New in JMIR Cancer: DermaDashboard: Bridging the Gap Between FHIR Standards and Clinical Usability
DermaDashboard: Bridging the Gap Between FHIR Standards and Clinical Usability
Objective: The complexity of the Fast Healthcare Interoperability Resources (FHIR) standard limits its direct usability for clinicians despite its transformative potential in healthcare data management. To bridge this gap, we aimed to describe the development of an interactive dashboard enabling non-technical users to intuitively build and analyze #Oncologic #Patient cohorts. By leveraging FHIR, we aimed to enhance data accessibility and interoperability in clinical practice. Methods: DermaDashboard builds on a Structured Query Language (SQL) database using a relational FHIR model, which ensures data compliance with the FHIR schema. A materialized view was assembled and optimized performance by providing only relevant data. The user interface was built with Grafana and supports intuitive data exploration. We applied DermaDashboard to the use case of melanoma, demonstrating its utility in real-world #Oncologic cohort analyses. Results: DermaDashboard was successfully built and integrated into the clinical environment, identifying 3,949 melanoma #Patients and corresponding to 82,783 electronic health records. The primary FHIR resources used were #Patient, DiagnosticReport, and QuestionnaireResponse, and captured 54 data attributes, including demographics, histological classifications, genetic mutations, clinical and pathological staging, treatments, and procedures. Clinicians can filter the data using 29 variables to create specific subcohorts. The dashboard also enables operational insights by tracking annual trends in procedures and drug administrations. Conclusions: DermaDashboard enhances data accessibility for non-technical clinical users while showcasing the power of FHIR standardization in healthcare applications. By enabling #Oncological insights and identifying cohort discrepancies, it enhances both clinical decision-making and data quality.

Did you also check how quick HR measurements respond to changes in HR or just steady state measurements?
New in JMIR Cardio: Validity of #heart Rate Measurement Using Wearable Devices During #cardiopulmonary Exercise Testing in Patients With #cardiovascular Disease: Prospective Pilot Validation Study
Validity of #heart Rate Measurement Using Wearable Devices During #cardiopulmonary Exercise Testing in Patients With #cardiovascular Disease: Prospective Pilot Validation Study
Background: Wearable devices offer a promising solution for remotely monitoring #heart rate (HR) during home-based cardiac rehabilitation. However, evidence regarding their accuracy across varying exercise intensities and patient profiles remains limited, particularly in populations with #cardiovascular disease (CVD), such as those with #heart failure (HF). Objective: The objective of our study was to evaluate the accuracy of HR measurements obtained using the Fitbit Inspire 3 during #cardiopulmonary exercise testing (CPX) in patients with CVD, including those with HF. Methods: In this single-center, prospective pilot study, 30 patients with CVD undergoing CPX were enrolled. HR was simultaneously recorded using electro#cardiography (ECG) and the Fitbit Inspire 3 at 1-min intervals across various CPX phases: rest, exercise below and above the anaerobic threshold (AT), and recovery. The correlation between the two methods was assessed using Pearson’s correlation coefficient. Measurement error was quantified by mean absolute error and mean absolute percentage error (MAPE), with a MAPE ≤10% defined as the threshold for acceptable agreement. Results: All data points were 630 points per min. The Fitbit Inspire 3 demonstrated a strong overall correlation with ECG-derived HR (r = 0.90; interquartile range: 0.88–0.91) and an acceptable MAPE of 5.40±8.33%. The total error was 94/630 (15%), with overestimation and underestimation of 37/630points (6%) and 57/630points (9%), respectively. The rate of HR underestimation reached 19/119points (16%) during exercise above AT, compared to 1/30point (3%) at rest. When stratified by HF stage (B vs. C), underestimation was more pronounced in patients with HF (14/275points; 5% vs.40/355points; 11%). Conclusions: The Fitbit Inspire 3 provides acceptable validity for HR monitoring during CPX in patients with CVD. However, clinicians should interpret HR data with caution during high-intensity exercise, especially in patients with HF.

