2Program Objectives
- At the end of this program participants will be
better able to - Screen for substance abuse
- Assess the severity of a patients involvement
with alcohol or illicit drugs - Determine the legitimacy of a patients request
for opioid analgesics - Justify and document the decision to prescribe or
refuse to prescribe CDS
3Lawnmower Addict
L.A. is a 42 Y.O. male who broke his ankle while
mowing wet grass across an incline. After several
surgical attempts including failed pinning
operations, his foot is rotated 60 degrees out of
alignment and he has chronic pain. Prior to this
injury L.A. had a history of opioid addiction. He
states that he is committed to recovery and
participates in 12-step N.A. meetings but he
abused his last oxycodone prescription and
experienced a relapse. His goal is to achieve
pain relief without relapse to opioid abuse.
4Enduring pain to avoid relapse
- E.P. is a 40 y.o. married male with 4 children,
He has been in opioid addiction recovery for over
9 years. I received a tearful midnight call from
his wife stating the E.P. was lying in bed in a
fetal position, moaning in pain and refusing to
take opioid analgesics after incurring a back
injury while wrestling with his son who is a star
member of the high school wrestling team. His
goal is to never relapse to active opioid
addiction.
5Scope of the Public Health Problem
- An estimated 2.4 million people have used heroin
at some time in their lives - (NHSDA, 1998)
- During 1996 through 1998, an estimated 471,000
persons used heroin for the first time. Of them,
25 were under age 18 and another 47 were age 18
- 25 (NHSDA, 1999)

7What about abuse?
- According to the National Institute on Drug Abuse
(NIDA), in 1999 Four million Americans reported
current use of prescription drugs for non-medical
purposes - The most dramatic increases were found among the
12 to 25 year olds - Oxycontin and Ritalin were among the most cited
abused medications

10Narcotic Abuse Taxes ED Resources
- In 2001 there were an estimated 90,232 ED visits,
a 117 increase since 1994 - Dependence was the most frequently mentioned
motive for abuse (44 of cases) - Between 2000 and 2001 Oxycodone mentions
increased 70 and accounted for 53.7 of the
overall increase in narcotic abuse cases during
that year.

12Access to treatment is limited
- Of the estimated 810,000 opioid dependent persons
in the U.S. only 170,000 maintenance treatment
slots exist.
13The Journey Matters
14Therapeutic drug use
- Drug use to treat or diagnose illness. Almost
everyone has taken a drug at one time or another
because they were sick. - A direct and reliable drug effect is expected.
Antibiotics kill bacteria regardless of the sick
persons belief in the medicine. The drug is a
known entity. - There are rules. The prescription tells what to
take, how much to take, and when to take it. A
person who violates the rules must own the
consequences.
15Social Drug Use
- Drugs are used to increase social interactions.
- Rules are vague or non-existent.
- Drug supply is uncertain
- Most cases of addiction result from social drug
use that gets out of control.
16A Basic Distinction
- High seeking Pain relief seeking
- Because 6 to 15 of the U.S. population abuses
drugs, the history of pain management is marked
by the undertreatment of pain in the other 85
to 94. - Passik SD quoted in Gilson AM and Joranson DE
(2002) U.S. Policies Relevant to the Prescribing
of Opioid Analgesics for the Treatment of Pain in
Patients with Addiction Disease Clinical Journal
of Pain 18S91-S98. available at
http//www.medsch.wisc.edu/painpolicy/
17Pain Statistics
- Most common reason that people seek medical care
- 50 million Americans are partially or totally
disabled due to pain - Annual cost to U.S. society estimated to exceed
100 billion - 50-80 of patients with pain report that their
pain is inadequately managed - Risk of undertreatment is increased among those
with a history of substance abuse
18Addiction Defined
- Addiction is compulsive use with loss of control
and continued use despite adverse consequences.
19Elements of Compulsivity
- Constant thought of drug acquisition
- Anticipation of opportunities to use
- Defer other priorities of life
- Unable to resist desire to use
20Aspects of Loss of Control
- Inability to use in moderation consistently
- Easier to abstain completely
- Frequent episodes of excessive use
21Continued use despite problems
- Loss associated with use
- Multiple crisis not seen as drug-related
- Sincere promises to self and others to quit
22Signs of Psychological Dependence
- Carrying Drugs
- Using Drugs alone
- Stockpiling Drugs
- Concern over supply
- Changing friends
- Finding excuses to use
- Using at inappropriate times
- Willingness to take increasing risks

