Background & Aims

Chronic pain is more widespread and severe among United States military veterans compared to civilians.1 Although guidelines now recommend evidence-based non-pharmacologic treatment approaches for chronic pain (NPTs),2 they are underutilized due to numerous interrelated patient-, provider-, and system-level barriers.3-5 Mindfulness-based interventions (MBIs) are evidence-based NPTs for improving chronic pain and comorbid conditions.6,7 However, many MBIs have features that pose significant implementation barriers for healthcare systems and patients.3-5 This randomized pragmatic trial examined two scalable, telehealth MBIs for Veterans with chronic pain, designed to facilitate participant engagement and reduce system barriers.  Each MBI addressed essential introductory mindfulness knowledge and skills in regulating attention and emotions, establishing body awareness, and shifting self-perceptions, and goals of scalability within the VA healthcare system.3

Methods

Randomized pragmatic trial of 811 men and women veterans with moderate to severe chronic pain, recruited from 3 VA facilities. Two 8-week MBIs, offered in different formats, were compared to Usual Care (UC). Group MBI was delivered via videoconferencing and consisted of pre-recorded mindfulness education and skill training videos by an experienced mindfulness instructor, with discussions by trained facilitators. Self-paced MBI consisted of the same videos, completed asynchronously on one’s own via a mobile app, supplemented by three individual facilitator calls. The primary outcome was pain-related function (Brief Pain Inventory [BPI] interference scale) over 12 months (range, 0-10; higher scores = worse function). Secondary outcomes were pain intensity, global improvement in pain, anxiety, depression, post-traumatic stress disorder (PTSD), physical function, fatigue, sleep disturbance, participation in social roles and activities, and a 30% or more improvement in pain functioning.

Results

Among 811 randomized patients (mean age, 54.6 years; 47.7% women; 62.8% with psychiatric diagnosis), 694 (86%) completed the trial. Over 12 months, the Self-paced MBI group had better pain functioning (mean BPI interference = 4.48) than UC (5.05), difference -0.6 [95% CI, -0.9 to -0.2]); the Group MBI (5.05) and UC did not significantly differ (p = 0.15). Over 12 months, the percentage of participants with 30% or more improvement in BPI interference score was significantly greater in the Self-paced MBI (53.8%) and Group MBI (41.0%) compared to UC (31.7%). The Self-paced MBI had greater improvement on all other secondary outcomes compared to UC; the Group MBI had greater improvements than UC for all other outcomes except anxiety.

Conclusions

Two scalable MBIs, delivered via telehealth, significantly reduced pain interference and other pain and biopsychosocial outcomes when compared to usual care over 12 months, among a veteran population with chronic pain and a high prevalence of psychiatric comorbidity. Although the magnitude of between group effects of the interventions were small, they were consistent across a range of biopsychosocial, whole person outcomes that are important to patients, including improved sleep, fatigue and physical function and reduction in symptoms of anxiety, depression, and PTSD, and persisted over 12 months. This suggests that MBIs are a promising piece of more comprehensive multi-modal interventions that could have larger treatment effects. This study addresses recommendations that more trials of NPTs for pain be conducted on populations that experience health disparities in chronic pain, which includes veterans, those with mental illness and those who are socioeconomically disadvantaged.8
