Evaluation of the simplified therapeutic intervention scoring system: Chinese version

Objective: To prepare the Simplified Therapeutic Intervention Scoring System (TISS-28) to measure nursing workload in Intensive Care Units in Guangdong Province of China. Methods: A non-experimental descriptive study was conducted in the intensive care units in the Province. TISS-28, TISS-76, Acute Physiology and Chronic Health Evaluation (APACHE II) were all measured. Results: There were significant positive correlations between TISS-28 and APACHE II (n = 91, r = 0.432, p < 0.001), TISS-76 scores (n = 83, r = 0.764, p < 0.001). A significant difference was found between the mean TISS-28 score in the first day of the intensive care stay and the last day (30.76 +/- 6.86 vs 24.67 +/- 5.48, p < 0.001). A significant intra-class correlation was found between TISS-28 scores collected by the researcher and research associates (ICC = 0.959, p < 0.001). Conclusion: The reliability and validity of TISS-28 were shown in Chinese intensive care units. It is a practical tool for estimating the nursing workload and providing opportunities to compare the data between intensive care units in different facilities. The TISS-28 Chinese version is recommended to guide the allocation of nursing manpower in Chinese intensive care units. (C) 2017 Elsevier Ltd. All rights reserved.