25DSM IV Substance Dependence
- 3 of following in 12 month period
- Tolerance
- Withdrawal
- Difficulty cutting down (loss of control)
- Time spent drug seeking (compulsive use)
- Decrease in activities
- Continued use despite knowledge of persistent
physical or psychological problems
26Addiction Characteristics
- First priority is drug acquisition and use
- Negative consequences occur in order
- 1) Interpersonal relationships suffer
- 2) Productivity declines
- 3) Self-Esteem plummets
- 4) Health problems emerge or worsen
- Note Legal problems can occur at any time.
27Why Treatment ?
Rewards
Negative consequences
Utility Theory
- Dysfunctional lifestyle of opioid addiction makes
treatment a desired alternative - Oral methadone and buprenorphine sublingual
tablets are approved for both medical withdrawal
and medical maintenance
28Addictive Behaviors
- Selling prescription drugs
- Prescription forgery
- Stealing drug from others
- Injecting oral formulations
- Buying drugs on the street
- Resistance to change therapy despite evidence of
adverse effects from the drug
29Pseudo-addiction
- Drug-seeking behavior misidentified by health
providers as addictive behavior, when it is
actually relief-seeking behavior - Behaviors resembling those of drug addiction
disappear when patient is given adequate doses of
analgesia
30Pseudoaddiction Behaviors
- Complaints for more drug
- Hoarding drug during pain free periods
- Specific drug requests
- Openly seeking other sources of help
- Occasional unsanctioned dose increases
- Resistance to change in therapy
31Ambiguous Behaviors
- Complaints for more drug
- Hoarding drug during pain free periods
- Specific drug requests
- Openly seeking other sources of help
- Occasional unsanctioned dose increases
- Resistance to change in therapy

48Pain Management and Addiction
Confusion over the distinction between physical
dependence (a state of adaptation that produces
withdrawal signs upon abrupt drug
discontinuation) and addiction (DSM-IV Substance
Dependence) has confounded approaches to the
patient in pain.
49Misconception regarding pain management with
opioids
- Misconception Therapeutic use of opioids is
commonly associated with substance abuse or
addiction - Reality In patients with no history of substance
abuse the risk of addiction following therapeutic
use appears to be less than 3
50Clinical Features Distinguishing Opioid Use in
Patients With Pain Versus Patients Who Are
Addicted to Opioids (TIP 40)
Clinical features Pain Pt. Addicted Pt.
Compulsive drug use Crave drug (when not in pain) Obtain or purchase drugs from nonmedical sources Procure drugs through illegal activities Escalate opioid dose without medical instruction Supplement with other opioid drugs Demand specific opioid agent Cease use when effective alternatives are available Prefer specific routes of administration Can regulate use according to supply Rare Rare Rare Absent Rare Unusual Rare Usually No Usually (break through pain) Common Common Common Common Common Frequent Common Not usually Yes No
51Patient populations under-treated for pain
- Elderly
- Minorities
- Children
- Terminally ill patients with HIV/AIDS
- Chronic non-cancer pain
- Perceived as high addiction risk

52Addict in solid recovery (Group 2)
- May refuse adequate pain pharmacotherapy
- Use of buprenorphine
- Suggest increased support group work while on
analgesic pharmacotherapy - Conduct urine or saliva screens for unauthorized
substances - Utilize pain management contract

53Misconception regarding pain management with
opioids
- Misconception it is illegal to prescribe or
dispense opioids for a patient with a history of
substance abuse - Reality It is not illegal and the regulatory
agencies do not intend to restrict appropriate
therapeutic use
54Management Guideline for Recovering Addicts
- Relapse prevention Relapse occurs most often
when practitioners are unaware of their patients
opioid addiction history (TIP43 p174) - Education regarding the need for drug
- Patients fear and staff reluctance may conspire
to under-medicate - A patients previous drug of abuse should not be
prescribed for pain treatment (TIP 43 p176)

55Undiagnosed substance abuse or addiction active
users (Group 3)
- Screen all patients for substance use disorders
with CAGE - Ask
- Make pain management contingent on thorough
assessment and treatment if warranted - Utilize pain management contract

