We need to talk: The urgent conversation on chronic pain, mental health, prescribing patterns and the opioid crisis.

The opioid crisis' pathways from first exposure onwards to eventual illnesses and fatalities are multiple, intertwined and difficult to dissect. Here, we offer a multidisciplinary appraisal of the relationships among mental health, chronic pain, prescribing patterns worldwide and the opioid crisis. Because the opioid crisis' toll is especially harsh on young people, emphasis is given on data regarding the younger strata of the population. Because analgesic opioid prescription constitute a recognised entry point towards misuse, opioid use disorder, and ultimately overdose, prescribing patterns across different countries are examined as a modifiable hazard factor along these pathways of risk. Psychiatrists are called to play a more compelling role in this urgent conversation, as they are uniquely placed to provide synthesis and lead action among the different fields of knowledge and care that lie at the crossroads of the opioid crisis. Psychiatrists are also ideally positioned to gauge and disseminate the foundations for diagnosis and clinical management of mental conditions associated with chronic pain, including the identification of hazardous and protective factors. It is our hope to spark more interdisciplinary exchanges and encourage psychiatrists worldwide to become leaders in an urgent conversation with interlocutors from the clinical and basic sciences, policy makers and stakeholders including clients and their families.

"Working Together": Perspectives of Healthcare Professionals in Providing Virtual Care to Youth with Chronic Pain during the COVID-19 Pandemic.

BACKGROUND: The onset of the coronavirus disease in 2019 necessitated a rapid transition to virtual care for chronic pain treatment. METHODS: A mixed methods design was implemented using qualitative interviews and quantitative satisfaction surveys. Interviews were conducted in February 2021 with a sample of healthcare professionals (HCPs; n = 6) who had provided multidisciplinary treatment (MDT) through an outpatient hospital pediatric chronic pain program. Satisfaction surveys were distributed to all MDT professionals employed by the clinic in April 2021 (n = 13 of 20 eligible; 65% response rate). Participants represented medicine, rehabilitation, and mental health professionals. RESULTS: Analysis of interviews generated five themes: (1) adaptation to virtual care, (2) benefits of virtual care, (3) limitations of virtual care, (4) shifting stance on virtual care over time, and (5) considerations for implementing virtual care. The satisfaction survey data revealed that respondents were able to effectively provide appropriate diagnoses, recommendations, and/or care plans for pediatric chronic pain via virtual care (n = 12, 92.3%). Detailed survey responses are presented by discipline. CONCLUSIONS: This study provides a rich exploration of HCPs' experiences in providing MDT for pediatric chronic pain within a virtual care model. The current results may contribute to the future development of guidelines for virtual care delivery with pediatric chronic pain populations.

"We survived the pandemic together”: The impact of the COVID-19 pandemic on Canadian families living with chronic pain

Introduction Pediatric chronic pain is a significant problem in Canada, affecting one in five youth. This study describes the impact of the pandemic on the experiences of Canadian families living with chronic pain through interviews with youth living with chronic pain, parents, and siblings. Methods Employing a qualitative descriptive design, in-depth semistructured interviews were completed with Canadian youth living with pain, as well as parents and siblings. Participants were not required to be related. Interviews were analyzed using a reflexive thematic analysis approach. Results Forty-four interviews were completed with 14 parents, 19 youth with chronic pain, and 11 siblings from across the country. Three key themes were developed: (1) absorbing and shifting: the toll of the pandemic on the family system (e.g., loss of coping mechanisms, shifting roles to respond to the pandemic), (2) social ambiguity and abandonment (e.g., social sacrifice and abandonment by the health care system), and (3) building community resilience: familial adaptation to the pandemic (e.g., family cohesion, confidence, and self-management). Discussion/Conclusions Youth, parents, and siblings reported that the pandemic impacted coping strategies across the family system. These results outline the challenges youth experienced managing their pain and overall health throughout the pandemic and the resilience built within families during this time. Going forward, it would be relevant to examine how racialized and structurally marginalized youth with chronic pain and their families experienced the pandemic. Future research should examine how unexpected benefits of the pandemic (e.g., increased confidence and self-management) may be sustained into the future.

