1. All patients aged 50 years and older will be approached by the scribe after the chief complaint is ascertained. The scribe will begin and administer a questionnaire on all age eligible patients. Having already taken a history, the scribe will be able to easily determine if the patient is eligible for the study (i.e. does not meet any of the exclusion criteria). If the patient is eligible, the scribe will read the questionnaire to the patient.
