UX Considerations for CCE Monitoring Devices

Effective CCE displays are crucial for maintaining vaccine integrity. Health facility staff rely on these displays to provide unambiguous and timely information to ensure the safety of stored vaccines.
Following the publication of the WHO PQS EMS standards in 2022, multiple manufacturers are developing next-generation CCE, many of which will include new digital displays. This moment offered a unique opportunity to review the User Experience (UX) patterns and practices that have been previously implemented in CCE monitoring systems, and consider which patterns will provide the greatest value in the health facilities of tomorrow.
In late 2024, New Horizons developed the following document as a resource for teams designing and developing digital displays for E006 devices:
This document outlines a set of patterns and practices for CCE displays that New Horizons found particularly effective. It reflects the collective perspective of our designers and engineers, based on our experience using and designing cold chain equipment. This resource is not associated with WHO PQS and it is not part of the EMS standards. Our intention for this work was to articulate and refine our own design thinking in this domain, so it should not be interpreted as prescriptive and inflexible. We are releasing it publicly in the hopes that other teams may find it useful for their own efforts and, ideally, provide feedback to identify gaps and refine these perspectives.
We encourage you to review this document and consider how these patterns can be applied to your CCE monitoring system. Your feedback is valuable to us, and we welcome any questions or comments you may have. If you have any questions about the guidance or would like to discuss its implementation further, please feel free to reach out. We are happy to provide additional information or setup a call to discuss how these guidelines can benefit your specific use cases.
