A<unk>  (HIS) is an element of health informatics that focuses mainly on the administrational needs of<unk> s. In many implementations, a HIS is a comprehensive, integrated<unk>  system designed to manage all the aspects of a<unk> 's operation, such as medical, administrative, financial, and legal issues and the corresponding processing of services.<unk>  is also known as<unk>  management software (HMS) or<unk>  management system.<unk> s provide a common source of<unk>  about a patient's health history, and doctors schedule timing. The system has to keep data in a secure place and controls who can reach the data in certain circumstances. These systems enhance the ability of health care professionals to coordinate care by providing a patient's health<unk>  and visit history at the place and time that it is needed. Patient's laboratory test<unk>  also includes visual results such as X-ray, which may be reachable by professionals. HIS provide internal and external communication among health care providers. Portable devices such as smartphones and tablet computers may be used at the bedside.<unk> s are often composed of one or several software components with specialty-specific extensions, as well as of a large variety of sub-systems in medical specialties from a multi-vendor market. Specialized implementations name for example laboratory<unk>  system (LIS), Policy and Procedure Management System, radiology<unk>  system (RIS) or picture archiving and communication system (PACS). Potential benefits of<unk> s include: *Efficient and accurate administration of finance, diet of patient, engineering, and distribution of medical aid. It helps to view a broad picture of<unk>  growth *Improved monitoring of drug usage, and study of effectiveness. This leads to the reduction of adverse drug interactions while promoting more appropriate pharmaceutical utilization. *Enhances<unk>  integrity, reduces transcription errors, and reduces duplication of<unk>  entries.<unk>  software is easy to use and eliminates error caused by handwriting. New technology computer systems give perfect performance to pull up<unk>  from server or cloud servers.
