To evaluate the performance of the Simplified Therapeutic Intervention Scoring System on an independent database and determine its relation with the Therapeutic Intervention Scoring System in the quantification of nursing workload in intensive care.
Analysis of the database of a multicenter prospective Portuguese study.
19 intensive care units (ICUs) in Portugal.
Data on 1094 patients consecutively admitted to the ICUs were collected during a period of 3 months.
Collection of the data necessary for the calculation of the Therapeutic Intervention Scoring System (TISS-76) and the Simplified Therapeutic Intervention Scoring System (TISS-28) during the first 24 h in the ICU. Basic demographic statistics and all the variables necessary for the computation of the Simplified Acute Physiology Score II were also collected. Vital status at discharge from the hospital was registered. Regression techniques, Pearson's correlation and paired sample t-test were used. Results are presented as mean +/- standard deviation except when stated otherwise. Reliability was evaluated by the use of intraclass correlation coefficients in a 5% random sample.
After exclusion of all the patients with missing data, 1080 patients were analysed. The overall mean TISS-28 (29.82 +/- 10.64) was significantly lower than the mean TISS-76 (31.14 +/- 11.95). Both systems showed very significant differences between ICUs (p < 0.001). The correlation between the two was good, with TISS-28 explaining 72% of the variation of TISS-76 (r = 0.85, r2 = 0.72). The relation between the two systems was TISS-28 = 6.22 + 0.85 TISS-76. In this cohort, reliability of data collection was very high, with intraclass correlation coefficients greater than 0.90 for both systems.
TISS-28 was validated on this independent population. The results indicate that TISS-28 can replace TISS-76 for the measurement of the nursing workload in Portuguese ICUs.
在一个独立数据库中评估简化治疗干预评分系统的性能，并确定其在重症监护护理工作量量化方面与治疗干预评分系统的关系。
对一项多中心前瞻性葡萄牙研究的数据库进行分析。
葡萄牙的19个重症监护病房（ICU）。
在3个月期间收集了1094例连续入住ICU患者的数据。
在ICU的最初24小时内收集计算治疗干预评分系统（TISS - 76）和简化治疗干预评分系统（TISS - 28）所需的数据。还收集了基本人口统计学统计数据以及计算简化急性生理学评分II所需的所有变量。记录患者出院时的生命状态。使用回归技术、Pearson相关性和配对样本t检验。结果以均值±标准差表示，除非另有说明。通过在5%的随机样本中使用组内相关系数评估可靠性。
排除所有有缺失数据的患者后，对1080例患者进行了分析。TISS - 28的总体均值（29.82±10.64）显著低于TISS - 76的均值（31.14±11.95）。两个系统在不同ICU之间均显示出非常显著的差异（p < 0.001）。两者之间的相关性良好，TISS - 28解释了TISS - 76变异的72%（r = 0.85，r2 = 0.72）。两个系统之间存在的关系为TISS - 28 = 6.22 + 0.85TISS - 76。在该队列中，数据收集的可靠性非常高，两个系统的组内相关系数均大于0.90。
TISS - 28在这个独立人群中得到了验证。结果表明，在葡萄牙的ICU中，TISS - 28可替代TISS - 76用于测量护理工作量。
