Nonpharmacological interventions for acute pain management in patients with opioid abuse or opioid tolerance: a scoping review

Use of Biofeedback-Based Virtual Reality in Pediatric Perioperative and Postoperative Settings: Observational Study

BACKGROUND

Biofeedback-based virtual reality (VR-BF) is a novel, nonpharmacologic method for teaching patients how to control their breathing, which in turn increases heart rate variability (HRV) and may reduce pain. Unlike traditional forms of biofeedback, VR-BF is delivered through a gamified virtual reality environment, increasing the accessibility of biofeedback. This is the first study to systematically integrate VR-BF use in the pediatric perioperative setting, with the ultimate goal of evaluating the efficacy of VR-BF to reduce pain, anxiety, and opioid consumption once feasibility and acceptability have been established.

OBJECTIVES

The primary objective was to develop a clinical trial protocol for VR-BF use in the pediatric perioperative setting, including preoperative education and training, and postoperative application of VR-BF in children undergoing surgery. A secondary objective was to evaluate the patient and parent experience with VR-BF.

METHODS

A total of 23 patients (12-18 years of age) scheduled for surgery at Nationwide Children's Hospital were recruited using purposive sampling. Following training, participants independently completed a daily, 10-minute VR-BF session for 7 days before surgery and during their inpatient stay. Participants could use VR-BF up to 2 weeks after hospital discharge. Patient- and session-level data of VR-BF usage and achievement of target HRV parameters were measured to identify the optimal frequency and duration of sessions before and after surgery for this population. Standardized questionnaires and semistructured interviews were conducted to obtain qualitative information about patients' experiences with VR-BF.

RESULTS

Patient-level data indicated that the highest odds of achieving 1 session under target HRV parameters was after 4 sessions (odds ratio [OR] 5.1 for 4 vs 3 sessions, 95% CI 1.3-20.6; OR 16.6 for 3 vs 2 sessions, 95% CI 1.2-217.0). Session-level data showed that a session duration of 9 to 10 minutes provided the greatest odds of achieving 1 session under target HRV parameters (OR 1.3 for 9 vs 8 min, 95% CI 1.1-1.7; OR 1.4 for 8 vs 7 min, 95% CI 1.1-1.8; OR 1 for 10 vs 9 min, 95% CI 0.9-1.2). Qualitative data revealed patient satisfaction with the VR-BF technology, particularly in managing perioperative stress (17/20, 85%). Few patients reported VR-BF as beneficial for pain (8/20, 40%).

CONCLUSIONS

Children and adolescents undergoing surgery successfully learned behavioral strategies with VR-BF with 10-minute sessions once daily for 5 days. To integrate VR-BF as a therapeutic intervention in a subsequent clinical trial, patients will be instructed to complete three 10-minute sessions a day for 7 days after surgery.

Guided Imagery for Symptom Management of Patients with Life-Limiting Illnesses: A Systematic Review of Randomized Controlled Trials

Background: Patients with life-limiting illnesses receiving palliative care have a high symptom burden that can be challenging to manage. Guided imagery (GI), a complementary and integrative therapy in which patients are induced to picture mental images with sensory components, has proven in quasi-experimental studies to be effective as a complementary therapy for symptom management. Objective: To systematically review randomized controlled trials that report evidence of guided imagery for symptom management in patients with life-limiting illnesses. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline was followed for this review and the search strategy was applied in Medline, CINHAL, and Web of Science. The quality of articles was evaluated using the Cochrane Collaboration's Risk-of-Bias Tool 2 (RoB 2). The results are presented using the Guidance on the Conduct of Narrative Synthesis in Systematic Reviews. Results: A total of 8822 studies were initially identified through the search strategy, but after applying exclusion criteria, 14 randomized controlled trials were included in this review. The quality assessment revealed that four studies had a high risk of bias, nine had some concerns, and one had a low risk of bias. Out of the 14 studies, 6 evaluated oncological diagnosis, while the remaining 8 focused on nononcological diagnoses across 6 different diseases. GI was found to be effective in managing symptoms in 10 out of the 14 studies. Regardless of the disease stage, patients who received guided imagery experienced relief from anxiety, depression, pain, sleep disturbances, and fatigue. Conclusion: GI therapy has shown promising results regarding symptom management in palliative care patients with life-limiting illnesses at different stages.

Massage Therapy for Hospitalized Patients Receiving Palliative Care: A Randomized Clinical Trial

CONTEXT

Massage therapy is increasingly used in palliative settings to improve quality of life (QoL) and symptom burden; however, the optimal massage "dosage" remains unclear.

OBJECTIVES

To compare three massage dosing strategies among inpatients receiving palliative care consultation.

METHODS

At an urban academic hospital, we conducted a three-armed randomized trial examining three different doses of therapist-applied massage to test change in overall QoL and symptoms among hospitalized adult patients receiving palliative care consultation for any indication (Arm I: 10-min massage daily × 3 days; Arm II: 20-min massage daily × 3 days; Arm III: single 20-min massage). Primary outcome measure was single-item McGill QoL question. Secondary outcomes measured pain/symptoms, rating of peacefulness, and satisfaction with intervention. Data were collected at baseline, pre- and post-treatment, and one-day postlast treatment (follow-up). Repeated measure analysis of variance and paired t-test were used to determine significant differences.

RESULTS

Total n = 387 patients were 55.7 (±15.49) years old, mostly women (61.2%) and African-American (65.6%). All three arms demonstrated within-group improvement at follow-up for McGill QoL (all P < 0.05). No significant between-group differences were found. Finally, repeated measure analyses demonstrated time to predict immediate improvement in distress (P ≤ 0.003) and pain (P ≤ 0.02) for all study arms; however, only improvement in distress sustained at follow-up measurement in arms with three consecutive daily massages of 10 or 20 minutes.

CONCLUSION

Massage therapy in complex patients with advanced illness was beneficial beyond dosage. Findings support session length (10 or 20 minutes) was predictive of short-term improvements while treatment frequency (once or three consecutive days) predicted sustained improvement at follow-up.
