Acceptance and Commitment Therapy for Prevention of Chronic Postsurgical Pain and Opioid Use in At-Risk Veterans: A Pilot Randomized Controlled Study

Acceptance and commitment therapy for patients with chronic pain: A systematic review and meta-analysis on psychological outcomes and quality of life

OBJECTIVES

To assess the efficacy of acceptance and commitment therapy (ACT) for patients with chronic pain.

MATERIALS AND METHODS

The research conducted a systematic search of the Cochrane Library, Web of Science, PubMed, EMBASE, PsycINFO, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) databases following the PRISMA guidelines. The retrieval time limit was from the establishment of the database to October 2023. A meta-analysis was carried out for the randomized controlled trials (RCTs) that meet the inclusion and exclusion criteria by using RevMan 5.3.

RESULTS

Twenty-one RCTs were included. At post-treatment, a significant medium effect size (ES) was found in measuring pain interference, functional impairment, pain acceptance, psychological inflexibility, and depression; Pain intensity, anxiety, and quality of life (QOL) had a small ES. At three months post-treatment, a large ES was found in measuring functional impairment, and a medium ES was found in the other indicators.

CONCLUSION

The researchers provided evidence for the effectiveness of ACT as an intervention for patients with chronic pain, which can be applied by clinicians or nurses in practice. Future research should explore the applicability of ACT to different pain conditions and modalities.

IMPLICATIONS FOR NURSING

Post-treatment data highlight the efficacy of ACT in moderating pain-related outcomes. Clinical nurses are encouraged to incorporate ACT into routine patient education and interventions, including promoting pain acceptance, promoting mindfulness practices, and using cognitive stress reduction techniques. Standardized follow-up after an ACT intervention for patients with chronic pain is critical, including regular assessment, feedback, and realignment of treatment strategies. Overall, ACT became an important tool for nurses to improve the lives of patients with chronic pain.

Demystifying the virtualization process: A call for standard reporting of virtual modifications to evidence-based psychotherapies, using the FRAME model

The sudden onset of the coronavirus disease led to a rapid expansion of video telehealth to deliver mental healthcare. Although video telehealth was not a new clinical practice, there was limited guidance on how best to modify evidence-based psychotherapies (EBPs) for virtual delivery (a process also referred to as virtualization). The virtualization process for EBPs remains unclear as newly emerging reports on this topic do not consistently report modification decisions. This commentary calls attention to the need to improve documentation practices to allow a greater understanding of modifications needed to maximize the positive effects of EBPs transported to a virtual format. We used the Framework for Reporting Adaptations and Modifications-Expanded (FRAME) to capture details about the nature, process, and outcomes of intervention modifications across a given clinical setting or population. To illustrate the use of the FRAME, we present a case example describing our experiences with transporting a 1-day in-person Acceptance and Commitment Therapy group workshop to a virtual format. Workshop modifications primarily involved changes to the delivery format, administration procedures, and content. The case example walks through how, why, and by whom specific modifications were made as well as the degree to which fidelity was maintained. In the wake of the telemedicine revolution, further investigation into the virtualization process for EBPs is warranted. Improving reporting practices by using the FRAME or a similar adaptation framework will promote a more rigorous study of virtual modifications to EBPs that inform future guidelines and best practices.

Mindfulness-Based Interventions for Perioperative Pain Management and Opioid Risk Reduction Following Surgery: A Stepped Care Approach

Surgical procedures often improve health and function but can sometimes also result in iatrogenic effects, including chronic pain and opioid misuse. Due to the known risks of opioids and the physical, emotional, and financial suffering that often accompanies chronic pain, there has been a call for greater use of complementary non-pharmacological treatments like mindfulness-based interventions. Mindfulness can be broadly described as an attentional state involving moment-by-moment meta-awareness of thoughts, emotions, and body sensations. An expanding number of randomized clinical trials have found strong evidence for the value of mindfulness techniques in alleviating clinical symptomology relevant to surgical contexts. The purpose of this review is to examine the empirical evidence for the perioperative use of mindfulness interventions. We present a mindfulness-based stepped care approach that first involves brief mindfulness to treat preoperative pain and anxiety and prevent development of postoperative chronic pain or opioid misuse. More extensive mindfulness-based interventions are then provided to patients who continue to experience high pain levels or prolonged opioid use after surgery. Finally, we review psychophysiological mechanisms of action that may be integral to the analgesic and opioid sparing effects of mindfulness.

A Single-Session Process-Based Cognitive-Behavioral Intervention Combined with Multimodal Rehabilitation Treatment for Chronic Pain Associated with Emotional Disorders

BACKGROUND AND OBJECTIVES

Defined by chronic pain, rheumatic diseases are often co-occurring with anxiety and depression. Among the available psychological interventions, cognitive-behavioral therapies have an already-proven efficiency in these cases. However, the need to adjust their structure became ubiquitous during the post-pandemic period. Hence, the objective of this study was to investigate the impact of a single-session, process-based cognitive-behavioral intervention for patients with rheumatic conditions within an in-patient setting.

MATERIALS AND METHODS

A total of 31 participants (mean age 58.9 years) completed the single-session intervention. Assessments were conducted prior to the intervention, post-intervention and after one month.

RESULTS

Pearson's correlations, paired samples T tests and a covariance analysis based on the Linear Mixed Model were performed for exploring the relations between baseline variables and evaluating the impact of the SSI intervention. Immediately after the intervention, a significant reduction in cognitive fusion (p = 0.001, d = 1.78), experiential avoidance (p = 0.001, d = 1.4) and dysfunctional behavioral processes was observed. At the one-month evaluation, participants reported decreased pain (p = 0.001, d = 1.11), anxiety (p = 0.004, d = 0.55) and depression (p = 0.001, d = 0.72).

CONCLUSIONS

The single-session, process-based approach represents a promising intervention in healthcare contexts, as an integrative part of a multimodal rehabilitation treatment in patients with rheumatic conditions.

Benefits, Recruitment, Dropout, and Acceptability of the Strength Back Digital Health Intervention for Patients Undergoing Spinal Surgery: Nonrandomized, Qualitative, and Quantitative Pilot Feasibility Study

BACKGROUND

Patients undergoing spinal surgery report high levels of insecurity, pain, stress, and anxiety before and after surgery. Unfortunately, there is no guarantee that surgery will resolve all issues; postsurgical recovery often entails moderate to severe postoperative pain, and some patients undergoing spinal surgery do not experience (long-term) pain relief after surgery. Therefore, focusing on sustainable coping skills and resilience is crucial for these patients. A digital health intervention based on acceptance and commitment therapy (ACT) and positive psychology (PP) was developed to enhance psychological flexibility and well-being and reduce postsurgical pain.

OBJECTIVE

The objective of this study was 3-fold: to explore the potential benefits for patients undergoing spinal surgery of the digital ACT and PP intervention Strength Back (research question [RQ] 1), explore the feasibility of a future randomized controlled trial in terms of recruitment and dropout (RQ 2), and assess the acceptability of Strength Back by patients undergoing spinal surgery (RQ 3).

METHODS

We used a nonrandomized experimental design with an intervention group (n=17) and a control group (n=20). To explore the potential benefits of the intervention, participants in both groups filled out questionnaires before and after surgery. These questionnaires included measurements of pain intensity (Numeric Pain Rating Scale), pain interference (Multidimensional Pain Inventory), anxiety and depression (Hospital Anxiety and Depression Scale), valued living (Engaged Living Scale), psychological flexibility (Psychological Inflexibility in Pain Scale), and mental well-being (Mental Health Continuum-Short Form). Semistructured interviews combined with log data and scores on the Twente Engagement With eHealth Technologies Scale were used to assess the acceptability of the intervention.

RESULTS

A significant improvement over time in emotional (V=99; P=.03) and overall (V=55; P=.004) well-being (Mental Health Continuum-Short Form) was observed only in the intervention group. In addition, the intervention group showed a significantly larger decline in pain intensity (Numeric Pain Rating Scale) than did the control group (U=75; P=.003). Of the available weekly modules on average 80% (12/15) was completed by patients undergoing spinal fusion and 67% (6/9) was completed by patients undergoing decompression surgery. A total of 68% (17/25) of the participants used the intervention until the final interview. Most participants (15/17, 88%) in the intervention group would recommend the intervention to future patients.

CONCLUSIONS

This pilot feasibility study showed that combining ACT and PP in a digital health intervention is promising for patients undergoing spinal surgery as the content was accepted by most of the participants and (larger) improvements in pain intensity and well-being were observed in the intervention group. A digital intervention for patients undergoing (spinal) surgery can use teachable moments, when patients are open to learning more about the surgery and rehabilitation afterward. A larger randomized controlled trial is now warranted.

What are the benefits of cultivating self-compassion in adults with low back pain? A systematic review

Introduction

Low back pain is one of the most prevalent public health problems in the world, generating psychosocial impacts on quality of life and a high demand for medical care. Self-compassion may be beneficial for low back pain control, however, studies in the area are scarce. Therefore, this systematic review aimed to investigate the benefits of self-compassion-related interventions on low back pain and mental health in adults.

Methods

The review protocol was registered in PROSPERO and the method was performed according to the PRISMA guidelines. Searches were conducted using the keywords "self-compassion" and "low back pain" in Portuguese, English, and Spanish in the following databases: PubMed, LILACS, SciELO, PePSIC, PsycInfo, Embase, Scopus, Web of Science, and Cochrane. Additional searches were also conducted through the references of the included studies.

Results

Thirty-three articles were identified and analyzed by two independent reviewers using Rayyan. Four of these studies were included. RoB 2 was used to assess the risk of bias of each study. The main findings suggest that self-compassion-related interventions demonstrate benefits in the treatment of low back pain, as well as reduction in pain intensity, psychological stress, and improvement of pain acceptance.

