Misconception #1Addiction is a character flaw or moral failing
“It’s time to change how we view addiction…Not as a moral failing but as a chronic illness that must be treated with skill, urgency, and compassion. The way we address this crisis is a test for America.”
Vivek Murthy, MDUS Surgeon General
McCarthy M. US must address addiction as an illness, not as a moral failing, Surgeon General says. BMJ. 2016 Nov 22;355:i6265.

Opioids and neurocognitive development and birth defects
Neurodevelopmental effects
Animal models note changes in dendritic length, synaptic plasticity, neuronal proliferation, cholinergic function, increase in apoptosis in dopaminergic cell structures in the hippocampus
• Human studies
– Delay in cognitive function
– Lower verbal, reading, arithmetic ability
– Increased ADHD
– Decreased brain volumeBeckwith AM, Burke SA. Identification of early developmental deficits in infants with prenatal heroin, methadone, and other opioid exposure.

Opioids and neurocognitive development and birth defects
Neurodevelopmental effects
• Israel Study, N=160 5-12 year olds– Children exposed to heroin in utero
– Controls:
• 2 groups of normally developing children
• Children with fathers using heroin
• Children born to families with socioeconomic depravation
– Highest rates of inattention in socioeconomic depravation group
– Highest rates of inattention, hyperactivity, aggression children born to opioid using parents raised by biologic parents
– Adopted children preformed normally

Opioids and neurocognitive development and birth defects
Neurodevelopmental effects
• Nygaard et al, 2015
– N=72 children with opioid and polysubstance exposure
– Assessed at 1, 2, 3, 4.5, 8.5 years
– Controlled for socioeconomic status
• Based on parental education
– Exposed group lower cognitive scores
– Boys scored significantly lower than girls
– Did not see cognition catch up over time

Opioids and neurocognitive development and birth defects
Neurodevelopmental effects
“Children of mothers with heroin dependency, if born without significant neurologic damage seem to have normal intellectual potential, as their IQ can be normal if the children are raised in an enviroment without low SES of neglect.” Orney et al, 2001
“Findings indicate continuous negative processes in children born to mothers with opioid and polysubstanceabuse.” Nygaard et al, 2015
Opioids and neurocognitive development and birth defects
Birth defects
• US Collaboration Perinatal Project 1959 – 1965
– Prospective trial

Opioids and neurocognitive development and birth defects
Birth defects• National Birth Defect Prevention Study 1997 – 2005
• 17,499 mothers with cases of birth defects• 2.6% used opioid analgesic use 4-12 weeks • Increased risk of:
– All CHD OR 1.4 (95% CI 1.1-1.7)– Spina bifida OR 2.0 (95% CI 1.3-3.2)– Hydrocephaly OR 2.0 (95% CI 1.0-3.7)

Opioids and neurocognitive development and birth defects
Neurodevelopmental effects and birth defects
• Carefully consider control groups in these studies
• Environment plays a major role in development
• Women with substance use disorder have increased incidence of other risk factors
• Risk for birth defects remains unclear
Misconception #4“Opioids cause maternal
pregnancy complications”
Pregnancy complications
• Pre-eclampsia
• Premature labor
• Premature preterm rupture of membranes
• Placental insufficiency
• Placental abruption
• Intrauterine growth restriction
• Intrauterine fetal demise
• Low birth weight
• Small head circumference
• Neonatal withdrawal syndrome

Misconception #5“All I need to do is detox from everything”
Opioid detoxification during pregnancy
Stewart et al, 2013
– N=95 pregnant women detoxed with methadone• 53% patients successfully completed detox
• 32% left the study
Jones et al, 2017– Reviewed 500 documented cases of opioid detox– Opioid detoxification associated with:
• Less time in treatment, fewer prenatal care visits, less likely to deliver at study hospital
– No fetal losses attributed to medically assisted withdrawal
– Relapse 17-96% (average 48%)Stewart RD, Nelson DB, Adhikari EH, McIntire DD, Roberts SW, Dashe JS, Sheffield JS. The obstetrical and neonatal impact of maternal opioid detoxification in pregnancy.

