Transcript of Medical Information Systems

Integrating the Healthcare Enterprise Improves how computer systems in healthcare share information Promotes coordinated use
of established standards
HL7 IHE-developed systems enable:
better communication
easier implementation
effective use of information
Cross-Enterprise Document Sharing (XDS)
Patient Identifier Cross-referencing (PIX)
Patient Demographics Query (PDQ)
Audit Trail and Node Authentication (ATNA)
Consistent Time (CT)
Enterprise User Authentication (EUA)
Retrieve Information for Display (RID)
Patient Synchronized Applications (PSA)
Personnel White Pages (PWP)

IHE IT Infrastructure Technical Framework Definitions Medical record or chart A systematic documentation of a patient’s medical history and care
Medication Licensed drug taken to cure or reduce symptoms of an illness or medical condition
Electronic health record (EHR)
Real time patient health record with access
to evidence-based decision support tolls that
can be used to aid decision-making
Computerized Provider Order Entry (CPOE)
A computer application that allows for the electronic entry of a physician’s order for diagnostic treatment services.
Health information and data
Results management
Orders management
Decision support
Electronic communications and connectivity
Patient support
Administrative process
EHR Capabilities Goal: Develop a standards-based registry prototype that will allow healthcare professionals to find and access all pertinent documents of clinical information regarding a patient regardless of the healthcare organization that creates and manages the documents.
standardizing metadata
adherence to security and privacy policies
indexing documents
Vision for consumer-centric and information rich care Medical information follows consumer
Information tools guide medical decisions
Clinicians have appropriate access to patient's complete medical history
CPOEs used to:
order medicines and procedures
eliminate errors
prevent harmful interactions
issue electronic alerts
research and compare
To Do List
Goal 1 Goal 2 Goal 3 Goal 4 Inform clinical practice Interconnect physicians Personalize care Improve population health Establish a Health Information Technology Leadership panel

Acquire private sector certification of health information technology products

Fund community health information exchange demonstrations

Plan and form a private interoperability consortium

Require standards to facilitate electronic prescribing

Commit to those standards!
The most complex enterprise in modern society from an organizational standpoint Transport Level Data Level Process Level "We have the tools to begin a major transformation in American health care made possible through the creation of a secure, interoperable nationwide health information system...it provides the best opportunity for each patient to receive optimal care." - David Blumenthal, M.D., M.P.P.   National Coordinator for Health Information Technology
Provides the infrastructure and abstraction over the communication protocols needed to move data between similar and dissimilar entities in a transparent manner. (SOAP)
Facilitates integration of business applications by addressing the representation data elements in different systems and associated transformation rules. (XML)
Pertains to the integration of at least two different entities. (Web services)
Complete, accurate, and searchable health information, available at the point of diagnosis and care
More efficient and convenient delivery of care
Earlier diagnosis and characterization of disease, with the potential to thereby improve outcomes and reduce costs.
Reductions in adverse events through an improved understanding of each patient’s particular medical history.
Increased efficiencies related to administrative tasks, allowing for more interaction with and transfer of information to patients, caregivers, and clinical care coordinators and monitoring of patient care
Ultimate Outcomes Where to Start Medical Information Systems are... Let's Learn About... What is IHE? Medical Information Systems Important pieces of the IHE Framework...
