Clinical / Education / Audit / Research Links with Outreach Team Palliative Care Team Ward based link nurses School of Nursing Clinical facilitators + educators Other nurse specialists Regional and National Specialists in Pain Definition of Pain ‘Pain is whatever the experiencing person says it is, existing whenever the experiencing person says it does’ McCaffrey(1968) Definition of Pain ‘Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Pain is always subjective……always unpleasant and therefore also an emotional experience.’ International Association for the Study Pain (1979) Why Treat Pain? Humanitarian Reasons Clinical Effects of Pain Reduces Stress Response Patient Satisfaction Promote Early Discharge How Do We Feel Pain? Two Major Types of Pain Nociceptive: pain due to tissue damage Neuropathic:pain due to injury of nerve pathway - painful sensations are carried from the site of injury to the brain - treatment will depend on type of pain Acute Pain Helps diagnose illness by acting as a warning mechanism - therefore is a symptom From trauma often imposes limitations, which can prevent aggravation of an injury In post-operative period serves no useful purpose and can be detrimental to the recovery of the patient Recent studies/surveys indicate that pain control still remains an inconsistent affair Chronic Pain Untreated Acute Pain can become Chronic Pain Chronic Pain Pain that persists beyond the expected healing time Not simply a prolonged duration of acute pain. Biological changes in central nervous system. Adaptation of autonomic nervous system. Complex Pain that is prolonged in nature, due to known reasons or absence of evident tissue damage. Complex interplay of biological & psychological factors. 7.5 million pain sufferers in UK Cancer Pain Cancer is a dynamic disorder and patients may experience Acute as well as Chronic pain due to further tissue damage Pain of varied duration/commonly progressive Pain may be associated with symptoms which signal deterioration eg weight loss, anorexia, physical dependence, lack of sleep Realization of dying may result in “overwhelming pain” that is difficult to describe and to assess ACUTE CHRONIC Transient Warning mechanism Usually decreases at around 48hrs Start at top of medication ladder Persistent No useful purpose Tends to increase as time goes on Starts at bottom of medication ladder Pain Assessment Advantages Provides patients with an opportunity to express their pain Conveys genuine interest & concern about their pain Gives patients an active role in their pain management Can provide documented evidence of the efficacy or failure of drugs / treatments Pain Assessment When Initially to understand the pain & develop a care plan Immediately following surgery / procedures Prior to & following administration of analgesia / treatments At a report in change of description, location or intensity of pain Deep breathing / coughing / moving limb etc Pain Assessment – What You Need to Know Location Description Duration Pain Intensity ?
