  • Title: A comparison of workload estimates using three methods of patient classification.
    Author: O'Brien-Pallas L, Leatt P, Deber R, Till J.
    Journal: Can J Nurs Adm; 1989; 2(3):16-23. PubMed ID: 2486682.
    Abstract:
    This research examined the equivalence of the workload estimates of three commonly used patient classification systems in nursing (GRASP, PRN and Medicus). Patient classification systems are used for program costing and formulation of the nursing budgets. The findings suggest that the estimates of absolute hours of care provided by the three systems differ significantly when all three tools are used on the same patient population, particularly in the Intensive Care Units (ICUs). The data suggest that these differences result from the weights assigned to individual indicators within each system. Although hours of care estimates are significantly different, they are highly correlated. This research suggests that the estimates of hours and costs provided by different patient classification systems may involve clinically important differences. These discrepancies could result in inequitable funding practices unless mechanisms are developed for showing the relationships between systems.
