No filters selected

The filters you have selected from various query interfaces will be stored here, in the 'Filter Cart'. The database will be queried using filters added to your 'Filter Cart', when multiple filters are defined, each will be executed using 'AND' logic, so with each filter that is applied the result set gets smaller.

From the 'Filter Cart' you can inspect each of the filters that have been defined, and you also have the option to remove filters. The 'Filter Cart' itself will display the number of filters applied along with the number of subjects that are identified by the combination of those filters. For example a GUID filter with two subjects, followed by a GUID filter for just one of those subjects would return only data for the subject that is in both GUID filters.

If you have a question about the filter cart, or underlying filters please contact the help desk at The NDA Help Desk

Early identification and service linkage for urban children with autism
Emily Feinberg 
Emerging evidence demonstrates that Autism Spectrum Disorder (ASD) can be reliably diagnosed by age two, and that early identification and intervention can improve outcomes. Low-income and minority children with ASD, however, are diagnosed later and experience greater delays in service provision than their white and more financially advantaged peers. Feasible, culturally appropriate interventions with broad scale-up potential are necessary to reduce this disparity. This R01 application builds upon pilot studies (Augustyn, HRSA R40 MC19928; Feinberg, AHRQ R03 HS22155) of an adapted version of Patient Navigation as means to reduce disparities in ASD diagnosis and service provision. Patient Navigation is a lay-delivered case management approach that focuses on overcoming logistical hurdles to care during a defined episode. Pilot data from our research group demonstrate the feasibility of an adapted approach of Patient Navigation, referred to as Family Navigation (FN), among families of children with suspected ASD, and provide suggestive evidence that the approach both reduces time to ASD diagnosis and increases engagement with services. We propose a multisite, randomized comparative effectiveness trial (n=19,500) of a systemic, lay-delivered FN protocol, which begins prior to a child's 18 or 24 month health supervision visit and ends 100 days after an ASD diagnosis is made. The trial takes place in urban, integrated care networks that provide healthcare to low-income children. The basic structure of both intervention arms is a collaborative care system. The conventional care management arm (CCM) is consistent with the type of care provided within a traditional - but high quality - medical home. The FN arm provides more intensive, individually tailored, care coordination and theory-based family support. Children will be followed for 12 months. Data regarding screening outcomes, diagnosis and service utilization will be abstracted from children's medical records. Measures of parental stress, self-management skills, caregiver burden, and satisfaction with services will be administered over 4 collection time points, linked to key intervention outcomes. We will assess the superiority of FN as compared to CCM as a means to: achieve an 80% screening rate for indicators of ASD across all sites; implement a decision rule for referral to ASD evaluation; shorten the time to diagnosis among children suspected to have ASD; shorten the time to deployment of ASD services among those diagnosed; and improve engagement with ASD services. Our lay-delivered FN system has been designed to have broad scale-up potential. Thus, to provide critical information on how such a system could be best implemented and disseminated across urban primary care settings nationwide, we will conduct a concurrent implementation analysis - systematically examining performance gaps in FN's delivery according to the Theoretical Domains Framework. If successful, our study will provide real world primary care practices with a replicable model of care that increases early identification and access to timely diagnostic and early intervention services for a vulnerable population of urban families.

Associated Studies

Studies that have been defined using data from a Collection are important criteria to determine the value of data shared. The number of subjects column displays the counts from this Collection that are included in a Study, out of the total number of subjects in that study. The Data Use column represents whether or not the study is a primary analysis of the data or a secondary analysis. State indicates whether the study is private or shared with the research community.
