The International Pediatric Stroke Study (IPSS) was established in 2003 as a multi-center, multi-national clinical research registry. Over the years, it has grown to become a highly successful study vehicle for pediatric stroke research across over 100 institutions worldwide. Today, The IPSS continues to serve as the global data and imaging core for multi-disciplinary pediatric experts who perform international collaborative research in an effort to better understand, prevent, and improve outcomes in pediatric stroke. The robust dataset and cohesive network enable high caliber and ground-breaking research in the field.
Participating sites enroll neonates or children who have had an ischemic stroke or are at high risk of having a stroke into the registry. Participants have their medical and research records reviewed for information about their stroke and abstracted into a secure electronic database called REDCap. The IPSS also provides an attractive imaging platform (through the Stroke Imaging Lab for Children, SILC, housed at SickKids) for sites to share clinically acquired brain images that will complement the clinical dataset. The clinical and imaging datasets will improve our understanding of the processes underlying plasticity and recovery in childhood stroke.
All information captured in the study is de-identified.
This study does not require any interventions or additional visits for research. Two outcome measures are typically administered during a follow-up clinic visit: the Paediatric Stroke Outcome Measure (PSOM) and the Recovery and Recurrence Questionnaire (RRQ). The PSOM is used during clinic visits by the study PI or co-investigator; the RRQ is a parental questionnaire that can be completed during clinic visits or by telephone interview for those parents who cannot attend the follow up appointment. Both measures assess neurological function in the following 5 domains: sensory, motor, language, cognition and behavior.
Participating investigators will retain ownership of their own (single-site) data. However, by entering data into the IPSS, co-investigators give implicit permission for the IPSS to analyze the collective dataset. These contributing investigators are recognized through authorship.
The activities of the network are creating the opportunity for manuscript writing, grant development and collaboration on clinical challenges in pediatric stroke.

OBJECTIVES: This is the first multi-center, multi-national study of children with stroke. It seeks to build a network of investigators and high-quality disease data to enable population-based studies, natural history studies, and clinical trials to improve the care of children with stroke.
STUDY POPULATION: Infants and children with ischemic stroke (arterial ischemic stroke and cerebral sinovenous thrombosis), or those at high risk (e.g. arteriopathies).
DESIGN: This study includes a data collection component and collaborative process. Our network of over 150 investigators prospectively collect data on neonates or children with a diagnosis of stroke made after January 2003. Data on stroke diagnosis, etiology, treatment and outcomes are collected and entered into a secure web system, REDCap. Neuro-imaging data from the index event and a series of follow-up time points are captured and stored in the SILC-IPSS data repository.
OUTCOME MEASURES: This study will quantify outcome event rates (initial stroke characteristics, recurrent stroke, mortality, neurologic deficits), which can be used in designing future intervention studies and determining sample sizes. Analysis will be primarily descriptive. Participating investigators submit investigator-initiated research proposals or grants with a specific focus, leveraging the clinical and imaging dataset.

- Change from Pediatric Stroke Outcome Measure at 3 months. [ Time Frame: 3 & 12 months post-stroke ]The Pediatric Stroke Outcome Measure (PSOM) was developed out of a need for an objective, standardized outcome measures for children with acute, unilateral focal CNS such as cerebral infarction. The goal was to develop an assessment measure that defines clinically and functionally relevant outcome in pediatric stroke. This measure was designed for and tested in children with arterial ischemic stroke or cerebral sinovenous thrombosis.
- Recovery and Recurrence Questionnaire [ Time Frame: 3 & 12 months post-stroke ]The Recurrence and Recovery Questionnaire (RRQ) was developed by converting the Pediatric Stroke Outcome Measure (PSOM) into a questionnaire for patient/parent telephone interview. The agreement and consistency of the PSOM and RRQ is then assessed, and identified conditions that contributed to differences between the 2 measures. The RRQ has been validated to capture the same 5 sub-domains as the PSOM in the event a patient cannot return to clinic for a follow-up visit and can be used as a measure of recovery post-stroke.
- Investigator-Initiated Research Studies [ Time Frame: As proposed ]Participating in the IPSS gives investigators permission to conduct multi-site research studies, in accordance with the Publications Committee policy. Manuscripts published to date can be accessed through IPSS Central (email@example.com).
