Improving Mental Health Treatment for Individuals in Crisis Interacting With the Criminal-Legal System
What this study is about
The proposed Center will leverage burgeoning real-time data linkage capabilities among health systems, Medicaid payors, and criminal legal (e.g., jail booking data, jail release data) systems, to identify individuals coming in and out of jail for suicide assessment and prevention, and to better coordinate care across these disparate systems.
View original scientific description
The proposed Center will leverage burgeoning real-time data linkage capabilities among health systems, Medicaid payors, and criminal legal (e.g., jail booking data, jail release data) systems, to identify individuals coming in and out of jail for suicide assessment and prevention, and to better coordinate care across these disparate systems. This Center will advance the fields of suicide prevention and criminal legal system-based mental health by solving a well-known, central problem in both fields: the inability to track and intervene with individuals moving in and out of both and often multiple systems. The goal is near-term reductions in the U.S. suicide rate.
Interventions
OTHER
Treatment as usual (TAU)
TAU patients will be identified using "targeted limited chart review methods" used in our prior studies, "scraping" clinical notes in the EHR for criminal legal involvement. Initial Identification terms, "police", "arrest", "court", "summons", "jail", and "crime" will be used to identify candidates for police involvement, downloading the sentence in which the keyword appeared and the sentence before and after. Next, an iterative process of editing of the search terms will be conducted to remove patients with negation of the keyword ("did not commit a crime"), and other sentence characteristics that generate false positives ("cardiac arrest"). Samples of the resulting dataset will be taken, accuracy assessed by examining the surrounding sentences, leading to further iterations and repetition of the process until a high level of accuracy is achieved.
OTHER
FSJS
Documentation and follow-up by the Cambridge Police Department (CPD) for all mental health-related police calls, including involuntary and voluntary Emergency Department admissions; Established partnerships with city departments, healthcare systems, clergy, courts, businesses, and mental health advocates to ensure timely engagement in mental health treatment and community-based services; Required 40 hours of officer crisis intervention training (CIT), and additional sessions on trauma- informed policing, mental health, race, and crisis negotiation; and Staffing of sworn and civilian staff including specially-trained officers designated to work with individuals living with mental illness, homelessness, and substance abuse.
OTHER
FSJS+Navigator Intervention
The FSJS+Navigator intervention adds an Emergency Department (ED)-based Systems Navigator, a community health worker with lived experience (as family member or patient) with criminal legal and mental health systems, to the FSJS. This navigator will enhance communication between Cambridge Police Department (CPD), Cambridge Health Alliance (CHA), and community agencies by being the needed "point person" within the healthcare system (the FSJS intervention only has a CPD-based social worker) to maintain communication to improve mental health services and prevent deeper legal involvement. The Navigator engages with the FSJS process in step i) of the above sequence, engaging the patient in the CHA ED and obtaining consent. The Navigator then discusses the case with the presenting CPD officer, and relays critical information about the context of the service call to ED staff. Next, the Navigator will administer the baseline CAT-MH/SS and assess additional needs (employment, housing, food).
Primary outcome measures
Past-year medically treated suicide attempt at baseline and 12 months
Time frame: Baseline and 12 months
Number of participants with a past-year medically treated suicide attempt. This will be measured at baseline and 12 months will be collected using the electronic health record (EHR) data.
Suicide Severity and Behaviors using Computerized Adaptive Test Suicide Scale (CAT-SS) at Baseline and 12 Months
Time frame: Baseline and 12 months
The CAT-SS measures Severity of Suicide Risk will be assessed using CAT-SS, providing severity on a 0-100 point scale, and risk-stratification to negligible, intermediate and high risk. It is highly sensitive and specific to the Columbia Suicide Severity Rating Scale, and predicts future suicide events with high precision and accuracy.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Treatment as Usual (TAU) arm
- Cambridge Health Alliance (CHA) patients from the cities other than Cambridge considered to be in the "catchment area" of CHA (Everett, Chelsea, Somerville, Medford, Malden, and Winthrop)
- Ages 18-100
- Identified as having police involvement between 2009 and 2025. Treatment as Usual patients will be identified using "targeted limited chart review methods" used in our prior studies, "scraping" clinical notes in the Electronic Health Records for criminal legal involvement. Initial Identification terms, "police", "arrest", "court", "summons", "jail", and "crime" will be used to identify candidates for police involvement, downloading the sentence in which the keyword appeared and the sentence before and after. Next, an iterative process of editing of the search terms will be conducted to remove patients with negation of the keyword ("did not commit a crime"), and other sentence characteristics that generate false positives ("cardiac arrest"). Samples of the resulting dataset will be taken, accuracy assessed by examining the surrounding sentences, leading to further iterations and repetition of the process until a high level of accuracy is achieved.
- Cambridge Health Alliance patients from Cambridge
- Ages 18-100
- Individuals who have come into contact with the Cambridge Police Department (as identified in the FSJS data) between 2009 and 2025.
- FSJS+Navigator arm
- Recruited during the study period in the CHA ED
- Ages 18-100
- Individuals who are brought into the Emergency Department under police supervision (excluding individuals currently incarcerated)
- involuntarily brought to the Emergency Department for psychiatric evaluation because they are considered to be a risk to themselves or others (MA Law 123(12)); or
- the subject of a police call for service for a mental health issue who are willingly admitted to the Emergency Department
Exclusion criteria
- Treatment as Usual (TAU) arm
- Cambridge Health Alliance patients residing in the City Cambridge are excluded from the TAU arm

- Any individual incarcerated at the Middlesex Jail/Prison that has not been released by the end of the period of data collection (December 31, 2025).
- Cambridge Health Alliance patients outside of Cambridge will be excluded from the FSJS arm
- Under the age of 18
- Any individual incarcerated at the Middlesex Jail/Prison that has not been released by the end of the period of data collection (December 31, 2025)
- FSJS+Navigator arm
- Under the age of 18
- Any individual who becomes incarcerated during the course of the study
- Individuals who enter the Emergency Department not under police supervision
- For example, individuals will be excluded who voluntarily come to the ED seeking psychiatric care because they feel they may be a risk to themselves or others

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
