Improving user experience of POC...

Point of care (POC) touch screen wall mounted data capture systems are being used by many long term care facilities (LTC) across the country as an efficient means for nursing assistants / CNAs / STNAs to enter in information on vitals and other daily care updates after they give daily care and assist their patients.  Reports indicate an improved user experience when the screens are larger than a standard computer screen (at least 24 inches by 30 inches).  When mounted at a reasonable height with a height adjuster arm, these POC screens can enable CNAs to capture the data on a patient's vitals and ADLs right away, instead of having them jot the information down on paper, for the nurse to add to the EHR later.  This latter model allows for too much time to go by before nurses and other clinical staff are alerted to a potential health complication.  Many LTC facilities have only a few screen monitors, and they are typically mounted in the common hallway for easy access.  Privacy can be an issue, as CNAs are entering data in public spaces on large boards. Timed logout for inactivity, as well as easy ways to log in and out aid in improving usability and the over all user experience.  Additionally, screen privacy protector elements can be added (so that passers-by cannot see the information from the side)...and have been successful at allowing the CNA to enter data freely without compromising privacy.   These devices can help make a difference in patient care, but how long will these be relevant?  What further changes can you recommend on improving the user experience of this health IT device to improve patient care?  Will these devices become more prevalent?  Will they be health IT of the past?
