Computer Adaptive Testing Approach to Patient-Reported Outcomes

Posted on by Gina Uhlenbrauck

Michael Bass and Maria Varela Diaz of the Department of Social Sciences, Feinberg School of Medicine, Northwestern University, have kindly given the Living Textbook permission to post their presentation (link opens as a PDF) about how to use an application programming interface (API) to create a computer adaptive testing (CAT) program that integrates patient-reported outcome (PRO) measures with an institution’s electronic health record (EHR) system.

With a CAT approach, PRO assessment can cover a wide range of question/response items with increased precision. In their CAT application, the authors describe a clinical use case for a mobile health solution, using measures from the NIH-sponsored PRO Measurement Information System (PROMIS®) domain framework, in which a health assessment is issued by a physician, administered to a patient via phone, and then sent back to the EHR.

You can read more about CAT in the Patient-Reported Outcomes chapter of the Living Textbook.

Collaboratory Phenotypes, Data Standards, and Data Quality Core Releases Data Quality Assessment White Paper

Posted on by Gina Uhlenbrauck

The NIH Collaboratory’s Phenotypes, Data Standards, and Data Quality Core (now the Electronic Health Records Core) has released a new white paper on data quality assessment in the setting of pragmatic research. The white paper, titled Assessing Data Quality for Healthcare Systems Data Used in Clinical Research (V1.0) provides guidance, based on the best available evidence and practice, for assessing data quality in pragmatic clinical trials (PCTs) conducted through the Collaboratory. Topics covered include an overview of data quality issues in clinical research settings, data quality assessment dimensions (completeness, accuracy, and consistency), and a series of recommendations for assessing data quality. Also included as appendices are a set of data quality definitions and review criteria, as well as a data quality assessment plan inventory.

The full text of the document can be accessed through the “Tools for Research” tab on the Living Textbook or can be downloaded directly here (PDF).
