I don't use slice of life myself however, I have seen that it is broken up into "modules" now so that you can just use the elements you like from the mod?
Otherwise, there is Private Practice by SimRealist & Healthcare redux by adeepindigo. I've used Private Practice and I liked it, but I think there's been a lot of updates since I last used it, so I can't comment on the current version of the mod. Healthcare redux I've yet to check out but I've watched some YouTube videos on it and it looks interesting, if not a little bit buggy when it comes to booking doctors appointments etc. But you can check them out for yourself and see if they are what you are looking for :)
