Smoking remains a significant global public health issue, leading to numerous preventable deaths and disabilities annually. Telephone counselling is a recommended intervention for smoking cessation, offering accessible support to a wide range of people who smoke. This study aimed to evaluate the long-term effectiveness of the German quitline for smoking cessation.Introduction: A parallel-group, two-arm, superiority, randomized controlled trial was conducted between October 2021 and November 2023. People who smoked daily and were willing to quit received either up to six telephone counselling calls (intervention group) or a self-help brochure (control group). Seven-day point prevalence abstinence from cigarettes and tobacco at 12 months and prolonged cigarette and tobacco abstinence from 3 to 12 months after the start of the intervention were assessed. Further, the use of additional cessation aids was assessed.Methods: A total ofResults: n = 905 participants were randomized (intention-to-treat sample). The intervention group (n = 477) exhibited higher rates of prolonged cigarette abstinence (31.7% vs. 17.8%) and prolonged tobacco abstinence (30.8% vs. 15.2%) compared to the control group (n = 428) at 12-month follow-up with corresponding odds ratios of 2.2 (95% CI [1.6, 3.0]) and 2.5 (95% CI [1.8, 3.5]). Seven-day point-prevalence cigarette abstinence was not statistically significant (OR = 1.3, 95% CI [1.0, 1.7]). E-cigarettes were the most commonly used additional cessation aid (46.0%), followed by electronic media (31.0%) and nicotine replacement therapy (26.2%). Telephone counselling provided by the national German quitline for smoking cessation demonstrates effectiveness in promoting long-term abstinence from cigarettes and tobacco. Increased awareness and use of the quitline could promote cessation rates in Germany. Given the rising popularity of novel nicotine consumer products, counselling protocols should incorporate information on their risks and potential as cessation tools. Smoking is a major global health problem, causing many preventable deaths and disabilities each year. Telephone counselling is a recommended method to help people quit smoking because it provides accessible support. This study examined the long-term effectiveness of the national German Smokers Quitline. Daily smokers who wanted to quit smoking were divided into two groups. One group received up to six phone calls from the national German Smokers Quitline, the other group received a self-help brochure. We measured how many participants stopped smoking for at least 7 days 12 months after the start of the intervention (7-day point prevalence of abstinence). We assessed long-term cigarette and tobacco abstinence, i.e., how many participants abstained from cigarettes/tobacco for a period of 9 months after the start of the intervention. We also examined the use of other cessation aids. A total of 905 participants took part in the study. The telephone counselling group had higher rates of long-term cigarette (31.7% vs. 17.8%) and tobacco abstinence (30.8% vs. 15.2%) compared to the other group. The odds of quitting were significantly higher in the telephone counselling group. However, the 7-day point prevalence of abstinence did not differ between the groups. Many participants used additional cessation aids, with e-cigarettes being the most common. In conclusion, telephone counselling provided by the national German Smokers Quitline is effective in helping people quit smoking long term. Increasing its awareness could improve smoking cessation rates in Germany. Counselling should include information about the risks and benefits of new nicotine consumer products.
