Brief summary

The primary goal of this study is to find out if patients who speak with an EMS physician over the phone are less likely to refuse care compare to patients who do not speak with an EMS physician.

Detailed description

This study aims to assess the impact of direct physician communication on patients' decisions to refuse EMS transport. The research approach is designed to measure the influence of physician interaction on patient transport decisions in a prospective model. By conducting this research, the study team hopes to provide evidence-based recommendations for EMS protocols regarding patient engagement and refusal management.

Interventions

Every other month will be randomized to either Physician Consultation or Standard of Care. During the months designated for Physician Consultation, direct communication between the patient and a designated physician by phone will be implemented when a patient refuses transport in cases where the EMS clinician feels that physician consultation is warranted for further guidance. The physician will attempt to address patient concerns and provide additional medical advice.

BEHAVIORALStandard of Care

Every other month will be randomized to either Physician Consultation or Standard of Care. During the months designated for Standard of Care, physician intervention will not be provided. For safety reasons, if physicians or EMS MEDIC clinicians feel that speaking with the patient is important to provide additional clinical benefit, they may do so without hesitation and can override the designated intervention month.
