Residency Staff

Paul T. Nowierski, BS Pharmacy
Program Director

Paul T. Nowierski takes pride in leading Lenox Hill Hospital’s department of pharmacy with Clinical Pharmacists - Advanced Practice, a program that focuses on neonatal/pediatric services, intensive care services for medicine, surgery and cardiac care, as well as emergency and anticoagulation services.

Our pharmacy residency program has forged a solid relationship with Arnold & Marie Schwartz College of Pharmacy and Health Sciences at Long Island University (LIU), which contributes on-site LIU faculty along with more than 50 student rotations yearly -- of which Paul precepts 30. This includes rotations in IV admixture, information technology, medication safety and hospital pharmacy administration.

Over the last 10 years, Mr. Nowierski has been able to redesign the physical pharmacy, IV clean room, admixture services and workflow/distribution. He also doubled the staffing to help deliver improved patient care on a daily basis. Many of the improvements were technological advances, which included the configuration of Sunrise Clinical Manager for CPOE (2005) and Sunrise Medication Manager for PIS (2009). This embedded safeguards, smart alerts and clinically correct order sentences in the system to enhance the physicians’ order entry, reducing common sense medication errors by 50 percent. He also introduced Omnicell Automated Technology (2004) in all areas from operating rooms to nursing units to change the medication distribution process, increasing medication safety and reducing turnaround for nurses/physicians to bring medications closer to the point of care. 

“These past 10 years have taught us that we can always improve on the work we have done,” said Mr. Nowierski. “We can always enhance technology to bring us to a new level, and we need to continually believe that it is our staff that ultimately defines the character of our pharmacy services. We therefore must continue to invest in our people, improving their skills, to enhance the patient outcome and our contribution to the healthcare team.”
