ABSTRACT
Objective@#To analyze the factors affecting the dropping-out from methadone maintenance treatment (MMT) in Hangzhou City, so as to provide the evidence for improving the compliance to MMT.@*Methods@#One MMT clinic was sampled from each of the eight districts in Hangzhou City using a cluster random sampling method, and patients that received MMT and were at ages of 18 years and older and registered during the period from December 2020 through June 2021 were recruited. Participants' basic characteristics, illegality and crime within 6 months prior to MMT and family and social relationships were collected through questionnaire surveys, and factors affecting the dropping-out from MMT were identified using a multivariable logistic regression model. @*Results@#A total of 315 outpatients were included from MMT clinics. The participants had a mean age of (45.33±7.63) years, and included 245 men (77.78%) and 70 women (22.22%), with a dropping-out rate of 65.71%. Multivariable logistic regression analysis showed a low likelihood of dropping-out from MMT among patients at ages of 60 years and older (OR=0.080, 95%CI: 0.018-0.350), employees (OR=0.415, 95%CI: 0.236-0.727), patients without drug-related infectious diseases (OR=0.411, 95%CI: 0.231-0.731), patients with per dossing of 60 mL and higher (OR=0.431, 95%CI: 0.236-0.787) and patients without contact with drug-using friends (OR=0.328, 95%CI: 0.185-0.582), and a high possibility of dropping-out from MMT among patients with poor relationship with family members (OR=2.905, 95%CI: 1.127-7.488). @*Conclusion@#Age, working status, drug-related infectious diseases, dosing, relationship with family members and contact with drug-using friends affected the dropping-out from MTT in Hangzhou City.
