Hourly Rounding

I manage a med-surge unit and we started hourly rounding in April. We were doing great at first but staff's motivation really seems to have slipped. There seems to be a big disconnect between "it's just another task I have to do" and the bigger picture of patient trust, safety, and satisfaction. If anyone has been thru this before, how did you "hard-wire" hourly rounding on your unit? How do you hold staff accountable? Thanks
