Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: t=0 (first “in study” pain (NRS) assessment on scene) to 3, 5 and 10 min ;Secondary Objective: Evaluating the analgesic effectiveness (proportion of patients with a clinically relevant reduction of the pain score), speed of onset of analgesia, ease of use, time on scene, transportation costs and safety.;Primary end point(s): Change in mean pain intensity (NRS) over 10 min: Change from baseline (t=0; first “in study” pain (NRS) assessment on scene) to 3, 5 and 10 min using Mixed-Effect Model Repeated Measure (MMRM). ;Main Objective: This study aims at evaluating efficacy (in terms of superiority to) of low-dose methoxyflurane versus standard of care in the treatment of acute pain due to extremity injuries in the emergency medical services in the Netherlands. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Change in mean pain intensity (NRS) over 5 min Speed of action Proportion of patients with a clinically meaningful reduction in pain intensity score Satisfaction regarding convenience, treatment efficacy and adverse events Fulfilment of expectations Patients’Global Impression of Change Treatment costs of pain relief Safety;Timepoint(s) of evaluation of this end point: depending on the endpoint: Change in mean pain intensity (t=0 (first “in study” pain (NRS) assessment on scene) to 3 and 5 min Speed of action (t=0; first in study pain (NRS) assessment on scene, 3, 5 and 10 min pain (NRS) measurements) Proportion of patients with a clinically meaningful reduction in pain intensity score (t=0 first in study pain (NRS) assessment on scene) and t=10 min pain (NRS) measurements) other parameters will be measured once after 10 minutes, but before transfer to the Emergency Department | — |
