If they have an OT on staff, they should look into positioning and have them write up orders. My daughter is an OT...and then her clients have to be moved to different positions (with supports) every 4 or 6 hours to prevent skin break down.
Yes, I would at least look into them handling that better.

I have to admit, with my mom on bedrest for her ulcerated veins, I started to give her a skin break down from the way I had her leg positioned...extra support under her ankle was too much pressure. It happened surprisingly fast. But since they are the professionals, yes, I would expect that bed sores should be preventable!

I wouldn't say that bed sores can be 100% prevented, but better procedures (ie more moving) should reduce the risk of bed sores. But if a person is bedridden 24/7 my guess is that bed sores are inevitable.

But talk to another doctor to get a second opinion. And perhaps a third opinion.

Gentle hugs

Pressure sores are very hard to prevent for a lot of reasons.

Older peoples skin is very thin.

Every time you turn them or reposition them to get the pressure off one area or areas, you put pressure on another area or areas!

Also the poor old folks just get tired of being moved so much and can feel like they are not ever allowed to get any rest.

There are pressure bandages that can help and when sitting up a doughnut pad to sit on can be helpful.

Bedsores are never completely preventable even under the best circumstances, especially in the elderly.

If the sores become chronic after a stay in whatever facility he's in, then I would address that with the staff. It's not complacency, you simply trust the facilities he's been in. The less exercise your father get's the more likely he'll get bed sores. Any pressure on any area under a bone can and will be blood flow problem and even if you move the patients often, there's still friction etc.

I would talk to the staff wherever he stays to see what precautions they have in place to help prevent bed sores.
