Using a unit assessment tool to optimize patient flow and staffing in a community hospital

Hospital environments are too often characterized by delays for patients receiving diagnostic testing and prolonged waiting times to complete needed therapy. Frequently there is confusion in scheduling, related at least in part to the complex interplay of clinical acuity and highly individualized care. Luther Midelfort recently began to change the process of patient flow to improve access to care, optimize outcomes by enabling timely intervention, and decrease the wasting of resources.

The hospital developed a unit assessment tool based on the traffic light concept, which consisted of an assessment of current capacity and a graded, color-coded "workload tolerance" for each hospital unit. Each unit can instantly update its own status and query those of other work environments in the hospital.

For most of the January-July 2001 period, there was generally a progressive decrease in the percentage of time that the units were coded as red (unit closed to new admissions), with concurrent increases in the percentage of time that the units were coded as green (unit open). Use of the tool appears to have contributed to a dramatic increase in staff satisfaction.

The key to regulating patient flow has been to adopt a nursing-initiated capping trust policy whereby nurses are given the authority to limit new admissions. Initiatives are now under way to provide different units with novel models of resource sharing, ranging from flexible housekeeping to "flying nurse squads" to assist units that have become red.
