{"doi":"10.18332/tpc/203869","title":"The initial and ongoing effect of the COVID-19 pandemic on the reach and impact of a US state tobacco quitline","abstract":"INTRODUCTION: This study examines the long-term effect of the COVID-19 pandemic on the reach and impact of one US state tobacco quitline while taking into account quitline offers of free nicotine replacement therapy (NRT). METHODS: This is a pre-post analysis from January 2017 through June 2023 of the reach and impact of Michigan's tobacco quitline after the start of the COVID-19 pandemic. We assess quitline reach (number of callers per month), effectiveness (self-reported 30-day abstinence at 6 months), and impact (number of new ex-tobacco users per month). We examine the main effects and interactions between pandemic status (i.e. pre vs post March 2020) and quitline offers of free NRT. RESULTS: The COVID-19 pandemic had a persistent negative effect on quitline reach (p=0.002) and impact (p<0.001). Abstinence rates decreased transiently during the first year of the pandemic. Offering free NRT had a positive effect on quitline reach (p<0.001) and impact (p<0.001) before and after the start of the pandemic. For quitline reach, we found a significant interaction between pandemic and free NRT effects with a substantial decrease in the mean number of callers per month after the pandemic during months when free NRT is being offered (750; 95% CI: 545-1033, pre-pandemic vs 302; 95% CI: 233-392, post-pandemic) compared to months when free NRT is not being offered (247; 95% CI: 187-327, pre-pandemic vs 159; 95% CI: 114-221, post-pandemic). CONCLUSIONS: There is a critical need to assess and address the ongoing effects of the COVID-19 pandemic on tobacco quitline reach and impact.","journal":"Tobacco Prevention & Cessation","year":2025,"id":528263,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9148,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1406250,"name":"Karen Brown","orcid":"0000-0002-2686-7871","position":1,"is_corresponding":false},{"id":1031276,"name":"Allison Furgal","orcid":"0000-0001-8081-2444","position":2,"is_corresponding":false},{"id":274073,"name":"Muhammad Arif Nadeem Saqib","orcid":"0000-0001-6365-5520","position":3,"is_corresponding":false},{"id":1406607,"name":"Farid J Shamo","orcid":null,"position":4,"is_corresponding":false},{"id":581602,"name":"Lawrence C.
