Survey of Key Informants' Patients

The Survey of Key Informants’ Patients Program collects data on specific prescription opioids and illicit drugs endorsed by patients entering treatment for substance dependence or addiction.


The Survey of Key Informants’ Patients Program gathers data from a key informant network of 154 treatment programs yielding approximately 3,000 survey respondents annually from 47 states. The patients who seek treatment at primarily private substance abuse treatment programs are recruited by key informants to voluntarily complete an anonymous questionnaire with items about primary drug of abuse, sources of drug acquisition, use in the month prior to treatment, and routes of abuse.