Introduction: La douleur chronique pédiatrique est un problème important au Canada, qui touche un jeune sur cinq. Cette étude décrit les répercussions de la pandémie sur les expériences des familles canadiennes vivant avec la douleur chronique par des entrevues avec des jeunes vivant avec une douleur chronique, des parents et des frères et sœurs.Méthodes: À l'aide d'un devis descriptif qualitatif, des entretiens semi-structurés approfondis ont été réalisés auprès de jeunes Canadiens vivant avec la douleur, leurs parents, et leurs frères et sœurs. Il n'était pas nécessaire que les participants aient un lien familial. Les entretiens ont été analysés à l'aide d'une approche d'analyse thématique réflexive.Résultats: Quarante-quatre entretiens ont été réalisés auprès de 14 parents, 19 jeunes souffrant de douleur chronique et 11 frères et sœurs de tout le pays. Trois thèmes clés ont été abordés : (1) l'absorption et le changement : le coût de la pandémie pour le système familial (p. ex., perte de mécanismes d'adaptation, changement de rôles pour réagir à la pandémie), (2) l'ambiguïté sociale et l'abandon (p. ex., le sacrifice social et l'abandon par le système de soins de santé), et (3) le renforcement de la résilience communautaire : adaptation familiale à la pandémie (p. ex., cohésion familiale, confiance et auto-prise en charge).Discussion/Conclusions: Les jeunes, les parents et les frères et sœurs ont signalé que la pandémie avait eu des répercussions sur les stratégies d'adaptation dans l'ensemble du système familial. Ces résultats décrivent les défis rencontrés par les jeunes pour prendre en charge leur douleur et leur santé globale tout au long de la pandémie, ainsi que la résilience démontrée par les familles pendant cette période. À l'avenir, il serait pertinent d'examiner comment les personnes racialisées et les jeunes structurellement marginalisés souffrant de douleur chronique et leurs familles ont vécu la pandémie.Les recherches futures devraient examiner comment les avantages inattendus de la pandémie (par exemple, une confiance accrue et l'auto-prise en charge) peuvent être maintenus à l'avenir.

The Impact of the COVID-19 Pandemic on Youth with Chronic Pain and Their Parents: A Longitudinal Examination of Who Are Most at Risk.

OBJECTIVES: Chronic pain and mental illness in youth and parents are poised to reach new heights amidst the societal and healthcare impacts of the COVID-19 pandemic. Evidence from natural disasters (i.e., hurricanes) suggests that a degree of personal impact and individual personality may moderate the effects of high stress events, such as the COVID-19 pandemic, on mental health. METHODS: In a pre-existing cohort of 84 youth with chronic pain (Mage = 14.39; 12-18 years; 67.8% female) and 90 parents (86.7% female), we examined changes in youth pain interference and youth and parent mental health (depression, anxiety) from before to during the first wave of the COVID-19 pandemic, and the influence of personal impact of the pandemic (i.e., financial, familial, health, social, occupational, and educational domains) and individual personality (neuroticism, conscientiousness, extroversion). RESULTS: Overall, youth reported significantly lower pain interference and anxiety as compared to pre-pandemic; however, those more personally impacted by the pandemic reported worsening pain interference and anxiety symptoms. Overall, parents reported greater depressive symptoms as compared to pre-pandemic; however, those more personally impacted by the pandemic reported increased anxiety symptoms. Personality traits (high neuroticism, and low conscientiousness and extroversion) predicted worsened pain and mental health, and exacerbated effects of COVID-19-related personal impact on youth and parent anxiety symptoms. DISCUSSION: Identifying risk and resilience profiles in youth and parents at high risk for worsening pain and mental health may better inform matching interventions to individual need.

Ensuring Equity and Inclusion in Virtual Care Best Practices for Diverse Populations of Youth with Chronic Pain.

