Often as not it's the reps who push the most get equipment into facilities. Not what may be the most suitable for the facilities. Equipment is purchased based on what is offered, without a lot of consultation.
The list of equipment in nursing homes & hospitals is getting more technical not simpler. The overlay mattresses & pumps , patient hoists ceiling & mobile, different model wheelchair & commode chairs. Electric beds. Clinical staff are expected to know if something goes wrong but often as not they are not shown or no-one knows.
