Psychological Factors Influencing Healthcare Utilization in Breast Cancer Survivors with Pain.

INTRODUCTION: Pain is a prevalent side-effect seen in breast cancer survivors (BCS). Psychological factors are known role-players in pain mechanisms. Both pain and psychological factors contribute to or interact with healthcare use (HCU). However, the association between psychological factors and HCU has never been investigated in BCS with pain, which is aimed in this study. METHODS: Belgian BCS with pain (n = 122) were assessed by the Medical Consumption Questionnaire, Injustice Experienced Questionnaire, Pain Catastrophizing Scale, Pain Vigilance and Awareness Questionnaire, Brief Illness Perceptions Questionnaire, and the Depression, Anxiety and Stress Scale. Associations were analyzed using logistic and Poisson regressions. RESULTS: Opioid use was related to more catastrophizing and less psychological distress. Psychotropic drug was related to more psychological distress. Endocrine therapy related to less vigilance and awareness. Psychological distress related to all types of healthcare provider (HCP), with psychological distress negatively related to physiotherapy, psychology, and other primary HCP visits, and positively with visiting a general practitioner and secondary HCP. Catastrophizing related to more visiting behavior in primary HCP, except to a general practitioner. Perceived injustice related to more general practitioner and other primary HCP visits, but to fewer psychology visits. Illness perceptions are only related to visiting other primary HCP. Vigilance and awareness was related to more psychologist and secondary HCP visits. CONCLUSION: Our findings underscore the complex interplay between HCU and psychological factors in BCS with pain. Psychological distress was overall the most important psychological factor related to HCU, whether catastrophizing and perceived injustice were the most relevant related to HCP visits.

Personalized Multimodal Lifestyle Intervention as the Best-Evidenced Treatment for Chronic Pain: State-of-the-Art Clinical Perspective.

Chronic pain is the most prevalent disease worldwide, leading to substantial disability and socioeconomic burden. Therefore, it can be regarded as a public health disease and major challenge to scientists, clinicians and affected individuals. Behavioral lifestyle factors, such as, physical (in)activity, stress, poor sleep and an unhealthy diet are increasingly recognized as perpetuating factors for chronic pain. Yet, current management options for patients with chronic pain often do not address lifestyle factors in a personalized multimodal fashion. This state-of-the-art clinical perspective aims to address this gap by discussing how clinicians can simultaneously incorporate various lifestyle factors into a personalized multimodal lifestyle intervention for individuals with chronic pain. To do so the available evidence on (multimodal) lifestyle interventions targeting physical (in)activity, stress, sleep and nutritional factors, specifically, was reviewed and synthetized from a clinical point of view. First, advise is provided on how to design a personalized multimodal lifestyle approach for a specific patient. Subsequently, best-evidence recommendations on how to integrate physical (in)activity, stress, sleep and nutritional factors as treatment targets into a personalized multimodal lifestyle approach are outlined. Evidence supporting such a personalized multimodal lifestyle approach is growing, but further studies are needed.

Effect of perceived injustice-targeted pain neuroscience education compared with biomedically focused education in breast cancer survivors: a study protocol for a multicentre randomised controlled trial (BCS-PI trial).

INTRODUCTION: Current treatments for pain in breast cancer survivors (BCSs) are mostly biomedically focused rather than biopsychosocially driven. However, 22% of BCSs with pain are experiencing perceived injustice, which is a known predictor for adverse pain outcomes and opioid prescription due to increased maladaptive pain behaviour. Educational interventions such as pain neuroscience education (PNE) are suggested to target perceived injustice. In addition, motivational interviewing can be an effective behavioural change technique. This trial aims to examine whether perceived injustice-targeted PNE with the integration of motivational interviewing is superior to biomedically focused pain education in reducing pain after 12 months in BCS with perceived injustice and pain. In addition, improvements in quality of life, perceived injustice and opioid use are evaluated, and a cost-effectiveness analysis will finally result in a recommendation concerning the use of perceived injustice-targeted PNE in BCSs with perceived injustice and pain. METHODS AND ANALYSIS: This two-arm multicentre randomised controlled trial will recruit female BCS (n=156) with pain and perceived injustice. Participants will be randomly assigned to perceived injustice-targeted PNE or biomedically focused pain education in each centre. Both interventions include an online session, an information leaflet and three one-to-one sessions. The primary outcome (pain), secondary outcomes (quality of life, perceived injustice and outcomes for cost-effectiveness analysis) and explanatory outcomes (pain phenotyping, sleep, fatigue and cognitive-emotional factors) will be assessed at baseline and at 0, 6, 12 and 24 months postintervention using self-reported questionnaires online. Treatment effects over time will be evaluated using linear mixed model analyses. Additionally, a cost-utility analysis will be done from a healthcare payer and societal perspective. ETHICS AND DISSEMINATION: The ethical agreement was obtained from the Main Ethics Committee (B.U.N.1432020000068) at the University Hospital Brussels and all other participating hospitals. Study results will be disseminated through presentations, conferences, social media, press and journals. TRIAL REGISTRATION NUMBER: NCT04730154.
