This document discusses a clinical trial called RESTORE that studied sedation methods for pediatric patients on mechanical ventilation. It aimed to follow up with patients 6 months after discharge to assess outcomes. The task described was to locate patients lost to follow up in order to update their contact information for future studies. Methods involved searching online and contacting primary care providers while maintaining privacy standards. Challenges included technical issues, language barriers, unavailable records, and unreachable families. The work resulted in 4 verified updated addresses and identification of 14 potential matches requiring confirmation.
