The Clinical Overnight rotation is a required 2 week long learning experience at Mercy Hospital of Buffalo (MHB). This rotation is similar to the EDI and EDII rotations, but gives the resident experience during the overnight hours (2100 – 0700) which can be unpredictable. Responsibilities on this rotation will expand to provide clinical coverage for the entire hospital during the overnight hours. This will include attendance of all rapid responses, cardiac arrests, strokes, reviewing critical care patients, and answering drug information questions from any hospital provider. During this rotation, the pharmacy resident will work collaboratively with several disciplines including the ED physicians, ED mid-level providers, hospitalists, intensivists, critical care mid-level providers, medical residents and ED nurses to optimize pharmaceutical care for the ED patients. The resident will use evidence-based medicine to provide pharmaceutical care to a range of hospitalized patients, from the ambulatory to the critically ill.
