Summary View help for Summary
This study evaluated the Serving A Vulnerable Entity (SAVE) initiative operated by the Southeastern Pennsylvania Transportation Authority (SEPTA) Transit Police. The initiative tested whether pairing a uniformed police officer with a contracted civilian outreach specialist increased the likelihood that individuals experiencing homelessness, addiction, mental illness, or other vulnerability conditions would accept transportation to a treatment or shelter facility. Variables include histories between SAVE participants and vulnerable individuals, primary condition of vulnerable individuals, reasons for refusing treatment, and reasons for unsuccessful transport. Race, gender, and relative age of vulnerable individuals were also collected.

Study Purpose View help for Study Purpose
The study was motivated by the growing national interest in alternative crisis response models and the increasing overlap of police and public health responsibilities in urban settings. To that end, the study revolved around one research question: Does the presence of an outreach specialist increase the rate at which treatment conversations result in treatment initiation?
Study Design View help for Study Design
From June 2022 to June 2023 SAVE officers conducted 158 treatment conversations involving 165 individuals across Philadelphia's busiest transit stations. SAVE officer shifts were randomly assigned to either:
- Control: police officers working alone, or
- Intervention: police officers accompanied by a civilian outreach specialist.
A treatment conversation was defined as a focused, need-specific dialogue in which officers or specialists assessed vulnerabilities, identified suitable facilities, and offered transportation. The study examined two outcomes: agreement to transport (intermediate) and successful treatment initiation (primary). Quantitative analysis was complemented by 150 hours of field observation and semi-structured interviews with officers, specialists, and supervisors.
