There are wide global variations in electroconvulsive therapy (ECT) use patterns. This audit reviewed patient-level ECT use patterns over 10 years at a single New Zealand clinic, including factors associated with clinical response and patterns of repeated administration.
Retrospective audit of all 2003-2012 ECT and clinical file data.
A total of 199 patients received ECT, which was used to treat mostly affective disorders in a predominantly female, older population, generally with a single course of treatment. There were different demographics and patterns of ECT use between patients being treated for affective and psychotic disorders. Overall treatment response was high, with over 90% of patients having a full or partial response. Treatment response was not associated with diagnosis, gender, or medication use, but showed a trend in significance for greater response in elderly patients.
ECT use patterns in Otago New Zealand are similar to those reported in Australia, USA, and UK, although yearly use rate in Otago is lower. Because of their different demographic and ECT treatment patterns, future studies should report data for patients with affective and psychotic disorders separately.
全球范围内电休克治疗（ECT）的使用模式存在广泛差异。本次审计回顾了新西兰一家诊所10年间患者层面的ECT使用模式，包括与临床反应相关的因素以及重复治疗模式。
对2003年至2012年所有ECT及临床档案数据进行回顾性审计。
共有199名患者接受了ECT治疗，主要用于治疗情感障碍，患者群体以女性、老年人为主，通常采用单一疗程治疗。情感障碍和精神障碍患者在人口统计学特征和ECT使用模式上存在差异。总体治疗反应良好，超过90%的患者有完全或部分反应。治疗反应与诊断、性别或药物使用无关，但老年患者反应更大有显著趋势。
新西兰奥塔哥地区的ECT使用模式与澳大利亚、美国和英国报告的模式相似，尽管奥塔哥地区每年的使用率较低。由于情感障碍和精神障碍患者在人口统计学特征和ECT治疗模式上存在差异，未来研究应分别报告这两类患者的数据。
