National Services Scotland (NSS), a public body that provides strategic support to the NHS in Scotland, is exploring the option of replacing four child health surveillance legacy systems that are proving to be inefficient and expensive.

A prior information notice outlines that the four systems are interconnected and were originally developed up to 15 years ago.

NSS claims that the systems have done well to support the NHS, but are now outdated. It stated: "They now have a number of challenges including legacy technology, inflexibility, poor architecture and poor value for money.

"All of the above results in a high cost of ownership, through inefficiency and duplication of effort."

NSS is now investigating the options for improving or replacing some or all of the systems, where the new solution would ideally already be in use or be capable of providing a service to a population of comparable size to Scotland. There are approximately 5.3 million people living in Scotland, one million of whom are children under 18 years old.

The new solution may also not be restricted to just children, so that its functionality could support patients of any age, such as for those over 65 requiring flu vaccinations.

NSS is considering all delivery models, including hosting by a third party, as long as the service provider is based in Scotland.

The chosen vendor will need to provide an online interface to support users in a variety of care settings, such as primary, secondary and education, as well as support agile development techniques.

It also requires that the chosen provide migrate the data in the existing systems to the new solution to "provide seamless continuity in the operation of all child health programmes".
