Clinical data acquisitionAcquisition or collection of clinical trial data can be achieved through various methods that may include, but are not limited to, any of the following: paper or electronic medical records, paper forms completed at a site, interactive voice response systems, local electronic data capture systems, or central web based systems. There is arguably no more important document than the instrument that is used to acquire the data from the clinical trial with the exception of the protocol, which specifies the conduct of that clinical trial.
Electronic data captureAn electronic data capture (EDC) system is a computerized system designed for the collection of clinical data in electronic format for use mainly in human clinical trials. EDC replaces the traditional paper-based data collection methodology to streamline data collection and expedite the time to market for drugs and medical devices. EDC solutions are widely adopted by pharmaceutical companies and contract research organizations (CRO).
Case report formA case report form (or CRF) is a paper or electronic questionnaire specifically used in clinical trial research. The case report form is the tool used by the sponsor of the clinical trial to collect data from each participating patient. All data on each patient participating in a clinical trial are held and/or documented in the CRF, including adverse events. The sponsor of the clinical trial develops the CRF to collect the specific data they need in order to test their hypotheses or answer their research questions.
Essai cliniqueUn essai clinique, ou étude clinique, ou encore essai thérapeutique, est une étude scientifique réalisée en thérapeutique médicale humaine pour évaluer l'efficacité et la tolérance d'une méthode diagnostique ou d'un traitement. L'objectif d'un essai n'est pas d'apporter un bénéfice thérapeutique au volontaire. Le Comité international des rédacteurs de revue médicales en donne la définition suivante : . Ces études sont souvent effectuées après des études expérimentales non-cliniques (sur des modèles animaux ou cellulaires) pour confirmer leur pertinence et leur sécurité.
