Health care data security: one size does not fit all.

In the wake of the Internet, E-commerce, and particularly the Health Insurance Portability and Accountability Act, data security has risen to the top of health care information technology priorities. What is the correct mix of data security tools, policies, and technologies for the doctor, the hospital, the insurer, the vendor, and everyone else who does business in the health care industry?

Communication security in open health care networks.

Fulfilling the shared care paradigm, health care networks providing open systems' interoperability in health care are needed. Such communicating and co-operating health information systems, dealing with sensitive personal medical information across organisational, regional, national or even international boundaries, require appropriate security solutions. Based on the generic security model, within the European MEDSEC project an open approach for secure EDI like HL7, EDIFACT, XDT or XML has been developed. The consideration includes both securing the message in an unsecure network and the transport of the unprotected information via secure channels (SSL, TLS etc.). Regarding EDI, an open and widely usable security solution has been specified and practically implemented for the examples of secure mailing and secure file transfer (FTP) via wrapping the sensitive information expressed by the corresponding protocols. The results are currently prepared for standardisation.

Utilization management in a mixed-payment environment.

Fee-for-service and capitation payment methods create different financial incentives for healthcare providers, and the objectives of utilization management differ under each payment method. These differences can be reconciled, however, by incorporating the strengths of utilization management programs associated with both methods into an overarching program that focuses on the continuum of care. Such a program should be focused on achieving the optimal outcomes for patients by identifying the appropriate level of care, who should provide it, and when and where it should be provided. Essential to this effort is access to comprehensive clinical and financial data through an integrated information system. In addition, financial incentives need to be aligned through such means as risk pools, compensation arrangements tied to achievement of medical management goals, and clearly defined policies and procedures.

Comparison and contrast of affinity chromatographic determinations of plasma glycated albumin and total glycated plasma protein.

Techniques for affinity measurement of glycated albumin and for glycated total plasma protein have been developed. The two techniques were contrasted. Both techniques are linear over a 100-fold range of sample concentrations. There appears to be a non-specific early glucose binding phase to non-albumin plasma proteins. Although this phase is detected by radioactive incorporation and thiobarbituric acid, it does not interfere with the affinity determination, which does not appear to detect the early binding species. The correlation of glycated albumin levels with glycated hemoglobin levels is much stronger than that of glycated globulin levels with glycated hemoglobin levels. Due to the large contribution of glycated albumin levels to total glycated serum protein levels, the correlation of the latter with glycated hemoglobin levels is sufficiently strong to allow the use of either technique as an adequate index of glycation.
