Dr. Bayer was very thorough and understanding of my symptoms. She was easily able to see that I most likely had strep throat and she quickly ordered the swab to confirm diagnosis. As soon as the results came back (about 15-20 minutes), Dr. Bayer called me directly to let me know and put my prescription order in. It was a great experience and I felt 100% within 48 hours of starting antibiotics.

Disclosures

Katherine Bayer, MD reported no external professional relationships for calendar year 2024.

External Professional Relationships

Pharmaceutical, device, and biotechnology companies frequently collaborate with basic scientists and physicians within an academic medical center to help advance science and improve patient care. These relationships are important in achieving scientific breakthroughs and in establishing the effectiveness and safety of promising new therapies. In order to assure objectivity in clinical research and patient care, the Northwestern University Feinberg School of Medicine (Feinberg), Northwestern Memorial HealthCare, Children's Hospital of Chicago Medical Center, and the Shirley Ryan AbilityLab have adopted integrity policies that require research and clinical faculty (in full-time, part-time, and unpaid/voluntary categories) to report compensated and uncompensated external industry relationships. Patients are encouraged to discuss these disclosures with their physician as well as to inquire as to how these relationships are overseen by Feinberg.
