Tom...do they have life alert buttons? That could be a real life-saver. There are also cell phones specifically for seniors that are used only for 911 calls. You might investigate that and be sure he has one at all times.
What about church groups, neighbors, friends calling at specified times throughout the day to check on them? Or if they don't want to keep answering the phone, can they call certain people at set times every day to "report in?" Do they have meals on wheels? That would be more people checking on them.
Do they have an extra bedroom? When my father was in that condition we investigated having a college student board with him free in exchange for light maintenance and just being there as much as possible. We had a young man all set to move in who loved to cook and would handle lawn care, etc, but my father suddenly got worse and a nursing home became the only option.
It's a tough decision to make. If they're happy and reasonably healthy, home is the absolute best place for them if at all possible.
Good luck
