Development and implementation of a human accuracy program in patient foodservice.

Area of Science:

• Healthcare Management
• Food Service Operations
• Quality Improvement

Background:

• Industry has long used human error rates to monitor and minimize errors.
• Consistent quality control enhances consumer satisfaction and product loyalty.
• Administrative dietitians sought to apply human error rate concepts in hospital food service.

Purpose of the Study:

• To evaluate the impact of human error rates on trayline employee performance.
• To assess the effectiveness of trayline station layout and tasks.
• To monitor and improve patient service areas through error rate analysis.

Main Methods:

• Human error rates (errors/opportunities for error) were applied in four hospitals (788 beds).
• Trayline employee performance, station layout, and patient service areas were evaluated.
• Employee feedback and patient satisfaction surveys were utilized.

Main Results:

• Average daily error rates decreased from 7% to 3% in facilities with new employees.
• Error rates increased in facilities with long-term employees, indicating documentation issues.
• Patient satisfaction with tray accuracy increased from 88% to 92% in long-term employee facilities and remained above 90% in new employee facilities.

Conclusions:

• Human error rate monitoring enhances employee self-esteem and productivity through feedback.
• The system effectively improved tray accuracy and patient satisfaction in hospital food services.
• Careful error documentation is crucial for accurate performance evaluation, especially with experienced staff.
