"I'm Just Guessing These Answers!" An Evaluation of the (In)Accuracy of Patient-Reported Medical History Collected as Part of a Breast Imaging Program.

INTRODUCTION:Hundreds of thousands of Ontario women receive breast screening imaging each year. The patient's medical history is a vital tool used to personalize breast screening approaches. This study evaluated the accuracy of self-reported medical and imaging history in patients about to receive breast imaging procedures in a large urban Canadian hospital. The patient experience with using a blank screening form vs. a novel prefilled screening form was also evaluated. METHODS AND MATERIALS:The study was conducted in two phases. Phase 1 compared patient-reported information (via the blank screening form) to information previously captured in the Radiology Information and Picture Archiving Communication Systems to assess data accuracy. In phase 2, study questionnaires were used to collect data on the patients' experience with the screening form in two cohorts (between the blank and a novel prefilled screening form). RESULTS:Data accuracy: for mammography (n = 60), 40% of the patients could accurately recall when and where their last mammogram was performed. For breast ultrasound (n = 43) and breast magnetic resonance imaging (n = 20), significantly fewer patients could accurately recall the date their last test was performed (14% and 10%, respectively). Of those who had previous breast surgery (n = 18), 100% were able to recall whether the surgery resulted in a benign or malignant diagnosis, and 61% were able to accurately recall the year they had the breast surgery. PATIENT EXPERIENCE:Of the returned questionnaires, 65 provided feedback on the blank screening form while 55 provided feedback on the prefilled form. Ninety percent preferred to fill out the new prefilled screening form. The themes acknowledged a general improvement in the screening form, a decrease in frustration associated with having to recall their medical history, and the patients felt that the institution better understood their medical history. CONCLUSIONS:The findings of this research indicate that asking patients to complete a blank medical screening form is a highly inaccurate method of gathering that important information. When that information was prefilled for the patient to review and update, patient frustration and stress were decreased, while satisfaction and confidence in the organization were increased.
