Don’t tell me, show me: Reactions from those with lived experience to the 2020 revised IASP definition of pain

Abstract In 2020, the International Association for the Study of Pain (IASP) revised the definition of pain, providing an update to IASP’s original definition in place since 1979. The origins of the field of pediatric pain, born in part in the 1980s from the advocacy of Jill Lawson, mother to Jeffrey Lawson who experienced gross inadequacies in pain care as a premature infant, emphasize the critical need to listen to and act with the voice of people living with pain and their families and caregivers. Furthermore, the field of pediatric pain emerged in the mid‐1980s marking this revised definition of pain as the first opportunity within which the experience and science of pain in childhood has been considered. This invited commentary offers two lived experience reactions to the revised IASP definition of pain, from the perspective of one's own experience with pain during childhood and as parents and family members. Together, they highlight that the value of a revised definition must be judged on its ability to directly benefit children experiencing pain and their families. Their skeptical hope reflects their lived experience backed by empirical evidence demonstrating continued inequities and inadequacies in preventing and managing pediatric pain.

Abstract
In 2020, the International Association for the Study of Pain (IASP) revised the definition of pain, providing an update to IASP's original definition in place since 1979. The origins of the field of pediatric pain, born in part in the 1980s from the advocacy of Jill Lawson, mother to Jeffrey Lawson who experienced gross inadequacies in pain care as a premature infant, emphasize the critical need to listen to and act with the voice of people living with pain and their families and caregivers. Furthermore, the field of pediatric pain emerged in the mid-1980s marking this revised definition of pain as the first opportunity within which the experience and science of pain in childhood has been considered. This invited commentary offers two lived experience reactions to the revised IASP definition of pain, from the perspective of one's own experience with pain during childhood and as parents and family members. Together, they highlight that the value of a revised definition must be judged on its ability to directly benefit children experiencing pain and their families. Their skeptical hope reflects their lived experience backed by empirical evidence demonstrating continued inequities and inadequacies in preventing and managing pediatric pain. We must mobilize together to ensure change in culture, knowledge, and behavior. With the combined efforts of researchers, healthcare professionals, and policymakers, in partnership with diverse people with lived experience, we can ensure that more effective action is taken to rapidly improve pain for children and their families.

lived experience, pain, pain definition, pain experience, parents, pediatric email discussions, and qualitative content analysis of public review comments. 8 Also important are the notes that accompany the revised definition of pain that highlight that: • Pain is always a personal experience that is influenced to varying degrees by biological, psychological, and social factors.
• Pain and nociception are different phenomena. Pain cannot be inferred solely from activity in sensory neurons.
• Through their life experiences, individuals learn the concept of pain.
• A person's report of an experience as pain should be respected.
• Although pain usually serves an adaptive role, it may have adverse effects on function and social and psychological well-being.
• Verbal description is only one of several behaviors to express pain; inability to communicate does not negate the possibility that a human or a nonhuman animal experiences pain. that transformative change will only occur through cross-sector collaboration between researchers, healthcare professionals, policymakers, funders, and patients and families. 3 In 2020 IASP formed the Global Alliance for Partners for Pain Advocacy (GAPPA), Task Force intended to champion the lived experience voice and perspective in IASP governance structure, membership models, special interest groups, organization chapters, organizational strategy, and programs. 1,4 The revolutionary origin of the field of pediatric pain was born in the mid-1980s by a mother with lived experience highlighting gross inadequacies in pain care, coupled with public outcry regarding the ethics of emerging science. 7 Jill Lawson advocated widely for improved pediatric pain care in the public media and in scientific journals, including a letter she published in the journal Birth detailing the cardiac surgery performed on her prematurely born son, Jeffrey Lawson, while he was conscious, given only paralytics so as not to move, and without anesthetic. 5 Jeffrey died 5 weeks later on March 31, 1985, after he suffered shock and multiple organ failure. What follows from this time is exponential growth in scientific study and improved practices focused on pain in infancy, childhood, and adolescence. 2