Discussion

However, these positive data must be analyzed carefully, as only two studies presented a low risk of bias. Despite growing interest in this field, more research self-compassion-related interventions for low back pain are suggested, since biopsychosocial aspects associated with low back pain can impact the outcome of treatment.

An individualised tapering protocol reduces opioid use 1 year after spine surgery: A randomised controlled trial of patients with preoperative opioid use

BACKGROUND

Persistent opioid use following surgery is common especially in patients with preoperative opioid use. This study aims to determine the long-term effect of an individualised opioid tapering plan versus standard of care in patients with a preoperative opioid use undergoing spine surgery at Aarhus University Hospital, Denmark.

METHODS

This is the 1-year follow-up of a prospective, single-centre, randomised trial of 110 patients who underwent elective spine surgery for degenerative disease. The intervention was an individualised tapering plan at discharge and telephone counselling 1 week after discharge, compared to standard of care. Postoperative outcomes after 1 year include opioid use, reasons for opioid use and pain intensity.

RESULTS

The overall response rate to the 1-year follow-up questionnaire was 94% (intervention group 52/55 patients and control group 51/55 patients). Forty-two patients (proportion = 0.81, 95% CI 0.67-0.89) in the intervention group compared to 31 (0.61, 95% CI 0.47-0.73; p = .026) patients in the control group succeeded in tapering to zero 1 year after discharge (p = .026). One patient (0.02, 95% CI 0.01-0.13) in the intervention group compared to seven patients (0.14, 95% CI 0.07-0.26) in the control group were unable to taper to their preoperative dose 1 year after discharge (p = .025). Back/neck and radicular pain intensity was similar between study groups.

CONCLUSION

These results suggest that an individualised tapering plan at discharge combined with telephone counselling 1 week after discharge can reduce opioid use 1 year after spine surgery.

Predicting chronic postsurgical pain: current evidence and a novel program to develop predictive biomarker signatures

ABSTRACT

Chronic pain affects more than 50 million Americans. Treatments remain inadequate, in large part, because the pathophysiological mechanisms underlying the development of chronic pain remain poorly understood. Pain biomarkers could potentially identify and measure biological pathways and phenotypical expressions that are altered by pain, provide insight into biological treatment targets, and help identify at-risk patients who might benefit from early intervention. Biomarkers are used to diagnose, track, and treat other diseases, but no validated clinical biomarkers exist yet for chronic pain. To address this problem, the National Institutes of Health Common Fund launched the Acute to Chronic Pain Signatures (A2CPS) program to evaluate candidate biomarkers, develop them into biosignatures, and discover novel biomarkers for chronification of pain after surgery. This article discusses candidate biomarkers identified by A2CPS for evaluation, including genomic, proteomic, metabolomic, lipidomic, neuroimaging, psychophysical, psychological, and behavioral measures. Acute to Chronic Pain Signatures will provide the most comprehensive investigation of biomarkers for the transition to chronic postsurgical pain undertaken to date. Data and analytic resources generatedby A2CPS will be shared with the scientific community in hopes that other investigators will extract valuable insights beyond A2CPS's initial findings. This article will review the identified biomarkers and rationale for including them, the current state of the science on biomarkers of the transition from acute to chronic pain, gaps in the literature, and how A2CPS will address these gaps.

Feasibility of delivering a virtual 1-day acceptance and commitment therapy workshop to rural veterans through community partnerships

Background

This single-arm, open pilot study examined the feasibility and initial efficacy of a 1-day virtual Acceptance and Commitment Therapy (ACT) group workshop for distressed veterans.

Methods

We collaborated with veteran-serving community-based organizations to enhance outreach to veterans, especially those in rural areas. Veterans completed a baseline assessment and two follow-up assessments (1 month, 3 months) after workshop participation. Feasibility outcomes included reach (workshop recruitment and completion rates; veteran characteristics) and acceptability (open-ended survey question about satisfaction). Clinical outcomes included psychological distress (Outcome Questionnaire-45), stressor-related distress (PTSD Checklist-5), community reintegration (Military to Civilian Questionnaire), and meaning and purpose (PROMIS Short Form). Psychological flexibility (Action and Acceptance Questionnaire-II) - the proposed change mechanism underlying ACT - was also measured.

Results

Sixty-four veterans (50% rural, 39% self-identified as female) participated in a virtual workshop (97.1% completion rate). Overall, veterans liked the format and interactive nature of workshops. Convenience was noted as a benefit, while connectivity issues were highlighted as a drawback. Veterans showed improvements in psychological distress (F(2,109) = 3.30; p = 0.041), stressor-related distress (F(2,110) = 9.50; p = 0.0002), community reintegration (F(2,108) = 4.34; p = 0.015), and meaning and purpose (F(2,100) = 4.06; p = 0.020) over time. No between-group differences were detected, based on rurality or gender.

Conclusion

Pilot findings were promising and warrant a larger randomized trial to assess the efficacy of the 1-day virtual ACT workshop. Integrating community-engaged and participatory-research designs can enhance the external validity of these future studies and promote greater health equity.

A Conceptual Model for Spine Surgery Recovery: A Qualitative Study of Patients' Expectations, Experiences, and Satisfaction

STUDY DESIGN

Qualitative interview study.

OBJECTIVE

The aim was to develop a conceptual model for Spine Surgery Recovery in order to better understand why patients undergo lumbar spine surgery and what factors influence patient satisfaction.

SUMMARY OF BACKGROUND DATA

Quantitative studies have assessed patients' expectations for lumbar spine surgery outcomes, with greater expectation fulfillment leading to higher satisfaction. However, there is limited literature using qualitative methods to understand the patient perspective from the decision to undergo lumbar spine surgery through long-term recovery.

MATERIALS AND METHODS

Semistructured phone interviews were conducted with 20 participants (nine females, mean age ±SD=61.2±11.1 yr) and three focus groups with 12 participants (nine females, mean age ±SD=62.0±10.9 yr). Sessions were audio recorded and transcribed. Two independent researchers coded the transcripts using a hierarchical coding system. Major themes were identified and a conceptual model was developed.

RESULTS

A total of 1355 coded quotes were analyzed. The decision to have lumbar spine surgery was influenced by chronic pain impact on daily function, pain coping, and patient expectations. Results demonstrated that fulfilled expectations and setting realistic expectations are key factors for patient satisfaction after surgery, while less known constructs of accepting limitations, adjusting expectations, and optimism were found by many patients to be essential for a successful recovery. Emotional factors of fear, anxiety, and depression were important aspects of presurgical and postsurgical experiences.

CONCLUSION

Our Spine Surgery Recovery conceptual model provides guidance for future research and clinical practice to optimize treatment and improve overall patient satisfaction. Recommendations based on this model include the assessment of patient expectations and mental well-being throughout postoperative recovery as well as preoperatively to help set realistic expectations and improve satisfaction. Educational, acceptance-based or positive psychological interventions may be potentially beneficial for addressing key factors identified in this model.

Military Veterans' Perspectives on Postoperative Opioid Use: A Secondary Analysis of Qualitative Data

PURPOSE

This qualitative analysis of interviews with surgical patients who received a brief perioperative psychological intervention, in conjunction with standard medical perioperative care, elucidates patient perspectives on the use of pain self-management skills in relation to postoperative analgesics.

DESIGN

This study is a secondary analysis of qualitative data from a randomized controlled trial.

METHODS

Participants (N = 21) were rural-dwelling United States Military Veterans from a mixed surgical sample who were randomized to receive a manual-based, telephone-based Perioperative Pain Self-management intervention consisting of a total of four pre- and postoperative contacts. Semi-structured qualitative interviews elicited participant feedback on the cognitive-behavioral intervention. Data was analyzed by two qualitative experts using MAXQDA software. Key word analyses focused on mention of analgesics in interviews.

FINDINGS

Interviews revealed a dominant theme of ambivalence towards postoperative use of opioids. An additional theme concerned the varied ways acquiring pain self-management skills impacted postoperative opioid (and non-opioid analgesic) consumption. Participants reported that employment of pain self-management strategies reduced reliance on pharmacology for pain relief, prolonged the time between doses, took the "edge off" pain, and increased pain management self-efficacy.

CONCLUSIONS

Perioperative patient education may benefit from inclusion of teaching non-pharmacologic pain self-management skills and collaborative planning with patients regarding how to use these skills in conjunction with opioid and non-opioid analgesics. Perianesthesia nurses may be in a critical position to provide interdisciplinary postoperative patient education that may optimize postoperative pain management while minimizing risks associated with prolonged opioid use.

Brief Mindfulness-Based Cognitive Behavioral Therapy is Associated with Faster Recovery in Patients Undergoing Total Knee Arthroplasty: A Pilot Clinical Trial

OBJECTIVE

To assess whether brief mindfulness-based cognitive behavioral therapy (MBCBT) could enhance the benefits of total knee arthroplasty (TKA) in improving pain and pain-related disability. Specifically, to determine 1) whether patients who received MBCBT differed from matched controls who received treatment-as-usual with regard to postsurgical pain outcomes and 2) whether changes in pain catastrophizing, depression, or anxiety explained the potential effects of MBCBT on pain outcomes.

DESIGN

Pilot clinical trial.

SETTING

An academic teaching hospital serving a large urban and suburban catchment area surrounding the Boston, Massachusetts metropolitan region.

SUBJECTS

Sample of 44 patients undergoing TKA. Patients who completed a brief MBCBT intervention (n = 22) were compared with age-, race-, and sex-matched controls who received treatment-as-usual (n = 22).

METHODS

The MBCBT intervention included four 60-minute sessions delivered by a pain psychologist in person and via telephone during the perioperative period. Participants were assessed at baseline and at 6 weeks, 3 months, and 6 months after surgery.

RESULTS

Compared with matched controls, patients who received MBCBT had lower pain severity and pain interference at 6 weeks after surgery. Group differences in outcomes were mediated by changes in pain catastrophizing but not by changes in depression or anxiety. The MBCBT group had similar reductions in pain severity and interference as the control group did at 3 and 6 months after surgery.

