These tables show the level of certain procedures provided to people in your DHB area compared to DHBs in other parts of New Zealand. The ratio has been standardised – in other words, it takes into account the particular sex, age, ethnicity and social deprivation mix of your DHB’s population.
If all DHBs were providing services at the same level, they would all be at 1. A rate higher than 1 indicates that the DHB is providing more than the average rate in New Zealand, and a rate lower than 1 indicates that the DHB is providing less than the average rate in New Zealand.
Intervention rate analysis does not necessarily indicate what the right rate might be, but compares individual DHBs with the national mean, taking DHB population demographics into account.
