Early cognitive impairment detected by Linus Health’s Digital Clock and Recall Test https://www.digitalhealthglobal.com/early-cognitive-impairment-detected-by-linus-healths-digital-clock-and-recall-test/ Thu, 15 Feb 2024 15:15:23 +0000 https://www.digitalhealthglobal.com/?p=12705 In a recent peer-reviewed study published in the Alzheimer’s Research & Therapy journal, Linus Health, a digital health company focused on detecting early signs of Alzheimer’s and other dementias, demonstrated that their proprietary cognitive assessment, the Digital Clock and Recall (DCR™), outperforms commonly used paper-based tests in detecting early cognitive impairment and dementia. This groundbreaking research highlights the superior sensitivity, accuracy, and reduced ethnic and racial bias of Linus Health’s digital assessment, offering new hope for early intervention and improved care for individuals at risk of cognitive decline.

Superiority of the DCR Assessment

The study, titled “Digital Clock and Recall is Superior to the Mini-Mental State Examination (MMSE) for the detection of mild cognitive impairment and mild dementia,” adds to the growing body of evidence supporting the effectiveness of Linus Health’s DCR assessment. Over 20 other studies published in peer-reviewed scientific journals have also validated the DCR assessment within the Core Cognitive Evaluation (CCE™) solution. This latest research confirms that the DCR assessment surpasses the widely-used Mini-Mental State Examination (MMSE) in detecting early signs of cognitive impairment with greater accuracy and less biased outcomes.

Advantages and Applications of the DCR

The DCR assessment, a quick and accurate test, allows medical professionals to assess a patient’s cognitive functioning across various domains. It provides essential data that is used by Linus Health’s machine-learning algorithm to determine a patient’s level of cognitive functioning and predict their future risk of developing dementia. By facilitating early screenings with immediate results, the DCR assessment enables proactive interventions and personalized care for patients.

Addressing the Need for Early Detection

According to the Alzheimer’s Association, more than 80% of Americans are unfamiliar with mild cognitive impairment, which can be an early stage of Alzheimer’s disease. The symptoms of cognitive impairment are often not noticeable, leading to delayed screenings and an increased risk to patients’ brain health. The DCR assessment aims to bridge this gap by offering a quick, accessible, and comprehensive tool that helps healthcare providers identify cognitive impairment at its early stages, providing opportunities for timely interventions and improved patient outcomes.

Study Design and Results

The study involved a clinical research team from Linus Health who compared the cognitive classifications of the DCR assessment with the MMSE test, which is commonly performed using pen and paper. The research included a population of 706 participants, with an average age of 71 years, including 59% women and 85% white individuals. Participants underwent various neuropsychological tests and were evaluated by clinicians. Results showed that the DCR assessment had superior sensitivity and accuracy compared to the MMSE in detecting and classifying cognitive impairment. The DCR assessment successfully detected cognitive impairment in over 80% of the patients who were misclassified by the MMSE, providing valuable insights into the potential of digital assessments for more accurate and equitable healthcare.

Unlike the MMSE, the DCR assessment is not influenced by ethnicity, thereby addressing the issue of health disparities among ethnic minorities at higher risk of dementia. Additionally, the DCR assessment can be administered in multiple languages, ensuring increased accessibility for a diverse patient population. By analyzing over 500 metrics captured during the three-minute test, the DCR assessment can detect subtle signals related to various cognitive domains.

Linus Health’s Digital Clock and Recall (DCR) assessment has emerged as a superior alternative to traditional paper-based tests for early detection of cognitive impairment and dementia. With its enhanced sensitivity, accuracy, and reduced ethnic bias, the DCR assessment offers the potential to revolutionize the screening and management of cognitive health. By facilitating early intervention and personalized care, this digital assessment opens doors to a future where individuals can receive timely and proactive support to maintain optimal brain health.

Examining Perceptions and Concerns: Machine Learning-based Risk Prediction Models in Healthcare https://www.digitalhealthglobal.com/examining-perceptions-and-concerns-machine-learning-based-risk-prediction-models-in-healthcare/ Wed, 14 Feb 2024 11:12:19 +0000 https://www.digitalhealthglobal.com/?p=12684 In the recent systematic review published in The Lancet Digital Health, researchers delved into the perceptions and concerns surrounding machine learning (ML)-based risk prediction models in healthcare. The study aimed to analyze healthcare professionals’ and patients’ perceptions of these models and identify any gaps in knowledge or discrepancies in views between the two groups.