56Management Guidelines for High Risk (Group 2) and
Active User (Group 3)
- Identify and treat underlying medical problem(s).
- Use appropriate drug, dose, and route
- Employ non-opioids when possible
- Recognize abuse behaviors
- Dont negotiate
- Refer to substance abuse and pain services
- Disclose plan for prescription abuse (Pain
management contract)
57Drug Diverter Not a patientMedico-legal
nightmare
- Do a thorough pain assessment
- Document, document, document
- First time patients who request specific agents
- Abide by pain management ladder dont trade off
good medical practice for convenience
58Policy Barriers to Effective Pain Management
- Lack of training or expertise by healthcare
practitioners and limited access to pain
specialists - Regulatory steps to prevent drug diversion may
also impede pain management (Electronic CDS
prescriptions) - Perceived risk by physicians that sanctions may
be imposed by regulatory boards for over
prescribing opioids for non-malignant conditions
(Chilling Effect) - Poor communication
59Federal Food Drug Cosmetic Act and the Controlled
Substances Act
CSA
FFDCA
Pain specialists may treat a chronic pain
patient currently enrolled in a narcotic
treatment program with narcotics. The CSA does
not set standards of medical practice. It is the
responsibility of individual practitioners to
treat patients according to their professional
judgment for a legitimate medical purpose in
accordance with generally acceptable medical
standards. P. Good (2000) Chief Liaison and
Policy Section, Office of Diversion Control DEA.
60The Pharmacists Dilemma To fill or not to fill
Therapeutically Appropriate
Yes No
Yes OK Dispense Resolve problem (dose, route interaction)
No Resolve document problem Dont dispense
Legally Valid
61Corresponding Responsibility Rule21 CFR 1306.04
- A prescription for a CDS to be effective must be
issued for a legitimate medical purpose by an
individual practitioner acting in the usual
course of his professional practice. The
responsibility for the proper prescribing and
dispensing of CDS is upon the prescribing
practitioner, but a corresponding responsibility
rests with the pharmacist who fills the
prescription. An order purporting to be a
prescription issued not in the usual course of
professional treatment or in legitimate and
authorized research is not a prescription and the
person knowingly filling such a purported
prescription as well as the person issuing it
shall be subject to the penalties provided for
violations of the provisions of law relating to
CDS.
62Federal CDS schedules
I High abuse potential No current accepted medical use May be used in research Heroin, LSD, MDMA
II High abuse potential Accepted medical uses Morphine, hydromorphone, methadone, oxycodone, cocaine, amphetamines
III Less abuse potential than I and II Accepted medical uses Opioid combined with non-opioids, anabolic steroids, buprenorphine
IV Less abuse potential than III Accepted medical uses Benzos, Chloral hydrate, phenobarb, fenfluramine.
V Less abuse potential than IV Accepted medical uses Antitussives with limited amounts of codeine
63CDS Requirements
II Signed prescriptions no refills prescriber must be registered with DEA
III IV Written, oral, or faxed prescription refill 5 times in 6 months prescriber must be registered with DEA
V Written, oral, or faxed prescription refill as authorized prescriber must be registered with DEA
- Emergency prescriptions require follow up

65Red Flags for Prescription Forgery
- The prescription is too legible
- Standard abbreviations are not used
- The prescription appears to be photocopied
- More that one ink color or handwriting used
- Erasure marks visible
- Paper appears to have been wet. (acetone)
- Odd combinations of medications
- Someone other than the patient presents the
prescription for dispensing\
66Prescription Drug Monitoring Programs
- Electronic PDMP passed in 2006 Maryland general
session (SB 333 HB 1287) and was vetoed by Gov.
Ehrlich on May 26, 2006. - As of April 2005, 22 states already adopted
electronic PDMPs - Of the various PDMP approaches (serial Rx,
triplicate) electronic systems are the least
intrusive and chilling on prescribing practices.
Brushwood DB, Hahn KL and Rickert ED (2005)

