HIM professionals use _____________ to locate articles on HIM issues as well as articles on medical topics necessary to carry out quality improvement and medical research activities

The DBMS data dictionary

developed in con-junction with development of a specific database. Modern DBMS's have built-in data dictionaries that go beyond data definitions and store information about tables and data relationships. These integrated data dictionaries are sometimes referred to as system catalogs, reflecting their technical nature.

the organi-zation-wide data dictionary

developed outside the framework of a specific database design pro-cess. This data dictionary serves to promote data quality through data consistency across the orga-nization. Individual data element definitions are agreed upon and defined. This leads to better qual-ity data and facilitates the detailed, technical data dictionaries that are integrated with the databases themselves. This ___________ document becomes a valuable resource for IS development.

Cancer registries

facility-based registry (located within a facility such as a hospital or clinic) or a population-based registry (gathering information from more than one facility within a geographic area such as a state or region).

Secondary data sources consist of

facility-specific indexes; registries, either facility or population based; and other healthcare databases.

An index

is simply a report from a database that enables health records to be located by diagnosis, procedure, or physician.

National Practitioner Data Bank (NPDB)

mandated under the Health Care Quality Improve-ment Act of 1986 to provide a database of medical malpractice payments; adverse licensure actions including revocations, suspensions, reprimands, censures, probations, and surrenders of licenses for quality-of-care purposes only; and certain pro-fessional review actions (such as denial of medical staff privileges) taken by healthcare entities such as hospitals against physicians, dentists, and other healthcare providers

Access permissions: Define and enforce access to data. Data dictionary: A data dictionary exists and each data element is defined. The definitions are communicated to all staff. Standardized format: Use a standardized format to ensure consistency. State and federal laws: All laws, regulations, ac-creditation standards, and policies are followed. Data Integrity: Implement policies and pro-cedures throughout the patient encounter to ensure data integrity

The master patient index (MPI),

Also known as the master person index, contains pa-tient-identifiable data such as name, address, date of birth, dates of hospitalizations or encounters, name of attending physician, and health record number.

Disease Index

Always includes the patient's health record num-ber as well as the diagnosis codes so that records can be retrieved by diagnosis. Because each patient is listed with the health record number, the _________________ is considered patient-identifiable data. The ________________also may include other information such as the attending physician's name or the date of discharge.

The National Nursing Home Survey

schema mapping

ERDs are converted into tables by a process called:

In the disease index

Each patient's diagnoses are converted from a verbal description to a numerical code, usu-ally using a coding system such as the Internation-al Classification of Diseases (ICD).

Evaluate trends in disease outbreaks. State and local public health departments also develop databases as needed to perform their duties of health surveillance, disease prevention, and research. An example of a state database is the infectious and notifiable disease database. The ___________which serves as a major part of the Public Health Information Network (PHIN). It provides a national surveil-lance system by connecting the CDC with local and state public health partners. This integrated system allows the CDC to monit

External users of patient data

individuals and institutions outside the facility like state data banks and federal agencies

Relational databases

most widely used in numerous industries, including healthcare. This model consists of a database with a set of formally described tables, related (linked) to each other by a shared reference. It is widely used because it offers a simple, yet powerful view of stored information. Devel-opers can easily understand how information is organized and users can create their own interac-tive queries. It is flexible enough that databases can be simple or complex, and yet each part has an easy to understand representation.

Healthcare organizations

must establish data quality standards specific to the intended use of the data or resulting information.

The data collected also may provide comparisons in survival rates and quality of life for patients with different treat-ments and at different stages of cancer at the time of diagnosis. In population-based registries, em-phasis is on identifying trends and changes in the incidence (new cases) of cancer within the area covered by the registry.

provides a way to integrate biomedical concepts from a variety of sources to show their rela-tionships. This process allows links to be made between different information systems for pur-poses such as the electronic health record. __________ is of particular interest to the HIM professional because medical classifications such as ICD-10-CM, CPT, and the Healthcare Common Proce-dure Coding System (HCPCS) are among the items included.
