Classifying Continuous Glucose Monitoring Documents From Electronic Health Records

Fletcher, J., Zheng, Y., Iturrate, E., Li, L., Wu, B., Small, W. R., Zweig, S., Fletcher, J., Chen, Z., & Johnson, S. B. (2025). (p. 19322968251324535).
Abstract
Abstract
Clinical use of continuous glucose monitoring (CGM) is increasing storage of CGM-related documents in electronic health records (EHR); however, the standardization of CGM storage is lacking. We aimed to evaluate the sensitivity and specificity of CGM Ambulatory Glucose Profile (AGP) classification criteria.

Concurrent Validity of a Physical Activity Vital Sign Used in an Adult Preventive Cardiology Clinic

Fletcher, J., McCarthy, M., Fletcher, J., Melkus, G., Vorderstrasse, A., Chehade, M., & Katz, S. (2025).
Abstract
Abstract
In clinical settings, counseling patients on physical activity starts by assessing patients' current physical activity levels. Self-report measures of PA are generally easy to administer; however, they may be too long to be convenient and are known to correlate poorly with objective measures of physical activity.

Heterogeneous depressive symptom trajectories among women with type 2 diabetes: findings from the Women's Interagency HIV Study

Fletcher, J., Perez, N. B. B., D’Eramo Melkus, G., Fletcher, J., Allen-Watts, K., Jones, D. L., Collins, L. F., Ramirez, C., Long, A., Cohen, M. H., Merenstein, D., Wilson, T. E., Sharma, A., & Aouizerat, B. (2025). (Vols. 59, Issue 1).
Abstract
Abstract
Depression affects 33% of women with type 2 diabetes (T2D) and leads to increased risks of premature mortality. Fluctuation and variation of depressive presentations can hinder clinical identification.

Fletcher, J., Dunn Navarra, A.-M. M., Gormley, M., Liang, E., Loughran, C., Vorderstrasse, A., Garcia, D. R., Rosenberg, M. G., Fletcher, J., & Goldsamt, L. A. (2024). (Vols. 4, p. 100263).
Abstract
Abstract
Describe the development and testing of a web-based platform for antiretroviral treatment (ART) adherence support among HIV+ adolescents and young adults (AYA) in a randomized controlled trial (RCT).

Factors Associated With the Cardiovascular Health of Black and Latino Adults With Type 2 Diabetes

Fletcher, J., McCarthy, M. M., Fletcher, J., Wright, F., Del Giudice, I., Wong, A., Aouizerat, B. E., Vaughan Dickson, V., & Melkus, G. D. D. (2024). (Vols. 26, Issues 3, pp. 438-448).
Abstract
Abstract
The purpose of this study was to assess the levels of cardiovascular health (CVH) of Black and Latino adults with type 2 diabetes (T2D) and examine the association of individual and microsystem level factors with their CVH score.

A Pilot Study Toward Development of the Digital Literacy, Usability, and Acceptability of Technology Instrument for Healthcare

Fletcher, J., Groom, L. L., Feldthouse, D., Robertiello, G., Fletcher, J., & Squires, A. (2024). (Vols. 42, Issues 12, pp. 879-888).
Abstract
Abstract
Electronic health record proficiency is critical for health professionals to deliver and document patient care. There is scarce research on this topic within undergraduate nursing student populations. The purpose of this study is to describe the psychometric evaluation of the Digital Literacy, Usability, and Acceptability of Technology Instrument for Healthcare. A cross-sectional pilot study for psychometric evaluation of the instrument was conducted using data collected through an emailed survey. Exploratory factor analysis, inter-item and adjusted item-total correlations, and Cronbach's α calculated subscale reliability. A total of 297 nursing students completed the survey. A seven-factor structure best fit the data: technology use-engagement, technology use-confidence, technology use-history, electronic health record-ease of use, electronic health record-comparability, and electronic health record-burden. Cronbach's α indicated good to very good internal consistency ( α = .68 to .89). The instrument effectively measured digital literacy, acceptance, and usability of an electronic health record and may be implemented with good to very good reliability across varied healthcare simulation and training experiences.

Sleep Quality Mediates the Relationship Between Sleep Hygiene and Psychological Stress Among Adults With Multiple Cardiovascular Risk Factors

Fletcher, J., Liu, X., Li, J., Hu, J., Fletcher, J., Commodore-Mensah, Y., & Himmelfarb, C. R. (2024).
Abstract
Abstract
Poor sleep quality and psychological stress are interrelated and disproportionately affect adults with multiple cardiovascular disease (CVD) risk factors. Maintaining an optimal home environment and engaging in healthy bedtime behaviors are important components of sleep hygiene practices that influence sleep health and mental well-being. However, research is scarce in exploring the associations between sleep hygiene, sleep quality, and psychological stress among adults with multiple CVD risk factors.

Association Between Types of Family Support and Glycemic Control for Adults With Cognitive Impairment

Fletcher, J., Zheng, Y., Lawrence, K., Fletcher, J., Qi, X., & Wu, B. (2023). (Vols. 9, p. 23337214231218800).
Abstract
Abstract
Family support is important in assisting with diabetes self-management for individuals with cognitive impairment, but what types of family support are most effective remain unknown.
