Improving knowledge of rare disorders since 1993: the Australian Paediatric Surveillance Unit

Area of Science:

• Pediatric Epidemiology
• Public Health Surveillance
• Rare Disease Research

Background:

• Established in 1993, the Australian Paediatric Surveillance Unit (APSU) was created to address the lack of national data on rare childhood disorders.
• APSU functions as a prospective, active surveillance system utilizing monthly reports from approximately 1500 pediatricians nationwide.

Purpose of the Study:

• To highlight the 30-year impact and contributions of the Australian Paediatric Surveillance Unit (APSU) to rare disease research and child health.
• To underscore the collaborative nature, productivity, and value of APSU data in informing clinical practice, policy, and national health strategies.

Main Methods:

• Prospective, active surveillance of rare childhood disorders through monthly reporting by a network of pediatricians.
• Data collection includes demographic and clinical information on incident cases, with high return rates (>90%) and data provision (>90%) sustained over 30 years.
• Initiation of 72 studies across rare infections, genetic, psychological, neurological disorders, and injuries, alongside collaborative efforts and expanded research remits.

Main Results:

• APSU has generated over 300 publications and initiated 72 studies on a wide range of rare childhood conditions.
• Sustained high participation rates from pediatricians (>90% return rates, >90% data provision) demonstrate a strong commitment to surveillance.
• APSU data serve as the primary national source for many rare disorders, informing government reporting (e.g., WHO), national strategies, and investigations into disease outbreaks.

Conclusions:

• The Australian Paediatric Surveillance Unit (APSU) is an invaluable, long-standing research resource that significantly contributes to understanding rare childhood disorders.
• APSU data directly inform pediatrician education, clinical practice, health policy, and service development, leading to improved evidence-based care and child health outcomes.
• APSU's success has facilitated international collaboration through the International Network of Paediatric Surveillance Units (INoPSU) and supports the development of similar surveillance systems globally.
