摘要:
目的 分析美沙酮门诊间转诊后漏服受治者的剂量变化及其影响因素,为加强受治者转诊后服药剂量管理提供依据。 方法 收集广东省9家美沙酮维持治疗门诊自2008年1月~2016年12月所有受治者资料,选择其中未按时返回原门诊的转诊记录进行分析。收集转诊时间、转诊剂量等转诊信息、匹配受治者的服药信息及基本信息,以受治者的转诊后首次服药剂量与转诊期间服药剂量相比剂量是否增加为因变量,运用二水平的Logistic模型分析转诊后剂量增加的影响因素。 结果 本研究共纳入197名受治者合计840人次转诊记录进行分析,其中119(14.26%)人次在转诊后剂量增加,转诊期间美沙酮服药剂量低于60 ml/d(OR=2.88,95%CI:1.85~4.50,P < 0.001),转诊天数越长(OR=1.02,95%CI:1.01~1.03,P < 0.001),累计转诊次数少(OR=0.97,95%CI:0.95~0.99,P=0.004)的受治者越容易在转诊返回后提高美沙酮服用剂量。 结论 部分漏服药的转诊受治者在返回后首次服药会提高其剂量。各美沙酮门诊应加强对转诊受治者尤其是未按时返回的受治者的监管,对于受治者的剂量调整要求慎重考虑,减少剂量变化,提高美沙酮维持治疗的效果。 Abstract:Objective To investigate the effect of transfer service utilization in increased methadone dosage after missed dose of participants in methadone maintenance treatment (MMT). Methods We selected 9 MMT clinics in Guangdong Province and collected the data from the web-based system of MMT management. All the participants who had utilized the transfer service from January 2008 to December 2016 were included in our study. We explored multilevel Logistic regression analysis to explore the associated factors of changing methadone dosage after missed dosage of transfer participants. Results A total of 197 patients were included in the study for a total of 840 person-time transfer services. Of these, 119 (14.26%) had increased-dose after transfer. The patients whose (1) dose of methadone was less than 60 ml/d during the transfer period (OR=2.88, 95%CI: 1.85-4.50, P < 0.001), (2)had longer transfer period (OR=1.02, 95%CI: 1.01-1.03, P < 0.001), and (3) fewer cumulative transfertimes (OR=0.97, 95%CI: 0.95-0.99, P=0.004) were more likely to increase the methadone dosage after the missed. Conclusions The characteristic of transfer service utilization could result in the increasing methadone dosage after missed doses in transfer participants. This finding suggest MMT clinic should strengthen the supervision of transfer patients, especially those who failed to return on time after transfer. The doctors in MMT should carefully consider the dose adjustment requirements from patients and improve the efficacy of methadone maintenance treatment. -
