Professor Ravi Anupindi Provides Key Insights on Federal Study Investigating Infant Formula Shortages

Newswise — In a new study overseen by the National Academies of Sciences, Engineering, and Medicine, an international group of experts investigated vulnerabilities exposed by the 2022 infant formula shortage to develop recommendations for a resilient infant formula industry. Ravi Anupindi, Colonel William G. and Ann C. Svetlich Professor of Operations Research and Management and professor of technology and operations, served as vice chair of the study.

Despite complex regulations for infant formula, contamination in production and supply chain issues at Abbott, a leading producer, created a dangerous shortage in 2022. The nationwide shortage affected families across the country, particularly low-income households.

In response to the 2022 shortage, Congress directed the FDA to enter an agreement with NASEM to study the challenges in supply, market competition, and regulation of infant formula in the United States. NASEM assembled a team of interdisciplinary experts for this study.  

The team of researchers recently published their findings and recommendations. In the paper, they identify a number of vulnerabilities exposed by the 2022 shortage and make recommendations to improve the resiliency of the infant formula sector in the United States. As vice-chair of the study, Anupindi provided key insights on the vulnerabilities that impact the infant formula sector and recommendations to industry and policymakers for improving resiliency. Anupindi shared his expertise on the project in the following Q&A. 

The study was a coalition of researchers in several fields. How did an interdisciplinary approach help uncover the challenges of infant formula shortages?

The research entailed understanding the infant formula sector from multiple angles – products and their intended uses; nutritional needs of infants; customer segments and their characteristics; understanding of the Woman-Infant-Child program; end-to-end supply chain including raw materials and components, production, distribution, and retail; roles of government agencies like the FDA, USDA and the U.S. Department of Health and Human Services; regulatory and contracting processes; and crisis management.

Having a diverse team of experts in these areas allowed the committee and myself to develop a holistic understanding of the sector and its vulnerabilities.

How did your previous research on essential medical supply chains and operations influence this project? Were there any previous studies in which you discovered similar systemic challenges? 

I have studied supply chain risk and resiliency issues for over 15 years across different industry sectors. I have previously written case studies on Cisco and Boeing on this topic. I have also been a member of the Supply Risk Leadership Council for 15+ years. In the last few years, I had worked and written on risk, resiliency, and crisis management issues; these include COVID-19 testing scale-up in Michigan, policies to secure health commodities at the national level, written testimony to U.S. Senate Committee on Homeland Security & Government Affairs and a NASEM study on a Globally Resilient Supply Chain for  Pandemic Influenza Vaccine. 

The core insights from these experiences were relevant to the infant formula sector as well, though there were some unique aspects of the infant formula market and distribution channels.

The report notes persisting gaps in the infant formula system. What are the most critical gaps?

In our report, we use a vulnerability framework to identify gaps in the infant formula system. These included: 

1. Lack of a robust risk and resiliency management system at a company and sector level
2. Concentration of production
3. Lack of information and authorities to ensure speedy recovery post-disruption
4. Inadequate communication, lack of coordination, and unique structure of WIC impeded better management of adverse effects on consumers
5. Structural barriers to the protection, promotion, and support of breastfeeding

The extent of the infant formula shortage and its impact will depend on the nature and scale of the disruption.

What actions can business leaders and policymakers take to reduce the risk of future disruptions in the infant formula supply chain? 

Our report has made several specific recommendations for business leaders and policymakers to address each of the vulnerabilities identified in the study. A few of these include: 

1. The development of robust risk and resiliency management plans by each company
2. The FDA to ensure that manufacturers have such plans and that, collectively, these plans ensure sector-wide resiliency
3. The USDA to ensure that companies supplying WIC programs have robust risk and resiliency management plans
4. Congress to enact rules and laws to ensure better information visibility and faster recovery and if needed offer incentives to industry to develop resiliency. The FDA will also need support to develop its capabilities in supply chain risk and resiliency management of the sector

We have recently seen several other shortages and disruptions in the medical and pharmaceutical industries, e.g., certain prescription drugs or the CDC's recent warnings on shortages of BACTEC Blood Culture bottles. How similar or different are these challenges to the infant formula shortages?

At a conceptual level, issues are similar. Preparedness and response strategies will, however, differ based on the product category, customer segments, structure and governance of the supply chain, and channels of distribution. Many of the medical and pharmaceutical supply chains are global, adding to opaqueness and risk exposure. In contrast, the infant formula industry is dominantly domestic but concentrated, so the nature of risks differ. In addition, because WIC plays such a dominant role in infant formula distribution and sales in the United States, managing this effectively is a unique issue for this industry to ensure access to more vulnerable populations.

Has participating in this study influenced your future research? Do you have any upcoming projects?

The entire project was fast-tracked and just about a year long. We did not have enough time to research some of the issues deeply. We have called some of these areas out as needing more research. Immersing myself in this project, I learned a lot about a new critical industry from my fellow expert committee members. I am walking away with several research project ideas. At Michigan Ross, we have just started one research project to quantify vulnerable populations' barriers to accessing infant formula.
