Learning objectives
At the end of the workshop you will be able to:
• Consider the important principles of pain and pain management
• Use validated tools to assist in assessing patients pain
• Outline strategies to manage pain with your patients
• Discuss pain medicines with your patients
What is pain?
• A message to the brain, pain is a ’whole body’ experience and involves both the mind and the body
• Usually a protective mechanism to warn us to be more careful of our bodies
• It hurts and may cause suffering or distress
• Different for different people: it is whatever the person says hurts
Types of pain
• Acute pain can be important for the body to tell the brain that there is something wrong and help to avoid harm.
• Chronic pain is pain that goes on for a long time. It needs regular assessment and a different approach to treatment.
Chronic pain impacts on the whole person and their community
Ask your patients about any changes that have happened in their lives since their ongoing pain started.
For example:
• How are you sleeping?
• Are you feeling worried or sad?
• Are you still visiting friends or relatives?
• Are you eating well?
Things to talk about:• How pain is affecting their life
• Where the pain is, how bad the pain is
• How long they have had the pain
• What medicines they are taking for the pain (and any other conditions)
• How the pain has affected them and their family
• If they have any other problems or worries
• Make sure people understand that it may not be possible to be pain-free at all times
• Anticipation of pain
How do we assess painAsk the patient:
• To describe their pain
• Rate their pain (use the faces scale based on how they perform everyday activities)
• What made the pain worse or better
Observe the person’s body language (how freely do they move).
Talk with the person about how they feel, and how it affects their everyday life
Talk with their family when appropriate
Make sure people understand that it may not be possible to be pain-free at all times
REMINDER:
Use the same pain assessment tool to keep a detailed record of the patients’ pain changes in the clinic notes.
Managing chronic pain
Treatment goals:
• To improve the level of activity
• To modify thoughts about pain and suffering
• To promote self-management
• To relieve pain to a tolerable level
Managing chronic pain
Tips on helping people to exercise
• Educate patients that there is a difference between ‘hurt’ and ‘harm’ when you have chronic pain. Avoiding physical activity can make their pain seem worse over time.
• Encourage patients to talk to their family and friends and not isolate themselves. Also get a family member or friend involved as their ‘exercise buddy’.
• You may wish to suggest some exercises to try e.g. walking, swimming, gentle stretching exercises. Remember to start slow with exercise as they may feel some discomfort initially, especially if they have been inactive for a long time.
Medicines
Key points:
• Use a step-wise approach to introduce pain medicines (analgesics)
• Prescribe regular doses of analgesics
• Plan a trial period with clear and specific instructions
• Review the effects on regular basis eg may need more frequent review for new medicines or when dose changes
