Question

You will find various IT systems across different health care settings. In a 750- to 1,050-word paper, describe how the systems work together to provide useful information for the provider.

Include an explanation of both clinical and administrative data systems in addition to how those systems support activities such as patient and payer billing, patient scheduling, clinical orders and results, and other key interoperable activities.

Include an explanation of how individual and aggregated patient data is exchanged across systems within the organization as well as to payers and government reporting bodies.

Answer 1

In modern health care system,health care informatics has grown as an evolving science with the expansion of electronic health records(EHRs) and health data analytics systems.Health informatics is the practice of acquiring,studying and managing health data and applying medical concepts in conjunction with health information technology systems to help clinicians provide better health care.It has also grown with the establishment of health data exchange standards such as HL7(Health level seven international) and fast health interoperability resources(FHIR). HL7 is a set of standards,formats and definitions for exchanging and developing EHRs.FHIR is an interoperability standard for electronic exchange of Heath care.

Clinical informatics is used in direct patient care by supplying physicians,nurses,physical therapists,aides and other caregivers with information that can be used to develop a care plan.Clinical informatics helps to analyse data or medical images to help clinicians to retrieve that information.They can also develop interfaces to health IT systems.The field has became more important as most healthcare givers more easily view and use health data.Nursing informatics is another kind of health informatics that encompasses nurses interaction with health IT systems.This field has become more important as most health care systems and physicians practice facilities have put their patient records online and entrust their nursing teams to handle transition of care situations in their EHRs.Nursing informatics specialists try to accurately document transitions of care .As with clinical informatics nursing informatics is still become an educational field in which students can get academic degrees,certificates also.

The director of medical informatics is the chief medical information officer(CMIO).Those people are responsible for designing and integrating technology into physicians works flows and they straddle the medical and technological sides of medicine and serving as an intermediaries between physicians and the IT department.Chief nursing information officeris also there,The duties of them are also overlap with those of a CMIO.The Chief nursing information officers role is mainly focussed on evaluating products and developing a workflow within which nursing teams can be effectively use the technology they most commonly work with the electronic health care system.

According to American medical information association public health informatics include the application of computer science,information and technology to the administration of public health that includes disease surveillance,prevention,preparedness and health education.Public health informatics heps in taking decisions about public health policies and programmes such as clinical data registries and chronic disease prevention.some universiities and schools offer courses in Health informatics in Degree and PG level.

Health Informatics are also incresinly using technologies such as machine learning to perform predictive analytics about the likelyhood of individual patients and larger patient populations getting certain diseases as well as their outlook for treatment.In the area of date interchange,standards are needed for message format,document artitecture ,clinical templates,user interface and patient data linkage.Message format standards facilitate interoperability through the use of common encoding specifications,information models for defining relationship between data elements,document artitectures and clinical templates for structuring data as they are exchanged.There are currently three key forms of health information exchange.The data is exchanged through direct exchange,querry based excange and consumer mediated exchange .
