CONTEXT: Transition from the pediatric to the adult health care system is a complex process that should include medical, psychosocial, educational, recreational, and vocational considerations. OBJECTIVE: In this systematic review, we aim to synthesize the evidence on transitional care interventions (TCIs) to improve the quality of life (QoL) for adolescents and young adults with childhood-onset disabilities, including neurodevelopmental disorders. DATA SOURCES: Four electronic databases (Medline, Embase, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature) were searched. STUDY SELECTION: In the included studies, researchers examined TCIs for adolescents and young adults (12-24 years of age) with childhood-onset disabilities. Studies were experimental, quasi-experimental, and observational studies published in the last 26 years. DATA EXTRACTION: Two reviewers independently completed study screening, data extraction, and risk-of-bias assessment. RESULTS: Fifty-two studies were included. Five studies reported on QoL, but statistically significant improvements were noted in only 1 of these studies. Significant improvements were also found in secondary outcomes including disability-related knowledge and transitional readiness. TCIs targeted patients, families and/or caregivers, and health care providers and exhibited great heterogeneity in their characteristics and components. LIMITATIONS: Inconsistent reporting on interventions between studies hindered synthesis of the relationships between specific intervention characteristics and outcomes. CONCLUSIONS: Although there is limited evidence on the impact of TCIs on the QoL for youth with childhood-onset disabilities, there is indication that they can be effective in improving patient and provider outcomes. The initiation of transition-focused care at an early age may contribute to improved long-term health outcomes in this population.
Williams syndrome (WS) is a well-known genetic disorder with a variable phenotype. In many cases, physical manifestations are subtle and may not be apparent at an early age, making diagnosis difficult in infants and young children who lack classic manifestations such as supravalvular aortic stenosis and hypercalcemia. Clinical suspicion is essential because the diagnostic genetic finding is not detectable on routine chromosomal analysis. Furthermore, early diagnosis allows for earlier detection and treatment of developmental, behavioral, and medical problems. In an effort to understand how and why individuals with WS are diagnosed, we conducted a survey-based study of parents of WS children. Packets containing a cover letter, consent form, parental survey and preaddressed stamped envelope were distributed to parents of children with WS. The survey included questions concerning initial diagnosis, WS findings present, medical specialists involved, and tests performed. Forty-six completed surveys were returned for analysis. The mean age at diagnosis was 3.66 years (SD 4.13). The mean age at which there were initial concerns was 0.98 year (SD 1.24) resulting in a mean delay in diagnosis of 2.77 years (SD 4.10). In addition, the involvement of a geneticists correlated with earlier diagnosis (2.26 years vs. 5.09 years without geneticist involvement, p = 0.03) and fewer tests ordered (5.2 vs. 8.2 in the nongeneticist group, p = 0.0006). We observed a significant delay in the diagnosis of WS. Of note, the involvement of a geneticist was associated with earlier diagnosis and reduced number of tests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
