Abstract This preprint reports a retrospective pooled analysis of prospectively collected workplace routine follow-up data from a multimodal tobacco cessation program with 12-month extended aftercare in Germany. The analysis includes 742 employees from 52 corporate seminars conducted between 2010 and 2024. Abstinence data were collected externally by the participating companies' health or human resources departments. At follow-up (mean: 6.5 months; range: 0.65–25.0 months), 683 of 742 participants were abstinent, corresponding to a participant-level success rate of 92.0%. In addition, the master dataset documents a seminar-based overall rate of 93.6%, with individual seminar rates ranging from 70.0% to 100.0%. The program combined cognitive-behavioral therapy, clinical hypnotherapy, stress competence training, self-medication treatment, anti-craving techniques, structured relapse prevention, and 12-month extended aftercare. The findings suggest that a high-intensity, multimodal care model with prolonged aftercare may be associated with abstinence rates well above published routine-care benchmarks. At the same time, the record is explicit about its main limitations: no randomized control group, no formal biochemical verification, variable follow-up duration, and different levels of aggregation for the two main outcome measures. The record includes full-text versions in English and German.
