Abstract

A system determines patient acuity information to identify required staff competencies to meet a workload and supports role based reporting, notification, and escalation when acuity nears or reaches a predetermined saturation threshold. A system predicts healthcare worker workload using an acquisition processor to acquire multiple data items associated with care requirements of a particular patient from multiple different sources. A data processor determines an acuity score of the particular patient by determining a single score comprising a combination of weighted individual score values derived from corresponding individual items of the multiple data items. A translation processor interprets determined acuity score to provide an estimated healthcare worker workload for meeting the care requirements of the particular patient by using predetermined translation data associating acuity score with corresponding healthcare worker workload.
