This study aims to explore whether regular telephone intervention in patients with chronic pancreatitis can improve their smoking cessation rate.
Chronic pancreatitis（CP） is a chronically progressive disease characterized by pancreatic fibrosis and inflammation, and its basic pathological features include chronic inflammatory damage to the pancreatic parenchyma, interstitial fibrosis, pancreatic parenchymal calcification, pancreatic duct dilation, and pancreatic duct stones.
Environmental factors such as alcoholism，smoking and genetic factors are the main causative factors of CP. Clinical studies have found that smoking can not only accelerate the course of CP, but also increase the risk of CP-related complications. Some scholars believe that smoking cessation may be a potential way to prevent the progression of CP and improve the prognosis of CP. Although there is no evidence to verify whether smoking cessation will improve the clinical course of CP, the latest ACG Clinical Guideline strongly recommends CP patients quit smoking.
In 2016，a prospective study of smoking cessation interventions in CP patients showed that 27 enrolled patients had a smoking cessation rate of 0% after 6 months of smoking cessation intervention, indicating that smoking cessation is a huge challenge for CP patients.
The investigators propose to conduct a randomized controlled trial to investigate the effects of telephone intervention on smoking cessation in patients with CP and explore the impact of smoking cessation on their clinical course and prognosis.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention Group | Experimental | Participants in the intervention group will receive one 20-30 minutes "5A" smoking cessation health consultation after enrollment; They will be given regular phone-based smoking cessation intervention once a week in the first month and once a month thereafter (15 times in total). Participants will be followed at 2, 6, 12 months, and cotinine urine test kits will be mailed to those who have self-reported smoking cessation at follow-up, which is used to confirm whether they have quitted smoking or not. (smoking cessation is defined as urine cotinine levels below 200 ng/mL). |
|
| Control Group | No Intervention | Participants in the control group will receive one 20-30 minute "5A" smoking cessation health consultation after enrollment; Phone-based smoking cessation intervention will not be regularly given after enrollment. |
| Name | Type | Description | Arm Group Labels | Other Names |

| Fagerstrom Test of Nicotine Dependence (FTND) scores | The FTND is a validated, 6-item self-report instrument that evaluates the intensity of physical addiction to nicotine. The scores will be assessed at month 2, 6, 12 after quit date.Three items are rated yes/no (0/1), and the other three items are rated on a scale from 0-3. Items are summed to yield a total score of 0-10, with higher scores reflecting greater nicotine dependence. This outcome variable will be reported as the difference in FTND total score between the intervention condition and the control condition. | 12 months |
