Drug shortages have topped the list of challenges facing hospital pharmacies for seven years running. In Bluesight’s 2026 Hospital Pharmacy Operations Report, 78.3% of the 437 pharmacy professionals surveyed named shortages their top operational challenge, yet nearly 70% of pharmacies still manage them primarily with spreadsheets, and only about 1 in 6 use dedicated shortage software.
Below, we answer the questions pharmacy leaders, supply chain teams, and procurement directors are actually asking about drug shortages and the technology built to predict and manage them.
What Causes Drug Shortages, and Why Do They Keep Happening?
Drug shortages are rarely caused by one thing. The most common contributors are:
- Manufacturing and quality problems. Production delays and capacity constraints have historically caused roughly 30% of drug shortages. Generic injectables are especially vulnerable because manufacturers typically run multiple products on the same line, with no dedicated backup capacity if one run fails.
- Thin manufacturer redundancy. Many generic drugs are made by only one or two manufacturers. When one of them has a quality issue or halts a line, there’s often no other supplier positioned to absorb the demand.
- Raw material and API sourcing. A large share of active pharmaceutical ingredients are manufactured overseas, which means geopolitical events, plant inspections, or export restrictions in another country can ripple into a US shortage months later.
- Natural disasters and disruptions. Hurricanes have repeatedly triggered major shortages, including a storm that knocked out more than 50 drug-manufacturing plants in Puerto Rico, and a more recent hurricane that idled a plant supplying a majority of the nation’s IV fluids.
- Demand surges. Sudden increases in demand (a bad flu season, a new use for an existing drug) can outpace supply even when nothing has gone wrong on the manufacturing side.
- Economic incentives. As older generic drugs go off-patent, thinning margins can push manufacturers to deprioritize or discontinue low-profit products entirely.
Because many of these causes are structural rather than one-off events, most experts agree drug shortages aren’t going away. The more realistic goal is reducing how much warning time pharmacies have, and how well they use it.
How Many Drug Shortages Are Active in the US Right Now?
Most hospital pharmacies are managing 10 or more active shortages at any given time, and some surveys put the number as high as 40+ when smaller, localized shortages are included. National shortage counts have been at or near decade highs for several years running, with essential drug categories – anesthetics, chemotherapy agents, IV fluids, and ADHD medications among them – recurring on the list.
A quick note on sources: the FDA’s drug shortage database and the ASHP/University of Utah Drug Information Service list are the two most-cited public sources, and they don’t always agree. ASHP’s list tends to reflect real-world clinical impact (including shortages the FDA hasn’t yet listed), while the FDA relies on manufacturer self-reporting, which can lag actual availability by weeks or months. Pharmacy teams generally need to track both, because a drug can come off the FDA list while remaining genuinely hard to source.
What Does a Drug Shortage Management Plan Actually Include?
ASHP’s guidelines on managing drug product shortages lay out a structured framework that most hospital plans are built around:
- Establish a shortage response team with a designated point person: no single person can manage all shortage planning alone, so plans typically name specific owners for sourcing, clinical review, and communication.
- Assess inventory on hand system-wide, not just in the central pharmacy: including inpatient units, ambulatory clinics, automated dispensing devices, floor stock, code carts, and prepared trays, in order to estimate how long the organization can operate before the shortage becomes clinically felt.
- Identify and stock-check therapeutic alternatives before they’re needed, since a shortage’s ripple effect often shifts demand onto the backup drug.
- Build a patient prioritization framework for cases where supply genuinely can’t meet demand, often through a resource allocation committee that includes pharmacy, nursing, and ethics representation.
- Update ordering, storage, and dispensing procedures as needed: this might mean changing concentrations, packaging, or where a drug is stocked.
- Communicate proactively with clinicians, patients, and administrators as the situation evolves, rather than only when a shortage becomes a crisis.
The organizations that handle shortages best generally aren’t the ones with zero shortages. Instead, they’re the ones with an infrastructure in place before a shortage hits, so the response is procedural rather than improvised.
How Far in Advance Can Technology Predict a Drug Shortage?
This varies by vendor and methodology, but the range you’ll see across the market runs from about 30 to 90 days of advance warning, depending on the data sources and modeling approach:
- Platforms that monitor market-wide signals like ShortageCheck (fulfillment delays, demand surges, usage trends across a network of health systems) tend to flag risk 30–90 days ahead of formal shortage listings.
- Platforms built on regulatory and compliance data (inspection histories, warning letters, financial health of manufacturers) can sometimes forecast further out — some claim 4-6 months of lead time on manufacturing-related risk specifically.
- Academic and machine-learning models trained on pharmacy purchasing data have shown meaningful but more modest accuracy. One peer-reviewed model correctly classified shortage risk about 69% of the time, roughly a month in advance, using purchasing data alone with no manufacturer-side visibility.
The honest takeaway: no tool eliminates false positives or guarantees a specific shortage will or won’t happen. What good shortage prediction technology actually buys you is runway: enough notice to build a plan calmly instead of scrambling once the drug is already gone.
What Is Drug Shortage Prediction Software, and How Does It Work?
At a high level, drug shortage prediction software combines two things: a way to see risk coming, and a way to know what to do about it once it arrives. Most platforms in the category share a similar architecture:
- Signal monitoring: tracking market-wide indicators like wholesaler fill rates, purchasing spikes, manufacturer inspection and compliance data, and sometimes network-wide usage data pooled anonymously across many hospitals.
- Risk scoring against your own inventory: the prediction only becomes useful once it’s layered against your actual days-on-hand for that specific drug at your specific facility. A drug with 200 days of inventory sitting in your system is a very different problem than one with three days left.
