To evaluate the performance of the Prognosis for Prolonged Ventilation (ProVent) 14 score in patients requiring prolonged mechanical ventilation (PMV).Data were obtained from 366 patients receiving at least 14 days of MV between January 2011 and December 2015 at a university-affiliated tertiary care hospital in Korea. ProVent 14 scores were assessed using the six standard variables. Model discrimination was assessed with the area under the receiver operating characteristic curve. Kaplan-Meier estimates were stratified according to the ProVent 14 score to predict 1-year survival.The median age of the study group was 62 years (range, 50–72 years); 65% were male, and medical patients comprised 66% of the group. Overall mortality at 1 year was 43%. For ProVent 14 scores ranging from 0 to ≥4, 1-year mortality rates were 7%, 22%, 41%, 52%, and 75%, respectively (log-rank test, P < 0.001). The area under the receiver operating characteristic curve of the ProVent 14 score predicting 1-year mortality was 0.74 (95% confidence interval, 0.69–0.78).The ProVent 14 score accurately identified patients receiving PMV with a high 1-year mortality risk. Further validation in a larger sample is required.The performance of the ProVent 14 score was validated in patients requiring PMV.ProVent 14 score accurately predicts the 1-year mortality risk in Korean patients.A simplified ProVent 14 model did not improve the score's performance.Inclusion of additional variables did not improve the score's performance.
