One in 10 New Zealanders uncomfortable asking doctors whether a test or treatment is necessary

One in 10 Kiwis don’t feel comfortable asking their doctor about whether a treatment or test is necessary, a survey by Consumer NZ and the Council of Medical Colleges has found.

The annual survey was carried out as part of the organisations’ Choosing Wisely campaign, which encourages people to ask their health professional four questions when a test or treatment is suggested:

  1. Do I really need this test, treatment or procedure?
  2. What are the risks?
  3. Are there simpler, safer options?
  4. What happens if I don’t do anything?

Consumer NZ chief executive Sue Chetwin said people should feel able to question health care treatment options.

'Understanding why your doctor is considering a test – and weighing up the benefits and risks – is every patient’s right.

'Ask what is likely to happen if you do – or don’t – have a test or procedure. Are there potential side effects? What are the chances of getting results that aren’t accurate? Could that lead to more testing or another procedure?

'Just by having these discussions you and your doctor will be clearer on what is the best thing to do for your health and wellbeing.'

The survey also found 21 percent of consumers felt their doctor had recommended a test or treatment that wasn’t necessary. Of those, 24 percent said they went ahead and had it anyway. Eighteen percent ignored the doctor’s recommendation.

Thirty-five percent of consumers felt some tests or treatments did not benefit the patient.

While most felt their doctor always (40 percent) or often (30 percent) involved them in decisions about their care, one in five thought this only happened sometimes.

Choosing Wisely medical director Dr Derek Sherwood said there is mounting evidence that more tests and procedures don’t always equal better care.

'While modern medicine has given us more ways than ever to diagnose and treat illness, sometimes, the best option may be to do nothing.

'Tests, treatments and procedures have side effects and some may even cause harm. For example, CT scans and x-rays expose you to radiation; overuse of antibiotics leads to them becoming less effective; a false positive test may lead to painful and stressful further investigation.'

As well as encouraging patients to ask their doctor about tests and treatments, the Choosing Wisely campaign has comprehensive information for health professionals about which tests, treatments and procedures to question.

Choosing Wisely sponsors are the Council of Medical Colleges, Southern Cross Health Society, Pacific Radiology and PHARMAC. Consumer NZ and the Health Quality & Safety Commission are Choosing Wisely partners, and there is wide health sector support for the campaign.
