“as to disease, make it a habit of two things- to do good, or at least do no

harm” Hippocrates

RISK BENEFIT

� Risk is the potential loss (an undesirable outcome) resulting from a given action, activity and/ or inaction

Benefit something that has a good effect or promotes well-being.

� Acute pain- Opioids are often very helpful in the treatment of acute pain conditions (trauma/surgery).

� Chronic pain- Opioids can be helpful but there is a lack of evidence for effectiveness and the “evidence for the benefits has remained controversial and insufficient”.

� Federation of State Medical Boards, Model Policy on the Use of Opioid Analgesics in the Treatment of Chronic Pain, July 2013

� Opioids do help in some chronic pain patients.

� A trial of opioid therapy for chronic pain should only be considered after failure of other treatment options.

� Generally, improvement with chronic opioid therapy is about a 30% decrease in pain when they are helpful.

� Medical management of chronic pain claims have been increasing.

� In 2008, 17% of chronic pain cases involved medical management.

� Death from opioid rotation.

� MVA due to prescription opioids.

� Overdose related to non compliance with guidelines.

� Iatrogenic addiction.

� Lack of informed consent.

� Prescription opioids caused 11,499 deaths in 2007, more than cocaine and heroin combined.

� Prescription pain medications are the second most prevalent type of abused drug after marijuanna.

� Admissions to substance abuse treatment programs increased 400% from 1998-2008.

� Prescription drug abuse is the fastest growing drug problem in the U.S.

� In an attempt to better treat patient pain, practitioners have greatly increased their rate of opioid prescribing.

� 1997, drug distribution was 96 mg morphine equivalents per person.

� By 2007, it was 700 mg per person (increase 7 times)

� Many providers under-appreciate the risk of opioids and frequently exaggerate the benefitsof high dose chronic opioid treatment.

� It is critical to define the populations at greatest risk to develop and implement effective interventions.

� Age

� Dose- greater than 100 mg morphine equivalents (ME) per day.

� Patients with underlying lung disease.

� Patients with underlying liver disease.

� Patients with comorbid substance use disorder.

� Patients on benzodiazepines.

� Patients with comorbid mental health disorder.

� Literature shows a consistent increase risk for opioid misuse for younger patients.

� Persons aged 18-30 showed a 4-5 fold increased risk for opioid misuse compared to persons 65 and older(Sullivan, Ballantyne. Arch Intern Med/ Vol 172(#5), Mar 2012:433-4).

� Older patients often have more medical comorbidities, altered pharmacokinetics and pharmacodynamics that can increase their risk.

� Estimated annual overdose rates:

� 0.2% < 20 ME mg day

� 0.7% 50-99 ME mg day

� 1.8% > 100 ME mg day

� 88% of identified OD were non fatal but required hospitalization.

� Higher in patients over 65, history of sub abuse treatment or a history of depression.

� Highest risk after prescription refill of new prescription.

Opioid Prescriptions for Chronic Pain and Overdose (Ann Intern Med, Jan 2010)

� “It is much more important to know what sort of patient has a disease than what sort of disease the patient has.”

� Sir William Osler

� Structured evidence based review of all studies available on the development of abuse/addiction and ADRB in chronic pain patients exposed to COT.

� Abuse/addiction grouping calculated abuse/addiction rate 3.27%

� Preselected for no previous history 0.19%

BIOLOGICAL PSYCHIATRIC

� Age < 45

� Gender

� Family history of prescription drug or ETOH abuse (genetic and environmental)

� Cigarette smoking

� Substance use disorder

� Preadolescent sexual abuse (in females)

� Major psychiatric disorder (eg, personality disorder, anxiety or depressive disorder, biploardisorder)

� Social

� Prior Legal problems

� History of MVA

� Poor family support

� Involvement in a problematic subculture

� Life stressors

� Key principle prior to starting a patient on chronic opioid therapy is determining a patient’s risk of abuse/harm.

� There are a number of validated tools available to help assess a patients risk of opioid abuse.

� Ideally they are simple, validated and identify abuse potential prior to initiating COT.

� Borrowed from infectious disease.

� Impossible for the health care professional to reliably assess the risk of infectivity during an initial assessment of the patient.

� We have to apply an appropriate minimum level of precaution to all patients to reduce the risk of transmission of infection.

� Also, impossible to reliably predict the risk of opioids during a initial assessment so same principles apply.

� 1) Diagnosis with appropriate differential.

� 2) Psychological assessment (risk of addictive disorders)

� 3) Informed consent.

� 4) Treatment agreement.

� 5) Pre and Post intervention assessment of pain level and function.

� 6) Appropriate trial of opioid therapy

� 7) Reassessment of pain score and level of function.

� 8) Regularly assess the “4A’S” of pain medicine (analgesia, activity, adverse effects, aberrant behavior).
