The effectiveness of smoking cessation interventions in rural and remote populations: Systematic review and meta-analyses

A randomised trial of real-time video counselling for smoking cessation among rural and remote residents

INTRODUCTION

Despite its reach, very limited evidence exists on the effectiveness of real-time video counselling for smoking cessation (e.g. via Skype). This study compared the effectiveness of real-time video counselling for smoking cessation to (a) telephone counselling; and (b) a control among rural and remote residents.

METHODS

Between 25 May 2017 and 3 March 2020, a three-arm, parallel group, randomised trial, randomised 1244 rural and remote residents from New South Wales, Australia who smoked tobacco to: video counselling (4-6 video sessions); telephone counselling (4-6 telephone calls); or a control (printed materials). The primary outcome was 7-day point prevalence abstinence at 13 months post-baseline. Secondary outcomes were point prevalence abstinence at 4 months and 7-months post-baseline, prolonged abstinence, quit attempts, anxiety and depression.

RESULTS

For the primary outcome of 7-day point prevalence abstinence at 13 months post-baseline, there was no significant difference between video counselling and telephone counselling (14.6% vs 13.3%; (OR = 1.11, 95% CI (0.75-1.64), P = 0.61) or video counselling and control (14.6% vs 13.9%; (OR = 1.06, 95% CI (0.71-1.57), P = 0.77). For secondary outcomes at 4 months post-baseline, the video counselling group had significantly higher odds than the control of 7-day point prevalence abstinence (14.3% vs 8.2%; OR = 1.88, 95% CI (1.20-2.95), P = 0.006) and 3-month prolonged abstinence (4.9% vs 2.2%; OR = 2.28, 95% CI (1.03-5.07), P = 0.04). There were no significant differences for other secondary outcomes.

DISCUSSION

Video counselling increased smoking cessation in the short-term compared to a control although strategies to improve its long-term effectiveness are needed.

Short-term effectiveness of the national German quitline for smoking cessation: results of a randomized controlled trial

BACKGROUND

The objective of the present study was to examine the short-term effectiveness of the national German quitline for smoking cessation.

METHODS

A parallel-group, two-arm, superiority, randomized controlled trial with data collection at baseline and post-intervention (three months from baseline) was conducted. Individuals were randomized to either the intervention group, receiving up to six telephone counselling calls, or the control group, receiving an active control intervention (self-help brochure). The primary outcome was the seven-day point prevalence abstinence at post-assessment. Secondary outcomes included changes in smoking-related cognitions and coping strategies from pre- to post-assessment, the perceived effectiveness of intervention components, and the satisfaction with the intervention.

RESULTS

A total of n = 905 adult daily smokers were assigned to either the intervention group (n = 477) or the control group (n = 428). Intention-to-treat analyses demonstrated that individuals allocated to the telephone counselling condition were more likely to achieve seven-day point prevalence abstinence at post-assessment compared to those allocated to the self-help brochure condition (41.1% vs. 23.1%; OR = 2.3, 95% CI [1.7, 3.1]). Participants who received the allocated intervention in both study groups displayed significant improvements in smoking-related cognitions and coping strategies with the intervention group showing greater enhancements than the control group. This pattern was also found regarding the perceived effectiveness of intervention components and the satisfaction with the intervention.

CONCLUSION

The present study provides first empirical evidence on the short-term effectiveness of the national German quitline for smoking cessation, highlighting its potential as an effective public health intervention to reduce the burden of disease associated with smoking.

A smoking cessation intervention for rural veterans tailored to individual risk factors: A multicenter randomized clinical trial

INTRODUCTION

Rates of cigarette use remain elevated among those living in rural areas. Depressive symptoms, risky alcohol use, and weight concerns frequently accompany cigarette smoking and may adversely affect quitting. Whether treatment for tobacco use that simultaneously addresses these issues affects cessation outcomes is uncertain.

METHODS

The study was a multicenter, two-group, randomized controlled trial involving mostly rural veterans who smoke (N = 358) receiving treatment at one of five Veterans Affairs Medical Centers. The study randomly assigned participants to a tailored telephone counseling intervention or referral to their state tobacco quitline. Both groups received guideline-recommended smoking cessation pharmacotherapy, selected using a shared decision-making approach. The primary outcome was self-reported seven-day point prevalence abstinence (PPA) at three and six months. The study used salivary cotinine to verify self-reported quitting at six months.

RESULTS

Self-reported PPA was significantly greater in participants assigned to Tailored Counseling at three (OR = 1.66; 95 % CI: 1.07-2.58) but not six (OR = 1.35; 95 % CI: 0.85-2.15) months. Post hoc subgroup analyses examining treatment group differences based on whether participants had a positive screen for elevated depressive symptoms, risky alcohol use, and/or concerns about weight gain indicated that the cessation benefit of Tailored Counseling at three months was limited to those with ≥1 accompanying concern (OR = 2.02, 95 % CI: 1.20-3.42). Biochemical verification suggested low rates of misreporting.

CONCLUSIONS

A tailored smoking cessation intervention addressing concomitant risk factors enhanced short-term abstinence but did not significantly improve long-term quitting. Extending the duration of treatment may be necessary to sustain treatment effects.

Outback Quit Pack: Feasibility trial of outreach smoking cessation for people in rural, regional, and remote Australia

BACKGROUND

Tobacco smoking rates are higher in rural, regional, and remote (RRR) areas in Australia, and strategies to improve access to quit supports are required. This pilot study examined the feasibility of a smoking cessation intervention for people in RRR areas who smoke with the intention of using this data to design a powered effectiveness trial.

METHODS

A randomised controlled trial (RCT) of the feasibility of a 12-week 'Outback Quit Pack' intervention consisting of mailout combination nicotine replacement therapy (NRT) and a proactive referral to Quitline, compared with a minimal support control (1-page smoking cessation support information mailout) was conducted between January and October 2021. Participants recruited via mailed invitation or Facebook advertising, were adults who smoked tobacco (≥10 cigarettes/day) and resided in RRR areas of New South Wales, Australia. Participants completed baseline and 12-week follow-up telephone surveys. Outcomes were feasibility of trial procedures (recruitment method; retention; biochemical verification) and acceptability of intervention (engagement with Quitline; uptake and use of NRT).

RESULTS

Facebook advertising accounted for 97% of participant expressions of interest in the study (N = 100). Retention was similarly high among intervention (39/51) and control (36/49) participants. The intervention was highly acceptable: 80% of the intervention group had ≥1 completed call with Quitline, whilst Quitline made 3.7 outbound calls/participant (mean 14:05 mins duration). Most of the intervention group requested NRT refills (78%). No differences between groups in self-reported cessation outcomes. Biochemical verification using expired air breath testing was not feasible in this study.

CONCLUSION

The Outback Quit Pack intervention was feasible and acceptable. Alternative methods for remote biochemical verification need further study. SO WHAT?: A powered RCT to test the effectiveness of the intervention to improve access to evidence-based smoking cessation support to people residing in RRR areas is warranted.
