Sustainable Supply Chains

Addressing accessibility challenges in low- and middle-income countries by strengthening health supply chains.


Across the globe, two billion people do not have access to medicines. At least half of the world’s population lacks access to essential health services and 100 million people are pushed to poverty due to health expenses. Low- and middle-income countries are the most affected, requiring major interventions to overcome health access barriers.

Access to care for patients in low- and middle-income countries with developing health systems is particularly challenging, especially for those at the base of the global economic pyramid. Establishing a robust supply chain is critical to ensure safe, effective, and continuous health-care-delivery.

We work collaboratively with our international and local partners to improve access to medicines globally. I am particularly proud that our in-house expertise is contributing to address the challenges in supply chain in low- and middle-income countries so as to ensure that high-quality medicines sustainably reach patients in need.

Our engagement

In our Company, we work to achieve progress for mankind and to contribute to health for all.  
We are committed to address supply chain barriers, from the first mile supply challenges associated with manufacturing, storage and distribution of the medicines, to the last mile difficulties to deliver high quality medicines to patients in remote locations.  

We engage in capacity building activities by working with international and local partners for training throughout and across the supply chain. Through our supply chain work, we strengthen and optimize the delivery of medicines to patients.

Our approach to sustainable supply chains is based on cross-cutting principles: to ensure quality and safety of our medicines during production and delivery, to integrate process steps for improving efficiency and time delivery, to implement measures including trainings to local partners on best practices.  

Our Activities

We believe that innovation and partnerships are important elements to tackle current supply chain challenges.

In low- and middle-income countries, we prioritize our efforts by implementing capacity building initiatives that address the critical challenge of ensuring product reach for patients.  We engage non-profit organizations and local distributors to improve order fulfillment, rate for quality material, turnaround time.

Our Global Health unit, together with Global Healthcare Operations, drives these collaborative efforts in line with its mission to improve access to health for the underserved populations in low- and middle-income countries.


Created as a volunteer pool of supply chain experts from our company, the Access Mentorship Program structures and organizes sharing of knowledge and experience with local supply chain experts in Africa. Virtual trainings and projects tackle various domains of expertise, including demand and supply planning, inventory management, purchasing practices, warehouse and storage management, bar coding, quality control and standards, customer service and importation processes.

We collaborate with Business for Health Solutions (BHS), a non-profit organization whose mission is to increase healthcare access for communities in Africa by building the capacity of local healthcare enterprises. BHS connects teams of volunteer experts from us to distributors and healthcare service providers and facilitates remote technical assistance projects to help address their supply and logistics challenges. The program was piloted in Tanzania and achieved some tangible successes in several key performance indicators. With the support of Merck KGaA, Darmstadt, Germany, it is expanding to other low- and middle-income countries, including Ghana.
