Training Data

Telesoft's Healthcare AI models are trained on diverse, high-quality medical datasets that enable accurate and unbiased healthcare predictions. This documentation provides details about our training data sources, processing methodologies, and how we maintain data quality and ethical standards.

Data Sources

Our models are trained on a combination of the following data sources:

Medical Literature

  • 15+ million peer-reviewed medical publications
  • Comprehensive medical textbooks and reference materials
  • Clinical practice guidelines from major medical organizations
  • Systematic reviews and meta-analyses
  • Case reports and clinical observations

Literature data enables our models to incorporate the latest medical knowledge and evidence-based practices.

Anonymized Clinical Records

  • 2.3+ million de-identified patient cases
  • Diverse demographic representation across age, sex, ethnicity, and geography
  • Comprehensive disease coverage across medical specialties
  • Longitudinal records capturing disease progression and treatment outcomes
  • Multi-modal data including structured EMR data, clinician notes, imaging, and lab results

All clinical data is thoroughly de-identified and used in compliance with HIPAA and other applicable privacy regulations.

Medical Knowledge Bases

  • SNOMED CT clinical terminology
  • ICD-10-CM diagnostic codes
  • RxNorm medication database
  • LOINC laboratory observation codes
  • UMLS (Unified Medical Language System) concepts
  • Human Phenotype Ontology

These structured knowledge bases help our models understand and utilize standardized medical terminology and coding systems.

Medical Imaging Datasets

  • 15+ million annotated medical images across modalities:
  • X-rays (chest, musculoskeletal, abdominal)
  • CT scans (brain, chest, abdominal, full-body)
  • MRI (brain, spine, joints, cardiac)
  • Ultrasound (abdominal, cardiac, obstetric)
  • Dermatological photographs
  • Pathology slides and microscopy
  • Retinal imaging

All images are annotated by medical specialists with region-specific findings and diagnostic information.

Expert-Validated Datasets

  • Synthetically generated clinical scenarios reviewed by specialists
  • Clinical decision trees developed by medical experts
  • Validated differential diagnosis mappings
  • Symptom-condition relationship matrices with confidence ratings
  • Treatment outcome data with efficacy measurements

These curated datasets provide high-quality ground truth for model training and evaluation.

⚠️ Data Usage Compliance

All data used for training and evaluation is collected, processed, and utilized in compliance with applicable regulations, including HIPAA, GDPR, and other privacy laws. We obtain appropriate permissions and ensure data is properly de-identified and protected throughout its lifecycle.

Data Processing

Raw data undergoes extensive processing before being used for model training:

Data Cleaning

  • Removal of duplicate records and redundant information
  • Correction of data entry errors and inconsistencies
  • Standardization of units and measurements
  • Normalization of laboratory values to reference ranges
  • Harmonization of terminology across sources
  • Quality filtering based on data completeness and reliability metrics

De-identification

Patient data undergoes a rigorous de-identification process:

  • Removal of 18 HIPAA-defined protected health information (PHI) identifiers
  • Advanced methods to detect and redact indirect identifiers
  • Statistical disclosure control to prevent re-identification
  • Differential privacy techniques for aggregate statistics
  • Expert review to verify de-identification efficacy

Our de-identification methodology exceeds HIPAA's Safe Harbor and Expert Determination requirements. We regularly conduct re-identification risk assessments using advanced statistical methods to ensure data privacy.

Annotation and Labeling

Data labeling is performed using a multi-tier approach:

  • Initial labeling by medical professionals (physicians, specialists, radiology technicians)
  • Expert review and validation by board-certified specialists
  • Consensus protocols for conflicting assessments
  • Confidence scores for labeled data points
  • Quality assurance through random sampling and expert verification

Data Augmentation

We employ several techniques to enhance training data:

  • Synthetic data generation for rare conditions and edge cases
  • Medical image augmentation with domain-specific transformations
  • Simulation of disease progression trajectories
  • Patient record variation to represent clinical diversity
  • Expert-guided scenario generation for unusual presentations

All augmented data is validated by clinical experts to ensure medical plausibility and accuracy.

Data Diversity and Representation

We prioritize diverse and representative training data to ensure our models perform equitably across all patient populations:

Demographic Representation

Our training datasets include balanced representation across:

Demographic FactorDistribution Strategy
AgeComprehensive coverage across age groups, including pediatric and geriatric populations
Sex/GenderBalanced representation with sex/gender-specific medical considerations
Race/EthnicityDiverse representation with attention to race-specific clinical presentations and risk factors
Geographic LocationGlobal data representing different healthcare systems, environmental factors, and endemic conditions
Socioeconomic StatusData from diverse healthcare settings (academic, community, rural, urban, resource-limited)

Clinical Representation

Our datasets include diverse clinical contexts:

  • Common conditions with diverse presentations
  • Rare diseases and unusual clinical manifestations
  • Comorbidities and complex medical cases
  • Atypical presentations across demographic groups
  • Regional variations in disease prevalence and presentation
  • Cases across the spectrum of disease severity

Bias Evaluation and Mitigation

We actively identify and address potential biases:

  • Regular bias audits across demographic subgroups
  • Performance equity metrics tracked during model development
  • Data rebalancing to address underrepresented groups
  • Targeted data collection for performance gaps
  • Expert review to identify and correct clinical bias

Our commitment to equitable AI includes continuous monitoring of model performance across different populations. When we identify performance disparities, we implement targeted interventions including additional data collection, model architecture adjustments, and parameter tuning to ensure consistent performance across all groups.

Using Pre-trained Models

Most developers will use our pre-trained models through the API without needing to understand the intricate details of our training data. However, knowing the following principles can help you use our models more effectively:

Model Limitations

  • Models perform best on patient populations similar to training data distributions
  • Rare conditions may have lower confidence scores due to limited training examples
  • Novel treatments or recently discovered conditions may not be fully represented
  • Performance varies across different medical specialties and domains
  • Models require context-appropriate use and clinical judgment

Data Quality Considerations

For optimal results when using our API:

  • Provide as complete patient information as possible
  • Include structured data in standardized formats when available
  • Specify demographic information to enable demographic-specific analysis
  • Note any unusual circumstances or rare conditions in patient history
  • Include prior diagnostic results and treatment history when relevant
