With onset often occurring before 6 years of age, attention-deficit/hyperactivity disorder (ADHD) involves attention problems, impulsivity, overactivity, and sometimes disruptive behavior. Impairment usually persists into adulthood, with an estimated worldwide prevalence in adults of 2.5%. Existing gaps in evidence concerning ADHD hinder decision-making about treatment. This article describes and prioritizes future research needs for ADHD in three areas: treatment effectiveness for at-risk preschoolers; long-term treatment effectiveness; and variability in prevalence, diagnosis, and treatment. Using a recent systematic review concerning ADHD completed by a different evidence-based practice center as a foundation, we worked with a diverse group of 12 stakeholders, who represented researchers, funders, healthcare providers, patients, and families, to identify and prioritize research needs. From an initial list of 29 evidence gaps, we enumerated 8 high-priority research needs: a) accurate, brief standardized diagnosis and assessment; b) comparative effectiveness and safety of pharmacologic treatments for children under 6 years of age; c) comparative effectiveness of different combinations of psychosocial and pharmacologic treatments for children under 6 years of age; d) case identification and measurement of prevalence and outcomes; e) comparative effectiveness of psychosocial treatment alone versus pharmacologic and combination treatments for children under 6 years of age; f) comparative long-term treatment effectiveness for people 6 years of age and older; g) relative efficacy of specific psychosocial program components for children under 6 years of age; and h) identification of person-level effect modifiers for people 6 years of age and older. In this article, we describe these future research needs in detail and discuss study designs that could be used to address them. (Journal of Psychiatric Practice 2014;20:104–117)

The use of antipsychotics, particularly second generation antipsychotics, among children and adolescents has increased markedly during the past 20 years. Existing evidence gaps make this practice controversial and hinder treatment decision-making. This article describes and prioritizes future research needs regarding antipsychotic treatment in youth, focusing on within-class and between-class drug comparisons with regard to key population subgroups, efficacy and effectiveness outcomes, and adverse event outcomes. Using as a foundation a recent systematic review of antipsychotic treatment among youth, which was completed by a different Evidence-based Practice Center, we worked with a diverse group of 12 stakeholders representing researchers, funders, health care providers, patients, and families to identify and prioritize research needs. From an initial list of 16 evidence gaps, we enumerated 6 high-priority research needs: 1) long-term comparative effectiveness across all psychiatric disorders; 2) comparative long-term risks of adverse outcomes; 3) short-term risks of adverse events; 4) differentials of efficacy, effectiveness, and safety for population subgroups; 5) comparative effectiveness among those with attention-deficit/hyperactivity disorder and disruptive behavior disorders and common comorbidities; 6) comparative effectiveness among those with bipolar disorder and common comorbidities. In this article, we describe these future research needs in detail and discuss study designs that could be used to address them. (Journal of Psychiatric Practice 2015;21:26–36)

BackgroundSome outcomes for children with mental health problems remain suboptimal because of poor access to care and the failure of systems and providers to adopt established quality improvement strategies and interventions with proven effectiveness. This review had three goals: (1) assess the effectiveness of quality improvement, implementation, and dissemination strategies intended to improve the mental health care of children and adolescents; (2) examine harms associated with these strategies; and (3) determine whether effectiveness or harms differ for subgroups based on system, organizational, practitioner, or patient characteristics.MethodsSources included MEDLINE®, the Cochrane Library, PsycINFO, and CINAHL, from database inception through February 17, 2017. Additional sources included gray literature, additional studies from reference lists, and technical experts. Two reviewers selected relevant randomized controlled trials (RCTs) and observational studies, extracted data, and assessed risk of bias. Dual analysis, synthesis, and grading of the strength of evidence for each outcome followed for studies meeting inclusion criteria. We also used qualitative comparative analysis to examine relationships between combinations of strategy components and improvements in outcomes.ResultsWe identified 18 strategies described in 19 studies. Eleven strategies significantly improved at least one measure of intermediate outcomes, final health outcomes, or resource use. Moderate strength of evidence (from one RCT) supported using provider financial incentives such as pay for performance to improve the competence with which practitioners can implement evidence-based practices (EBPs). We found inconsistent evidence involving strategies with educational meetings, materials, and outreach; programs appeared to be successful in combination with reminders or providing practitioners with newly collected clinical information. We also found low strength of evidence for no benefit for initiatives that included only educational materials or meetings (or both), or only educational materials and outreach components. Evidence was insufficient to draw conclusions on harms and moderators of interventions.ConclusionsSeveral strategies can improve both intermediate and final health outcomes and resource use. This complex and heterogeneous body of evidence does not permit us to have a high degree of confidence about the efficacy of any one strategy because we generally found only a single study testing each strategy.Trial registrationPROSPERO, CRD42015024759.

OBJECTIVE The rise in use of antipsychotics among U.S. children is well documented. Compliance rates with current safety-monitoring guidelines are low. In response, the North Carolina Division of Medical Assistance established the Antipsychotics-Keeping It Documented for Safety (A+KIDS) registry. The initial objectives of the project were to successfully establish a Web-based safety registry and to obtain and evaluate clinical information derived from the registry. METHODS In April 2011, A+KIDS began asking prescribers of antipsychotics for children age 12 and under to respond to a set of questions regarding dose, indication, and usage history. Antipsychotic registrations were examined by linking North Carolina Medicaid prescription claims to registry entries. Prescribers were classified into different types, and the number of patients and registrations per prescriber were examined. RESULTS In the initial six months, 730 prescribers registered 5,532 patients, 19% below age seven. By month 6 of the registry, 72% of all fills were registered with the program. Top diagnosis groups for registry patients were unspecified mood disorders, autism spectrum disorders, and disruptive behavior disorders. Top target symptoms were aggression (48%), irritability (19%), and impulsivity (11%). Psychosis accounted for 5% of the target symptoms. Twenty-eight percent of children were receiving no form of psychotherapy. Twenty-five percent of all A+KIDS prescribers were responsible for 81% of the registrations. CONCLUSIONS The A+KIDS registry initiative has been successful, as measured by rapid uptake, and is providing clinical information not available from claims data alone. Future efforts will allow for detailed examinations of antipsychotic utilization and further safety improvement.

Repetitive sensory motor behaviors are a direct target for clinical treatment and a potential treatment endpoint for individuals with intellectual or developmental disabilities. By removing the burden associated with video annotation or direct observation, automated detection of stereotypy would allow for longer term monitoring in ecologic settings. We report automated detection of common stereotypical motor movements using commercially available accelerometers affixed to the body and a generalizable detection algorithm. The method achieved a sensitivity of 80% for body rocking and 93% for hand flapping without individualized algorithm training or foreknowledge of subject’s specific movements. This approach is well-suited for implementation in a continuous monitoring system outside of a clinical setting.
