Keeping Cold Chains on Alert with IoT Analytics

Oct 4, 2023

COVID-19 vaccine shipments have just begun. Is the healthcare industry ready with an infallible cold chain?

With multiple COVID-19 vaccines on the horizon, the next challenge is a cold (supply) chain ready for the onslaught of shipping vaccines across the world. It will not be simple to implement, considering the number of transfer points from manufacturing to administration sites. Vaccines are typically transported by air and then by road (usually trucks), with multiple stops and storage at the distributor before reaching the endpoint, where they once again go into cold storage. The last mile to the healthcare provider could be delivered to a nearby town by any means available.

Almost a fourth of vaccines are degraded by the time they arrive at their destination, due to incorrect shipping procedures. Losses from vaccines exposed to temperatures outside the recommended range are estimated at USD 34.1 billion annually, including product cost and wasted logistics expenses; a number that is likely to increase exponentially if you consider the cost of wasted COVID-19 vaccines.

Cloud platforms, blockchain, and IoT-enabled monitoring sensors provide real-time visibility into temperature changes once the vaccines leave the labs or manufacturing facilities … and the opportunity to check before there is damage.

IoT can transform cold chain management
Cold chains can collapse due to mechanical failures, heavy traffic, human error and even theft. IoT also helps the entire cold chain infrastructure function as a single unit, bringing in new levels of safety and cost-efficiency.

Using GPS-enabled packaging material, or by attaching RFID sensors to the actual shipment, loading device or crates makes it possible to measure the temperature, humidity and other variables affecting the shipment.

IoT devices transmit this data in real-time, sending alerts or notifications to various stakeholders when conditions are compromised. Supported by predictive and descriptive analytics, logistics firms can make any necessary adjustments to maintain the integrity of the vaccines, and even initiate a lockdown in case of theft.

How IoT devices work in the cold chain
IoT sensors can read light, temperature and humidity, in addition to manufacturing details like serial numbers. Armed with this data, vaccine manufacturers can specify rules such as temperature bands and program them into the sensors. The system can send alerts for deviations from the specified temperature range as well as the location of the shipment. Similarly, when a hospital receives the vaccine shipment, it can check the dashboard to view the chain of custody and other details thanks to the data stored in the sensors and accessible via the cloud. So even if the manufacturer missed/ ignored an alert about the vaccine being unusable, the hospital can reject the shipment because the logistics firm messed up.

Another method is to use scannable barcodes. IoT-powered barcodes can upload information to a cloud-based blockchain system. Barcode tags can monitor details like aggregate time outside the specified temperature band, and return a message to the scanner within seconds, confirming the safety of the vaccine or suggesting safety measures.

Unlocking cold chain insights
When equipped with timely and relevant data, pharmacos can optimize inventory and ensure safe vaccine distribution. Data gathered by IoT devices and sensors can be integrated with other external data for deeper insights to automatically trigger action without human intervention. The data gets processed at the edge of the network at the device level or local level. Cloud-based solutions can process tons of data generated by IoT, AI/ML and advanced analytics to deliver diagnostic and predictive insights in real-time for location, condition, consumption and anomaly detection.

Closing thoughts
Fail-safe cold chains are essential to distributing vaccines because any inefficiency could mean losses worth billions of dollars, or losing ground in the fight against a pandemic. In response, companies are now adopting technologies to better monitor cold chain shipments, improve logistics management, and achieve near-perfect visibility into the transportation process. They are now able to introduce the necessary checks and measures early on. Such data insights can also help build stronger networks and more resilient processes. For example, data can reveal underperforming or problematic partners, allowing companies to find better suppliers and service providers to be part of their cold chain.
