It's time for NHS Change Day 2014 to begin.

What happens when the third largest organization in the world decides to change? We'll see in a few months.

Today starts the countdown to NHS Change Day, set for March 3, 2014.

This is a grass roots approach to change, not something ordered from the top down.

How it works is remarkably simple and engaging.

First, you make a pledge and post it for all to see.

All you need is an idea of what you could do to make a positive difference. Then you make a pledge - a simple promise to yourself and others that you will act on that idea and become a 'changemaker'.

If a pledge inspires you, you hit "like."

The more likes you give, the more you'll inspire others.Tell other people you like it too by sharing it on your social networks.

Join someone else's pledge.

Find a pledge that inspires you and if you think you can do it too, hit Join!

This is the second year. Last year saw 189,000 pledges to make things better. This year the goal is for 500,000.The organizers summarize:

Anyone can make a pledge. We ask everyone to embrace the energy of Change Day and to PLEDGE, SHARE, DO and INSPIRE. To make the NHS the best is can be. Let's do something better and courageous together. It's time for NHS Change Day 2014 to begin.

Here's a picture of the kick-off with three of the organizers, Jeremy Tong, Helen Bevan, and Sebastian Yuen, where Helen noted, "We're doing this because it fits with our values."  Jeremy advised the assembled crowd: "Listen to what people say... they'll be able to tell you the problems... but also act on what you hear."

From this side of the pond, I say, "Bravo!"
