DNA-based genetic testing is rising steeply in a national health care system with open access to services: a survey of genetic test use in Germany, 1996-2002.
The extent to which the fast-growing body of genetic knowledge is transferred into everyday clinical practice has nowhere been assessed in a systematic way. Available quantitative analyses of DNA-based genetic test provision and uptake rates are all concerned with specific test programs. The German health-care system is ideally suited for a more general approach, because it is highly flexible regarding access to services, thus permitting quick adjustments to sudden changes in particular subfields of medicine such as genetic testing. We have measured the amount of genetic service provision in Germany between 1996 and 2002 by making use of the central database of the German national health-care system and by inquiring with private health insurance. We can document a three-fold increase of DNA-based testing in the time period 1996-2002, whereas cytogenetic analyses and genetic counseling have remained constant. The growing body of genetic knowledge does indeed seem to be transferred into medical practice at an increasing rate, and the uptake rates are largely in proportion to test offers. DNA-based testing appears to be focussed on disease-associated germ-line alterations.