Poor access to care is a top patient-oriented research priority for youth with chronic pain in Canada, and the COVID-19 pandemic has exacerbated these concerns. Our patient-oriented project team engaged with marginalized and racialized youth with chronic pain (Black youth with sickle cell disease, Indigenous youth and youth with complex medical needs) and their families to ensure that best practice recommendations for virtual care are inclusive and equitable. Input provided through virtual round-table discussions improved recommendations for leveraging, implementing and selecting best platforms for virtual care for youth with chronic pain and identified new gaps for future research, practice and policy change.

Acceptability of an Adolescent Self-Management Program for Juvenile Idiopathic Arthritis.

OBJECTIVE: The study objective was to test the acceptability of a self-management program (SMP) for adolescents with juvenile idiopathic arthritis (JIA) focused on disease information, self-management, and social support needs. METHODS: This study was conducted using inductive qualitative methods to explore the acceptability of an in-person/videoconference SMP. Two groups of four adolescents with JIA (mean age = 13.5, SD = 0.8) and two groups of pediatric rheumatology health care professionals (n = 4, n = 5) participated in four feedback sessions each. The SMP was presented to study participants, and feedback was provided on the content, format, and structure of the program. Thematic analysis was used to analyze the data. RESULTS: Adolescents felt that the content was appropriate and would be effective in supporting self-management of their arthritis. Participants advised that the trustworthiness of the information would be increased if a rheumatology health care provider facilitated the session. Potential barriers to participation included distance and availability (weekdays and times), but the option for videoconference-based participation was an appropriate solution to both of these issues. Minor changes were made to content and format, and required changes were made to address participant recommendations for improvement. CONCLUSION: This study confirmed the acceptability of an in-person/videoconference SMP for patients with JIA. Modifications were made to the SMP based on the focus group feedback, and future directions include a pilot randomized controlled trial to assess feasibility and preliminary effectiveness of the program.

Experiences of Pediatric Pain Professionals Providing Care during the COVID-19 Pandemic: A Qualitative Study.

Chronic pain affects 1 in 5 youth, many of whom manage their pain using a biopsychosocial approach. The COVID-19 pandemic has impacted the way that healthcare is delivered. As part of a larger program of research, this study aimed to understand the impact of the pandemic on pediatric chronic pain care delivery including impact on patients' outcomes, from the perspective of pediatric healthcare providers. A qualitative descriptive study design was used and 21 healthcare providers from various professional roles, clinical settings, and geographic locations across Canada were interviewed. Using a reflexive thematic analysis approach 3 themes were developed: (1) duality of pandemic impact on youth with chronic pain (i.e., how the pandemic influenced self-management while also exacerbating existing socioeconomic inequalities); (2) changes to the healthcare system and clinical practices (i.e., triaging and access to care); (3) shift to virtual care (i.e., role of institutions and hybrid models of care). These findings outline provider perspectives on the positive and negative impacts of the pandemic on youth with chronic pain and highlight the role of socioeconomic status and access to care in relation to chronic pain management during the pandemic in a high-income country with a publicly funded healthcare system.

Pediatric Chronic Pain in the Midst of the COVID-19 Pandemic: Lived Experiences of Youth and Parents.

During the coronavirus 2019 (COVID-19) pandemic youth with chronic pain have experienced additional barriers to accessing treatment and managing their pain. This study explored the experiences of youth with chronic pain and their parents during the COVID-19 pandemic. Individual semi-structured interviews were conducted with 20 youth with chronic pain (aged 13-20 years) and one of their parents, recruited from a tertiary level pediatric chronic pain program. Interviews occurred between the months of June to August 2020 and enabled participants to describe their experiences of the COVID-19 pandemic according to their own unique perspectives. Transcripts were analyzed using inductive reflexive thematic analysis. Four themes were generated and labelled: "temporality, mental health, and pain," "coping with pain during a global pandemic," "impact on care," and "re-appraisal in the context of development and pandemic life." Across these themes, youth and parents described their unique challenges of living with pain as they adapted to changing circumstances of the COVID-19 pandemic. Notably, youth experienced increased difficulties managing their mental health and pain, which were intricately connected and related to social isolation, temporality, and uncertainty exacerbated by the COVID-19 pandemic. Restrictions due to the COVID-19 pandemic impacted youth's access to care and their abilities to engage in coping strategies to manage their pain. The COVID-19 pandemic was also perceived to have interrupted youth's development and growing autonomy, prompting youth to re-appraise their current circumstances and imagined futures. PERSPECTIVE: This manuscript provides an in-depth understanding of the impact of the COVID-19 pandemic on youth with chronic pain and their parents. Youth and their parents perceived the COVID-19 pandemic to have impacted youth's mental health, pain, socio-emotional development, and access to care.

