Telehealth and Its Impact on Low-Value Care 

Telehealth has transformed outpatient care, offering unprecedented convenience and accessibility. While it has clear benefits, concerns remain about whether telehealth could contribute to low-value care—medical services that provide minimal clinical benefit, pose potential harm, or increase costs unnecessarily. This analysis explores how telehealth intersects with the delivery of low-value care, focusing on office-based services, laboratory testing, imaging, and mixed-modality services. The foundation for this discussion is a recent comprehensive study published in JAMA, which provides significant insights for providers. 

The Growth of Telehealth 

The COVID-19 pandemic catalyzed the rapid expansion of telehealth, shifting it from a supplementary service to a primary component of healthcare delivery. Initially adopted to minimize exposure risk, telehealth quickly proved its efficacy in maintaining continuity of care. Today, its advantages—convenience, reduced travel time, and the ability to reach remote patients—have solidified its role in modern medical practice. 

However, the ongoing integration of telehealth has prompted scrutiny regarding its impact on care quality and potential associations with low-value care. Low-value care refers to services that yield minimal or no clinical benefit, potentially exposing patients to unnecessary risks and contributing to escalating healthcare costs. Could the proliferation of telehealth inadvertently increase these types of services? 

The JAMA Study: Analyzing Telehealth’s Influence on Low-Value Care 

A pivotal study published in JAMA set out to answer this question by analyzing Medicare claims data from 2019 to 2022. This large-scale research aimed to identify trends in service delivery across practices with varying levels of telehealth use. The study divided practices into three tertiles: high, moderate, and low telehealth usage, based on the number of telehealth claims per 1,000 beneficiaries. 

The researchers categorized low-value care into four primary types: 

Office-based services: Routine in-person procedures, such as annual wellness visits or physical exams, that might be unnecessary. 

Laboratory-based services: Tests conducted without a clear clinical indication, often contributing to diagnostic overuse. 

Imaging services: Diagnostic imaging ordered outside of evidence-based guidelines. 

Mixed-modality services: Comprehensive services that span multiple formats, such as a combination of lab tests and imaging. 

By comparing these categories across practices with different levels of telehealth adoption, the study sought to understand how telehealth influenced the prevalence of low-value services. 

The Impact of Telehealth on Service Patterns 

The JAMA study yielded several compelling findings that shed light on the relationship between telehealth and low-value care: 

1. Reduction in Office-Based Low-Value ServicesPractices with high levels of telehealth usage demonstrated a notable decrease in low-value office-based services. This trend suggests that certain unnecessary in-person screenings, exams, or consultations were less frequently conducted, as telehealth often shifts the focus toward patient-reported symptoms and virtual evaluations. Providers leveraged telehealth to streamline patient interactions and prioritize urgent or essential services. 

This decline could indicate that telehealth encourages more targeted and efficient care, where patients are only brought in for physical visits when necessary. However, the shift also implies that some comprehensive assessments may be sacrificed, which could have mixed implications depending on the context. 

2. Increase in Imaging-Based Low-Value ServicesConversely, the study found that practices with significant telehealth adoption showed a slight uptick in imaging services deemed low-value. One potential explanation is that telehealth’s limitations, such as the inability to conduct a thorough physical examination, prompt providers to rely on imaging as a diagnostic substitute. Without the tactile and observational components of an in-person visit, clinicians may order imaging to compensate for diagnostic uncertainty. 

This finding underscores the importance of developing telehealth protocols that guide providers in determining when imaging is necessary. Training on virtual diagnostic acumen and clear guidelines can help mitigate this trend. 

3. Mixed Impact on Laboratory ServicesThe impact on laboratory-based low-value care was less uniform. Some practices reported a decline in unnecessary lab tests, while others experienced unchanged or even increased rates. This variation points to differing telehealth strategies and patient demographics across practices. For example, providers serving populations with chronic conditions might use telehealth to monitor ongoing treatment plans, which could involve repeated lab work. Meanwhile, practices focusing on episodic or acute care may see less frequent lab testing. 

Overall, the findings reflect that telehealth can alter the dynamics of low-value service delivery, for better or worse, based on how it is implemented. 

Policy and Practice Implications 

The results of the JAMA study provide crucial lessons for providers, policymakers, and healthcare administrators. While telehealth offers clear benefits in terms of patient reach and efficiency, its potential drawbacks require careful consideration. To maximize telehealth’s positive impact while minimizing low-value care, stakeholders should focus on several key areas: 

1. Implementing Comprehensive Provider TrainingProviders need tailored training on telehealth best practices, emphasizing decision-making criteria that help prevent overreliance on imaging and lab testing. This training should include strategies for effective virtual patient assessments and recognizing when an in-person follow-up is warranted. 

2. Establishing Telehealth-Specific GuidelinesClear, evidence-based guidelines can aid providers in distinguishing between situations where telehealth is appropriate and those that necessitate in-person evaluations. These guidelines should also outline the appropriate use of imaging and laboratory tests in telehealth settings to avoid unnecessary utilization. 

3. Enhancing Quality Assurance MeasuresHealthcare systems should implement quality assurance programs that monitor telehealth encounters for patterns of low-value care. These programs could include peer reviews and feedback loops that enable continuous improvement. 

4. Educating Patients on Telehealth UsePatient education is vital to set realistic expectations for telehealth visits. Informing patients about the limitations and strengths of virtual care helps them understand when telehealth is suitable and when an in-person visit may be necessary. This understanding can prevent pressure on providers to order tests that might otherwise be considered low-value. 

The JAMA study highlights that while telehealth has a nuanced impact on low-value care, its role in healthcare is irreplaceable and expanding. Providers must balance telehealth’s convenience and accessibility with an ongoing commitment to evidence-based care. By refining telehealth practices, implementing robust training, and setting clear guidelines, the risk of increased low-value care can be effectively managed. 

Telehealth, when wielded thoughtfully, offers an opportunity to improve patient access and satisfaction without compromising care quality. As the landscape continues to evolve, providers should remain vigilant and adaptable, embracing telehealth’s potential while safeguarding against unintended consequences. With deliberate practice, telehealth can align with value-based care principles, ensuring that medical services are both efficient and clinically meaningful.
