Vaccine storage practices in primary care physician offices: assessment and intervention.

Purpose: To assess the proportion of primary care physician (PCP) offices meeting vaccine storage guidelines, identify factors associated with low compliance, and evaluate whether a quality improvement (QI) activity improves compliance.

Methods: We examined compliance with guidelines of 721 PCP offices contracted with a national managed care organization in four cities. A QI activity (educational materials, written feedback, and distribution of thermometers) was conducted at baseline and a follow-up assessment occurred within 3 months.