Upon thorough examination of 41 articles, the review discovered that overall perceptions of ML-based risk prediction models were positive. However, the findings also revealed areas of concern and reservations among healthcare professionals and patients.

One of the main gaps in knowledge identified in the study was the need for further research to determine optimal methods for model explanation and alerts. Ensuring transparency and explainability of ML models is crucial to gaining trust and acceptance from both healthcare professionals and patients. Developing robust techniques for explaining model predictions can help alleviate concerns and increase the adoption of ML-based risk prediction models in healthcare.

Additionally, the review highlighted the importance of understanding patients’ perceptions of ML-based predictive models as they play a crucial role in accepting and utilizing these models in their healthcare decisions. Therefore, it is essential to also consider their perspectives, preferences, and understanding of the technology to ensure effective communication and successful implementation.

The study pointed out that as the field of personalized medicine continues to advance, there is an increasing demand for complex risk prediction tools. ML methods, such as polygenic risk scores, are being explored to provide more accurate assessments of individual risk profiles. However, the current use of these tools is limited within healthcare settings, further emphasizing the need for research and validation to pave the way for wider adoption.

In summary, while ML-based risk prediction models show promise in healthcare, the systematic review revealed the importance of addressing concerns and reservations among healthcare professionals and patients. By bridging knowledge gaps, developing transparent explanations, and understanding patient perceptions, the field can work towards maximizing the potential benefits of ML in risk prediction and personalized medicine. Further research and collaboration between researchers, healthcare professionals, and patients are key to achieving this goal.

Machine Learning unveils Heart Failure subtypes and outcome predictions in landmark study https://www.digitalhealthglobal.com/machine-learning-unveils-heart-failure-subtypes-and-outcome-predictions-in-landmark-study/ Mon, 26 Jun 2023 09:42:13 +0000 https://www.digitalhealthglobal.com/?p=10223 In a comment published in The Lancet Digital Health, researchers have utilized machine learning techniques to identify distinct subtypes of heart failure and predict patient outcomes. Heart failure, a complex clinical syndrome associated with significant healthcare burdens and reduced quality of life, has traditionally been classified based on its various causes. However, this innovative research demonstrated the potential of machine learning to uncover previously unrecognized subtypes, improve risk prediction, and pave the way for personalized medicine.

Led by Amitava Banerjee and colleagues, the study analyzed extensive electronic health record data from a cohort of 313,062 patients sourced from The Health Improvement Network and Clinical Practice Research Datalink databases. To enhance the robustness of their findings, the researchers cross-referenced the data with the Hospital Episode Statistics, the UK death registry, and the UK Biobank. By employing unsupervised and supervised machine learning methods, the team successfully identified five distinct clusters of heart failure patients: early onset, late onset, atrial fibrillation-related, metabolic, and cardiometabolic.

Furthermore, the researchers delved into the underlying biological mechanisms associated with each heart failure subtype by examining polygenic risk scores and single-nucleotide polymorphisms (SNPs). The analysis revealed a specific SNP linked to the atrial fibrillation-related subtype, while polygenic risk scores for hypertension, myocardial infarction, and obesity were associated with the late-onset and cardiometabolic subtypes. Leveraging supervised machine learning, the team developed a prediction model, complete with an online risk calculator accessible to both patients and clinicians.

The study’s comprehensive approach and utilization of large-scale data warrant recognition. While previous research has employed machine learning to subtype heart failure patients, this study distinguishes itself by incorporating a significantly larger study population and reinforcing its findings through external validation. Additionally, the genetic validation sheds light on how big data associations can be correlated with underlying biological processes.

Although the study is a remarkable advancement, it does have certain limitations, which the authors acknowledge. One limitation is the lack of data on ejection fraction and imaging study results, which could have strengthened the results. The prediction model exhibited only moderate discriminatory ability regarding 1-year mortality and could benefit from focusing on individual heart failure subtypes to reduce data heterogeneity. Furthermore, more advanced artificial intelligence algorithms, such as convolutional neural networks and eXtreme gradient boosting, could enhance risk prediction.

The researchers’ findings hold promising implications for the future of heart failure treatment. By identifying novel subtypes, this research may facilitate the development of targeted therapies that can benefit patients. Additionally, further investigation into the potential of AI-powered pattern recognition techniques in echocardiography and cardiac MRI could advance the field, enabling the subtyping of heart failure, outcome prediction, and treatment response assessment.

