Ms Gains is general manager at the Threshfield Court Care Centre in Skipton, where she and her team work with residents who suffer with dementia using the Memory Lane programme.
The programme was pioneered by Barchester Healthcare and aims to enhance the lives of those with dementia by increasing their self-esteem and having a positive impact on their quality of life.
"We are all elated to have our work recognised and I feel very proud of our achievements. We now have a dementia care unit that is leading the way forward in the locality," said Ms Gains.
Innovations include the creation of an indoor garden; colour coding doors to make what's behind them easier to remember and using reminiscent items to stimulate memory and encourage self-expression.
Barchester's managing director, Mike Parsons, commented on the awards.
"Barchester Healthcare is delighted that the achievements of our care home managers have been recognised at the Independent Healthcare Awards."
He continued: "To have three finalists and two overall winners in such a cross-section of categories demonstrates our commitment to our home managers through a strong support structure and our own learning and development academy, as well as their individual commitment to excellence in quality care.
"We are very proud of all of their achievements," added Mr Parsons.
