Dimensions of Data Quality
Accessibility, Accuracy, Consistency, Comprehensiveness, Currency, Definition, Granularity, Relevancy, Precision, & Timeliness.
The purpose for which the data are collected.
The processes by which data elements are accumulated.
Processes and systems used to archive data and data journals.
The process of translating data into information utilized for an application.
Systematic Data Errors
Caused by a flaw or discrepancy in adherence to standard operating procedures or systems. Can also be casued by unclear data definitions or a failure to comply with the established data collection protocols, such as leaving out required information.
Random Data Errors
Caused by carelessness, lack of attention, or other one-time errors. Poor handwritting that results in an incorrect code would be an example.

AHIMA definition of Legal Health Record (LHR)
The documentation of the healthcare services provided to an individual in any aspect of healthcare delivery by a healthcare provider organization.
AHIMA Four Categories of Patient Data
– Legal Health Record
– Patient-Identifiable Source Data
– Administrative Data
– Derived Data
Protected Health Information (PHI)
– Relates to physical or mental health, provision of or payment for health care.
– Identifies the person.
– Created or received by a covered entity.
– Transmitted or maintained in any form.
HIPAA Privacy Rule Five Major Components
1. Boundaries
2. Security
3. Consumer Control
4. Accountability
5. Public Responsibility
PHI may be disclosed for health purposes only, with very limited excetions.
PHI should not be distributed without patient authorization, unless there is a clear basis for doing so, and the individuals who receive the information must safeguard it.
Consumer Control
Individuals are entitled to access and control their health records and are to be informed of the purposes for which information is being disclosed and used.
Entities that improperly handle PHI can be charged under criminal law and punished and are subject to civil recourse as well.
Public Responsibility
Individual interests must not override national priorities in public health, medical research, preventing health care fraud, and law enforcement in general.
Computer Software
Instructions that tell a computer what to do. Software is the entire set of programs, procedures, and routines associated with the operation of a computer system, including the operating system.
Programming Languages

Best of Breed (BOB)
Means using a specific software program or package for each specific application or requirement. These are selected based upon their ability to meet the organization’s specific needs better than any other available program. They may be from several vendors and may not be the low-cost package.

While the program does an excellent job in meeting the needs, it may not be able to communicate with other applications the organization is using.

To share information between the applications, the information is either printed out from one package and manually input in to the next or the packages are linked either by the vendor or using a third party “middleware” package or interface system.

Fully Integrated System (FIS)
A software package with a number of integrated modules or applications that cover a range of functions and requirements. Each application may not fully meet the needs of the organzation but workds well with the other applications from the vendor. This is also called a “Single Vendor Solution” or Monolithic Solution”

*Health Information Technology for Economic and Clinical Health Act (HITECH)
This act is a section of the $787 Billion American Recovery and Reinvestment Act of 2009 (Stimulus Package) which sets aside $19.2 Billion to encourage the adoption of Electronic Heatlh Records by physicians and hospitals.
Meaningul Use
Meaningful Use simply means that a healthcare organization employs its HIT software in a way that provides great value for the patient and other healthcare consumers while ensuring better quality and more efficiency for the provider.
Four Key Principles to Meaningful Use
1. Setting the right EHR goals.
2. Purchasing the right EHR product.
3. The right Implementation of the EHR.
4. The right Use of the EHR by caregivers.
Meaningulf Use Criteria for Providers
Improve the quality, safety, and efficiency of healthcare services
Reduce healthcare disparities
Engage the patients and their families
Improve the coordination of care
Improve population and public health
Ensure the privacy and security of PHI
Criteria and Certification requirements for EHR Software to meet
Securely exchange information among providers and between providers and patients
Standardized formats for reporting
Requirements for internet data exchange
Health Information Exchange
A system that facilitates the electronic movement of health-related information among organizations according to nationally recognized standards.

It consists of the technology, standards, and governance that enables the exchange of data between the disparate information systems of various healthcare providers.

The goal is to facilitate access to and retrieval of clinical data to provide safer, timelier, efficient, effective, equitable, patient-centered care.

Regional Health Information Organizations
The organizations that set up HIEs in a specific region and oversee and coordinate all the HIE activities in that area

Can operate in a city, multicounty, or even a complete state.

eHealth Exchange
Formerly known as the Nationwide Health Information Network (NwHIN)
Is a non-profit, public-private partnership that operationally supports the development of a nationwide system of HIEs that allow comprehensive access to patient health information.
Three Main Categories of Standards
Classification, Vocabulary, and Terminology Standards
Data Interchange Standards
Health Record Content Standards
Ad Hoc Standards of Development Process
A standard is established by the ad hoc method when a group of interested people or organizations agrees on certain specifications, without any formal adoption process.
De Facto Standards of Development Process
Arises when a vendor or other commercial enterprise controls such a large segment of the market that its product becomes the recognized norm.
Government Mandate Standards of Development Process
Standards are also established when the government mandates that the health care industry adopt them.
Standards come about when representatives from various interested groups come together to reach a formal agreement on specifications. The process is generally open and involves considering comment and feedback from the industry.
International Organization for Standardization (ISO)
Members are national standards bodies from many countries
ANSI is the US national body member
Oversees the flow of documentation and international approval of standards developed by its member bodies
American National Standards Institute (ANSI)
US member of ISO
Accredits SDOs from a wide range of industries (including health care)

Problems of Poor Quality Data
– Pt. Care
– Communication among providers & pt’s
– Documentation
– Reimbursement
– Outcomes Assessment
– Research
5 Major Functions negatively affected by poor-quality documentation
– Pt Safety
– Public Safety
– Continuity of Pt Care
– Health Care Economics
– Clinical Research & Outcomes
Medical Record Institute Principles of Health Care Documentation
– Unique Patient Identification within and across systems
– Health care documentation must be
Accurate & consistent
Interoperable across systems
– Confidential and secure authentication and accountability must be provided
Data Accuracy
Data that reflect correct, valid values are accurate. Typographical errors in discharge summaries and misspelled names are examples of inaccurate data.
Data accessiblity
Data that are not available to the decision makers needing them are of no use.
Data comprehensiveness
All of the data required for a particular use must be present and available to the user. Even relevant data may not be useful when they are incomplete.
Data consistency
Use of an abbreviation that has two different meanings. For example, a nurse may use the abbreviation CPR to mean cardio-pulmonary resuscitation at one time and use it to mean computer-based patient record at another time, leading to confusion.
Data Currency
Many types of healthcare data become obsolete after a period of time. A pt’s admitting diagnosis is often not the same as the diagnosis recorded at discharge. If a health care executive needs to report on the diagnoses treated during a particular time frame, which of these two diagnoses should be included?
Data definition
Must be provided so that both current and future data users will understand what the data mean. One way is to use data dictionaries.
Data granularity
Sometimes referred to as data atomicity. That is, individual data elements are “atomic” in the sense that they cannot be further subdivided. For example, a typical pt’s name should generally be stored as three data elements (last name, first name, middle name) not as a single data element.

Related to the purpose for which the data are collected. Although it is possible to subdivide a person’s birth date into spearate fields for the month, the date, and the year, this is usually not desirable.

Values should be defined at the correct level for thier use.

Data relevancy
Data must be relevant to the purpose for which they are collected. We could collect very accurate, timely data about a pt’s color preferences or choice of hairdresser, but is this relevant to the care of the pt.
Data timeliness
A critical dimension in the quality of many types of health care data. Producing accurate results after the pt has been discharged may be or little or no value to the pt’s care.
