It is widely acknowledged that it will be desirable and necessary for non specialist health professionals to become involved in enabling wider access to genetic information so that patients can make informed choices and decisions (eg Kinmonth et al. 1998). It is not always recognised that to ensure accessibility and utilization of the information requires more than just a reasonable genetic knowledge base on the part of the professional. Attitude and counselling skills and the time to use them will also be necessary, as well as an alertness to the need to refer on when required. The Confidential Enquiry into Counselling for Genetic Disorders by non geneticists indicated that much practice fell short of what was required (Harris, R & H. 1999).
The increasing development of genetic susceptibility testing, particularly for some cancers, being drawn to the attention the public by media coverage is leading to increased expectations and anxiety. The public do have problems with the concept of having 'a gene' but not necessarily having a disease problem. Professionals need a breadth and depth of genetic knowledge ensure the correct diagnosis has been reached, to assess the appropriateness or limitations of testing and the time and skills to share that with their patients, for, properly used, genotype information has great potential for guiding management . One study reports that 32% of physicians who had ordered a test (for FAP) had misinterpreted the results and 20% of patients did not have a valid reason for having the test in the first place (Giardiello F, et al. 1997.)
This re-forces the need for much greater emphasis on education and training in genetics and counselling skills and available resource to address this.

Marteau et al. (1992) gives a good starting point for considering the utility of genetic information and tests - 'No matter how good a test is technically, screening of uninformed unsupported patients by unprepared staff is a recipe for at best confusion and at worst, great distress. And it is avoidable. We should be recommending how.

Within Clinical Genetic Services there is great care, based upon current knowledge, attitude, expertise and experience, in delivering genetic information within a framework which addresses the patient agenda and context. Counselling skills are used to explore the motivation of the patient enquiry and assess the psychological and social elements which may indicate a risk of a negative outcome. This comprehensive approach will need to be embraced by any health professional delivering elements of a genetic service. The need for facilitating informed choice with full consent applies whether we are talking about single gene disorders eg carrier testing population antenatal testing eg serum screening for Downs or susceptibility testing eg for some cancers.

It is clear that considerable resource will need to be spent on both education of other professionals and on creating service delivery frameworks which allow the time for proper exploration of available options if informed choices are to be enabled. Two examples of implementation of screening programmes without the necessary education and resource to ensure optimum for patients can be cited in the Downs screening programme and neonatal screening for CF. In both situations professionals have not shown a mastery of either the information or the skills to prevent negative outcomes for patients who have been left confused and anxious.
