4 Target Audience The overarching goal of PCSS-O is to offer evidence-based trainings on the safe and effective prescribing of opioid medications in the treatment of pain and/or opioid addiction. Our focus is to reach providers and/or providers-in-training from diverse healthcare professions including physicians, nurses, dentists, physician assistants, pharmacists, and program administrators. 4

5 Educational Objectives At the conclusion of this activity participants should be able to: Describe current guidelines and evidence about using treatment agreements and urine drug testing for patients with chronic pain. Demonstrate effective communication skills with patients about expectations about prescribing opioid therapy. Illustrate appropriate ordering of urine drug tests and interpreting the results. 5

10 Clinical Question 1 If you decide to prescribe opioids to a patient with chronic pain, how likely are you to use a written treatment agreement? A. Not at all likely B. It depends on the patient s risk for misuse C. Somewhat likely, regardless of risk D. Very likely, regardless of risk 10

11 Evolving guidelines about using written treatment agreements Federation of State Medical Boards (2004) should consider for patients at high risk APS/AAPM (2009) may consider for any patients Washington State (2010) should use for everyone Federation of State Medical Boards (2013) Use is recommended All agree that: 1) providers and patients should discuss goals, risks, and expectations 2) The evidence for using or signing documents is weak 11

12 Patients with misuse behaviors (%) Do treatment agreements work? Before After Aberrant medication taking behavior(1) Multiple sources(2) Multiple sources(3) Illicit drug use(4) Starrels JL, Ann Int Med 2010 (review). 1 Weidemer NL, Pain Med 2007; 2 Goldberg JC.

13 What is a treatment agreement? This contract has 4 parts. Pain Medicine Contract Part 1 Part 2 Part 3 Part 4 Tells you how and when to take your pain medicine. Lists things you agree to do. Lists things that could happen if you do NOT do the things listed in Part 2. Sign the form. You and Dr. must sign the form. PART 1 MY PAIN MEDICINE Medicine Breakfast Lunch Dinner Bedtime American Academy of Family Physicians (AAFP) rt1.pdf The Utah Department of Health (Utah Department of Health.

14 What is a treatment agreement? A document that describes 4 things: 1. Risks & benefits of opioid therapy 2. Treatment plan (multi-modal) 3. Monitoring plan 4. Conditions for discontinuing opioids 14

15 How to use an agreement Focus is safety Communication tool get on the same page Educate, engage, learn about your patient Set goals and expectations For everyone 15

16 Many ways to do this Written documents vary Contract Informed Consent Agreement Treatment Plan Dear Patient letter I prefer these Have the conversation (& document it) 16

17 How not to use an agreement Not a formality ( sign here to get your medicine ) Not to protect you from liability Not a magic bullet False sense of security Not to punish a patient I had to put him on a pain contract 17

18 Agreement should be goal-directed Goals of treatment We do not expect your chronic pain to go away completely. Our hope is that treatment will make your pain more tolerable so that you can do the things you want to do. Goals for me are: 18

19 Agreement should outline the treatment plan I understand: These medicines are only one part of my treatment. I am willing to try other things that my provider suggests. Some examples are physical therapy, counseling, other kinds of medicine, classes to help me manage my pain, or an appointment with a specialist. It is important to attend all appointments with health care providers. 19

20 Agreement should describe patient responsibilities for safe use I will talk to my provider if I feel I need more medicine than was prescribed. I will not change my dose of medicine on my own or take medicine from other people. I will be honest and open with my provider about medicine, alcohol, and street drugs I take. This is important so my provider knows how safe the medicine is for me. I will never give or sell any of my medicine to anyone else. This is dangerous and against the law. I will allow my provider to check my urine to see what medicines or drugs I take. 20

21 Agreement should be two-sided My health care provider will: Work with me to find the best treatment for me. Be honest and open with me about my medicines and treatment options. Ask me about side effects, and treat these side effects or change the medicine. 21

22 Conditions for discontinuing opioids should include benefit-to-risk balance My health care provider might stop or change my medicine if: I do not follow this agreement I use medicines, drugs, or alcohol in a way that my provider thinks is not safe My provider thinks that the medicines are not helping enough My medical conditions change 22

23 When Discontinuing Opioids Frame your concerns in terms of risks and benefits At this point, I am concerned about your safety, and I can t responsibly continue to prescribe opioids Not, you violated the contract If concerned about addiction, discuss and refer or offer treatment In most cases, opioids should be tapered Offer other pain treatments Do not fire or abandon patients 23

25 Evolving UDT Guidelines Federation of State Medical Boards (2004) should consider for high risk patients APS/AAPM (2009) should order for high risk patients and should consider for low-risk patients Washington State (2010) should order for everyone At baseline and randomly All agree that evidence that UDT will impact addiction or overdose is weak 25

