Triaging Patients with Artificial Intelligence for Respiratory Symptoms in Primary Care to Improve Patient Outcomes
In the study by Ellertsson et al., 2023, the researchers aimed to develop a machine-learning model to triage patients with respiratory symptoms before their primary care clinic visits and evaluate patient outcomes based on the triage process. With respiratory symptoms being a common complaint in primary care, effective triaging can help manage physician workload and healthcare costs. The model was trained using clinical features available before the medical visit, using 1,500 patient records from primary care clinics in Reykjavík, Iceland. The patients were categorized into ten risk groups based on their scores from the model. The results showed that risk groups 1 to 5, consisting of younger patients with lower C-reactive protein values, had lower re-evaluation rates, antibiotic prescription rates, chest x-ray referrals, and no cases of pneumonia detected in CXRs or diagnosed by physicians. Therefore, the model successfully triaged patients following expected outcomes, highlighting its potential to reduce the number of unnecessary CXR referrals, consequently decreasing clinically insignificant findings without requiring clinician input.
In conclusion, this study demonstrated the effectiveness of a machine-learning model in triaging patients with respiratory symptoms before primary care visits. The model provided valuable insights into patient outcomes by accurately categorizing patients into different risk groups. Notably, the model’s ability to eliminate CXR referrals in lower-risk groups 1 to 5 helped decrease the occurrence of clinically insignificant findings and reduce the burden on clinicians. These findings highlight the potential of machine learning in optimizing triage processes and improving resource allocation in primary care settings, ultimately benefiting both patients and healthcare providers.(1)

Unveiling the Future: 3D Deep Learning Revolutionizes Lung Cancer Screening
Lung cancer is the leading cause of cancer-related deaths in the United States, with approximately 160,000 lives lost in 2018 alone. While low-dose computed tomography (LDCT) has shown promising results in reducing mortality rates, challenges such as inter-grader variability and high rates of false positives and false negatives persist. However, a breakthrough has arrived in the form of a deep learning algorithm designed to predict the risk of lung cancer using a patient’s current and prior CT volumes. This algorithm has achieved remarkable performance, boasting a state-of-the-art 94.4% area under the curve on a comprehensive dataset from the National Lung Cancer Screening Trial. The algorithm’s efficacy was further demonstrated in two reader studies, surpassing the performance of six radiologists in cases where prior CT imaging was unavailable.
These findings open the door to optimizing the screening process through computer assistance and automation, presenting an opportunity to enhance the accuracy, consistency, and global adoption of lung cancer screening. As a vast majority of patients still go unscreened, the potential of deep learning models to increase screening efficiency and effectiveness brings hope for the future of lung cancer detection and prevention worldwide.(2)

Decoding Lung Cancer: Unleashing Deep Learning to Unlock Insights from Histopathology Images
In pathology, visual inspection of histopathology slides has long been the gold standard for assessing lung tumor characteristics. However, distinguishing between adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC) requires the expertise of experienced pathologists. In a groundbreaking study, we trained a deep convolutional neural network, specifically the inception v3 model, on whole-slide images from The Cancer Genome Atlas. The results were astounding. Our AI model demonstrated exceptional accuracy in automatically classifying lung tissue into LUAD, LUSC, or normal lung tissue, with an average area under the curve (AUC) of 0.97 – on par with pathologists’ performance. We further validated our model using independent datasets comprising frozen tissues, formalin-fixed paraffin-embedded tissues, and biopsies. Taking innovation even further, the developed neural network was trained to predict the ten most frequently mutated genes in LUAD.
Remarkably, we found that six of these genes – STK11, EGFR, FAT1, SETBP1, KRAS, and TP53 – can be accurately predicted from pathology images, with AUC values ranging from 0.733 to 0.856 when assessed on a separate population. This breakthrough streamlines lung cancer classification and provides a novel approach to genetic predictions. With the potential to enhance precision medicine and guide targeted therapies, our AI-driven advancements marks hold immense promise in revolutionizing the field of lung cancer diagnosis and treatment.(3)
