Pharmaceutical Supply Chains

Research mode

Sustainable development and improvements in global health are key to long term economic growth in the world. Despite increased availability of financial resources and development of new health technologies, many health indicators such as vaccination, infant mortality and life expectancy rates have shown only modest improvements in developing countries. The lack of effective and efficient supply chains for delivering health products to underserved populations in developing countries is one of the reasons for the slow improvement in health outcomes.

My broad area of research in this field focuses on creating new knowledge around how more effective and efficient supply chains for health commodities can contribute towards improved global health.

Supply chains for pharmaceuticals and health products around the world are unique because of the need for stricter quality regulation; decoupling of payers from purchasers; and larger public sector involvement due to the positive benefit externalities associated with the use of pharmaceuticals and health products. Poor affordability due to lack of health insurance, weak regulatory capacity, low population awareness, and weak logistics capacity together result in these unique attributes of healthcare supply chains being further amplified in the developing world.

Research on supply chain structure and comparative study of developing and developed country healthcare supply chains can help in developing trajectories for supply chain improvement.  I endeavor to tackle some of these issues by capitalizing on the knowledge from the academic disciplines of operations management, supply chain management, economics and public health. I use a combination of analytical models, randomized or quasi-randomized field experiments, empirical analysis and case studies to draw inferences about the best pathways to healthcare supply chain improvement.

I feel it is also important to differentiate between supply chains for medical relief organizations and the development of market or public private partnerships driven approaches to the better provision of drugs in low income countries. Medical relief organizations and NGOs are driven primarily by a humanitarian impulse: that failed governments cannot meet the health needs of vulnerable populations and therefore there is an obligation to respond to those needs urgently. Clearly, there is a need for medical relief as it meets immediate health care needs of the population and builds pressure on the governments to design better systems for it poorest segments. However, the long term development of the pharmaceutical supply chains in low income countries in order to make them effective and efficient like the supply chains in developed countries requires a slightly different approach. It requires changes in government policy; the creation of optimal market structures; enhancement of regulatory capacity, and in some instance international donor support to address short term market failures or cover costs of large externalities.  I work with market or quasi-market mechanisms to improve the sustainability, effectiveness and efficiency of pharmaceutical supply chains in developing countries.
