150.

What figure should we aim for?

Zero.

The NHS is the pride of Britain. It's an army of highly skilled and talented healthcare professionals, armed with the most cutting-edge therapies and medicines, and a budget bigger than the GDP of most countries in the world.

Yet avoidable failures are common. And the result is tragic deaths up and down the country every day.

Jeremy Hunt, the longest-serving Health Secretary in history, knows exactly what the cost is. In the letters he received from bereaved family members, he was constantly confronted by the heart-breaking reality of slip-ups and mistakes.

There is increasing conflict between public pride in the NHS and the exhausted daily reality for many doctors and nurses, now experiencing burnout in record numbers. Waiting lists are up, staffing numbers inadequate, and all the while an ageing population and medical advances increase both demand and expectations. With pressures like these, is it surprising that mistakes start to creep in?

This great British institution is crying out for renewal. In Zero, taking the broadest approach, thinking through everything from staffing to technology, budgets to culture, Hunt presents a manifesto for that renewal.

Mistakes happen. But nobody deserves to become a statistic in an NHS hospital. That's why we need to aim for zero.
