Building a national hospital registry of children and teens with cerebral palsy in Italy

This project aims to create a shared digital platform across clinical centers throughout Italy (three coordinative centers for northern, central, and southern Italy). This platform will allow systematic, standardized, retrospective, and prospective data collection, including clinical, instrumental, and genetic data (where available) for patients with CP. The study intends to complement ongoing national projects, such as the "Italian Network for Early Detection and Intervention in Developmental Disabilities (INEED)" and the "Italian Network for Cerebral Palsy (Ita-Net-CP)."

STUDY OBJECTIVES

This study aims to analyze epidemiological data, specifically:

* Evaluating the prevalence of various clinical types of CP * Assessing the distribution of functional impairment severity and associated comorbidities.

STUDY DESIGN This is a non-profit, multicenter, observational study involving a cohort of CP patients, promoted within the Mariani Foundation Network. The study involves both retrospective and prospective data collection. It will enroll both patients already under care for follow-up and newly diagnosed patients.

A sample of at least 300 children and/or adolescents with CP of various etiologies, with 100 participants per clinical center, is targeted. Enrollment will be voluntary, either by invitation from the referring physician, who will explain the importance of the registry, or through project dissemination, allowing parents to request their children's inclusion. Basic registry items can be filled out by parents and, with permission, the primary physician for clinical fields. Parents can opt to be included in the registry to receive information on national clinical studies, approved by ethics committees.

Collected essential data includes:

* Identification and contact information for patient pseudonymization * Socioeconomic status * CP classification according to the European Surveillance Group * Anamnesis regarding disorder etiology * Neuroradiological classification based on SCPE (MRICS) * Functional impairment level of each child * Significant comorbidities

STUDY POPULATION At least 300 pediatric CP patients aged 4-18 years are expected to be recruited. Exclusion criteria only include lack of informed consent.

DRUG, MEDICAL DEVICE, NUTRACEUTICAL, BIOLOGICAL SAMPLES, OTHER ELEMENTS This observational study involves systematic, standardized retrospective and prospective data collection of clinical, instrumental, and genetic data (if available). No medical devices, pharmaceuticals, or nutraceuticals will be used. No human biological samples will be collected.

STUDY TIMELINE Study duration per patient: aligned with routine clinical visits. No additional evaluations are foreseen.

Recruitment duration: 12 months Overall study duration: 36 months

SAMPLE SIZE AND DATA ANALYSIS The study aims to recruit at least 300 pediatric CP patients. A control group is not planned.
