What level of practitioner should people involved in data collection be?
This is a structured interview and chart review, so anyone who has been trained can do it. We find that college-age people and older are best, just because of the dynamics of interaction with parents. Some sites choose to rely on undergraduate research assistants or medical students, while others rely on respiratory therapists and nurses. Still others rely on doctors (e.g., colleagues of the site PI, residents, fellows). It depends largely on the type of staff you have available at your hospital.
