Moving out of the red zone: addressing staff allocation to improve patient satisfaction.
BACKGROUND
Each summer, Hermann Hospital (Houston), like virtually all health care organizations, faces staffing challenges because of employee vacations, increased patient load, and staff turnover. A "zone" system was developed to address staff allocation, which was identified as a factor in deterioration of the hospital's patient satisfaction performance. ZONE SYSTEM: Every day, each unit or department designated the zone most appropriate based on factors identified in root cause analysis--high patient census, high patient acuity, emergent activity, and the number of float, agency, or unfamiliar staff members. A green zone defines conditions where the staff is very comfortable; yellow reflects increased activity; and red indicates that staff members are stressed and overwhelmed with patient needs.
Management's action steps included decreasing the nursing vacancy rate to minimize reliance on agency and float staff members and securing longer-term commitments from temporary staff members. Individual units also generated contingency plans, such as identifying a "partner unit" to provide shared staff members, supplies, and other assistance.


RESULTS
The percentage of patients rating their overall experience at Hermann Hospital as "good" or "excellent" increased from 83% in August 1997 to 89% in August 1998, despite increases in admissions, patient days, operating room cases, and emergency department visits.


CONCLUSIONS
The zone system provides a rapid way to quantify contributing factors to patient dissatisfaction and respond to them. Hermann Hospital is currently developing a broader zone system to include staff vacancy rates by departments, areas of increased patient census for prolonged periods, and balancing episodic zones with prolonged zones.
