Because of the increasing role of post-anaesthesia care in anaesthetic activity, the explicative value of various factors on post-anaesthesia length of stay (POLS) was tested.
Retrospective study.
Population of 38,655 patients admitted to the post-anaesthesia care unit (PACU) between 1990 and 1994.
Multivariate analysis (semiparametric Cox model) of POLS.
Overall 71% of the patients stayed less than four hours in PACU. Average POLS did not vary with years. Eleven variables were related to POLS, with an odds-ratio (OR) between 0.75 and 0.77 (negative link) or between 1.22 and 2.77 (positive link). A comparison of the OR for years 1990 to 1994 indicated major variations for the following three variables: neurosurgery, mechanical ventilation in PACU, low occupancy rate in the PACU at the time of discharge.
POLS are linked with various factors whose changes in explicative value can be analysed chronologically. However, other methods remain necessary in order to evaluate the impact of organisational modifications, as the introduction of objective criteria for discharge.
由于麻醉后护理在麻醉活动中的作用日益增加，因此对影响麻醉后住院时间（POLS）的各种因素的解释价值进行了测试。
回顾性研究。
1990年至1994年间入住麻醉后护理单元（PACU）的38655名患者。
对POLS进行多变量分析（半参数Cox模型）。
总体而言，71%的患者在PACU停留时间少于4小时。平均POLS并未随年份变化。11个变量与POLS相关，优势比（OR）在0.75至0.77之间（负相关）或在1.22至2.77之间（正相关）。对1990年至1994年的OR进行比较表明，以下三个变量有重大变化：神经外科手术、PACU中的机械通气、出院时PACU的低占用率。
POLS与各种因素相关，其解释价值的变化可以按时间顺序进行分析。然而，为了评估组织变革的影响，如引入出院客观标准，仍需要其他方法。
