A computer-based method for centralized collection of geographically distributed clinical trial data from at least one user at a remote site computer (2) has a World Wide Web browser (3). It comprises connecting, by the remote site computer (2) to the Internet, using the World Wide Web, and loading, on a when needed basis, a program of a browser-processable programming language containing a questionnaire to be completed by the user; processing, by the user's browser (3), the browser-processable program, thereby enabling the user to complete the questionnaire, checking the data input by the user for validity, providing the user an opportunity to correct any invalid data found during the checking, transmitting the data to a centralized computer over the Internet using the World Wide Web; receiving and validating the data from the remote site computer at the centralized computer, including comparing the data to data already stored at the centralized computer to determine if it is valid or invalid; if the data from the remote site computer is determined to be invalid, then performing the following until all data is determined to be valid; signaling with the centralized computer to the remote site computer to provide the user an opportunity to correct invalid data; transmitting corrected data from the remote site computer to the centralized computer; and receiving and validating the corrected data from the remote site computer (2) at the centralized computer, including comparing the corrected data to data already stored at the centralized computer to determine if the data is valid or invalid; when all data has been determined to be valid, then entering and storing the valid data in a central database at the centralized computer. <IMAGE>
