Rheumatic Heart Disease IV: Nursing Management

AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...

Machine learning models accurately predict rheumatoid arthritis (RA) disease activity using longitudinal electronic health records. This enables personalized treatment strategies for better patient management.

Area of Science:

  • Rheumatology
  • Medical Informatics
  • Artificial Intelligence

Background:

  • Precision medicine increasingly utilizes machine learning (ML) for predicting therapeutic outcomes.
  • Initial clinical assessments are crucial for forecasting treatment success in chronic diseases.
  • Rheumatoid arthritis (RA) management can benefit from predictive models to optimize clinical decision-making.

Purpose of the Study:

  • To develop and validate ML models for predicting disease activity in RA patients.
  • To leverage longitudinal electronic health records (EHRs) for prognostic modeling.
  • To enhance personalized treatment selection and patient management in RA.

Main Methods:

  • A multicenter retrospective study analyzed EHRs from 1,864 RA patients across 5 Chinese tertiary hospitals (2017-2022).

Evaluation of Changes in Hydration and Body Cell Mass with Bioelectrical Impedance Analysis after Exercise Program for Rheumatoid Arthritis Patients

Published on: July 14, 2023

  • Longitudinal data (demographics, labs, medications) at baseline, 3, and 6 months were used.
  • Four ML models were trained to predict clinical remission (DAS28-ESR ≤ 2.6) at 6 months post-treatment.

    • Main Results:

    • The optimal internal validation model achieved 95.3% accuracy and 0.971 AUROC for predicting remission.
    • External validation demonstrated model generalizability with 87.3% accuracy and 0.922 AUROC.
    • A deep neural network model accurately stratified disease activity (remission to high) with 68.6% accuracy and 0.860 AUROC.

    Conclusions:

    • Longitudinal clinical data from EHRs are effective for developing prognostic models in RA.
    • Deep learning approaches trained on large, multicenter cohorts can accurately predict RA disease trajectories.
    • These predictive models offer a valuable tool for personalized RA patient management.
