Opioids for the management of severe chronic nonmalignant pain in children: a retrospective 1-year practice survey in a children's hospital

Shifting interpretations in evidence and guidance in pain and opioids research: A bibliometric analysis of a highly cited case series from 1986

RATIONALE, AIMS AND OBJECTIVES: Portenoy and Foley's 1986 landmark case series 'Chronic use of opioid analgesics in non-malignant pain: report of 38 cases' has been reproached for opening the floodgates of opioid prescribing for chronic non-cancer pain and the attendant harms. This influential article has been cited over 500 times in the scientific literature over the last four decades. This study seeks to understand the impact of Portenoy and Foley's article on subsequent discussions and research about opioids.

METHODS

We conducted a multi-method bibliometric analysis of all citations of this article from 1986 through 2019 using quantitative relational and qualitative content analysis to determine how uses and interpretations of this case series and associated prescribing guidance have changed over time, in relationship to the evolution of the North American opioid crises.

RESULTS

Using time series analysis, we identified three periods with distinct interpretations and uses of the index article. In the first 'exploration' period (1986-1996), the index article was well-received by the scientific community and motivated further study of the effects of opioids. In the second 'implementation' period (1997-2003, coinciding with the release of OxyContin®), this case series was used as evidence to support widespread prescribing of opioid analgesics, even while it was recognized that long-term effects had not yet been evaluated. The third 'reassessment' period (2004-2019) focused on how opioid-related harms had been overlooked, and in many cases, these harms were directly attributed to this article.

CONCLUSION

These changes in interpretation demonstrate shifting currents of the use and mobilization of evidence regarding pain and opioids, and how these currents both impact and are impacted by clinical practices and major sociohistorical phenomena such as the opioid crisis. Researchers and clinicians must account for these shifting dynamics when developing and interpreting scientific knowledge, including in the form of clinical practice guidelines.

Pain in child patients: A review on managements

Pain has been known as one of the major universal health concerns about ill children, because of its morbidity and potential mortality. Pain suitable evaluation is a challenge in children because the verbalization is difficult. Low clinical information, few pediatric researches, and the worry of opioid side effects make difficult to provide satisfactory treatments. Many pharmacologic and non-pharmacologic strategies to manage pain exist for pediatric pain treatment. The purpose of this review article is to describe exhaustively pain mechanism, evaluation and management by review literature from January 2000 to January 2019 using PubMed, EMBASE, MEDLINE, LILACS databases. Pharmacological and integrative non-pharmacological therapies has been indicated in acute and chronic pain treatment. Opioids and opioid-sparing agents target nociceptive and neuropathic pain. With due attention to available results, an early combination of pharmacological and integrative non pharmacological treatments are indicated in children pain management.

Receipt of multiple outpatient opioid prescriptions is associated with increased risk of adverse outcomes in youth: opioid prescribing trends, individual characteristics, and outcomes from 2005 to 2016

Data on all outpatient opioid prescriptions (N = 71,647) to youth below age 21 (N = 42,020) from 2005 to 2016 were extracted from electronic medical records within a university hospital system in New Mexico (NM) as were demographic details and markers of morbidity/mortality. Relative risk was calculated for markers of morbidity/mortality based on sociodemographic characteristics. The sample was primarily male (55.0%), Hispanic/Latinx (50.1%), English-speaking (88.9%), and publicly insured (50.1%). Mean age was 13.54 (SD = 6.50). From 2005 to 2016, overall frequency of opioid prescriptions increased by 86.6% (from 2470 to 4610) with the largest increase (206.2%) observed from 2005 to 2008 (2470-7562). Patients who were older, white, and non-Hispanic were more likely to receive multiple opioid prescriptions. Large relative increases in morbidity and mortality were documented, although base rates remained low. The percentage of individuals within the sample who experienced an overdose increased steadily from 0 in 2005 to 1.09% in 2016. Incidence of mortality increased from 0.12% of the sample to 1.39% in 2016. The proportion of individuals who received a medication for the treatment of opioid dependence increased from 0.06% in 2005 to 0.44% in 2016. Significantly increased risk of adverse outcomes was observed in patients receiving multiple opioid prescriptions, and in patients who were older, of minority race, received their first prescription in an outpatient clinic, and publicly insured or uninsured. Results add to the growing literature concerning opioid prescription rates over time. They also provide important information on potential additive risks of adverse outcomes when pediatric patients receive multiple opioid prescriptions.

