Clinical Trial Summary
SOS will identify evidence based best practices consistent with Zero Suicide's six specific
recommended clinical actions (A.2.) and use them to develop standardized clinical protocols
for each care setting, clinical unit, population serviced, and clinical discipline. Using
Lean CQI, the investigators will tailor, implement, and improve adherence to these protocols.
To support feasibility, SOS will use a phased roll out and a hub-and-spoke design. The
intervention targets will be suicide-related clinician behaviors. The investigators will
aspire to adopt best practices and measure all six recommended performance elements; however,
for feasibility, the research evaluation will focus on suicide risk screening, safety
planning, means restriction counseling, and post-acute care follow-up calls. The primary
patient outcomes will be suicide risk identification, suicide, suicide attempts, and
suicide-related emergencies requiring acute care. The investigators will examine potential
mechanisms of action and moderators, and conduct a cost effectiveness analysis of SOS versus
usual care. The investigators will employ a stepped wedge design and follow individuals for 6
to 54 months. Outcomes, clinician behaviors, and other variables will be gathered through:
(1) EHR data extraction, (2) claims data from UMMHC and the MA All Payer Claims Database, (3)
random medical chart abstractions, (4) MA state vital statistics and National Death Index
(NDI), (5) clinician surveys, (6) Lean evaluations and process observations, and (7) patient
fidelity interviews. Data will be analyzed using generalized linear mixed models.
Description:
The System of Safety (SOS) project will catalyze and expand the investigators existing
efforts to transform suicide risk detection and suicide prevention across the UMass Memorial
HealthCare system (UMMHC), the largest healthcare system in central Massachusetts
representing a catchment area of 1.06 million people. This effort will span emergency
department, inpatient, and primary care settings; engage medical and behavioral health
clinicians; target adults and children; and support integration and collaboration across the
entire system to provide a 360-degree safety net for patients at risk for suicide. Building
on our previous and ongoing work, Zero Suicide's Seven Essential Elements of Care (Essential
Elements) will be the foundation for an innovative continuous performance improvement (CQI)
hub-and-spoke model whereby a central System Hub will work with Local Hubs and Spokes
representing each setting and clinical unit. SOS will evolve over three phases. Phase 1
(months 1 - 12) will start with the emergency departments across the four UMMHC hospitals;
Phase 2 (months 13 - 30) will extend the efforts to the inpatient medical and psychiatric
units; and, Phase 3 (months 31 - 48) will expand to primary care settings. Overall, 39
clinical units will be engaged.
Consistent with central CQI tenets and the Zero Suicide model, the investigators will create
protocols using best-practice approaches to identifying, assessing, managing, and intervening
with suicidal patients while tailoring the approach to the particular clinical unit's unique
needs and population. Units will learn from one another through regular collaborative work
sessions, retreats, and cross departmental sentinel case reviews of suicides and suicide
attempts. Fidelity to key components of the protocols will be measured.
The investigators will use a stepped wedge design with cluster randomization of clinical
units, stratified by setting. Within each setting (Phase), the study population will consist
of all patients seen in any of the clinical units during the pre-specified observation period
before (Control) or after (Intervention) the unit's implementation start date. The
investigators will follow these estimated 310,000 patients from their 1st encounter with a
clinical unit through 6 months after Phase 3 ends (month 54). The investigators Aims assess
the effect of SOS on its intervention targets (clinician behaviors) and on patient outcomes,
using a system-level analytic strategy. The Specific Aims are:
Aim 1: Examine the impact of the SOS intervention on clinician-administered, standardized
suicide risk screening and suicide risk identification across settings and clinical units.
H1: Likelihood of clinician-administered standardized suicide risk screening (an intervention
target) at the time when a patient enters the study will increase monotonically with time
since study initiation.
H2: Likelihood of suicide risk identification (patient outcome) at the time when a patient
enters the study will increase monotonically with time since study initiation.
H3: The increasing likelihoods of screening and identification are attributable to SOS
implementation.
Aim 2: Examine the impact of SOS on suicide related outcomes across settings and clinical
units.
H4: As SOS is implemented across more settings and clinical units, the likelihood of
receiving a best practice suicide prevention intervention by a clinician (intervention
target) will increase among newly identified at-risk patients. This includes, but is not
limited to, collaborative safety planning, means restriction counseling, and a post-acute
care follow-up telephone call within 24 hours of discharge.
H5: SOS implementation will decrease the likelihood of suicide, suicide attempt, or
suicide-related emergency requiring acute medical attention (patient outcomes) among newly
identified at-risk patients.
H6: "Dose" of exposure to SOS will mediate the effect of SOS noted in H5.
Exploratory Aims: The investigators will also evaluate SOS from different perspectives by:
A: Exploring potential moderating and mediating factors, and potential mechanisms of action,
such as:
EH1: Supportive organizational characteristics (e.g., embedded behavioral services on site,
providing regular clinician-level performance feedback) will promote higher adherence to SOS
implementation.
B: Exploring the population level effect of SOS on a subgroup of UMMHC patients that
constitutes an Accountable Care Organization (ACO). For example, the investigators
hypothesize that:
EH2: Suicide-related outcomes measured at the entire ACO population level (not just those
encountering a clinical unit during the study period) will decrease monotonically during the
study period (3-month increments).
C: Exploring the cost-effectiveness of the SOS intervention compared to usual care. The
investigators hypothesize that EH3: The cost of SOS will be < $50,000/ quality-adjusted life
year saved, a commonly used threshold.
