Insights
Most parents of children with sickle cell disease (SCD) are unaware of preimplantation genetic testing (PGT). Education significantly increased awareness and interest in PGT as a reproductive option.
Area of Science:
- Genetics
- Reproductive Medicine
- Hematology
Background:
- Sickle cell disease (SCD) is a genetic blood disorder affecting millions worldwide.
- Preimplantation genetic testing (PGT) offers a way to screen embryos for genetic conditions before implantation.
- Awareness of PGT for SCD among affected families is not well understood.
Purpose of the Study:
- To assess parental awareness and attitudes towards PGT for SCD.
- To evaluate the impact of educational interventions on PGT knowledge and perception.
Main Methods:
- A cohort of parents with children diagnosed with SCD received an educational handbook on PGT.
- Anonymous surveys were administered post-clinic visit to gauge awareness and attitudes.
- Data analysis included descriptive statistics of survey responses.
Main Results:
- Only 24% of parents were previously aware of PGT for SCD.
- Post-education, 97% deemed PGT information important for parents of children with SCD.
- 91% of parents interested in future pregnancies would consider PGT if insurance covered it.
Conclusions:
- There is a significant lack of awareness regarding PGT for SCD among parents.
- Clinic-based education effectively highlights the value of PGT information.
- Healthcare providers should proactively discuss PGT as a reproductive option for families affected by SCD.
Objective:
To evaluate awareness of and attitudes toward preimplantation genetic testing (PGT) for sickle cell disease (SCD) among parents of children with SCD.
Study Design:
Parents of children with SCD were given an educational handbook on PGT before a routine SCD clinic visit. After their clinic visit, parents were asked to complete an anonymous survey.
Results:
Of 83 patents approached, 67 (81%) completed the survey. Only 16 of the 67 parents (24%) were previously aware of PGT for SCD. After our clinic-based education, 65 of the 67 parents (97%) indicated that it was important or very important for parents of children with SCD to know about PGT. Among parents interested in having more children, 29 of 32 (91%) would personally consider using PGT if covered by insurance.
Conclusions:
Parents of children with SCD are generally not aware of PGT. When educated in clinic, parents viewed information on PGT as valuable. Pediatricians and other health care professionals should inform parents of children with SCD about this reproductive option.
