Determining the Populations of Focus
By reviewing this section of the guide first responders will be able to:
1. Understand the important challenges and promising practices that other programs have used to decide who their deflection and diversion programs will serve
2. Recognize the public health principles that guide delivery of services within deflection and diversion to a wide range of individuals who use drugs
3. Consider issues with inclusion and exclusion criteria for each component of your deflection and diversion program
One of the first key decisions deflection and diversion program implementers must make is to define the population that will be eligible for participation. Two principles guide this determination.
1. Deflection and diversion programs seek to provide services to the broadest population of individuals at risk for drug abuse. The initial emphasis for programs had been opioid use, but now, most programs address all substances, including alcohol, mental health disorders, co-occurring disorders, and other social issues.
2. All individuals are deserving of services. There is no public health justification for excluding individuals based on criminal history or other justice-system statuses.
Section A: Define Eligibility Requirements & Populations of Focus
For example, a post-overdose follow-up program will narrow the population to those that have experienced a recent non-fatal overdose. An intake program will have the broadest target population because it aims to create pathways to treatment for most individuals with substance use disorders that contact program sites for assistance. Certain street outreach programs might focus on areas known to have populations of people who use drugs with a different set of criteria for inclusion. Overtime, many programs incorporate multiple pathways to broaden their reach.
Section B: Select Exclusion Criteria
i) existing warrant status
ii) offense types committed at point of contact, if applicable
iii) other existing supervision status (e.g., parole or probation), and
iv) criminal history prior to point of contact.
There is little guidance about the appropriateness of these criteria for program success.
Section C: Warrant Status
Promising Practice Recommendations
Avoid including warrant status as exclusion criteria, particularly for intake, outreach, and overdose follow-ups. Checking warrants may be more appropriate for pre-arrest diversion, and the practice is virtually unavoidable in most post-arrest diversion procedures.
If you are required to check warrants due to state or local policy, have a process in place that allows for discretion from higher ranking staff or one that would allow the local court to re-docket cases when possible.
The Hope Not Handcuffs program procedures explicitly state that the warrants “may” affect eligibility and that shift supervisors have the discretion to allow participation based on several factors.
The Safe Passage program in Illinois had a process in place for officers to contact the state’s attorney, which resulted in most of the existing warrants being vacated.
Section D: Offense Types at Point of Contact
Individuals might be in possession of drugs or drug paraphernalia when they arrive at an intake site or when contacted through outreach activities in public or private spaces. Intake and outreach programs should minimize barriers to access treatment and recovery and should not exclude individuals who are voluntarily seeking resources, while in possession of drugs or drug paraphernalia. However, implementing agencies must decide on the appropriateness of diversion for certain offenses in addition to drug possession when conducting enforcement activities and pre-arrest diversion practices.
Promising Practice Recommendations
Avoid overly restrictive exclusion criteria around offenses committed during the contact. For example, possession of illegal substances or paraphernalia offenses should not be added to exclusion criteria for any deflection components of your comprehensive model. This ensures a more inclusive and effective approach, addressing underlying issues and promoting harm reduction within the framework of diversion.
Assess the offense types added to exclusion criteria with data from existing sources. Existing pre-implementation arrest data is a window into determining how exclusion criteria will affect the number of people eligible for deflection and diversion programs.
Build discretion into your exclusion criteria based on offense type criteria. For example, the MARI program in Madison, WI, allows exceptions with approval from higher-level staff. For more information, refer to the policy and procedure section.