Multidisciplinary Pain Management for Pediatric Patients with Acute and Chronic Pain: A Foundational Treatment Approach When Prescribing Opioids

Opioid therapy is the cornerstone of treatment for acute procedural and postoperative pain and is regularly prescribed for severe and debilitating chronic pain conditions. Although beneficial for many patients, opioid therapy may have side effects, limited efficacy, and potential negative outcomes. Multidisciplinary pain management treatments incorporating pharmacological and integrative non-pharmacological therapies have been shown to be effective in acute and chronic pain management for pediatric populations. A multidisciplinary approach can also benefit psychological functioning and quality of life, and may have the potential to reduce reliance on opioids. The aims of this paper are to: (1) provide a brief overview of a multidisciplinary pain management approach for pediatric patients with acute and chronic pain, (2) highlight the mechanisms of action and evidence base of commonly utilized integrative non-pharmacological therapies in pediatric multidisciplinary pain management, and (3) explore the opioid sparing effects of multidisciplinary treatment for pediatric pain.

Pharmacological Strategies for Decreasing Opioid Therapy and Management of Side Effects from Chronic Use

As awareness increases about the side effects of opioids and risks of misuse, opioid use and appropriate weaning of opioid therapies have become topics of significant clinical relevance among pediatric populations. Critically ill hospitalized neonates, children, and adolescents routinely receive opioids for analgesia and sedation as part of their hospitalization, for both acute and chronic illnesses. Opioids are frequently administered to manage pain symptoms, reduce anxiety and agitation, and diminish physiological stress responses. Opioids are also regularly prescribed to youth with chronic pain. These medications may be prescribed during the initial phase of a diagnostic workup, during an emergency room visit; as an inpatient, or on an outpatient basis. Following treatment for underlying pain conditions, it can be challenging to appropriately wean and discontinue opioid therapies. Weaning opioid therapy requires special expertise and care to avoid symptoms of increased pain, withdrawal, and agitation. To address this challenge, there have been enhanced efforts to implement opioid-reduction during pharmacological therapies for pediatric pain management. Effective pain management therapies and their outcomes in pediatrics are outside the scope of this paper. The aims of this paper were to: (1) Review the current practice of opioid-reduction during pharmacological therapies; and (2) highlight concrete opioid weaning strategies and management of opioid withdrawal.

Complex Pain in Young Children

Objective

Early childhood is a time of rapid development, particularly of the central nervous system, and can set a foundation for the entire life course. Complex pain in young children can impact the quality of life through limiting physical and social development, compromising psychological well-being, and disrupting sleep. The aim of this review is to identify the needs of young children who present to a tertiary-level pain service, what services they require, and their treatment outcomes. There are limited data on this vulnerable population, which may be due to small numbers represented and the complexities of pain assessment in this age group.

Methods

A retrospective chart review recorded demographics, gender, pain location and etiology, treatment, and outcomes of 28 children younger than age eight years attending a pediatric pain clinic over a three-year period.

Results

All but two young children had an obvious physical pathology as an explanation for pain; this is in contrast to studies of pain clinics servicing adolescents. A diverse range of conditions, some rare, were identified, requiring a high level of pediatric understanding of the disease process and an ability to work with primary teams with expertise in disease-modifying strategies.

The epidemiology of outpatient pain treatment in pediatrics

Background

There is limited real-world, population-level data on the prevalence and treatment of pain in children. An understanding of pediatric pain conditions and its management can help inform provider education, treatment guidelines, and design of pediatric pain studies. Therefore, in this study, we aimed to describe the prevalence of conditions associated with acute and chronic pain in pediatric patients and to characterize pediatric pain treatment with nonsteroidal anti-inflammatory drugs, cyclooxygenase-2 (COX-2) inhibitors, opioids (immediate release or extended release), antidepressants, topical analgesics, anticonvulsants, and other therapies based on a large, real-world sample.

