MILWAUKEE – A new study of for them.

The Medicaid claims database analysis looked at a one-year snapshot of prescriptions filled for a variety of opioids among children and young adults in North Carolina, said Nancy Crego, PhD, in an interview at a poster session of the scientific meeting of the American Pain Society.
Dr. Crego and her colleagues at Duke University School of Nursing, Durham, N.C., studied 1,560 children and young adults aged 0-22 years with sickle cell disease who received Medicaid; in all, 586 (38%) had an opioid prescription filled during the year-long study period.
Among adolescents and young adults with sickle cell disease, outpatient opioid prescriptions were common, with increasing prescription fills seen through the middle years and young adulthood. “Opioid prescription claims were prevalent across all age groups,” wrote Dr. Crego and her associates.
Though 20% of preschoolers (87 of 428) had had a prescription filled for opioids, the rates of opioid prescribing increased with age. Of adolescents aged 15-18 years, 54% (154 of 284) had filled an opioid prescription, as had 50% (110 of 221) of those aged 19-22 years.
For the 366 school-aged children aged 6-10 years, 117 (32%) had an opioid prescription filled. The number of prescriptions filled per patient on an annual basis for this age group ranged from one to 10.
There was a wide variation in the number of prescriptions filled in all other age groups over the study period as well. For school-aged children, the range was 1 to 10, and 1 to 18 for middle schoolers aged 11-14 years. Adolescents filled from 1-30 prescriptions, and for young adults, the range was 1-24.
Though the rates of opioid prescribing increased with age, the number of doses per prescription actually fell throughout the adolescent and young adult years. In an interview at the poster presentation, Dr. Crego speculated that this decrease observed with increasing age might reflect provider concern about opioid misuse and diversion, though the study methodology didn’t allow them to examine this.
Dr. Crego said that she was surprised by the high numbers of children who were receiving opioid prescriptions in the preschool years. “I wonder what their parents are being taught about how to administer these medications” to this very young age group, she commented.
Opioids included in the claims database analysis included morphine, hydromorphone, hydrocodone, oxycodone, oxymorphone, methadone, fentanyl, codeine, and tramadol.
Children with sickle cell disease are exposed to opioids in early childhood,” Dr. Crego and her colleagues wrote in the poster, but they acknowledged that “it is unknown if this early exposure increases the risk of opioid misuse later in life in this population ... Prescribers should incorporate continuous assessments for potential misuse and abuse in all age groups.”
“Most of the data that we have on opioid prescription claims in children usually exclude chronically ill children; they’re almost all of acutely ill children, and quite a bit of it is on postoperative care,” Dr. Crego said. The current study captures early-life prescribing “for somebody who’s going to be on opioids for a lot of their life,” she noted.
The studies of opioids used for acute pain, she said, showed that parents would often “administer opioids for inappropriate indications.” She is now conducting a qualitative study investigating pharmacologic and non-pharmacologic pain interventions for children with sickle cell disease. She’s also investigating how parents decide to administer opioids: “What did they see in their child that would prompt them to give an opioid versus giving another type of analgesic?”
There are some limitations to working with a claims database, acknowledged Dr. Crego: “We don’t know about their actual use, because we don’t know how often they are taking it, but we know it’s a filled opioid prescription.”
Dr. Crego said that more work is needed to examine how parents administer opioids to their children with sickle cell disease, and to learn more about what parents are told – and what they understand – about how their child’s pain should be managed. Also, she added, more research is needed on non-pharmacologic pain management for pediatric patients with sickle cell disease.
The study was funded by the Agency for Healthcare Research and Quality. Dr. Crego and her coauthors reported no conflicts of interest.
