Study Overview
This systematic review highlights the increasing importance of AI methods in enhancing data quality within healthcare. Covering 30 publications from 2020 to 2025, the study focuses on how AI addresses critical data quality dimensions like accuracy, completeness, consistency, timeliness, uniqueness, and validity.
It emphasizes that the success of AI algorithms is fundamentally dependent on the quantity and quality of available data, underscoring the need for robust data quality management to prevent flawed models and poor decision-making.
Critical Data Quality Dimensions
The research identified six key dimensions of data quality, with varying emphasis in the literature:
- Accuracy: Most frequently addressed (49%), crucial for reliable AI outcomes.
- Consistency: Highly emphasized (16.6%), ensuring data structural stability.
- Completeness: Significant focus (15.1%), addressing missing data.
- Timeliness: (9.8%) Ensuring data is up-to-date for real-time applications.
- Uniqueness: (6.3%) Identifying and eliminating duplicate records.
- Validity: (3.4%) Ensuring data conforms to defined rules and formats.
AI Methods & Approaches
Various AI techniques are employed to tackle data quality issues in healthcare:
- Supervised Learning: (Regression, Classification) Widely used for accuracy and timeliness.
- Deep Learning: (CNN, RNN, GAN) Effective for accuracy, especially in noisy or incomplete data.
- Natural Language Processing (NLP): Key for accuracy, uniqueness (entity resolution), and textual data validation.
- Isolation Forest: Applied across accuracy, consistency, and uniqueness for anomaly detection.
- Data-centric AI: A cross-cutting approach for consistency, completeness, and validity.
- Federated Learning & Ontology-based Governance: Essential for privacy-preserving and semantically structured approaches in sensitive domains.
Addressing Key Challenges
Poor quality data in healthcare can lead to flawed AI models and poor decision-making, directly impacting patient safety.
- Model Dependence: AI success is directly tied to data quality.
- Traditional Limitations: Model optimization often overlooks data quality issues like incompleteness or bias.
- Generalizability: Geographic and institutional biases (e.g., APCs limiting low-resource contributions) can hinder the broader applicability of AI solutions.
- Ethical & Conceptual Gaps: While technical capabilities are strong, alignment with complex concepts like explainability, fairness, or validity remains limited.
Strategic Solutions & Future Directions
The research advocates for systematic and algorithmic methods to significantly increase AI accuracy and reliability.
- Data Quality Improvement: Application of AI for cleaning, harmonization, and bias reduction.
- Cross-cutting Methods: Approaches like Isolation Forest and Data-centric AI can address multiple quality issues simultaneously.
- Privacy & Semantic Structuring: Federated learning and ontology-based governance are crucial for sensitive healthcare data.
- Inclusive Research: Promoting equitable access to publication and broader international participation to reduce biases and improve solution representativeness.

Case Study: AI-Powered EHR Data Harmonization
An enterprise healthcare provider struggled with inconsistent and incomplete patient data across disparate Electronic Health Record (EHR) systems, leading to diagnostic delays and treatment errors. By implementing a Data-centric AI approach combined with NLP-based entity resolution and deep learning models (CNN/RNN), they achieved significant improvements.
The AI system automatically identified and corrected data inaccuracies, harmonized inconsistent terminologies, and imputed missing values based on contextual understanding. This resulted in a 25% reduction in data entry errors and a 15% increase in diagnostic accuracy, demonstrating the tangible impact of AI on healthcare data quality and patient care.
