I PREPARE: development and clinical utility of an environmental exposure history mnemonic.

The I PREPARE environmental exposure history mnemonic is a quick reference tool created for primary care providers. Health care providers (N = 159) were asked to evaluate a prototype mnemonic, to suggest new health history questions, and to propose the deletion of less relevant questions. The goal of this evaluation was to create a practical and clinically relevant mnemonic, rather than to obtain quantitative estimates of validity. The final I PREPARE mnemonic cues the provider to "Investigate potential exposures;" ask questions related to "Present work," "Residence," "Environmental concerns," "Past work," and "Activities;" provide "Referrals and resources;" and "Educate" the patient by reviewing a checklist of strategies to prevent or minimize exposures. The sequence of I PREPARE makes intuitive sense by cueing the provider to ask specific questions and provide educational materials to the patient. National improvements in the quality of environmental exposure history data are predicated in part on the creation of simple and convenient tools for use in clinical practice.