- Workflow and communication tools: because once a risk is flagged, someone has to act on it. The best platforms centralize scenario planning, task assignment, and documentation so the response doesn’t live in scattered emails and spreadsheets.
This is the core idea behind Bluesight’s ShortageCheck: it monitors market-wide signals across the acute care space and combines that with a hospital’s own inventory data, so pharmacy teams aren’t just told “this drug might go short”; they’re told whether it’s actually a problem for their specific supply, and given the tools to plan a response.
What Should You Look For in Drug Shortage Management Software?
If you’re evaluating vendors, the questions worth asking are less about feature checklists and more about these four things:
- Lead time and accuracy, together. A tool that predicts 90 days out but with a high false-positive rate can cause more alert fatigue than it prevents. Ask how accuracy is measured and over what time horizon.
- Does it use your own inventory data, or only market data? Market-wide shortage signals are useful, but they mean very little without being weighed against your actual days-on-hand. The most useful tools do both.
- Is it a monitoring tool, or a workflow tool, or both? Some platforms are essentially early-warning dashboards; others also give you a place to plan, assign tasks, document decisions, and build institutional memory for the next time a similar shortage hits.
- How does it handle sourcing? Some tools stop at “here’s the risk”; others connect you to alternative supply (secondary marketplaces, 503B outsourcing facilities, or direct manufacturer catalogs) when your primary wholesaler comes up short.
How Is AI Changing Drug Shortage Forecasting?
AI hasn’t solved drug shortages, but it has meaningfully changed what “early warning” means. A few shifts worth knowing about:
- Moving beyond self-reported data. Historically, shortage tracking relied heavily on manufacturers reporting problems after the fact, often too late to help. AI-driven models increasingly pull from purchasing data, dispensing patterns, and compliance signals that surface risk before it’s officially acknowledged.
- Reducing false positives. Early shortage-alert systems suffered from noisy signals that led to alert fatigue among clinicians. Newer models that combine real-world purchasing and utilization data with market-wide signals are specifically designed to cut down on that noise.
- Predicting more than the shortage itself. Some newer tools now forecast manufacturer-side risk (plant inspections, financial health) rather than waiting for a shortage to already be visible in the market, pushing the prediction window earlier in the chain, closer to the root cause.
What’s the Difference Between Reactive and Proactive Shortage Management?
Reactive management starts the moment a drug is unavailable: pharmacy staff scramble to find substitutes, call distributors, and adjust orders under pressure, often while the clinical team is already asking questions about patient impact.
Proactive management starts weeks or months earlier, when a risk signal first appears: the team reviews inventory, checks alternative sourcing, and if the drug turns out to matter clinically, has a plan ready before the shortage becomes visible to frontline staff at all.
The difference isn’t just stress levels. Hospitals collectively spend an estimated 20 million hours a year managing drug shortages, at a labor cost approaching $900 million annually – nearly double what was reported just a few years earlier. That cost is almost entirely a function of how much lead time a team has. More lead time means fewer emergency phone calls, less overtime, and fewer rushed clinical substitutions.
How Can Pharmacy Teams Reduce Time Spent Managing Shortages?
Based on where hospitals see the biggest time savings, a few practical levers stand out:
- Consolidate data sources. Teams juggling separate systems for inventory, wholesaler data, and shortage lists lose hours just pulling information together before they can even start solving the problem.
- Filter for relevance early. A shortage list with thousands of drug names is nearly as useless as no list at all. Narrowing signals to a hospital’s own purchase history and formulary cuts the noise dramatically.
- Centralize communication. A large share of shortage-management time isn’t spent sourcing drugs; it’s spent relaying the same information across sites, shifts, and departments. Built-in communication and documentation tools reduce that duplicated effort.
- Build a reusable playbook. Many shortages recur or resemble past ones. Documenting what worked (which alternative was used, which supplier came through) turns each shortage into institutional knowledge instead of a one-off fire drill.
Quick Answers: More Common Drug Shortage Questions
Is drug shortage software worth it for a smaller hospital or health system? Even smaller systems report meaningful time savings, mainly because manual tracking scales poorly. A handful of pharmacists juggling 10+ shortages on spreadsheets often struggle more, proportionally, than large systems with dedicated supply chain staff.
Can technology actually prevent a drug shortage? No. No software can create supply that doesn’t exist. What it can do is extend the amount of notice a hospital has, which allows for sourcing alternatives, adjusting inventory, and communicating with care teams before the shortage becomes a clinical emergency.
Do drug shortage tools replace a pharmacist’s clinical judgment on alternatives? No. Most platforms are explicit that clinical decisions about therapeutic alternatives remain with the pharmacy team. The technology’s role is visibility and lead time, not clinical recommendation.
How much does a drug shortage cost a typical hospital? Estimates vary by hospital size, but national data suggests shortage management now costs US hospitals collectively nearly $900 million a year in labor alone, and about three-quarters of pharmacies report exceeding their supply chain budget because of shortages.
What’s the difference between a shortage and a discontinuation? A shortage is a temporary supply-demand imbalance that’s expected to resolve. A discontinuation means the manufacturer has permanently stopped producing the drug, which requires a different kind of planning, since there’s no “waiting it out.”
See It in Action
Drug shortages aren’t going away, but the amount of warning your team gets – and how well-prepared you are to act on it – is largely within your control. ShortageCheck combines market-wide predictive signals with your own inventory data to flag real risk up to 90 days out, and gives your team a single place to plan, document, and coordinate the response.
