Simple approach to PAIN

Pain is ubiquitous in medicine and often overlooked. Despite a thorough definition, 'an unpleasant, sensory and emotional experience associated with actual or potential tissue damage', it is impossible to really understand someones pain unless you have felt it yourself. It is a highly diffuse symptom with a massive impact on patient well being and quality of life (it may even be much more diffuse than believed). It is an all encompassing entity which if you take Dame Cicely Saunders concept of 'total pain' concerns not only physical aspects but also social, spiritual and emotional aspects. 

If you take cancer pain, it is the most frequent presenting symptom and present overall in the majority of cancer patients. Shockingly pain is reported in a minority of cancer medical records, it would seem that many oncologists dont assess pain, probably fixating on battling the cancer itself (one of the toughest battles in medicine to add). Pain should be considered a disease entity itself and if it is properly assessed, addressed and treated, it could go a long way to enhance patient quality of life.

Here is a simple approach to pain you should consider whenever a patient says they are in pain:

First ASSESSMENT:

ABCDE 

A is for Ask: Ask about the pain: use the OPQRST approach:

• Onset
• Provoking factors 
• Quality of pain
• Region and Radiation of pain
• Severity 
• Timing and history 

When assessing severity use the NRS or VAS technique; "on a scale of zero to ten, where ten is the worst pain imaginable and zero is no pain, how would you describe your pain severity" (this is NRS, VAS is the application of a mark on a 10cm line to indicate pain severity in the same way).

score of 1-3 is mild  (VAS would be 1-3cm)

score of 4-6 is moderate pain (4-6cm mark)

score of 7-10 is severe pain (7-10cm mark)

One really important thing to think about after you have taken a thorough history is "what is causing the pain?"

B is for Believe the patient, don't dismiss them.

C is for Control: choose and appropriate pain control method, best way to apparoch pain treatment is with the WHO pain treatment ladder, which can be applied to all pain and not just cancer pain. move up the steps if pain is not well managed or still present.

• 1st step: PARACETOMOL (to treat mild pain)
• 2nd step: WEAK OPIOIDS (for example tramadol or codiene, these are opioids with a ceiling effect where inceasing drug dosgae will not improve effect from a certain point)
• 3rd step: STRONG OPIOIDS (consider for mod-severe pain). (for all opioids "start low and go slow"
• at any point you can add adjuvants to the ladder: NSAIDS, corticosteriods, antidepressants, anticonvulsants, benzodiazepines.

D is for Deliver pain control in a timely manner

E is for Empower the patient in pain control, patient education is so important. 

Second MANAGEMENT:

The four A's:

• Optimize ANALGESIA
• Optimize ACTIVITIES of daily living
• Minimize ADVERSE EFFECTS due to treatment
• AVOID unnecessary  drug taking

Third REASSESSMENT:

Simply, reassess often!
