Objective: to evaluate the effectiveness of an educational workshop versus standard information in improving knowledge and perceived self-efficacy in basic life support.
Study Design: randomized crossover clinical trial with two intervention periods and a one-month washout.
Methods:
* Participants: Parents, caregivers, or legal guardians of infants under 6 months of age attending well-child check-ups at three primary care centers in Cantabria.
* Interventions: Participants will be randomly assigned to two sequences: group AB will first receive intervention A (an explained information leaflet) followed by intervention B (a theoretical-practical workshop); group BA will follow the reverse order.
* Randomization: Allocation sequence concealed using sequentially numbered, opaque sealed envelopes.
* Blinding: Outcome assessors were blinded to group allocation; participants and those delivering the interventions were not.
* Implications for practice: Planned implementation of practical workshops in childcare to enhance family responses to life-threatening pediatric emergencies.
