Functioning of scientific committee
Main goals
Revision of the content of the application in the light of available scientific evidence over a 3-year cycle.
Requests from our users
The progression of scientific evidence

Committee directors
Roles:
• Determine the quarterly objectives of the committee with the help of the general manager and his members
• Determine committee members
• Distribute tasks to members to achieve the set objectives
• Schedule meetings to resolve impasses and ensure that objectives will be met
• Ultimately responsible for the committee meeting its objectives

Volunteer meetings
The volunteer meetings are scheduled four times a year. The committees present what they have accomplished in the last three months and determine their objectives for the next quarter.

Process : content management
Adding content to the EZResus app is done with extreme rigor. All members involved are aware of the immense responsibility associated with this process. The process for adding a new medication or reviewing a medication follows the same steps. The only difference is that revision often requires less discussion than adding a new medication.

Collaboration platform
We use the “Monday” collaboration platform for the management of tasks related to the content of the application.

1st step: literature review
The first step is the entry of a new medication and its indication. A literature review is assigned to a physician and a pharmacist. Role of the physician:
• Specify the dose according to the clinical indication according to the literature
• Identify relevant studies to include supporting the dose
Role of the pharmacist:
• Enter drug-specific information
• Available medication concentrations
• Compatibility, diluant type
• Administration speed
• Administration specifics
• Determine minimum and maximum dose
• Double-check the dose determined by the physician
All of these entries are made at a specific place in the “Monday” platform.

2nd step: group revision
Step number 1 often leads to very specific questions where the literature is uncertain or conflicting about the best way to administer a medication. These decisions are made based on the expertise of the rest of the team. At this stage, the content director schedules a meeting with its members to present the medications that have been reviewed in the first stage. The team makes final decisions regarding the information to be entered into the application.

Step 3: entry of clinical data in the back-end
Once the medications have been reviewed as a group, they are entered in the backend. As a security measure, only content directors and the general manager have access to the back-end of the application. Medications are entered in an “inactive” mode to ensure there is no impact on content viewable by our users.

Step 4: testing
The medications are tested in a test version of the app by two external testers. These two testers must not have participated in any prior discussion in connection with these medications. This procedure limits potential biases and ensures that we have “a fresh look” at this new medication.

Step 5: final revision
Once the two external testers have approved the new medication, it goes into final review. At this point, the general manager approves each medication and switches them to “active mode”. This acts as the last filter before the medication is available to users.

Step 6: review in “active” mode
A final brief review is performed once the medication is in “active” mode.

• Reichman’s emergency medicine procedures 3th edition
• Textbook of pediatric emergency procedures, King 2018
• Fleisher & Ludwig’s textbook of pediatric emergency medicine

Estimation of weight
Ideally, the exact weight of the child should be entered into the app for a more accurate calculation of the different doses.
If age is entered, calculations are made by using the “Best Guess Method”
• < 12 months: weight (kg) = (age in months +9) / 2
• 1-5 years: weight (kg) = (2 x age in years) +10
• 5-14 years: weight (kg)= 4 x age in years
If height is entered, calculations are made by using the “Broselow-Luten Tape system” • Note that this rule tends to underestimate the weight of patients in developed countries

Pediatric particularities
We had to make some editorial choices in relation to the differences in practice between the emergency room and pediatric intensive care. In order to limit the amount of volume infused in children with low weights, it is common practice in intensive care to use “syringe drivers”. Unfortunately, these devices are not available in all emergency rooms, especially in remote areas. We have therefore established safe recipes by diluting the doses in small volumes (25mL). It should be kept in mind that the administration of several medications in a low weight patient can represent a considerable amount of volume. Clinical judgment should always prevail.

Obesity references

General
EZResus improves the calculation of medications in obese patients. If all the information is entered, the application recognizes that the patient is obese and calculates the appropriate medication dose based on total, ideal or adjusted weight. This feature is currently only available for the adult portion of the app.
This functionality would not have been possible without the contribution of our two experts in pharmacy for the obese, authors of the first book published on the subject: “Demystifying Drug Dosing in obese patients”

Definitions
Definitions of obesity :
BMI > 30 kg/m2

Calculation of ideal weight:
We decided to use Robinson's formula, since it is derived from factual and not empirical data (Pai & al. 2000). It gives results very similar to the Devine and Miller equation.

Man : 51.65 + 1.85 x (height in inches - 60)
Woman : 48.67 + 1.65 x (height in inches - 60)

Literature review
For each medication, a literature review was carried out to determine the optimal mode of administration in the obese population. When there was no literature available, we leaned towards the opinion of our experts, based on the pharmacokinetic properties of the different molecules.