In my teenage years in the late 1980s I began to experience pain and disability. Almost overnight, I went from a high performance athlete and academic overachiever to somebody who didn't understand why her own body was betraying her. Pain became my daily companion and getting help was no easy task. While my own family showed unwavering support despite my mysterious symptoms, it was much more difficult over the ensuing years to get understanding from healthcare providers, educators, peers, and the support systems I needed in society. Not only was my pain invisible, but as we couldn't find a mechanical source for the pain, a diagnosis we could point to, indeed an 'associated actual or potential tissue damage' (what was then the IASP definition of pain 8 ), the longer I had pain without a diagnosis, the greater stigma and the less support I received. This was a long time ago. Time, as they say, marched on. One hoped things have changed for the better in a system that purports to value patient centered care, shared decision making, and patient partnership.
In the past few years, I have had incredible opportunities to work within the pain research community as a parent partner. I have come to understand how far the thinking has come within this research and clinical community and was heartened to see the new definition of pain come from the IASP. There is one phrase that is different, one word, that can create a sea change in care for those who experience pain. The addition of the phrase 'resembling that associated with' adds so much to the definition of pain because it highlights the subjective experience of pain in the definition. It creates space for autonomy, for a lack of diagnosis, for the fact that pain, in and of itself, is a diagnosis and needs to be treated, whether or not it is associated with a separate diagnosis with 'actual or potential tissue damage'.
After a heady moment of excitement at this change, I thought, so what? What happens next?
My experience with pain didn't end with me. I parent two children who have experienced pain, chronic and acute. They were not able to access pain care through specialized pain services until well into their 'pain journey' in their later teenage years. The I remember hosting a roundtable session for rare disease patients that was meant to help determine priorities in healthcare. One patient mentioned that in order to be taken seriously in the emergency department, they had to use a wheelchair that was needed on only a small handful of occasions. That stuck with me over the years as it provided context to my own experiences as a parent realizing how many times that I was probably gaslit about the severity of medical needs in tense moments. I don't know if I'd consider this slow revelation a survival tactic, but my faith in others was challenged with a great frequency. It was to a point where you had to anticipate the worst in potential outcomes from care relationships but hope for the good results. To me, a shift in definition, while inspired in nature, requires an examination of the biases that often impede its implementation. We need to consider self-examination and recognition of the work we still must do to address intersectional biases in gender, race, and disability. Nothing makes a patient or caregiver feel more helpless than a misaligned relationship in care that fails to examine the depth and nuance of managing one's quality of life. The stakes are so much higher with diagnoses that produce an alarming risk of suicidality.
Anton Chekhov is reputed to have said, "Don't tell me the moon is shining, show me the glint of light on broken glass". 9 While words have the capability of emotional connection and a building of trust, its impact is only truly felt with compassion, action and intent. Show us change for the better. Please.

Pain is lived and managed in the countless moments of each day, over months, and many years. These lived experiences are charged with emotion brought, in part, by frequent encounters with the health system that leave a continuous desire for improvement. Each lived experience is unique, and these are not meant to reflect all perspectives of people who have lived with pain during childhood or cared for those who do. What these two personal accounts reflect is a skeptical hope for the future. The words captured in the revised definition of pain must be enacted with observable change and impact in culture, knowledge, and behavior.
We have had a shared language to describe pain experience since 1979, in the original IASP definition of pain. 8 Despite this, more than 40 years later, equitable and widespread access to pain care for children remains problematic, evidence-based pediatric pain management practices are inconsistently implemented leading to preventable and undertreated pain, and pain education for healthcare professionals remains inadequate. 3 This suggests a pervasive lack of understanding of the definition of pain at the point of care and in the public. What use is a revised definition of pain if it does not actually benefit the people living with pain everyday? Who bears the responsibility to reach beyond the "pain community" to ensure this revised definition is put into action?
Our collective next steps require acknowledging that the work is not complete. It took more than 40 years to revise the definition of pain, and implementation cannot take so long, nor can the need to continuously review the definition over time. We must mobilize together. With the combined efforts of researchers, healthcare professionals, and policymakers, in partnership with diverse people with lived experience, we can ensure that more effective action is taken to rapidly improve pain for children and their families.