CONCLUSIONS

This work offers evidence for a safe and flexibly delivered nonpharmacological treatment (MBCBT) to promote faster recovery from TKA and identifies change in pain catastrophizing as a mechanism by which this intervention could lead to enhanced pain-related outcomes.

Mobile Acceptance and Commitment Therapy With Distressed First-Generation College Students: Microrandomized Trial

BACKGROUND

Extant gaps in mental health services are intensified among first-generation college students. Improving access to empirically based interventions is critical, and mobile health (mHealth) interventions are growing in support. Acceptance and commitment therapy (ACT) is an empirically supported intervention that has been applied to college students, via mobile app, and in brief intervals.

OBJECTIVE

This study evaluated the safety, feasibility, and effectiveness of an ACT-based mHealth intervention using a microrandomized trial (MRT) design.

METHODS

Participants (N=34) were 18- to 19-year-old first-generation college students reporting distress, who participated in a 6-week intervention period of twice-daily assessments and randomization to intervention. Participants logged symptoms, moods, and behaviors on the mobile app Lorevimo. After the assessment, participants were randomized to an ACT-based intervention or no intervention. Analyses examined proximal change after randomization using a weighted and centered least squares approach. Outcomes included values-based and avoidance behavior, as well as depressive symptoms and perceived stress.

RESULTS

The findings indicated the intervention was safe and feasible. The intervention increased values-based behavior but did not decrease avoidance behavior. The intervention reduced depressive symptoms but not perceived stress.

CONCLUSIONS

An MRT of an mHealth ACT-based intervention among distressed first-generation college students suggests that a larger MRT is warranted. Future investigations may tailor interventions to contexts where intervention is most impactful.

Can perioperative psychological interventions reduce chronic pain after surgery?

Chronic post-surgical pain is a relatively common adverse effect following surgery. Several prognostic factors for chronic post-surgical pain have been identified, including psychological states and traits. Psychological factors are modifiable, and perioperative psychological interventions may reduce the incidence of chronic post-surgical pain. A meta-analysis showed preliminary evidence for the benefits of such interventions for the prevention of chronic post-surgical pain. Further research must be conducted to better understand the specific type, intensity, duration and timing of interventions that are most effective. The number of studies in this area has recently increased, with additional randomised controlled trials currently being carried out, which may allow for the development of more robust conclusions in the coming years. In order to implement perioperative psychological care alongside routine surgical interventions, efficient and accessible interventions should be available. In addition, demonstration of cost-effectiveness may be a prerequisite for wider adoption of perioperative psychological interventions in regular healthcare. Offering psychological interventions selectively to patients at risk of chronic post-surgical pain could be a means to increase cost-effectiveness. Stepped-care approaches should also be considered, where the intensity of psychological support is adapted to the needs of the patient.

Association Between Preoperative Multidimensional Psychological Distress and Physical Function After Surgery for Sports-Related Injury

Background

Psychological distress after orthopaedic surgery can lead to worse outcomes, including higher levels of disability and pain and lower quality of life. The 10-item Optimal Screening for Prediction for Referral and Outcome-Yellow Flag (OSPRO-YF) survey screens for multiple psychological constructs relevant to recovery from orthopaedic injury and may be useful to preoperatively identify patients who may require further psychological assessment and possible intervention after surgery.

Purpose/Hypothesis

To determine the association between the OSPRO-YF and physiological patient-reported outcomes (PROs). It was hypothesized that higher OSPRO-YF scores (indicating worse psychological distress) would be associated with worse PRO scores at time of return to sport.

Study Design

Case series; Level of evidence, 4.

Methods

This study evaluated 107 patients at a single, academic health center who were assessed at a sports orthopaedics clinic and ultimately treated surgically for injuries to the knee, shoulder, foot, or ankle. Preoperatively, patients completed the OSPRO-YF survey as well as the following PRO measures: Patient-Reported Outcomes Measurement Information System (PROMIS), Single Assessment Numeric Evaluation, numeric rating scale for pain; American Shoulder and Elbow Surgeons standardized shoulder assessment form for patients with shoulder injuries, the International Knee Documentation Committee score (for patients with knee injuries), and the Foot and Ankle Ability Measure (FAAM; for patients with foot or ankle injuries). At the time of anticipated full recovery and/or return to sport, patients again completed the same PRO surveys. Multivariable regression was used to evaluate the association between total OSPRO-YF score at baseline and PRO scores at the time of functional recovery.

Results

The baseline OSPRO-YF score predicted postoperative PROMIS Physical Function and FAAM Sports scores only. A 1-unit increase in the OSPRO-YF was associated with a 0.55-point reduction in PROMIS Physical Function (95% CI, -1.05 to -0.04; P = .033) indicating worse outcomes. Among patients who underwent ankle surgery, a 1-unit increase in OSPRO-YF was associated with a 6.45-point reduction in FAAM Sports (95% CI, -12.0 to -0.87; P = .023).

Conclusion

The study findings demonstrated that the OSPRO-YF survey predicts certain long-term PRO scores at the time of expected return to sport, independent of baseline scores.

Let’s Get Physical! A Comprehensive Review of Pre- and Post-Surgical Interventions Targeting Physical Activity to Improve Pain and Functional Outcomes in Spine Surgery Patients

The goal of this comprehensive review was to synthesize the recent literature on the efficacy of perioperative interventions targeting physical activity to improve pain and functional outcomes in spine surgery patients. Overall, research in this area does not yet permit definitive conclusions. Some evidence suggests that post-surgical interventions may yield more robust long-term outcomes than preoperative interventions, including large effect sizes for disability reduction, although there are no studies directly comparing these surgical approaches. Integrated treatment approaches that include psychosocial intervention components may supplement exercise programs by addressing fear avoidance behaviors that interfere with engagement in activity, thereby maximizing the short- and long-term benefits of exercise. Efforts should be made to test brief, efficient programs that maximize accessibility for surgical patients. Future work in this area should include both subjective and objective indices of physical activity as well as investigating both acute postoperative outcomes and long-term outcomes.

Higher Pain Catastrophizing and Preoperative Pain is Associated with Increased Risk for Prolonged Postoperative Opioid Use

BACKGROUND

Prolonged postoperative opioid use (PPOU) is considered an unfavorable post-surgical outcome. Demographic, clinical, and psychosocial factors have been associated with PPOU, but methods to prospectively identify patients at increased risk are lacking.

OBJECTIVES

Our objective was to determine whether an individual or a combination of several psychological factors could identify a subset of patients at increased risk for PPOU.

STUDY DESIGN

Observational cohort study with prospective baseline data collection and passive outcomes data collection.

SETTING

A single VA medical center in the United States.

METHODS

Patients were recruited from a preoperative anesthesia clinic where they were undergoing evaluation prior to elective surgery, and they completed a survey before surgery. The primary outcome was PPOU, defined as outpatient receipt of a prescribed opioid 31 to 90 days after surgery as determined from pharmacy records. Primary covariates of interest were pain catastrophizing, self-efficacy, and optimism. Additional covariates included social and demographic factors, pain severity, medication use, depression, anxiety, and surgical fear.

RESULTS

Of 123 patients included in the final analyses, 30 (24.4%) had PPOU. In bivariate analyses, preoperative opioid use and preoperative nonsteroidal anti-inflammatory drug use were significantly associated with PPOU. The combination of high pain catastrophizing and high preoperative pain (OR 3.32, 95% CI 1.41 - 7.79) was associated with higher odds of PPOU than either alone, and the association remained significant after adjusting for preoperative opioid use (OR 2.56, 95% CI 1.04 - 6.29).

LIMITATIONS

Patients were recruited from a single site, and the sample was not large enough to include potentially important variables such as procedure type.

CONCLUSIONS

A combination of high pain catastrophizing and high preoperative pain has the potential to be a clinically useful means of identifying patients at elevated risk of PPOU.

A longitudinal assessment of posttraumatic stress symptoms and pain catastrophizing after injury

PURPOSE/OBJECTIVE

Identifying individuals with high levels of pain catastrophizing (PC) may inform early psychological interventions to prevent the transition from acute to chronic post-injury pain. We examined whether pre-and post-injury posttraumatic stress symptoms (PTSS) predict post-injury PC among emergency department (ED) patients following acute motor vehicle crash (MVC).

RESEARCH METHOD/DESIGN

This study represents secondary data analysis of a randomized clinical trial (NCT03247179) examining the efficacy of the PTSD Coach app on post-injury PTSS (PTSSpost). Among 63 injured ED patients (63% female; 57% non-White; average age = 37) with moderate pain (≥4 of 10), we assessed recall of pre-injury PTSS (PTSSrecall: stemming from preexisting exposures) and baseline PC within 24 hr post-MVC; PTSSpost stemming from the MVC was assessed 30-days later, and the outcome of PC was assessed at 90-days post-injury. We controlled for group assignment (intervention vs. control) in all analyses.

RESULTS

Results revealed that at baseline and 90-days, PC was higher among non-White versus White participants. After adjusting for relevant covariates, PTSSrecall uniquely predicted post-injury PC and each subscale of PC (helplessness, magnification, and rumination). Similarly, after controlling for PTSSrecall and relevant covariates, PTSSpost uniquely predicted total and subscale post-injury PC. Intervention group participants reported less rumination than control group participants.

