These guidelines must be assimilated by the information system, not only to provide information to the individual physician or nurse on what these guidelines are, but for what reasons these guidelines are being breached. Common Health Care Provider Specifications Critical Care concerns in general are very similar to the concerns of physicians and nurses looking after patients on general medical and surgical wards. These concerns are for the reliability of data, security, and confidentiality. Our project in the Coronary Care Unit has already identified that much of the data entry is haphazard, inaccurate, or insufficient. Databases must be supervised and monitored for accuracy and completeness.
Security is also another area of concern.
There are many threats to an information system that take the form of viruses, inaccurate data entry, and trespassing by the unwanted hacker. The system must have a defense against these threats. A proper balance must be found and maintained to achieve good security and have ease of use. The aforementioned categories give both the users and designers many benefits. The first is that the modular characteristics of the system will support expansion due to increasing use, as well as reduce maintenance and support costs.
