Info-NAS: A Computer Program for the Calculation of Intensive Care Unit Nurse Workload.

The purpose of this study was to design an algorithm that allows automatic calculation of nursing workload in intensive care units, based on the Nursing Activities Score scale, through a computer program. Three methodological steps were used: (1) Delphi method (group of experts); (2) identification of the correspondence: Nursing Activities Score items-variables in the EHR, namely, standardized terminology, laboratory values, and prescriptions; and (3) weighting of variables independently by a group of experts. Finally, the algorithm of the computer program was tested.
