Read the first 7 Data Collection Methods flashcards as text

  1. Which type of data collection error occurs when a site coordinator records '120/80' in the diastolic blood pressure field instead of the systolic field?

    Answer: Field placement error

    Placing data in the wrong field is a field placement error, distinct from transcription or omission errors.

  2. What is the function of a Data Management Plan (DMP) in relation to data collection?

    Answer: It outlines the processes, tools, responsibilities, and timelines for managing clinical data throughout the trial

    The DMP is the comprehensive document that governs all data management activities including collection methods, timelines, and quality controls.

  3. In risk-based data collection, which factor would MOST increase the monitoring intensity for a particular data point?

    Answer: The data point is the primary safety endpoint with direct patient impact

    Data points that are primary safety endpoints with direct patient impact are classified as high-risk and require more intensive monitoring.

  4. When a clinical trial uses a central laboratory, which data collection step ensures that lab results are correctly attributed to the right patient and visit?

    Answer: Proper specimen labeling with unique subject and visit identifiers

    Unique specimen labels containing subject ID and visit information are critical to ensuring correct attribution of laboratory results.

  5. Which approach to data collection helps ensure that endpoints derived from imaging studies are assessed consistently across all trial sites?

    Answer: Using a central independent review committee with predefined assessment criteria

    Central independent review committees apply uniform, pre-specified criteria to imaging data, reducing variability and bias across sites.

  6. A data manager notices that a site has submitted CRFs with dates written in MM/DD/YY format while the protocol requires DD/MMM/YYYY. What is the BEST course of action?

    Answer: Issue a query requesting the site to confirm and correct the dates to the required format

    Issuing a query to the site ensures that dates are confirmed and corrected in the proper format, maintaining data integrity and audit trail.

  7. What is the significance of capturing 'not done' versus leaving a field blank in a clinical CRF?

    Answer: 'Not done' indicates the assessment was intentionally skipped, while a blank may indicate a data entry omission

    Distinguishing 'not done' from a blank field preserves the reason for missing data, which is critical for statistical analysis and regulatory review.
