The Starting Point: Availability Without Confidence
Riverside Health Network operated three hospitals and two outpatient centers with separate pharmacy spreadsheets. System totals looked adequate, yet clinicians regularly called other branches to locate antibiotics, anticoagulants, and emergency medicines. Manual adjustments and delayed consumption entries made the apparent balance unreliable.
A baseline review found that teams used one minimum level year-round and ignored supplier lead-time variability. Open purchase orders were not visible to ward pharmacists, while central buyers could not see urgent internal requests. The network measured total inventory value but not service-level failures.
Diagnosing the Real Causes
The project team classified every stock-out by demand, supply, data, or process cause. Most were not caused by extraordinary demand; they came from late replenishment, incorrect pack conversions, unrecorded ward issues, and orders concentrated with one supplier. This evidence redirected the program from simply increasing safety stock.
Criticality tiers were agreed with pharmacy and clinical leaders. Vital medicines received stricter service targets and daily exception review, while routine items used proportionate controls. Branch teams also defined when a shortage meant no physical stock versus no suitable batch available.
Baseline findings
- Static reorder levels
- Inaccurate unit conversions
- Delayed ward consumption posting
- Limited open-order visibility
- Excessive single-supplier dependence
Building a Shared Inventory Picture
Riverside migrated batch balances, open orders, and location data into a common inventory workflow. HealUDoc linked pharmacy movement with OPD visits, IPD admissions, and prescribing activity while restricting branch actions through roles. Central planners gained network visibility without taking routine control away from local pharmacists.
The team cleansed duplicate products and standardized purchase and issue units before enabling automated suggestions. Daily reconciliation focused first on controlled and high-velocity medicines. Confidence improved because users could trace each balance to receipts, transfers, dispenses, and adjustments.
Redesigning Replenishment and Escalation
Reorder points were recalculated using demand variability, target service level, and observed supplier lead time. The system proposed orders, but pharmacists reviewed unusual demand and known clinical events before approval. Vital-item exceptions appeared in a daily queue with named owners and escalation deadlines.
The network also formalized branch transfers before placing emergency external orders. Transfer decisions considered usable shelf life, transport time, and the sending branch's projected cover. Secondary suppliers were qualified for selected critical products to reduce concentration risk.
Interventions introduced
- Risk-based reorder parameters
- Daily critical-item exception queue
- Network-wide transfer workflow
- Backup suppliers for vital medicines
- Named ownership for unresolved shortages
Results After Six Months
The rate of critical-item stock-out events fell by 62 percent, while emergency purchase orders declined by 41 percent. Inventory value increased only 4 percent because excess routine stock was reduced as vital-item buffers improved. Near-expiry exposure also declined through branch rebalancing.
More importantly, the team could explain remaining incidents. Supplier failures, sudden outbreak demand, and posting errors had distinct owners and corrective actions. Leadership reviewed service level alongside inventory investment, preventing cost reduction from undermining clinical availability.
What Made the Improvement Sustainable
Technology provided visibility, but governance sustained the change. Pharmacy leaders reviewed parameter overrides, data quality, unresolved exceptions, and supplier performance every month. Branch comparisons were used for coaching rather than simplistic rankings.
Riverside's experience shows that more inventory is not the same as better availability. Reliable data, differentiated service targets, and fast cross-branch action produced the larger gain. Hospitals should begin by measuring why stock-outs occur before selecting a remedy.
“Once every shortage had a cause and an owner, we stopped treating stock-outs as an unavoidable part of hospital life.”
