|Diagnosis, Dual (Psychiatry)||Behavioral: Telephone Monitoring (TM) with Motivational Interviewing Other: Usual care||Phase 2|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Health Services Research
|Official Title:||Dual Diagnosis Inpatients: Telephone Monitoring RCT to Improve Outcomes|
- Readiness to Attend Substance Use Disorder Continuing Care [ Time Frame: 3 months post-intervention ]Readiness to attend substance use disorder continuing care; scale range=0-4, with 0=not ready to do; 4=already doing; higher scores indicate a better outcome.
|Study Start Date:||April 2011|
|Study Completion Date:||June 2015|
|Primary Completion Date:||June 2014 (Final data collection date for primary outcome measure)|
Active Comparator: Usual Care
Psychiatry inpatient usual care
Other: Usual care
All patients in the trial will receive usual care (i.e., the care they would have received in the absence of a study).
Experimental: Telephone Monitoring
Patients in the TM condition will receive an in-person session while in treatment, followed by monitoring over the telephone for three months after discharge. The intervention will incorporate motivational interviewing to monitor patients' substance use, facilitate entry into outpatient treatment, and encourage 12-step self-help group participation.
Behavioral: Telephone Monitoring (TM) with Motivational Interviewing
Patients in the TM condition will receive an in-person session while in the inpatient psychiatry program, followed by monitoring delivered over the telephone for three months after discharge. The TM intervention will have a motivational interviewing component to address patients' motivation to obtain help for and reduce their substance abuse. The purpose of the intervention condition is to monitor patients' substance use, facilitate patients' entry into outpatient substance use disorder (SUD) treatment, and encourage ongoing 12-step selfhelp group participation to support sobriety.
Substance use disorders (SUDs) are highly prevalent among veteran psychiatry inpatients. Dual substance use and psychiatric disorders are related to poor outcomes and rehospitalizations, which are quite costly. However, relatively little is known about how to effectively help dually diagnosed psychiatry inpatients. Telephone Monitoring (TM) is effective among SUD patients at increasing SUD continuing care and self-help utilization and improving SUD outcomes. This study will build on these findings and contribute important new clinical knowledge by determining whether TM is similarly effective when adapted for dually diagnosed veteran psychiatry inpatients. It will evaluate the effectiveness of a manual-guided TM intervention.
Primary hypotheses are that patients in the TM condition, compared to patients in usual care (UC), will attend more SUD continuing care sessions and 12-step group meetings, and have better SUD and psychiatric outcomes. Secondary hypotheses are that TM patients will have fewer and delayed rehospitalizations, and their better outcomes will be mediated by SUD outpatient treatment and 12-step group participation.
This study will take place at two VAs: Palo Alto (VISN 21) and Ann Arbor (VISN 11). Dually diagnosed patients in psychiatry inpatient treatment will be randomly assigned to UC or TM. Patients in the TM condition will receive an in-person session while in treatment, followed by monitoring over the telephone for three months after discharge. The intervention will incorporate motivational interviewing to monitor patients' substance use, facilitate entry into outpatient treatment if a relapse occurs, and encourage 12-step self-help group participation. Patients will be assessed at baseline, end-of-intervention, and six months and one-year post-intervention for primary and secondary outcomes and non-VA health care; VA health care will be assessed with VA databases. GLMM analyses will be conducted to compare the UC and TM groups on course of primary and secondary outcomes over time; Cox regression models will compare groups on time to rehospitalization; and sequential regression analyses will examine whether outcomes associated with TM are mediated by more SUD continuing care and 12-step group participation.
As of this time, this project is in the follow-up data collection phase.
