Hospitals handle inventory differently from stores or factories. They must keep important medical supplies ready, not just think about cost. These supplies can save lives, so hospitals often keep more stock than other industries. This leads to extra supplies that might expire or become useless.
Hospitals face two main problems with their supplies:
Balancing enough supply without having too much is hard and costly. Finding ways to manage this balance is very important.
Horizontal arrangements happen when hospitals work together as equals, often in groups called multi-hospital systems. These groups let hospitals share supplies and manage risks better. This is especially helpful where delivery or transportation is weak.
More than half of U.S. hospitals belong to these groups, showing how common this setup is.
Research on hospitals in California shows that being part of a system can lower inventory costs. Hospitals in a group can buy supplies together and manage stock more efficiently. This helps hospital managers feel more secure and avoid keeping too many extra supplies.
Local hospital systems have the biggest effect because nearby hospitals can quickly share resources. When transport or delivery is slow or unreliable, working closely with nearby hospitals is very important for keeping supplies steady.
Hospitals face higher risks because it is hard to predict how much medical supplies they will need, and transportation may be weak. Multi-hospital groups help by sharing these risks. If one hospital runs low, others can provide supplies faster.
This sharing also reduces pressure on hospital managers. It lowers the chance of running out of supplies or wasting excess stock, which saves money.
How well multi-hospital systems work depends on local conditions. Poor transportation, bad delivery services, or hard-to-reach locations make hospitals keep more supplies. In these cases, working together helps hospitals manage pooled supplies and order together.
Demand changes too. Illness outbreaks or emergencies can change how many supplies a hospital needs suddenly. Multi-hospital groups help balance these changes by moving supplies where they are needed, reducing extra stock.
Studies show hospitals not in groups often keep bigger stockpiles to cover for uncertainty. This leads to higher costs and more wasted supplies.
Hospitals also use other methods to lower risks and costs, such as:
For example, prices for certain medical devices fell because of better buying plans and set rules. Bare-metal stent prices dropped from about $1,000 to just over $600 between 2006 and 2014.
The COVID-19 pandemic showed how fragile hospital supply chains can be. Many supplies ran out quickly. Just-in-time inventory systems, which normally save money by keeping little stock, struggled when demand suddenly rose.
The pandemic made hospitals see the need for stronger inventory plans like:
Hospital leaders now try to balance keeping lean stock and preparing for sudden needs with flexible supply plans.
New technologies like artificial intelligence (AI) and workflow automation help hospitals manage supplies better. Some companies make tools that improve communication and staff workflow, helping hospital groups work more smoothly.
AI can look at lots of data such as past supply use, patient schedules, and supplier performance to predict future needs more correctly. This helps hospitals:
Using AI helps reduce costs while keeping good patient care.
AI tools also improve hospital communication. Automated phone systems and answering services reduce work for staff and help information flow faster and more clearly.
This helps supply staff work better by making it easier to coordinate and quickly respond to needs across departments. In hospital groups, shared communication tools improve teamwork and problem solving.
For AI to work best, hospitals need to connect clinical work with IT systems. Sharing data between clinical departments, supply managers, and buyers helps AI tools work well. This connection allows live supply updates and faster reactions.
AI can also use patient and schedule data to guess needed supplies, helping balance costs and service quality.
While hospital groups and new tech offer benefits, leaders must watch for policy issues. Hospital mergers can increase negotiating power, which may affect prices and competition.
Studies say policymakers often miss how much hospitals save on costs by working together. Hospital leaders need to show data on these savings to help shape good policies.
By knowing how important supply costs are, how hospital groups help, and how AI can support operations, hospital leaders can improve how their hospitals work. These changes help control inventory costs and manage risks in today’s healthcare world.
Horizontal inter-organizational arrangements, such as affiliations with multi-hospital systems, can reduce inventory costs by pooling resources and mutually managing supply chain risks, particularly under weak logistics conditions.
Affiliations can buffer hospitals from supply chain risks by pooling resources, which reduces the psychological stress of excess inventory accumulation for managers.
The effectiveness of system affiliations in mitigating inventory cost is more pronounced in areas with weak logistics services infrastructure.
Healthcare inventory management faces higher obsolescence rates compared to retail, as service performance outcomes dictate inventory levels rather than cost alone.
Research has primarily centered on vertical supply chain integration, with less attention given to horizontal arrangements among organizations.
Hospitals’ inventory costs are influenced by local demand uncertainties and the quality of logistics infrastructure, with system affiliations serving as mitigating factors.
Affiliation with local multi-hospital systems allows for pooled resources, leading to operational efficiencies that can be greater than those seen in independent hospitals.
Insights into inter-organizational arrangements can inform health policy debates about the operational performance of system-affiliated hospitals versus independent ones.
Examining specific areas like inventory costs provides a nuanced understanding of operational benefits from system affiliations, contrasting general aggregate performance measures.
Future research could explore the variability of hospital systems’ characteristics and analyze performance impacts across different environmental contexts.
