Abstract

Background: Coronary artery bypass grafting(CABG) imposes large amount of medical costs, which are greatly affected by the surgical approach, quality of perioperative care and associated co-morbidities. Recently, off-pump CABG(OPCAB) has been introduced and performed with increasing frequency. To evaluate the efficacy of OPCAB in view of financial impact, we analyzed the costs and medical resources of OPCAB and compared with conventional CABG. Material and Method: From January 1998 to July 1999, 184 patients underwent CABG operation; 111 patients with OPCAB(group I) and 73 patients with conventional CABG(group II). We prospectively collected clinical data including risk factors and retrospectively reviewed the hospital resources. Result: Preoperative parameters including risk factors, postoperative mortality, morbidity and length of hospital stay were not different between the two groups, Duration of stay in the intensive care unit(ICU) (51.3 vs 128.3 hours, p<0.01) and ventilator, support time(14.9 vs 56.2 hours, p<0.01) were significantly shorter in the OPCAB group. Total hospital coats were 17,220,000 add 21,250,000(Korean Won) in group I and II, respectively(p<0.01). There were significant differences in operation fee, costs for operative materials, transfusion and diagnostic radiology between two groups. In group I, all the resources except diagnostic radiology were significantly decreased compared with group II. Conclusion: OPCAB has a beneficial effect on hospital charge and resource utilization. Shorter duration of the ICU stay and ventilatory support time may reduce the total hospital costs.

배경: 관상동맥우회술은 많은 비용이 소요되며 시술의 방법이나 질적 수준에 따라 환자의 생존율이나 진료비와 같은 진료결과에 큰 영향을 미칠 수 있다. 저자들은 체외순환 없는 관상동맥우회술과 전통적인 관상동맥우회술의 병원내 자원소모량을 비교함으로써 체외순환 없는 관상동맥우회 술의 경제적 측면에서의 유용성을 평가하고자 하였다. 재료 및 방법: 1998년 1월부터 1999년 7월까지 관상동맥우회술을 받은 184명을 대상으로 하였다. 이들 중 체외순환 없는 관상동맥우회술을 받은 환자(1군)은 111명이었고, 전통적인 관상동맥우회술을 받은 환자(2군)은 73명이었다. 환자의 진료결과 및 진료비에 영향을 미칠 수 있는 환자의 수술 전 위험요인과 병원 내 자원소모량을 조사하였다. 결과: 수술전 위험요인들의 분포와 술후 합병증의 발생율 및 술후 재원일수 등은 두 군간에 차이가 없었다. 하지만 두 군간의 중환자실 재원시간 (51.3$\pm$49.8 hr vs 128.3$\pm$150.2 hr; p<0.01)과 인공호흡기 사용시간 (14.9$\pm$22.7 hr vs 56.2$\pm$ 124.9 hr ; p<0.01)에는 유의한 차이가 있었다. 환자 본인 부담금과 의료보험공단 부담금을 합한 총 진료비는 1군이 1,722만 원, 2군이 7,125만 원으로 두 군간에 유의한 차이가 있었다(p<0.01). 항목별 진료비 중에서는 수술료, 재료대, 수혈료, 방사선검사료가 두 군간에 유의한 차이가 있었다. 1군에서 방사선검사료를 제외한 모든 항목별 진료비가 2군에 비하여 낮았다. 결론: 체외순환없는 관상동맥우회 술은 전통적인 수술법에 비해 저렴한 비용으로 우수한 효과를 얻을 수 있는 좋은 방법이다.
