With the implementation of the Alcohol and Drug Abuse and Mental Health Services Block Grant Program in October 1981, CODAP was no longer a required reporting process. In view of the utility of client treatment data for epidemiologic study, however, NIDA embarked on an effort to obtain such data on a voluntary basis from States which continued to collect them. The initial approach involved: (1) continued operation of existing CODAP software; (2) continued processing as usual of State data submitted in CODAP format; and (3) preprocessing nonconforming data into a CODAP-compatible form. At the time, this represented both a reasonable and feasible approach for several reasons: (1) more than half of the States continued to operate CODAP on their own; (2) it required few NIDA resources, primarily a programmer to operate the available CODAP software; and (3) it placed few demands on participating States.
As more and more States developed their own systems, independent of CODAP, the approach designed to force all data through the CODAP system software became less and less viable. While data from two State systems were successfully converted to CODAP format for processing by the CODAP software, it became apparent that such conversions were not feasible for all State systems. At the same time, the need and demand for a national client data base escalated.
