Abstract Body: Introduction:
Academic medical centers frequently operate across expansive geographic areas including inpatient units, outpatient clinics, and office buildings. While hospital-based teams are well-established for responding to acute clinical deterioration among hospitalized patients, there is often a response gap for non-admitted patients with emergent clinical needs. While some centers use prehospital providers to address this gap, their utility as support for hospital-based response teams during resuscitation events is less explored.

Hypothesis:
A dedicated, paramedic-based Campus Response Team (CRT) can reliably integrate with hospital-based response teams to provide safe, standardized resuscitation care for all patients.

Goals:
The primary aim of this retrospective study was to evaluate the effectiveness of CRT as primary responders for non-admitted patients, and a secondary goal was evaluating the effectiveness of CRT as clinical support for hospital-based response teams responding to admitted patients.

Methods:
A dedicated, paramedic-based CRT was implemented during peak operational hours (7:00 AM–7:00 PM, weekdays) as the primary responders for non-admitted patients, including visitors, outpatients, and staff. An inpatient scope of practice was developed for CRT to support hospital-based teams, and a standardized, Utstein-style data collection framework implemented. Over a seven-month period (November 2024 to May 2025), all CRT activations were reviewed, including screening for any reported adverse events.

Results:
During the seven-month study period, CRT responded to 693 events (364 non-admitted, 329 admitted co-responses), averaging 4.6 responses per covered 12-hour shift. Non-admitted responses were notable for 7 stroke alerts, 4 trauma alerts, and 2 cardiac arrests. In both non-admitted cardiac arrest events, CRT facilitated transfer to the emergency department with CPR in progress where return of spontaneous circulation was achieved. Admitted responses included 285 rapid response activations, 18 stroke alerts, and 6 in-hospital cardiac arrests. No adverse events were reported.

Conclusion:
A dedicated, paramedic-led CRT represents a feasible and complementary strategy for standardizing resuscitation efforts across both admitted and non-admitted patient populations. In health systems where outpatient volume may not justify a standalone team, integration with existing inpatient response infrastructure may enhance feasibility and resource efficiency.
