A system is provided for communicating to health care workers the turning, positioning and schedule requirements of dependent patients with pressure ulcers, or at risk for the development of pressure ulcers. The system includes a display indicating a next required position of the patient and a display indicating a time for next movement of the patient to the next position. The time of next movement is calculated by entering an indication of a maximum allowable time for the patient to remain in each position and adding this to the current time.
