Minimal patient identification information will be collected. The patient account number and telephone number must be collected. Subjects will also be assigned a study number for data analysis; account numbers will not be included in the data analysis. Personal health information will be available only to the study investigators. All collected data will be stored in a locked filing cabinet in the Emergency Department until it can be delivered to CAMC Outcomes Research. Electronic data will be stored on a password protected computer. At the conclusion of the study, all data collection sheets will be shredded and electronic data destroyed.
