Inventory Control Methods in a Long-Term Care Pharmacy: Comparisons and Time-Series Analyses.

Current inventory theory is based on simulated data and unrealistic formulae. Inventory replenishment processes are therefore commonly disrupted, and out-of-stock (OOS) events are unnecessarily frequent. OOS events at a large-volume, long-term care pharmacy in North Carolina were compared among 4 sequentially applied methods of inventory control: () a manual system without Six Sigma protocol, () a manual system with Six Sigma protocol, () a computer-assisted system with Six Sigma protocol, and () an automated system with Six Sigma protocol.
