The importance of continued analysis of information routinely obtained in health services so that necessary readjustments at the right time may be made by allowing such information to be used in scientifical planning, thus improving efficiency, is here discussed. An antirabic vaccination service in a Health Center was chosen for evaluation. The population studied was that which turned up at the service at the time of the present study (June 1969 to April 1973). The influence of urbanization and the distance from the main town on the flow of people towards the service were analysed as well as the schedules employed for antirabic vaccination. As much as possible the authors compared the data obtained with those of other services and concluded that the differences discovered were not significant.
