Medicaid and Community Reentry• Medicaid is the single largest payer of mental health
services for persons w SMI in the US today– Council of State Government suggests Medicaid is critical to
successful community reentry – Without sustaining health & welfare benefits justice-
involved persons with mental illness will be unable to “break the cycle of recidivism” (Bazelon Center)
• Federal regulations require suspension or termination of Medicaid benefits after 30 days of incarceration or hospitalization
• A number of states have introduced policies to expedite the restoration of Medicaid benefits prior to release from prison and other institutions 5
What’s the Evidence Base for Expedited Medicaid?
• Wenzlow et al. (2011) small study (N= 77) of expedited Medicaid in 3 Oklahoma prisons– Increased Medicaid enrollment on day of release by 15 percentage
points vs. controls (p=.012)– Increased Medicaid mental health service use by 16 percentage
points (p=.009) vs. controls at 90 days post release
• Morrissey, Cuddeback et al. (2006, 2007) showed that persons w SMI in jail with Medicaid at release had:– Quicker service access & more community service use (p<.001)– Fewer re-arrests, more days in community (p<.01)
• To date, no comparative study of prison re-entry nationally or in different states, no studies with large sample sizes
6
Current Study
• Response to NIMH solicitation in 2008 for use of administrative data to address state-level behavioral health policies
• NIMH required comparison of at least two states
• Assembled a research team from UNC, CT-DMHAS, and Duke that had prior experiences using administrative data to address state policy issues in Washington & Connecticut
7
Expedited Medicaid• Policy start date
– Connecticut: April 2005– Washington: January 2006• Benefits affected by restoration
– Federal Medicaid via SSI/SSDI eligibility » (i.e., Aged, Blind, Disabled)
– State Medicaid, a less generous benefit often used as an initial or transitional status pending Federal Medicaid restoration
» SAGA in Connecticut» GAU in Washington
8
Policy ImplementationConnecticut in 2005
• DOC only• Discharge Planners (6) working
for Correctional Managed Health Care & based in correctional facilities complete paperwork to apply for Medicaid prior to release & fax to state Medicaid agency
• Entitlement specialists (2) based at state Medicaid agency process applications
• Daily e-feed of population list results in benefits being “switched on”
Washington in 2006
• DOC, jails, state hospitals• Two step process
① Referral: DOC staff identified inmates and prepared applications prior to release
② Approval: Following release, inmate had to appear at local Community Service Office to activate application
• Legislature funded and distributed 14 FTE Community Service Officers statewide to prioritize expedited cases
9
Other Differences b/w StatesConnecticut
• Unitary corrections system: State DOC operates prisons and jails
• Much of Medicaid was fee-for-service in the study period
• State Administered General Assistance (SAGA) covered services at a similar rate
• Virtually no one is denied benefits
• Even prisoners not expedited had 2-4 weeks of Rx at the time of discharge
Washington
• Dual corrections system: State DOC operates prisons and County Sheriffs operate jails
• Medicaid managed care with HMO for medical care and carve-outs for behavioral health care
• Federal Medicaid required for access to specialty mental health services
• State Medicaid (GAU) covers meds from primary care MDs
10
Research Design• Case-control study with data available 3-yrs. pre
and 3-yrs.post start of expedited Medicaid policy• Administrative data on inmates with SMI, service
contacts for mental health (inpatient & outpatient), substance use, arrests & incarcerations
• Propensity score analysis used to construct comparison group of inmates with SMI who were not expedited and released during same time period
11
Core Analysis for Inmates w SMI Released from CT & WA Prisons
* Comparison groups matched on propensity scores created from demographics, clinical diagnoses, and behavioral health/criminal justice

Methods for CT Data • Started with DOC discharges w/ 1 year FU• Experimental group defined by DSS• Propensity Scoring
– 1,511 Pre-Release Entitlement (PRE) = E– 1,511 Propensity-matched cases (Non-PRE) = C
• Survival Analysis (Cox Regression)– Time to event (enrollment, OP Tx, IP, arrest, etc)
• Poisson Models for count data
14
Poisson Models• Used in a “conditional” situation: e.g., rate of use of EDs & # visits
– First part is about the likelihood of the situation happening– Second part is the count of the event
• Poisson models involve different assumptions– Poisson regression:
• assumes equally dispersion (the conditional variance equals the conditional mean)
– Negative binomial regression (NB): • allows for over-dispersion
– Zero inflated Poisson model (ZIP): • allows for excess zeros
– Zero inflated Poisson negative binomial regression (ZINB): • allows for over-dispersion and excess zeros
• Need to use the model best-suited to the data15

Summary of CT Findings• In Connecticut, the Pre-Release Enrollment
Program resulted in:– Quicker access to Medicaid– Quicker use & more use of Outpatient services– Reduced use of Inpatient Care– More community days– NS difference in # of visits to EDs/crisis overall– BUT people in PRE were more likely to use EDs– No difference in CJ outcomes

