Over a period of several months, you notice a significant increase in the number of pediatric patients (less than 1 year of age) who present to the emergency department (ED) with traumatic injuries. You are concerned because many of these injuries could have been prevented and some of them appear nonaccidental. You decide to design an intervention to address risk factors for trauma in infants. There are many settings in which such an intervention can be implemented: the newborn nursery, outpatient clinics, and EDs. The target audience can be expectant parents, parents, healthcare providers, or any combination thereof.
• Where might you find data on traumatic injuries in your area? How can you use these data to help you design an intervention? • Design an educational intervention to address the risk factors for traumatic injuries in infants. Decide on a site and a target audience. Identify an outcome. • What type of study design might you use for your proposed intervention? • What are the advantages and disadvantages of the design you have selected? • What variables could be considered confounders? • Describe some of the systematic errors that could occur in your study, and why.
