@BartholomewB, My understanding ( or better say misunderstanding )stemming from the Spanish “ Capellán” was that it meant Catholic, in charge, and a priest.
In the US I met Baptist , Episcopalian persons in charge of facilities ( hospital, jail…) who were “ Chaplains”.
Then I learnt that there are Chaplaincy studies and courses to help acquire knowledge and skills for Spiritual and pastoral care in religious and secular facilities.( organizations, communities…)
And to conclude I was sometimes addressed as “ Chaplain So and So” as a Visitation Minister by Christian non -Catholic persons deducing it might be related to the service and the connection with Chaplaincy and spiritual care. Not that it always meant in charge then either …
All very loving memories though it took time to understand. If I do… Perhaps there is more that I don’t know, but truly it went beyond a priest in charge as I had thought.
That was what I learnt about Chaplains and Chaplaincy.
And for the OP , the parishes I knew had already established friendly connections with the facilities in the area that might require Visitation or Sacraments ( hospital, nursing homes…)and to the best of my knowledge, there were no issues coordinating what was necessary from a Catholic perspective in the best interest of the people served.
