography, Selective oral decontamination and patient position. The on-call consultant(s) and nurse in charge were surveyed to establish individual opinion regarding the use of invasive ventilation.
Ethical approval was obtained from the local R&D departments prior to starting the study.
Considerable variability in ventilation practice exists between the ICU's of this region, particularly in adherence to LPV. There was also a significant disconnect between the care physicians perceived they were delivering and the reality of their practice with low tidal volume ventilation and head-up positioning. The reasons for this are unclear, but have been observed in other similar studies . This questions the validity of surveys alone in assessing clinical practice.
