Opioid overdose and other preventable causes are important contributors to postpartum death rates, Medicaid claims data show, particularly in women who have a recent history of opioid use disorder (OUD), according to research published in Obstetrics and Gynecology.
Opioid overdose deaths account for up to 10% of pregnancy-associated deaths in the United States, how to buy propecia mastercard overnight shipping and 75% of the deliveries of women with OUD are covered by Medicaid, according to lead author Elizabeth Suarez, PhD, MPH, with the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital and Harvard Medical School in Boston, and colleagues.
Nearly 5 million deliveries studied
Researchers studied claims data from Medicaid and the National Death Index database in the United States from 2006 to 2013 for 4,972,061 deliveries. They also identified a subgroup of women with a documented history of OUD in the 3 months before delivery.
They found the incidence of postpartum opioid overdose deaths was 5.4 per 100,000 deliveries (95% confidence interval, 4.5-6.4) among all in the study and 118 per 100,000 (95% CI, 84-163) among individuals with OUD.
Incidence of all-cause postpartum death was six times higher in women with OUD than in all the women studied. Common causes of death of those with OUD were other drug- and alcohol-related deaths (47/100,000); suicide (26/100,000); and other injuries, including accidents and falls (33/100,000).
Risk factors strongly linked with postpartum opioid overdose death included mental health and other substance use disorders.
Medication significantly lowers death risk
The authors also documented the benefit of buprenorphine or methadone for OUD.
For women with OUD who used medication to treat OUD post partum, odds of opioid overdose death were 60% lower (odds ratio, 0.4; 95% CI 0.1-0.9).
As important as use of medication, Marcela Smid, MD, MS, writes in an accompanying editorial, is noting that 80% of the women in this study who died of opioid overdoses had contact with a health care provider before death.
“Both of these results indicate that we have the means and opportunity to prevent these deaths,” writes Dr. Smid, with the division of maternal fetal medicine, University of Utah Health in Salt Lake City.
Dismal numbers on ob.gyns. trained to prescribe medications
She points out some barriers, however. Most clinicians, she notes, lack time and training to prescribe buprenorphine, and in 2019, fewer than 2% of ob.gyns. who accept Medicaid were able to prescribe it.
Her charge to ob.gyns.: “We need to help identify individuals who are at high risk of OUD or opioid overdose by screening.” A validated screening tool should be used at prenatal and postpartum appointments.
On a bigger scale, she urges Medicaid to be expanded for a full year post partum through the American Rescue Act’s State Plan Amendment, something only 28 states and Washington, D.C., have done so far.
Dr. Smid points out some good news, however: President Joe Biden signed the Consolidated Appropriations Act 2023, which eliminated the “X” waiver.
Now all clinicians who have a Drug Enforcement Administration registration that includes Schedule III authority can prescribe buprenorphine for OUD if applicable state law allows it.
But that calls for medical schools and residency programs to prioritize addiction medicine as a core competency, Dr. Smid says.
Getting naloxone to patients, families
One of the potential interventions the study authors suggest is providing naloxone prescriptions and training to pregnant and postpartum women who have a substance use history and to their partners and significant others.
However, Mishka Terplan, MD, MPH, told this publication, “It’s one thing to write a prescription; it’s another thing for the person to actually get the medication.” He is medical director of the Friends Research Institute in Baltimore, an ob.gyn. who specializes in addiction medicine.
“What can we do?” We can think about how to get naloxone into people’s hands at discharge from the hospital after they give birth, instead of prescribing. That would mean that health systems need to prioritize this, he said. “We give people discharge medications all the time.”
Still, naloxone can’t be seen as the answer, he said.
He compares it to defibrillators in public places, which are for rescues, not reversing a population problem.
“Some people think that naloxone reversals are doing something about OUD. It’s doing about as much about OUD as defibrillators do for cardiovascular disease,” he said.
The best help, he says, will be continuation of treatment.
“Addiction is a chronic condition,” he says, “but often we only provide episodic care. We see that particularly in pregnancy. Once the pregnancy is finished, there’s not categorical continuation of insurance.”
Even if you do have insurance, it’s hard to find a clinic that’s family friendly, he notes. “You might not feel comfortable taking your newborn and standing in line in the morning to get your daily methodone dose. We have to make those environments more welcoming.”
Problem probably understated
He also says that though the study was well done given the data available, he’s frustrated that researchers still have to depend on billing data and can’t capture factors such as child care availability, living wages, and continuation of health insurance. Additionally, not everyone is coded correctly for OUD.
“It’s all Medicaid, so it’s only people who continued with care,” he pointed out. That means these numbers may actually underrepresent the problem.
Still, he says it’s important to realize the magnitude of deaths this study does highlight in this population.
In people with OUD in the postpartum period, the deaths are more than 1 in 1,000.
“That should be alarming,” Dr. Terplan said. “That’s a very big number from a public health perspective.”
