Risk of mortality assessment in pediatric heart surgery

Amaç: Bu çalışmada Pediatrik Mortalite İndeksi (PIM) 1, PIM 2 ve modifiye Ardışık Organ Yetersizlik Değerlendirme (m-SOFA) skorlarının pediatrik kalp cerrahisinde mortalite tahminindeki geçerliliği değerlendirildi. Çalışma plan ı: 2003 Haziran - 2009 Ocak yılları arasında, 12 yataklı ameliyat sonrası kalp cerrahisi yoğun bakım ünitesinde kalp cerrahisi sonrasında izlenen 456 pediatrik hastanın tıbbi dosyası retrospektif olarak incelendi. Bu dosyalardan 373ü çalışmaya dahil edildi. Hastaların yaş, cinsiyet, tanı, yoğun bakımda ve hastanede kalış süreleri, sağkalım oranları, PIM 1, PIM 2 skorları ve başlangıçtaki, 24. ve 48. saatlerdekim-SOFA skorları ile zirve m-SOFA skorları kaydedildi. Normal dağılım gösteren veriler Student t testi, nonparametrik veriler Mann-Whitney-U testi ile karşılaştırıldı. Skorların kalibrasyonu Hosmer ve Lemeshow Uyum İyiliği testi ile yapıldı. Skorların ayırım gücü, Alıcı işletim karakteristikleri (ROC) eğrisi kullanılarak analiz edildi. Bulgular: Ameliyat sırası dönemde 50 hasta (13.4%) kaybedildi. Zirve ve başlangıç m-SOFA skorları, ölen hastalarda (sırasıyla 9.8±2 ve 9.2±2), sağ kalanlara (sırasıyla 5±2.5 ve 4.6±2.5; p

Pediatrik kalp cerrahisinde mortalite riskinin değerlendirilmesi

Background: This study aims to evaluate the validity of Pediatric Index of Mortality (PIM) 1, PIM 2, and modified Sequential Organ Failure Assessment (m-SOFA) scores for predicting mortality in pediatric heart surgery. Methods: Between June 2003 and January 2009, medical files of 456 pediatric patients who were monitored in a 12-bed postoperative cardiac surgery care unit following heart surgery were retrospectively analyzed. A total of 373 files were included in the study. Age, gender, diagnosis, the length of stay in the intensive care unit and hospital, survival rates, PIM 1, PIM 2 scores and m-SOFA scores on admission, at 24 and 48 hours and peak m-SOFA scores were recorded. Student s t test was used to compare the normally distributed data, whereas Mann-Whitney-U test was used to compare non-parametric data. Calibration of the scores was performed using the Hosmer and Lemeshow Goodness of Fit test. Discrimination power of the scores was analyzed using the receiver operating characteristic (ROC) curves. Results: Fifty patients (13.4%) died perioperatively. Peak and m-SOFA scores on admission were significantly higher in non- survivors (9.8±2 and 9.2±2, respectively) than survivors (5±2.5 and 4.6±2.5, respectively; p
