Ensuring Information Quality (June 2008)


Published on

Presented by Joe Gollner at Documentation and Training Life Sciences, June 23-26, 2008.

Information quality is always important. In the life sciences sector, however, information quality, or its absence, can be a matter of life and death. Even if poor quality information can be worked around, it is draining precious time and resources away from other activities that might improve the efficiency and effectiveness of the care being given. Fortunately, the movement towards digital healthcare information and services is happening at a time when there is a substantial body of knowledge and experience that has already been built up, typically within the contexts of other industries where information quality is critically important.

Among the most important of the lessons learned from past investments is the importance of leveraging intelligent automation to assist in the creation, management and delivery of high quality information resources and services. One of the areas of particular interest for the life sciences sector will be the role automation can play in validating content and facilitating the progressive elimination of errors and their sources. As has been illustrated, especially within the Aerospace and Defense sector, extraordinarily high levels of information quality can be achieved and sustained in ways that save time and money even when compared to activities that had been performed in order to meet far less exacting quality measures.

This presentation will introduce some of the background about the science of content validation and verification that is available to companies in the life sciences industry in its quest to achieve ever higher levels of quality.

  5. 5. Technology and Healthcare Primary focus has been on y improving the delivery of care Pharmaceuticals Medical devices Diagnostic support Secondary focus has been administrative Patients and staff Facilities F iliti Finance Persistent health information Has received less attention... Points towards larger “domains”
  6. 6. The Perils of Application Orientation Application Application Authoring Printing Application Printing Application Application Application Importing Indexing Viewing
  7. 7. The Nature of Software Applications Software Applications Applications are tools pp share a number of traits that amplify the skills of people to Developed to address a enhance performance Purpose specific purpose Predicated on data inputs Application with predictable structures and values Purpose Guided by “definitive” algorithms through which a result can be determined or Applications depend on Strict control Conditions Satisfied Fixed scope Limited timeframe
  8. 8. Extensible Markup Language (XML) Source: Microsoft
  9. 9. XML Filled a Growing Need Proprietary (controlled) formats and closed applications could not deal with growing complexity
  10. 10. XML: an Open Data Format for Open Systems
  11. 11. XML Enables Portable & Persistent Information XML is only one ( y (essential) ) part of the solution. XML alone does not guarantee portability portability, persistence or even XML usefulness. Multi-Format Multi Format Automatic Publishing Authoring ith A th i with Structured Markup
  12. 12. The Importance of Validation The rules governing documents have grown more sophisticated. Validity is in the eye of the consuming application...
  13. 13. The XML Revolution XML sought more than anything sought, anything, to enable content processability Wellformed XML primarily f publishing processes i il for bli hi Valid XML for more “data centric” processes The success of processable XML sparked a revolution in the way technology applications are t h l li ti designed, developed and deployed Adaptable components Service Oriented Architectures
  14. 14. Schema Protocols Content Instance The Tao of Validation XML Validation Content Verification The Grand Vision for Content Management & Processing Enabling the manufacture of interchangeable content components of exacting Transformation precision and durability Processing Outputs
  15. 15. Validate & Transform: Simple Content Validation Document Type Definition (DTD) structural rules Instance conformance Content Transformation Traditionally focused on arranging content for publishing formatted products Supporting primarily structural manipulation Validated Outputs V lid t d O t t Inputs to rendition processes typically for PDF outputs HTML outputs
  16. 16. Schema Rules Content Instance Validate & Transform: Complex Structure Validation Content Verification Content Validation & Verification Schema structural rules Rules governing content values Instance conformance Transformation Processing Content Transformation Continuous process of improvement Parse, validate, align, verify…repeat Manipulation of many content types Validated Outputs Outputs Inputs to rendition processes Multiple formatted outputs M lti l f tt d t t XML outputs Data outputs for applications

  19. 19. An Inevitable Evolution As the scope of a “solution domain” expands solution domain Content resources must become independent of any one application Application l (algorithms) A li ti rules ( l ith ) must b t become d dynamically adaptable i ll d t bl in order to deal with change and variability XML provides the essential format for both Content Rules This is important for large-scale considerations Public Health / Emergency Preparedness Improvement of “Patient Health” as well as specific “T t I t f “P ti t H lth” ll ifi “Treatments” t ” Addressing the growing complexity of the Healthcare enterprise
  20. 20. The Really Good News There has been 20 years+ experience built up in this field Best practices continue to evolve around validating & processing content Improving content quality Addressing technology challenges The XML revolution around us Can help facilitate new levels of coordination across the entire healthcare enterprise (Healthcare 2.0)
