Report Shows Spike In San Diego County Babies Born With Drugs In Their Systems

Ever so quietly, a California health agency recently uploaded an alarming chart on its website.

The graphic shows an especially steep rise in the number of newborns affected by drugs transmitted from their mothers during pregnancy or through breast milk starting in 2008, when the number statewide was 1,862. By 2014, the number rose to 3,007.

But the biggest yearly jump came in 2015, when the number of affected babies hit 3,633, a 21 percent climb. That’s despite a steady decline in the number of births in California since 2008.

In San Diego County, that 2014-15 trajectory has been even more dramatic, according to county birth data prepared at inewsource’s request by the Office of Statewide Health Planning and Development, or OSHPD, the agency that collects patient discharge data from hospitals.

The county had 182 cases in 2014 but 289 in 2015 — a 59 percent jump. That didn’t include babies affected who were not born in hospitals. That’s a rate of 6.57 per 1,000 births in San Diego County, compared with 4.08 in 2014 and 1.82 in 2008. In 2015, the statewide average was 7.29, up from 5.9 in 2014.

State and county health officials couldn’t say what is behind the spike other than more pregnant women are using addictive drugs. But other possible explanations include clinical policy changes that promote more aggressive infant and mother screening, expanded definitions of populations at high risk, and a new national diagnostic coding system that took effect Oct. 1, 2015.

Newborns affected by drugs

In 2015, 7.29* out of every 1,000 babies born to California parents was affected by drugs transmitted by placenta or breast milk. That ratio has increased since 2008. *This rate does not include babies affected who were not born in a hospital.

A topic for aggressive detection

Neonatal experts say babies are screened for drugs when the mother or family member acknowledged that she used — or is known to have used — narcotics, cocaine, hallucinogens or another addictive drug during pregnancy, or when babies exhibit signs of withdrawal within the first 48 hours after birth. In the medical world, these symptoms are called neonatal abstinence syndrome or NAS.

“The baby might be sneezing, jittery, or irritable and not be able to be consoled, or they might have diarrhea or a lot of other relatively subtle signs that nurses are trained to look for,” said Dr. Lawrence (Lance) Prince, chief of UCSD’s and Rady Children’s Hospital’s division of neonatology. His division runs neonatal intensive care units that treat these babies at nine area hospitals, including four Scripps Health facilities, Palomar Medical Center and Pomerado Hospital, and Rancho Springs Medical Center in Murrieta.

The infants might also exhibit tremors or seizures, elevated heart and respiratory rate, or be difficult to feed, he said.

Between 55 percent and 94 percent of babies born to mothers who used opioids while pregnant will suffer symptoms of drug withdrawal.

At Sharp Mary Birch Hospital, where more babies are born than in any other California hospital (about 10,000 per year), and which reported 84 babies with positive toxicology screens in 2015, other conditions that can prompt drug screening include:

–Any history of substance abuse by the mother in the last three years.

–Fewer than the recommended four prenatal care visits.

–Problems with the placenta.

–A history of Child Protective Services involvement or a child in foster care.

Affected rate by county

The ratio of babies born to California parents affected by drugs transmitted by placenta or breast milk varies widely throughout the state, from a low of 3 out of every 1,000 babies in San Mateo County, to 49.7 out of every 1,000 babies in Shasta County. These numbers don't include babies affected who were not born in a hospital. Also does not include babies for whom parents reported a ZIP code that couldn't be matched with a California county.

Proactive screening

As a precaution, some San Diego area physician groups are “automatically getting urine toxicology screens on all of their moms, whether they are high risk or not,” said Rady neonatologist Dr. Richard Song. That’s to prevent any stigma “and not to show bias for who gets selected for urine toxicology screening.”

Dr. David Golembeski, neonatal services medical director at Palomar Medical Center, said his hospital has a “low threshold” for sending a baby’s urine or stool for toxicology testing, and some obstetrician groups are testing all pregnant women.

Song and Golembeski are also members of the UC San Diego faculty.

Song said concern that a baby may be affected by maternal drugs sometimes comes from nurses who say they “have a funny feeling ... I’m not comfortable with how this baby is acting. It’s not feeding well. It seems like this baby is going through withdrawal and the mom is acting funny.”

Screening also takes place “when there’s a social situation that’s not clear to us and the baby is not transitioning appropriately.”

Clinicians use a scoring system to gauge withdrawal severity, and when babies reach a certain number, treatment for withdrawal begins.

Why the jump?

Prince acknowledged the trend line is “very, very alarming” but couldn’t explain reasons for the sharp increase between 2014 and 2015, except that more people, including women, are being prescribed pain medications. “We’re seeing it in emergency rooms, we’re seeing it with overdoses. It’s illicit use with heroin and inappropriate prescription use as well.”

Maybe, he postulated, “we’re getting better at noticing it.”

A look at affected baby counts by quarter produces a clue. In counties with the largest number of affected infants, NAS cases rose disproportionately in the last quarter of 2015, which started Oct. 1, compared with the previous three.

Oct. 1, 2015, was when the nation converted its diagnostic coding from a system known as ICD-9 to the much more specific ICD-10. Perhaps the more explicit codes captured more categories of babies born to mothers on drugs.

National NAS research expert Dr. Stephen Patrick, assistant professor in pediatrics and health policy at Vanderbilt University in Nashville, Tennessee, couldn’t explain the change but said that under ICD-9, NAS cases were underestimated. ICD-10 “should make reporting more accurate.”

OSHPD spokesman David Byrnes said the agency highlighted the newborn data as one of two “DataBytes” it features each month for its “topical interest,” but did not analyze the numbers as to a cause for the greater rate of increase.

Officials with the California Perinatal Quality Care Collaborative and the California Maternal Quality Care Collaborative also could not explain the steep rise.

Nor could the California Department of Public Health, which pointed to a general “rise in the number and amount of prescription medications being prescribed and dispensed,” many of which are for opioid pharmaceuticals with the potential for abuse, and a “sharp rise” in heroin use since 2010. The department has launched several programs to prevent prescription drug overdoses and misuse.

Drug affected babies cost taxpayers dollars

No matter why the uptick in the last quarter of 2015, the consequences are real to families and taxpayers because most of these babies’ medical expenses are paid by Medicaid, or Medi-Cal as it’s known in California, using a combination of state and federal funds.

According to the National Institute on Drug Abuse, a baby suffering from withdrawal will likely endure “lengthy and costly hospital stays,” with an average of 17 days and a cost of $66,700, compared to 2.1 days and $3,500 for an unaffected baby.

The long-term outcomes for a newborn are less clear, but may include low birth weight, preterm delivery, smaller head circumference or visual disturbances.

“The thing we don’t really know yet is what (exposure to addictive drugs) does to babies long term,” Prince said.

Fears about negative impacts on babies whose mothers used crack cocaine or methamphetamine turned out to be ill-founded, he said. “But with opioids it’s probably going to be different, because we know babies exposed to long-term opioids — it does affect brain development, although the consequences of that we don’t yet know.

“We do know that promptly treating withdrawal is really important to maximize the best outcome.”

County Health & Human Services Agency spokesman Craig Sturak called the numbers alarming. He said in an email that several programs for pregnant and parenting women with substance abuse problems “have seen success in achieving drug-free births,” including “Women And Their Children (WATCh)” operated within the county Probation Department. WATCh provides probation supervision for women “to ensure their babies are born drug and alcohol-free.”
