Changes in structure may affect outcome after intensive care in various ways. Both closed (as opposed to open) units and the number of nurses have been shown to affect outcome.
To study the effects of temporarily moving an intensive care unit (ICU) on various indicators of outcome and quality of care.
Because of rebuilding, over a period of 8 months our ICU was moved to an adjacent postoperative area. The 12 month periods immediately before and after the rebuilding were chosen as reference periods. Routinely collected data such as length of stay, ventilator time, readmission rate, severity score (SAPS II), and observed mortality were used for comparison.
Using variable life adjusted display (VLAD), an increase in hospital mortality was observed during the 8 month rebuilding period. This was also found using Kaplan-Meier estimates of survival and standardised mortality ratio.
Structural change to our ICU was probably the major cause for the observed change in mortality.
结构变化可能以多种方式影响重症监护后的结果。已表明封闭式(与开放式相对)病房和护士数量会影响结果。
研究重症监护病房(ICU)临时搬迁对各种结果指标和护理质量的影响。
由于重建,我们的ICU在8个月的时间里搬到了相邻的术后区域。重建前后的12个月期间被选为参考期。使用常规收集的数据,如住院时间、呼吸机使用时间、再入院率、严重程度评分(简化急性生理学评分II [SAPS II])和观察到的死亡率进行比较。
使用可变寿命调整显示(VLAD),在8个月的重建期间观察到医院死亡率增加。使用Kaplan-Meier生存估计和标准化死亡率也发现了这一点。
我们ICU的结构变化可能是观察到的死亡率变化的主要原因。