Expedited Medicaid Restoration in Washington State
Gary Cuddeback and Jennifer JolleyUniversity of North Carolina
6th Annual Academic and Health Policy Conference on Correctional Health
Chicago – March 22, 2013
Research Question & Methods• What is the impact of an expedited Medicaid
restoration program for SMI persons released from prison in Washington State?
• Quasi-experimental design w/PSM– Individuals with SMI released from prison in 2006 or
2007 • Approved for expedited Medicaid restoration vs. those
who were referred but not approved or eligible but not referred
– 12-month follow-up after index release in 2006 or 2007
28
Definitions and Data• Severe mental illness defined as having a
diagnosis of schizophrenia or other psychotic disorders and/or bipolar disorder (with some exceptions)– Dx came from community mental health or DOC
• Linked administrative data available from 2003 to 2010 from Washington State CODB– Demographics, diagnoses, Medicaid (program type),
inpatient and outpatient mental health service use, substance use service use, homelessness, employment, arrests, jail (some), violator facilities, prisons
– Linked at person-level to create longitudinal file29
Data Analysis • Regression and survival models with PSM weights and
robust standard errors• HB1290 approval = independent variable• Dependent variables …
– Logistic regression• Probability of Medicaid• Probability of outpatient service• Probability of arrest
– OLS and survival models • Time to Medicaid• Time to first service• Time to arrest
• PSM balanced groups on all observables (more later)

Key Findings• Expedited benefit restoration associated with
– Greater and quicker Medicaid uptake – Greater and quicker access to outpatient mental health
services• Restored benefits not associated with lower probability
of criminal justice events – Some improvement in time in community until prison
• Expedited restoration is working as a health insurance program but few spill-overs for corrections
• But Medicaid alone is not enough as evidenced by role of substance use, homelessness and unemployment in arrest & re-incarceration!

Expedited Medicaid Restoration in Washington State: Cost-
Effectiveness
Marisa Domino and Jennifer JolleyUniversity of North Carolina
6th Annual Academic and Health Policy Conference on Correctional Health
Chicago – March 22, 2013
Cost Analysis
• We examined the cost of expedited Medicaid using a government payer perspective– Costs related to medical and mental health services
use and criminal justice costs were included– Short-run (12 month) time period examined
• We also analyzed days in the community as a measure of effectiveness, for a cost-effectiveness calculation– Days not incarcerated nor in inpatient settings
38
Cost Methods
• Costs of medical and mental health services used actual payments by Medicaid, state, and regional payers for services delivered
• State hospital days costed using per diems• Services include:
– Outpatient medical and mental health services– Inpatient services, including state hospitals and
local inpatient hospitals– Emergency room, crisis treatment, and medications
39
Cost Methods, continued
• Criminal justice costs used Washington State Institute for Public Policy (WSIPP) calculated costs, including costs of:– Arrests– Jail– Prison– Parole
40
Analysis Methods
• Because of concerns over selection bias in that those receiving expedited Medicaid may differ from those not receiving expedited Medicaid, we used propensity score weighting to obtain better balance on baseline risk factors
• Baseline risk factors include: time in prison and jail, year of release, race/ethnicity, age, gender, prior history of mental health service use, homeless prior to index incarceration, work history, and Medicaid/state program enrollment prior to index incarceration
• All factors balanced after propensity weighting <=.25 SD/mean difference in groups
41

43
Community Days
• We find approximately 5 more community days (p=0.076) in 12 months for those on expedited Medicaid
• 3437/5 ~ $687/community day
44
Conclusions
• Preliminary results indicate that Expediting Medicaid increases access to services, thus increasing costs in the short run (1 year)
• While the program results in a greater number of community days, this amounts to a relatively high cost per day ($687) in the short run
45
Conclusions/Limitations
• If investments in health are made in the short run, the payoff in terms of reductions in hospitalizations may not be observed until beyond the 12 month window– 36 month analysis is pending; will also look at– 30 and 90 day results re criminal justice outcomes
• Days in the community is a crude measure, which does not reflect quality of life– Clinical and person-centered measures are not
available in our data46
Conclusions
• In summary, expedited Medicaid in Washington State led to:– shorter time without insurance coverage– Better access to services, especially
pharmaceuticals– Higher costs, in total and on most dimensions– A few more days in the community post-index
release– Slight but nonsignificant reduction in DOC costs
47
Comparisons & Implications• In both states, expedited Medicaid restoration led to
quicker and greater mental health service use• No strong effects re reduced criminal justice
outcomes & costs• Many controls went on to obtain Medicaid after
release so further analyses are needed to isolate overall effects of having vs. not-having Medicaid
• However, our current analyses suggest that Medicaid alone might not be enough to keep people with SMI out of criminal justice system
