Brief Summary

The aim of this randomized, controlled trial is to study the effectiveness of a potential new form of pre-arrest jail diversion for people with serious mental illnesses: the Police-Mental Health Linkage System. In the case of an encounter with a police officer, for half of the participants, during the background check, a message will notify the officer that the subject has mental health considerations. The notice contains a phone number of a provider working at the mental health clinic where the subject is receiving services, who can provide telephonic support to the officer. For the other half of participants, the message will not appear to the officers in the case of an encounter.

Detailed Description

Fragmentation between mental health (MH) and criminal justice (CJ) systems leads to many persons with serious mental illnesses (SMI) being arrested/incarcerated when MH treatment would be more appropriate. As defined by SAMHSA, the disorders typically meeting criteria for SMI include schizophrenia, schizoaffective disorder, other psychotic disorders, major depressive disorders, and bipolar disorders. This study aims to test the effectiveness of a new police-MH linkage system. This study is a randomized, controlled trial to study the effectiveness of our new services-level intervention. Our "linkage system" piggybacks on the Georgia's criminal justice information system such that a police officer running a routine inquiry (similar to a background check) during an encounter with a consented and enrolled outpatient with a serious mental illness will receive an electronic message to call for information that might assist them. The officer can immediately call and connect to a Linkage Specialist (licensed mental health professional in the local public mental health system where the patient is or was enrolled in outpatient care), who provides brief telephonic support, information, and advice to the officer. The investigators have shown, in the recently completed NIMH-funded R34 intervention development project, that in some cases, a discretionary arrest (i.e., not obligatory, no violence involved) is replaced by informal resolution in light of the new information provided to the officer via the inquiry message and telephonic support from the Linkage Specialist. Furthermore, even more common than jail diversion, many patients involved in a police encounter were reconnected to care (after having fallen out of care and becoming symptomatic). This trial aims to determine whether or not the new linkage system is effective for reducing arrests and reducing discontinuities (gaps) in outpatient mental health care services. Partnering with our CJ partner, Georgia Bureau of Investigation (which houses Georgia's CJ databases/information system), as well as 4 public MH agencies covering 25 counties in Georgia, the investigators will conduct a randomized trial of the linkage system involving 1,600 outpatients with SMI. The investigators will test the hypotheses that patients randomized to the linkage system (as compared to those randomized to a database that does not generate the MH notice and phone number) will: (1) be less likely to be arrested, (2) have fewer arrests (both based on administrative (rap sheet) data provided by GBI), and (3) be less likely to have gaps in outpatient MH services, as evidenced by fewer absences from care of >3 months (based on data from the MH agencies' EMRs).

Study Groups

Intervention

The Police-Mental Health Linkage System

In the case of an encounter between law enforcement and subjects randomized to this group, the officer will receive a notice disclosing that the participant receives services in a mental health clinic and that he/she has the opportunity to call to speak with a mental health professional.

Group Type: EXPERIMENTAL

The Police-Mental Health Linkage System

Intervention Type: OTHER

When, during an encounter, the police officer decides to call the number provided in the notice, the Linkage Specialist (a licensed mental health provider from the mental health service where the subject was recruited, who has access to the clinic's EMR) can provide telephonic support to the officer.

No Intervention

In the case of an encounter between law enforcement and subjects randomized to this arm of the study, the officer will not receive any notice.

Group Type: NO_INTERVENTION

No interventions assigned to this group
