Point-Of-Service Systems
Uses handheld or bedside PC
Ensure that data are entered @ the point where they are collected
POS are installed in ICU
Problems before POS:
Costly to record twice
There are certain amount of error whenever data are transcribed from one place to another
Greater chance that scrap sheet will be lost/misplaced
If the scrap sheet is lost, there is a potential for compromised patient confidentiality
There is a delay between the time data are collected and the time those data are show up on the chart
The remote work station approach virtually guarantees idle nursing time because only one person can use the workstation at  a time, and  there is always competition for access to the workstations.