As the prevalence of heart failure continues to rise, the integration of machine learning and big data analysis may offer new avenues for understanding and managing this complex condition. The ability to tailor treatment strategies to individual heart failure subtypes holds tremendous potential for improving patient outcomes and quality of life.

Closing Clinical and Research Gaps in Interstitial Lung Diseases: The Role of Machine Learning in Image Biomarker Research https://www.digitalhealthglobal.com/closing-clinical-and-research-gaps-in-interstitial-lung-diseases-the-role-of-machine-learning-in-image-biomarker-research/ Wed, 10 May 2023 09:50:57 +0000 https://www.digitalhealthglobal.com/?p=9825 Interstitial lung diseases (ILDs) are complex and challenging to manage, particularly when it comes to early detection, accurate prognosis, and effective response to therapy. Despite advances in high-resolution CT (HRCT), which is routinely used in ILD imaging, visual evaluation of the disease can still have high inter-reader variability and low sensitivity to changes in disease severity over short follow-up periods. In this article published in The Lancet Digital Health, authors discuss the clinical and research gaps in ILD diagnosis and prognosis and how machine learning can be applied to imaging biomarker research to close these gaps.

One of the key challenges in ILD management is early detection. Longitudinal studies have shown that incidentally detected subclinical interstitial lung abnormalities (ILAs) on HRCTs are associated with an increased risk of developing idiopathic pulmonary fibrosis (IPF). However, ILAs are also common and occur in up to 9% of lung cancer patients. Not all ILAs represent clinically meaningful diseases, making it challenging to reliably stratify them.

Accurate prognostication using baseline data is also essential in ILD management. Although diagnostic guidelines for several fibrotic lung diseases are available, ILD’s natural history is highly variable among individual patients. Some patients show progressive disease behavior despite conventional therapy, and waiting for patients to show a period of progression presents a major challenge in translating this concept to clinical care.

Effective monitoring of disease response to therapy through HRCT also proves to be a challenge. Visual evaluation of the disease can have high inter-reader variability and low sensitivity to changes in disease severity over short follow-up periods.

Addressing the challenges using machine learning algorithms

To address these challenges, machine learning algorithms can be implemented to identify ILD in at-risk populations, predict the extent of lung fibrosis, and correlate radiological abnormalities with lung function decline. Machine learning can also be used as an endpoint in treatment trials. Advances in image processing and analysis provide further opportunities to use machine learning that incorporates deep-learning-based image analysis and radiomics.

QTC and ML Methods

The authors discuss two methods for analyzing lung medical images: quantitative computed tomography (QCT) and Machine Learning (ML).

QCT uses algorithms to perform lung segmentation, image preprocessing, and image registration to measure variable attenuation corresponding to structural abnormalities.
On the other hand, ML performs feature extraction on digital images to produce numerical descriptors of texture, shape, and other distinctive characteristics that can be computationally analyzed to evaluate potential associations with clinical parameters. Machine Learning can be applied to image features extracted from CTs to evaluate diffuse lung disease and ILD.
The researchers further discuss the use of Deep Learning (DL) in feature-vector-based classification or regression, which can be linked together into composite feature vectors. The two methods are complementary and can provide meaningful prognostic signals, although their use is relatively unexplored and needs further research.

While ML and DL have the potential to identify imaging biomarkers not previously seen by the human eye, they can also lead to difficulties in interpreting abstract features internal to algorithms, which could result in these features and algorithms behaving like black boxes.
Validation is essential to ensure technical performance and clinical significance and minimize bias. Integration and application of ML and DL algorithms to clinical practice should also be studied.
The researchers suggest that ML and DL could play a crucial role in addressing diagnostic, prognostic, and therapeutic clinical research gaps in ILDs. Specifically, it could aid in the stratification of ILAs and established ILD and provide more sensitive tools to identify therapeutic responses in clinical trials.

Conclusions

Machine Learning can be a valuable tool in ILD management. By using ML algorithms to develop more precise and specific digital biomarkers, it can help address ILD diagnosis, prognostication, and therapy response challenges.
However, collaboration and consistency are required to develop optimal algorithms, and candidate radiological biomarkers should be validated against appropriate predictors of disease outcomes. Clinical and imaging data, as well as biological material such as bronchoalveolar lavage, cryobiopsy, or surgical lung biopsy, are essential in evaluating ILD.

