Clinic-based infant screening for duchenne muscular dystrophy: a feasibility study

Area of Science:

• Pediatric Health
• Genetics
• Public Health Screening

Background:

• Duchenne muscular dystrophy (DMD) is a severe genetic disorder affecting young males.
• Current screening practices primarily focus on newborns, with limited research on broader pediatric screening.
• Assessing parental and provider perspectives is crucial for implementing new screening programs.

Purpose of the Study:

• Evaluate the desirability and feasibility of Duchenne muscular dystrophy (DMD) screening in a pediatric setting.
• Assess the effectiveness of the informed consent process for DMD screening.
• Gauge parental and healthcare provider attitudes towards DMD screening.

Main Methods:

• Conducted voluntary Duchenne muscular dystrophy (DMD) screening for male infants during 12-month well-child visits.
• Utilized post-screening questionnaires for parents and providers to gather feedback on experiences and attitudes.
• Screened 264 male infants in a participating pediatric clinic.

Main Results:

• 78% of parents supported voluntary DMD screening, and 91% of providers favored screening.
• Approximately 75% of parents demonstrated adequate knowledge of DMD screening post-consent.
• The study confirmed the feasibility of conducting DMD screening within a pediatric office environment.

Conclusions:

• Duchenne muscular dystrophy (DMD) screening is a viable option within pediatric offices, particularly within research contexts.
• Parental and provider support suggests potential for optional public health screening for DMD.
• Future implementation could extend beyond newborn screening to routine pediatric care.
