The healthcare supply chain is the network of organizations and processes that move medical products from raw materials to the patient’s bedside. It connects manufacturers, distributors, purchasing groups, and healthcare providers in a coordinated system that handles everything from surgical gloves to life-saving medications. In the United States alone, medical supply expenses reached $146.9 billion in 2023, making up roughly 10.5% of the average hospital’s operating budget.
How Products Move From Factory to Patient
A medical product’s journey typically follows a consistent path: manufacturer to distributor to provider. Manufacturers are the starting point, producing pharmaceuticals, medical devices, bandages, surgical tools, and diagnostic equipment. Some are massive pharmaceutical companies producing branded or generic drugs, while others are specialized firms building medical technology like imaging systems or implantable devices.
Distributors sit in the middle. These include wholesale suppliers and logistics companies that warehouse products, manage deliveries, and track shipments to keep everything running on schedule. Some healthcare organizations also use third-party logistics providers for specialized needs, such as temperature-sensitive biologics that require cold chain management throughout transit.
Providers are the final stop before the patient. Hospitals, pharmacies, clinics, and assisted living facilities receive the products, manage their own internal inventory, fill prescriptions, and deliver care. Each facility must balance having enough stock on hand to treat patients against the cost of holding excess inventory.
The Role of Group Purchasing Organizations
Over 95% of U.S. hospitals use Group Purchasing Organizations, commonly called GPOs, to buy their medications, devices, and supplies. A GPO pools the buying power of hundreds or thousands of hospitals and negotiates prices with manufacturers on their behalf. The result is lower prices and less administrative work for individual hospitals, which would otherwise need to negotiate thousands of contracts on their own.
GPOs don’t just secure flat discounts. Most operate through percentage-based contracts that give hospitals deeper price cuts for committing to buy a certain share of their products from a preferred brand. For example, a hospital might receive a steeper discount on a medication if it purchases at least 80% of that drug category from the GPO’s contracted supplier. Some GPOs run fully committed models, where member hospitals must buy from a limited list of approved products in exchange for the deepest possible pricing. This selective contracting effectively steers hospitals toward specific brands, which gives the GPO more negotiating leverage with manufacturers but limits the hospital’s flexibility to choose alternatives.
Inventory Strategies: Lean vs. Stocked Up
Hospitals and health systems generally choose between two broad inventory philosophies. The just-in-time (JIT) approach keeps minimal stock on hand, replenishing supplies only as they’re used. It’s a pull-based system that synchronizes orders with actual demand, reducing waste, cutting storage costs, and improving product quality by avoiding items sitting on shelves past their usefulness. JIT works well in stable, predictable environments.
The just-in-case (JIC) approach takes the opposite stance, maintaining safety stock, backup suppliers, and buffer capacity to absorb unexpected disruptions. During the early pandemic years, JIT systems were tested by supply shocks unlike anything the industry had previously experienced, and many hospitals found themselves scrambling for basic protective equipment and medications. Research shows that when supply disruptions are severe, increasing safety stock (a JIC strategy) improves operational performance, but only when hospitals aren’t simultaneously trying to run lean JIT systems. The two approaches can conflict with each other when shocks are large. In calmer times, hospitals with strong JIT practices benefit most from keeping backup inventory low.
Many health systems now aim for a hybrid, maintaining lean day-to-day operations while keeping strategic reserves of critical items like emergency medications and protective equipment.
Why Shortages Happen
Drug and device shortages are a persistent problem, and the causes are rarely simple. On the supply side, manufacturing problems, unavailable raw materials, shipping disruptions, and business decisions (like a manufacturer discontinuing a low-margin product) all play a role. Demand spikes, such as a sudden flu season or a new treatment protocol, can outpace production. Regulatory actions, including plant shutdowns for quality violations, can take a major supplier offline with little warning.
Mitigation strategies work across several levels. In the short term, hospitals develop workarounds for the current shortage, often substituting an alternative drug or rationing existing stock. Longer term, the focus shifts to operational improvements: better communication among stakeholders, formal shortage reporting and tracking systems, and ensuring multiple suppliers for critical raw materials so a single point of failure can’t halt production.
Technology That Tracks It All
Modern healthcare supply chains rely on layers of digital technology to maintain visibility from warehouse to patient. Internet of Things (IoT) devices, which are small connected sensors attached to shipments, can continuously monitor a product’s temperature, pressure, location via GPS, and other conditions during transit. If a shipment of vaccines drifts outside its required temperature range, the system can trigger an alert before the product is compromised.
Radio-frequency identification (RFID) tags and QR codes allow hospitals and distributors to scan and track individual items in real time, improving inventory accuracy and reducing the manual counting that leads to errors. Blockchain technology is increasingly being explored as a way to create tamper-proof records of a product’s journey through the supply chain, which helps verify authenticity and combat counterfeit drugs. Together, these tools provide continuous data flow between manufacturers and end users, enabling faster decision-making and reducing delays, fraud, and damaged goods.
Federal regulations also drive traceability. The FDA requires every medical device to carry a Unique Device Identifier (UDI) on its label, presented in both plain text and a scannable format like a barcode. Reusable devices that are reprocessed between uses must be permanently marked with this identifier directly on the device itself. This system allows any device to be traced back through the supply chain if a safety issue arises.
Environmental Impact of Healthcare Supply Chains
The healthcare supply chain carries a significant carbon footprint. Approximately 87 to 88% of a healthcare supplier’s greenhouse gas emissions fall into what’s called Scope 3, meaning they come not from the company’s own operations but from the broader value chain: raw material extraction, manufacturing by contract partners, shipping, and disposal of products after use.
Health systems are beginning to address this. Kaiser Permanente evaluates all purchases against a set of environmentally preferred principles, assessing the lifecycle impacts of goods and services before buying. Medtronic has cut its organizational emissions by 35% since 2020 and is targeting carbon neutrality in its global operations by 2030, with a net-zero goal across its full supply chain by 2045. Over 130 organizations have signed the U.S. Department of Health and Human Services’ Health Sector Climate Pledge, and the broader industry goal is a 50% emissions reduction by 2030 with zero emissions by 2050. Increasingly, GPOs and health systems are building sustainability metrics into vendor contracts, making environmental performance part of how suppliers are selected and evaluated.
