Pain management

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 pain

Ask 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

REMINDER: 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 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.

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