New JMIR MedInform: An artificial intelligence (#AI)–Based Framework for Predicting Emergency Department Overcrowding: Development and Evaluation Study
An artificial intelligence (#AI)–Based Framework for Predicting Emergency Department Overcrowding: Development and Evaluation Study
Background: Emergency department (ED) overcrowding remains a critical challenge, leading to delays in #patient care and increased operational strain. Current hospital management strategies often rely on reactive decision-making, addressing congestion only after it occurs. However, effective #patient flow management requires early identification of overcrowding risks to allow timely interventions. Machine learning (ML)–based predictive modeling offers a solution by forecasting key #patient flow measures, such as waiting count, enabling proactive resource allocation and improved hospital efficiency. Objective: The aim of this study is to develop ML models that predict ED waiting room occupancy (waiting count) at 2 temporal resolutions. The first approach is the hourly prediction model, which estimates the waiting count exactly 6 hours ahead at each prediction time (eg, a 1 PM prediction forecasts 7 PM). The second approach is the daily prediction model, which forecasts the average waiting count for the next 24-hour period (eg, a 5 PM prediction estimates the following day’s average). These predictive tools support resource allocation and help mitigate overcrowding by enabling proactive interventions before congestion occurs. Methods: Data from a partner hospital’s ED in the southeastern United States were used, integrating internal and external sources. Eleven different ML algorithms, ranging from traditional approaches to deep learning architectures, were systematically trained and evaluated on both hourly and daily predictions to determine the models that achieved the lowest prediction error. Experiments optimized feature combinations, and the best models were tested under high #patient volume and across different hours to assess temporal accuracy. Results: The best hourly prediction performance was achieved by time series vision transformer plus (TSiTPlus) with a mean absolute error (MAE) of 4.19 and a mean squared error (MSE) of 29.36. The overall hourly waiting count had a mean of 18.11 and a SD (σ) of 9.77. Prediction accuracy varied by time of day, with the lowest MAE at 11 PM (2.45) and the highest at 8 PM (5.45). Extreme case analysis at (mean + 1σ), (mean + 2σ), and (mean + 3σ) resulted in MAEs of 6.16, 10.16, and 15.59, respectively. For daily predictions, an explainable convolutional neural network plus (XCMPlus) achieved the best results with an MAE of 2.00 and a MSE of 6.64. The daily waiting count had a mean of 18.11 and a SD of 4.51. Both models outperformed traditional forecasting approaches across multiple evaluation metrics. Conclusions: The proposed prediction models effectively forecast ED waiting count at both hourly and daily intervals. The results demonstrate the value of integrating diverse data sources and applying advanced modeling techniques to support proactive resource allocation decisions. The implementation of these forecasting tools within hospital management systems has the potential to improve #patient flow and reduce overcrowding in emergency care settings. The code is available in our GitHub repository. Trial Registration:

Evaluating a Customized Version of ChatGPT for Systematic Review Data Extraction in Health Research: Development and #usability Study
Background: Systematic reviews are essential for synthesising research in health sciences, yet they are resource-intensive and prone to human error. The data extraction phase, where key details of studies are identified and recorded in a systematic manner, may benefit from the application of automation processes. Recent advancements in artificial intelligence (#AI) (AI), specifically Large Language Models (LLMs) like ChatGPT, may streamline this process. Objective: This study aims to develop and evaluate a custom Generative Pre-Training Transformer (GPT), named Systematic Review Extractor Pro, for automating the data extraction phase of systematic reviews in health research Methods: OpenAI's GPT Builder was used to create a GPT tailored to extract information from academic manuscripts. The Role, Instruction, Steps, End goal, and Narrowing (RISEN) framework was used to inform prompt engineering for the GPT. A sample of 20 studies across two distinct systematic reviews was used to evaluate the GPT's performance in extraction. Agreement rates between the GPT outputs and human reviewers were calculated for each study subsection. Results: Mean time for human extraction was 36 minutes per study, compared to 26.6 seconds for the GPT plus 13 minutes of human review. The GPT demonstrated high overall agreement rates with human reviewers, achieving 91.45% for review 1 and 89.31% for review 2. It was particularly accurate in extracting study (review 1: 95.25; review 2: 90.83%) and participant (review 1: 95.03%; review 2: 90.00%) characteristics, with lower performance observed in more complex areas such as methodological characteristics (87.07%) and statistical results (77.50%). The GPT correct when the human reviewer was incorrect in 14 instances (3.25%) in review 1 and four instances (1.16% in review 2). Conclusions: The custom GPT significantly reduced extraction time and shows evidence that it can extract data with high accuracy, particularly participant and study characteristics. It was most effective in extracting information such as study and participant characteristics. This tool may offer a viable option for researchers seeking to reduce resource demands during the extraction phase, though more research is needed to evaluate test-retest reliability, performance across broader review types, and accuracy extracting statistical data. The tool in the current study has been made open access.
