Noninvasive ventilation (NIV) is commonly used to treat acute respiratory failure (ARF) with the goal of preventing endotracheal intubation (ETI). Duan et al. recently developed and validated the HACOR scale, which utilizes multiple objective variables, to help predict patients likely to fail NIV for hypoxemic respiratory failure. We prospectively applied this scale in an international, multicenter, observational study to explore its utility predicting NIV failure for all types of ARF, and associated outcomes. Across 5 countries, we recruited patients aged >18 placed on NIV during hospitalization, totaling 77. We adopted the same HACOR scale and score cutoff from the original study, and examined if outcomes differed for those who scored >5, or A total of 45 patients had an initial score 5, 50% were later intubated. In this group, 62% with improved scores and 67% with unchanged or worsened scores were intubated. Average time to ETI for scores >5 was 40 hours. In-hospital mortality between initial score 5 were 22% and 28%, respectively. We validated the HACOR scale for all types of ARF. Scores >5 had higher rates of ETI. Rates were lowest for those with initial score |
