Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study investigates safety and efficacy of the use of audiovisual consultations of emergency medical service (EMS) doctor by paramedics for low urgency events in areas covered with paramedic crews only from emergency medical service stations with distant access to hospital.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will be realized on Karlovy Vary EMS areas covered with paramedic crews only from emergency medical service stations with distant access to hospital. Each call on emergency line during 6 weeks study period will be assessed for eligibility. If deemed as low urgency, the event will be randomised into 3 groups. CONTROL group: routine operation of paramedic crew with optional consultation with a doctor over the phone. In the PHONE group and in the VIDEO group, there will be a mandatory consultation of a doctor over the phone or by audiovisual constultation, respectively. The primary outcome of the study is the percent of patients treated on site without the need of hospital transfer. The secondary safety outcome is to evaluate repeated ambulance trips within 48 hours after the patient had been treated at home. Moreover, a qualitative analysis of subjective perception of the event by the patients, paramedic and consulting doctor using the Likert scales will be performed by survey at the end or immediately after the event.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Low urgency emergency calls are randomised by call-taker of dispatching center to 3 groups: routine prehospital emergency care without optional phone call consultation (1), with mandatory phone call consultation with base physician (2), with mandatory audivisual consultation with base physician (3). Power analysis. Based on available data prior to the initiation of the study, 10% of patients after low acuity calls were treated on site. The hypothesis that the video consult would lead to doubling this percentage will be investigated. In order to have 80% probability to confirm this at p \< 0.05, we would need 200 subjects per group. Planned interim analysis will be after 4 weeks of study (aprox. after 600 eligible cases) .

3. dedicated doctor of Karlovy Vary EMS will be available for consultation during his shift.

Exclusion Criteria

1. need for escalation of the care: paramedics' requirement for the doctor to arrive at the scene of intervention,
2. consulting doctor is not available for the study at the moment of randomisation,
3. consultation with other than trained and for study dedicated doctors,
4. patient - crew language barrier,
5. study refusal by the patient or legal representative, or refusal of audiovisual consultation,
