Early Diagnosis & Preventive Care

Business Problem

A national healthcare network faced increasing patient mortality and treatment costs due to late-stage diagnosis of cardiovascular conditions. Existing diagnostic methods were reactive, relying on symptomatic reporting and standard testing that often missed early warning signs. The organization needed a scalable, accurate solution to detect heart disease risk earlier using patient data, reduce the burden on specialists, and support timely interventions.

Key challenges:

  • Delayed Diagnoses: Patients often presented with symptoms after disease progression, limiting treatment options.

  • Data Underutilization: EHRs, lab results, and imaging data were siloed and not used effectively for prediction.

  • Resource Constraints: Cardiologists and primary care physicians lacked tools to proactively identify at-risk patients.

  • Variability in Risk Assessment: Manual methods varied across locations, leading to inconsistent care delivery.

The Approach

Curate Consultant’s developed an AI-driven predictive model that analyzed structured and unstructured patient data to identify early signs of heart disease risk. Integrated into the clinical workflow, this solution enabled early diagnosis and proactive management, improving patient outcomes and optimizing the use of healthcare resources.

Key components of the solution:

  • Discovery and Requirements Gathering: Curate engaged cross-functional stakeholders—including cardiologists, data analysts, and EMR administrators—to define requirements:

    • Aggregate and clean historical EHR data for model training

    • Identify key biomarkers, lifestyle factors, and medical history indicators

    • Ensure explainable AI outputs for physician confidence

    • Support seamless integration with clinical dashboards and patient workflows

  • Model Development and Deployment:

    • Data Aggregation: Consolidated EHR, lab results, medication history, wearable data, and clinician notes into a centralized data warehouse.

    • Feature Engineering: Identified key predictors including cholesterol levels, blood pressure trends, smoking history, physical activity, family history, and comorbidities.

    • AI Model Creation: Developed a predictive risk model using ensemble techniques (XGBoost, Random Forest, Logistic Regression) trained on labeled heart disease outcomes.

    • Interpretability Layer: Used SHAP (SHapley Additive exPlanations) to provide transparent risk factor attribution.

    • Deployment: Integrated the model with clinical decision support systems (CDSS) and physician dashboards to surface real-time risk scores.

  • Workflow Integration and Optimization:

    • Proactive Screening Alerts: Physicians were alerted during patient visits if high risk was detected, prompting further tests or referrals.

    • Population Health Dashboards: At-risk cohorts were flagged for outreach, preventive screenings, and lifestyle interventions.

    • Telemedicine Enablement: Risk predictions supported remote monitoring and personalized care plans via patient portals.

    • Continuous Model Retraining: Models were refreshed quarterly with new data to improve precision and reflect changing clinical trends.

  • Stakeholder Engagement & Change Management:

    • Clinical Training: Physicians and care coordinators were trained on using AI risk scores and interpreting contributing factors.

    • Governance & Ethics Review: Models were validated for fairness, bias mitigation, and compliance with HIPAA and FDA guidelines.

    • Pilot & Iteration: Deployed initially across 5 clinics with rapid feedback loops and updates before broader rollout.

    • Change Enablement: Decision-making processes were updated to incorporate AI insights into routine care protocols.

Business Outcomes

Earlier Risk Identification


AI models flagged high-risk patients up to 12 months before traditional diagnosis methods

Improved Preventive Care Uptake


Clinics saw increased participation in lifestyle programs and early interventions, reducing progression to critical cardiac events.

Operational Efficiency


Clinicians spent less time manually reviewing risk profiles and more time on care planning, enhancing productivity.

Sample KPIs

Here’s a quick summary of the kinds of KPI’s and goals teams were working towards**:

Metric Before After Improvement
Average time to risk detection Post-symptom 5- 6 months prior Substantial lead time gained
Cardiac event hospitalization rate 11.2% 7.1% 37% reduction
Preventive screening participation 38% 67% 76% increase
Clinician adoption rate NA 88% High engagement
Patient outcomes improvement (QoL) Baseline 22% Better quality of life scores