State of the Art: Immersive Technologies for Perioperative Anxiety, Acute, and Chronic Pain Management in Pediatric Patients.

Purpose of Review: This review summarizes and provides a comprehensive narrative synthesis of the current evidence on immersive technology's (i.e., virtual and augmented Reality) use for perioperative anxiety, acute, and chronic pain in pediatrics. Recent Findings: Researchers have increasingly studied immersive technology as a non-pharmacological alternative for perioperative anxiety, acute, and chronic pain management. We found several research studies published over the last 3 years: almost all studies examined the use of virtual reality for perioperative anxiety and pain; only one case report was about the use of augmented reality for preoperative anxiety. Most studies showed that virtual reality intervention is effective and safe for perioperative anxiety, acute, and chronic pain. However, the studies are heterogeneous with relatively small sample sizes. Summary: This review shows that more high-quality studies (i.e., randomized controlled trials with larger sample sizes and standardized methods for measuring and reporting outcomes) are needed to examine the effectiveness and adverse effects of virtual reality intervention on perioperative anxiety, acute, and chronic pain in pediatrics.

Best practices for virtual care to support youth with chronic pain and their families: a rapid systematic review to inform health care and policy during COVID-19 and beyond.

The COVID-19 pandemic has acutely challenged health systems and catalyzed the need for widescale virtual care and digital solutions across all areas of health, including pediatric chronic pain. The objective of this rapid systematic review was to identify recommendations, guidelines, and/or best practices for using virtual care to support youth with chronic pain and their families (CRD42020184498). MEDLINE, CINAHL, Embase, APA PsychINFO, and Web of Science were searched the week of May 25, 2020, for English language peer-reviewed articles published since 2010 that (1) discussed children and adolescents aged <18 years reporting any type of chronic pain (ie, pain lasting >3 months); (2) focused on any type of virtual care (eg, telephone, telehealth, telemedicine, mHealth, eHealth, online, or digital); and (3) reported on guidelines, best practices, considerations, or recommendations for virtual care. Abstract and full text screening and data extraction were performed in duplicate. Meta-ethnography was used to synthesize concepts across articles. Of 4161 unique records screened, 16 were included addressing diverse virtual care and pediatric chronic pain conditions. Four key themes were identified: (1) opportunities to better leverage virtual care, (2) direct effective implementation of virtual care, (3) selection of virtual care platforms, and (4) gaps in need of further consideration when using virtual care to support youth with chronic pain and their families. No existing guidelines for virtual care for pediatric chronic pain were identified; however, best practices for virtual care were identified and should be used by health professionals, decision makers, and policymakers in implementing virtual care.

Rapid Evidence and Gap Map of virtual care solutions across a stepped care continuum for youth with chronic pain and their families in response to the COVID-19 pandemic.

ABSTRACT: Poor access to pediatric chronic pain care is a longstanding concern. The COVID-19 pandemic has necessitated virtual care delivery at an unprecedented pace and scale. We conducted a scoping review to create an interactive Evidence and Gap Map of virtual care solutions across a stepped care continuum (ie, from self-directed to specialist care) for youth with chronic pain and their families. Review methodology was codesigned with 8 youth with chronic pain and 7 parents/caregivers. Data sources included peer-reviewed scientific literature, gray literature (app stores and web sites), and a call for innovations. Records were independently coded and assessed for quality. Overall, 185 records were included (105 scientific records, 56 apps, 16 web sites, and 8 innovations). Most virtual care solutions were applicable across pediatric chronic pain diagnoses, with the greatest proportion at lower levels of stepped care (ie, >100 self-guided apps and web sites). Virtual delivery of psychological strategies was common. Evidence gaps were noted at higher levels of stepped care (ie, requiring more resource and health professional involvement), integration with health records, communication with health professionals, web accessibility, and content addressing social/family support, medications, school, substance use, sleep, diet, and acute pain flares or crises. Evidence and Gap Maps are a novel visual knowledge synthesis tool, which enable rapid evidence-informed decision-making by patients and families, health professionals, and policymakers. This evidence and gap map identified high-quality virtual care solutions for immediate scale and spread and areas with no evidence in need of prioritization. Virtual care should address priorities identified by youth with chronic pain and their families.

