Objectives • Understand the major categories of pain • Implement the WHO pain ladder to manage patients with pain • Perform safe and effective opiate dosing, escalation, and conversions
Why Pain? • Extremely common and undertreated • 50% of community dwelling older persons • Only 40% of oncology and 30% of hip fracture patients report “adequate” pain control • Education in pain assessment and management mandated by ACGME/RCCs and Joint Commission • Undertreated pain leads to functional decline, prolonged length of stay, increased healthcare utilization
Bedside Assessment of Pain Patient centered approach is the key • ASK the patient, regardless of mental status • Identify preferred pain terminology • Hurting, aching, stabbing, discomfort, soreness • Type: visceral, nocioceptive, neuropathic • Functional impact: How is their life changed? • Use a pain scale that works for the patient • Physiologic measures (eg, HR, BP) not reliable indicators
Pain in non-verbal pts • Unique pain signature – • Use baseline behavior as frame of reference • Pain can cause hypo- or hyper-activity • Ask caregivers how they know when pt is in pain • Possible indicators • Facial expression: frown, blinking, sad/frightened • Vocalizations: grunting, calling out, noisy breathing • Movements: rigid, tense, fidgeting, resistance to being moved, pacing
Managing Pain • WHO pain ladder: • Non-opioids • Adjuvants • Opioids
Step 1 - mild to moderate Pain • Non-opioids • APAP • NSAIDs • COX-2 inhibitors • Adjuvants • Topicals – capsaicin cream, lidoderm patch • Anticonvulsants: GABA-nergics • Antidepressants: Cymbalta, tricyclics, SNRIs • Steroids • Non-medication: massage, TENS, PT/OT
Step 2- moderate Pain • Mild opioids • Codeine: GI upset common • Hydrocodone (Vicodin): no paper Rx needed • Oxycodone (Percocet): actually more potent than morphine, reason for low doses with APAP • Opioid-like • Tramadol: analgesia ~ same as T3; max 200 mg/day in elderly
Step 3- Severe Pain Strong Opioids • Morphine • Oxycodone • Hydromorphone (Dilaudid) • Fentanyl • Oxymorphone (Opana, Numorphan) • Methadone
Avoid • Meperidine (Demerol) • Pentazocine (Talwin) • Combination with antihistamine (Vistaril)
Morphine Equianalgesia • Key to dosing and changing opiods • Use calculators Conversion: http://www.epocrates.com/products/medtools/opioidanalgesicconverter.html
Dosing • Load • Start low, short-acting: 2-5 mg PO morphine equivalent (~ 1 Percocet q 4 hr) • Dose q peak: • po, pr ~ 1 hr • SC, IM ~ 30 min • IV ~ 6-15 min • Regular dosing, not “prn” • Re-eval in 4 hrs
Escalating Doses • Use percentage increase irrespective of starting dose • Mild-mod pain: increase by 25 - 50% • Severe: increase by 50 - 100% • Frequency of escalation: • Short-acting, single agent – q 2 hr • Long-acting – every 24 hr • Fentanyl patch – q 72 hr • Methadone – every 4-7 days
Break-through Pain • Use immediate release opioids only • Start: 10% of total 24 hr dose or 33% of one ER dose • Frequency: offer after peak effect • PO/ PR - ~ 1 hr • SC/IM ~ 30 min • IV ~ q10-15 min
