A systematic review of the added value of perioperative pain neuroscience education

Pain Neuroscience Education: Teaching People About Pain

Chronic pain is an ever-increasing global challenge, and few strategies have been shown to significantly alter this trajectory, and a pure pharmaceutical approach, especially opioids, is not the answer. To truly impact a person with chronic pain's life, current best-evidence supports changing their cognitions (how they think about their pain), moving more, and calming the peripheral and central nervous system, including non-pharmacological strategies. All healthcare providers, however, must use a unified strategy regardless of their professional designation, skillset, and clinical setting. One variable that spans all patient interactions is communication. All healthcare providers talk to patients, be it during informal, casual conversation or during specific medical education tied to diagnosis, prognosis, treatment, reassurance, and more. Current evidence supports teaching patients more about their pain experience, called pain neuroscience education (PNE), which has significant clinical benefits. Any provider may offer PNE, from physicians, pharmacists, therapists, psychologists, nurses, etc. Pain neuroscience education is shown to positively influence self-reported pain, disability, fear-avoidance, pain catastrophizing, movement, and healthcare utilization in patients with chronic pain. This commentary aims to introduce all healthcare providers to PNE, and how, along with non-pharmacological treatments (PNE+) have the ability to positively impact people's lives living with chronic pain.

The Mediating Role of Pain Cognitions and Pain Sensitivity in the Treatment Effect of Perioperative Pain Neuroscience Education in People Undergoing Surgery for Lumbar Radiculopathy

Though perioperative pain neuroscience education (PPNE) positively influences patients' surgical outcomes, little is known about the mechanisms behind this treatment's success. Therefore, this study aims to evaluate the potential mediating role of pain cognitions and pain sensitivity in the treatment effect of PPNE on postoperative quality of life in people undergoing surgery for lumbar radiculopathy. This secondary analysis uses data from 120 participants of a randomized controlled trial who were randomized to receive either PPNE or perioperative biomedical education before undergoing surgery for lumbar radiculopathy. Quality of life was assessed 1-year postsurgery using the short form 36-item health survey (SF36) physical and mental component scores. Potential mediators included pain cognitions (ie, kinesiophobia, pain catastrophizing, and hypervigilance) and pain sensitivity (ie, endogenous nociceptive modulation), assessed 6 weeks postsurgery. Mediation models were constructed using structural equation modeling, and 95% confidence intervals (CIs) were calculated using 10,000 bootstrap samples. Analyses show a significant total effect for PPNE (estimate = .464, 95% CI [.105, .825]) and a significant indirect effect via pain catastrophizing on the SF36 physical component (estimate = .124, 95% CI [.001, .293]). No mediating effect was found through the remaining pain cognitions or pain sensitivity measures. Also, no potential mediators were identified for the treatment effect of PPNE on the SF36 mental component. Our findings suggest that pain catastrophizing mediates the treatment effect of PPNE on physical health-related quality of life in people undergoing surgery for lumbar radiculopathy. PERSPECTIVE: This secondary analysis identified pain catastrophizing as a mediator for PPNE in people undergoing surgery for lumbar radiculopathy. More so, its findings indicate that this educational intervention can enhance the postoperative physical health-related quality of life of these patients by addressing their catastrophizing thoughts.

Pain Neuroscience Education in elective surgery patients: study protocol for a randomised controlled trial

BACKGROUND

Pain Neuroscience Education (PNE) consists of an educational strategy that seeks to understand the biological processes of pain and how to control it. The main objective of this study will be to evaluate the impact of PNE on outcomes related to the postoperative period. The hypothesis is that the intervention may positively influence postoperative recovery, contributing to pain control, clinical indications, acceptance and consumption of analgesics and other pharmacological drugs that contribute to its control, as well as psychological aspects, such as anxiety, depression and pain catastrophising.

METHODS AND ANALYSIS

This will be an open, parallel, multicentre and randomised controlled clinical trial. A total of 100 participants aged between 18 and 59 years of age, of both genders, who are going to have elective general surgery will be evaluated. The intervention group will participate in a preoperative pain neuroscience educational session and also receive usual preoperative care, while the control group receives usual preoperative care as well. The educational session will last 30 min and consists of a video (5:20 min), a questionnaire about the content, time for participants to express their beliefs, thoughts and doubts. Participants will be evaluated preoperatively and there will be one postintervention evaluation. The intensity and characteristics of pain and anxiety are evaluated as primary outcomes. As secondary outcomes, pain catastrophising and depression are taken into account.

ETHICS AND DISSEMINATION

The project was approved by the Research Ethics Committee of the Faculty of Ceilandia, the Research Ethics Committee of the Institute of Strategic Health Management of the Federal District and the Research Council of the Hospital of Brasília-Rede Dasa (CAAE: 28572420.3.0000.8093). Recruitment began in June of 2023. All participants were included in the study only after their written consent. All data obtained will be analysed and distributed through publication in journals and at scientific events.
