The hospital information system has become an integral part of health care. It is linked to the health informatics that focuses mainly on the administrative functioning of hospitals and clinics. It is a comprehensive information system designed to deliver every administrative operation in the healthcare industry.
Hospital information systems in recent years have evolved into digital systems involving computers, instead of using older methods, such as filing cabinets and paper. A computerized health information system is made up of steps such as data input, processing, outputs, and boundary. The computer system receives the health data, which then get processed to finally produce the specified outputs, and there are predefined boundaries to influence the outputs.
The aspect of processing involves monitoring as well as memory functions. The digitized health informatics system is associated with the idea of a wide range of aspects. For instance, the healthcare organizations, the medical professionals, and the mortuary are part of the health system. All these systems comprise a clearly defined boundary. As an example, you can consider that the grocery shop cannot be a part of the health care system.
The input, processing, and output changes with the purpose of a system and it is usually felt that certain system models can be based on the input aspects, which will eventually influence the processing and output. However, the design of most information systems is based on the outputs.
Within a hospital organisation it will contain non-technical aspects of Security. A hospital will have problems such as employee risk and personnel Security. Some examples of Employee Risk could be Human Error, Fraud, Misuse of sensitive information and sabotage.
Human error can be a big problem within a big organisation such as a hospital. Any hospital will have a lot of people working there and will have a lot of problems when humans are involved.
A human could enter data wrong or could forget something important. Humans make mistakes and sometimes this must be considered as it can potentially be a problem but sometimes can’t be controlled. There are ways to mitigate against human error though. Some countermeasures to mitigate against these problems could be:
§ Provide a clear definition and structure of authority
You must make a record of who is responsible for what and where it is. A hierarchal system must put into place to keep track on which people must be put in charge of what.
§ Ensure any type of fraudulent behaviour requires collaboration
This makes sure there must be two members of staff present when anything that could be tampered with is taking place.
§ Rotate People within roles and responsibilities
Rotating roles and responsibilities will make sure the same person can’t make the same mistake repeatedly.
