Abstract

Objective

The length of hospital stay (LOS) allows for the evaluation of the efficiency of a given hospital facility, as well as providing a basis for measuring the number of hospital beds required to provide assistance to the population in a specific area.

Methods

A retrospective survey was conducted on a database of 3,010 patients submitted to coronary artery bypass graft (CABG) from July, 2009 to July, 2010.

Results

Among 2,840 patients that met the inclusion criteria, 92.1% had their surgery paid by the Brazilian Unified Health System (Sistema Único de Saúde - SUS) and 7.9% by health plans or themselves (non-SUS). 70.2% were male, the average age was 61.9 years old, and the average risk score (EuroScore) was 2.9%. The SUS and the non-SUS groups did not differ regarding the waiting time for surgery (WTS) (2.59 ± 3.10 vs. 3.02 ± 3.70 days for SUS and non-SUS respectively; p = 0.790), but did differ with respect to the length of stay in intensive care unit (2.17 ± 3.84 vs. 2.52 ± 2.72 days for SUS and non-SUS respectively; p < 0.001), the postoperative period (8.34 ± 10.32 vs. 9.19 ± 6.97 days for SUS and non-SUS respectively; p < 0.001), and the total LOS (10.93 ± 11.08 vs. 12.21 ± 8.20 days for SUS and non-SUS respectively; p < 0.001). The non-SUS group had more events of non-elective surgery (p = 0.002) and surgery without cardiopulmonary bypass (p = 0.012). The groups did not differ regarding the associated valve procedure (p = 0.057) nor other non-valve procedures (p = 0.053), but they did differ with respect to associated non-cardiac procedures (p = 0.017). ICU readmission (p = 0.636) and postoperative complications rates were similar in both groups (p = 0.055).

Conclusion

The Non-SUS group showed longer LOS compared to the SUS group.

支付者冠状动脉旁路移植术住院时间的评价
目的住院时间(LOS)可用于评估特定医院设施的效率,并为衡量向特定地区的人口提供援助所需的医院病床数量提供基础。方法对2009年7月至2010年7月行冠状动脉旁路移植术(CABG)的3010例患者进行回顾性调查。结果2840例符合纳入标准的患者中,92.1%的患者手术费用由巴西统一卫生系统(Sistema Único de Saúde -SUS)支付,7.9%的患者手术费用由健康计划或自己支付(非SUS)。男性占70.2%,平均年龄61.9岁,平均风险评分(EuroScore)为2.9%。SUS组与非SUS组在手术等待时间(WTS)方面无差异(分别为2.59±3.10天和3.02±3.70天);p = 0.790),但在重症监护病房的住院时间方面存在差异(SUS组和非SUS组分别为2.17±3.84天和2.52±2.72天;p & lt;0.001), SUS组和非SUS组的术后时间分别为8.34±10.32天和9.19±6.97天;p & lt;0.001),总生存期分别为(10.93±11.08 vs. 12.21±8.20)天;p & lt;0.001)。非sus组有更多的非选择性手术事件(p = 0.002)和无体外循环手术(p = 0.012)。两组在相关瓣膜手术(p = 0.057)和其他非瓣膜手术(p = 0.053)方面没有差异,但在相关非心脏手术方面存在差异(p = 0.017)。两组ICU再入院率(p = 0.636)及术后并发症发生率相似(p = 0.055)。结论非SUS组的LOS较SUS组长。
