Hi Colin,
It depends on how the current page structure is defined. If the ‘Care & treatment’ page is actually the parent page of the pages you need to search, there might be a really easy solution: Knowledge Base – Limiting results to specific posts by parent ID
Another possibility is to enable categories to pages (or any other taxonomy) and then only include the category you want the results from.
To have categories with pages, there are multiple plugins available, for example: Post tags & Categories for pages
