Vaporised nicotine and tobacco harm reduction for addressing smoking among people living with HIV: A cross-sectional survey of Australian HIV health practitioners' attitudes

Background: Tobacco smoking is a major cause of morbidity and mortality among people living with HIV (PLHIV). Due to the limited success of standard abstinence-focused smoking cessation strategies in this population, there is growing interest in tobacco harm reduction (THR) approaches as an additional strategy to address these high smoking rates. This study explored the attitudes of health practitioners who provide healthcare to PLHIV towards THR.

Methods: 179 Australian health practitioners who provide healthcare to PLHIV completed an online survey that measured their attitudes towards THR approaches, including switching from cigarettes to e-cigarettes or vaporised nicotine products (VNPs).

Results: Respondents supported the concept of THR but were undecided on the role of VNPs. Respondents most commonly reported 'don't know' or 'undecided' responses to statements regarding VNPs. More respondents, however, agreed than disagreed that switching from smoking to long-term vaping could reduce risk (36% and 22% respectively) and be an effective strategy to help PLHIV to quit smoking (37% agree and 17% disagree). Only a minority of respondents (20%) agreed that VNPs are too harmful to recommend to patients, however around half (53%) were undecided.

Conclusions: Despite supporting the principle of THR, health practitioners may require more evidence and knowledge about VNPs before being willing to consider them as a suitable intervention strategy.
