Here is the information I received from Tammy, on of the OTs.

OTs commonly make home visits to do assessments and suggest modifications if necessary, especially those working in the community.

You guys are on the right track with adding handrails and getting rid of rugs since those present a great risk for tripping and falling. Some other possible bathroom equipment may include bath benches and shower mats.  I would also recommend rearranging frequently used items to the main floor to minimize the need for Mary to climb up and down the stairs.  E.g., have her bedroom and/or install a bathroom on the first floor.  Since the stairs seem to present a greater risk for future falls, having some visual cues from the environment may also be advisable.  E.g., put coloured markers against the height of each step.  To enhance safety when getting up from her bed or chair, a standing pole could be set in place for her to hold onto and assist with standing.  Flooring in the home should also be made level (no raised decks), if it isnt already.  Lighting in the home should also be assessed since inadequate lighting reduces visibility, thus contributing to the risk of falls.

For her fractured wrist, there are many adaptive equipment that can be prescribed for Mary to use until she recovers.  An OT may introduce these to Mary to practice with and see which works best for her.  For the issues that you described, there are adapted hooks to pull zippers or large ringed zipper toggles for easier pulling.  There are tools with rubber straps to wrap around jar lids for firmer grip or, instead of using jars, perhaps Mary can use plastic tupperware with easy-to-open lids.  Certain cutting boards are also adapted with a device (i.e. pegs) to hold the food down so that you can chop with just one hand.

Im not exactly sure when these issues should be addressed but I think it would likely be while Mary is in rehab, just before discharge and then continue to assess after she returns home.
