  1. 1. HEALTH INFORMATICS By Jeff Maddox CIS 2010 JACK ZHENG SUMMER 2008 Health Care Information Systems Science
  2. 2. WHAT IS HEALTH INFORMATICS?  The study of the interrelationship between information, science, and medical research, practice & education.  The analysis and dissemination (dispersion) of medical data through computers to various aspects of health care and medicine.  A body of knowledge and a set of techniques used to organize & manage information in support of research, education and patient care.

  4. 4. HEALTH LEVEL 7 MESSAGING It is a communication tool used by multiple computers from a common network that allows all systems to interface with one another of changes in data stored on any of the computers connected to the network. These guidelines allow hospitals and organizations to share clinical information and alleviate geographical isolation of information.
  6. 6. DIGITAL IMAGING AND COMMUNICATIONS IN MEDICINE (DICOM) •It uses network communication protocols such as TCP/IP to communicate information between multiple systems in image form. •Integrates scanners, servers, printers & network hardware for image archiving by grouping information into data sets to prevent separation of data from the image (i.e. Clip art).
  8. 8. ELECTRONIC HEALTH RECORDS (E.H.R.) A longitudinal electronic record of patient health information generated by one or more encounters in any care delivery setting. Included in this information are patient demographics, progress notes, problems, medications, vital signs, past medical history, immunizations, laboratory data and radiology reports. The EHR automates and streamlines the clinician's workflow. The EHR has the ability to generate a complete record of a clinical patient encounter - as well as supporting other care-related activities directly or indirectly via interface - including evidence-based decision support, quality management, and outcomes reporting.
  9. 9. INFORMATICS SKILLS 1. Communicating effectively is based upon understanding cognitive models of information processing, and is constantly challenged by the limits of human attention, and the imperfection of models; 2. Structuring information, with a particular focus on the patient record, is shown to be dependent upon the task at hand, the channel used to communicate the message, and the agent who will receive the message; 3. Questioning others to find information is essential in clinical practice to fill the ever present gaps in every individual’s knowledge; 4. Searching for knowledge describes the broader strategic process of knowing where to ask questions, evaluating answers, and refining questions in the light of previous actions, and occurs in many different settings, from when patient’s are interviewed and examined, through to when treatment options are canvassed; 5. Making Decisions occurs when all the available information needed has been assembled using the other informatics skills, and attempts to come up with the best alternative to solve a problem like selecting a treatment, based both upon the evidence from science, as well as the wishes and needs of individuals.

  11. 11. CERTIFICATION COMMISSION FOR HEALTHCARE INFORMATION TECHNOLOGY (CCHIT) “The Certification Commission for Healthcare Information Technology or CCHIT is a recognized certification body (RCB) for electronic health records and their networks, and an independent, voluntary, private-sector initiative. It is our mission to accelerate the adoption of health information technology by creating an efficient, credible and sustainable certification program.”
  12. 12. IMIA: INTERNATIONAL MEDICAL INFORMATICS ASSOC. “There will be a world-wide systems approach for healthcare. Clinicians, researchers, patients and people in general will be supported by informatics tools, processes and behaviors that make it easy to do the right thing, in the right way, at the right time to improve health care for all. This systems approach will incorporate and integrate research, clinical care and public health. To achieve this vision it will require everyone being supported by informatics-based information and communication systems and technologies.”
  13. 13. CONSIDERABLE QUESTIONS  exchange of information between hospitals and admitting physicians;  exchange of information among hospitals within a community;  exchange of information between physicians and physician groups within a community;  exchange of information between patients and hospitals (such as availability of patient portals that enable access to personal health records);  exchange of information between patients and physician offices beyond lab results, e- mail and appointment scheduling;  exchange of information between health plans and patients; and  exchange of information between or among hospitals, physicians, pharmacies, nursing homes and home health care providers.
