I just got back from the AATOD (American Association for the Treatment of Opioid Dependence) conference, and I feel inspired, enthusiastic, and relaxed.
Several days before I left for the conference, I talked to a pregnant patient at one of the opioid treatment programs where I work. This patient, dosing on methadone, said her obstetrician insisted she taper down on her dose during pregnancy. When she told me that, my shoulders slumped with fatigue and disappointment. This was a doctor I’ve called on the phone a few times, and met in person once. We’ve talked collegially, and I physically, personally handed her a copy of ACOG/ASAM (American College of Obstetrics and Gynecology, American Society of Addiction Medicine) position paper on the treatment of opioid-addicted pregnant patients.
Needless to say, that document does NOT advise taper of methadone during pregnancy. When I talked to this obstetrician, I’d explained why we usually need to increase the dose during pregnancy. Yet now she’s telling a patient to lower her dose. This is not best practices.
I felt tired, and hopeless about improving physician education in my area. Do these doctors have Teflon brains, and all the information I’ve been trying to provide keeps sliding off their cortexes, into the ozone somewhere?
Yesterday at the AATOD conference, I heard a lecture by one of the main authors of the MOTHER (Maternal Opioid Treatment: Human Experimental Research) trial, Dr. Karol Kaltenbach. I’ve posted blogs about this trial (see Dec 16, 2010, March 23, 2013), which randomized opioid-addicted pregnant women to treatment with either methadone or buprenorphine. The goal was to compare outcomes of the babies born to moms maintained on methadone versus buprenorphine.
Dr. Kaltenbach opened her lecture by making an excellent point: use of legal drugs such as alcohol and tobacco during pregnancy are viewed as public health problems, even though they cause as much or more harm to the fetus as illicit drugs. Yet the general public demonizes moms who use illegal drugs. Pregnant women who use illegal drugs are faced with harsh moral judgments, and punitive responses.
Alcohol, a legal drug, causes harm to 40,000 kids per year, and is the leading preventable cause of developmental disabilities. Consistently, research shows physical and behavioral effects in the children born to moms who drink alcohol. Even though researchers have stated that there’s no safe amount of alcohol during pregnancy, according to the 2011 NSDUH (National Survey of Drug Use and Health), 9% of pregnant women said they were current drinkers, 2.6 said they were binge drinking, and .4% were heavy drinkers.
Pregnant smokers of tobacco are more likely than non-smokers to have a variety of complications, including spontaneous abortions, placenta previa and placental abruption, retardation of fetal growth, low birth weight babies, and preterm labor and birth. After delivery, the risk of SIDS (Sudden Infant Death Syndrome) is six times higher than for babies of non-smoking moms. Their babies are more likely to have ADHD, inattention disorders, ear and respiratory infections.
Yet newspapers now publish sensational articles about “addicted babies” born to mothers with opioid addiction, while ignoring the more common and more harmful effects of alcohol and tobacco. Remember the “crack baby” scare of the 1990’s, which was a media creation with no backing by science?
From the MOTHER study we learned that babies born to moms on buprenorphine have about the same risk of withdrawal, called neonatal abstinence syndrome (NAS), as babies born to moms on methadone. In both groups, fifty percent of the babies had NAS severe enough to need medication to treat opioid withdrawal. The babies were scored on the Finnegan scale, which grades the babies on many signs of withdrawal to indicate when treatment is needed. (By the way, at the AATOD conference I sat near Loretta Finnegan, creator of the Finnegan scale and internationally recognized for her many contributions to the field of alcohol and drug abuse!)
So in both groups, about half of the babies needed medication for withdrawal symptoms. However, the babies with NAS born to the moms on buprenorphine required 89% less medication (morphine solution) and spent 43% less time in the hospital as compared to the babies with NAS born to moms maintained on methadone. The babies born to moms on buprenorphine also spent 58% less time being medicated to treat their NAS.
That’s a significant benefit.
This study was very important for many reasons, but after these results, buprenorphine is slowly becoming the standard of care for pregnant opioid-addicted moms, if it’s available. True, there was a higher drop out of the moms on buprenorphine, but it was not statistically significant, and the moms didn’t leave treatment; they dropped out of the study for whatever reason.
Now for the exciting part: a supplemental study of these children is being completed. This data hasn’t yet been published, but Dr. Kaltenbach says it will show that kids of moms on methadone and buprenorphine were compared and assessed at three months, six months, twelve, twenty-four, and thirty-six months. A standardized scoring system for infant development called the Bayley Scale was used to study these children, and the groups were compared to scores for normal children.
Dr. Kaltenbach says there are no differences between the babies born to methadone versus buprenorphine, and better yet – both groups showed scores in the normal ranges on this scale. The scale measured things like language and motor skills, cognitive abilities, and conceptual and social skills.
The kids are alright!
This data is going to be a huge comfort to worried moms, dosing on methadone or buprenorphine.
And I got inspired at the AATOD conference. I heard one speaker tell the audience “you do it until they get it. You tell them over and over and over again. Whatever it takes.” And I thought to myself, this is correct. I can’t give up on the obstetricians in my area. Maybe they don’t agree with me, but I am not out on a limb with what I’m saying. It’s backed up with fifty years of studies and science. I am listening and reading information from the experts in the field. I need to be persistent, and keep repeating the data, mailing the data…skywriting the data…whatever.
It’s refreshing to be around people who understand opioid addiction and its treatment. It’s encouraging to hear how workers in the opioid addiction field are finding new ways to help our patients and advocate for them.
I’m going to call this OB – again –and re-inform her – nicely – about what’s found in that position paper, co-authored by doctors from her own specialty. I’m also going to suggest she direct some of her concern towards her patients who use the legal drugs of alcohol and tobacco, since they cause significant harm to infants.
And yes, I know most of the patients enrolled in OTPs also smoke, and I am going to help them with that, too…if they want it.
