Annual reports from Norwegian Intensive Care Units include risk-adjusted mortality data. Annual variation may be difficult to interpret due to random variation and changes in case mix. Several methods have been developed for continuous monitoring of treatment results in clinical practices where it is possible to calculate a risk for a certain outcome, usually risk of death. We have used the cumulative risk adjusted mortality chart Variable Life Adjusted Display (VLAD) to further illustrate our treatment results.
3190 patients were treated in our intensive care unit during the period 1997-2006. 2777 of these patients were given scores for risk of death during hospitalization and the treatment result (as risk-adjusted mortality) was calculated.
The risk-adjusted mortality varied from year to year with a tendency for better survival the last years. Variation in mortality was clearly demonstrated by the Variable Life Adjusted Display (VLAD) curve.
The VLAD curve is a very useful supplement to traditional methods of evaluating the performance of intensive care units. The method is useful for showing how treatment results vary over time.
挪威重症监护病房的年度报告包含风险调整后的死亡率数据。由于随机变异和病例组合的变化，年度差异可能难以解释。在临床实践中，当可以计算特定结局（通常是死亡风险）的风险时，已经开发了几种方法用于持续监测治疗结果。我们使用累积风险调整死亡率图表可变寿命调整显示（VLAD）来进一步说明我们的治疗结果。
1997年至2006年期间，我们的重症监护病房共治疗了3190例患者。其中2777例患者在住院期间被给予死亡风险评分，并计算治疗结果（作为风险调整后的死亡率）。
风险调整后的死亡率逐年变化，最近几年有生存改善的趋势。可变寿命调整显示（VLAD）曲线清楚地显示了死亡率的变化。
VLAD曲线是评估重症监护病房绩效的传统方法的非常有用的补充。该方法有助于显示治疗结果如何随时间变化。
