Abstract

Objective: There have been a large number of studies that have investigated the relationship between outcomes and provider volume for a wide variety of medical conditions and surgical conditions. The objective of this study was to explore the relation between hospital volume and risk- adjusted mortality following percutaneous coronary intervention between 2003 and 2004 in Korea. Methods: This is a retrospective analysis of database in National Health Insurance Review & Assessment Service and Korean National Statistical Office. The study data set confined to the ICD-10 diagnosis and procedure codes that were recorded in the National Health Insurance Review Agency. Risk modeling was performed through logistic regression and validated with cross-validation. The statistical performance of the developed model was evaluated using c-statistics, R2, and Hosmer-Lemeshow statistic. Crude and risk-adjusted 30-day mortality was evaluated among patients who underwent Percutaneous Coronary Intervention (PCI) between 2003 and 2004 at low (less 200 cases/year), medium (200~399 cases/year), and high (400 cases or more/year) PCI volume hospitals. Results: The final risk-adjustment model consisted of ten risk factors for 30-day mortality. These factors were found to have statistically sig- nificant effects on patient mortality. The c-statistic and Hosmer-Lemeshow χ2 goodness-of-fit test and the model’s performance were good [R2=0.147, c-statistic 0.823, 4.1037 (p=0.8476)]. A total number of 60 low-volume hospitals (9.071 patients) and 27 medium-volume hospitals (15.623 patients) and 15 high-volume hospitals (19.669 patients) were included. Crude 30-day mortality rate was 1.4%, 1.1%, and 1.0% (p=0.0106) in each volume hospitals. But risk-adjusted mortality rate was not significantly different among three groups (1.3%, 1.0%, and 1.1% in each volume hospitals). Conclusion: Although we found a significant different crude 30-day mortality rates according to hospital PCI volume, but did not find a relation- ship between hospital volume and 30-day risk-adjusted mortality rates following PCI in Korea.

Özet

Amaç: Çok değişik tıbbi ve cerrahi durumlar için, hizmet sağlayanın volümü ile sonuçlar arasındaki ilişkiyi araştıran pek çok çalışma vardır. Bu çalışmanın amacı, 2003 ve 2004 yılları arasında Kore'de perkütan koroner girişim sonrası hastane hacmi ve risk-ayarlı mortalite arasındaki iliş- kiyi ortaya çıkarmaktı. Yöntemler: Bu çalışma Ulusal Sağlık Sigorta İnceleme ve Değerlendirme Servisi ve Kore Ulusal İstatistik Ofisi veritabanının retrospektif bir analizidir. Çalışmanın verileri Ulusal Sağlık Sigorta İnceleme Ajansı’nda kaydedilmiş ICD-10 tanı ve işlem kodlarını kapsar. Risk modelleme lojis- tik regresyon yoluyla yapıldı ve çapraz-doğrulama ile doğrulandı. Geliştirilen modelin istatistiksel performansı c-istatistikleri, R2, ve Hosmer- Lemeshow istatistiği kullanılarak değerlendirildi. Basit ve riske ayarlı 30 günlük mortalite, Perkütan Koroner Müdahale (PKM) yapılan hastalar 2003 ve 2004 yılları arasında, düşük (200’den az olgu/yıl), orta (200~399 olgu / yıl) ve yüksek (400 olgularda veya fazla/yıl) PKM hacimli hastane- lerde değerlendirildi. Bulgular: Son risk düzeltme modeli 30-günlük mortalite için on risk faktörinden oluşuyordu. Bu faktörlerin, hasta mortalitesi üzerine anlamlı etkilerinin olduğu saptandı. C-istatistik ve Hosmer-Lemeshow χ2 ``goodness-of-fit`` testi ve modelin performansı iyiydi [R2=0.147, c-statistic 0.823, 4.1037 (p=0.8476)]. Altmış düşük-hacimli hastanenin (9.071 hasta) ve 27 orta-hacimli hastanenin (15.623 hasta) ve 15 yüksek-hacimli has- tanenin (19.669 hasta) toplam sayısı dahil edildi. Basit 30-günlük mortalite oranı her bir hastane volüme için sıra ile %1.4, %1.1 ve her birimin hastanelerde oranı %1.0 (p=0.0106) idi. Buna karşılık, risk ayarlı ölüm oranı üç grup arasında anlamlı değildi (%1.3, %1.0, ve %1.1; her bir hasta- ne volümü için). Sonuç: Kore’de hastane PCI hacmine göre, basit 30-günlük mortalite oranlarında önemli farklılık bulmamıza rağmen PKG sonrası 30 günlük risk- ayarlı ölüm oranları ile hastane hacmi arasında bir ilişki bulamadık.
