Chronic noncancer pain (CNCP) is a global issue, not only affecting individual suffering, but also impacting the delivery of health care and the strength of local economies.
The current study (the Canadian Chronic Pain Study II [CCPSII]) was designed to assess any changes in the prevalence and treatment of CNCP, as well as in attitudes toward the use of strong analgesics, compared with a 2001 study (the CCPSI), and to provide a snapshot of the current standards of care for pain management in Canada.
Standard, computer-assisted telephone interview survey methodology was applied in two segments, ie, a general population survey and a survey targeting randomly selected primary care physicians (PCPs) who treat moderate to severe CNCP.
The patient-reported prevalence of CNCP within Canada has not markedly changed since 2001 but the duration of suffering has decreased. There have been minor changes in regional distribution and generally more patients receive medical treatment, which includes prescription analgesics. Physicians continue to demonstrate opiophobia in their prescribing practices; however, although this is lessened relating to addiction, abuse remains an important concern to PCPs. Canadian PCPs, in general, are implementing standard assessments, treatment approaches, evaluation of treatment success and tools to prevent abuse and diversion, in accordance with guidelines from the Canadian Pain Society and other pain societies globally, although there remains room for improvement and standardization.
慢性非癌性疼痛（CNCP）是一个全球性问题，不仅影响个人的痛苦感受，还会对医疗保健的提供以及当地经济实力产生影响。
本研究（加拿大慢性疼痛研究II [CCPSII]）旨在评估与2001年的一项研究（CCPSI）相比，CNCP的患病率、治疗情况以及对使用强效镇痛药的态度有何变化，并提供加拿大当前疼痛管理护理标准的概况。
采用标准的计算机辅助电话访谈调查方法，分两个部分进行，即一般人群调查和针对随机选择的治疗中度至重度CNCP的初级保健医生（PCP）的调查。
自2001年以来，加拿大患者报告的CNCP患病率没有明显变化，但痛苦持续时间有所减少。区域分布有轻微变化，总体上更多患者接受了包括处方镇痛药在内的药物治疗。医生在开处方时仍表现出对阿片类药物的恐惧；然而，尽管与成瘾相关的恐惧有所减轻，但滥用仍然是初级保健医生的一个重要担忧。总体而言，加拿大的初级保健医生正在按照加拿大疼痛协会和全球其他疼痛协会的指南，实施标准评估、治疗方法、治疗效果评估以及预防滥用和转移的工具，尽管仍有改进和标准化的空间。
