A modification of the original TISS was developed for patients in non-ICU settings such as intermediate ("step-down") and regular nursing units. This can be used both to quantitate the severity of patient illness and to measure the nursing workload.
Items relative to original TISS:
(1) retained, with same point score (49)
(2) retained, but reweighted (10)
(3) new (26)
(4) deleted (18)
Scoring: Points are scored if the modality was used within the previous 24 hours, except for a new tracheostomy or acute digitalization (48 hours).

where:
• separation into subgroups is not in the original table, which merely separated interventions by point scores (Table 2, page 1409, Cullen et al, 1994)
• items in brackets "[ ]" appear to be mutually exclusive (my choice)
• I am not sure what an "arterial sheath" refers to
• formal chest "physiology" may refer to physiotherapy (as in original TISS)
Deleted items from original TISS (18):
• controlled ventilation with intermittent or continuous muscle relaxants
• balloon tamponade of varices
• pulmonary artery catheter
• induced hypothermia
• G suit
• intracranial pressure monitoring
• intra-aortic balloon assist
• intermittent mandatory ventilation or assisted ventilation
• measurement of cardiac output by any means
• active therapy of metabolic alkalosis
• active therapy of metabolic acidosis
• phlebotomy for volume overload
• coverage with > 2 IV antibiotics
• hourly neuro vital signs
• vasopressin infusion
• decubitus ulcer
• STAT blood tests (weighted 1 point; 3 point intervention retained)
• extensive irrigation, packings or debridement of wounds, fistula or colostomy
intermediate TISS =
= SUM [ therapeutic interventions being used]
The intermediate TISS results in the test patients showed good correlation with the original TISS results, with a linear relation.
intermediate TISS =
= 4.4 + (1.4 * (original TISS))
This can be rearranged:
original TISS =
= ((intermediate TISS) - 4.4) / 1.4
