Behavioral: opioid prescription
The intervention consisted of a randomized questionnaire presenting a clinical case of a patient suffering from severe abdominal pain. The control case was "As an emergency physician in an adult emergency department, you are presented with the following patient: The patient is a 39-year-old non-smoking male/female with a history of Meniere's disease and an allergy to Bactrim. He/she presents with abdominal pain that began abruptly 2 hours ago and has persisted despite taking NEFOPAM 45 minutes ago. This is his first episode. His/her vital signs are blood pressure 140/66, heart rate 91, pulse ox 97%, temperature 36.8°C. He/she rates his/her pain as 8/10 without any analgesic position. On clinical examination he/she presents with localized epigastric tenderness. The rest of the abdomen is soft, painless and depressed. There are hydro-aeriform noises. No diarrhea or vomiting. The rest of the clinical examination showed no abnormalities.". In the intervention case, patient had history of S

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Morphine prescription
Time Frame: through study completion, an average of 1 year
The proportion of patient for which physician would have prescribed morphine
through study completion, an average of 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Analgesic prescription between groups
Time Frame: through study completion, an average of 1 year
To compare analgesic prescription between groups
through study completion, an average of 1 year
factors associated with differences in management between groups
Time Frame: through study completion, an average of 1 year
identify factors associated with differences in management (urgency level, morphine prescription and computed tomography scan ordering)
through study completion, an average of 1 year
Differences according to patient and practitioner gender
Time Frame: through study completion, an average of 1 year
analyze the difference in morphine treatment prescribed according to patient and practitioner gender
through study completion, an average of 1 year

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 17, 2025

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