COVID-19 Pandemic Impact and Response in Canadian Pediatric Chronic Pain Care: A National Survey of Medical Directors and Pain Professionals.

Background: The COVID-19 pandemic presents one of the greatest threats to pediatric pain care seen in generations. Due to public health restrictions, many pediatric pain clinics halted in-person appointments, delaying and disrupting access to care. There is no existing research on the impacts of COVID-19 on pediatric chronic pain care in Canada or the challenges experienced by health care professionals and pain clinics. Aims: The aim of this study was to evaluate the impact of COVID-19 on Canadian pediatric chronic pain care by documenting how health care professionals provided care during the first six months of the pandemic. Methods: Two Canadian online cross-sectional surveys were conducted: one among Canadian pediatric pain clinic directors (Study 1) and another among multidisciplinary pediatric pain health care professionals (Study 2). Results: Responses from 13/13 Canadian pediatric pain clinics/rehabilitation programs indicated that all clinics provided virtual care during the pandemic. No significant changes were reported on the frequency of appointment requests. Most clinics reported no perceived change in patient pain levels (n = 9/13, 69%) or occurrence of pain flares (n = 10/13, 77%). Results from 151 individual health care professionals indicated that the majority (90%) of non-emergency department respondents were providing virtual care. The main challenges of virtual care included technological barriers, financial concerns, infrastructure and logistics, privacy, and clinical challenges. Conclusions: This study documented the impact of the COVID-19 pandemic on pediatric chronic pain care in Canada and highlighted the rapid shift to using virtual solutions. Simultaneously, respondents outlined current challenges and potential solutions to consider in the development of virtual care guidelines and policy in Canada.

Contexte: La pandémie de COVID-19 représente l'une des plus grandes menaces pour les soins de la douleur pédiatrique jamais connue depuis des générations. En raison de restrictions de santé publique, de nombreuses cliniques pédiatriques de la douleur ont interrompu les rendez-vous en personne, occasionnant ainsi des retards et des perturbations dans l'accès aux soins. Il n'existe pas de recherche sur les répercussions de la COVID-19 sur les soins pédiatriques de la douleur chronique au Canada ou sur les défis rencontrés par les professionnels des soins de santé et les cliniques de la douleur.Objectifs: L'objectif de cette étude était d'évaluer les répercussions de la COVID-19 sur les soins pédiatriques de la douleur chronique au Canada en documentant la façon dont les professionnels de la santé ont prodigué les soins au cours des six premiers mois de la pandémie.Méthodes: Deux enquêtes transversales canadiennes en ligne ont été menées : l'une auprès des directeurs de cliniques pédiatriques de la douleur canadiennes (Étude 1) et l'autre auprès de professionnels des soins de santé de la douleur pédiatriques multidisciplinaires (étude 2).Résultats: Les réponses obtenues de la part de 13 / 13 cliniques pédiatriques de la douleur / programmes de réadaptation ont indiqué que toutes les cliniques avaient fourni des soins virtuels pendant la pandémie. Aucun changement significatif n'a été rapporté sur la fréquence des demandes de rendez-vous. La plupart des cliniques n'ont signalé aucun changement perçu dans les niveaux de douleur des patients (n = 9/13, 69 %) ou la survenue de poussées douloureuses (n = 10/13, 77 %). Les résultats obtenus de 151 professionnels de la santé ont indiqué que la majorité (90 %) des répondants de département autres que les urgences fournissaient des soins virtuels. Les principaux défis des soins virtuels comprenaient les barrières technologiques, les préoccupations financières, l'infrastructure et la logistique, la confidentialité et les défis cliniques.Conclusions: Cette étude a documenté les répercussions de la pandémie de COVID-19 sur les soins pédiatriques de la douleur chronique au Canada et a mis en lumière le passage rapide à l'utilisation de solutions virtuelles. Simultanément, les répondants ont décrit les défis actuels et les solutions potentielles devant être tenues en compte dans l'élaboration de lignes directrices et de politiques sur les soins virtuels au Canada.

