Yourtown General Hospital is concerned about the prevalence of nurses failing to log

out of work computers, leaving patient information vulnerable to passersby and

creating a HIPAA violation. Human Resources has developed a training program to

educate nurses about the importance of always logging out of all programs whenever

they step away from a device. The training program is implemented for all nurses

currently working in the orthopedics unit of Yourtown General. After the training

program is complete, the nurses are asked to anonymously answer "yes" or "no" to the

question: do you understand the importance of logging out of the computer whenever

you leave a work station? Additionally, for one month after the completion of the

training, the number of nurse logouts is tallied. During this month, the nurses in the

orthopedic unit logged out of hospital devices an average of 1874 times each. During

the month before the training, the nurses in the orthopedics unit had logged out of

hospital devices an average of 1608 times.
