This is useful and interesting.

I tried searchig for [health care assisstant] and it didn't find anything. You may want to include some misspelling detection. It also didn't find anything for [health care assistant]. The two descriptions for [HCA] ask for more information.

Eventually you might want to include routes into each role. You may want to consider including information about protected terms - words like dietitian or art therapist are protected by law.

I do really like the ease of use and clarity though.
