Development and Evaluation of a Virtual Model for Fetal Alcohol Spectrum Disorder (FASD) Assessment and Diagnosis in Children: A Pilot Study.

The diagnostic process for fetal alcohol spectrum disorder (FASD) involves a multi-disciplinary team and includes neurodevelopmental, physical, and facial assessments and evidence of prenatal alcohol exposure during the index pregnancy. With the increased use of virtual care in health care due to the pandemic, and desire of clinics to be more efficient when providing timely services, there was a need to develop a virtual diagnostic model for FASD. This study develops a virtual model for the entire FASD assessment and diagnostic process, including individual neurodevelopmental assessments. It proposes a virtual model for assessment and diagnosis of FASD in children and evaluates the functionality of this model with other national and international FASD diagnostic teams and caregivers of children being assessed for FASD.

Assessing for Fetal Alcohol Spectrum Disorder.

Background The recommended "gold standard" for Fetal Alcohol Spectrum Disorder (FASD) assessment involves a multidisciplinary diagnostic team and comprehensive battery of neuropsychological tests to evaluate functioning across 10 brain domains. The current Canadian Guideline for diagnosis of FASD outlines a list of test measures for assessment; however, very little research exists to explore which specific tools are being used in clinical practice. Objectives The purpose of the current study was to gain a better understanding of the testing measures used by FASD clinicians in Alberta, Canada.   Methods A survey was sent to coordinators of 23 Alberta FASD clinics requesting them to distribute the survey to their diagnostic team members, including physicians, psychologists, speech-language pathologists (SLPs), and occupational therapists (OTs).   Results A wide range of measures (both direct and indirect; n = 173) to assess brain domains were reported by clinics. Many tests were used to assess function across multiple brain domains. Most of the commonly used tests aligned with those suggested in the Canadian Guideline; however, there were many additional measures being used that were that were not listed in the Guideline.   Conclusions This study revealed important information about the use of testing measures in FASD assessment and sheds light on the commonalities in practice across clinics in Alberta. Results demonstrate strong convergence of direct and indirect measures to assess brain function. Ultimately, identifying a comprehensive, reliable, and usable testing battery of measures for FASD assessment will improve the clarity and accuracy of the diagnostic process and facilitate advancements in the field, as well as enable comparisons across clinics.

Deferred diagnosis in children assessed for fetal alcohol spectrum disorder.

Early intervention for individuals with FASD is paramount, thus exploring factors that affect the diagnostic process is critical. This process can be complicated by challenges gathering background information, accurately evaluating higher-level cognitive skills across ages, and teasing apart the impact of life adversities from the effects of prenatal alcohol exposure. This study is a retrospective file review of 154 children (44% female; mean age 8.4 years, range 1.0 to 16.9) deferred at their first FASD assessment, and 51 (43% female; mean 9.9 years, range 2.7 to 17.2) who returned for a second assessment. Data was collected from three Canadian FASD clinics to explore reasons for deferral, the clinical profile of deferred children, why some returning children were diagnosed while others were not, and changes between assessments. Results suggest that deferred children initially lacked evidence of abnormalities sufficient for a diagnosis, presented with areas of relative neurobehavioral strength and difficulty, and children eventually diagnosed with FASD showed significantly more impaired brain function (p < 0.001, ηp2 = 0.547), postnatal risk (p = 0.021, ηp2 = 0.121), and comorbidities (p = 0.038, ηp2 = 0.085) than undiagnosed children. These findings provide important insights into the process of clinical assessment for FASD.
