The management of pain patients with analgesics is challenging, with one of the risks being overdose with prescribed medications and death. In this study, we examined relationships between pain and pain catastrophizing, and past history of intentional overdoses and suicide attempts.
Using a cross-sectional approach and a self-report survey methodology, we examined 239 consecutive internal medicine outpatients in the United States. We inquired about pain "today, over the past month," and "over the past year;" and assessed pain catastrophizing with the Pain Catastrophizing Scale (PCS), past histories of intentional overdoses, and suicide attempts.
There were statistically significant relationships between all of the pain variables, as well as PCS scores, and history of intentional overdoses. There were also statistically significant relationships between all of the pain variables, as well as PCS scores, and history of suicide attempts.
Although we cannot discern causal relationships, findings indicate that patients with pain complaints and pain catastrophizing have a greater likelihood of having past histories of intentional overdoses and suicide attempts. We discuss the potential implications of these findings.
疼痛患者的镇痛管理具有挑战性，其中一个风险是过量服用处方药物和死亡。在这项研究中，我们研究了疼痛与疼痛灾难化之间的关系，以及过去故意服药过量和自杀企图的历史。
我们使用横断面方法和自我报告调查方法，检查了美国 239 名连续的内科门诊患者。我们询问了“今天”、“过去一个月”和“过去一年”的疼痛情况；并使用疼痛灾难化量表（PCS）评估了疼痛灾难化、故意服药过量和自杀企图的过去史。
所有疼痛变量以及 PCS 评分与故意服药过量的历史之间存在统计学显著关系。所有疼痛变量以及 PCS 评分与自杀企图的历史之间也存在统计学显著关系。
尽管我们无法辨别因果关系，但研究结果表明，有疼痛投诉和疼痛灾难化的患者更有可能有过去故意服药过量和自杀企图的历史。我们讨论了这些发现的潜在影响。
