Group project slides of informatics infrastructure (1)
What is informatics? Informatics is “the science and art of turning data into information.” (Hebda, 2013).
The building blocks of an informaticsinfrastructure are: Standardized terminologies and structures Digital sources of evidence Standards that facilitate healthcare data exchange Informatics processes that support the acquisition and application of evidence to a specific clinical situation Informatics competencies (Bakken, 2001). Let’s look at each of these in more detail.
Standardized terminologies and structures “Structured and controlled languages that have been developed according to terminology development guidelines and have been approved by an authoritative body.” (Hebda, 2013). This allows for information sharing between different applications. “The adoption of EHRs implemented with standardized terminology is proving to be a positive effect on the improvement of healthcare quality, efficiency, and patient safety.” (U.S. Department of Health and Human Services, 2009).
Data exchange standards Support the communication among computer- based systems to bring together patient data and decision logic. Facilitate the delivery of tailored health-related messages based on patient-specific data. Support aggregation of data across time and geography to link process to outcomes (Bakken 2001). In the past, data retrieval was primarily performed for use within a single institution. Changes in the healthcare delivery system now mandate exchange of client information between institutions (Hebda 2013)
Data exchange standards Health Level Seven International (HL7), an ANSI- accredited (standards developing organization (SDO), is the global authority on standards for interoperability of health information technology. HL7 does not develop software. It creates standards that allow healthcare information to be communicated across and between healthcare enterprises and communities. HL7 standards facilitate the exchange of clinical and administrative data among health information systems (Health Level Seven International 2007-2012).
Data exchange standards HL7 provides a comprehensive framework and related standards for the exchange, integration, sharing, and retrieval of electronic health information that supports clinical practice and the management, delivery, and evaluation of health services (Health Level Seven International 2007-2012).
Informatics processes that support theacquisition and application of evidence to aspecific clinical situation Integrate and link heterogeneous sources of evidence. Present clinician alerts related to potential adverse events. Use decision analytic techniques to tailor evidence to specific patients. Perform data modeling and aggregation in clinical data repositories. Perform data mining (Bakken 2001).
