Chronic pain in the 11th revision of the International Classification of Diseases: users' questions answered

The new chronic pain MG30 category and diagnostic specificity in quality registries-problems and suggested solutions with special reference to Swedish Quality Registry for Pain rehabilitation (SQRP)

The Swedish Quality Registry for Pain rehabilitation (SQRP) is a well-established clinical registry for adult patients with complex chronic pain conditions. SQRP registers patient-reported outcome measures from a majority of specialist chronic pain units/departments in Sweden. Up to four International Classification of Diseases version 10 (ICD-10) diagnoses can be registered in SQRP. The aim of the paper is to describe how we envision the new chronic pain category MG30 in ICD-11 can be used in SQRP. We envision that the first diagnosis in SQRP shall always be a MG30 diagnosis, which will ensure broad implementation of ICD-11 in Swedish pain care. However, at first glance, there seems to be specificity problems with ICD-11 codes that might impair their useability in SQRP or other registries. But ICD-11 offers more than meets the eye. First, the entries at the level of the so-called foundational layer have unique resource identifiers (URI) that can be used to enhance specificity. Second, ICD-11 contains numerous extension codes that can be combined with the MG30 codes - for instance, concerning the anatomical location of pain. Third, to enrich the description of the clinical concept at hand, it is possible to create clusters of stem codes. These three options are briefly discussed. We conclude that the full potential of the MG30 category can be better exploited in registries such as SQRP if foundational codes, extension codes, and/or clustering of stem codes are used to enhance diagnostic specificity.

Pain as a disease in the new International Classification of Diseases (ICD-11): Latin American expert consensus

Aims: Pain diagnoses in the 10th version of the International Classification of Diseases (ICD-10) did not adequately support the current management of pain. Therefore, we aimed to review the new 11th revision (ICD-11) in order to analyze its usefulness for the management, coding, research and education of chronic pain from a Latin American perspective. Methods: The Latin American Federation of Associations for the Study of Pain convened a meeting of pain experts in Lima, Peru. Pain specialists from 14 Latin American countries attended the consensus meeting. Results: In ICD-11, chronic pain is defined as pain that persists or recurs longer than 3 months and is subdivided into seven categories: chronic primary pain and six types of chronic secondary pain. Chronic primary pain is now considered a disease in itself, and not a mere symptom of an underlying disease. Conclusion: The novel definition and classification of chronic pain in ICD-11 is helpful for better medical care, research and health statistics. ICD-11 will improve chronic pain management in Latin American countries, for both the pain specialist and the primary care physician.

The invisible cost of pain management by the current International Classification of Diseases coding system: a study in a tertiary care inpatient setting

ABSTRACT

The International Classification of Diseases ( ICD ) is applied worldwide for public health data collection among other use cases. However, the current version of the ICD ( ICD-10 ), to which the reimbursement system is linked in many countries, does not represent chronic pain properly. This study aims to compare the ICD-10 with the ICD-11 in hospitalized patients in terms of specificity, clinical utility, and reimbursement for pain management. The medical records of hospitalized patients consulted for pain management at Siriraj Hospital, Thailand, were reviewed, and all pain-related diagnoses were coded into ICD-10 and ICD-11 . The data of 397 patients showed unspecified pain was coded 78% in the ICD-10 and only 0.5% in the ICD-11 version. The difference gap in the proportion of unspecified pain between the 2 versions is wider than in the outpatient setting. The 3 most common codes for ICD-10 were other chronic pain, low back pain, and pain in limb. The 3 most common codes for ICD-11 were chronic cancer pain, chronic peripheral neuropathic pain, and chronic secondary musculoskeletal pain. As in many other countries, no pain-related ICD-10 codes were coded for routine reimbursement. The simulated reimbursement fee remained the same when adding 397 pain-related codings, even if the cost of pain management, such as cost of labor, existed. Compared with the ICD-10 version, the ICD-11 is more specific and makes pain diagnoses more visible. Thus, shifting from ICD-10 to ICD-11 has the potential to improve both the quality of care and the reimbursement for pain management.

Nurse Practitioners in a Canadian Pediatric Rehabilitation Hospital: A Description of Roles and Scope of Practice

The nurse practitioner role is strongly suited to meet the needs of children with complex developmental conditions in pediatric rehabilitation settings as they have a unique combination of clinical expertise. To meet the increasing demands in a large Canadian pediatric rehabilitation hospital, the NP role was implemented in several clinical program settings to improve access to care. This paper describes the contributions of NPs to nine specialized inpatient and outpatient programs in NP-led, collaborative NP and physician or interagency care team models of practice. The initial challenges of role implementation and implications for NP practice, research and leadership are discussed.

