Our objective was to identify the factors related to returning to smoking by analyzing data obtained from a smoking cessation clinic. Methods We analyzed data from 2,089 subjects (age 44.0 ± 12.9 years) who started a smoking cessation program between 16 J uly 2007 and 31 D ecember 2008 in a community health center in the city of U lsan. We analyzed demographic information and clinical variables using K aplan– M eier survival analysis and calculated the hazard ratio for returning to smoking. Results Mean abstinence time differed according to the following factors: sex, past attempts to quit, employment status, type of health insurance, CO levels, results from F agerstrom test for nicotine dependence ( FTND ), number of cigarettes smoked daily, use of a nicotine replacement, and number of contacts in the program. Using multivariate analysis, we identified negative relationships between treatment intensity and hazard ratio for the following: visits ≤4 ( E xp( B ) = 3.752, P < 0.001, reference: 5 visits ≤), telephone contacts ≤5 ( E xp( B ) = 10.528, P < 0.001, reference: 6 calls ≤) and SMS ≤ 20 ( E xp( B ) = 3.821, P < 0.001 in 0–10 group; E xp( B ) = 1.407, P = 0.003 for the 11–20 group; reference: 21 messages ≤). Discussion Type of insurance, baseline CO , FTND level, and intensity of smoking cessation intervention positively affects outcomes in a smoking cessation clinic. A cost‐effectiveness study on the intensity of interventions in smoking cessation clinics is needed.
