DA0-002 Data Acquisition and Preparation Practice Question
A healthcare organization collects patient questionnaire data via paper forms at clinics. The forms are scanned and sent to a central office, where staff manually enter data into an electronic system. This process is slow and error-prone. The organization wants to reduce manual entry errors and speed up data availability. Which method should they adopt?
⚠ Common exam trap
The trap here is assuming that any automation (like outsourcing or online forms) solves the problem, but the question specifically asks for reducing manual entry errors and speeding data availability, which OCR directly addresses.
Answer choices

Correct answer & explanation
✓
Use optical character recognition (OCR) to digitize the forms and automatically populate the database
Using optical character recognition (OCR) to digitize the paper forms and automatically populate the database directly addresses the goal of reducing manual entry errors and speeding up data availability. OCR converts scanned images of text into machine-readable data, eliminating the need for manual transcription and enabling faster processing. This method is well-suited for structured forms like patient questionnaires.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Continue manual entry but double-check all entries
Why it's wrong here
Double-checking entries keeps every keystroke and both verification passes in the manual workflow, so transcription errors and the delay before data availability remain. It is tempting as a low-cost control, and would be reasonable for a small volume of high-risk fields where automated capture is genuinely unavailable.
- ✓
Use optical character recognition (OCR) to digitize the forms and automatically populate the database
Why this is correct
OCR converts scanned glyph images into machine-encoded text, then template or field mapping populates the database directly, eliminating the transcription step where staff introduce keystroke errors. This satisfies both stated constraints: fewer manual entry errors and faster data availability, since digitisation occurs at scan time rather than awaiting central-office keying.
- ✗
Send forms to an external data processing company
Why it's wrong here
Outsourcing still requires the paper forms to be scanned, shipped and re-keyed by the vendor, so manual transcription errors persist and turnaround lengthens rather than shortens. It is tempting because business process outsourcing suits high-volume back-office processing where internal capacity, not accuracy, is the binding constraint.
- ✗
Require patients to fill out forms online at home
Why it's wrong here
Collecting responses online at home removes clinic staff from the capture step but shifts the burden onto patients, who may lack devices, connectivity or accessibility support, and it does not digitise the existing paper workflow at the point of care. It suits scheduled pre-visit intake, not walk-in questionnaire collection.
