This Year’s Flu Exposes a Flaw in Our Medical System

A just-in-time system can be disrupted by an unexpected surge in demand or a delay in delivery

Published: Thursday, February 15, 2018 - 12:01

Flu season in the United States typically peaks in February, but this year’s outbreak is already one of the worst on record. As of Jan. 6, 2018, 20 children have died from the flu, and overall mortality caused by the virus is already double that of last year’s.

One reason the flu is so severe this season is that the dominant strain is H3N2, which has an impressive ability to mutate and is particularly aggressive against Americans over 50.

Making the threat worse is the fact that most of the IV saline bags used in common medical treatments and procedures—including severe cases of the flu—are made in Puerto Rico, which is still reeling from Hurricane Maria. Hospitals in some areas around the country that are operating at or above capacity because of the flu are quickly running low on saline, causing them to resort to time-consuming and potentially dangerous treatments of patients.

The IV saline shortage is unlikely to cause a life-threatening breakdown of medical treatments. But the shortage does expose a dangerous flaw in the medical supply chains that everyone relies on to counter disease outbreaks or bioterrorism. Many different types of important medical equipment and medicines either come from abroad or rely on a single producer.

Global supply chains

Globalization has changed the way we produce, transport, and store almost anything, including medicines and medical supplies. Now that it’s inexpensive to transport goods, many can be easily produced abroad at substantially lower costs. In nearly all cases, that benefits producers and consumers alike.

For the medical industry, approximately 80 percent of all pharmaceuticals used by Americans are produced overseas. The majority of this production takes place in China and India.

Forty-three percent of saline in the United States comes from Puerto Rico. The United States was already running below optimal levels of saline when Hurricane Maria hit.

Rapid transportation of goods also allows most industries to rely on “just in time” deliveries. That means goods arrive only shortly before they are needed, rather than arriving in large shipments.

In most situations, and for most goods, that causes few issues. However, when there’s an insufficient stockpile, delivery delays can be life-threatening. Many of our hospitals receive shipments of critical pharmaceuticals three times a day.

Unhappy coincidences

As researchers studying how countries can prepare for disease and disasters, it’s clear to us that the IV saline shortage is just the tip of a gigantic iceberg.

There are two ways the “just in time” system can be disrupted: an unexpected surge in demand or a delay in delivery. In this case, both occurred simultaneously. The United States is dealing with an unusually potent strain of the flu, while Hurricane Maria brought saline production in Puerto Rico to a grinding halt. If only one of the two had occurred, it’s unlikely the United States would have experienced a shortage.

Now, hospitals overrun with flu patients have to turn to alternatives to IV saline. One is an IV push procedure, in which medications are manually “pushed” into the IV line. This can be deadly if not done correctly.

In the case of IV saline, the simultaneous occurrence of both demand and delay was accidental. Unfortunately, it’s not only possible that such confluence will occur in the future, it’s likely. In the case of pandemics or biological warfare, there will likely be both a surge in demand for important goods and a simultaneous disruption of production and delivery.

If a pandemic disease severely affected China or India, where large shares of medicines come from, production could be knocked out or slowed. That would leave the rest of the world vulnerable to the disease’s spread, because there would be no supply of crucial medicines to combat it. The 1918 influenza pandemic caused disruptions that prevented coal from being delivered to the northeastern United States. That left some without heat in the height of winter, causing people to freeze to death and compounding the deadly pandemic.

Today, such a breakdown could leave hospitals and other crucial infrastructure without electricity. If the spread of the disease is intentional, as in cases of bioterrorism or bio-warfare, adversaries could target global supplies of crucial treatments.

Preparing for problems

The destruction in Puerto Rico and the impact it has had on the supply of small IV saline bags in U.S. hospitals is a warning. This time, it’s IV saline. Next time, it might be electricity to run intensive care units, or critical antibiotics to treat infections.

Global supply chains are a massive puzzle, but public health and emergency preparedness officials need to, at a minimum, understand every link in the chain of critical goods. Without a thorough understanding of the supply chain, it’s difficult to preempt problems that could arise in times of emergency. Hospitals and other crucial infrastructure, such as power plants and the transportation industry, may want to diversify their suppliers of critical goods and encourage those suppliers to not focus production in a single area, especially not to an area prone to natural disaster. A final, but far more costly, option is to ensure we can produce most of these goods domestically in times of emergency.

In our view, the solution depends on a partnership between government and industry. Federal, state, and local governments have to alter procedures, but private companies involved in the production and delivery of critical goods have to plan ahead for emergencies.

The ConversationIf these weaknesses in our global supply chains are not addressed, especially as they relate to medical supplies, pharmaceuticals, and other critical goods, we are headed for disaster.

A just in time system can be distrupted by an unexpected surge

Mr. Morten Wendelbo and Christine Crudo Blackburn provided a great explanation of this ciritcal flaw within our medial system. this condition ("unexptected surge in demand or a delay in deliver")also occurs in many other industries significantly affecting just-in-time supply strategies implemented across all sectors of industires.  The impact of the gobalization of supply chains, are far reaching (all "interested parties") and have the potential to create crippling consquences that we are unprepared to quickly resolve. the authors also discuss impact of bioterrorism or biowarfe adversaries targeting our global supplies of critial product needed for treatment, but this threat could also come from dark web hackers targeting the information that controls our production, transproation and storage processes.  The authors recommended solution makes very good sense, but will take much effort, committment and cooperation from all parties involed including foriegn govenments.