Opioids 2005 update. American Pharmacists
Association CE Monograph
67Federation of State Medical Boards
- The board will judge the validity of prescribing
on the physicians treatment of the patient and
on available documentation, rather than on the
quantity and chronicity of prescribing - Evaluation of patient, treatment plan, informed
consent and agreement for treatment, periodic
review, consultation,medical records, compliance
with regulations
68Case Acute Pain
- Patient with hx of heroin addiction who is
currently receiving buprenorphine sublingual
tablets (Suboxone) comes to Acute Care Center
with compound fracture of the right femur.
69Case Acute Pain - Issues
- Ability to control pain in patient receiving
chronic partial antagonist therapy - Risk of relapse
- Uncontrolled pain may delay/impair rehabilitation
and recovery
70Case Acute Pain- Strategies
- Non-pharmacologic and non-opioid interventions
should be optimized first - Engage patient in strategies that have aided in
their recovery as soon as possible - Consult addiction medicine specialist
- When opioids are necessary, use long-acting,
slower onset formulations when possible - Must D/C buprenorphine in order to obtain full
agonist effect of mu agonists.
71Examples of Nonpharmacologic Interventions for
Pain
- Cognitive-Behavioral
- education/instruction
- relaxation
- imagery
- music distraction
- biofeedback
- Physical Agents
- heat or cold compress
- massage, exercise, immobilization
- transcutaneous electrical nerve stimulation

