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.
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.

Non-transport of low urgency EMS case to hospital
Based on Karlovy Vary EMS audit data, there is 10% of low urgency cases treated and left on site by paramedics so far. So the primary outcome is to evaluate the rate of non-transports in common daily routine, when the doctor provides phone call consultation on request of paramedics (based on Karlovy Vary EMS protocol) to mandatory phone call consultation and audiovisual consultation with a EMS doctor. Therefore, the primary objective is to evaluate potential benefit audiovisual consultation with EMS doctor on the rate of patients left at home after treatment on site by paramedics.
Time frame: until 200 cases per group are collected, estimated time 6-8 weeks from the beginning of the study
The rate of repeated trips within 48 hours after the patient had been treated at home.
The co-primary safety outcome was repeated EMS trip within 48 hours after the patient had been treated at home. This outcome can confirm and compare the safety among study groups.
Time frame: until 200 cases per group are collected, estimated time 6-8 weeks from the beginning of the study
Qualitative analysis of subjective perception of phone call and audivisual consultation.
This analysis of subjective perception of each event in all 3 groups will be evaluated. The inevstigators will use Likert scales (1-excellent, 2-good, 3-sufficient, 4-insufficient) to compare phone and audivisual consultation in following parameters: clinical information transfer, situational context, safety of care. Surveys have to be filled and the patient opinion should be asked at the and of an transport or befere the crew leaves the patient on site. The EMS doctor will fill the survey immediately after the phone or audiovisual consultation is provided.
Time frame: until 200 cases per group are collected, estimated time 6-8 weeks from the beginning of the study
