The Simplified Therapeutic Intervention Scoring System TISS-28 consists of 28 items. It is intended to accurately measure the level of care required for a patient in the Intensive Care Unit (ICU) but be simpler to administer than previous TISS forms. It correlates well with the TISS-76 score and can be used in its place.
Parameter |

Points |
basic activities |
standard monitoring (hourly vital signs, calculation of fluid balance, regular registration) |

3 |
ventilatory support |
[2] mechanical ventilation (any form of mechanical or assisted ventilation with or without PEE), with or without muscle relaxants; spontaneous breathing with PEEP) |
5 |
|

|
treatment for improving lung function (thorax physiotherapy, incentive spirometry, inhalation therapy) |
1 |
cardiovascular support |
[3] single vasoactive medication (any vasoactive drug) |
3 |
|
[3] multiple vasoactive medications (more than1 vasoactive drug) |
4 |
|
intravenous replacement of large fluid losses; fluid replacement > 3 liters per square meter per day; disregard type of fluid administered |
4 |
|
peripheral arterial catheter |
5 |
|
left atrium monitoring; pulmonary artery flotation catheter with or without cardiac output measurement |
8 |
|
central venous line |
2 |
|
cardiopulmonary resuscitation after arrest in the past 24 hours (a single precordial percussion not included) |
3 |
renal support |
hemofiltration techniques. Dialytic techniques |
3 |
|
quantitative urine output measurement |
2 |
|
active diuresis |
3 |
neurologic support |
measurement of intracranial pressure |
4 |
metabolic support |
treatment of complicated metabolic acidosis/alkalosis |
4 |
|
intravenous hyperalimentation |
3 |
|
enteral feeding (through gastric tube or other GI route such as jejunostomy) |
2 |
specific interventions |
[4] single specific intervention |
3 |
|
[4] multiple specific interventions |
5 |
|
specific interventions outside of ICU (surgery, diagnostic procedures) |
5 |
where:
• The selection of one item marked [1], [2], [3] and [4] excludes the other matching numbered item.
• single specific interventions = naso- or oro-tracheal intubation, introduction of a pacemaker, cardioversion, endoscopies, emergency surgery in the past 24 hours, and gastric lavage.
TISS-28 =
= SUM(points for actions involved in the care of the patient)
estimated the TISS-76 =
= ((TISS28) - 3.33) / 0.97
Interpretation:
• minimum score = 0 (unlikely in patient requiring true intensive care)
• maximum score = 78
• Each nurse is capable of providing care for 46.35 TISS-28 points per shift. Each TISS-28 point requires 10.6 minutes of each nurse's shift.
