Improving Recognition of Treatable Rare Neuromuscular Disorders in Primary Care: A Pilot Feasibility Study

Area of Science:

• Pediatrics
• Neurology
• Genetics

Background:

• Innovative treatments for neuromuscular disorders (NMDs) exist, but diagnostic delays hinder timely intervention.
• Early identification of NMDs in children is crucial for improving health outcomes.
• Current diagnostic pathways often involve significant delays, impacting treatment efficacy.

Purpose of the Study:

• To assess the feasibility of a novel, three-step sequential screening program for identifying children at high risk for NMDs within the first 30 months of life.
• To evaluate the effectiveness of primary care pediatricians in identifying potential NMD cases through developmental milestone assessments.
• To establish a streamlined referral pathway from primary care to specialized NMD care.

Main Methods:

• The Promoting Early Diagnosis for Neuromuscular Disorders (PEDINE) project implemented a sequential screening process in a population of 300,000.
• Step 1 involved primary care pediatricians assessing motor development milestones during routine visits to detect NMD 'red flags'.
• Step 2 included community neuropsychiatric assessments for screen-positive children, followed by referral to tertiary care (Step 3) if NMD was suspected.

Main Results:

• Over 10,000 primary care visits were analyzed in the first year of the feasibility study.
• Twenty children (0.2%) screened positive for potential NMDs and were referred for further assessment.
• Four of the referred children exhibited elevated creatine kinase (CK) serum levels, indicating potential muscle disorders.

Conclusions:

• Primary care-based screening for NMDs is a feasible approach for early identification of at-risk children.
• The PEDINE project successfully demonstrated the potential for prompt identification of children with potential muscular disorders.
• Implementing such screening programs can significantly reduce diagnostic delays for NMDs in early childhood.
