A Prospective Randomized Controlled Trial of Early Non-Invasive Positive Pressure Ventilation in Patients With Hypoxemic Respiratory Failure and Malignancies
Summary
This randomized clinical trial studies how well non-invasive ventilation works in reducing the need for intubation, or placement of a tube in the windpipe, in patients with cancer and respiratory failure. Respiratory failure is a condition in which not enough oxygen passes from the lungs to the blood, and is a common cause of admission to the emergency room in patients with hematological and solid tumor patients. Non-invasive positive pressure ventilation (NIPPV) is a method of delivering oxygen using a mask. It is not yet known whether NIPPV is better at improving the amount of oxygen in the blood, reducing shortness of breath, and the need for intubation than standard high flow oxygen (a tube with 2 prongs placed in the nostrils) in patients with cancer and respiratory failure.
Detailed description
PRIMARY OBJECTIVES: I. To determine the percent of patients who meet criteria for intubation within 28 days of study inclusion. OUTLINE: Patients are randomized to 1 of 2 arms. ARM A (NIPPV THERAPY): Patients undergo intermittent NIPPV, with the recommended schedule comprising 2 hours on NIPPV followed by =\< 2 hours off NIPPV and continuous NIPPV at night or while sleeping for 8 hours per day, for 28 days or until discharged from the hospital. ARM B (HIGH FLOW OXYGEN THERAPY): Patients continue to receive high flow nasal cannula oxygen therapy using current protocol for titration of high flow oxygen therapy for 28 days or until discharged from the hospital. Patients may receive NIPPV if they develop evidence of accessory muscle use with breathing or at the discretion of the treating physician. IDIOPATHIC PULMONARY SYNDROME (IPS) SUBGROUP (INCLUDING DIFFUSE ALVEOLAR HEMORRHAGE): Patients with IPS receive methylprednisolone daily on days 0-48 and every other day (QOD) on days 49-55 in parallel with NIPPV or oxygen therapy, with a taper at the discretion of the treating physician. After completion of study, patients are followed up until day 100.

Outcome measures
Primary
Percent of patients who require intubation or meet criteria for intubation
Fisher's exact test or a chi-squared test will be used to assess the association between two categorical variables. The intubation rate by 28 days and 95% confidence intervals will be estimated for each treatment arm. Logistic regression will be utilized to assess the effect of patient prognostic factors on the intubation rate by 28 days.
Time frame: Up to 28 days from study inclusion
