Hospitals Rethink Routine Newborn Drug Testing Policies Nationwide

A growing number of doctors and hospitals are challenging long-standing practices of routine drug testing during childbirth, arguing that the tests often cause more harm than good and fail to improve medical care for newborns.

Dr. Sharon Ostfeld-Johns, a physician at Yale New Haven Health in Connecticut, recently refused a request from child welfare authorities to drug test a newborn whose mother had used marijuana during pregnancy. Though the infant was healthy, the hospital had previously reported the mother to authorities. Ostfeld-Johns questioned whether the test was medically necessary and whether it could trigger unnecessary investigations into the family, particularly given the racial and socioeconomic biases in child welfare systems.

After reviewing her own experience—learning she had been drug tested without consent during her own pregnancy—Ostfeld-Johns led an effort to reform Yale New Haven’s drug testing policies in 2022. The new guidelines direct doctors to test newborns only when results would directly inform medical care, a rare scenario. The hospital also established stricter criteria for testing pregnant patients. Preliminary data shows that after the policy change, child welfare referrals from the newborn nursery dropped nearly 50 percent without any increase in untreated withdrawal symptoms among babies.

This shift reflects a broader trend. Across the U.S., hospitals are re-evaluating policies that have been standard for decades. Many began widespread drug testing during the crack cocaine epidemic of the 1980s and expanded the practice during the opioid crisis. While federal law requires hospitals to notify child welfare agencies when a baby is born "affected by" substances, it does not mandate drug testing. Yet hospitals often test mothers and infants anyway, fearing legal or professional repercussions if they fail to identify potential risks.

Critics argue that drug tests are unreliable for medical decisions. Urine tests, the most commonly used method, have high false-positive rates—up to 50 percent in some cases—due to factors like poppy seeds, prescribed medications, or even epidural fentanyl. Studies show that low-income, Black, Latina, and Indigenous women are disproportionately subjected to these tests, reinforcing racial and economic disparities in child welfare investigations.

Dr. Christine Gold, a pediatrician in Colorado, emphasizes that toxicology results do not assess parenting ability or addiction severity. "Drug tests are not parenting tests," she said. "They tell us little about a parent’s capacity to care for a child."

Hospitals that have reduced testing report similar outcomes. At UMass Memorial Medical Center in Massachusetts, doctors eliminated automatic newborn drug testing in 2024. Director of the newborn nursery Dr. Mark Vining said the change led to fewer child welfare referrals without missing cases of withdrawal that required treatment.

The emerging approach prioritizes direct communication with patients over punitive testing. While legislation remains limited, voluntary policy changes are spreading. In Colorado, advocacy groups have distributed new guidelines to hospitals, while national initiatives like "Doing Right by Birth" educate healthcare providers on legal requirements and alternatives to testing.

As more institutions adopt these reforms, they challenge an entrenched system that has long conflated medical care with surveillance. For doctors like Ostfeld-Johns, the shift is about reducing harm. "The hurt that we do to people is overwhelming," she said. "We should focus on what actually helps families."
