Reducing morbidity among licit substance-using adolescents: A record-linkage assessment of a brief intervention
This randomised trial of adolescents presenting to hospital emergency departments in Perth with problems related to alcohol or other drug use, used the then recently implemented system of linking records in hospitals and medical practices in Western Australia. The aim of this research was to validate the use of hospital record linkage procedures as a method of collecting follow-up data and to use this methodology to assemble outcome data on the study cohort.
