관상동맥우회로술(CABG)환자의 재원일수와 병원 내 사망률 변이에 대한 경피적관상동맥성형술(PTCA)과 소아심장수술(PHS)의 영향분석
A Study on the Effects of Percutaneous Transluminal Coronary Angioplasty and Pediatric Heart Surgery on the Differences of Risk-Adjusted Length of Stay and In-Hospital Death for Coronary Artery Bypass Graft Patients
The purpose of this study was to analyze the differences in the outcome for CABG according to whether hospitals provided heart related surgeries. The 2011 National Inpatient Sample (NIS) and inpatient quality indicator principles from the Healthcare Research and Quality (AHRQ) were used for analysis. Hospitals were divided into three groups according to the surgeries they provided. The length of stay and in-hospital deaths were adjusted for the differences in risks. ANOVA was performed to examine the differences for the risk-adjusted in-hospital mortality rate and risk-adjusted length of stay among the three groups. The analysis results showed that hospitals providing CABG, PTCA, and PHS had lower risk-adjusted in-hospital mortality rates or similar risk-adjusted lengths of stay compared to those of hospitals providing only CABG. However, the three groups did not have statistically significant differences in outcome indicators. Another study will be needed with a larger sample.