CONCLUSIONS/IMPLICATIONS

These novel findings highlight that injured Black patients may be vulnerable to post-injury PC, and that both PTSSrecall and PTSSpost significantly predict post-injury PC. Brief PTSS assessment in the ED can identify high-risk patients who may benefit from early intervention. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Chronic pain acceptance: Relations to opioid misuse and pain management motives among individuals with chronic low back pain

The opioid epidemic is a significant public health concern, and opioid consumption rates and opioid-related deaths are on the rise. Chronic pain acceptance, or willingness to experience pain and pain-related distress, is one pain-related psychological mechanism that may reduce maladaptive attempts to avoid or control pain using opioids among individuals with chronic lower back pain (CLBP). However, little work has examined chronic pain acceptance as it relates to opioid use and motives for use among adults with CLBP. The current investigation sought to explore the effects of chronic pain acceptance on opioid misuse and motives for opioid use (i.e., pain management and coping motives) among adults with CLBP. Participants were 291 adults (69.1 % female, Mage = 45.77 years, SD = 11.22) self-reporting current mild to severe CLBP and current opioid use who were recruited via an online survey. Results indicated that higher acceptance of pain was related to lower levels of opioid misuse and lower motivation to use opioids to cope with pain. Contrary to hypotheses, chronic pain acceptance did not predict motivation to use opioids to cope with emotional distress (i.e., coping motives). The current findings provide support for chronic pain acceptance as a potential protective mechanism in terms of opioid misuse and motivation to use opioids to manage pain.

Peri-OPerative Pain Management, Education & De-escalation (POPPMED), a novel anaesthesiologist-led program, significantly reduces acute and long-term postoperative opioid requirements: a retrospective cohort study

Supplemental Digital Content is Available in the Text.

Perioperative pain management, education, and de-escalation, a single anaesthesiologist-led perioperative service, managed older, high-risk opioid-tolerant patients to achieve sustained oral morphine equivalent daily dosage reductions safely after major orthopaedic, abdominal, and neurosurgery.

Introduction:

The opioid tolerant patient requiring surgery is highly likely to be discharged on high Oral Morphine Equivalent Daily Dosages (OMEDDs), with concomitant risk of increased morbidity and mortality.

Objectives:

We proposed that a single anaesthesiologist-led POPPMED (Peri-Operative Pain Management, Education & De-escalation) service could reduce both short and long-term postoperative patient OMEDDs.

Methods:

From April 2017, our anaesthesiologist-led POPPMED service, engaged 102 perioperative patients treated with >50mg preoperative OMEDDs. We utilized behavioural interventions; acute opioid reduction and/ or rotation; and regional, multimodal and ketamine analgesia to achieve lowest possible hospital discharge and long term OMEDDs.

Results:

Patients' preoperative OMEDDs were [median (IQR): 115mg (114mg)], and were representative of an older [age 62 (15) years], high-risk [89% ASA status 3 or 4] patient population. 46% of patients received an acute opioid rotation; 70% received ketamine infusions; and 44% regional analgesia. OMEDDs on discharge [-25mg (82mg), p=0.003] and at 6-12 months [-55mg (105mg ), p<0.0001] were significantly reduced; 84% and 87% of patients achieved OMEDD reduction on discharge and at 6-12 months. Patients with >90mg preoperative OMEDDs achieved greater reductions [discharge: 71% of patients, -52 mg (118 mg) p<0.0001; 6-12 months: 90% of patients, -90mg (115mg), p<0.0001]. On comparison with a pre-POPPMED surgical cohort, Postoperative Day 1-3 11-point Numerical Rating Scale (NRS-11) area under the curve (AUC) measurements at rest and on movement were not significantly different (largest NRS-11:hours AUC difference [median(IQR)] 22 [13], p= 0.24). Hospital length of stay was variably increased.

Conclusions:

POPPMED achieved sustained OMEDD reductions safely in an older, high-risk opioid tolerant population, with analgesia comparable to a non-POPPMED cohort, and surgery specific effects on length of stay.

Can perioperative psychological interventions decrease the risk of postsurgical pain and disability? A systematic review and meta-analysis of randomized controlled trials

ABSTRACT

Many patients experience pain after surgery. Psychological factors such as emotion and cognition are shown to be associated with the development of acute and chronic postsurgical pain (CPSP). Therefore, the question arises whether targeting these psychological factors can reduce negative postsurgical outcomes. The aim of the current review was to investigate the efficacy of perioperative psychological interventions in reducing (sub)acute postsurgical pain and CPSP and disability in adults. Randomized controlled trials were identified through 4 databases (Web of Science, PsychINFO, PubMed, and Cumulative Index to Nursing and Allied Health Literature [CINAHL]). The outcomes of interest were (sub)acute (ie, within 3 months after surgery) and chronic (>3 months after surgery) pain and disability. After screening, 21 studies were included in the final analyses. It was found that psychological interventions significantly reduced (sub)acute pain (d = -0.26, 95% confidence interval [CI] [-0.48 to -0.04]) and disability (d = -0.43, 95% CI [-0.84 to -0.03]) as well as CPSP (d = -0.33, 95% CI [-0.61 to -0.06]) and disability (d = -0.43, 95% CI [-0.68 to -0.18]). In addition, interventions delivered after surgery and interventions delivered by a psychologist tended to be more effective than interventions delivered before surgery and interventions delivered by another healthcare provider. Furthermore, the current review points to the need for more research to determine which specific type of intervention may be most beneficial for surgical patients. Finally, the current review identified that research in this domain has concerns regarding bias in missing outcome data due to withdrawal and drop out.

Targeting Affective Mood Disorders With Ketamine to Prevent Chronic Postsurgical Pain

The phencyclidine-derivative ketamine [2-(2-chlorophenyl)-2-(methylamino)cyclohexan-1-one] was added to the World Health Organization's Model List of Essential Medicines in 1985 and is also on the Model List of Essential Medicines for Children due to its efficacy and safety as an intravenous anesthetic. In sub-anesthetic doses, ketamine is an effective analgesic for the treatment of acute pain (such as may occur in the perioperative setting). Additionally, ketamine may have efficacy in relieving some forms of chronic pain. In 2019, Janssen Pharmaceuticals received regulatory-approval in both the United States and Europe for use of the S-enantiomer of ketamine in adults living with treatment-resistant major depressive disorder. Pre-existing anxiety/depression and the severity of postoperative pain are risk factors for development of chronic postsurgical pain. An important question is whether short-term administration of ketamine can prevent the conversion of acute postsurgical pain to chronic postsurgical pain. Here, we have reviewed ketamine's effects on the biopsychological processes underlying pain perception and affective mood disorders, focusing on non-NMDA receptor-mediated effects, with an emphasis on results from human trials where available.

Perioperative Opioid Counseling Reduces Opioid Use Following Primary Total Joint Arthroplasty

BACKGROUND

Preoperative counseling may reduce postoperative opioid requirements; however, there is a paucity of randomized controlled trials (RCTs) demonstrating efficacy. The purpose of this study was to perform an interventional, telehealth-based RCT evaluating the effect of peri-operative counseling on quantity and duration of opioid consumption following primary total joint arthroplasty (TJA).

METHODS

Participants were randomized into three groups: 1. Control group, no perioperative counseling; 2. Intervention group, preoperative educational video; 3. Intervention group, preoperative educational video and postoperative acceptance and commitment therapy (ACT). Opioid consumption was evaluated daily for 14 days and at 6 weeks postoperatively. Best-case and worse-case intention to treat analyses were performed to account for non-responses. Bonferroni corrections were applied.

RESULTS

183 participants were analyzed (63 in Group 1, 55 in Group 2, and 65 in Group 3). At 2 weeks postoperatively, there was no difference in opioid consumption between Groups 1, 2, and 3 (p>0.05 for all). At 6 weeks postoperatively, Groups 2 and 3 had consumed significantly less opioids than Group 1 (p=0.04, p<0.001) (Table 1). Group 3 participants were less likely to obtain an opioid refill relative to Group 1 participants (p=0.04). Participants in groups 2 and 3 ceased opioid consumption a median of 6 days and 2 days sooner than Group 1, respectively (p<0.001, p=0.03) (Table 2).

CONCLUSION

Perioperative opioid counseling significantly decreases the quantity and duration of opioid consumption at 6 weeks following primary TJA. Level of Evidence: I.

A Multidisciplinary Transitional Pain Management Program Is Associated With Reduced Opioid Dependence After Primary Total Joint Arthroplasty

BACKGROUND

Overprescription of opioids after total joint arthroplasty (TJA) increases risks of opioid dependence, overdose, and death. The authors hypothesized that a multidisciplinary, perioperative pain management program (the Transitional Pain Service or TPS) for TJA would lead to fewer patients becoming opioid dependent.

METHODS

A TPS was implemented at a Veterans Affairs Medical Center focused on nonopioid pain management, cessation support, and prospective data tracking. A historical control, interventional study design was used to assess opioid use at 90 days post-discharge. Secondary analysis of the implementation group included post-operative outcome scores, time to opioid cessation, and median opioid tablets consumed at 90 days.

RESULTS

Fewer patients in the TPS group demonstrated persistent opioid use at 90 days post-discharge (0.7% vs 9.9%; P = .004). Independent predictors of total opioid tablet prescriptions included TPS (β = -19.41; 95% confidence interval [CI] -35.37 to -3.47), number of tablets prescribed at discharge (β = 1.08; 95% CI 0.86-1.31), and TKA surgery (β = 16.84; 95% CI 4.58-29.10). Under the TPS, median tablets consumed was 20.5 for THA and 36.5 for TKA; median time to cessation was shorter in THA (7 days; 95% CI 2-10) when compared to TKA (13 days; 95% CI 11-16).

CONCLUSION

In opioid-naïve veterans undergoing TJA, the TPS was associated with a 93% reduction in opioid dependence and a 60% reduction in opioid tablet prescriptions at 90 days post-discharge. Under the TPS, median 90-day opioid consumption was 20.5 and 36.5 tablets for THA and TKA, respectively. Widespread adoption of similar programs may greatly reduce opioid use and dependence in orthopedic patients nationally.

Strategies aimed at preventing long-term opioid use in trauma and orthopaedic surgery: a scoping review

Background

Long-term opioid use, which may have significant individual and societal impacts, has been documented in up to 20% of patients after trauma or orthopaedic surgery. The objectives of this scoping review were to systematically map the research on strategies aiming to prevent chronic opioid use in these populations and to identify knowledge gaps in this area.