26 Patients with misuse behaviors (%) Limited UDT Outcome Studies Aberrant medication taking behavior(1) Multiple sources(2) Before After Illicit drug use(3) Starrels JL, Ann Int Med 2010 (review). 1 Weidemer NL, Pain Med 2007; 2 Manchikanti L, Pain Phys 2006; 3 Manchikanti L, Pain Phys

27 UDT Helps to Identify Risk Identifies undisclosed drug use 11% to 32% POS for unreported drugs 1 Confirms adherence to prescribed opioids 7.5% NEG for prescribed opioid 2 21% to 44% with no other problematic behavior had inconsistent urine test 3 1 Fishbain 1999, Katz 2003, Manchikanti 2003, Shuckman 2008; 2 Fishbain 1999; 3 Katz, Fanciullo. Clin J Pain, 2002; Michna et al. Clin J Pain, 2007; Fleming,

28 Clinical Question 2 Rate your agreement: I feel confident in my ability to interpret urine drug test results for patients prescribed opioids. A. Strongly disagree B. Disagree C. Neutral D. Agree E. Strongly agree 28

29 Internal medicine residents confidence in UDT interpretation Not confident 44% Confident 56% Starrels JL et al. JGIM

30 Confidence in UDT interpretation does not reflect knowledge Knowledge Not confident 44% Confident 56% Passed 27% Failed 73% Starrels JL et al. JGIM

31 Clinical Question 3 RT is Rx d morphine SR BID, & oxycodone/apap BID PRN. RT s UDS returns (+) for opiates, & (-) for oxycodone. Interpret. A. Shouldn t be (+) for opiates. She s probably using heroin. B. Shouldn t be (-) for oxycodone. She is probably selling it. C. This may be consistent with use as prescribed. D. I don t know. 31

32 Two Types of Urine Drug Tests 1. Screening Immunoassay ( urine drug screen ) Detects drug class Opiate screen reliably detects morphine and codeine Less sensitive for semi-synthetic opioids (e.g., oxycodone) Does NOT detect synthetic opioids (e.g., fentanyl) Above a threshold concentration 2. Confirmatory GC/MS or LC/TMS Detects sub-threshold level Detects drugs not reliably detected on screen Confirm presence or absence of a specific drug 32

33 Screening test pitfall: Common causes of false negatives Concentration is below the threshold Incomplete cross-reactivity of the substance you want to detect (e.g., low sensitivity of opiate screen for semi-synthetic or synthetic opioids) Order confirmatory test (e.g., GC/MS) 33

34 Screening test pitfall: Common causes of false positives Amphetamine assay: Many medications, including decongestants, beta-blockers, ranitidine, antidepressants Opiate assay: benadryl, DM, quinolones Marijuana assay: PPIs Cocaine assay: coca leaves, cocaine in dental procedure Order confirmatory test (e.g., GC/MS) 34

35 Two Types of Urine Drug Tests 1. Screening Immunoassay ( urine drug screen ) Detects drug class Opiate screen reliably detects morphine and codeine only Does NOT detect synthetic opioids (e.g., fentanyl, meperidine) Above a threshold concentration 2. Confirmatory GC/MS or LC/TMS Detects drugs not reliably detected on screen May detect a sub-threshold concentration Confirms presence or absence, and concentration, of a specific drug 35

36 Case RT s screen was positive for opiates, which is expected for a patient on morphine. RT s screen was negative for oxycodone, but screen is not sensitive for low doses. You add on a GC/MS for opioids. 36

37 Clinical Question 4 The GC/MS is (+) for Rx d morphine & oxycodone, and for hydromorphone. She denies taking any other pain meds. Interpret. A. It is probably an error B. She probably took unprescribed hydromorphone C. Appropriate; morphine metabolizes to hydromorphone D. Appropriate; oxycodone metabolizes to hydromorphone 37

38 Opioid metabolic pathways Heroin Codeine Hydrocodone Oxycodone 6-MAM Morphine Hydromorphone Oxymorphone 38

39 Clinical Question 5 In a patient prescribed acetaminophen with codeine, one would reasonably expect the following to be detected in the urine: A. Codeine B. Oxycodone C. Morphine D. All of the above E. a and c only 39

40 Clinical Question 6 A pt on chronic oxymorphone therapy tests (-) for opioids on a UDS. He claims to be using the medication as Rx d. Next step? A. Subject this urine to a different kind of test B. Re-administer a urine drug screen at the next visit C. Taper and discontinue opioid therapy D. Refer the pt to a detoxification/rehabilitation center E. Notify law enforcement 40

41 Responding to Unexpected Results There is a differential diagnosis Discuss with patient to gather data Open-ended questions Your urine test didn t turn out like I expected. What can you tell me about that? Not a confrontation May need additional data Confirmatory tests, PMP data, pill counts, toxicologist Consider the results in context of risks and benefits 41

42 Take Home Points Use agreements as a communication tool Use urine drug testing and interpret results with caution Continuously reassess the risks and benefits of opioid therapy Deciding to taper opioids is not the end, can be an opportunity to help patients 42
