Epistemic Status: High confidence theoretical.

Firstly, I'd find a suicide prevention hotline, and I'd make sure literally everyone who worked in my house-of-healing could handle working for that hotline, by having them do it for a month. I would offer the orientation materials free in the waiting room, right next to the comic books.

Secondly, I'd find a law firm focused on debt collection, and I'd hire them full-time as insurance billing specialists. No one likes bureaucratic excrement, especially the sort that kills diabetics.

Thirdly, I would offer free legal consultation, in the same office. Wills are an obvious service, and so is negotiating for disability accommodations. There are enough people with law degrees who'd take a modest salary in exchange for job security and the knowledge that they're doing some good in the world; this isn't difficult.

Fourthly, I would make darn sure the decor was aesthetically pleasing, and also educational. I'd go looking around on Etsy, maybe commission some oil painters, but the job is to frame the human body as something fantastic, rather than just gross or alien. Embroidered anatomical models, flying cyborg brains with rainbow lasers, music albums bought on Bandcamp and streamed through the speakers.

Fifth, there would be a sizeable book budget for the waiting room. Book curation would be an important job. My default assumption is that children's books and newspaper comic collections would be ideal, on account of being the sort of thing you can enjoy even if you have to put it down in a hurry. At least two reception desk workers would have to read a book and sign off on it before it gets added to the shelf.

Sixth, there would be a sizeable snack budget. I might just hire a chef. No one should work hungry, no one should work tired. This isn't endurance training, which you can and perhaps should do on your own time.

Seventh, all toys for children would be curated based on ease of washing, and the children would get a sink and/or washing machine to wash them in. Kids love playing with water, and if water is expensive, simply tell them so. Toys must be washed daily.

Critique would be welcome, as would signal-boosting. I want reasonably optimal Generic Hospital and/or Doctor's Office institutional blueprints to reach the eyes of the people who desire to run, build, or improve such institutions ASAP.
