Misdiagnosis and missed diagnoses in foster and adopted children with prenatal alcohol exposure.

The purpose of this article is to assess the rate of misdiagnosis and missed diagnoses of fetal alcohol spectrum disorders (FASD) among a population of foster and adopted youth referred to a children's mental health center. Data were collected from a sample of 547 children who underwent a comprehensive multidisciplinary diagnostic evaluation. Utilizing current diagnostic criteria, children were diagnosed, as appropriate, with fetal alcohol syndrome, partial fetal alcohol syndrome, alcohol-related neurodevelopmental disorder, or alcohol-related birth defects. Changes in rates of alcohol exposure-related diagnoses and cooccurring mental health disorders pre- and postassessment were analyzed by using McNemar's test for dependent proportions. Among 156 children and adolescents who met criteria for a diagnosis within the fetal alcohol spectrum, 125 had never been diagnosed as affected by prenatal alcohol exposure, a missed diagnosis rate of 80.1%. Of the 31 who had been recognized before referral as affected by prenatal alcohol exposure, 10 children's FASD diagnoses were changed within the spectrum, representing a misdiagnosis rate of 6.4%. The remaining 21 (13.5%) children's diagnoses stayed the same. There also were significant changes in the rate of mental health diagnosis, and learning disorders, communication disorders, and intellectual disability, objective signs of neurocognitive damage, were not recognized in a significant number of children with FASD. Within this clinical sample, 86.5% of youth with FASD had never been previously diagnosed or had been misdiagnosed. These high rates of missed diagnoses and misdiagnosis have significant implications for intervention and therapeutic services.

Neurodevelopmental Functioning in Children With FAS, pFAS, and ARND

The purpose of this article is to compare the neurodevelopmental profiles of 78 foster and adopted children with fetal alcohol syndrome (FAS), partial FAS (pFAS), or alcohol-related neurodevelopmental disorder (ARND). Seventy-eight foster and adopted children underwent a comprehensive diagnostic evaluation. By using criteria more stringent than those required by current guidelines, the children were placed in 1 of 3 diagnostic categories: FAS, pFAS, or ARND. Each child was evaluated across the domains of neuropsychological functioning most frequently affected by prenatal exposure to alcohol. Multivariate analyses of variance were conducted to examine differences in neuropsychological functioning between the 3 diagnostic groups. Descriptive discriminant analyses were performed in follow-up to the multivariate analyses of variance. The children in the 3 diagnostic categories were similar for descriptive and child welfare variables. Children with FAS had significantly decreased mean weight, height, and head circumference. Children with FAS exhibited the most impaired level of general intelligence, significantly worse language-based memory compared with children with ARND, and significantly poorer functional communication skills than children with pFAS. On executive functioning, the FAS group of children performed significantly worse on sequencing and shift than either the pFAS or ARND groups. Children with pFAS and ARND were similar in all neurodevelopmental domains that were tested. The children who met tightly defined physical criteria for a diagnosis of FAS demonstrated significantly poorer neurodevelopmental functioning than children with pFAS and ARND. Children in these latter 2 groups were similar in all neurodevelopmental domains that were tested.

Commentary: screening as a tool for engagement

We wish to thank Dr Hendree E Jones for her thoughtful commentary1 regarding our article, 'The 4P's Plus© Screen for Substance Use in Pregnancy: Clinical Application and Outcomes.'2 Because the article focused on data generated through the use of the 4P's Plus© to screen for alcohol, tobacco and illicit drug use in pregnancy, there was nothing presented regarding the practical, public health goals served by the use of the screening instrument. In the best of circumstances, the 4P's Plus© is utilized in the context of a much larger integrated system of screening, assessment, referral and treatment – the SART system.3 Prior to implementing screening in any community, we establish guidelines and policies that allow for conducting a field assessment4 in the prenatal care setting on any woman who screens 'positive'. The screen identifies women who are at risk for substance use; the field assessment identifies women who actually are continuing to use alcohol, tobacco or illicit drugs during their pregnancy and require further intervention. Although quantity and frequency of substance use would be interesting, busy obstetric practices do not have the time for that depth of investigation. In addition, these factors are of little importance in the screening process; the job of the primary care provider is to identify women at risk so that they can be referred for further interventions. The screening and field assessment, which occur in the prenatal care site, are easy, fast (less than 5 min) and are used to link the woman to a single community-based referral mechanism through which the woman accesses treatment. In this context, the 4P's Plus© screen takes its place as the trigger event for a coordinated response to perinatal substance use. In practice, we work with communities to establish a full process of which screening and assessment are just an initial component.

The 4P's Plus© Screen for Substance Use in Pregnancy: Clinical Application and Outcomes

Determine the prevalence of substance use among pregnant women in five diverse communities utilizing the 4P's Plus screen for alcohol, tobacco, and other drug use. Pregnant women enrolled in prenatal care clinics in five communities were screened for substance use with the 4P's Plus. Those women with a positive screen underwent an assessment for substance use through a follow-up structured clinical interview conducted at the same prenatal visit. Among 7818 women in five communities, 2555 (32.7%) had a positive screen for substance use in pregnancy. Four of the communities conducted a follow-up assessment on all women with a positive screen (n = 1548). Among these women, 717 (15% of the total population) had continued use after learning of the pregnancy. Overall, 21% of the pregnant women used alcohol prior to recognition of the pregnancy, and 11% continued use after knowledge of the pregnancy. Among the 512 women who continued to use alcohol, 2% were drinking daily, 7% were drinking 3 to 6 days per week, 27% were drinking 1 to 2 days per week, and 63% were drinking less than 1 day per week. The rates of marijuana use and other illicit drug use among the women were 7 and 2%, respectively, prior to knowledge of pregnancy and dropped to 3 and 1% after learning of the pregnancy. The 4P's Plus identifies not only those pregnant women whose drinking or drug use is at a high enough level to impair daily functioning, but provides an opportunity for early intervention for the much larger group of women whose pregnancies are at risk from relatively small amounts of substance use.
