|
E.1.1.1 | Medical condition in easily understood language |
Severe pain after traumatic injury |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Injuries, poisonings, and occupational diseases [C21] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this trial is to determine whether paramedic administered ketamine or morphine provides more effective pain relief for patients reporting severe pain following trauma. This will be measured by using a 0-10 numeric rating scale and the Sum of Pain Intensity Difference (SPID). |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives of the trial are to assess the effects of the paramedic administered ketamine and morphine on patient outcomes up to 6 months post injury. Specifically on overall pain relief and patient experience, including tolerability and longer term outcomes. We will review the resource used and cost effectiveness of each drug.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Age 16 years or over - Patient reports a pain score ≥7/10 on a 0-10 NRS following acute traumatic injury - Intravenous or intraosseous access obtained - Determined by a paramedic to require IV morphine or equivalent
|
|
E.4 | Principal exclusion criteria |
- Known or suspected pregnancy - Unable to articulate severity of pain using the 0-10 NRS - Lack of capacity due to a reason other than pain - Ketamine or opioid analgesia prior to randomisation - Known contraindication to either ketamine or morphine as per the SmPC - Patient declines participation - Known prisoner |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Effectiveness of pain relief from randomisation to arrival at hospital as measured by Sum of Pain Intensity Difference (SPID) score (using a 0-10 numerical rating scale). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Following arrival at hospital. |
|
E.5.2 | Secondary end point(s) |
Effectiveness of pain relief and overall patient experience from randomisation to arrival at hospital - Total Pain Relief (TOTPAR) score - Time to perceptible analgesia - Time to meaningful analgesia - Time to peak analgesia - Duration of analgesia - Requirement for rescue analgesia - Proportion of patients with a pain intensity score below 4/10 (0-10 numerical rating scale (NRS)) on arrival at hospital - Vital signs (oxygen saturation, blood pressure, heart rate, respiration rate, Glasgow Coma Scale) - Patient Global Impression of Change on arrival at hospital
Incidence of side effects and adverse events - Airway: vomiting, aspiration, advanced airway management - Respiratory: desaturation, need for ventilatory support - Cardiovascular: arrhythmia, hypotension and hypertension - Neurologic: sedation, excitatory movements, adverse behavioural reactions - Other: nausea, allergic reaction
Resource use - Ambulance job cycle time (scene arrival to arrival at hospital) - Number of ambulance resources (technicians, paramedics, doctors and vehicles) in attendance - Cumulative IMP doses administered - CT scan use - Hospital or ICU admission - Length of stay ED, ICU, Hospital
Longer term outcomes - Chronic pain using BPI-SF at 3 & 6 months from randomisation - Health-related quality of life EQ-5D-5L and CSRI at 3 and 6 months from randomisation - Cost-effectiveness expressed in terms of incremental cost per quality-adjusted life year (QALY) gained using EQ-5D 5L and CSRI (at 3 and 6 months post randomisation) |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
