The Health Insurance Portability & Accountability Act and the practice of dentistry in the United States: system security.

This article reviews the issues related to the Health Insurance Portability & Accountability Act (HIPAA) security rule that apply to dental practice. The security rule specifically addresses individually identifiable health information that is transmitted or maintained in electronic media. System security must be applied to the entire technical infrastructure for the practice environment as well as to the work culture on a daily basis and must be thought of as an enterprise asset.

The Health Insurance Portability and Accountability Act and the practice of dentistry in the United States: electronic transactions.

This article reviews the kinds of electronic transactions required under the Health Insurance Portability & Accountability Act (HIPAA) and relates them to relevant data contained in an electronic oral health record (EOHR). It also outlines the structure of HIPAA transactions using the claim transaction as an example. The relationship of the HIPAA resource management function to those of patient care are discussed.

LOINC, a universal standard for identifying laboratory observations: a 5-year update.

The Logical Observation Identifier Names and Codes (LOINC) database provides a universal code system for reporting laboratory and other clinical observations. Its purpose is to identify observations in electronic messages such as Health Level Seven (HL7) observation messages, so that when hospitals, health maintenance organizations, pharmaceutical manufacturers, researchers, and public health departments receive such messages from multiple sources, they can automatically file the results in the right slots of their medical records, research, and/or public health systems. For each observation, the database includes a code (of which 25 000 are laboratory test observations), a long formal name, a "short" 30-character name, and synonyms.

The Health Insurance Portability and Accountability Act: practice of dentistry in the United States: privacy and confidentiality.

This paper introduces the reader to the Health Insurance Portability and Accountability Act (HIPAA) of 1996 legislation in the context of its relationship to the Electronic Oral Health Record (EOHR). Privacy and confidentiality issues for administrative data are addressed in terms of the broader relationship of such data to the EOHR leaving the HIPAA-defined administrative transactions and security issues for the entire practice for a subsequent presentation. Educational requirements are presented that aid the dentist and the practice staff in understanding the broad and long-term implications of the HIPAA legislation.

The electronic oral health record.

This paper presents the history of the use of the computer for maintaining patient medical care information. An electronic record generated with a computer, which is non-specific for any healthcare specialty, is referred to as the electronic health record. The electronic health record was previously called the computer-based patient record.

Development of the Logical Observation Identifier Names and Codes (LOINC) vocabulary.

The LOINC (Logical Observation Identifier Names and Codes) vocabulary is a set of more than 10,000 names and codes developed for use as observation identifiers in standardized messages exchanged between clinical computer systems. The goal of the study was to create universal names and codes for clinical observations that could be used by all clinical information systems. The LOINC names are structured to facilitate rapid matching, either automated or manual, between local vocabularies and the universal LOINC codes.

Logical observation identifier names and codes (LOINC) database: a public use set of codes and names for electronic reporting of clinical laboratory test results.

Many laboratories use electronic message standards to transmit results to their clients. If all laboratories used the same "universal" set of test identifiers, electronic transmission of results would be greatly simplified. The Logical Observation Identifier Names and Codes (LOINC) database aims to be such a code system, covering at least 98% of the average laboratory's tests.

Medical nomenclature and common conventions for trauma registries.

A trauma registry has been created containing lexicons of terms arranged to foster the adoption of standardized and extensible terminology for the nature and mode of injury. Identification of attribute sets for the nature-of-injury (body region:detailed part:type of injury) and for the mode-of-injury (mechanism:agent:activity:intent:setting) allows the assembly of a clear, concise, easily usable, nad extensible format for representing the appropriate level of detail for nomenclature or classification. This ability allows the use of a common list of terms that is adaptable for case records used in patient care as well as in trauma registry statistics.

Implementation of attractive dialogues in nutritive analysis and clinical dietetics information systems.

The implementation and evaluation of a system providing both extensive nutritive-analysis calculations and interactive capabilities are described. The extensive calculating ability of the system arose from the historic need for nutrient intake estimates in clinical investigation and nutritional research. The availability of computer-aided instruction (CAI) system software lead to adoption of the interactive style originating at Ohio State University.

Information and clinical pharmacology: role of the computer.

The author notes the need for information from a variety of sources in order to support decision processes of the clinical pharmacologist. One of the data-bases urgently required is a central collection of drug information, which includes quantitative pharmacokinetic data as well as qualitative data and which would be used in evaluating complex drug interactions as well as uncomplicated adverse reactions. The need to be able to link these data-bases with others is noted.

Human factor IX in animals: kinetics from isolated, radiolabelled protein and platelet destruction following crude concentrate infusions.

Crude, concentrated and isolated, labelled human factor IX was prepared and infused into animals. Initially, two dogs with severe haemophilia B received both preparations and factor IX clotting activity and label survived well. Kinetic parameters fit a two-compartment open model.

Pharmacokinetics of amikacin in patients with normal or impaired renal function: radioenzymatic acetylation assay.

The acetylating radioenzymatic assay was used for determination of levels of amikacin in serum and urine. Because of an inhibitor present in various amounts in urine, assay of amikacin in urine by this method requires added internal standards and thus is less precise than the assay in serum. Determination of the rate of plasma clearance, half-life, and volume of distribution of amikacin in 10 patients with normal renal function, four patients undergoing dialysis, and five patients with end-stage renal diseases have shown a relation of half-life (t1/2 in hr) to rate of clearance of serum creatinine (Cer) of t1/2 = 3 X Cer, the same relation as found for kanamycin and gentamicin.

Assay of flucytosine and furosemide by high-pressure liquid chromatography.

A high-pressure liquid chromatographic method for the analysis of flucytosine and furosemide concentrations in biological fluid is described. The separations were carried out on a pellicular cation-exchange resin eluted with an ammonium phosphate buffer. Detection of elution peaks was by UV absorption at 280 nm and fluorescence monitoring.
