In a clinical trial recruiting process, online advertisements are strategically placed on websites. When a respondent clicks the advertisements, a screening process, optionally a multiple level screening process, is conducted to screen the respondent for participation in a clinical trial program. Contact information and other data points are collected from successfully screened respondents, securely stored in a data storage unit to maintain the confidentiality and readiness of the same for auditing, and transmitted to a clinical trial conducting organization. The effectiveness of the online advertisement is periodically evaluated to maximize recruitment efficiency. |
