dc.description.abstractAmaç: Kliniğimizde açık kalp cerrahisi uygulanacak hastaların Parsonnet risk skorlama sistemiyle hastane performanslarının değerlendirilmesi konusunda örnek olması, ameliyat olacak hastaların risk ağırlıkların ortaya konmasıdır.Materyal ve Metod: Eylül 2002 ? Aralık 2008 tarihleri arasında Kalp Damar Cerrahisi Anabilim Dalında ardışık olarak açık kalp cerrahisi uygulanan 1000 hasta retrospektif incelemeye alındı.Bulgular: Çalışmaya alınan hastaların 310 (%31) kadın, 690 (%69) erkek idi. Yaş dağılımları 3-86 arasında olup, ortalaması 57,66 12,02 olarak hesaplandı. Bu hastaların 42 (%4,2) off-pump tekniği ile, 958 (%95,8) on-pump tekniği ile opere edildi. 128 (%12,8) hasta DM, 281 (%28,1) hasta HT, 101 (%10,1) hasta KOAH, 456 (%45,6) hastada sigara kullanımı, 79 (%7,9) hastanın EF %30, 9 (%0,9) hastaya preoperatif İABP, 9 (%0,9) hastaya preoperatif diyaliz uygulandı. Postoperatif yatış süresi 7,4 4,4 gün idi. Beklenen mortalite %5,71 5,65, additive modele göre gözlenen mortalite %9,4 7,17, multivariate lojistik regresyon modele göre gözlenen mortalite %7,25 10,86 idi. (p<0,001) Düşük risk (0 ? 4 puan) grubunda gözlenen mortalite %4,8, orta risk (5 ? 9 puan) grubunda %12,0 ve yüksek risk (10 ) grubunda %18,2 idi. (p<0,001) Tüm hastalarımızın Parsonnet risk ROC eğrisi altında kalan alan AUC = 0,702 olarak hesaplandı (p<0,001).Sonuç: Hesaplanan ROC değeri ile Parsonnet risk skorlama modelinin, risk belirlemede yeterince güçlü olmadığı sonucuna ulaştık. Türkiye'ye özgü bir risk skorlama sistemini geliştirebilmek için bu konu üzerinde yapılacak daha çok çalışmaya ve güvenilir bir ulusal veritabanına gereksinim olduğunu düşünmekteyiz.Anahtar kelimeler: Parsonnet, mortalite, risk grubu, ROC eğrisi
dc.description.abstractPurpose: To set example about hospital performances using Parsonnet Risc Scoring system on patients those will have open heart surgery in our clinic and to present risc load.Material and Method: 1000 patients who consequently had open heart surgery between September 2002 - December 2008 in our Cardiovascular Surgery Department have been reviewed retrospectifly.Results: 310 (31%) percent of the patients who were included to our study were women and 690 (69%) of the patients were men. Age range was between 3-86 and the mean value was calculated as 57,66 12,02. 42(4,2%) of these patients were operated with off-pump technique, 958 (95,8%) were operated with on-pump techinique. 128 (12,8%) patients were DM, 281 (28,1%) patients were hypertension, 101 (10,1%) patients were COLD (chronic obstructive lung disease), 456 (45,6%) patients were smokers , 79 (7,9%) patients had EF %30, 9 (0,9%) patients had preoperative IABP and 9 (0,9%) patients had preoperative dialysis. Post operative bed time was 7,4 4,4. Expected mortality was %5,71 5,65, mortality with additive model was %9,4 7,17, mortality observed with multivariety logistic regration model was %7,25 10,86 (p<0,001). Low risk (0-4 points) group had a mortality percentage of 4,8, medium risk (5-9 points) group had 12,0%, high risk (10 ) group had 18,2% mortality risc. Patients those were under the Parsonnet Risc Scoring ROC curve were AUC = 0,702 observed.Conclusion: We have concluded that calculated ROC value and Parsonnet Risc scoring model are not very effective in determining riscs. Our opinion is that in order to develop a risc scoring system unique to Turkey we need to have more reliable national database and more studies.Key words: Parsonnet, mortality, risc group, ROC curveen_US
