HACOR score to predict failure of non-invasive ventilation in patients with acute hypoxemic respiratory failure: When simplicity is best

P/F Ratio is a Better Predictor for Non-Invasive Ventilation Failure and Length of Stay in Patients with Community-Acquired Pneumonia

“…However, this does not necessarily mean that the HACOR score is more useful than the P/F ratio, as the difference in accuracy was minimal, and the P/F ratio is more straightforward to apply than the HACOR score. 10,11 Upon reviewing the patients' characteristics, this study found that a higher body temperature during the first 24 hours of admission was significantly correlated with intubation following NIV. Temperature has been included in scoring systems that determine the degree of illness and risk of critical conditions, such as the National Early Warning Score (NEWS) and the Modified Early Warning Score (MEWS).…”

“…The P/F ratio showed a negative correlation coefficient (r = −0.049), which implies that a better P/F ratio might contribute to survival or improvement in clinical conditions during hospitalization. A study performed by the French Intensive Care Society (Société de Réanimation de Langue Française/SRLF) Trial Group (2018) compared the length of ICU stay of hypoxemic patients (P/F ratio less than or equal to 300 mmHg) with non-hypoxemic patients and found that the median length of ICU stays in the hypoxemic group was approximately twice as long (16 [7-32] vs. 8 [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] days, p < 0.001). 24 According to Mammadova, et al (2022), measuring the initial ROX index in patients admitted to the ICU was also helpful in predicting the length of ICU treatment, and the presence of respiratory failure and hypercapnia influenced its cut-off value.…”
