Using the ATra Black Box to Improve Public Health Data Linkages and Analytics in the DC Cohort Longitudinal HIV Study: Viewpoint on the Process and Findings

Using the ATra Black Box to Improve Public Health Data Linkages and Analytics in the DC Cohort Longitudinal HIV Study: Viewpoint on the Process and Findings

While the linkage is a unique aspect of the DC Cohort, the process of linking data using complex SAS coding took an estimated 6 months to complete, thereby limiting the timeliness and utility of the linked data. To increase the ease, feasibility, accuracy, and timeliness of future linkages, the DC Cohort sought to identify a more efficient approach to data linkage and analysis.

Evidence on Digital HIV Self-Testing From Accuracy to Impact: Updated Systematic Review

Evidence on Digital HIV Self-Testing From Accuracy to Impact: Updated Systematic Review

Observed in 46.6% (21/45) of studies [4,22,24,29,31,33-35,40,42,43,45-49,53,55,57,62,64]. 76.2% (16/21) of these studies reported this metric as confirmatory HIV testing and linkage to treatment which varied from 53.0%-100.0% [22,24,29,31,33-35,40,42,45,47,53,55,57,62]. Out of 8 studies (38.0%) reported linkage to care as the percent of confirmed HIV-positive participants who were referred to and initiated antiretroviral therapy (ART) and ranged from 44.4%-98.1% [4,43,46,48,49,53,55,64].

The University of California Study of Outcomes in Mothers and Infants (a Population-Based Research Resource): Retrospective Cohort Study

The University of California Study of Outcomes in Mothers and Infants (a Population-Based Research Resource): Retrospective Cohort Study

Accurate linkages were prioritized over high linkage rates; therefore, a pessimistic linkage method was used to increase the likelihood of true matches.

The Automatic Context Measurement Tool (ACMT) to Compile Participant-Specific Built and Social Environment Measures for Health Research: Development and Usability Study

The Automatic Context Measurement Tool (ACMT) to Compile Participant-Specific Built and Social Environment Measures for Health Research: Development and Usability Study

The second interface, which is more friendly to layman users and avoids requiring the data analyst to write R code, uses RShiny-based helper screens to guide analysts through a process by which they open a file of locations (eg, street addresses), geocode them, specify a data set, a neighborhood radius and years of data to spatially link, allowing the ACMT to perform the appropriate data download, spatial linkage, and interpolation for the analyst’s data set of interest.

Development of Indirect Health Data Linkage on Health Product Use and Care Trajectories in France: Systematic Review

Development of Indirect Health Data Linkage on Health Product Use and Care Trajectories in France: Systematic Review

As quality assessment of data linkage is essential to limit biased results and false interpretation, several recommendations highlight elements or information about the linkage pathway (data provision, method of data linkage, and data analyses) to be shared and checked [4,22]. In this context, the objective of this systematic review is to analyze the type and quality of research publications on indirect data linkage on health product use and care trajectories in France.
