Kathryn Angel has been hired as assistant director for ambulatory care at Harvard’s University Health Services. By implementing a triage system, she wanted to reorganize the Walk-In Clinic.
The staff of the clinic includes 22 physicians, 2 registered nurses and 11 nurse practitioners.

Nurse practitioner: eight-hour shifts, 45% of their ours are available to treat patients in the Walk-In Clinic