Chronic Pain in the ICD-11: New Diagnoses That Clinical Psychologists Should Know About

Background

In the 10th revision of the International Classification of Diseases and Related Health Problems (ICD-10), chronic pain was not represented adequately. Pain was left undefined and not recognized as a biopsychosocial phenomenon. Instead, a flawed dualism between psychological and somatic factors was implied. Individual diagnoses were ill-defined and scattered randomly through different chapters. Many patients received diagnoses in remainder categories devoid of meaningful clinical information.

Method

The International Association for the Study of Pain launched a Task Force to improve the diagnoses for the 11th revision of the ICD and this international expert team worked from 2013-2019 in cooperation with the WHO to develop a consensus based on available evidence and to improve the diagnoses.

Results

A new chapter on chronic pain was created with a biopsychosocial definition of pain. Chronic pain was operationalized as pain that persists or recurs longer than three months and subdivided into seven categories: Chronic primary pain and six types of chronic secondary pain. All diagnoses were based on explicit operationalized criteria. Optional extension codes allow coding pain-related parameters and the presence of psychosocial aspects together with each pain diagnosis.

Conclusion

First empirical studies demonstrated the integrity of the categories, the reliability, clinical utility, international applicability and superiority over the ICD-10. To improve reliability and ease of diagnosis, a classification algorithm is available. Clinical psychologists and other clinicians working with people with chronic pain should watch the national implementation strategies and advocate for multimodal and interdisciplinary treatments and adequate reimbursement for all providers involved.

Psychopathological and neuropsychological disorders associated with chronic primary visceral pain: Systematic review

The World Health Organization (WHO), in its last review of its International Classification of Diseases, established a new classification for chronic pain. Among the principal categories, of particular interest is chronic primary pain as a new type of diagnosis in those cases in which the etiology of the disease is not clear, being termed as chronic primary visceral pain when it is situated in the thorax, abdomen, or pelvis. Due to the novelty of the term, the objective of the systematic review was to examine the psychopathological and neuropsychological disorders associated with chronic primary visceral pain. We carried out a search of the scientific literature following the PRISMA directives using the Pubmed, Medline, PsycInfo and Scopus databases. A total of 33 articles were selected after applying the inclusion and exclusion criteria. The analysis of the studies showed that most persons with chronic primary visceral pain suffer from at least one psychological disorder; the most prevalent being anxiety, depressive or somatoform disorders. The most frequent psychopathological symptoms are anxiety, depression and somatization. Similarly, the findings are insufficient to determine the existence of deficits in the domains of executive functioning, memory and intelligence. However, the existence of attention biases does seem to be clear. This review supposes a starting point for conceptualizing chronic primary visceral pain. It is necessary to continue further research so as to obtain a better understanding of this pathology and the disorders associated.

Pediatric chronic post-surgical pain prevalence, pain scores, and quality-of-life: results of an exploratory patient survey at a single-center tertiary care children's hospital

PURPOSE

Twenty percent of children may develop chronic post-surgical pain (CPSP), but studies investigating pediatric CPSP are limited in scope. In an exploratory patient survey, we sought to assess CPSP prevalence among children of all ages, across a wide range of surgeries, and over an extended period of time after surgery.

METHODS

We conducted a survey study, including patients < 19 years of age at the time of their surgery at a single-center, quaternary care academic pediatric hospital. Pediatric patients who underwent surgery from May 2014 to August 2019 were included. Via electronic survey, patients/caregivers were asked whether the child had any pain related to their last surgery at the pediatric hospital. Patients/caregivers who answered yes were asked 11 additional questions about the child's pain and pain-related quality of life. The primary outcome was CPSP prevalence; secondary outcomes were pain scores, quality-of-life scores, and the associations of CPSP with time since surgery, preoperative pain, and patient age.

RESULTS

The response rate of completed surveys was 4.0%. 30% of respondents reported CPSP; the median pain score was 4.0 on an 11 point scale (0 to 10). Responses to quality of life questions indicated CPSP negatively impacted many children's lives. Preoperative pain was associated with an odds ratio for CPSP of 1.09 [95% confidence interval (CI): 0.58, 2.04], each year after surgery with an odds ratio of 0.94 (95% CI 0.80, 1.10), and each year of age at surgery with an odds ratio of 1.07 (95% CI 1.02, 1.12).

CONCLUSION

While limited by a low response rate, results from this exploratory survey suggest that CPSP is a considerable problem for children who undergo surgery across many specialties, with marked effects on patient well-being even years after surgery.
