Overview
Brief Summary
Treatment of patients with Hypoxemic respiratory failure (HRF) and Acute Respiratory Distress Syndrome (ARDS) is complex. Therapies that have been shown to save the lives of patients with HRF and ARDS are available but they are not always provided. To reduce practice variation and improve adherence to evidence-informed therapies, the investigators developed the Treatment of Hypoxemic Respiratory Failure and ARDS with Protection, Paralysis, and Proning (TheraPPP) Pathway.
The overall objective of TheraPPP Pathway is to improve the quality of care for patients with HRF. Implementation of the pathway across Alberta will test the effectiveness and implementation of the TheraPPP Pathway.
Detailed Description
Hypoxemic respiratory failure (HRF) and ARDS are common conditions among patients admitted to the Intensive care unit (ICU). Treatment of these patients is complex. Evidence based therapies that can improve survival exist; however, implementation is extremely inconsistent. As a potential solution to this problem, the investigators developed the Treatment of Hypoxemic Respiratory Failure (HRF) and ARDS with Protection, Paralysis, and Proning (TheraPPP) Pathway to reduce practice variation and improve adherence to evidence-informed therapy. The TheraPPP pathway is a comprehensive evidence-based, stakeholder-informed pathway for the diagnosis and management of HRF. The overall objective of the pathway is to improve the quality of care for patients with HRF. The specific objectives are to evaluate: 1. Effectiveness of the pathway. A cost-effectiveness analysis is a secondary objective. 2. Implementation of the pathway by conducting a process evaluation which will assess fidelity of the delivered interventions and clinician perceptions about the acceptability of the pathway. Mechanically ventilated patients admitted to any one of 17 adult ICUs in Alberta will receive the intervention. One ICU (Calgary) is the setting for a pilot study (NCT04070053). For data analysis, the investigators will use chart abstraction to quantitatively assess the fidelity of the delivered intervention, and surveys and focus groups to qualitatively assess clinician perceptions about the acceptability of the pathway. Fidelity of the intervention will be tracked using process of care indicators that reflect the five key steps of the pathway.

Outcomes
Primary Outcomes
IMPLEMENTATION (primary fidelity outcome) Composite Fidelity Score
Time Frame: 4 months (after the study post-intervention period)
The composite fidelity score is measured daily for each patient. It is scored out of 5 and awards 1 point for each fidelity indicator (listed below) that investigators are able to measure: 1. If ventilated, is a height measured (step 1) 2. If arterial to inspired oxygen ratio (PaO2:FiO2 ratio or PF ratio) ≤300, is the medial tidal volume ≤8mL/kg (step 2) 3. If PF ratio ≤300, is a plateau pressure measured (step 3) 4. IF patient has HRF and PF ratio ≤150, was neuromuscular blockade used in that 24 hour period (step 4) 5. If the patient has HRF and PF ratio ≤150 and FiO2 ≥0.6, did the patient receive prone ventilation (step 5)
ECONOMIC (primary economic outcome) Cost per ventilator free day saved
Time Frame: 4 months (after the study post-intervention period)
Cost per ventilator free day saved from the perspective of the health care system over the index hospitalization period
EFFECTIVENESS (primary clinical outcome) 28-day ventilator free days
Time Frame: 4 months (after the study post-intervention period)
A composite outcome of survival and days spent not ventilated over the first 28 days
