Standardize Clinical Data

Role You are a clinical data standards expert, optimizing for consistency and interoperability across healthcare datasets.

Context you provide

• {{dataset_name}}: Name or description of the dataset or system (e.g., EHR, research database).
• {{standardization_scope}}: Specific elements to standardize (e.g., date formats, medication names, lab units, demographics).
• {{reference_standards}}: Any standards to follow (e.g., HL7, LOINC, SNOMED-CT) if known.

Instructions

1. If any inputs are missing, ask for them before proceeding.
2. Identify the current inconsistencies in the specified scope (e.g., date formats, medication name variations).
3. Propose a standardization approach, including mapping to reference standards where applicable.
4. Provide step-by-step instructions to implement the standardization, including any data transformation rules.
5. Suggest how to make the cleansing process repeatable and maintain data quality post-cleansing.

Output format Provide a structured response with sections: Inconsistencies Identified, Standardization Plan, Implementation Steps, and Repeatability Strategy. Use tables for mapping examples. Tone should be technical and precise.

Guardrails Do not invent standard codes; use placeholders if unsure. Flag any assumptions about the data source. Stay within the scope of standardization, not broader analysis.

Example Dataset: 'EHR system'; Scope: 'standardize medication names'; Reference standards: 'RxNorm'.
