In 1994, the Board reviewed the operation and effectiveness of the three main international drug control treaties and highlighted in its report the principal areas where the treaty provisions had not been wholly effective or adequate.6 Among the identified shortcomings was the fact 1.

At the same time, the Board voiced its concern over drugs continues to be indispensable for the relief of pain and the easy availability of psychotropic substances, in particular suffering and that adequate provision must be made to ensure 2 their indiscriminate and excessive use in many countries and the availability of narcotic drugs for such purposes. Guided their diversion into illicit channels as a result of inadequate by a similar principle, States recognized in the Convention control measures. on Psychotropic Substances of 1971 that the availability of psychotropic substances for medical and scientific purposes 3 should not be unduly restricted.

In adopting such aims, Governments were motivated by two complementary humanitarian considerations, namely the The significance of controlled drugs in alleviating need to provide optimal help and relief for pain and suffering pain and suffering and the need to protect the individual and society from drug dependence and its detrimental consequences.4 4.

    What We Mean When We Talk About Suffering—and Why Eric Cassell Should Not Have the Last Word Tyler Tate, Robert Pearlman Perspectives in Biology and Medicine, Volume 62, Number 1, Winter 2019, pp. 95-110 (Article) Published by Johns Hopkins University Press For additional information about this article https://muse.jhu.edu/article/722412 Access provided at 26 Apr 2019 00:52 GMT from University of Washington @ Seattle What We Mean When We Talk About Suffering—and Why Eric Cassell Should Not Have the Last Word Tyler Tate* and Robert Pearlman† ABSTRACT This paper analyzes the phenomenon of suffering and its relation- ship to medical practice by focusing on the paradigmatic work of Eric Cassell. First, it explains Cassell’s influential model of suffering. Second, it surveys various critiques of Cassell. Next it outlines the authors’ concerns with Cassell’s model: it is aggressive, obscure, and fails to capture important features of the suffering experience. Finally, the authors propose a conceptual framework to help clarify the distinctive nature of sub- jective patient suffering. This framework contains two necessary conditions: (1) a loss of a person’s sense of self, and (2) a negative affective experience. The authors suggest how this framework can be used in the medical encounter to promote clinician-patient communication and the relief of suffering. *Center for Ethics in Health Care and School of Medicine, Oregon Health and Science University, Portland. †National Center for Ethics in Health Care, Washington, DC, and School of Medicine, University of Washington, Seattle.

  • AAFP Chronic Pain Toolkit
    AAFP Chronic Pain Toolkit PAIN ASSESSMENT | Section 1 OVERVIEW Assessment of chronic pain should be multidimensional. Consideration should be given to several domains, including the physiological features of pain and its contributing factors, with physicians and other clinicians assessing patients for function, quality of life, mental health, and emotional health. In addition to a complete medical and medication history typically obtained at an office visit, documentation should be obtained about pain intensity, location, duration, and factors that aggravate or alleviate pain. A physical exam should include musculoskeletal and neurological components, as appropriate. Diagnostic testing and imaging may also be considered for some types of chronic pain. Many organizations, including the AAFP, recommend against imaging for low back pain within the first six weeks of treatment unless there are reasons for the imaging. These reasons may include concerns of underlying conditions, such as severe or progressive neurological deficits, or if osteomyelitis is suspected.1 Periodic reassessments of chronic pain and treatment should focus on evaluating improvements in physical health; mental and emotional health; progress towards functional treatment goals; and effectiveness and tolerability of medications for chronic pain treatment. Currently, there are no universally adopted guidelines or recommendations for assessment of chronic pain. The use of appropriate assessment tools can assist in diagnostic assessment, management, reassessment, and monitoring of treatment effects. Multiple tools are available, with many embedded in electronic health record (EHR) systems. Pain Assessment Tools The table on the next page includes selected tools for pain assessment included in this toolkit, along with links and reference to additional tools. Assessments about other relevant domains are covered in Functional and Other Assessments (Section 2).

Ethics: Should people be taught to forecast more accurately? 10 Conclusions 12 References 13 Examining Affective Forecasting and its Practical and Ethical Implications Introduction Emotions are important in guiding thoughts and behaviour to the extent that they are used as heuristics (Slovic, Finucane, Peters & MacGregor, 2007), and are crucial in decision-making (Anderson, 2003). Affective forecasting (AFing) concerns an individual’s judgemental prediction of their or another’s future emotional reactions to events. It is suggested that “affective forecasts are among the guiding stars by which people chart their life courses and steer themselves into the future” (Gilbert, Pinel, Wilson, Blumberg & Wheatley, 1998; p.617), as our expected reactions to emotional events can assist in avoiding or approaching certain possibilities. We can say with certainty that we will prefer good experiences over bad (ibid); however AFing research demonstrates that humans are poor predictors of their emotional states, regularly overestimating their reactions. Further investigation of these findings shows that they may have critical implications outside of psychology. If emotions are so influential on behaviour, why are people poor at AFing? Furthermore, can and should individuals be assisted in forecasting their emotions? These issues, along with the function of AFing in practical applications, are to be considered and evaluated.

This information or content and conclusions are those of the author and should not be construed as the official position or policy of, nor should any endorsements be inferred by HRSA, HHS or the U.S. Government. Disclosures Stephen Wyatt has nothing to disclose Objectives • Understand the complexities of treating acute and chronic pain in patients with opioid use disorder (OUD). • Understand the various approaches to treating the OUD patient on an agonist medication for acute or chronic pain. • Understand how acute and chronic pain can be treated when the OUD patient is on an antagonist medication. Speaker Notes: The general Outline of the module is to first address the difficulties surrounding treating pain in the opioid dependent patient. Then to address the ways that patients with pain can be approached on either an agonist of antagonist opioid use disorder treatment. Pain and Substance Use Disorder • Potential for mutual mistrust: – Provider • drug seeking • dependency/intolerance • fear – Patient • lack of empathy • avoidance • fear Speaker Notes: It is the provider that needs to be well educated and skillful in working with this population. Through a better understanding of opioid use disorders as a disease, the prejudice surrounding the encounter with the patient may be reduced.

GENERAL STATEMENT of PURPOSE To establish a standard for routine assessment, reassessment and documentation of pain as appropriate to the patient’s condition and treatment regimen. POLICY 1. Patients are screened and assessed for pain based upon clinical presentation, services sought, and in accordance with the care, treatment, and services provided. Facility personnel use methods to assess pain that are consistent with the patient’s age, condition, and ability to understand. 2. If the patient reports pain to a health care worker other than a licensed health care provider, the health care worker will escalate the report of pain to a licensed health care provider for assessment. 3. Pain assessment performed by health care providers will address individual, cultural, spiritual, and language differences. Pain measurement scales are available in various languages and, if necessary, access to a medical interpreter will be provided to assist in the evaluation of the patient’s pain. 4. The patient’s self-report of pain is considered the “gold standard.” For those patients who are unable to communicate the health care provider will assess pain by using the appropriate pain Measurement Scale.
