I'm not sure if everybody on here quite understands just how our care/nursing home system works. I know you are a similar age to me so may have had parents who have "gone through" the system or even part of the system now. It's also important to distinguish between care homes and independent living arrangements in which elderly people live in communities.
Essentially people go in there once it has been decided that they can no longer be cared for in their own home, bearing in mind that most will already have had carers coming into their homes previously. They are mostly infirm to some degree or have some form of dementia. I have personal experience of 3 family members in care homes, my mum, who lived 3 months, my mum in law, who lived 10 months, and my wife's uncle, who lasted nearly 2 years. The average time spent in care homes is around 12 months, so my experience is pretty much indicative of that. So an average size care home with 100 residents would, on average, experience 2 deaths per week. All families are asked to sign an agreement on resuscitation/non resuscitation within 48 hours of admittance, and once the resident dies, such is the demand for beds that families are requested to have the room vacated of personal belongings by midnight the same day.
The standards of care homes varies greatly, and for most of us who rely on state subsidised beds it can be a heart wrenching experience for families as they have to choose between the few beds on offer. But the bottom line here is that the staff in these homes are dedicated, caring and very experienced in dispensing palliative care. In the event that any residents actually contract CV-19, then they are already in the best place to see out their final days. The majority are already so ill that hospitalisation would be pointless and they would be taking up an ICU bed of somebody else who would be more likely to pull through.
The worst thing about this virus for people in care homes is that they are currently prevented from seeing their loved ones. Although I believe they are looking at ways of lifting these restrictions with the use of PPE and social distancing.