Machine Learning models to predict neonatal seizures using Electronic Medical Record data https://www.digitalhealthglobal.com/machine-learning-models-to-predict-neonatal-seizures-using-electronic-medical-record-data/ Wed, 03 May 2023 09:40:59 +0000 https://www.digitalhealthglobal.com/?p=9687 Seizures are a significant risk factor for neonates with critical illnesses, and early detection and treatment are associated with improved outcomes. However, the gold standard for seizure detection, the continuous electroencephalogram (CEEG), is resource-intensive and not universally available. In The Lancet Digital Health, Jillian L McKee and colleagues report on a model to predict seizures in neonates, which can facilitate better resource allocation and early CEEG discontinuation where seizures are unlikely to occur.

Previous studies have shown that clinical features and initial laboratory values cannot predict which infants will develop seizures in the first days after birth. Models have attempted to predict neonatal seizures by combining clinical and early EEG data but with limited sensitivity and specificity. Additionally, these models rely primarily on retrospective, manual review of charts and EEGs to extract the key data to input into the model. This is time-consuming and might not be possible in clinical practice.

McKee and colleagues harnessed the power of their electronic medical record (EMR)-embedded EEG documentation system, which has reported more than 42,000 EEGs since 2018, including those from 1,117 neonates included in their study, 150 of whom had hypoxic ischaemic encephalopathy. The authors show that compliance with this documentation system has steadily increased since its introduction to more than 98%. This large trove of standardized EEG reports provides the basis for seizure-prediction model development.

The authors began with traditional logistic regression models, which showed seizure prediction accuracy of 84% (95% CI 78–89) in the overall cohort. However, machine learning algorithms outperformed logistic regression, achieving seizure prediction accuracy of up to 90% (95% CI 83–94), with recall (sensitivity) of up to 97% (91–100) in a random forest model. The model also performed well in the subset of neonates with hypoxic ischaemic encephalopathy, with an accuracy of 97% (88–99) and recall of 100% (100–100).

This model applies machine learning algorithms to widely available clinical data – in this case, CEEG reports. The authors show that machine learning algorithms might be well-suited to process the density of large EMR datasets. Recent studies have highlighted the potential for machine learning algorithms to detect seizures in real-time and predict seizures in infants with hypoxic ischaemic encephalopathy. McKee and colleagues expand this technology further, applying it not just to infants with hypoxic ischaemic encephalopathy or to direct analysis of digital EEG recordings. Instead, they apply it to broader groups of neonates at risk of seizures and use only summary CEEG reports from the EMR.

This work supports the promise of machine learning for neonatal seizure prediction, although much work must be done before clinical applications are possible. The authors’ institutional EMR-embedded EEG reporting system is valuable for their model but also has limitations. Because it is an institution-specific system, there are no comparable datasets from other centers to validate this model. Similarly, this limits clinicians’ ability to implement their model at other institutions without similar EMR-embedded EEG documentation systems. It is not known whether neonatal CEEG reports across other institutions have the same standardization and predictive ability as those of this single institution. In a gesture toward generalizability, the authors provide an online calculator for seizure prediction based on their model. This calculator allows clinicians to input a patient’s CEEG characteristics to view the classifier decision representing the estimated seizure risk. However, it is not shown whether this is valid for CEEG reports outside of their standardized institutional template.

Artificial Intelligence and Clinical Implementation https://www.digitalhealthglobal.com/artificial-intelligence-and-clinical-implementation/ Mon, 07 Mar 2022 15:46:00 +0000 https://www.digitalhealthglobal.com/?p=4851 What are the barriers to algorithm adoption among physicians and healthcare facilities and how can they be overcome?

We all know the progress and speed with which Artificial Intelligence (AI) is entering different sectors. Thanks especially to deep neural networks such as Machine Learning and Deep Learning, algorithms to support healthcare practice, i.e., public health, are being commercialised.

Despite many steps forward, only a few AI-based tools have actually been implemented in the various healthcare systems.

Lino Mari, Head of Technology at Healthware International, looked at the main reasons for this – transparency, data quality, and the ability of doctors and patients to rely on algorithms.

The quality of the data source and thus of the data itself is one of the main concerns of those in healthcare environments dealing with technology. Indeed, it is not always possible to establish the quality of the data and access to the algorithm source code.

In addition, there are still not enough published studies to directly support algorithms that have been tested in silico and may not reflect clinical practice.

How do you establish data quality? In the tech world it is often said: garbage in, garbage out.
