  1. Chapter 3 Ensuring the Quality and Best Use of Information

  2. Data Management • Process of controlling the collection, storage, retrieval, and use of data to optimize accuracy and utility while safeguarding integrity • Also known as business intelligence (BI)

  3. How can we make the right decision without good data management?

  4. Data Management Levels • Data entry level • System analysts • help identify data needed and collection • Method of collection • Programmers • create computer instructions that collect required data • build the database

  5. Data Management levels • Database administrator (DBA) • oversees details of maintaining and using database • Optimizing the use of the database

  6. Data Warehouse • Repository for storing data from several different databases so that it can be combined and manipulated to provide answers to complex analytic questions

  7. Data Storage • Online storage • Provides access to current data • Rapid, using high-speed hard disk drives or storage space on the network • Virtual drives • Offline storage • For data that are needed less frequently, or for long-term data storage of old client records • Can be done on any secondary storage device • CDs, DVDs, External HD,

  8. Data Storage Considerations • Speed/frequency of access needed • Virtual drive vs. DVD • Environmental conditions and hazards • Temp., water, fire, magnetic fields • Control of equipment and media • Logical restriction • Physical restrictions • Contingency planning • Backup copy

  9. Data Storage Considerations • Storage period for each record type • Patient info should be stored for certain minimum length • Media degradation • DVD may degrade after few years, transfer data in case longer storage required • Obsolescence of hardware and software • Rapid advance in technology threaten the use of old tech. Eg. Floppy disk

  10. Outsourcing • Process by which an organization contracts with outside agencies for services • Must consider costs • Personnel • Space • Equipment • Maintenance • Expertise

  11. Data Retrieval • Process that allows the user to access previously collected, stored data • Considerations • Performance response: the ability of the system to respond to the user’s request • Capacity—amount of data that can be stored and retrieved • Security—protected against unauthorized access • Cost: hardware, software, personnel

  12. Data Exchange • Growing expectation that information collected in one facility will be available to another • E.g. a patient may have surgery in once center but have a follow up appointment at a satellite location

  13. Data Mining • Technique that uses software to look for hidden patterns and relationships in large groups of data • E.g. in business used to identify the customers interest and marketing trends

  14. Data Cleansing • Procedure that uses software to improve the quality of data to ensure that it is accurate enough for use in data mining and warehousing • Used to fix inconsistent entries, duplicate entries • Typos, misspelling

  15. Data Disposal • Physical destruction • Secure disposal of documents containing PHI • Shredding • Deform/destroy storage media • Software destruction • Overwrite data

  16. Chch. Of Quality information • Timely: insurance info available immediately at a follow up visit • Precise: abdominal surgery vs. specific name of the surgery • Accurate: left vs right below knee amputation • Numerically quantifiable: stage of ucler, cancer

  17. Quality information • Rapidly and easily available: pt in ER, allergies can be quickly retrieved from EMR past history • Comprehensive: info about med include name dosage, frequency • Clear: patient don’t like eggs vs. allergy from eggs • Current: regular update

  18. Threats to information quality • Alteration of files • Accidental or intentional change of data • System alteration • Adding of new function may result in data loss • Viruses, Trojans, worms • Damage, steal info

  19. Threats to information availability • Destruction of hardware or software, or even data • Natural or manmade • Interruption of power • Loss of power  loss of data • Denial of service • Malicious software overwhelm a website  access denied • Sabotage • Intentional destruction of harware, software or data

  20. Threats to confidentiality • Failure to adhere to information policies • Misuse of computer access • Eavesdropping • Unauthorized access to info • Looing at the system data • Improper handling of confidential data • Unauthorized reception of wireless network technology transmissions
