Patient Recruitment Using Electronic Health Records Under Selection Bias: a Two-phase Sampling Framework

  title={Patient Recruitment Using Electronic Health Records Under Selection Bias: a Two-phase Sampling Framework},
  author={Guanghao Zhang and Lauren J. Beesley and Bhramar Mukherjee and Xu Shi},
  journal={arXiv: Methodology},
Electronic health records (EHRs) are increasingly recognized as a cost-effective resource for patient recruitment for health research. Suppose we want to conduct a study to estimate the mean or mean difference of an expensive outcome in a target population. Inexpensive auxiliary covariates predictive of the outcome may often be available in patients' health records, presenting an opportunity to recruit patients selectively and estimate the mean outcome efficiently. In this paper, we propose a…

Handling Non-ignorably Missing Features in Electronic Health Records Data Using Importance-Weighted Autoencoders

A novel extension of VAEs called Importance-Weighted Autoencoders (IWAEs) is proposed to flexibly handle Missing Not At Random (MNAR) patterns in the Physionet data, which leads to more realistic imputed values relative to the state-of-the-art, as well as significant differences in fitted downstream models for mortality.



Selective recruitment designs for improving observational studies using electronic health records

A simple selective recruitment protocol is proposed that selects a cohort in which covariates of interest tend to have a uniform distribution and it is shown that selectively recruited cohorts potentially offer greater statistical power and more accurate parameter estimates than randomly selected cohorts.

Illustrating Informed Presence Bias in Electronic Health Records Data: How Patient Interactions with a Health System Can Impact Inference

It is illustrated that how a patient interacts with a health system influences which data are recorded in the EHR, and the overall set of induced biases informed presence is illustrated.

Active Use of Electronic Health Records (EHRs) and Personal Health Records (PHRs) for Epidemiologic Research: Sample Representativeness and Nonresponse Bias in a Study of Women During Pregnancy

The PHR may be an efficient method for recruiting and conducting observational research with additional benefits of efficiency and cost-cost-effectiveness.

Outcome‐dependent sampling for longitudinal binary response data based on a time‐varying auxiliary variable

This manuscript details an ODS design where individual observations are sampled with probabilities determined by an inexpensive, time-varying auxiliary variable that is related but is not equal to the response, and proposes a semi-parametric, sequential offsetted logistic regressions (SOLR) approach.

Selection Bias and Information Bias in Clinical Research

Two categories of bias are focused on: selection bias and information bias which may affect the internal validity of a clinical study.

The emerging landscape of health research based on biobanks linked to electronic health records: Existing resources, statistical challenges, and potential opportunities

The current landscape of availableBiobanks is characterized and specific biobanks are described, including their place of origin, size, and data types, to discuss statistical issues related to biobank research such as study design, sampling strategy, phenotype identification, and missing data.

Semiparametric regression estimation in the presence of dependent censoring

SUMMARY We propose a semiparametric estimation procedure for estimating the regression of an outcome Y, measured at the end of a fixed follow-up period, on baseline explanatory variables X, measured

Challenges and Opportunities for Using Big Health Care Data to Advance Medical Science and Public Health.

Opportunities for training and for bolstering collaboration among subject matter experts, methodologists, practicing clinicians, and health system leaders are identified to help ensure that methods problems are identified and resulting advances are translated into mainstream research practice more quickly.

Potential need for expanded pharmacologic treatment and lifestyle modification services under the 2017 ACC/AHA Hypertension Guideline

The authors use 2011‐2014 NHANES data to describe the population groups most affected by the new guideline, compared with the previous JNC‐7 guideline, and describe the previous interaction with the health care sector among those adults recommended new or intensified pharmacologic treatment and/or lifestyle modification.

Blood pressure and ageing

All evidence indicates that treating the elderly hypertensive patient will reduce the risk of cardiovascular events, however, there is no evidence yet for the very elderly.
