Problem and Purpose
• Over the past several decades there has been a
growing recognition that a subset of substance users
suffers from a chronic condition that requires multiple
episodes of care over several years.
• This presentation will focus on
1. Quantifying the patterns that demonstrate that
substance use disorders are a chronic condition
2. Examining the cycle of relapse, treatment,
incarceration and recovery that characterize the
course of this condition and what predicts transition
3. Presenting the results of two experiments designed
to improve the ways in which this condition is
managed across time and multiple episodes of care.

Definition of Chronic SUD
• The American Psychiatric Association (APA, 1994, 2000)
and the World Health Organization (WHO, 1999) use the
term “substance dependence” to indicate a pattern of
chronic problems (e.g., withdrawal, inability to stop,
giving up activities) that are likely to persist.
• They use the term “substance abuse” to identify people not
meeting the dependence criteria but having other moderate
severity symptoms (e.g., hazardous use, legal problems)
suggesting the need for treatment.
• These standards also recognize that the course of substance
use disorders includes periods of relapse, treatment,
incarceration, and remission (i.e., the absence of symptoms
while in the community)

Treatment Participation
• Only 1 in 5 people with dependence or abuse in the U.S. receive
any kind of treatment, and about half of those access it through
publicly-funded substance abuse treatment (Epstein, 2002)
• People presenting to publicly funded treatment with dependence
(vs. others with abuse, intoxication, primarily other psychiatric
diagnoses) are more likely to have been
– in treatment before one or more times (57% vs. 39%, OR=1.46,
p<.05),
– in treatment 3 or more times (16% vs. 9%, OR=1.79, p<.05),
– assigned to intensive outpatient (15% vs. 6%, OR=2.52, p<.05)
– assigned to residential treatment (16% vs. 5%, OR=3.17, p<.05)
(OAS, 2002 on line data at
http://webapp.icpsr.umich.edu/cocoon/ICPSR-SERIES/00056.xml)
• People with 3 or more diagnoses were significantly more likely
than those with just 1 diagnosis to enter treatment (34% vs. 7%)
(Kessler, et al., 1996).

Pathways to Recovery Study (Scott & Dennis)
Recruitment:
Sample:
1995 to 1997
1,326 participants from sequential admissions to
a stratified sample of 22 treatment units in 12
facilities, administered by 10 agencies on
Chicago's west side.
Substance:
Cocaine (33%), heroin (31%), alcohol (27%),
marijuana (7%).
Levels of Care: Adult OP, IOP, MTP, HH, STR, LTR
Instrument:
Augmented version of the Addiction Severity
Index (A-ASI)
Follow-up:
Of those alive and due, follow-up interviews were
completed with 94 to 98% in annual interviews out
to 8 years (going to 10 years); over 80% completed
within +/- 1 week of target date.
Funding:
CSAT grant # T100664, contract # 270-97-7011

Survival Analysis
• Time frames related to age of use, treatment, and death
were measured across all sources and waves of
information (taking the earliest first use, treatment
episode, and 12 month period of abstinence or death).
• Age at last use was defined as the age when a person
first completed a period of 12 month abstinence or had
died (35 or 2.6% of the people died in 3 years).
• Durations were estimated with Cox Proportional
Hazards Regression
– censoring people who were in treatment or still using,
– censoring years past which we had less than 100 people to
make the estimate, and
– creating a 30 year window of observation on the trajectory of
substance use disorders starting at the time of first use

Post Script on the Pathways Study
• There is clearly a subset of people for whom
substance use disorders are a chronic condition that
last for many years
• Rather than a single transition, most people cycle
through abstinence, relapse, incarceration and
treatment 3 to 4 times before reaching a sustained
recovery.
• It is possible to predict the likelihood risk of when
people will transition
• Treatment predicts who transitions from use to
recovery and self help group participation predicts
who stays in recovery.

Need For Treatment Re-Intervention
•
Eligibility: Not already in treatment or incarcerated and
living in the community
•
Need: Yes to at least one of the following…
(a) During the past 90 days, have you used alcohol,
marijuana, cocaine, or other drugs on 13 or more days?
(b) During the past 90 days, have you gotten drunk or been
high for most of 1 or more days?
(c) During the past 90 days, has your alcohol or drug use
caused you not to meet your responsibilities at
work/school/home on 1 or more days?
(d) During the past week, had withdrawal symptoms when you
tried to stop, cut down, or control your use?
(e) Do you feel that you need to return to treatment?
(f) During the past month, has your substance use caused you
any problems?
Note alpha > .90
25
Recovery Management Checkups (RMC)
in both ERI 1 & 2 included:
• Quarterly Screening to determining “Eligibility”
and “Need”
• Linkage meeting/motivational interviewing to:
– provide personalized feedback to participants
about their substance use and related problems,
– help the participant recognize the problem and
consider returning to treatment,
– address existing barriers to treatment, and
– schedule an assessment.
• Linkage assistance
– reminder calls and rescheduling
– Transportation and being escorted as needed
26
Modifications to RMC for ERI -2 included:
• Switch to from off- to on-site urine monitoring with
immediate feedback on results (before detailed
questions) to allow to probing and improve
identification
• Transportation assistance for everyone to improve the
show rates for assessment and treatment
• Improved Quality Assurance/Adherence
• Engagement assistance to improve the rates of staying
at least 14 days
– Daily contact (mostly face to face)
– Acting as an ombudsman
– Agreement from provider not to administratively
discharge from treatment without contacting us first

Other Variables That Lost
Significance in Multivariate Model
• Problem Recognition, External Pressure, Internal
Motivation, Treatment Resistance
• Current Withdrawal, Number of Diagnosis,
Emotional Problems, Illegal Activity,
Homelessness
• Coming from a controlled environment
• Involvement with the Criminal Justice System,
Mental Health, Health, or Training/School
Systems
• Lifetime number of prior treatment, arrests
• Gender, Race, Age, Employment
36
Post Script on ERI experiments
• Again, severity was inversely related to returning to
treatment on your own and treatment was the key
predictor of transitioning to recovery
• The ERI experiments demonstrate that the cycle of
relapse, treatment re-entry and recovery can be
shortened through more proactive intervention
• Working to ensure identification, showing to
treatment, and engagement for at least 14 days upon
readmission helped to improve outcomes
37
These studies provide converging
evidence demonstrating that
• substance use disorders are often chronic in the sense
that they last for years and the risk of relapse is high
• the majority of people accessing publicly funded
substance abuse treatment have been in treatment
before, are likely to return, have a variety of cooccurring problems and may need several additional
episodes of care before they reach a point of stable
recovery.
• Yet over half do make it to recovery and the odds of
getting to and staying in recovery can be improved
with proactive management.
38
We need to..
• Educate policy makers, staff and clients to have more
realistic expectations
• Redefine the continuum of care to include
monitoring and other proactive interventions between
primary episodes of care.
• Shift our focus from intake matching to on-going
monitoring, matching over time, and strategies that
take the cycle into account
• Identify other venues (e.g., jails, emergency rooms)
where recovery management can be initiated
• Evaluate the costs and determine generalizability to
other populations through replication
• Explore changes in funding, licensure and