Methods

This scoping review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Checklist. We searched seven databases and websites of relevant organizations. Selected studies and guidelines were published between January 2008 and September 2021. Preventive strategies were categorized as: system-based, pharmacological, educational, multimodal, and others. We summarized findings using measures of central tendency and frequency along with p-values. We also reported the level of evidence and the strength of recommendations presented in clinical guidelines.

Results

A total of 391 studies met the inclusion criteria after initial screening from which 66 studies and 20 guidelines were selected. Studies mainly focused on orthopaedic surgery (62,1%), trauma (30.3%) and spine surgery (7.6%). Among system-based strategies, hospital-based individualized opioid tapering protocols, and regulation initiatives limiting the prescription of opioids were associated with statistically significant decreases in morphine equivalent doses (MEDs) at 1 to 3 months following trauma and orthopaedic surgery. Among pharmacological strategies, only the use of non-steroidal anti-inflammatory drugs and beta blockers led to a significant reduction in MEDs up to 12 months after orthopaedic surgery. Most studies on educational strategies, multimodal strategies and psychological strategies were associated with significant reductions in MEDs beyond 1 month. The majority of recommendations from clinical practice guidelines were of low level of evidence.

Conclusions

This scoping review advances knowledge on existing strategies to prevent long-term opioid use in trauma and orthopaedic surgery patients. We observed that system-based, educational, multimodal and psychological strategies are the most promising. Future research should focus on determining which strategies should be implemented particularly in trauma patients at high risk for long-term use, testing those that can promote a judicious prescription of opioids while preventing an illicit use, and evaluating their effects on relevant patient-reported and social outcomes.

Chronic Pain in the Elderly: Mechanisms and Perspectives

Chronic pain affects a large part of the population causing functional disability, being often associated with coexisting psychological disorders, such as depression and anxiety, besides cognitive deficits, and sleep disturbance. The world elderly population has been growing over the last decades and the negative consequences of chronic pain for these individuals represent a current clinical challenge. The main painful complaints in the elderly are related to neurodegenerative and musculoskeletal conditions, peripheral vascular diseases, arthritis, and osteoarthritis, contributing toward poorly life quality, social isolation, impaired physical activity, and dependence to carry out daily activities. Organ dysfunction and other existing diseases can significantly affect the perception and responses to chronic pain in this group. It has been proposed that elderly people have an altered pain experience, with changes in pain processing mechanisms, which might be associated with the degeneration of circuits that modulate the descending inhibitory pathways of pain. Aging has also been linked to an increase in the pain threshold, a decline of painful sensations, and a decrease in pain tolerance. Still, elderly patients with chronic pain show an increased risk for dementia and cognitive impairment. The present review article is aimed to provide the state-of-art of pre-clinical and clinical research about chronic pain in elderly, emphasizing the altered mechanisms, comorbidities, challenges, and potential therapeutic alternatives.

Preventing Pediatric Chronic Postsurgical Pain: Time for Increased Rigor

Chronic postsurgical pain (CPSP) results from a cascade of events in the peripheral and central nervous systems following surgery. Several clinical predictors, including the prior pain state, premorbid psychological state (e.g., anxiety, catastrophizing), intraoperative surgical load (establishment of peripheral and central sensitization), and acute postoperative pain management, may contribute to the patient’s risk of developing CPSP. However, research on the neurobiological and biobehavioral mechanisms contributing to pediatric CPSP and effective preemptive/treatment strategies are still lacking. Here we evaluate the perisurgical process by identifying key problems and propose potential solutions for the pre-, intra-, and postoperative pain states to both prevent and manage the transition of acute to chronic pain. We propose an eight-step process involving preemptive and preventative analgesia, behavioral interventions, and the use of biomarkers (brain-based, inflammatory, or genetic) to facilitate timely evaluation and treatment of premorbid psychological factors, ongoing surgical pain, and postoperative pain to provide an overall improved outcome. By achieving this, we can begin to establish personalized precision medicine for children and adolescents presenting to surgery and subsequent treatment selection.

Factors affecting sufentanil consumption for intravenous controlled analgesia after hepatectomy: retrospective analysis

Background

Pain control after hepatectomy is usually achieved by opioids. There are significant individual differences in the amount of opioids used after hepatectomy, and the metabolism of opioids is liver-dependent. The purpose of our study was to explore the possible risk factors for opioid consumption during the first 48 h after surgery.

Methods

In a retrospective study design involving 562 patients undergoing open or laparoscopic hepatectomy, all patients were treated with intravenous patient-controlled analgesia (IV-PCA) along with continuous and bolus doses of sufentanil for a duration of 48 h after surgery during the time period of August 2015 and February 2019. The primary endpoint was high sufentanil consumption 48 h after hepatectomy, and patients were divided into two groups: those with or without a high PCA sufentanil dosage depending on the third quartile (Q3). The secondary endpoint was the effect of a high PCA sufentanil dosage on various possible clinical risk factors. The relevant parameters were collected, and correlation and multivariate regression analyses were performed.

Results

The median operation time was 185 min (range, 115–250 min), and the median consumption of sufentanil 48 h after the operation was 91 μg (IQR, 64.00, 133.00). Factors related to the consumption of sufentanil at 48 h after hepatectomy included age, operation time, blood loss, intraoperative infusion (red blood cells and fresh-frozen plasma), pain during movement after surgery (day 1 and day 2), preoperative albumin, and postoperative blood urea nitrogen. Age (≤ 60 and > 60 years), extent of resection (minor hepatic resection and major hepatic resection), surgical approach (laparoscope and open) and operation time (min) were independent risk factors for sufentanil consumption at 48 h postoperatively.

Conclusion

Age younger than 60 years, major hepatic resection, an open approach and a longer operation are factors more likely to cause patients to require higher doses of sufentanil after hepatectomy, and the early identification of such patients can increase the efficacy of perioperative pain management.

Risk and Resilience Predictors of Recovery After Spinal Fusion Surgery in Adolescents

OBJECTIVE

This prospective study examined risk and resilience predictors of pain and functional recovery in the first 6 months after spinal fusion surgery in adolescents.

METHODS

Adolescents with adolescent idiopathic scoliosis undergoing spinal fusion surgery (n=100, aged 12 to 18 y, 77% girls) completed assessments before surgery and at 3 weeks, 6 weeks, and 6 months after surgery. Recovery trajectories in pain, health-related quality of life (HRQOL), and objectively registered physical activity were identified. Presurgical pain catastrophizing and pain intensity (risk), and psychological flexibility, and postsurgical pain acceptance (resilience) were examined as predictors of recovery.

RESULTS

Latent growth class analyses revealed 4 distinct pain recovery trajectories (ie, Severe-Moderate [11%, n=9], Mild-No [58%, n=49], Moderate-Mild [24%, n=20], and Moderate-Severe [7%, n=6] pain trajectory), 2 HRQOL recovery trajectories; 2 trajectories characterizing recovery in average daily physical activity at moderate-to-vigorous intensity (MVPA); and 3 trajectories characterizing recovery in total physical activity volume characterized by the average daily number of steps. Subsequent multivariate analyses of variance revealed that presurgical pain intensity (partial η2=0.21, P<0.001) and pain catastrophizing (partial η2=0.13, P<0.01) were both predictive of poorer recovery in HRQOL, and pain catastrophizing additionally predicted poorer pain recovery (partial η2=0.15, P<0.05). Psychological flexibility (partial η2=0.25, P<0.001) and postsurgical pain acceptance (partial η2=0.07, P<0.05) were predictive of more favorable recovery trajectories in HRQOL, and psychological flexibility additionally predicted more favorable recovery trajectories in postsurgical pain (partial η2=0.15, P<0.05). Daily MVPA trajectories were not significantly predicted by any of the hypothesized factors, while presurgical pain catastrophizing levels were predictive of a delayed recovery trajectory in the daily amount of steps (partial η2=0.17 P<0.01).

CONCLUSIONS

Presurgical screening could include assessment of pain intensity, pain catastrophizing, psychological flexibility, and pain acceptance to identify adolescents who are at risk for poorer recovery. These are potentially modifiable factors that can be targeted in presurgical interventions to prevent poor and foster adaptive outcomes after major surgery in adolescents.

Patient-reported opioid analgesic use after discharge from surgical procedures: a systematic review

OBJECTIVE

This systematic review synthesizes evidence on patient-reported outpatient opioid analgesic use post-surgery.

METHODS

We searched Pubmed (February 2019), Web of Science and Embase (June 2019) for U.S. studies describing patient-reported outpatient opioid analgesic use. Two reviewers extracted data on opioid analgesic use, standardized use, and performed independent quality appraisals based on the Cochrane Risk of Bias Tool and an adapted Newcastle-Ottawa scale.

RESULTS

Ninety-six studies met eligibility criteria; 56 had sufficient information to standardize use in oxycodone 5 mg tablets. Patient-reported opioid analgesic use varied widely by procedure type; knee and hip arthroplasty had the highest postoperative opioid use, and use after many procedures was reported as < 5 tablets. In studies that examined excess tablets, 25%-98% of the total tablets prescribed were reported to be excess, with most studies reporting that 50%-70% of tablets went unused. Factors commonly associated with higher opioid analgesic use included preoperative opioid analgesic use, higher inpatient opioid analgesic use, higher postoperative pain scores, and chronic medical conditions, among others. Estimates also varied across studies due to heterogeneity in study design, including length of follow-up and inclusion/exclusion criteria.

CONCLUSION

Self-reported post-surgery outpatient opioid analgesic use varies widely both across procedures and within a given procedure type. Contributors to within-procedure variation included patient characteristics, prior opioid use, intraoperative and perioperative factors, and differences in timing of opioid use data collection. We provide recommendations to help minimize variation caused by study design factors and maximize interpretability of forthcoming studies for use in clinical guidelines and decision-making.

