Electronic Clinical Outcome Assessment (eCOA) Services

eCOA for Clinical Trials

Electronic Clinical Outcome Assessment (eCOA) systems are a technology that enables the capture of clinical trial data directly from patients, clinicians, and observers. This umbrella term covers any digital means of documenting patients’ condition, symptoms, and treatment effects. Electronic Patient-Reported Outcomes (ePRO) are a subset of eCOA, and represent the data collected directly from patients without third-party amendment or interpretation. ePROs are often conducted remotely on devices such as tablets, computers, and smartphones, whereas eCOA may also be captured in-person and encompasses clinician assessments and medical devices.

In many clinical trials, eCOAs are a critical component because they provide valuable insights into a patient’s disease progression and overall well-being. Decades ago, patient reported outcomes (PROs) were collected using paper-based methods, which were liable to loss/destruction, transcription errors, and data inconsistency. Today’s eCOA innovations allow patients to complete questionnaires electronically, either on their own devices or through a dedicated study portal. Patients can complete eCOA assessments from their own homes, and the data can be transmitted securely to the clinical trial database.
