 4-South Irving, the experimental unit, will be used as its own control. A second unit, 6S, will maintain current practices and data from this unit will be used to determine if there are any hospital-wide fluctuations for fall rates, patient satisfaction, or call light usage. Age, gender, and severity of illness of subjects on the control and experimental units will be compared. Because the patient populations differ from the experimental to control unit, the reasons why patients use the call light will be collected to verify that these two groups use the call lights for similar reasons.
