Patient-Ventilator Asynchrony: Occurence and Clinical Impact in Usual Care (PVA-detection)
Unraveling the Clinical Impact of Patient-Ventilator Asynchrony in Usual Care
The goal of this observational study is to unravel the occurence, impact and relations of Patient-Ventilator Aynchrony (PVA) in mechanically ventilated patients. The main questions it aims to answer are:
- How often does PVA occur?
- What are relations between clinical characteristics and PVA occurence?
- What are relations between PVA occurence and patient outcomes?
All questions will be assessed using data collected during the whole course of mechanical ventilation. Mechanically ventilated patients' medical data will be re-used. PVAs will be automatically classified on ventilator waveform data, using validated Deep Breath software.

Description détaillée
Many ventilated patients show excessive breathing efforts and abnormal, irregular breathing. This patient-ventilator asynchrony (PVA) is associated with serious discomfort, lung injury, sleep disruption and higher mortality. PVA exists in many forms and is reported in 10-90% of patients, but identifying and resolving it is challenging, even for expert clinicians. Hence, PVA prevalence and impact is likely highly underestimated, and the direct causal link with worse outcomes is inconclusive. PVAs should be better dettected, understood and resovled to optimize the individual patient's treatment.
In a previous study, the investigators validated an AI-based algorithm capable of reliable PVA detection (Deep Breath software). In this study, the investigators will apply this algorithm to the collected ventilator waveform data (offline processing), in order to reliably assess PVA occurrence, and its relation with clinical outcomes and patient characteristics in current clinical care. Data of minimally 110 patients collected over the whole course of mechanical ventilation will be assessed. Patients will be included in three ICUs to promote generalizability.
The primary outcome will be the asynchrony index (in total and per PVA type) over time. Secondary outcomes will include, but are not limited to: clinical characteristics (e.g. respiratory and hemodynamic parameters, sedation), (ICU) mortality, ventilator free days at day 28 and 90, duration of ventilation, weaning success and reintubation rate.

Cohortes et interventions
Groupe / Cohorte |
Intervention / Traitement |
|---|---|
|
Adult patients admitted to the ICU that receive invasive mechanical ventilation
Patients need to be >18 years old, receive mechanical ventilation for at least 24 hours and have recordings available of ventilator waveforms, synchronized with the patient's electronic health record, during invasive mechanical ventilation.
|
Patients will receive standard care, without an intervention.
Data will be captured as part of standard care and analyzed for PVAs retrospectively, using dedicated offline software.

Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Asynchrony index over time (aggregated and per PVA type)
Délai: 28 days
|
Measure of how much asynchrony occurs and at what time.
This measure will be calculated for all PVA types together, as well as per PVA type.
The investigators calculate this over time, to see when asynchrony occurs, as well as in total, to get a global PVA prevalence measure (over the whole duration of ventilation).
