Background Collection of individual patient data on Case Report Forms CRFs in clinical research has traditionally been done by investigators in their offices summarizing medical charts on paper forms pCRFs , a tedious method that could result in data errors and wrong conclusions [ 1 , 2 ]. Methods The primary endpoint was the satisfaction of stakeholders in a clinical study: investigators, clinical research associates CRAs and data managers DMs. Material Clinical studies: inclusion criteria We retrospectively selected biomedical research studies monitored by 6 research units involved in eCRF testing, completed between and or for eCRFs and sponsored by the Paris regional hospital consortium AP-HP.
Stakeholders We investigated the satisfaction and preference of three stakeholder groups: investigators, clinical research associates CRAs and data managers DMs for both types of CRF. Methods Clinical studies We collected protocols, budgets and expense statements, CRFs, monitoring reports and other relevant technical documents. Cost estimation The cost of a study was estimated from: labor costs, i. Statistical analysis Clinical studies The unit of analysis was the study. Open in a separate window. Clinical studies Time from the opening of the first center to database lock tended to be shorter with eCRFs SE: standard error.

Table 6 Main themes discussed by stakeholders in open-ended questions. Answers from investigators, clinical research associates and data managers. Discussion In this first description of the use of eCRFs and pCRFs across 27 clinical studies, we found that most stakeholders were satisfied with eCRFs and that the use of eCRFs was associated with shorter study duration and lower cost per patient.
