Real-time visibility of medical surgical supplies, especially those supplies in the operating room sterile center core, is of great concern. Legacy inventory systems do not meet the requirements of the operating room. The operating room should be a major revenue generator for the hospital. Poor inventory controls, rising price of pharmaceuticals and medical materials plus decreasing reimbursement rates are perpetuating deficit business practices. The Cumulus System provides real-time visibility and accountability of medical surgical product as they are consumed, allowing for routine inventory reconciliations normally performed annually. Reconciliations that allow for inventory history and turnover enable accurate par levels for effective and equitable ordering. Cumulus provides real-time data allowing the operating room manager to be in control of their budget.
