Predicting Persistent Postconcussive Problems in Pediatrics (5P)

Conditions: PCS
Concussions

Registration Number: NCT01873287

Lead Sponsor: Children's Hospital of Eastern Ontario

Brief Summary: Concussion, a mild traumatic injury common in children and adolescents, is a complex pathophysiological process affecting the brain. The lay press is inundated with reports of tragic consequences of concussion, and children are not immune.

Persistent postconcussive symptoms (PCS) is defined as the persistence of somatic, cognitive, physical, psychological or behavioural changes lasting more than one month following injury. PCS significantly impacts children and their family's quality of life through school absenteeism, depressed mood and loss of activities.

Validated, easy-to-use prognosticators do not exist for clinicians to identify children at highest risk for PCS. As a result,physicians cannot accurately inform children and parents whether they should expect longer symptoms, nor initiate pharmacotherapy or other management to reduce the occurrence or severity of PCS.

The investigators objective is to derive and validate a clinical prediction rule for the development of PCS in children and adolescents presenting to the emergency department (ED) following acute head injury. The investigators have three aims: (1) determine PCS incidence at one-month follow-up in children aged 5-17 who sustain a concussion; (2) derive a rule to predict PCS from variables present in the history and physical examination; and, (3) assess the accuracy, reliability and acceptability of the prediction rule in a subsequent cohort. Using a prospective, multicentre study at nine large Canadian pediatric EDs, the investigators will recruit the largest prospective epidemiological cohort of children with concussions in the literature.

This work will provide rigorous evidence to determine PCS incidence in children and its impact on quality of life. The results will enable clinicians to identify children at highest risk for PCS, optimize treatment and provide families with realistic anticipatory guidance. This study will also establish a strong and vital evidence base to advance concussion research.

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 3063

Inclusion Criteria

Subjects presenting to one of the study hospital EDs after sustaining a head injury will be eligible if they:

are aged 5 to 17 years;
have a concussion, defined by Zurich consensus statement;22
suffered the initial injury in the previous 48 hours;
are proficient in English or French.

Exclusion Criteria

Patients will be excluded if they present with traumatic head injuries with any of the following:

GCS ≤13; any abnormality on standard neuroimaging studies, including any positive head CT findings (Note: neuroimaging is not required, but may be performed by the clinician if thought to be clinically indicated);
neurosurgical operative intervention, intubation or PICU care required;
multi-system injuries with treatment requiring admission to hospital, operating room or procedural sedation in the ED (Note: admission to hospital for observation or management of ongoing concussion symptoms is not an exclusion criteria);
severe chronic neurological developmental delay resulting in communication difficulties;
intoxication at the time of ED presentation as per clinician judgment;
no clear history of trauma as primary event (e.g., seizure, syncope or migraine as primary event);
previously enrolled in this same study.

Study & Design

Study Type: OBSERVATIONAL

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Count of Children Who Have Persistent Post-concussive Symptoms (PCS) at One-month Follow-up.	1 month	The primary outcome is the number of of children aged 5 - 17 years who have PCS at one-month follow-up. A PCS case is defined as an increase from pre-concussion baseline of three or more symptoms on the validated PCSI at one-month (consistent with the ICD-10 definition of PCS).

Secondary Outcome Measures

Name	Time	Method
Neuropsychological Evaluation	1 month and 3 month	A separate battery of neuropsychological assessment measures will be administered to those children who choose to participate in this arm of the study. This battery includes measures of intelligence, language, visual-spatial/motor functions, attention, memory/working memory, executive functioning, academic achievement, as well as behavioural/socioemotional functioning.
Pediatric Quality of Life Inventory (PedsQL) Total Score at 4-weeks Post-injury	1 month	The PedsQL™ is a reliable and valid measure of health-related quality of life in healthy children and adolescents and those with acute and/or chronic health conditions. Parent versions exist for children aged 2 to 18 years (in 4 age groups) and child versions for those aged 5 and over. The inventory covers four domains: physical, emotional, social and school. Items are calculated and transformed into an overall score with a range of 0 to 100 points, with more points indicating better quality of life. This secondary outcome measure will be used to determine the impact of PCS on quality of life on patients and families.
