[Genetic counseling in Germany: development of demand]. / Humangenetische Beratung in Deutschland: Entwicklung der Inanspruchnahme.

ABSTRACT

BACKGROUND: With the Act on Genetic Testing (GenDG), the German legislator has issued far-reaching regulations for human genetic services, including genetic counseling. This paper presents data on the use of human genetic counseling in the years before and after the entry into force of GenDG in order to provide an informed assessment of the possible effects of the law. MATERIALS AND METHODS: Over a period of 13 years (2005 to 2017), the human genetic counseling services provided within the framework of the statutory health insurance and billable by EBM via the Kassenärztliche associations were recorded via a database query at the Central Institute of the National Association of Statutory Health Insurance Physicians (ZI-KBV) and via individual Kassenärztliche Vereinigungen Deutschlands. For the discussion of the observable development of using genetic counseling and possible future development, additional data on the referral behavior, the waiting times, processing time, and reasons for consultations were extracted from the GenBIn database. RESULTS AND DISCUSSION: Demand for genetic counseling has steadily increased at an average rate of approximately 6% per year since 2009. This increase started well before the enactment of the GenDG and may be attributed to a multiplicity of factors. Change in demand for genetic counseling is characterized by increasing self-referrals and by increasing referrals by specialists other than obstetricians/gynecologists. Waiting times between 2011 and 2016/2017 have increased. While demand has been growing, the number of key service providers, the contracted medical specialists in human genetics, has remained almost constant. It is foreseeable that capacity limits will be reached if both trends continue.
