Table 4 Study endpoints

From: Comparison of three regimens with inhalational methoxyflurane versus intranasal fentanyl versus intravenous morphine in pre-hospital acute pain management: study protocol for a randomized controlled trial (PreMeFen)

Primary endpoint

• Changes in pain score from T0 to T10

Secondary endpoints

• Changes in pain score from T0 to T5, T20, T30 and end of mission TED

• Need for additional analgesia not in the regimen of the allocated treatment group

• Differences in time arrival to administration of IMP registration of AE and SAE during study period until end of intervention

• Time from ambulance personnel arrival to first measure > 2 points reduction in NRS from baseline

• Change in level of sedation from T0 to T10 and T30

• Change in RR T0 to T10 and T30

• Change in SBP T0 to T10 and T30

• Likert scale of HCP satisfaction at end of mission

• Likert scale of patient satisfaction at end of mission

• Registration of AE and SAE during study period until end of intervention

Exploratory endpoints

• Analyze primary and secondary efficacy endpoints stratified by diagnosis or diagnosis groups

• Proportion of patient receiving rescue treatment related to procedures (reposition of fractures, relocation, etc.)

• Attempts of vascular cannulation access

• Change in NRS and time to a significant NRS reduction compared to level of competence

• Ambulance personnel competence and patient satisfaction

• Analyze primary and secondary efficacy endpoints stratified by level of troponin after ED admission and sign of ACS on ECG at scene

• Analyze AE and SAE in relation to concomitant therapy and other non-IMP determinants
