A campaign to reduce unnecessary health tests, treatments and procedures has been launched.
The campaign, "Choosing Wisely", focuses on areas where evidence shows that tests, treatments or procedures done by health practitioners provide little or no benefit to a patient and could even cause harm.
A survey of New Zealand doctors found that half thought the provision of unnecessary tests, procedures or treatments was a serious or somewhat serious issue.
The Council of Medical Colleges worked with Consumer NZ to survey consumers about unnecessary tests, treatment and procedures.
The survey found that when they visited a doctor, 56 per cent of respondents generally expected the doctor to provide a prescription or send them for a test and 41 per cent of these agreed some tests or treatments which are carried out do not benefit the patient in any meaningful way.
Nearly 20 per cent believed their doctor had recommended a test or treatment to them which wasn't necessary.
