Bio statement

I am an attending physician in the Division of Hematology-Oncology at Penn. My research focuses on evaluating and improving access to cancer medicines and treatment outcomes in breast cancer patients in sub-Saharan Africa, and assessing the impact of access to essential medicines for cancer treatment in low- and middle-income countries, on clinical outcomes among cancer patients. I have also worked on the WHO Steering Committee/ Union for International Cancer Control Task Team for updating the Model List of Essential Medicines for Cancer and the Steering Committee for the Medicine Patent Policy: “Feasibility of expanding the Medicines Patent Pool’s scope to include all patented essential medicines.”

This pilot study explored leveraged an implementation science approach to develop and examine the acceptability and usability of culturally appropriate survivor narrative videos for breast cancer treatment in Botswana. The results of the pilot study show that culturally appropriate survivor video narratives have high acceptability and usability among patients with breast cancer in Botswana. In future studies we ill test the implementation and effectiveness of narrative videos on a wider scale as part of a bundled intervention for breast cancer patients undergoing treatment.

This study which was funded by an NIH K01 award from the Fogarty International Center, looked at factors associated with fidelity to guideline concordant breast cancer care in Botswana. In the published results from our qualitative analysis we identified stigma and other multilevel modifiable patient and health system factors associated with fidelity. The results of this study provide supporting data for tailoring future interventions to address these barriers.
