Patient Dataset Overview AI Prompt

This prompt is designed for a first-pass assessment of a patient-level healthcare dataset before any downstream analysis begins. It helps the analyst understand whether the file is organized at the patient, encounter, or admission level, what core clinical domains are available, and whether there are obvious data integrity issues that could bias later findings. It is especially useful because healthcare data often mixes repeated encounters, multiple identifiers, and clinically implausible values in ways that are not obvious from a simple schema review.

Prompt text
Give me a complete overview of this patient dataset. Include:
- Total number of patients and total number of records (are there multiple records per patient?)
- Key demographic columns: age distribution, sex breakdown, race/ethnicity if present
- Date range of the data and what time period it covers
- Clinical identifiers present: patient ID, encounter ID, admission ID
- Key clinical columns and their data types: diagnoses, procedures, medications, lab values, vitals
- Missing values per column (%)

Flag any immediate data quality concerns specific to healthcare data:
- Implausible clinical values (e.g. age > 120, heart rate = 0, negative lab values)
- Patients with unusually high record counts that may indicate data duplication
- Date inconsistencies (discharge before admission, future dates)

When to use this prompt

Use case 01

when you first receive a new patient-level extract and need to understand its structure

Use case 02

when you need to confirm whether records are unique by patient, encounter, or admission

Use case 03

when you want a healthcare-specific data quality screen before deeper analysis

Use case 04

when you are preparing a handoff note for analysts, clinicians, or data engineers

What the AI should return

A structured dataset overview with patient and record counts, key identifiers, major clinical domains, date coverage, missingness profile, and a short list of immediate healthcare-specific data quality concerns.
