Racial and Ethnic Differences in the Use of Electronic Medical Record Messaging Among Patients With Breast Cancer: A Quality Improvement Study.

INTRODUCTION: Despite evidence that use of electronic medical record (EMR) messaging positively impacts patients with cancer, there is little research on utilization patterns. The objective of this study is to describe the use of EMR messaging among breast cancer patients so that future interventions may be developed and targeted appropriately. MATERIALS AND METHODS: Sociodemographic and MyChart usage data were collected. Study eligibility included patients who completed a visit at an academic breast center and sent at least one message to a provider during the study period (May 2021-May 2022). Chi-square and t-tests were used to describe differences between users and nonusers of EMR messaging. ANOVA and chi-square were used to describe differences between race/ethnicity. RESULTS: A total of 4069 patients with activated MyChart accounts were included in the analysis. About 3575 (87.9%) were messaging users and 494 (12.1%) were nonusers. The mean age of users was significantly lower compared to the nonusers (57.7 vs 61.2, P< .001). Compared to non-Hispanic White (NHW) individuals, non-Hispanic Black (NHB) (odds ratio [OR]: 0.38, CI [0.21, 0.37]) and Hispanic individuals (OR: 0.35, CI [0.22, 0.57]) were significantly less likely to use electronic messaging. There were statistically significant racial/ethnic differences in the types of messages sent among EMR users. CONCLUSION: Our study shows disparate EMR messaging utilization based on age, race, and primary language. As the availability of patient portals and electronic messaging increase, it is important to understand the barriers that patients face so that they can be addressed.

Electronic Medical Record-Based Electronic Messaging Among Patients with Breast Cancer: A Systematic Review.

BACKGROUND: Electronic medical record (EMR) systems and electronic messages are an increasingly common conduit between physicians and patients. Clear benefits of this type of communication have been established, especially among cancer patients. Studies suggest that patient portals and electronic messaging platforms can help with care coordination between oncology providers and facilitate asynchronous patient-provider communication. Despite the many benefits, there is little research regarding EMR and secure messaging use, particularly among patients with breast cancer. OBJECTIVES: The objective of this systematic review was to examine the evidence supporting the use of EMR-based messaging systems in patients with breast cancer. METHODS: A systematic literature search of Ovid MEDLINE, PubMed, Scopus, Web of Science CINAHL, and Cochrane Library was conducted. Studies were required to be published between 2005 and 2022 and report data on demographic information and electronic messaging between patients and providers. Studies were excluded if they reported insufficient data, did not include breast cancer patients, or were not published in English. RESULTS: This study identified 10 articles that met inclusion criteria. The resulting studies investigated topics such as: patterns of messaging and medication adherence, cancer screening, messaging as a predictor of behavior or outcomes, and symptom management. The literature indicates that electronic messaging with providers was associated with clinical benefits for breast cancer patients and improved screening behaviors. CONCLUSION: This review uncovered multiple areas to focus future research on, including ideal volume of electronic messages sent and their relation to prescription adherence, studies focusing solely on the breast cancer population, racial disparities in electronic messaging, and provider perceptions of electronic messaging. It is vital that more work be done to understand barriers and gaps in EMR usage to ensure that all individuals can access this increasingly essential medical service while minimizing physician workload and burnout.
