Quitline is good value for money, says new study

August 21, 2017, University of Otago

A new study from the University of Otago, Wellington has found New Zealand's Quitline service is a highly cost-effective way to improve health and even saves the health system money.

The research used New Zealand data and computer modelling to study Quitline promotion in the mass media and the running of the Quitline service.

A year of running Quitline produced 4200 extra years of healthy life in the population and saved the health system $84 million over the remaining lifetimes of the New Zealand population, says one of the study authors Professor Nick Wilson, from the Department of Public Health at the University of Otago, Wellington.

The health benefit was particularly obvious for Māori, with three times greater per capita health gains for Māori than non-Māori.

Professor Wilson says this finding suggests Quitline will be helping reduce health inequalities, as also found with other research on tobacco-control interventions.

"The reality is probably even more favourable for health gain since the modelling only covered the 16 most important tobacco-related diseases and many more diseases are related to smoking."

"The benefits also include financial savings for smokers who quit and productivity gains associated with workers who don't die prematurely from smoking."

But Professor Wilson says this research needs to be put into a broader context of what is most effective for reducing smoking.

"Our research suggests that much more health gain would probably be achieved by regular increases in and from various 'tobacco-endgame interventions'."

These include a sinking lid on tobacco sales, or a package of increasing tobacco tax while also phasing out sales through retail outlets and creating a "tobacco-free generation".

Some of these types of approaches are detailed in the recently launched Action Plan for achieving Smokefree Aotearoa by 2025.

Furthermore, some of these measures might become more effective as e-cigarettes become a more viable alternative, particularly if higher tobacco taxes make e-cigarettes a far cheaper option, Professor Wilson says.

"We would recommend that the Government continues to fund improvements to the Quitline and other cessation services – but also would strongly encourage work on endgame strategies to ensure that New Zealand's Smokefree goal is achieved by 2025."

"These strategies are likely to deliver more health benefits and also save far more taxpayer dollars than the more incremental steps being currently taken to reduce smoking," he says.
