Study Reveals How to Improve Doctor Response Rates to Patient Portal Messages, Highlighting Disparities

Introduction

In the era of digital health, patient portals have become a primary channel for communication between patients and their healthcare providers. However, receiving a direct response from a physician, rather than a nurse or medical assistant, can be challenging. A recent study published in JAMA Network Open offers valuable insights into how patients can potentially improve their odds of getting a direct reply from their doctor, while also shedding light on systemic disparities in digital health communication.

Key Details

• Cordiality and Personalization Matter: Messages addressed to physicians by name, particularly using their last name (e.g., “Dear Dr. Tang”), significantly increased the likelihood of a response.
• Positive Tone is Key: A positive sentiment in the message, as opposed to neutral or negative tones, was associated with a higher probability of a doctor's direct engagement.
• Length Can Help: Longer messages, specifically those of 100 words or more, tended to receive more attention.
• Surprising Non-Factors: The study found that the number of exclamation marks or question marks, the inclusion of politeness markers like “please” and “thanks,” and the reading level of the message (ranging from third-grade to college level) had little to no impact on whether a doctor responded directly.
• Significant Disparities Identified: Historically marginalized groups experienced lower response rates. Black patients had a nearly 4-percentage point lower response rate than white patients. Patients whose primary language was not English, those with lower educational attainment, and those on Medicaid or Medicare/Medicaid also received fewer direct responses.
• Writing Style Explains Some Gaps: Analysis revealed that writing style accounted for substantial portions of these disparities: 48% of the difference between Black and white patients, 35% between Hispanic and white patients, nearly 61% between those with a high school diploma versus a college degree, and 43% between Medicaid patients and those with private insurance.

Background

Patient portals were designed to streamline healthcare interactions, offering a convenient way for patients to ask questions, request refills, and access medical information. However, the reality of portal message management often involves a complex triage system. As lead researcher Mitchell Tang, an assistant professor at Columbia University Mailman School of Public Health, explained, messages typically do not go directly to the doctor's inbox. Instead, they are first reviewed by nurses or medical assistants who assess urgency and complexity, deciding whether to escalate the message to the physician. This process, while necessary for managing high volumes, can inadvertently introduce biases and affect response times and the nature of the response.

“In many message triage systems, nurses and medical assistants must quickly assess messages and make judgments about their urgency, complexity and need for escalation,” Tang stated. “Given those constraints, writing style may understandably influence how messages are perceived and prioritized.”

The study analyzed over 3.6 million patient portal messages from more than 511,000 patients, employing computational methods to examine linguistic features such as formality, sentiment, and greeting patterns.

Impact Analysis

The findings suggest that conscious communication strategies can indeed influence physician engagement with patient portal messages. By adopting a more personalized and positive approach, patients may navigate the triage system more effectively, leading to more direct interactions with their doctors. This is particularly relevant given the increasing reliance on digital communication in healthcare. The study’s breakdown of how writing style contributes to disparities is particularly striking. It indicates that subtle differences in how messages are framed can have a tangible impact on equitable care delivery. The fact that writing style explains nearly 61% of the response gap between patients with a high school diploma and those with a college degree underscores the potential for digital communication tools to mirror or even exacerbate existing societal inequalities.

Broader Context

This research extends beyond the clinical setting, offering a broader commentary on the power of communication style in shaping perceptions and interactions. The principles highlighted—cordiality, personalization, and positive framing—are applicable to professional and personal communication across various domains. In a healthcare context, however, the implications are profound. They point to the need for both patient education on effective communication and for healthcare systems to critically examine their message triage protocols. The study implicitly questions whether these systems, while efficient, are inadvertently creating barriers for certain patient populations. The disparities observed align with broader patterns of health inequity, suggesting that digital health tools, if not carefully designed and implemented, could widen existing gaps in access and quality of care.

Future Outlook

The study’s authors suggest that these findings can inform the development of more equitable digital communication strategies within healthcare systems. This could involve training for both patients and healthcare staff, as well as refining algorithms used in automated message triage. Future research might explore the effectiveness of interventions aimed at mitigating these writing-style-related biases. Additionally, understanding the physician's perspective on portal message overload and the factors influencing their decision-making could provide a more comprehensive picture. As digital health continues to evolve, ensuring that these tools promote rather than hinder equitable patient-provider communication will be a critical challenge.

Conclusion

This study provides actionable advice for patients seeking more direct physician responses via patient portals and highlights critical issues of equity in digital healthcare communication. While simple adjustments in message composition—such as using a polite greeting with the doctor's name and maintaining a positive tone—can improve engagement, the research also reveals that systemic factors contribute to significant disparities in response rates. Healthcare providers and policymakers must consider these findings to foster more inclusive and effective digital communication practices, ensuring that technology enhances, rather than hinders, equitable patient care.
