Clinical Data Reuse or Secondary Use: Current Status and Potential Future Progress
Objective: To perform a review of recent research in clinical data reuse or secondary use, and envision future advances in this field. Methods: The review is based on a large literature search in MEDLINE (through PubMed), conference proceedings, and the ACM Digital Library, focusing only on research published between 2005 and early 2016. Each selected publication was reviewed by the authors, and a structured analysis and summarization of its content was developed. Results: The initial search produced 359 publications, reduced after a manual examination of abstracts and full publications. The following aspects of clinical data reuse are discussed: motivations and challenges, privacy and ethical concerns, data integration and interoperability, data models and terminologies, unstructured data reuse, structured data mining, clinical practice and research integration, and examples of clinical data reuse (quality measurement and learning healthcare systems). Conclusion: Reuse of clinical data is a fast-growing field recognized as essential to realize the potentials for high quality healthcare, improved healthcare management, reduced healthcare costs, population health management, and effective clinical research
Cohort discovery and risk stratification for Alzheimer’s disease: an electronic health record‐based approach
BackgroundWe sought to leverage data routinely collected in electronic health records (EHRs), with the goal of developing patient risk stratification tools for predicting risk of developing Alzheimer’s disease (AD).MethodUsing EHR data from the University of Michigan (UM) hospitals and consensus‐based diagnoses from the Michigan Alzheimer’s Disease Research Center, we developed and validated a cohort discovery tool for identifying patients with AD. Applied to all UM patients, these labels were used to train an EHR‐based machine learning model for predicting AD onset within 10 years.ResultsApplied to a test cohort of 1697 UM patients, the model achieved an area under the receiver operating characteristics curve of 0.70 (95% confidence interval = 0.63‐0.77). Important predictive factors included cardiovascular factors and laboratory blood testing.ConclusionRoutinely collected EHR data can be used to predict AD onset with modest accuracy. Mining routinely collected data could shed light on early indicators of AD appearance and progression.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/155901/1/trc212035-sup-0001-SuppMat.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155901/2/trc212035_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155901/3/trc212035.pd
Decision Support Based on Bio-PEPA Modeling and Decision Tree Induction: A New Approach, Applied to a Tuberculosis Case Study
The problem of selecting determinant features generating appropriate model structure is a challenge in epidemiological modelling. Disease spread is highly complex, and experts develop their understanding of its dynamic over years. There is an increasing variety and volume of epidemiological data which adds to the potential confusion. We propose here to make use of that data to better understand disease systems. Decision tree techniques have been extensively used to extract pertinent information and improve decision making. In this paper, we propose an innovative structured approach combining decision tree induction with Bio-PEPA computational modelling, and illustrate the approach through application to tuberculosis. By using decision tree induction, the enhanced Bio-PEPA model shows considerable improvement over the initial model with regard to the simulated results matching observed data. The key finding is that the developer expresses a realistic predictive model using relevant features, thus considering this approach as decision support, empowers the epidemiologist in his policy decision making

Self-supervised learning-based general laboratory progress pretrained model for cardiovascular event detection
The inherent nature of patient data poses several challenges. Prevalent cases
amass substantial longitudinal data owing to their patient volume and
consistent follow-ups, however, longitudinal laboratory data are renowned for
their irregularity, temporality, absenteeism, and sparsity; In contrast,
recruitment for rare or specific cases is often constrained due to their
limited patient size and episodic observations. This study employed
self-supervised learning (SSL) to pretrain a generalized laboratory progress
(GLP) model that captures the overall progression of six common laboratory
markers in prevalent cardiovascular cases, with the intention of transferring
this knowledge to aid in the detection of specific cardiovascular event. GLP
implemented a two-stage training approach, leveraging the information embedded
within interpolated data and amplify the performance of SSL. After GLP
pretraining, it is transferred for TVR detection. The proposed two-stage
training improved the performance of pure SSL, and the transferability of GLP
exhibited distinctiveness. After GLP processing, the classification exhibited a
notable enhancement, with averaged accuracy rising from 0.63 to 0.90. All
evaluated metrics demonstrated substantial superiority (p < 0.01) compared to
prior GLP processing. Our study effectively engages in translational
engineering by transferring patient progression of cardiovascular laboratory
parameters from one patient group to another, transcending the limitations of
data availability. The transferability of disease progression optimized the
strategies of examinations and treatments, and improves patient prognosis while
using commonly available laboratory parameters. The potential for expanding
this approach to encompass other diseases holds great promise.Comment: published in IEEE Journal of Translational Engineering in Health &
