Epidemiology of acute hypoxaemic respiratory failure in Australian and New Zealand intensive care units during 2005-2022. A binational, registry-based study.

ABSTRACT:

Purpose

Acute hypoxaemic respiratory failure (AHRF) is a common reason for intensive care unit (ICU) admission. However, patient characteristics, outcomes, and trends over time are unclear. We describe the epidemiology and outcomes of patients with AHRF over time.

Methods

In this binational, registry-based study from 2005 to 2022, we included all adults admitted to an Australian or New Zealand ICU with an arterial blood gas within the first 24 h of ICU stay. AHRF was defined as a partial pressure of oxygen/inspired oxygen ratio (PaO₂/FiO₂) ≤ 300. The primary outcome was adjusted in-hospital mortality, categorised based on PaO₂/FiO₂ (mild: 200-300, moderate: 100-200, and severe < 100, and non-linearly). We investigated how adjusted
