Opioid use dysfunction throughout being pregnant in Tennessee: expediency vs.
science

Summary
Methadone and buprenorphine are extremely efficient and generally prescribed for the
remedy of opioid use dysfunction. Each medicines are additionally efficacious for the remedy of
pregnant girls with this dysfunction. In a single third of states, nonetheless, Medicaid reimbursement
will cowl the price of buprenorphine, however not methadone, to deal with opioid use dysfunction in
pregnant girls. This commentary will discover the scientific and coverage rational and
penalties of this coverage, with the opinion that this strategy is guided by political
expediency slightly than sound scientific analysis. The commentary will give attention to the pharmacological administration of prescription opioid dependence throughout being pregnant in Tennessee, one
of the states that limit Medicaid protection of pregnant girls to buprenorphine. Tennessee
can also be related in that this state ranks second nationally within the charge of prescriptions written for
opioid ache relievers; in distinction to injection opioid use in city populations, opioid habit
in rural and southeastern areas of the US is characterised by use of non-injection prescription
opioids. Till lately, most research-based suggestions for the administration of opioid
use dysfunction throughout being pregnant have derived from research of ladies utilizing opioids
intravenously. The dearth of analysis in non-injection opioid-using pregnant girls might
partially clarify why coverage slightly than scientific proof guides Medicaid reimbursement. It’s
hoped that future analysis in pregnant girls hooked on prescription opioids will make clear
which opioid addicted pregnant girls have higher outcomes with buprenorphine or
methadone remedy and these findings, in flip, will inform Medicaid reimbursement.

A rising public well being concern
Opioid use dysfunction in being pregnant is of mounting public well being
concern in our nation, complicating an estimated 54 000
pregnancies yearly (1). A variety of penalties of
opioid publicity throughout being pregnant for mom, fetus, and the
neonate have been described and questions persist as to
whether or not adversarial results proceed into toddler improvement and
past (2). Neonatal abstinence syndrome (NAS) is a
postnatal withdrawal syndrome, first described in heroinexposed newborns; extra lately, different elements than opioid
publicity have additionally been implicated on this scientific syndrome
(three). NAS presents with an array of scientific indicators, together with
feeding issue, autonomic dysfunction, and behavioral
misery. NAS has turn out to be well known as a serious
healthcare expenditure related to opioid use dysfunction
throughout being pregnant and accordingly has been recognized as an
necessary focus for prevention efforts (four). The incidence of
NAS elevated considerably in america between
2000 and 2009 (three). This improve has been hanging in
Tennessee, the place 29% of pregnant girls enrolled in
Medicaid (TennCare) stuffed opioid prescriptions throughout
- From 1995–2009, pregnancy-related use of opioid
analgesics almost doubled amongst TennCare members (5).
From 2009–2011, the speed of NAS amongst infants in TennCare
elevated from 6.zero–10.7 per 1000 births (6) and to 11.6 in
2013 (four) – representing a 16-fold improve since 2000. This
commentary focuses on opioid agonist remedy as a
significant factor of the administration of prescription
opioid use dysfunction throughout being pregnant in Tennessee, of
specific curiosity, as this state ranked second nationally in
the speed of prescriptions written for opioid ache relievers, at
1.four per particular person in 2012 (7). In rural and southeastern areas
of america, comparable to Tennessee, the place opioid
habit is predominantly characterised by non-injection
use of prescription opioids, out there therapeutic selections for
opioid use dysfunction have turn out to be restricted to buprenorphine
as an alternative of methadone, seemingly a coverage determination, not one
guided by the out there scientific proof which helps the
efficacy of each medicines.

The Tennessee strategy: criminalization to
‘‘encourage’’ remedy however no Medicaid entry
to methadone
Even these very excessive charges of NAS in Tennessee seemingly
underestimate using opioids throughout being pregnant due to
important underreporting attributable to stigma related to drug
use issues. This stigma is significantly exacerbated by latest
Tennessee laws which ‘‘permits prosecution of a lady
for assault for the unlawful use of a narcotic drug whereas
pregnant, if her little one is born hooked on or harmed by the
narcotic drug and the habit or hurt is a results of
her unlawful use of a narcotic drug taken whereas pregnant’’
(http://state.tn.us/sos/acts/108/pub/computer0820.pdf). This laws clearly might deter pregnant girls from searching for prenatal
look after worry of being reported. Nevertheless, the legislation must also
be considered as providing incentive for habit remedy and
restoration because it subsequent states that, ‘‘It’s an affirmative protection to
a prosecution … that the girl actively enrolled in an
habit restoration program earlier than the kid is born, remained
in this system after supply, and efficiently accomplished the
program, no matter whether or not the kid was born hooked on
or harmed by the narcotic drug.’’ Interpretation of this
laws is difficult primarily based on latest findings that opioid
sort, together with methadone and buprenorphine upkeep,
and tobacco and SSRI antidepressant use all considerably
improve danger of NAS (6).