73Case Acute Pain- Strategies
- Begin tapering of opioids as soon as possible but
gradually to avoid any withdrawal symptoms - Treat relapse if it occurs
- Re-start buprenorphine therapy
74Misconception regarding pain management with
opioids
- Misconception patients on methadone maintenance
therapy should not be experiencing pain - Reality Reluctance to provide adequate pain
treatment to patients on medication assisted
therapy usually is based on the mistaken belief
that a maintenance dose of opioid addiction
treatment medication also relieves acute pain
(TIP43 p174)
TIP 43 Center for Substance Abuse Treatment.
Medication-Assisted Treatment for Opioid
Addiction in Opioid Treatment Programs DHHS
Publication No. (SMA) 05-4048 Rockville, Md.
75Guidelines for Methadone Patients
- Dont expect the patients methadone maintenance
dose to provide analgesia - Continue patients maintenance dose
- Add analgesic (opioid and otherwise) starting
with usual doses - Anticipate tolerance and the need for higher dose
requirement
76Sample Adult Screening Protocol
- Transition Stresses and ways of coping
- Do you use tobacco? (if so, Are you interested
in quitting?) Do you drink alcohol? - Have you ever experimented with any drugs?
- Ask CAGE or CAGE-AID questions
- Ask Q/F questions on alcohol
- Usually takes less than one minute
77For Especially Sensitive Situations
- Ask about friends first
- Ask about prior use first
- Make normalizing statements before asking
questions
78Review of Pain ClassificationsAcute Pain
- Warning that tissue injury (or disease) has
occurred - Subsides as healing takes place (usually less
than 3 months) - Often accompanied by autonomic responses
tachycardia, tachypnea, hypertension,
diaphoresis, mydriasis - Goal relieve pain and allow healing to occur ?
CURE - evidence supports that pain relief may hasten
healing following many types of injuries
79Review of Pain ClassificationsChronic
Nonmalignant Pain
- May initially be elicited by injury but may
persist long after healing has taken place and
change in characteristics and location - May occur following injury, chronic disease, or
have no definable cause - Examples diabetic neuropathy, radicular or low
back pain - Typically persists for months to years and may be
continuous (persistent) or cyclic (chronic) - Goal relief and management as cycles occur
80Review of Pain ClassificationsChronic
Nonmalignant Pain
- Not associated with autonomic responses
- Frequently associated with depression, anxiety,
fear, sleep disorders, anorexia, disability - Likely to develop physical dependence and
tolerance to analgesics - Use of opioids has been controversial but
becoming more widely accepted in specific
circumstances - Evidence that functionality improves
- Cognitive and motor impairment are not problems
associated with chronic use - Goal relief and rehabilitation (not cure)
81Review of Pain ClassificationsMalignant Pain
- Associated with cancer or some similar
progressive, ultimately fatal disease - Frequently worsens in intensity and spreads to
other areas of the body as the disease progresses - Not associated with autonomic responses
- Frequently associated with depression, anxiety,
fear, sleep disorders, complications of the
cancer and other symptoms including hiccups,
cough, chronic nausea, shortness of breath,
myoclonus, delirium as patient enters final days
to weeks of life - Physical dependence is assumed and patients
usually require higher and higher doses of
opioids due to tolerance and disease progression - Goal relief, maintain function, quality of life,
palliative care
82American Academy of Pain Medicine and American
Pain Society Joint Statement 1997
- Good medical practice for patients receiving
chronic opioid therapy involves - Complete patient evaluation including coexisting
diseases and conditions - Treatment plan inform patient of risks and
benefits of opioids and conditions for
prescribing. - Consultation with specialists
- Periodic review of efficacy, AEs, functional
status, QOL, medication misuse - Thorough documentation
83The VIGIL System
- Verification that the pt. can take the
medication responsibly and that the Rx is genuine - Identification drivers license or other ID
- Generalization establish the general parameters
of the provider-pt relationship - Interpretation the decision to dispense is made
- Legalization ensuring adherence to legal
requirements for treatment
While this process takes time most bona fide
patients will accept or welcome it because it
acknowledges their need for ongoing treatment
with controlled substances and provides rules
for safe conduct with these agents. Bogus
patients will not be willing to meet these
requirements.
84Case Chronic Nonmalignant Pain
- Patient with diabetic neuropathy, degenerative
spinal disease, and history of cocaine (nasal)
dependence. Pain described as shooting up right
leg, dysesthesias, burning and numbness in both
feet. Recurrent diabetic foot ulcers that
required amputation of several toes. Frequently
misses work due to pain. Receiving maximum doses
of gabapentin and SSRI. Previously has failed
trials of imipramine and carbamazepine. A trial
of oxycodone 10 mg Q 4 H improves pain
significantly, however his clinician feels that
he should decide whether he wants to take the
risk of addiction.
85Case Chronic Nonmalignant Pain- Issues
- Past substance abuse places him at greater risk
for opioid abuse and dependence (10-25) - Patient seeking medical attention has a right to
treatments that he may benefit from - Clinicians have ethical responsibility to
intervene and relieve suffering (beneficence) but
should exercise knowledge, skills and experience
in making intervention decisions - Clinicians should not knowingly cause unwanted
injury or suffering - Inadequate treatment of pain has been found to be
criminal negligence and malpractice in courts
86Case Chronic Nonmalignant Pain- Issues
- If patient is impaired, does he have the capacity
to understand risks and make judgment? - Determining etiology and pathophysiology of
chronic pain syndromes if often difficult - Chronic pain is often complicated by depression
and anxiety which may limit patients ability to
make balanced decision and other complications of
unrelieved pain
87Case Chronic Nonmalignant Pain- Issues
- Unrelieved or undertreated pain may
- provoke drug abuse in patients with substance
abuse - prevent patient from fulfilling responsibilities
that impact others salary, benefits
88Case Chronic Nonmalignant Pain-Strategies
- Non-opioid strategies should be evaluated prior
to initiation of opioids including co-analgesics - Individuals caring for patient should be
experienced in chronic pain, substance abuse and
use of opioids in patients with history of
substance abuse
89Case Chronic Nonmalignant Pain-Strategies
- When opioids are considered
- Patient should be informed (in writing) of
potential risks and benefits and conditions of
treatment and given opportunity to accept or
reject opioid trial - Pain Management contract
90Case Chronic Nonmalignant Pain-Strategies
- Special monitoring and clear limits regarding
opioid use should be set (to avoid secondary harm
of substance abuse) - Prescriptions are for fixed amounts, clinicians
should see patients more frequently than other
patients - Single pharmacies
- Pharmacy will not accept opioid prescriptions
from other than contracted prescriber - Inappropriate behavior, accelerated use of
opioids etc will result in screening
91Case Chronic Nonmalignant Pain-Strategies
- Treatment goals should be clearly established
pain relief, function, quality of life - Pain should be adequately treated using
standardized guidelines (including use of
breakthrough medications) may lead to
pseudoaddiction or abuse - Opioid doses in patients with history of
substance abuse frequently are higher than
typical doses - Underdosing may provoke or exacerbate abuse
92Case Chronic Nonmalignant Pain-Strategies
- Due to prior history of abuse, patient should
connect (if not already) with AA or NA, etc or
formal treatment program some clinicians may
require participation for prescriptions
93PharmacotherapyGeneral Principles
- Around-the-clock dosing and long-acting
formulations for continuous pain - As-needed immediate-release analgesic
supplementation for breakthrough pain - Observe for end-of-dose failure
- Incident pain prophylaxis
- Spontaneous pain suggestive of visceral/neuropathi
c etiology - Anticipate, prevent, and treat predictable SEs
- Constipation
94Conclusions
- There is no easy formula for dealing with this
common yet complex area of patient care - Engage addiction specialists sooner rather than
later
95Conclusions
- Consider referral to pain management specialist
when standard approaches fail and discomfort sets
in before the situation has escalated out of
control. - Employ the assistance and cooperation of a
competent pharmacist who maintains a patient
centered pharmacy practice.
