E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To explore whether salbutamol improves the pain associated with renal colic, when added to the conventional pain relief for patients presenting to the emergency department with subsequently confirmed renal colic. |
|
E.2.2 | Secondary objectives of the trial |
To explore whether salbutamol improves the pain associated with renal colic, when added to the conventional pain relief for patients presenting to the emergency department with suspected renal colic.
To assess the feasibility of conducting a definitive phase III multi-centre randomised controlled trial (RCT) of the cost and clinical effectiveness of salbutamol as an analgesic adjunct for patients with renal colic when added to the standard analgesic regime in the ED.

Study Within A Trial:
SWAT TITLE: dOes ParTicipant InforMatIon ShEet Design affect the recruitment rate into an interventional trial? A Study Within A Trial (OPTIMISED)
SWAT Registration: This SWAT is registered as SWAT 32 on the MRC SWAT repository.
Objectives: The primary objective for this SWAT is to explore whether improving the readability of a participant information sheet (PIS) has an effect on the recruitment rate into an interventional trial. The secondary objective of this SWAT will be to assess the impact, or “value”, of the PIS in the decision making of the patient.
Outcomes: The primary outcome will be the proportion of patients who consent to take part in the interventional trial (known as the host study). Secondary outcomes will be qualitative measures, whereby consenting participants will provide feedback about the PIS they were provided. A questionnaire provided by Peter Knapp used in the “TRECA” study (a study of digital, multimedia resources used in recruitment to trials with children and adolescents) will be used to inform the development of a similar, decision making questionnaire to assess the impact or value of the PIS in the decision making of the patient. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome will be the difference in the change in pain scores (measured on an 100mm Visual Analogue Scale [VAS]) from baseline to 30 minutes post drug administration between trial arms in patients with "Confirmed Renal Colic". |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
30 minutes from time of IMP injection |
|
E.5.2 | Secondary end point(s) |
1. The difference in the change in pain scores (measured on an 100mm Visual Analogue Scale [VAS]) from baseline to 30 minutes post drug administration between trial arms in patients with "Suspected Renal Colic" 2. The difference in the change from baseline pain score to pain scores at the following time points between trial arms: 15min, 60min, 120min, 240min, and then four-hourly thereafter, until 24 hours post drug administration or hospital discharge (whichever happens first) in both of the above subgroups. 3. The difference in the change in qualitative pain description from baseline pain assessment to pain assessments at the following time points between trial arms as measured using the short-form McGill Pain Questionnaire: 15min, 30min, 60min, 120min post drug administration. 4. Frequency and dose of morphine during the first 24 hours from enrolment (including prehospitally) 5. Any other analgesics required and the timing of their administration 6. Length of hospital stay