To be able to try to include the prescription opioid
epidemic within the state, the Tennessee Division of Well being has
applied a Managed Substance Monitoring Database
(CSMD) program and necessary training for prescribers
(http://well being.state.tn.us/boards/ControlledSubstance/index.
shtml). This program mandates that pharmacies report all
managed drug prescriptions in a centralized database that
physicians should search in real-time previous to offering a
prescription for a managed drug to any affected person. Nevertheless, the
excessive incidence of NAS has not diminished, a lot in order that
the primary statewide surveillance system for NAS was lately
applied by the Tennessee Division of Well being to permit
research of prevention of this critical complication of prescription opioid dependence (four).
Choices for administration of opioid use dysfunction throughout
being pregnant embrace upkeep on an opioid agonist accredited
for habit remedy or cleansing (1). With cautious
monitoring, the prescribed opioid analgesic can also be
continued or discontinued slowly by tapering. Detoxing
from opioids throughout being pregnant has not been the advisable
course for greater than 40 years, notably not for ladies with
essentially the most extreme type of opioid use dysfunction, particularly those that
use intravenous opioids; such pregnant girls are not possible
to have the ability to keep away from relapse with out pharmacological Help (eight).
Methadone upkeep remedy, as at the moment broadly
employed all through america, stays the usual
of look after agonist remedy of opioid use dysfunction in being pregnant
(1). Though consensus holds methadone upkeep because the
commonplace in opposition to which different remedies of pregnant girls
with opioid use dysfunction should be in contrast, TennCare doesn’t
cowl the price of methadone upkeep. Tennessee just isn’t
alone: roughly a 3rd of states don’t present for
methadone upkeep remedy of pregnant girls (9).
Coverage slightly than evidence-guided scientific apply?
Disparities amongst states in Medicaid Help for remedy of
these pregnant girls just isn’t simply understood by inspecting
the revealed proof alone. Does excluding methadone
from the therapeutic armamentarium for pregnant opioidaddicted girls replicate merely an ill-advised political determination or are these applicable regional insurance policies as a result of
related proof supporting methadone upkeep in
their populations just isn’t available? State legal guidelines and
rules pose important implications for practitioners in
that coverage would possibly affect scientific apply in a way that
just isn’t completely in line with suggestions within the
scientific literature (10).
With out opioid agonist remedy, which reduces drug
craving and use, those that are hooked on intravenous
opioids are acknowledged to be at a very excessive danger of
relapse and consequently opioid overdose, untimely labor
triggered by repeated episodes of withdrawal, publicity to
intravenously transmitted infections, and penalties of
involvement with the prison justice system. Proof-based
remedy consists of administration of a therapeutic day by day dose
of methadone offered throughout the context of a complete
remedy program comprising psychiatric and obstetrical
prenatal care, counseling and group remedy, and social work
companies (11). Methadone upkeep as compared with
lively intravenous opioid habit has been proven to consequence
in improved adherence to prenatal care, elevated fetal
development, and decreased danger of HIV an infection, preeclampsia,
and foster care placement of the neonate. However, NAS
of great severity to require remedy with morphine is
nonetheless noticed in properly over 50% of pregnancies on methadone
upkeep (12). Therefore, if absence of NAS is one criterion
for remedy efficacy, as inferred from the above-mentioned
Tennessee legislation, methadone upkeep, whereas it’s evidencebased apply, might not be the most effective we will do. Additionally, focusing
solely on NAS, because the Tennessee legislation does, misses the
chance that girls who relapse throughout being pregnant might
by no means even attain supply due to problems of
accelerated opioid use dysfunction (13,14).
Altering face of opioid habit
By not masking methadone prices, TennCare, like Medicaid in
the opposite non-methadone states, limits entry to methadone,
nevertheless it does make sure that opioid-dependent Tennesseans can
obtain buprenorphine throughout being pregnant at a restricted day by day
dose, with prior authorization (http://www.tn.gov/tenncare/
varieties/ben11001.pdf). This coverage could also be a mirrored image of the
altering face of opioid habit amongst pregnant girls
attributable to an ever-expanding prescription opioid epidemic (1).
