Standards for confidentiality, privacy, access, and data security.

The American Society for Testing and Materials (ASTM), an accredited standards development organization with a focus on health care informatics, has recently produced a standards document on the principles of confidentiality, privacy, access, and data security. The ASTM subcommittee responsible for this work is ASTM 31.17. The article discusses the link between voluntary health informatics standards and issues such as confidentiality and data security in computerized health information systems.

Preparing physicians for a computer-based patient record system.

The Providence experience provides a model which encompasses both preparation for a computer-based patient record and a physician-oriented approach to achieving quality documentation for the physician component of the patient record. The study comparing Providence to a similar medical center demonstrated the value of the new system in achieving quality patient records. Many hospitals in the Seattle area, including Overlake, now use this system or variations of it.

Clinical correlates of small area variations in population-based admission rates for diabetes.

To verify and elucidate the results of a previous study that documented four-fold variations in small area admission rates for diabetes mellitus in Washington state, the authors examined the hospital records of a sample of diabetes discharges from hospitals in high-, medium-, and low-rate counties. Hospitals in high-rate counties were generally smaller than those in medium- and low-rate counties and admitted a greater proportion of patients with mild illness. Also, physicians in hospitals in high-rate counties tended to be less vigorous in the diagnosis and treatment of diabetes. Variations in admission rates were not explained by coding errors or by differences in selected sociodemographic characteristics of admitted patients. The authors conclude that small area variations in hospitalization rates for diabetes were related to clinical differences in admission criteria and may also reflect differences in the medical management of hospitalized patients.

Ambiguities in the selection of the principal diagnosis: impact on data quality, hospital statistics and DRGs.

A statewide stratified, random sample of diabetes-related hospital discharges for Medicare and Medicaid recipients was reviewed to assess principal diagnosis coding validity. After reabstracting, only 60 percent of the sample were found to be unequivocally correct. In another 23 percent, the correct principal diagnosis could not be determined with certainty. Furthermore, ten percent of the cases where diabetes mellitus was coded as another diagnosis were ambiguous as to whether diabetes actually was the principal diagnosis. The potential impacts of these ambiguities on measures of admission rates, average length of stay, and hospital payment are examined.