Rapid mobilization of a virtual pediatric chronic pain clinic in Canada during the COVID-19 pandemic.

BACKGROUND: Studies have been conducted describing the potential for using virtual care software during disasters and public health emergencies. However, limited data exist on ways in which the Canadian health care system utilizes virtual care during disasters or public health emergencies. AIMS: Due to the need for social distancing and reduction of nonessential ambulatory services during the COVID-19 pandemic, the SickKids Chronic Pain Clinic sought to transition care delivery from in person to virtual. The virtual clinic aimed to reduce risks associated with physical contact and environmental exposure without reducing access to care itself. METHODS: Harnessing of various digital tools including Ontario Telemedicine Network Guestlink, Zoom, and Microsoft Teams. The Chronic Pain Clinic Team worked together to communicate with patients and families, schedule virtual visits, establish remote access to clinical data collection tools, digitize the after-visit summary, and add resources on pain self-management to the clinic's website. RESULTS: The Chronic Pain Clinic successfully transitioned all clinic appointments (multidisciplinary and individual; 77 appointments) over a 2-week period to virtual care. Virtual clinics did not surpass the usual time taken pre-COVID-19, suggesting that the clinic workflow was readily adaptable to virtual care. CONCLUSIONS: Access to quality virtual care is essential to prevent chronic pain from taking a toll on the lives of patients and families. Rapid establishment of a virtual clinic without gaps in service delivery to patients is possible given institutional support and a team culture centered around collaboration and flexibility.

Contexte: Des études ont été menées pour décrire le potentiel d'utilisation des logiciels de soins virtuels lors de catastrophes et d'urgences de santé publique. Toutefois, il existe peu de données sur les moyens par lesquels le systéme de soins de santé canadien utilise les soins virtuels lors de catastrophes ou d'urgences de santé publique.But: En raison de la nécessité d'une distanciation sociale et de la réduction des services ambulatoires non essentiels pendant la pandémie de COVID-19, la clinique de douleur chronique de SickKids a cherché à assurer une transition de la prestation des soins en personne vers des soins virtuels. La clinique virtuelle visait à réduire les risques liés au contact physique et à l'exposition environnementale sans réduire l'accès aux soins en tant que tels.Méthodes: Exploitation de divers outils numériques, dont le Réseau de télémédecine de l'Ontario Guestlink, Zoom et Microsoft Teams. L'équipe de la Clinique de la douleur chronique a travaillé ensemble pour communiquer avec les patients et les familles, programmer des visites virtuelles, établir un accès à distance aux outils de collecte de données cliniques, numériser le résumé après la visite et ajouter des ressources sur l'auto-prise en charge de la douleur sur le site web de la clinique.Résultats: La Clinique de la douleur chronique a réussi à faire passer tous les rendez-vous de la clinique (multidisciplinaires et individuels; 77 rendez-vous) sur une période de deux semaines à des soins virtuels. Les cliniques virtuelles n'ont pas dépassé le temps habituel avant la COVID-19, ce qui indique que le flux de travail de la clinique était facilement adaptable aux soins virtuels.Conclusions: L'accès à des soins virtuels de qualité est essentiel pour éviter que la douleur chronique ne fasse des ravages dans la vie des patients et des familles. L'établissement rapide déune clinique virtuelle sans interruption dans la prestation des services aux patients est possible grâce à un soutien institutionnel et à une culture d'èquipe centrèe sur la collaboration et la souplesse.
