%X BACKGROUND: Severe respiratory failure requires numerous interventions and its clinical implementation changes over time. We aimed to clarify the clinical practice and prognosis of severe respiratory failure and its changes over time.
METHODS: In a nationwide Japanese administrative database from 2016 to 2019, we identified nonoperative patients with severe respiratory failure without congestive heart failure as the main diagnosis who received mechanical ventilation (MV) for more than four days. We examined trends in patient characteristics, adjunctive interventions, and prognosis.
RESULTS: Among 66,905 patients included in this study, patients received antibiotics (90%), high-dose corticosteroids (14%), low-dose corticosteroids (18%), and 51% were admitted to the critical care unit. Hospital mortality was 35%. Median mechanical ventilation lasted 10 days. Tracheostomy occurred in 23% of cases. Median critical care and hospital stays were 10 and 25 days, respectively. Among survivors, 23% had mechanical ventilation dependency at hospital discharge. Large relative changes in adjunctive therapies included fentanyl (30%-38%), rocuronium (4.4%-6.7%), vasopressin (3.8%-6.0%), early rehabilitation (27%-38%), extracorporeal membrane oxygenation (0.7%-1.2%), dopamine (15%-10%), and sivelestat (8.6%-3.5%). No notable changes were seen in mechanical ventilation duration, tracheostomy, critical care unit stay, hospital stay, or ventilator dependency at discharge, except for a slight reduction in hospital mortality (36%-34%).
CONCLUSIONS: Several adjunctive therapies for severe respiratory failure changed from 2016 to 2019, with an increase in evidence-based practices and a slight decrease in hospital mortality.
