In 2015 the Royal College of Nursing in Wales surveyed 1186 members across nursing sectors in all parts of Wales.
Nurses across Wales agreed that the most important change we could bring about was to ensure that there were safe levels of nurse staffing in hospitals in Wales.
Too few nurses mean increased mortality, increased infection rates, more patient falls, more pressure sores, poor nourishment and hydration and mistakes administering medication.
It's vital for patient safety and well-being that there are enough nurses with time to care.
We know that laws change the behaviour of big organisations such as health boards by creating new standards of what is acceptable, so we decided to take action.
Working with the RCN, Kirsty wrote a draft law, called a Bill.
The purpose of the Bill was to ensure that nurses are always deployed in sufficient numbers to:
In short, give nurses the time to care.
There was lots of support for our idea. Many nurses came to the Welsh Assembly and hundreds more spoke to their AMs, telling them why the Bill was so important.
We told politicians that the current system of ensuring nurse staffing levels wasn't good enough and that a law was needed to make health boards act.
Professor Mark Drakeford, then Minister for Health and Social Services, agreed and after extensive discussion and some changes, the Bill was passed by Assembly Members on 10th February 2016.
On Monday 21st March 2016, the Bill was approved by the Queen and it became a law.
But it doesn't end there. We will now hold politicians to their word and make sure that the law is enforced.