From an issue affecting predominantly disenfranchised
internal metropolis girls utilizing intravenous heroin, a a lot bigger,
demographically numerous inhabitants hooked on prescription
opioid analgesics has turn out to be broadly distributed all through
smaller city and rural areas of america. This
improve in prescription opioid use dysfunction is attribute of
southeastern states, together with Tennessee. Not solely is the
sample of opioid use completely different within the Southeast and in rural
areas, however this sample of opioid habit represents a
significantly bigger problem in absolute numbers than do
368 P. R. Martin & A. J. Reid Finlayson Am J Drug Alcohol Abuse, 2015; 41(5): 367–370
injection opioid customers. For instance, in 1997, annual portions
of opioid ache relievers prescribed had been equal to 96 mg
of morphine per particular person; by 2007, charges had reached the
equal of 700 mg of morphine per particular person. In 2010,
2 004 000 individuals aged 12 or older initiated non-medical
opioid ache reliever use (virtually as excessive as the two 426 000 for
marijuana) in comparison with solely 140 000 for heroin (15). These
tendencies recommend that administration of non-injection prescription
opioid use throughout being pregnant will proceed as a serious scientific
problem and that states like Tennessee could also be legislating
care primarily based upon epidemiologic knowledge. Nevertheless, methadone
remedy in being pregnant requirements had been established in giant
city areas from which a lot of the NIH-funded analysis
guiding practitioners, up to now, has been performed.
Administration of non-injection vs. injection
opioid habit
Though non-injection opioid habit has fewer extreme
medical problems than injection drug use (16), overdose
deaths attributable to opioid analgesics lately surpassed heroin and
cocaine, rivaling demise charges from motorcar accidents in
absolute phrases as reported by the CDC (17). So, whereas
ingested prescription opioids have been thought-about a ‘‘safer’’
dosage kind in comparison with intravenously administered opioids,
penalties of those medicine are removed from benign and can’t
be ignored. In actual fact, an more and more frequent scientific trajectory
is to change to intravenous or smoked heroin from prescription
opioids (13,14) primarily based upon altering provide and demand,
unintended penalties of tighter regulation of prescribing.
Even though we don’t actually know which sufferers
(injection or non-injection) do higher on methadone or on
buprenorphine, TennCare and the Medicaid formularies of
many demographically comparable states present buprenorphine
slightly than methadone for opioid use dysfunction remedy.
Whereas it could be ultimate to find out for every particular person
whether or not a partial (buprenorphine) or full (methadone) mu
opioid agonist mixed with structured psychosocial care of
the mom throughout gestation can lead to a more healthy neonate at
the purpose when opioid publicity stops at supply (1), the opposite
excessive, a public well being strategy, makes an attempt to achieve
the best variety of sufferers with an evidence-based
strategy (18).
The chance-benefit Assessment supporting methadone upkeep for intravenous opioid addicted pregnant girls may be very
compelling (eight,19,20), however comparable research in non-injection
opioid use dysfunction sufferers, who get hold of these medicine from the
road or by prescription from their docs for ache management,
are solely now rising from different rural states like Vermont.
The findings recommend that buprenorphine is the same as, or might
be even higher, for prescription opioid addicted pregnant
girls (21). The scenario is considerably extra sophisticated by
the truth that the route of heroin administration has change
dramatically prior to now 10 years as a result of purity of the drug
that enables for smoking or snorting (22). It might be argued that
a few of these girls hooked on prescription opioids might
properly be detoxified or tapered off the opioid, thus avoiding
NAS for his or her little one. Nevertheless, the chance of continued
abstinence with out upkeep remedy just isn’t very excessive in
oral prescription opioid use dysfunction both (23); therefore, the
dangers of repeated cycles of intoxication and withdrawal, albeit
much less extreme, do exist with prescription opioids as properly. A case
can thus be made for upkeep with an opioid agonist to
scale back craving and dangerous use, however these girls might not
require the intensive (costly and time-consuming) day by day
monitoring mandated by legislation for methadone upkeep.
Buprenorphine upkeep: the sensible alternative
for pregnant prescription opioid addicts
Buprenorphine seems to be a very applicable alternative
for administration of the pregnant prescription opioid addict
as a result of it has been accredited for office-based upkeep of
opioid habit, thus eliminating boundaries related to
day by day visits to a methadone clinic. Buprenorphine can be utilized
throughout being pregnant with little danger to the fetus, and being pregnant
outcomes aren’t considerably completely different from these obtained
with methadone (24). Buprenorphine, a partial mu opioid
agonist and kappa opioid antagonist, causes much less activation of,
and has larger affinity for the mu-opioid receptor than
methadone. Moreover, there may be much less placental switch of
buprenorphine than methadone. These concerns, in
concept, ought to result in decreased bodily dependence of the
fetus with buprenorphine and fewer extreme related NAS
upon supply. The MOTHER research, a randomized managed
trial evaluating buprenorphine and methadone publicity
throughout being pregnant, offered some Help for these predictions (12). Infants uncovered to buprenorphine throughout gestation
had been discovered to spend fewer days within the hospital and required
decrease morphine doses over a shorter remedy interval for
NAS than these uncovered to methadone, whereas each opioid
agonists had been equally properly tolerated and efficient in
lowering illicit drug use.
Additional analysis is required to find out the suitable
scientific threshold for opioid prescribing in being pregnant,
together with opioid agonist upkeep in girls who’re
hooked on prescription opioids and use them solely by way of noninjection routes. That is probably a special inhabitants than
that from which a lot of the current analysis guiding
remedy is at the moment out there.
