Primaire uitkomstmaten
The primary outcome measure (i.e. predicted outcome) is ‘restrictions in participation’ according to the restrictions subscale of the USER-P, dichotomized as ‘2 or more restrictions’ vs. ‘0 or 1 restriction’ at 12 months.
Achtergrond van het onderzoek
Rationale: In survivors after cardiac arrest, the reported incidence of cognitive and emotional disturbances is high. These may lead to functional impairments and restrictions in participation. Early prediction of cognitive disturbances, levels of activity, or restrictions in participation would support rehabilitation, but are unavailable.
Objective: Primary objective is to create a prediction model based on clinical factors derived from early screening of motor, cognitive, and emotional functioning to predict restrictions in participation at one year after cardiac arrest. Secondary objectives include prediction models for cognitive disturbances and levels of activity, and to study additional predictive values of EEG and MRI measurements.
Study design: This will be a prospective, longitudinal, multicenter cohort study. Patients will be included, and clinical, MRI, and EEG measures of brain damage will be collected 4 +/- 3 weeks after cardiac arrest, during admission on cardiac care units or cardiology departments. Follow-up will be one year.
Study population: 200 adult patients after cardiac arrest and cardiopulmonary resuscitation, that have survived the acute phase and awakened from coma.
Main study parameters/endpoints: The primary outcome measure (i.e. predicted outcome) is ‘restrictions in participation’ according to the restrictions subscale of the USER-P, dichotomized as ‘2 or more restrictions’ vs. ‘0 or 1 restriction’ at 12 months. Secondary outcome measures (i.e. predicted outcomes) include cognitive disturbances, levels of activity, and sleep disturbances at 12 months. Determinants (i.e. independent variables) will be collected at 4 +/- 3 weeks after cardiac arrest and include demographic factors, clinical factors, MRI, and EEG measurements.
Doel van het onderzoek
Long-term cognitive, emotional and functional disturbances after cardiac arrest can be predicted based on early demographic, clinical, EEG, and MRI measures.
