Hospital Information Systems provide a common source of information about a patient’s health history.
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 information and visit history at the place and time that it is needed.
Patient’s laboratory test information also includes visual results such as X-ray, which may be reachable
by professionals. HIS provide internal and external communication among health care providers.

Clinicians collaborate with other health care and information technology professionals to develop health
informatics tools which promote patient care that is safe, efficient, effective, timely, patient-centered, and equitable. Many clinical informaticists are also computer scientists. Clinical informaticians, also known as clinical informaticists, transform health care by analyzing, designing, implementing, and evaluating information and communication systems that enhance individual and population health outcomes, improve care, and strengthen the clinician-patient relationship. Clinical informaticians use their knowledge of patient care combined with their understanding of informatics concepts, methods, and health informatics tools to:

  • Assess information and knowledge needs of health care professionals and patients.
  • Characterize, evaluate, and refine clinical processes.
  • Develop, implement, and refine clinical decision support systems.
