Description

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

Action

Points

basic activities

standard monitoring (hourly vital signs, calculation of fluid balance, regular registration)

5

 

laboratory investigations

1

 

[1] single medication, any route (IV, po, IM, etc.)

2

 

[1] multiple intravenous medications (more than 1 drug, single injections, or continuously)

3

 

routine dressing changes (care and prevention of decubitus and daily dressing change)

1

 

frequent dressing changes (at least one time per nursing shift and/or extensive wound care)

1

 

care of drains (all except gastric tube)

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

 

[2] supplementary ventilatory support (breathing spontaneously through endotracheal tube without PEEP; supplementary oxygen by any method except if mechanical ventilation used)

2

 

care of artificial airways (endotracheal tube or tracheostoma)

1

 

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.
