ED to EPI: Using SMS to Improve the Transition From the Emergency Department to Early Psychosis Intervention

Study Overview
=================
Brief Summary
-----------------
Psychosis is a disabling condition that typically has its onset in adolescence and early adulthood. Many young people with psychosis have difficulty navigating services or are reluctant to engage in treatment until their illness becomes an emergency. Consequently, nearly half of all new psychotic disorders are diagnosed in the emergency department (ED). Despite the rationale and evidence for early psychosis intervention (EPI), around half of youth do not access these services. The investigators will use short message service (SMS)/text messaging, a low-cost, low-complexity, youth-friendly approach, to improve transitions in care from the ED and related acute services to EPI services, investigating the intervention's effect on attendance at the first consultation appointment, longer term service engagement, and system-level outcomes. The investigators will also evaluate cost-effectiveness and user perspectives of the intervention.

Detailed Description
-----------------
At the Centre for Addiction and Mental Health (CAMH), the investigators will recruit a consecutive series of 186 participants aged 16 to 29 referred by the CAMH ED and related acute services to CAMH's EPI program for a pragmatic randomized controlled trial of a 2-way SMS intervention involving reminders, psychoeducation, and check-ins. The primary outcome will be rate of attendance at the first consultation appointment assessed through chart reviews. Secondary outcomes will include indicators of long-term service engagement as well as symptoms and functioning 6 months following study enrollment and health service utilization for up to 2 years using administrative data from the Institute for Clinical Evaluative Sciences (ICES). Administrative data will be used for an economic analysis. Participants who receive the active intervention will be asked to complete a web-based survey evaluating their experience and a subgroup will be asked to participate in in-depth in-person qualitative interviews. Patients and family members with lived experience will be engaged in all aspects of the project, including shaping the intervention and study design. The investigators hypothesize that the intervention will result in increased rate of attendance at the first EPI consultation appointment, as well as improved longer-term engagement in outpatient EPI services compared to the sham comparator. Demonstrating evidence that this low-cost, low-complexity, youth-friendly intervention improves engagement in outpatient EPI services has the potential to improve long-term outcomes for young people with psychosis.

Design Details

Primary Purpose: Health Services Research
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Immediately after study enrollment, participants will be randomized using an electronic data management system to the active or sham intervention. Randomization will be stratified by sex and referral source (main emergency department vs. Bridging Clinic vs. inpatient unit), using a computer algorithm to perform a blocked randomization assignment within strata.
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Active SMS Intervention<br>Participants assigned to the experimental arm will receive the active SMS intervention. Participants in the active intervention group who consent to participate will be asked to complete a web-based survey. Based on survey findings, purposive sampling will be used to select a subsample of 12 to 20 participants for qualitative interviews. | Behavioral: Active SMS Intervention<br>* Welcome message letting participant know they will be contacted to book an appointment, followed by appointment reminders and other clinic information, psychoeducational materials, and a distress check-in with two-way feedback to their care team, all sent by SMS/text message at the participant's preferred time of day. If they indicate that they are in high distress, or they request, their care provider will be notified and asked to reach out to them. They will also receive crisis resources.The intervention will continue until the patient attends the first consultation appointment, or for up to 30 days if the patient does not attend, which reflects the program's practice of closing referrals for non-attending patients.<br>|
| Sham Comparator: Sham SMS<br>Participants assigned to the sham comparator will receive the sham SMS intervention. They will not be re-contacted. | Behavioral: Sham SMS<br>* Single welcome message letting participant know they will be contacted to book an appointment.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Attendance at the first early psychosis intervention (EPI) consultation appointment | Attendance at the outpatient EPI consultation appointment will be assessed through chart reviews and categorized as: Yes - attended at original appointment time, Yes - attended at later date within 30 days, No - did not attend appointment within 30 days. | 30 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Service engagement - absolute drop-out | Absolute dropouts will be assessed through chart reviews and categorized as: Still in EPI treatment, Not accepted for EPI treatment, Accepted for EPI treatment but transitioned to local services, Accepted for EPI treatment but disengaged, or Other. | 6 months | 
| Service engagement - Service Engagement Scale (SES) | The Service Engagement Scale is a brief, validated, clinician-rated tool designed to measure engagement with community mental health services. In 14 items, it assesses patients' availability for treatment, collaboration, help seeking behaviors and treatment adherence on a four-point Likert scale with total scores ranging from 0-42, and higher scores indicating difficulties in service engagement. The Service Engagement Scale total score and treatment adherence score will be extracted through chart reviews. | 6 months | 
| Change in psychotic illness as measured by the Clinical Global Impression (CGI) | The Clinical Global Impression (CGI) is a clinician-rated measure of the patient's symptom severity and treatment response prior to and after initiating an intervention. It includes subscales for Severity and Improvement. The Clinical Global Impression - Severity scale ranges from 1-7 with higher scores indicating higher severity of illness, relative to other patients with the same diagnosis. The Clinical Global Impression - Improvement scale ranges from 1-7 with 4 indicating no change, 1 indicating very much improved, and 7 indicating very much worse relative to the patient's illness at the beginning of the intervention. Scores will be extracted through chart reviews. | 6 months | 
| System-level outcomes: emergency department visits | Number of emergency department visits, extracted from provincial administrative data held at the Institute for Clinical Evaluative Sciences (ICES) | 6 months and 2 years | 
| System-level outcomes: mental health hospitalizations | Number of mental health hospitalizations, extracted from provincial administrative data held at the Institute for Clinical Evaluative Sciences (ICES) | 6 months and 2 years | 
| System-level outcomes: days in mental health hospitalizations | Number of days in mental health hospitalizations, extracted from provincial administrative data held at the Institute for Clinical Evaluative Sciences (ICES) | 6 months and 2 years | 
| System-level outcomes: outpatient mental health visits with primary care provider | Number of outpatient mental health visits with primary care provider, extracted from provincial administrative data held at the Institute for Clinical Evaluative Sciences (ICES) | 6 months and 2 years | 
| System-level outcomes: outpatient mental health visits with psychiatrist | Number of outpatient mental health visits with psychiatrist, extracted from provincial administrative data held at the Institute for Clinical Evaluative Sciences (ICES) | 6 months and 2 years |
