An analysis of the demand for and cost of preimplantation genetic diagnosis in the United Kingdom.

Research in the field of preimplantation genetic diagnosis (PGD) has concentrated on increasing the number of diseases diagnosed, different strategies for single cell analysis and improving efficiency and reliability. Of equal importance are clinical issues such as the demand for and cost of PGD. This study assesses patient awareness of PGD and its potential benefits; additionally the awareness, attitudes and referral patterns of Assisted Conception Units, Regional Genetics Centres and Health Authorities (funding bodies) have been analysed to establish the demand for PGD within the United Kingdom. The licensed units are able to perform 128 cycles of PGD annually, however 256 cases were referred within the last year. It is clear that the currently licensed units operating at their present capacity are unable to meet the demand for PGD in the U.K. Concerns raised by this study include the unequal geographical distribution of PGD services and the lack of a uniform funding policy by Health Authorities. The investment in personnel and technology to establish a PGD service is considered and a costing provided. We estimate an initial investment in the region of 139,000 Pounds with annual running costs of 55,000 Pounds. This information should contribute towards an appropriate allocation of resources at a national level in the U.K.
