The Therapeutic Intervention Scoring System (TISS) is a method of quantifying over a 24 hrs period, nursing and medical care required by ICU patients.
A "locally modified" version of the 1983 TISS76 with a list of 83 therapeutic variables has been used at Health Sciences Center (HSC) since July, 1988. This version was also implemented in all other ICU's within the Winnipeg Regional Health Authority (WRHA) since 1999.

Purpose
- TISS is utilized worldwide for many purposes:
- Establishing nurse-patient ratios in the ICU
- Assessing current utilization of ICU beds
- Establishing future needs and numbers of ICU beds
- Expresses work activities in statistical terms.
- Determining severity of illness (NOTE: this capability of TISS has lost its application with the appearance of more specific scoring systems in the 1980 namely APACHE).
- TISS has been incorporated as an integral part of the Acute Physiologic and Chronic Health Evaluation APACHE II
- The comparative scores of TISS and APACHE enables us to see trends in the type of nursing care (TISS) provided for certain acuity levels (APACHE), for a specific type of diagnosis.
- Reviewing both scores can help determine whether certain nursing activities can be redirected or standardized in certain types of critically ill patients without affecting patient mortality or morbidity.
History
- TISS has become a widely accepted and validated method of classifying critically ill patients.
- First introduced in 1974 by Cullen DJ, Civetta JM, Briggs BA, et al: Therapeutic scoring systems: A method of quantitative comparison of patient care. Crit Care Med 2:57-60, 1974) at the Massachusetts General Hospital. (TISS with 70 therapeutic variables).
- Modified in 1983. (TISS with 76 therapeutic variables) TISS76-Points

- Modified version in 1994 for use for intermediate and floor care nursing units (iTISS).
- Modified version in 1996. TISS28 included 28 therapeutic variables. File:TISS 28 R.Miranda CritCareMed1996.pdf
