About this study

Official title: Audiovisual Consultations by Paramedics With an Emergency Medical Service Physician in Low Urgency Events: Randomised Controlled Trial

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.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: until 200 cases per group are collected, estimated time 6-8 weeks from the beginning of the study

Secondary outcomes (1)
  1. 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.

    Measured: until 200 cases per group are collected, estimated time 6-8 weeks from the beginning of the study

Model description
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) .
