[Data input management in clinical trial].
Data management in the clinical trial is not always processed adequately in Japan. Data management largely depends on the doctor who is in charge of the study. For the effective data processing to the computer, careful attentions should be paid to the proper selection of data-items and quantity, design of data format, coding of data to the format, and the procedure of data input into the computer. These procedures are mainly owed to data managers and computer engineers in the large clinical trials of western countries. Establishing local and central data center and identify of the data manager in our country are urgent for effective implementation of multiinstitutional clinical trial.
