The Auckland District Health Board must lift its performance, its chief executive says. The board has released its results for the first quarter of 2012-13, and has fallen short of four performance targets. While the board achieved its goals of shorter waits for cancer treatments and increased immunisation, it narrowly missed the targets for shorter stays in emergency departments, better help for smokers and improved access to elective surgery. It fell well behind its aim for more heart and diabetes checks. Chief executive Ailsa Claire says she is determined the board will reach its goals.
