Please note: This is a Sole Source Notification. Vendor Name: STChealth. The STChealth forecast is a fully developed, tested, delivered and supported product that is available as a web service component that can be integrated into USIIS. No other standalone vendor supported system exists. USIIS is internally developed, maintained and supported, making the integration of the forecasting software unique. The UDOH USIIS Program has employed STChealth’s forecast software as a component of USIIS since 1998. The technical compatibility, ease of integration, clinical and technical quality, and clinical and technical support make it unique. STC has a proven record in public health informatics and software services, enabling them to comply with the Centers for Disease Control and Prevention requirements for state immunization information systems. No other forecast product is available that is not open source or that requires significant customization to implement; USIIS does not have resources to implement those types of products.
