Guidance – Date Input and Display
These Design Guides are two of nine documents relating to patient demographic data which have been adopted by the
Information Standards Board for Health and Social Care (ISB)
as a full standard for implementation in healthcare systems.

Introduction
The Design Guidance – Date Display document
provides you with guidance and recommendations for displaying single, precise dates
in clinical applications. It enables unambiguous date display, while enhancing patient
safety and clinical application usability, by eliminating confusion between day,
month and year elements.
Dates can be displayed in short and long formats. The short format is commonly used
as it prevents international users from confusing day and month elements and presents
the dates in a concise, easily readable and unambiguous form.
The Design Guidance – Date and Time Input document provides you with guidance
and recommendations for entering date information in clinical applications.
The accurate entry of dates is a fundamental function within clinical applications,
and, in many cases, has safety implications for patients within clinical and administrative
processes. The guidance given enables unambiguous date entry, while enhancing patient
safety and clinical application usability by:
- Providing a clear mechanism for guiding the user towards entry of an accurate value,
therefore reducing human error
- Providing efficient input controls for the user to enter values in a fast and easy
manner
Summary
The Date Display guidance focuses on displaying the date element and includes recommendations
for:
- Displaying the short date format (used where the clinical application displays patient-related
dates)
- Displaying the long date format (used within application output for non-clinical
readers)
The Date Input guidance focuses on date input and includes recommendations for:
- Entering unknown, exact, fuzzy, or arithmetic shortcut values using free text
- Entering exact and fuzzy values using a calendar
- Editing the date elements independently
- Displaying instructional text for different types of date entry
- Labeling date entry controls
- Disambiguating free text date entries
- Combining date and time controls
