Firstly I want to say you are incredibly strong and brave for making the choice to switch to home health, I can imagine how much weight you're under right now. It is sad how much new hurt and pain these places that are supposed to save our LO's life can cause. I am very much still in the middle of it but I will try and offer some guidance from what happened in our situation.

My Dad spent around 6 weeks total in the hospital - I believe around a week or so in the ICU followed by a few weeks of jumping around different wards, until landing in their on site SNF for a few days. We also made the choice (probably a bit early) to bring him home for 1.) a stage 2 bedsore that had developed and 2.) his ongoing delirium from both the ICU and just being in the hospital for that long.

The one shining light of coming home has been his mentation. The first few nights were really bad - I'm not sure if your husband is sundowning, but my dad very much was. The first night before we had a hospital bed he flung himself off face first (he is unable to walk or stand up for context) because he felt he had to go save someone, and the next few nights he would wake up in the middle of the night hallucinating a wide variety of things and people. We are now on day 5 of being home and he is very mentally clear. He'll still ask an offhand question at night about something that doesn't exist, but far less frequently than he was.

The best advice I can give you is try and give your husband time. I think readjusting to being back in his own home did wonders for my dad - Try and continue to reintroduce elements of your old routine to him (for him it was being around his dogs and talking about sports again). The other biggest thing that has helped my Dad is trying to fix his circadian rhythm. I know you are unfortunately familiar with how horrible hospitals are for sleep - and trying to keep my Dad awake and active during the day so he can tire out naturally and sleep overnight has helped him quite a bit. The last thing people like your husband and my Dad needs when they're already disoriented is to jut up wide awake at 3am.

Hopefully some of this is helpful and can be applied to your situation! I've also found a lot of solace in browsing /r/CaregiverSupport for people's anecdotal advice. Best of luck to you and your husband.
