Study Notes
Informatics
- Classification: Represents terms, concepts, and their relationships systematically.
- Nomenclature: An agreed system of names assigned within specific fields.
- Terminology: Defined words or expressions relevant to a particular discipline.
-
Coding systems: Numeric or alphanumeric codes for medical diagnoses, e.g.:
- ICD-10: E11
- SNOMED CT: 16403005
Challenge of Bias in Real-World Data (RWD)
- Data collected is often used for various purposes; may lack completeness and accuracy.
- Clinicians and insurers need to be aware of potential biases in Electronic Health Records (EHR).
- Information gaps in Randomised Control Trials should be addressed, focusing on data provenance.
- Software bias may arise, such as limitations in EHR systems preventing accurate data entry.
- Data errors observed include peculiar statistics like a 1% "resurrection" rate in UK studies.
Possible Sources of Bias
-
Healthcare System Bias:
- Impact of reimbursement systems on data recording practices.
- Influence of clinician roles and adherence to professional guidelines.
- Challenges in patient access to records and data-sharing among providers.
-
Technical Factors:
- Variability in EHR functionalities and coding systems.
- Ineffective data processing and extraction methodologies.
- Workload Factors: Increased workload may impact data accuracy and consistency.
Anonymisation Techniques
- Quantitative Methods: Involve removing or aggregating variables to protect identities.
- Qualitative Approaches: Use pseudonyms or less specific terms instead of crude data removal.
- Objective is to achieve reasonable anonymisation without sacrificing data utility.
Challenges of Research Data Management
- Publishing Datasets: Lack of incentive for researchers to make datasets accessible; citation indices needed for evaluation.
- Governance Models: Outdated frameworks restrict dataset use without proper oversight; calls for more devolved approval processes.
- Awareness: Need for metadata registries to inform researchers about available datasets and their provenance.
- Capturing Provenance: Importance of documenting data provenance during analysis to enhance research transparency.
- Data Management: Necessity for coherent analytical strategies and training in health informatics.
Reproducibility Challenge
- Issues with ensuring transparency and correctness in published research findings.
- Research indicating only 25% of reviewed studies could be replicated, highlighting a critical challenge.
Reporting Standards
- Traceability and accountability in clinical research are vital.
- Established standards include:
- GxP (Good Practices in clinical data management)
- CONSORT for trial reporting
- STROBE for observational studies reporting
Learning Health System (LHS)
- Defined as systems that integrate progress in science, informatics, and culture to continuously improve healthcare quality.
- Emphasizes the need to leverage data effectively to avoid waste.
Context for Learning Health System
- Persistent issues include challenges in identifying subjects and complex data entry.
- A need for synergy between clinical trials and observational studies to address inefficiencies.
- Diagnostic errors, particularly in primary care, highlight areas requiring improvement.
- Proposed approach involves analyzing patient data and tailoring interventions to optimize health outcomes.
Summary Points
- Big Data plays a crucial role in enhancing healthcare systems and treatments.
- Understanding biases in data is essential for responsible research.
- The goal is to establish a Learning Health System that utilizes data for continuous improvement.
