3.10 Data-Collection Methods and Tools

The two most commonly used collection methods are paper-based and electronic recording.

• Paper-based methods are still widely used for vital registration, surveillance and research purposes.
  • Potential advantages:
    • May be cost-effective for low-resource settings
  • Potential disadvantages:
    • More prone to human error, since transcription is required
    • Requires more time to collect and transfer data
• Electronic methods are improving as technology evolves. The ideal electronic collection tool should be able to collect data and provide data securely to a data management centre for storage and analysis.
  • Potential advantages:
    • Improves record accuracy
    • Allows quick data transfer to a data management centre
    • Identifies missing data in a timely manner
    • Ability to take and transfer digital photographs
  • Potential disadvantages:
    • More vulnerable to theft
    • Can compromise privacy/security if data are not encrypted
    • Requires training on how to use an electronic system
