Centre for Safe Medication Practice and Research

About Centre for Safe Medication Practice and Research

Medicines play an important role in clinical practice, contributing to the health and longevity of many patients. Yet many challenges prevent their optimal use, resulting in patient harm. Adverse drug events are a source of significant patient harm. There are worldwide initiatives to reduce adverse drug events. Under the strategic plan of the Department of Pharmacology & Pharmacy of The University of Hong Kong, the Centre for Safe Medication Practice and Research (CSMPR) was established in 2012 to foster research and development in medication safety in collaboration with local and international partners.

The mission of the CSMPR is to improve the health and quality of life of patients through interdisciplinary collaborative research that addresses questions central to medication safety. We focus on delivering innovative results that optimise the safe and effective use of medications. Drawing on the combined expertise of specialist resources from the Queen Mary Hospital (QMH), The University of Hong Kong (HKU) and other collaborative partners, the CSMPR provides a world-renowned platform for the training of health care professionals, patients and the general public on the safe and effective use of medications.

Our aim is to deliver high quality research with results relevant and applicable to health in real world settings, thus optimising and promoting the safe and effective use of medicine in Asia and beyond.
