Summary
The Current Opioid Misuse Measure (COMM) is a new tool to help clinicians monitor opioid misuse in chronic pain patients. This validated self-report measure shows promise for tracking aberrant drug-related behaviors.
Area of Science:
- Pain Management
- Addiction Medicine
- Psychometrics
Background:
- Monitoring aberrant medication-related behaviors is crucial for chronic pain patients on opioid therapy.
- Opioid misuse poses significant risks, necessitating reliable assessment tools.
Purpose of the Study:
- To develop and validate the Current Opioid Misuse Measure (COMM) for assessing aberrant behaviors in patients on long-term opioid therapy.
- To create a brief, self-report instrument for clinicians to monitor opioid misuse.
Main Methods:
- An initial pool of 177 items was generated with expert input and refined through concept mapping.
- A 40-item alpha version was empirically evaluated with 227 chronic non-cancer pain patients.
- Reliability, validity, and clinical utility were assessed using various psychometric and clinical measures, including toxicology screening and physician ratings.
Main Results:
- A 17-item COMM demonstrated excellent internal consistency and test-retest reliability.
- ROC curve analysis established appropriate cutoff scores with good sensitivity and specificity.
- The measure showed promise in capturing changes in patient status over a three-month period.
Conclusions:
- The Current Opioid Misuse Measure (COMM) is a promising brief, self-report tool for assessing current aberrant drug-related behaviors in patients on opioid therapy.
- Further cross-validation and replication studies are warranted to confirm these preliminary findings.

01:25Analgesia and Pain Management
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
01:15Opioid Analgesics: Synthetic and Semisynthetic Opioids
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
01:15Drug Abuse and Addiction: Pharmacological Phenomena
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
01:20Opioid Analgesics: Morphine and Other Natural Cogeners
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...
01:22Opioid Receptors: Overview
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2, D-Pen5]-enkephalin or DPDPE for...
01:24Substance Use Disorders Affecting Sleep
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
