Participant allocation

Health professionals will be randomly assigned to one of three intervention groups based on a sequence of computer-generated random numbers using a blocking factor (randomly varying between 6 and 9). A research coordinator will contact potential participants and will confirm their eligibility after they register for the study via email. Once participants have been deemed eligible and have provided consent, they will be randomly allocated to one of the three intervention groups using the central randomization scheme by a data manager at the research study Methods Center. The data manager will document the participants’ initials (first and last) as well as their date of birth (month and year) before running the randomization program. To ensure concealment of allocation, the data manager will document the intervention assignment and assign a study identification (ID) number after running the randomization program. This information will then be provided to a research assistant not involved in data collection. Participants will then be informed by email as to their group assignment following randomization.
