Diagnosis, Dual (Psychiatry) Clinical Trial
Official title:
Dual Diagnosis Inpatients: Telephone Monitoring RCT to Improve Outcomes
This research program will improve the care and treatment outcomes of dually diagnosed veterans who receive inpatient psychiatry care, and decrease their use of VA inpatient mental health services. It will increase the use of substance abuse outpatient care and 12-step groups to benefit recovery, reduce rehospitalizations, and reduce costs for VA.
Background:
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.
Objectives:
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.
Methods:
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.
Status:
As of this time, this project is in the follow-up data collection phase.
