Physician and nursing (personnel) requirements for ICUs. Therapeutic Intervention Scoring System (TISS) versus time requirements for patient care--a comparative study in an interdisciplinary surgical intensive care unit.
OBJECTIVE
To measure total physician manoeuvres and total nursing manoeuvres in intensive care patients and to compare the results with calculated personnel requirements on the basis of TISS scores.


METHODS
Open prospective study.


METHODS
Sixty-three ICU patients on two consecutive days.


METHODS
1. Total physician activities (TPM) in minutes/patient-day; total nursing manoeuvres (TNM) in min/patient-day. 2. TISS Calculation of personnel requirements on the basis of both parameters.


RESULTS
TPM averaged at 3.9 hours.  No fixed correlation was established between TISS and TPM.  TNM averaged 1,073 minutes/patient-day and demonstrated a good correlation with TISS.


CONCLUSIONS
Physician activities on a surgical ICU averaged 3.9 hours/patient-day.  Nursing manoeuvres average 17.9 hours/patient-day.  Individual measurements must be made before calculating personnel requirements on the basis of TISS scores.