Misconception #5“All I need to do is detox from everything”
Opioid detoxification during pregnancy
• Detoxification not recommended due to:– Decreased neonatal birth weight
– Decreased prenatal care
– Illicit drug relapse
– Resumption of high risk behaviors (IVDU, prostitution, criminal activity)
Medication assisted treatment (MAT)
• Reported success rates 63-82%

Substance use disorder v Physical dependence
• Opioid use disorder (DSM V)
– Problematic pattern of use leading to clinically significant impairment or distress (in past 12 mo)
1. Taken in larger amounts or longer duration
2. Desire to cut back or unsuccessful efforts to cut back
3. Great deal of time obtaining, using, or recovering
4. Craving, strong desire, urge
5. Recurrent use resulting in failure to fulfill obligations
6. Continued use despite persistent or recurrent social or intrapersonal problems
Substance use disorder v Physical dependence
• Opioid use disorder (DSM V)
– Problematic pattern of use leading to clinically significant impairment or distress (in past 12 mo)
7. Give up important social, occupational, recreational activities
8. Recurrent use in physically hazardous situations
9. Continued use despite knowing physical or psychological problems
10. Tolerance*
11. Withdrawal*
Substance use disorder v Physical dependence
• Physical dependence
– Tolerance: loss of effect after repeated use, leading to need for higher doses to achieve desired effect
– Withdrawal: constellation of unpleasant symptoms that occur after abstinence to a substance
Medication Assisted Treatment
Methadone
• Full opioid agonist
• T1/2= 36-48 hours
• Dosed at certified opioid treatment program
Buprenorphine
• Partial opioid agonist
• T1/2: 36 hours
• Physicians & PA and ARNP*
• Combination naloxone to prevent diversion
Misconception #8“Buprenorphine is better than methadone”
MethadonePros:• Daily observed dose• Less risk for diversion• Full opioid agonist
– No precipitated withdrawal
• Ancillary services at methadone clinic
• Better retentionCons:• Daily observed dose• QTc prolongation• Medication interaction• Prolonged induction• More stigma• Less available in rural area
BuprenorphinePros:• Office based treatment • Less stigma• Less overdose risk• Induction fasterCons:• Withdrawal to start• Partial opioid agonist
– Risk of precipitated withdrawal
• Higher diversion risk• Ceiling effect for high
equivalence doses• Fewer prescribers
Misconception #9“I don’t want my baby born addicted”
“I don’t want my baby to go through withdrawal”

Neonatal Abstinence Syndrome
• Pearls:• Explain ORT as a healthy treatment in pregnancy and
treatment as NAS as part of it• Prepare and set expectations • Compare to glucose in neonates of GDM• Encourage mother to be mother• NAS improved with rooming in and skin to skin• NAS improved with breastfeeding
Misconception #10“I want to keep my dose low to
decrease baby’s withdrawal”
Dose of methadone not associated with severity of neonatal withdrawal
• Meta-analysis of 29 studies• Less NAS with 20-40 mg• No difference in risk when
comparing the prospective studies or in studies with objective scoring tools
Cleary BJ, Donnelly J, Strawbridge J, Gallagher PJ, Fahey T, Clarke M, Murphy DJ. Methadone dose and neonatal abstinence syndrome-systematic review and meta-analysis. Addiction. 2010 Dec;105(12):2071-84.
Misconception #11“I’ll have to be on methadone the rest of my life”
“I’ll taper off after I deliver”
Wilder C, Lewis D, Winhusen T. Medication assisted treatment discontinuation in pregnant and postpartum women with opioid use disorder. Drug Alcohol Depend. 2015 Apr 1;149:225-31.
Discontinuation rates:• Prenatal: 0-33%• Postpartum: 26-64%• 50% will be off
methadone by 6 months
Encourage treatment as long as it is working• At least 1 year
Misconception #14“ORT is adequate for acute pain”
“You can’t have adequate pain relief on ORT”
“Prescribing opioids for pain will cause relapse”
Acute pain management while on buprenorphine or methadone
• Home dose not enough for acute severe pain • Possible to have adequate pain control after delivery
– Consider high affinity opioid mu receptor agonists• 2-4 times the normal dose • Hydromorphone PCA• Hydromorphone (Dilaudid) approx 3-6 mg q3h
– Morphine (Duromorph) spinal (18hrs)– Utilize non-opioid medications like APAP & NSAIDs– Mildfulness, stress reduction
• No studies show that prescribing opioids for acute pain will cause relapse
Alford DP, Compton P, Samet JH. Acute pain management for patients receiving maintenance methadone or buprenorphine therapy. Ann Intern Med. 2006 Jan 17;144(2):127-34. Review. Erratum in: Ann Intern Med. 2006 Mar 21;144(6):460. Meyer M, Wagner K, Benvenuto A, Plante D, Howard D. Intrapartum and postpartum analgesia for women maintained on methadone during pregnancy. Obstet Gynecol. 2007 Aug;110(2 Pt 1):261-6.
Conclusions
• Opioid exposure in utero may be linked with neurocognitive deficits in children which may be overcome by environmental stability
Conclusions
• Lack of adequate control in studies and complicated confounders makes it difficult to ascertain if in utero exposure of opioids causes birth defects
Conclusions
• Medication assisted treatment with methadone or buprenorphine is the standard of care for opioid use during pregnancy
