Protecting poor NHS in regions so lacking (10)

I believe the answer is:

enshrining

I'm a little stuck... Click here to teach me more about this clue!

'protecting' is the definition.
Although both the answer and definition are present participle verbs, I cannot see how one could define the other.

'poor nhs in regions so lacking' is the wordplay.
'poor' is an anagram indicator.
'lacking' indicates named letters should be taken away.
'nhs'+'in'+'regions'='nhsinregions'
'nhsinregions' with 'so' removed is 'nhinregins'.
'nhinregins' with letters rearranged gives 'ENSHRINING'.
