A scoring system based on therapeutic intervention on critically ill patients called the therapeutic intervention scoring system (TISS) was used to assess the quantity of care provided in a medical intensive care unit. Besides observing the unit census, the severity of illness and the work load were studied. The survival rate was 77 percent. The non-survivors had admission TISS points higher than the survivors and their mean daily TISS was more than 20 points. The survivors at discharge had a mean TISS of five points. The work load showed that a nurse can effectively manage two patients who together may accumulate 24 TISS points per day. TISS points per patient rather than bed occupancy is a better indicator of the nurse's work load. Admission criteria and procedures before death certification are outlined.