Chronic Pain, Opioid Use Disorder, and Clinical Management Among Older Adults

Because of unique factors related to physiological changes and altered metabolism in advanced age, special attention is needed concerning chronic pain, opioid use, and opioid use disorder among older adults. Clinicians need to follow the most updated clinical guidelines regarding opioid prescribing. Routine screening and awareness are the keys to identifying opioid use disorder. Comprehensive assessments often require both pain assessment (including functional status) and substance use assessment, including the use of urine toxicological testing and structured, validated screening tools and instruments. Comprehensive, interdisciplinary efforts are critical in managing the care of older adults with chronic pain and opioid use disorder. A collaborative approach that includes substance abuse treatment and pain management (including pain subspecialty care) is often recommended. Medications for opioid use disorder have been extensively studied and have the most convincing evidence to date, and psychosocial treatments may be beneficial in some circumstances.

To be mindful of the breath or pain: Comparing two brief preoperative mindfulness techniques for total joint arthroplasty patients

OBJECTIVE

Total joint arthroplasty (TJA) often reduces pain and improves function, but it is also a risk factor for the development of chronic pain and postoperative opioid use. To protect against these untoward postsurgical outcomes, TJA patients need better, non-pharmacological pain management strategies. This study compared two, promising, mindfulness-based pain management techniques.

METHOD

We conducted a single-site, three-arm, parallel-group randomized controlled study conducted at an orthopedic clinic among patients undergoing TJA of the knee or hip. TJA patients (N = 118, M age = 65, female = 73, Caucasian = 110) were randomized to either a preoperative mindfulness of breath (MoB), mindfulness of pain (MoP), or cognitive-behavioral pain psychoeducation (CB) intervention, approximately 3 weeks before surgery. Each intervention was delivered in a single, 20-min session during a 2-hr, preoperative education program. Change in pain intensity was the sole preoperative outcome. The postoperative outcomes, pain intensity, pain interference, and opioid use were assessed on the 2nd, 3rd, 7th, 14th, 21st, and 28th postoperative days.

RESULTS

MoB was found to most effectively decrease preoperative pain scores, F(2, 89) = 5.28, p = .007, while MoP resulted in the least amount of postoperative pain intensity, F(8, 94) = 3.21, p = .003, and interference, F(8, 94) = 2.52, p = .016). Both MoB and MoP decreased postoperative opioid use relative to CB, F(8, 83) = 16.66, p < .001.

CONCLUSION

A brief preoperative MBI may be able to prevent both postoperative pain and opioid use. Moreover, the MBIs used in this study are highly feasible, capable of being delivered by nearly any healthcare provider, and requiring minimal clinic time given their brevity. As such, embedding MBIs in surgical care pathways has considerable potential. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Acceptance and commitment therapy for high frequency episodic migraine without aura: Findings from a randomized pilot investigation

OBJECTIVE

We compared the incremental effects of adding acceptance and commitment therapy (ACT) to pharmacological treatment as usual (TAU) in a sample of patients with high frequency episodic migraine without aura (HFEM), assessing impact on a spectrum of measures across multiple domains.

BACKGROUND

Patients with HFEM are at risk of developing chronic migraine and medication overuse headache. ACT has been shown to be effective for the treatment of various chronic pain conditions, but little attention has been given to its therapeutic value in the management of recurring headaches.

METHODS

In this single-blind (masking for outcome assessor), open-label, randomized clinical trial, 35 patients with HFEM, with a monthly headache frequency ranging from 9 to 14 days, were recruited at the headache center of C. Besta Neurological Institute and randomized to either TAU (patient education and pharmacological prophylaxis; n = 17) or TAU + ACT (n = 18). Patients assigned to the combined treatment arm additionally received six 90-min weekly group sessions of ACT therapy and two supplementary "booster" sessions. All patients were on a stable course of prophylactic medication in the 3 months prior to initiating either treatment. Monthly headache frequency served as the primary outcome measure, with all other data collected being considered as secondary measures (medication intake, disability, headache impact, anxiety and depression, catastrophizing, allodynia, cognitive inflexibility, pain acceptance, mindful attention and awareness).

RESULTS

A total of 35 patients were enrolled: 17 randomized to TAU, of whom three dropped out, and 18 to TAU + ACT (no dropouts in this group). Headache frequency and medication intake decreased in both groups over 12 months, with patients in the TAU + ACT group showing statistically significant reduction earlier, that is, by month 3. Headache frequency was reduced by 3.3 days (95% CI: 1.4 to 5.2) among those randomized to ACT + TAU, whereas it increased by 0.7 days (95% CI: -2.7 to 1.3) among those randomized to TAU only (p = 0.007, partial η²  = 0.21), the difference being 4 days (95% CI: 1.2 to 6.8). Medication intake was reduced by 4.1 intakes (95% CI: 2.0 to 6.3) among those randomized to ACT + TAU and by 0.4 intakes (95% CI: -1.8 to 2.5) among those randomized to TAU only (p = 0.016; partial η²  = 0.17), the difference being 3.8 intakes (95% CI: 0.7 to 6.8). At 6 and 12 months, the variations were not different between the two groups for headache frequency and medication intake. The opposite was found for measures of headache impact and pain acceptance, where the differences over time favored patients allocated to TAU. Both groups improved with regard to measures of disability, anxiety and depression, catastrophizing, and cognitive inflexibility, whereas measures of allodynia and pain acceptance were stable over time.

CONCLUSIONS

Our preliminary findings indicate that supplementing TAU with ACT can enhance the main clinical outcomes, namely headache frequency and medication intake of patients with HFEM.

Brief preoperative mind-body therapies for total joint arthroplasty patients: a randomized controlled trial

ABSTRACT

Although knee and hip replacements are intended to relieve pain and improve function, up to 44% of knee replacement patients and 27% of hip replacement patients report persistent postoperative joint pain. Improving surgical pain management is essential. We conducted a single-site, 3-arm, parallel-group randomized clinical trial conducted at an orthopedic clinic, among patients undergoing total joint arthroplasty (TJA) of the hip or knee. Mindfulness meditation (MM), hypnotic suggestion (HS), and cognitive-behavioral pain psychoeducation (cognitive-behavioral pain psychoeducation) were each delivered in a single, 15-minute group session as part of a 2-hour, preoperative education program. Preoperative outcomes-pain intensity, pain unpleasantness, pain medication desire, and anxiety-were measured with numeric rating scales. Postoperative physical functioning at 6-week follow-up was assessed with the Patient-Reported Outcomes Measurement Information System Physical Function computer adaptive test. Total joint arthroplasty patients were randomized to preoperative MM, HS, or cognitive-behavioral pain psychoeducation (n = 285). Mindfulness meditation and HS led to significantly less preoperative pain intensity, pain unpleasantness, and anxiety. Mindfulness meditation also decreased preoperative pain medication desire relative to cognitive-behavioral pain psychoeducation and increased postoperative physical functioning at 6-week follow-up relative to HS and cognitive-behavioral pain psychoeducation. Moderation analysis revealed the surgery type did not differentially impact the 3 interventions. Thus, a single session of a simple, scripted MM intervention may be able to immediately decrease TJA patients' preoperative clinical symptomology and improve postoperative physical function. As such, embedding brief MM interventions in surgical care pathways has the potential to improve surgical outcomes for the millions of patients receiving TJA each year.

Predictors of Persistent Postsurgical Pain After Hysterectomy-A Prospective Cohort Study

STUDY OBJECTIVE

To determine sociodemographic, surgical, and psychologic risk factors, including pain sensitivity, for persistent postsurgical pain (PPSP) after hysterectomy.

DESIGN

A prospective cohort study.

SETTING

Canadian academic medical center.

PATIENTS

Patients (N = 200) who underwent hysterectomy (vaginal, laparoscopic, robotic, or open) between 2013 and 2014.

INTERVENTIONS

Participants completed preoperative questionnaires assessing baseline pain scores and psychologic factors, including the Pain Sensitivity Questionnaire, Brief Pain Inventory Interference Items, the Beck Depression Inventory, the Numeric Rating Scale (NRS), and the Pain Catastrophizing Scale. Pain was recorded 1 and 24 hours postoperatively using the NRS. Patients were reassessed at 6 weeks postoperatively and completed the Brief Pain Inventory Interference Items, Patient Global Impression of Change, and the NRS. Patients who reported pain at 6 weeks were reassessed at 12 weeks using the above-mentioned questionnaires.

MEASUREMENTS AND MAIN RESULTS

Of 200 study participants, 58 (32%) met the definition for PPSP (NRS ≥ 1 at 12 weeks), and 11 (6.1%) met the definition for moderate to severe postsurgical pain (NRS ≥ 4 at 12 weeks). Risk factors for PPSP included baseline pain scores, depression, pain catastrophizing, uterine mass, open surgical approach, acute postoperative pain, history of chronic pain, and having a hysterectomy due to pain. Multivariate regression analysis revealed that depression, pain catastrophizing, open surgical approach, and acute postoperative pain at 1 hour represent independent predictors of PPSP. Pain sensitivity was not associated with PPSP but was associated with acute and severe acute (NRS≥4) pain at 24 hours.

CONCLUSION

Patients at risk for PPSP after hysterectomy can be identified preoperatively using validated questionnaires. This information can be used to guide targeted perioperative interventions to mitigate their risk.

Psychological interventions to reduce postoperative pain and opioid consumption: a narrative review of literature

BACKGROUND

Evidence suggests that over half of patients undergoing surgical procedures suffer from poorly controlled postoperative pain. In the context of an opioid epidemic, novel strategies for ameliorating postoperative pain and reducing opioid consumption are essential. Psychological interventions defined as strategies targeted towards reducing stress, anxiety, negative emotions and depression via education, therapy, behavioral modification and relaxation techniques are an emerging approach towards these endpoints.

OBJECTIVE

This review explores the efficacy of psychological interventions for reducing postoperative pain and opioid use in the acute postoperative period.

