Decisional needs of patients considering preimplantation genetic testing: a systematic review

This systematic review reports on the needs and sources of support in patients' decision-making regarding the uptake of preimplantation genetic testing (PGT). Five databases were searched systematically to capture qualitative and quantitative studies. A total of 2336 studies were screened by title and abstract. Twelve studies met the eligibility criteria and reported on 4047 participants. This systematic review shows that patients need information directly relevant to PGT treatment, and information on health care relating to treatment and alternative reproductive options. Information that is too detailed, excessive and contains a large volume of medical terminology can be a barrier to decision-making. Published research suggests that health professionals provide general information on PGT and discuss it in detail only when patients require more information about it. Additionally, studies have shown that patients receive decisional support through mass media, significant persons in their lives and health professionals, whereas referring obstetricians and gynaecologists provided relatively less help compared with other health professionals. This systematic review highlights the importance of developing decision aids that meet patients' decisional needs as indicated in previous studies and that use innovative formats to deliver information. Additionally, given rapid technical developments, a dearth of continuing professional education is available on PGT for clinicians to keep updated.
