Behavioral pain treatments may improve postsurgical analgesia and recovery; however, effective and scalable options are not widely available. This study tested a digital perioperative behavioral medicine intervention in orthopedic trauma surgery patients for feasibility and efficacy for reducing pain intensity, pain catastrophizing, and opioid cessation up to 3 months after surgery.
A randomized controlled clinical trial was conducted at an orthopedic trauma surgery unit at a major academic hospital to compare a digital behavioral pain management intervention ("My Surgical Success" [MSS]) to a digital general health education (HE) intervention (HE; no pain management skills). The enrolled sample included 133 patients; 84 patients were randomized (MSS, n = 37; HE, n = 47) and completed study procedures. Most patients received their assigned intervention within 3 days of surgery (85%). The sample was predominantly male (61.5%), White (61.9%), and partnered (65.5%), with at least a bachelor's degree (69.0%). Outcomes were collected at 1-3 months after intervention through self-report e-surveys and electronic medical record review; an intention-to-treat analytic framework was applied. Feasibility was dually determined by the proportion of patients engaging in their assigned treatment and an application of an 80% threshold for patient-reported acceptability. We hypothesized that MSS would result in greater reductions in pain intensity and pain catastrophizing after surgery and earlier opioid cessation compared to the digital HE control group.
The engagement rate with assigned interventions was 63% and exceeded commonly reported rates for fully automated Internet-based e-health interventions. Feasibility was demonstrated for the MSS engagers, with >80% reporting treatment acceptability. Overall, both groups improved in the postsurgical months across all study variables. A significant interaction effect was found for treatment group over time on pain intensity, such that the MSS group evidenced greater absolute reductions in pain intensity after surgery and up to 3 months later (treatment × time fixed effects; F [215] = 5.23; P = .024). No statistically significant between-group differences were observed for time to opioid cessation or for reductions in pain catastrophizing ( F [215] = 0.20; P = .653), although the study sample notably had subclinical baseline pain catastrophizing scores (M = 14.10; 95% confidence interval, 11.70-16.49).
Study findings revealed that a fully automated behavioral pain management skills intervention (MSS) may be useful for motivated orthopedic trauma surgery patients and reduce postsurgical pain up to 3 months. MSS was not associated with reduced time to opioid cessation compared to the HE control intervention.
行为疼痛治疗可能会改善术后镇痛和康复效果;然而,有效的和可扩展的选择并不广泛。本研究测试了一种数字化围手术期行为医学干预在骨科创伤手术患者中的可行性和疗效,以减轻术后 3 个月内的疼痛强度、疼痛灾难化和阿片类药物停药。
在一家大型学术医院的骨科创伤外科进行了一项随机对照临床试验,比较了数字化行为疼痛管理干预(“我的手术成功”[MSS])与数字化一般健康教育(HE;无疼痛管理技能)干预。纳入的样本包括 133 名患者;84 名患者被随机分组(MSS,n=37;HE,n=47)并完成了研究程序。大多数患者在手术后 3 天内接受了他们的指定干预(85%)。该样本主要为男性(61.5%)、白人(61.9%)和伴侣(65.5%),至少拥有学士学位(69.0%)。通过自我报告的电子调查和电子病历回顾,在干预后 1-3 个月收集结果;采用意向治疗分析框架。可行性通过患者参与其指定治疗的比例和患者报告的可接受性 80%的阈值应用双重确定。我们假设与数字 HE 对照组相比,MSS 将导致术后疼痛强度和疼痛灾难化的更大降低,并更早停止使用阿片类药物。
与指定干预措施相关的参与率为 63%,超过了完全自动化互联网电子健康干预措施的常见报告率。MSS 参与者表现出治疗的可接受性,超过 80%的人报告了治疗的可接受性。总体而言,两组在术后几个月的所有研究变量中均有所改善。治疗组在时间上的交互作用显著影响疼痛强度,例如 MSS 组在手术后和术后 3 个月时疼痛强度的绝对降低更大(治疗×时间固定效应;F[215]=5.23;P=.024)。虽然研究样本的疼痛灾难化评分明显处于亚临床基线水平(M=14.10;95%置信区间,11.70-16.49),但未观察到组间在阿片类药物停药时间或疼痛灾难化减少方面存在统计学上的显著差异(F[215]=0.20;P=.653)。
研究结果表明,完全自动化的行为疼痛管理技能干预(MSS)可能对有动机的骨科创伤手术患者有用,并可在术后长达 3 个月减轻疼痛。与健康教育对照组相比,MSS 与减少阿片类药物停药时间无关。
