The Department of Pharmacy at Westchester Medical Center consists of a main inpatient pharmacy, which operates 24 hours a day, seven days a week, multiple pharmacy satellites, including pediatrics, oncology, outpatient infusion center, and outpatient community and specialty pharmacy. The hospital and the Department of Pharmacy utilize electronic health records (EHR) to maintain medication profiles for all patients. Unit dose medications are dispensed utilizing automated dispensing cabinets (Pyxis). The Pharmacy prepares and dispenses all medications that are required to be prepared in an aseptic environment and utilizes state of the art compounding facilities to compound ready-to-administer non-hazardous admixtures. The Pharmacy coordinates the review of all adverse drug events or medication occurrences by the Pharmacy and Therapeutics Committee. These include reporting of adverse drug reactions (ADRs) and medication errors that occur in the medical center. All reports are reviewed and analyzed by the Medication-Use Safety Subcommittee (MUSS) to determine trends and make recommendations in minimizing the incidence of adverse events or medication incidents. The Pharmacy is responsible for all aspects of investigational drug use, which include maintenance of all research protocols, provision of information, safe storage, record keeping, dispensation of investigational products, patient education and monitoring of therapy, and return or disposal of unused investigational products. The Department of Pharmacy utilizes the expertise and skills of Clinical Pharmacy Specialists in the areas of Ambulatory Care, Critical Care, Emergency Medicine, Hematology/Oncology/Stem Cell Transplantation, Infectious Diseases, Internal Medicine, Pain Management, Pediatrics/Neonatology, and Solid Organ Transplant.