EVIDENCE REVIEW

An extensive literature search was conducted in MEDLINE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Medline In-Process/ePubs, Embase, Ovid Emcare Nursing, and PsycINFO, Web of Science (Clarivate), PubMed-NOT-Medline (NLM), CINAHL and ERIC, and two trials registries, ClinicalTrials.Gov (NIH) and WHO ICTRP. Included studies were limited to those investigating adult human subjects, and those published in English.

FINDINGS

Three distinct forms of psychological interventions were identified: relaxation, psychoeducation and behavioral modification therapy. Study results showed a reduction in both postoperative opioid use and pain scores (n=5), reduction in postoperative opioid use (n=3), reduction in postoperative pain (n=5), no significant reduction in pain or opioid use (n=7), increase in postoperative opioid use (n=1) and an increase in postoperative pain (n=1).

CONCLUSION

Some preoperative psychological interventions can reduce pain scores and opioid consumption in the acute postoperative period; however, there is a clear need to strengthen the evidence for these interventions. The optimal technique, strategies, timing and interface requires further investigation.

Item Response Theory Analysis: PROMIS® Anxiety Form and Generalized Anxiety Disorder Scale

Little research has compared item functioning of the Patient-Reported Outcomes Measurement Information System (PROMIS^®) anxiety short form 6a and the generalized anxiety disorder 7-item scale using item response theory models. This was a secondary analysis of self-reported assessments from 67 at-risk U.S. military veterans. The two measures performed comparably well with data fitting adequately to models, acceptable item discriminations, and item and test information curves being unimodal and symmetric. The PROMIS^® anxiety short form 6a performed better in that item difficulty estimates had a wider range and distributed more evenly and all response categories had less floor effect, while the third category in most items of the generalized anxiety disorder 7-item scale were rarely used. While both measures may be appropriate, findings provided preliminary information supporting use of the PROMIS^® anxiety short form 6a as potentially preferable, especially for veterans with low-to-moderate anxiety. Further testing is needed in larger, more diverse samples.

Cognition in the Chronic Pain Experience: Preclinical Insights

Acutely, pain is protective. It promotes escape from, and future avoidance of, noxious stimuli through strong and often lifetime associative memories. However, with persistent acute pain or when pain becomes chronic, these memories can promote negative emotions and poor decisions often associated with deleterious behaviors. In this review, we discuss how preclinical studies can provide insights into the relationship between cognition and chronic pain. We also discuss the concept of pain as a cognitive disorder and new strategies for treating chronic pain that emphasize inhibiting the formation of pain memories or promoting 'forgetting' of established pain memories.

The Effect of Psychological Interventions on the Prevention of Chronic Pain in Adults: A Systematic Review and Meta-analysis

OBJECTIVE

Up to 50% of patients develop high-impact chronic pain after an acute care experience and many psychological variables have been identified in this process. We conducted a systematic review and meta-analysis of randomized controlled trials to assess the effect of psychological interventions within 3 months after pain onset.

METHODS

We searched databases for articles published from databases inceptions until July 2019. We used standardized mean differences with 95% confidence intervals to assess treatment effect.

RESULTS

In all, 18 trials were found eligible; 11 of which were included in the meta-analyses. Trials were mainly performed in back pain patients in the middle to late adulthood. Regarding pain intensity, the effect of psychological interventions compared with standard treatments was nonsignificant at 3, 6, and 12 months. We found a moderate significant effect size in favor of psychological interventions compared with standard treatments with regard to disability at 12 months and a small significant effect with regard to coping with pain at 3 months when compared with information alone. Most of meta-analysis findings were associated with a low level of evidence.

DISCUSSION

This systematic review and meta-analysis showed no significant effect of psychological interventions on pain intensity. A positive and significant trend related to these interventions was shown on disability and coping with pain, when compared with standard treatment and information, respectively. However, these findings must be interpreted with caution considering the limited sample of trials. More rigorous randomized controlled trials performed in patients with a high-risk psychological profile are required to elucidate the efficacy of psychological interventions in preventing chronic pain.

Single-Session Acceptance and Commitment Therapy (ACT) Interventions for Patients with Chronic Health Conditions: A Systematic Review and Meta-Analysis

RATIONALE

Chronic health conditions (CHCs) are costly and difficult to manage. Patients often struggle with behavioral adherence to complex treatment regimens and experience psychiatric distress. Acceptance and Commitment Therapy (ACT) is a transdiagnostic behavioral approach that aims to improve functioning and quality of life (QoL), which are important treatment outcomes for this population. Preliminary efficacy of multi-session ACT in patients with CHCs has been demonstrated, and single-session ACT interventions have since been developed to increase feasibility, acceptability, and accessibility. The purpose of this systematic review and meta-analysis was to describe the literature on single-session ACT intervention studies in CHC populations with regards to (1) study design and methodology, (2) patient characteristics and conditions targeted, and (3) efficacy for outcomes across various domains, using narrative and quantitative methods.

METHODS

PsycINFO, PubMed, and Web of Science were systematically searched in August 2020. Studies of single-session ACT interventions in adult patients with CHCs that reported quantitative outcomes in any of the following domains were included: (a) functioning and related domains (e.g., disability, QoL, well-being); (b) mental health; (c) physical health; (d) ACT processes. Both controlled and uncontrolled studies were included. Study quality was assessed using the Psychotherapy Outcome Study Methodology Rating Scale (POMRF). Between-group random effects meta-analysis was conducted on general functioning outcomes.

RESULTS

Fourteen manuscripts reporting outcomes from 13 studies (N = 793) met inclusion criteria. Ten studies were identified by their authors as pilot or feasibility trials. Eight studies used comparison or control groups. Twelve studies delivered the ACT content in workshop format. Studies recruited for a variety of conditions. Narrative review found that between- and within-group effect sizes showed generally positive results favoring single-session ACT overall (69%), especially for measures of functioning and related domains (88%), mental health (67%), and ACT processes (73%). Meta-analysis found that ACT did not significantly outperform comparison groups on measures of general functioning (Hedges' g: -0.51, 95% confidence interval: [-1.19, 0.16]; I 2 = 86%; K = 5) despite a medium-sized pooled effect.

DISCUSSION

Use of single-session ACT interventions in CHC populations is an emergent field. There is preliminary evidence for the acceptability, feasibility, and efficacy of these interventions, which provides support for further testing in fully-powered RCTs. Additional RCTs will enable larger meta-analyses and stronger conclusions about efficacy. Recommendations for future trials are provided.

Perioperative Pain Management and Opioid Stewardship: A Practical Guide

Surgical procedures are key drivers of pain development and opioid utilization globally. Various organizations have generated guidance on postoperative pain management, enhanced recovery strategies, multimodal analgesic and anesthetic techniques, and postoperative opioid prescribing. Still, comprehensive integration of these recommendations into standard practice at the institutional level remains elusive, and persistent postoperative pain and opioid use pose significant societal burdens. The multitude of guidance publications, many different healthcare providers involved in executing them, evolution of surgical technique, and complexities of perioperative care transitions all represent challenges to process improvement. This review seeks to summarize and integrate key recommendations into a "roadmap" for institutional adoption of perioperative analgesic and opioid optimization strategies. We present a brief review of applicable statistics and definitions as impetus for prioritizing both analgesia and opioid exposure in surgical quality improvement. We then review recommended modalities at each phase of perioperative care. We showcase the value of interprofessional collaboration in implementing and sustaining perioperative performance measures related to pain management and analgesic exposure, including those from the patient perspective. Surgery centers across the globe should adopt an integrated, collaborative approach to the twin goals of optimal pain management and opioid stewardship across the care continuum.

Barriers and Facilitators to the Prevention of Chronic Pain in the Subacute Phase After Cardiac Surgery

BACKGROUND

Although a transitional approach promoting continuity of care is warranted to prevent chronic post-surgical pain (CPSP) and opioid misuse, there is limited research examining interventions targeting the subacute phase after cardiac surgery. Contextual multi-level factors may explain this scarcity.

AIMS

The purpose of this study was to explore the potential implementation of a nursing intervention to prevent CPSP in the subacute phase by describing nurses' viewpoints of current barriers and facilitators.

DESIGN

A descriptive qualitative study was conducted using secondary data analysis.

SETTINGS

A Web-based survey was used along with in-person interviews.

PARTICIPANTS

75 perioperative nurses.

METHODS

Qualitative data from individual interviews (n=10) and open-ended responses to a survey (n=65) regarding the intervention's acceptability were used. Content analysis was conducted using a deductive approach.

RESULTS

The introduction of nurses from various clinical settings to a new intervention allowed reflection on current practice and represented a shift toward a preventive approach. The main barrier expressed was the lack of communication and continuity of care between clinical settings. Several policy implications were outlined such as increasing the involvement of rehabilitation programs and strengthening collaboration between pain specialists and primary care providers.

CONCLUSIONS

Based on perceptions of nurses involved at different stages of the continuum, the findings provide a preliminary picture of clinical challenges and potential avenues for the prevention of CPSP in the subacute phase after cardiac surgery. An expanded pain management nursing role in primary care would allow earlier interventions and contribute to the prevention of CPSP for a tremendous number of patients undergoing surgeries.

Nonpharmacologic Treatments for Opioid Reduction in Patients With Advanced Chronic Kidney Disease

Opioid analgesics carry risk for serious health-related harms in patients with advanced chronic kidney disease (CKD) and end-stage kidney disease. In the general population with chronic noncancer pain, there is some evidence that opioid reduction or discontinuation is associated with improved pain outcomes; however, tapering opioids abruptly or without providing supportive interventions can lead to physical and psychological harms and relapse of opioid use. There is emerging evidence that nonpharmacologic treatments such as psychosocial interventions, acupuncture, and interdisciplinary pain management programs are effective approaches to support opioid dose reduction in patients experiencing persistent pain, but research in this area still is relatively new. This review describes the current evidence for nonpharmacologic interventions to support opioid reduction in non-CKD patients with pain and discusses the application of the available evidence to patients with advanced CKD who are prescribed opioids to manage pain.

