Flipping the Pain Care Model: A Sociopsychobiological Approach to High-Value Chronic Pain Care

OBJECTIVE

Much of the pain care in the United States is costly and associated with limited benefits and significant harms, representing a crisis of value. We explore the current factors that lead to low-value pain care within the United States and provide an alternate model for pain care, as well as an implementation example for this model that is expected to produce high-value pain care.

METHODS

From the perspective of aiming for high-value care (defined as care that maximizes clinical benefit while minimizing harm and cost), we describe the current evidence practice gap (EPG) for pain care in the United States, which has developed as current clinical care diverges from existing evidence. A discussion of the biomedical, biopsychosocial, and sociopsychobiological (SPB) models of pain care is used to elucidate the origins of the current EPG and the unconscious factors that perpetuate pain care systems despite poor results.

RESULTS

An interprofessional pain team within the Veterans Health Administration is described as an example of a pain care system that has been designed to deliver high-value pain care and close the EPG by implementing the SPB model.

CONCLUSIONS

Adopting and implementing a sociopsychobiological model may be an effective approach to address the current evidence practice gap and deliver high-value pain care in the United States. The Phoenix VA Health Care System's Chronic Pain Wellness Center may serve as a template for providing high-value, evidence-based pain care for patients with high-impact chronic pain who also have medical, mental health, and opioid use disorder comorbidities.

Circadian rhythms: a regulator of gastrointestinal health and dysfunction

Circadian rhythms regulate much of gastrointestinal physiology including cell proliferation, motility, digestion, absorption, and electrolyte balance. Disruption of circadian rhythms can have adverse consequences including the promotion of and/or exacerbation of a wide variety of gastrointestinal disorders and diseases. Areas covered: In this review, we evaluate some of the many gastrointestinal functions that are regulated by circadian rhythms and how dysregulation of these functions may contribute to disease. This review also discusses some common gastrointestinal disorders that are known to be influenced by circadian rhythms as well as speculation about the mechanisms by which circadian rhythm disruption promotes dysfunction and disease pathogenesis. We discuss how knowledge of circadian rhythms and the advent of chrono-nutrition, chrono-pharmacology, and chrono-therapeutics might influence clinical practice. Expert opinion: As our knowledge of circadian biology increases, it may be possible to incorporate strategies that take advantage of circadian rhythms and chronotherapy to prevent and/or treat disease.

Overlaps in pharmacology for the treatment of chronic pain and mental health disorders

There is significant overlap in the pharmacological management of pain and psychological disorders. Appropriate treatment of patients' comorbid psychological disorders, including sleep disturbances often leads to an improvement in reported pain intensity. The three first line agents for neuropathic pain include tricyclic antidepressants and serotonin norepinephrine reuptake inhibitors which are medications originally developed as antidepressants. The other first line medication for chronic neuropathic pain are anticonvulsant medications initially brought to the market-place for the treatment of epilepsy and are also now being used for the treatment of anxiety disorders and substance withdrawal symptoms. The efficacy of opioids for chronic pain is contentious, but it is agreed that the patients at highest risk for opioid misuse and addiction are patients with underlying psychological disorders who use opioids for their euphoric effects. Similarly, benzodiazepines may present a problem in patients with chronic pain, as up to one third of patients with pain are concomitantly prescribed benzodiazepines, and when combined with other sedating analgesic medications they put patients at increased risk for adverse events and polysubstance misuse. Finally, there is growing evidence for the efficacy of cannabis for treating neuropathic pain, but the consumption of cannabis has been associated with increased risk of psychosis in adolescents, and may be associated with an increased risk for developing bipolar disorder and anxiety disorders. The use of cannabis is associated with an increased risk of substance misuse in both adolescents and adults. In this narrative review, we examine the evidence for the use of several medications used for the treatment of both pain and psychological disorders, and their proposed mechanisms of action, in addition to special concerns for patients with comorbid pain and psychological disorders.

Sleep Disturbances Are Commonly Reported Among Patients Presenting to a Gastroenterology Clinic

BACKGROUND

Poor sleep quality is common among patients with gastrointestinal (GI) disorders. However, few studies have assessed the presence of insomnia or reported circadian preferences and none have directly compared sleep between common GI conditions.

AIMS

To compare clinical sleep characteristics in patients presenting to a tertiary care GI clinic for irritable bowel syndrome (IBS), functional dyspepsia (FD), inflammatory bowel disease (IBD), gastroesophageal reflux disease (GERD), and celiac disease (CD).

METHODS

Validated sleep measures were administered to consecutive patients if they were diagnosed with IBS, IBD in clinical remission, CD, FD, or GERD. Healthy Controls (HCs) with no reported GI diagnoses or symptoms were also recruited.

RESULTS

A total of 212 eligible respondents completed this survey, 161 GI clinic patients (IBS (n = 48), GERD (n = 29), IBD in clinical remission (n = 44), CD (n = 40)), and 41 HCs. Only, 10 respondents had a diagnosis of FD, and these were excluded. The IBS group had the highest frequency of poor sleep (72%) followed by CD (61%), GERD (60%), IBD (54%), and HC (39%). IBS patients also had the highest frequency of clinical insomnia (51%), followed by GERD (37%), CD (35%), IBD (27%), and HC (18%). 40% of IBS patients reported taking sleep medications at least once per week, compared to 32% of GERD, 23% IBD, 13% CD, and 15% HC.

CONCLUSIONS

Patients presenting to a tertiary care GI clinic report poorer sleep than healthy controls. In general, patients with IBS report the highest rates of sleep difficulties compared to patients with other diagnoses.
