简要总结
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 (HRF) and ARDS with Protection, Paralysis, and Proning (TheraPPP) Pathway.
The purpose of this pilot study is to test the feasibility and acceptability of the TheraPPP Pathway. To assess feasibility, the investigators will test the ability to measure adherence to the pathway as well as patient and economic outcomes. To assess perceptions about the acceptability of the TheraPPP Pathway, the investigators will conduct a survey to clinicians who used the Pathway.
详细描述
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 objective of this pilot before and after study is to evaluate the feasibility and acceptability of the TheraPPP Pathway.
The pilot study will use a before and after quasi-experimental design to evaluate the feasibility and acceptability of the TheraPPP pathway. The TheraPPP pathway is a comprehensive evidence-based, stakeholder-informed pathway for the diagnosis and management of HRF. The study will be conducted in a single center mixed medical surgical ICU. The study population will include all patients who are admitted to the ICU and are mechanically ventilated.
The pathway will be implemented over a one month period, followed by a one year post implementation assessment period. The comparison (control) therapy will be usual management assessed in the one year pre-implementation period. We estimate approximately 1000 patients will be included in the study.
The primary objectives of the pilot study will be to assess feasibility and acceptability. To assess feasibility, the investigators will test the ability to measure: (1) Fidelity through 5 process of care indicators (2) Patient and economic outcomes. To assess the acceptability of the Pathway, the investigators will conduct a survey to clinicians who used the pathway. The acceptability survey will be sent to approximately 250 ICU clinicians.
For data analysis, no specific comparisons will be made as the investigators are testing the ability to measure the outcomes. However, feasibility and acceptability data will be presented in aggregate as frequency with proportion or median with interquartile range, as appropriate.

结局指标
主要结局
ACCEPTABILITY Pathway Acceptability measured using the Theoretical Framework of Acceptability (TFA)
时间窗: 4 months (after the post-implementation period)
The primary outcome for acceptability is the proportion of seven TFA constructs (7 constructs of acceptability) graded with a median score of 5 or above from a 7-point Likert scale, indicating agreement.
FEASIBILITY (Fidelity) Fidelity of the intervention using a composite fidelity score
时间窗: 4 months (after the post-implementation 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 ≥24 hours, 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 stratified by volume and pressure control (step2/3) 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).
FEASIBILITY (Economic) Cost per safe ventilation day
时间窗: 4 months (after the post-implementation period)
Cost per safe ventilation day from the perspective of the health care system