One-day Acceptance and Commitment Therapy workshop for preventing persistent post-surgical pain and dysfunction in at-risk veterans: A randomized controlled trial protocol

OBJECTIVE

Persistent post-surgical pain is common among patients undergoing surgery, is detrimental to patients' quality of life, and can precipitate long-term opioid use. The purpose of this randomized controlled trial is to assess the effects of a behavioral intervention offered prior to surgery for patients at risk for poor post-surgical outcomes, including persistent pain and impaired functioning.

METHODS

Described herein is an ongoing randomized, patient- and assessor-blind, attention-controlled multisite clinical trial. Four hundred and thirty Veterans indicated for total knee arthroplasty (TKA) with distress and/or pain will be recruited for this study. Participants will be randomly assigned to a one-day (~5 h) Acceptance and Commitment Therapy workshop or one-day education and attention control workshop. Approximately two weeks following their TKA surgery, patients receive an individualized booster session via phone. Following their TKA, patients complete assessments at 1 week, 6 weeks, 3 months, and 6 months.

RESULTS

The primary outcomes are pain intensity and knee-specific functioning; secondary outcomes are symptoms of distress and coping skills. Mediation analyses will examine whether changes in symptoms of distress and coping skills have an impact on pain and functioning at 6 months in Veterans receiving ACT. This study is conducted mostly with older Veterans; therefore, results may not generalize to women and younger adults who are underrepresented in this veteran population.

CONCLUSIONS

The results of this study will provide the first evidence from a large-scale, patient- and assessor-blind controlled trial on the effectiveness of a brief behavioral intervention for the prevention of persistent post-surgical pain and dysfunction.

Efficacy of motivational-interviewing and guided opioid tapering support for patients undergoing orthopedic surgery (MI-Opioid Taper): A prospective, assessor-blind, randomized controlled pilot trial

BACKGROUND

Postoperative opioid use can lead to chronic use and misuse. Few studies have examined effective approaches to taper postoperative opioid use while maintaining adequate analgesia.

METHODS

This randomized, assessor-blinded, pilot trial of postoperative motivational interviewing and guided opioid tapering support (MI-Opioid Taper) added to usual care (UC) enrolled patients undergoing total hip or knee arthroplasty at a single U.S. academic medical center. MI-Opioid Taper involved weekly (to seven weeks) and monthly (to one year) phone calls until patient-reported opioid cessation. Opioid tapering involved 25% weekly dose reductions. The primary feasibility outcome was study completion in the group to which participants were randomized. The primary efficacy outcome, time to baseline opioid use, was the first of five consecutive days of return to baseline preoperative dose. Intention-to-treat analysis with Cox proportional hazards regression was adjusted for operation. ClinicalTrials.gov registration: NCT02070003.

FINDINGS

From November 26, 2014, to April 27, 2018, 209 patients were screened, and 104 patients were assigned to receive MI-Opioid Taper (49 patients) or UC only (55 patients). Study completion after randomization was similar between groups (96.4%, 53 patients receiving UC, 91.8%, 45 patients receiving MI-Opioid Taper). Patients receiving MI-Opioid Taper had a 62% increase in the rate of return to baseline opioid use after surgery (HR 1.62; 95%CI 1.06-2.46; p = 0•03). No trial-related adverse events occurred.

INTERPRETATION

In patients undergoing total joint arthroplasty, MI-Opioid Taper is feasible and future research is needed to establish the efficacy of MI-Opioid Taper to promote postoperative opioid cessation.

The Use of Acceptance and Commitment Therapy in Substance Use Disorders: A Review of Literature

Background

Acceptance and commitment therapy (ACT) is a form of behavioral therapy that teaches people to learn to accept rather than avoid challenging situations in their lives. ACT has shown to be an intervention with great success in the reduction of various mental disorders and substance use disorders (SUDs). The core of ACT when used in SUD treatment is guiding people to accept the urges and symptoms associated with substance misuse (acceptance) and use psychological flexibility and value-based interventions to reduce those urges and the symptoms (commitment). The purpose of this study is to review the existing literature to examine the evidence on the use of ACT in the management of SUD.

Methods

A thorough search of four databases (CINAHL, PubMed.gov, PsycINFO and PsycNET) from 2011 to 2020 was conducted using search terms like ACT, ACT and SUD, ACT, and substance misuse. The articles retrieved were critically appraised using the Critically Appraised Topic (CAT) Checklist.

Results

Most of the studies showed that ACT was effective in the management of SUD showing significant evidence of a reduction in substance use or total discontinuation with subsequent abstinence.

Conclusions

The literature review concluded that success has been achieved using ACT either as monotherapy or in combination with other therapy in the treatment of individuals with SUD.

Mitigating the Effect of Pain Severity on Activity and Disability in Patients with Chronic Pain: The Crucial Context of Acceptance

OBJECTIVE

The purpose of this study was to examine the effect of pain severity on activity levels and physical disability in the context of high pain acceptance. We hypothesized that pain acceptance moderates the effect of pain severity on general activity and physical disability, such that at higher levels of acceptance, the deleterious effect of pain is mitigated.

METHODS

Two hundred seven patients with chronic pain were recruited from three clinics in a large southwestern military treatment facility. Participants completed an anonymous self-report battery of standardized measures, including the Chronic Pain Acceptance Questionnaire, modified Oswestry Disability Index, and Pain Severity and General Activity subscales of the West Haven-Yale Multidimensional Pain Inventory.

RESULTS

Chronic pain acceptance was found to significantly moderate relations between pain severity and general activity (b  =  0.0061, t(198) = 2.75, P = 0.007, 95% confidence interval [CI] = 0.002 to 0.011) and pain severity and disability (b  =  0.036, t(193) = -2.564, P = 0.011, 95% CI = -0.063 to -0.008). In the context of higher acceptance, the negative effect of pain on activity and disability appeared reduced. Conversely, in the context of low acceptance, the effect of pain on disability appeared accentuated at all levels of pain severity.

CONCLUSIONS

Higher acceptance mitigated both activity level and disability in a military-affiliated clinical sample of patients with chronic pain. Results further establish the role of acceptance in relation to functioning in a unique sample of people with chronic pain. These findings have implications for understanding and enhancing functioning in chronic pain populations.

Exploratory Study of Common Changes in Client Behaviors Following Routine Psychotherapy: Does Psychological Flexibility Typically Change and Predict Outcomes?

Psychological flexibility refers to a modifiable pattern of interacting with one’s experiences with openness and awareness (acceptance-and-mindfulness) and active engagement guided by personal values (commitment-and-behavioral activation). Psychological flexibility has a base of research literature that supports its utility as a model of human behavioral health and pathology. Although the model is central in organizing the therapeutic processes of Acceptance and Commitment Therapy, researchers have argued that psychological flexibility processes might be activated in other effective therapy models included in routine psychotherapy, even if those models do not purport to target those processes. This study explored the degree to which aspects of clients’ psychological flexibility, specifically acceptance-and-mindfulness and commitment-and-behavioral activation, changed after episodes of routine psychotherapy and were predictors of outcome changes for a clinically heterogeneous sample (n = 197) in a naturalistic treatment setting. Results showed statistically significant and small improvements in acceptance-and-mindfulness (d = 0.22) and commitment-and-behavioral activation (d = 0.24) and that changes in psychological flexibility were significant predictors of changes in both flourishing and distress, explaining 42% and 23% of those respective therapy outcomes. Whereas a mix of therapy approaches may slightly improve psychological flexibility, more explicit attention to strengthening it might benefit the work of diverse psychotherapists given its potential relevance to achieving common overarching therapy outcomes.

Acceptance and Commitment Therapy Delivered via a Mobile Phone Messaging Robot to Decrease Postoperative Opioid Use in Patients With Orthopedic Trauma: Randomized Controlled Trial

BACKGROUND

Acceptance and commitment therapy (ACT) is a pragmatic approach to help individuals decrease avoidable pain.

OBJECTIVE

This study aims to evaluate the effects of ACT delivered via an automated mobile messaging robot on postoperative opioid use and patient-reported outcomes (PROs) in patients with orthopedic trauma who underwent operative intervention for their injuries.

METHODS

Adult patients presenting to a level 1 trauma center who underwent operative fixation of a traumatic upper or lower extremity fracture and who used mobile phone text messaging were eligible for the study. Patients were randomized in a 1:1 ratio to either the intervention group, who received twice-daily mobile phone messages communicating an ACT-based intervention for the first 2 weeks after surgery, or the control group, who received no messages. Baseline PROs were completed. Two weeks after the operative intervention, follow-up was performed in the form of an opioid medication pill count and postoperative administration of PROs. The mean number of opioid tablets used by patients was calculated and compared between groups. The mean PRO scores were also compared between the groups.

RESULTS

A total of 82 subjects were enrolled in the study. Of the 82 participants, 76 (38 ACT and 38 controls) completed the study. No differences between groups in demographic factors were identified. The intervention group used an average of 26.1 (SD 21.4) opioid tablets, whereas the control group used 41.1 (SD 22.0) tablets, resulting in 36.5% ([41.1-26.1]/41.1) less tablets used by subjects receiving the mobile phone-based ACT intervention (P=.004). The intervention group subjects reported a lower postoperative Patient-Reported Outcome Measure Information System Pain Intensity score (mean 45.9, SD 7.2) than control group subjects (mean 49.7, SD 8.8; P=.04).

CONCLUSIONS

In this study, the delivery of an ACT-based intervention via an automated mobile messaging robot in the acute postoperative period decreased opioid use in selected patients with orthopedic trauma. Participants receiving the ACT-based intervention also reported lower pain intensity after 2 weeks, although this may not represent a clinically important difference.
