Exclusion Criteria:
US Sites: Exclusion Criteria
Patients
- Pregnancy. Women who report being pregnant at the time of randomization will be excluded from participation. This latter exclusion criterion is based on the following reasons: (a) The interaction of drug use (in any amount) and fetal-maternal health is physiologically complex and beyond the scope of this proposed intervention. (b) Drug users who are pregnant are considered high-risk pregnancies and will likely be lost to follow-up during the study as they will be promptly referred by their primary care clinician to an obstetrician per usual clinic protocol. However, enrolled patients who become pregnant after the intervention will not be withdrawn. Their eventual exits from the study will be counted as drop-outs and will be included as "no change" in our "intent to treat" analysis. Finally, (c) a tailored brief intervention protocol for pregnant women may require more than simple clinician advice and a 2-session phone health education program. Such an intervention would be more effective if designed around the activities of prenatal care. Previous RCTs of problem alcohol use targeting healthy adults have excluded patients who are pregnant.8,9
- Homeless status. The clinics we have chosen have large numbers of homeless patients. Since this is a study on the general poverty population, we are asking homeless status in order to avoid over-sampling homeless patients. We will set a quota on number of homeless patients we can enroll without over-sampling these patients. If we reach this quota, we will apply homeless status as an exclusion criteria for subsequent subjects.
- Repeaters. Patients who have been screened or enrolled before will be asked a set of repeater questions. This includes a question on whether they have ever been involved in our UCLA study at the clinic before. We will also ask them a set of questions that combines aspects about the potential subject (mother's first name, father's first name, month and day of birth) that will screen them out if they screen again in the future.
- ASSIST Score: Drug Dependence. The RA will receive a message that the subject scored 27+ on all illicit drugs on the WHO ASSIST (i.e. indication of possible substance dependence/addiction). The RA will inform the patient that they are at risk for certain health behaviors and ask the patient if they want to disclose this information to their doctor. If they agree to disclose information to their doctor then we will fill out a letter informing the doctor of patient's dependence on specific drugs. We will also provide the patient with a list of local substance abuse treatment referrals. Please see Appendix A for copies of these referrals (Appendix A. Los Angeles County Substance Abuse Treatment Facilities).
- From Date of Screening Subject Enrolled in a Drug Treatment Facility. Subjects enrolled in a treatment program are excluded from the study. These subjects show commitment to the treatment program. Moreover, these program would serve as a competing intervention to ours, biasing the potential effect of our intervention.

Kísérleti: Intervention
The Quit Using Drugs Intervention Trial (QUIT) experimental arm includes: screening, very brief clinician advice, and telephone drug-use health education to reduce 'at risk' drug use and thus interrupt progression from casual or episodic abuse to dependence.
|
The goal of the Quit Using Drugs Intervention Trial (QUIT) is to conduct a small RCT of a primary care clinic-based very brief intervention protocol for reducing the use of illegal drugs and the occurrences of drug-related harm in low-income, racially-diverse patient populations at two 'safety-net' clinics in Los Angeles.
The design will emphasize screening, very brief clinician advice, and telephone drug-use health education to reduce 'at risk' drug use and thus interrupt progression from casual or episodic abuse to dependence.
