Your description of your nursing/rehab center fit mine to a tee (except my therapists were much gentler). Are you sure we didn't go to the same one? Even those three nights in-hospital post-op, despite the intense pain, get one spoiled for the constant nursing attention and the fact that you know at all times who your care team (RN or LPN plus "patient tech" or nurse's aide) will be. When you get to the rehab center, it comes as a shock to find out that there's usually no more than one actual nurse per floor (and you might not get the same one every night), and the mostly unskilled aides have little authority to give you what you want or need. That call button in the hospital gets you near-immediate results; in the nursing home, it's not unusual to wait 5-10 minutes for a response and then up to half an hour for your request to be relayed to the nurse if necessary, much less have the nurse respond. A lot of them are freelancers and incredibly overworked--even when they're nice it's not unusual for there to be miscommunications. And in-hospital your OS and sometimes even your PCP visits daily and the place is crawling with doctors (especially in a teaching hospital, where there are fellows, residents and med students); in a rehab facility, it's not unusual for there to be no full-time or even part-time doctor around--and to be visited by him/her (or their PA) perhaps once or twice during your stay. Your OS is highly unlikely to visit you--it's vice versa (and a PITA cab-transfer-with-escort) should you need to see him. (The exceptions are rehab facilities attached to hospitals--e.g., R.I.C. and Bowman in Chicago and Rusk Institute in NY, and even then you're seen by a physiatrist--a specialist in recovery from trauma/surgery/stroke--rather than your OS. These days, only the most serious and complex cases get sent there, as well as high profile patients such as stars and politicians).
Oddly enough, the furnishings and amenities in my rehab facility (about the price of a high-end hotel room) were nicer and more modern than in the state-of-the-art teaching hospital where my surgery was done. Flat screen TV, nicer furniture, good climate control. One thing in common, though, and I think it's universal: ICKY FOOD! Starchy, bland, often processed and usually sparing and off-brand when it comes to condiments.
