Use of chronic opioid therapy has increased substantially over the past few years, even though opioid therapy is associated with potentially serious harms, including opioid-related adverse effects and outcomes. Prescription of opioids for chronic pain, particularly nonmalignant chronic pain, remains controversial. In the midst of this controversy, patterns of actual prescription and influences on these patterns are not well understood. This study aims to describe the frequency of prescription of opioid analgesics in a university hospital, the attitudes of doctors towards this category of drugs, and the follow-up modalities of patients taking these drugs. The study also explores the association between the practitioners' characteristics and the modalities of prescription.
A survey was delivered to 112 doctors and surgeons in the hospital during the four months between August and December 2013 and it was returned by 55 (49.0%). The survey consists of three parts. The first part addresses the frequency and reluctance of doctors' prescription of opioids and other analgesics for acute and chronic pain. The second part studies the doctors' attitudes and concerns towards opioids. It explores the belief of the doctors in the efficacy of this category of drugs, their confidence in prescribing such medications and the eventual side effects they might worry about. The third part of the survey studies the modalities of evaluation prior to the prescription and the modalities of follow-up of the patients receiving a long-term opioid treatment.
Overall, 76.4% of doctors reported they sometimes, frequently, or always, prescribe opioids, which, using the Wilcoxon test, proved to be a significantly lower frequency than for prescribing of minor analgesics or nonsteroidal anti-inflammatory drugs (NSAIDS). Similarly, 60.1% reported a reluctance to prescribe opioids for chronic nonmalignant pain, which was a significantly greater reluctance than for cancer pain. The age and sex of the participants were unrelated to prescribing, but those with specialty training and use of practice guidelines were more likely to prescribe opioids and were less reluctant to do so. A majority of practitioners felt that opioids are effective for the treatment of chronic nonmalignant pain and that they have the sufficient training to prescribe them adequately; however, they still worry about the long-term prescription of opioids, particularly fearing the psychological dependence this treatment might cause. Using a series of Spearman correlation tests, we found that practitioners who thought they were adequately trained and who believed in the efficacy of long-term opioid treatment were more likely to prescribe them but that the worries about side effects decreased the frequency of prescription. A significant proportion of practitioners do not evaluate addiction risk factors of patients before prescribing opioids. The results concerning the modalities of follow-up of prescription were very heterogeneous with 87% of practitioners not explaining and 65% not screening for adverse effects. We similarly found that the frequency of follow-up and the management of patients who were exhibiting signs of dependence were very diverse.
The results of this study were compatible with those of other recent studies about opioid prescription. The doctors practicing in the university hospital Hôtel-Dieu de France de Beyrouth present comparable prescription patterns, independent of their personal or professional characteristics, and they are more confident in their prescription when professionally trained for it. However, they exhibit a notable heterogeneity in their attitudes towards opioids and in their modalities of evaluating patients receiving long-term treatment. These results suggest a need for additional training in the management of this category of drugs.
在过去几年中,慢性阿片类药物治疗的使用显著增加,尽管阿片类药物治疗与潜在的严重危害相关,包括阿片类药物相关的不良反应和后果。阿片类药物用于慢性疼痛,尤其是非恶性慢性疼痛的处方仍然存在争议。在这场争议中,实际处方模式及其影响因素尚未得到很好的理解。本研究旨在描述大学医院中阿片类镇痛药的处方频率、医生对这类药物的态度以及服用这些药物患者的随访方式。该研究还探讨了从业者特征与处方方式之间的关联。
2013年8月至12月的四个月期间,向医院的112名医生和外科医生发放了一份调查问卷,55人(49.0%)回复。该调查问卷由三部分组成。第一部分涉及医生对急性和慢性疼痛开具阿片类药物及其他镇痛药的频率和顾虑。第二部分研究医生对阿片类药物的态度和担忧。探讨医生对这类药物疗效的看法、他们开具此类药物的信心以及他们可能担心的最终副作用。调查问卷的第三部分研究处方前的评估方式以及接受长期阿片类药物治疗患者的随访方式。
总体而言,76.4%的医生报告他们有时、经常或总是开具阿片类药物,经威尔科克森检验,这一频率显著低于开具轻度镇痛药或非甾体抗炎药(NSAIDs)的频率。同样,60.1%的医生报告不愿为慢性非恶性疼痛开具阿片类药物,这一顾虑明显高于癌症疼痛。参与者的年龄和性别与处方情况无关,但接受过专业培训且使用实践指南的人更有可能开具阿片类药物,且不太不愿意这样做。大多数从业者认为阿片类药物对治疗慢性非恶性疼痛有效,并且他们有足够的培训来合理开具此类药物;然而,他们仍然担心阿片类药物的长期处方,尤其担心这种治疗可能导致的心理依赖。通过一系列斯皮尔曼相关性检验,我们发现认为自己接受了充分培训且相信长期阿片类药物治疗疗效的从业者更有可能开具此类药物,但对副作用的担忧会降低处方频率。很大一部分从业者在开具阿片类药物之前未评估患者的成瘾风险因素。关于处方随访方式的结果差异很大,87%的从业者未进行解释,65%的从业者未筛查不良反应。同样,我们发现随访频率以及对出现依赖迹象患者的管理方式也多种多样。
本研究结果与近期其他关于阿片类药物处方的研究结果一致。在贝鲁特法国主宫医院工作的医生呈现出类似的处方模式,与他们的个人或专业特征无关,并且当接受过专业培训时,他们对处方更有信心。然而,他们在对阿片类药物的态度以及对接受长期治疗患者的评估方式上表现出显著的异质性。这些结果表明需要在这类药物的管理方面进行额外培训。
