Clinical Trial Summary

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 clinical data and imaging core for multi-disciplinary pediatric experts who perform international collaborative research 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.

Description:

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 dataset 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), hemorrhagic stroke or those at high risk (e.g. arteriopathies like moyamoya).

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Pediatric Stroke Outcome Measure at 3 months.	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.	3-12 months post-stroke
Primary	Recovery and Recurrence Questionnaire	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 was then assessed, and validated. The RRQ captures 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.	3-12 months post-stroke
Primary	King's Outcome Scale for Childhood Head Injury (KOSCHI)	The KOSCHI is a standardized outcome measure and was developed as a pediatric adaptation of the original adult Glasgow Outcome Scale. It is a widely used outcome measure post neurological injury in children and have been used in previous pediatric stroke research. The KOSCHI can be completed through chart review of clinical or progress notes.	3-12 months post-stroke
Primary	modified Rankin Scale (mRS)	The modified Rankin Scale is a standardized outcome measure that captures the degree of disability in patients who have had a stroke. It is widely used in previous pediatric stroke research to assess global neurological impairment following stroke in children. It is a single-item scale and can be completed through chart review of clinical or progress notes.	3-12 months post-stroke
Secondary	Investigator-Initiated Research Studies	Participating in the IPSS gives investigators permission to conduct multi-site research studies, in accordance with the Publications Committee policy.
