Recovery housing is a substance-free group home for those exiting drug and alcohol treatment. Individuals live in a recovery-focused environment with others traveling the same journey. Ohio Recovery Housing (ORH) creates and maintains standards of excellence for recovery housing in the state. Each house decides how it operates, with four different "levels" of housing available. These environments have the potential to help build a strong foundation in recovery to improve health, employment, and housing outcomes.

ORH and LEO will launch a quasi-experimental study to measure the impact of recovery housing for individuals with substance use disorders. The design relies on variation in the availability of program spots to identify effects. Invitations to join a home will come from a waitlist. As the length of the waitlist is unrelated to applicant characteristics, movement off the waitlist can be considered essentially random. The research team will compare those who receive services to those who do not.

The researchers hypothesize that those who participate in recovery housing will have improved health, employment, and housing outcomes compared to individuals who do not receive recovery housing services.

The impact of ORH's recovery housing program will be evaluated using a quasi-experimental research design.

1. Individuals referred to or interested in recovery housing services typically contact an individual recovery home, either by phone or in person. At that time, ORH operator staff will screen individuals using existing eligibility criteria to determine if the individual would be a good fit for their recovery housing program. For example, clients must agree to follow house rules, live in a group environment, and be substance free. If they are unwilling to agree to these terms, they are not eligible for the program.
2. Interested clients will then complete an intake survey that collects basic demographic information about the client, some data about their history of substance use, and some economic data. This data is collected online using survey software, such as Qualtrics, so the data will be recorded electronically for all referred individuals. People that visit a home in person will be asked to fill out the survey on a tablet or computer. Those who call the home will answer these questions verbally over the phone, and the operator will complete the online survey on their behalf. The operator will explain the study to those who are deemed eligible for services and then obtain informed consent for study participation. If the operator is unable to answer individuals' questions, the operator will refer clients to the research team using the contact information provided on the informed consent form. For consenting individuals, identifying information will be collected for the purposes of tracking outcomes in administrative data and conducting a follow-up survey.
3. Eligible clients will be placed on a waitlist for the recovery housing program if there is not available capacity at the time they approach the program. If a program slot does not become available within two weeks, the individual will be removed from the waitlist and referred elsewhere. Individuals who are eligible for recovery housing based on the criteria set by ORH will have the same chance of receiving recovery housing services regardless of whether they consent to be in the study. All eligible individuals will be placed on the waitlist for housing in the order in which they arrive. Being part of the study will have no effect on an individual's ability to participate in recovery housing, and they will be clearly informed of this during the informed consent process.
4. Individuals for whom there is a recovery housing program slot available will be invited to move into the recovery home and receive specific provider services. All recovery housing providers in the ORH network will provide a healthy and safe environment, support for recovery planning, peer support services, referral to additional services in the community as identified by the resident's recovery plan, formal and informal recovery activities, and connection to mutual aid groups. Consenting individuals who are given a placement in recovery housing may choose to withdraw from the study at any point, including after they have been accepted into a recovery home. Withdrawing from the study will have no bearing on the services offered, nor the individual's relationship with ORH or affiliated providers.
5. Individuals for whom there is no program slot available will be assigned to the control group and will not have access to ORH recovery housing services. These individuals will be provided a list of other possible services elsewhere. Individuals placed in the control group will be able to re-enter the waitlist by contacting the recovery house to which they applied. Based on information provided by the recovery housing organizations, this will likely be a rare situation. For the purposes of analysis, individuals will be placed in the treatment or control group based on their assignment from the first time they are on the waitlist.
6. The research team will track outcomes of those who consented to be part of the study in administrative data sources to learn about housing stability, hospitalizations, and employment. These administrative records include inpatient stays and emergency department visits (collected by state Medicaid programs), earnings from employment as recorded by state unemployment insurance systems, and address histories from private address tracking services such as Infutor.
7. The data sharing agreements that would allow us to use these administrative data sources are in process. For example, LEO is currently working on data sharing agreements with the Ohio Department of Job and Family Services and the Ohio Department of Medicaid to obtain data on outcomes.
8. There are some key outcomes that cannot be derived from administrative sources. For example, sobriety among participants in the control group can only be quantified through an in-person survey. During the intake survey, personally identifiable information will be collected to perform a follow-up in-person survey.
