Hospitals source their supplies through a layered network of group purchasing organizations, wholesale distributors, and direct manufacturer relationships. Supplies typically account for about 15% of a hospital’s total operating budget, though that figure climbs to 30% or even 40% in surgery-heavy facilities. The system behind getting everything from surgical gloves to MRI machines into a hospital is more complex than most people realize.
Group Purchasing Organizations Do the Heavy Lifting
Over 95% of U.S. hospitals use group purchasing organizations, known as GPOs, to buy medications, devices, and everyday supplies. GPOs work by pooling the buying power of hundreds or thousands of hospitals, then negotiating bulk contracts with manufacturers and distributors. The result is lower prices and less administrative work for individual hospitals, which don’t have to negotiate every contract on their own.
The two largest GPOs in the U.S. are HealthTrust and Vizient. Research from Weill Cornell Medicine found that hospitals affiliated with these two organizations adopted lower-cost alternatives to brand-name drugs faster than hospitals using smaller GPOs, largely because HealthTrust and Vizient used more aggressive contracting strategies. This illustrates something important: the GPO a hospital belongs to doesn’t just affect price, it shapes which products end up on the shelves.
A typical arrangement works like this. The GPO negotiates a contract with a supplier for, say, IV catheters at a set price. Member hospitals can then order those catheters through the contract. Hospitals aren’t locked in to using only GPO contracts, but most routine purchases flow through them because the pricing is hard to beat independently.
Distributors Move Products to the Door
Even after a GPO negotiates pricing, the physical products still need to get from factories to hospital loading docks. That’s where medical distributors come in. Companies like McKesson, Cardinal Health, and Owens & Minor operate massive warehousing and logistics networks specifically designed to serve healthcare facilities. They stock thousands of products and deliver them on tight schedules, sometimes daily for high-volume hospitals.
For pharmaceuticals, the distribution chain is particularly streamlined. Hospital pharmacies place orders through wholesalers who maintain regional warehouses stocked with medications. These wholesalers handle the cold-chain logistics for temperature-sensitive drugs, manage controlled substance tracking, and ensure hospitals can get urgently needed medications within hours rather than days. Most hospitals rely on a primary wholesaler for the bulk of their drug purchases, with secondary accounts as backup.
Big-Ticket Equipment Comes Straight From Manufacturers
Not everything goes through a GPO or distributor. High-value equipment like MRI machines, CT scanners, and surgical robots typically involves a direct relationship between the hospital and the manufacturer. These purchases require site assessments, installation planning, staff training, and ongoing service contracts that don’t fit neatly into a standard distribution model.
Surgical implants and specialty devices often enter the hospital through a different path entirely. A surgeon may work with a specific manufacturer’s representative who brings devices directly into the operating room. In some cases, hospital management only learns about a new device when the invoice arrives. This physician-preference dynamic creates a parallel supply channel that operates somewhat independently from the central purchasing department, and it’s one of the more expensive and difficult-to-control parts of the supply chain.
Non-Clinical Supplies: Food, Linens, and Cleaning
Hospitals also need enormous quantities of non-medical supplies. Linens, food, cleaning chemicals, and office supplies all require their own procurement systems. Many hospitals outsource these services entirely. A single mid-size hospital can generate over 3 million pounds of laundry per year, as the University of New Mexico Hospitals documented in a procurement contract covering its 629-bed facility and 33 offsite locations. That contract covered soiled linen pickup, laundering, clean delivery, and even storage of overflow and pandemic linen reserves.
These non-clinical contracts are typically awarded through a competitive bidding process. Hospitals issue formal requests for proposals, evaluate vendors on price, quality, regulatory compliance, and capacity, then lock in multi-year agreements. Food service follows a similar model, with many hospitals contracting companies that manage the entire kitchen operation, from sourcing ingredients to serving patients.
How Hospitals Track What They Have
Managing the flow of thousands of different products requires serious technology. Barcode scanning has been the standard for years, but hospitals are increasingly adopting radio frequency identification (RFID) systems for more precise tracking. RFID tags can be read wirelessly in bulk, which is a major upgrade over scanning items one at a time.
Texas Children’s Hospital in Houston, for example, uses RFID to track 784 high-value medications that cost $100 or more per unit. The system confirms that the right drug is going to the right location and that each tagged item is functioning in the system before it reaches its destination. What used to be a 12-step manual process with significant error potential became a two-step automated workflow. UF Health Shands in Florida has used a similar RFID approach for three years to manage crash cart trays in its pharmacy.
RFID also speeds up expiration tracking and drug recalls. Instead of staff manually checking dates and lot numbers on hundreds of items, the system flags products that need to be restocked or pulled, saving hours of work that used to be done by hand.
On the regulatory side, the FDA requires manufacturers to label most medical devices with a unique device identifier (UDI) that follows the product from manufacturing through distribution to patient use. Hospitals use these identifiers to track implants and devices through their systems, which improves recall response times and helps with post-market safety monitoring.
What the Pandemic Changed
COVID-19 exposed how fragile the hospital supply chain could be. When global demand for personal protective equipment surged simultaneously, the normal distribution channels couldn’t keep up. The response reshaped how many hospitals think about sourcing.
Some private hospital groups bypassed their usual regional distributors entirely, purchasing PPE directly from manufacturers in Asia. One European hospital group even sent procurement staff overseas to inspect products and negotiate in person. Public hospital systems, which often have smaller procurement teams, struggled to make similar moves because they lacked the workforce and expertise for direct international sourcing.
The broader lesson has pushed hospitals toward multi-sourcing strategies, maintaining relationships with several suppliers for critical items rather than depending on a single source. Building this redundancy costs more during normal times, but it provides a buffer when supply chains break down.
Emergency Stockpiles as a Last Resort
When a crisis overwhelms both commercial supply chains and a hospital’s own reserves, the federal government maintains the Strategic National Stockpile. Managed by the Department of Health and Human Services, this stockpile exists as a safety net for situations where state and local resources are exhausted or critical medical products simply aren’t available on the commercial market. State health departments coordinate requests to access these reserves, typically during declared public health emergencies. It’s not a routine supply source but rather a backstop for worst-case scenarios.
