In general computer systems are far superior at restricting access to information than manual systems. With computerisation, an opportunity is provided whereby sensitive information can be made available strictly on a need to know basis. All computerisation in the hospital services to date has incorporated this feature. In the past, stringent security measures were implemented where personal information was concerned and particularly in the case of medical records; this will continue to be the case. Furthermore, the Data Protection Act places particular responsibilities in relation to confidentiality of personal information on all agencies processing such information by computer.
