Abstract
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. The results showed an algorithm that calculates the nursing workload in an ICU. The calculation is objective and automatic through the EHRs. This study shows the feasibility of the algorithm as a rapid and objective strategy to quantify adequate nurse staffing in intensive care units. Moreover, it provides nurses with a practical resource for the correct completion of records and is thus an incentive to maintain or improve their quality.
