Promoting breast health awareness: Can a sensor-enabled training system for patient education help?

INTRODUCTION

According to a 2009 study published in the Journal of Clinical Oncology, 79% of women (N = 222) diagnosed with breast cancer reported that they identified their cancers through breast self-exam (BSE). However, the U.S. Preventative Services Task Force does not require clinicians to teach women how to perform BSE.

METHODS

To address this grave challenge, our team at the Technology Enabled Clinical Improvement (TECI) Center has developed a mobile, sensor-enabled haptic training system to teach women proper BSE technique. To validate the efficacy of the training system, our team deployed a data collection at the 2019 Breast Cancer and African Americans (BCAA) event where survey, sensor, and anecdotal data were collected from 61 participants. The custom-built breast model used in this study had a single, hard mass embedded in it.

RESULTS

Participants at the BCAA event were able to successfully identify the mass 65% of the time and used an average force of 7.2 N. When looking at participants' confidence in their abilities to perform BSE, only 10% of respondents answered "very confident" pre-training whereas post-training, the reporting for "very confident" jumped to 66% (p < 0.01).

CONCLUSION

By comparison, our previous work revealed that practitioners who use less than 10 N of force are 70% more likely to miss a lesion. The integration of sensors into the BSE haptic training system allowed for objective, evidence-based assessment of hands-on skill. In addition to teaching women proper BSE technique, this training empowered women to be informed advocates in their breast health journey. Future community-based training/feedback sessions will allow for continuous advancement of the training system.
