Wearable Monitors Increase Health Care Use in AF Patients

New Insights: Wearable Monitoring Devices May Increase Health Care Usage in AF Patients

Recent research in the Journal of the American Heart Association has revealed that the use of wearable cardiac monitors among individuals with atrial fibrillation (AF) might lead to a higher consumption of health care services versus AF patients who do not use these technological aids. The study also identified that a subset of individuals utilizing these wearables may suffer from anxiety linked to their heart condition and the ongoing self-monitoring.

Analyzing the Data and Core Discoveries

This investigation, carried out at an outpatient electrophysiology facility from December 2022 to February 2023, analyzed the health-related behaviors of 172 AF patients with an average age of 73, of which 42% were female. The team, under the guidance of Lindsey Rosman, PhD, from the University of North Carolina School of Medicine, assessed patient survey responses and scrutinized electronic health records over the course of nine months. Of the 172, 83 individuals who regularly used devices like Apple Watches or Fitbits were pitted against a control group of 87 patients, with careful matching based on socioeconomic background and medical history.

Those employing wearable technology were more vigilant in tracking their AF symptoms and expressed greater levels of worry and preoccupation with their AF management. Dr. Rosman and her research team discovered that 20% of these patients were dealing with increased anxiety, especially after receiving notifications of abnormal heart rhythms from their devices.

The study’s critical findings illustrated that the category of patients using wearable technology sought more AF-specific medical services. This group showed an increased frequency of outpatient visits, diagnostic tests for heart rhythm, and procedures like ECGs, echocardiograms, and even AF ablation procedures compared to their counterparts without wearable technology. They tended to reach out more to health care providers through informal means of communication, such as telephone calls and online patient portals.

The researchers behind the study succinctly suggest that “AF patients employing wearable devices exhibit a substantial preoccupation with their cardiac symptoms, a tendency towards excessive symptom monitoring, and raise more issues concerning their treatment for AF as opposed to those who don’t use these monitoring tools.” They also highlighted the irony in how wearable technologies, designed for patient reassurance and safety, can conversely lead to anxiety and added pressure on health services.

Expert Commentary and the Horizon

In an associated editorial, Christopher C. Cheung, MD, MPH, and Mussa Saad, MD, recognize that the findings are thought-provoking, signifying a possible increase in health care activity resulting from the adoption of wearable technologies. Nonetheless, they raised concerns over potential biases due to the study’s retrospective model. They called attention to the importance of educating patients about these devices and how to accurately interpret the data, particularly concerning false alarms.

In terms of potential conflicts of interest, Dr. Rosman noted that she has received funding and consultancies from multiple entities, as detailed in her study disclosures, whereas Drs. Cheung and Saad reported no financial ties of concern.

Researchers at The Ohio State University have recently introduced a forward-thinking artificial intelligence system on May 1, 2024. This AI tool holds the potential to forecast optimum stroke prevention treatments for individuals dealing with cardiac conditions. The innovative system works by digitally emulating the effects of clinical trials, thus assessing the effectiveness of medications without the need for physical trials.

Innovative Strides in Prescriptive Analytics

This sophisticated prediction model harnesses a massive dataset of anonymized patient information, accumulated from the records shared by employers, healthcare providers, and insurance companies. Multiple patient histories form a foundational base, enabling an initial round of training using a technique akin to foundation models used in generative platforms akin to ChatGPT.

Ping Zhang, an academic with dual appointments in computer science and engineering and biomedical informatics at Ohio State, praised the model’s innovation. According to Zhang, “This algorithm outstrips any existing models. It not only uplifts performance by 7% to 8% compared with other algorithms but also generates results that mirror those from actual randomized clinical trials.”

Published under the moniker CURE, for “CaUsal tReatment Effect estimation,” this AI framework was thoughtfully developed as a patient “digital twin,” which customizes treatment recommendations based on unique patient traits. The system is surprisingly versatile, applicable across diverse medical conditions and pharmaceuticals.

The model’s precision was fine-tuned through integrating patient specifics with comprehensive biomedical knowledge graphs.

AI’s Revolutionary Role in Enhancing Medical Imaging Precision

The Integration of AI in Medical Imaging: Enhancing or Assisting Diagnostic Precision?

The convergence of Artificial Intelligence (AI) in the healthcare sector, particularly within the realm of medical imaging, has sparked considerable debate. With AI algorithms progressively showing their capability to bolster the precision and efficiency in recognizing ailments from medical images, the medical fraternity is actively engaging in discussions on how AI’s integration may transform their practice.

AI’s Emergent Function in Medical Imaging

At the forefront of embracing AI advancements is Dr. Ronald Summers, a prominent radiologist and AI researcher with the National Institutes of Health. Dr. Summers ardently advocates for the utilization of AI in current practice, asserting, “Some AI methods are so advanced that their use should be instituted without delay. We’re neglecting valuable insights by not leveraging these techniques immediately.” His laboratory has birthed software capable of discerning a variety of conditions from medical images, but these innovations remain on the fringe of widespread clinical use, a phenomenon he attributes to factors including the conservative culture within medicine.

Traditional roles of radiologists include using computers for image enhancement and identifying areas warranting careful examination. AI’s evolving technology can interpret images with increasing sophistication, suggesting possible diagnoses and even drafting medical reports — tasks traditionally reserved for human intellect. Out of the 700 AI innovations that have received FDA clearance, 75% are geared towards radiology, yet a mere 2% of radiology practices have integrated these AI tools.

Concrete evidence showcases AI’s capabilities, as seen with the reduction in overlooked instances of breast cancer and achieving greater procedural efficiencies. However, reservations persist. Dr. Curtis Langlotz of Stanford University, director of an AI in medicine hub, articulates the field’s caution, pinpointing uncertainties related to AI’s testing and operational parameters: “Without clarity regarding the patient cases on which AI was evaluated, or if such cases mirror the ones observed in our practice, it creates a cloud of doubt as to whether AI would be efficacious for our patients.”

As AI continues to expand its presence, the FDA engages in deliberations to approve fully independent AI systems. Meanwhile, Europe has already greenlighted Oxipit, an AI that independently reviews and annotates chest X-rays. Nonetheless, in the US, it’s anticipated that AI will initially complement radiologists in a manner akin to the aviation industry’s autopilot.

Dr. Laurie Margolies from Mount Sinai Hospital sees merit in a synergistic approach, remarking, “Patients gain more assurance when I tell them that both I and the computer have reviewed their scans and we are in agreement.”

Research further validates this synergistic effect; for example, in Sweden, an AI-supported radiologist identified 20% more cancer cases compared to a team of two radiologists who did not utilize AI technology, while simultaneously mitigating workloads by 44%. Regardless of the apparent gains, the criticality of human oversight remains paramount. Dr. Kristina Lang from Lund University accentuates the importance of radiologists delivering the final verdict to maintain patients’ confidence.

Experts such as Dr. Saurabh Jha from the University of Pennsylvania contend that extremely precise and dependable AI systems are essential for radiologists to consider minimizing their active participation in diagnostics. Until such tools reach this level of reliability, the majority of radiology professionals are likely to approach AI outputs with caution.

As the interface of AI in radiology continues to mature, it aims to augment rather than usurp the acumen of medical professionals. The journey of AI in this field is one of prudent optimism, as it evolves to provide formidable support and potentially amplify the capabilities of radiologists.