Materials and methods

In this cohort study, we used administrative claims data from the Truven Health MarketScan^® Research Databases, which contain data regarding demography, prescription, diagnosis, and procedure performed. Descriptive statistics were used to assess the prevalence of various conditions associated with pediatric pain and to estimate the proportion of patients who received various analgesic and nonanalgesic treatments. All analyses were stratified according to demographics.

Results

This study included data on more than 30 million pediatric patients from throughout the US. Overall, among patients with commercial insurance, surgery was the most common pain-related diagnosis, followed by orthopedic conditions, malignancies, trauma, and genetic conditions. For patients with Medicaid, surgery was also the most common diagnosis, followed by traumatic injury, orthopedic conditions, malignancies, and genetic conditions. These diagnoses varied by age, with most showing higher prevalence in older children. Treatment varied substantially by condition, and many children (more than 50% for most of the conditions evaluated) did not receive any prescription pain treatments. For patients with either commercial insurance or Medicaid who were using prescription opioids, immediate-release opioids were the most commonly used analgesic treatment for pain. Overall, prescription pain treatments were more common in the Medicaid population. Extended-release opioids were rarely used.

Conclusion

The types of pain treatments varied substantially by condition and age of the patient, with the highest prevalence of use in older children.

Profile of children with developmental disabilities attending a complex pain clinic of a children's hospital in Australia

AIM

To document the profile and management of children with developmental disabilities (DD) attending an outpatient complex pain clinic at a Children's Hospital in Sydney, Australia.

METHODS

Children with DD from 2011 to 2014 were identified from a clinic database, and pain relevant data was collected.

RESULTS

A total of 107 (19.6%) of 544 children were identified with DD, and accounted for one-third of clinic attendances. The median age was 14 years (interquartile range: 11-16) and females were slightly over-represented (62, 57.9%). About one-third of children had cerebral palsy (CP) from a variety of prenatal, natal and post-neonatal causes. The lower limb was the most common site for pain in children with CP, while back pain was more frequent in children with other disabilities. Comorbid emotional disorders were significantly associated with the non-CP disabilities. Children who required more than four clinic attendances were more likely to have comorbid anxiety/depression and to be reviewed by multiple specialists.

CONCLUSIONS

Long-term persistent pain in children with DD forms a significant cohort of children requiring tertiary level paediatric pain services. Multisystem comorbidities and emotional disorders predict greater service utilisation. Further research into the effectiveness of multidisciplinary pain teams and interventions in this cohort of children is required.

Drugs for chronic pain in children: a commentary on clinical practice and the absence of evidence

Pediatric chronic pain is widespread, under-recognized and undertreated. Best management usually involves a multimodal approach coordinated by a multidisciplinary team. The present commentary specifically discusses common pharmacological approaches to chronic pain in children, identifies gaps in knowledge and suggests several research directions that would benefit future clinical care.

Mental health disorders and long-term opioid use among adolescents and young adults with chronic pain

PURPOSE

The purpose of this study was to examine the association between mental health disorders and subsequent risk for long-term opioid use among adolescents and young adults presenting with common chronic pain complaints (back pain, neck pain, headache, and arthritis/joint pain).

METHODS

Using claims data from January 1, 2001 to June 30, 2008, we conducted a longitudinal analysis of opioid use patterns among 13-24-year-old subjects presenting with a new episode of chronic pain. Long-term opioid use was defined as receiving >90 days of opioids within a 6-month period with no gap of >30 days in use of opioids in the 18 months after the first qualifying pain diagnosis. Mental health disorders were identified from claims in the 6 months before the first qualifying pain diagnosis.

RESULTS

Fifty-nine thousand seventy-seven youth met criteria for a new episode of chronic pain. Among these youth, 321 (.5%) met criteria for long-term opioid use, and 16,172 (27.4%) had some opioid use. After controlling for demographic and clinical factors, youth with preexisting mental health diagnoses had a 2.4-fold increased risk of subsequently receiving long-term opioids versus no opioids (odds ratio = 2.36, 95% confidence interval = 1.73-3.23) and a 1.8-fold increased likelihood of receiving long-term opioids versus some opioids (odds ratio = 1.83, 95% confidence interval = 1.34-2.50).

CONCLUSIONS

Mental health disorders are associated with increased risk for long-term opioid use among adolescents and emerging young adults. Further study is warranted to examine risks and benefits of long-term opioid use in this population.
