Official title

Implementing and Sustaining Critical Time Intervention (CTI) in Case Management Programs for Homeless-experienced Veterans (PII 21-285)

Overview

The VA Grant and Per Diem (GPD) case management aftercare program provides six months of case management for homeless-experienced Veterans undergoing housing transitions. This Partnered Implementation Initiative (PII) proposes to implement and evaluate Critical Time Intervention (CTI)-an evidence-based, structured, and time-limited case management practice-in 32 GPD case management aftercare sites across the nation.

Detailed description

The VA Grant and Per Diem case management (GPD-CM) program provides six months of case management for homeless-experienced Veterans (HEVs) undergoing housing transitions. At present, no specific case management paradigm is required in the GPD-CM program, resulting in practice variation across sites. This Partnered Implementation Initiative (PII) implements Critical Time Intervention (CTI)-an evidence-based, structured, and time-limited case management practice-at 32 VA GPD-CM sites. The investigators will use the Replicating Effective Programs (REP) implementation bundle to support CTI implementation at all 32 sites. Half of these sites will also receive 9 months of external facilitation (enhanced REP) as additional support for CTI implementation. In a type 3 hybrid trial, the investigators will use mixed methods to examine the impacts of REP versus enhanced REP. Using trial data, the investigators will develop a business case analysis and implementation playbook for the investigators' program partners to support continued CTI spread and sustainment in the GPD-CM program.

Interventions

  • Behavioral Critical Time Intervention
    An evidence-based, structured, and time-limited case management practice
  • Other External Facilitation
    Site-specific support to help sites develop tailored plans to implement CTI.
  • Other Replicating Effective Programs
    A stakeholder-informed training and technical assistance implementation strategy

Primary outcome measures

  • Fidelity to CTI [Time frame: 12 months after implementation start]
  • Sustainment of CTI [Time frame: 18 months after implementation start]
  • Dollars spent delivering CTI at each site [Time frame: Between 6 and 18 months after implementation start]
Secondary outcome measures (6)
  • Housing stability [Time frame: Between 6 and 18 months after implementation start]
  • Cost of CTI as Implemented [Time frame: Between 6 and 18 months after implementation start]
  • Hospitalization rates [Time frame: Between 6 and 18 months after implementation start]
  • Cost of Implementation Strategies [Time frame: Through study completion, 4 years]
  • Return on Investment (ROI) of CTI [Time frame: 6-, 12-, and 18-months after GPD case management program enrollment]
  • Outpatient service use [Time frame: Between 6 and 18 months after implementation start]
