The Signposting Toolkit uses visual highlighting to help staff quickly identify high-risk symptoms and important information. Colour-coded phrases and prominent high-risk buttons ensure critical cases are noticed immediately.

High-Risk Symptoms

High-risk symptoms are those requiring urgent attention or immediate clinical assessment. The system provides quick access to these symptoms through prominent buttons and clear visual indicators.

High-Risk Quick Buttons

High-risk quick buttons provide instant access to urgent symptoms directly from the homepage and symptom library.

Button Styles

• Pill Style — Rounded pill-shaped buttons
• Tile Style — Square tile buttons with icons

Users can choose their preferred style in preferences.

Benefits

• One-click access to critical symptoms
• Consistent placement for muscle memory
• Visual prominence ensures visibility
• Customisable appearance

High-Risk Configuration

Admins can configure which symptoms appear as high-risk buttons:

Configuration Options

• Select symptoms to feature
• Customise button order
• Add custom high-risk symptoms
• Remove non-applicable options

Best Practices

• Limit to most critical symptoms
• Keep list manageable (5-10 buttons)
• Review regularly for relevance
• Update as pathways change

Highlight Engine

The highlight engine automatically colours key phrases in symptom instructions, making important information stand out at a glance.

How It Works

The system scans instruction text for specific phrases and applies colour-coding automatically. This happens in real-time when instructions are displayed.

Built-in Highlighting

The system includes built-in recognition for common phrases:

Slot Types

• Orange slot — Standard appointments requiring booking
  • Background: Orange
  • Text: White
  • Usage: Regular appointment bookings
• Red slot — Urgent appointments
  • Background: Red
  • Text: White
  • Usage: Same-day urgent care
• Pink/Purple — Specific service types
  • Background: Purple
  • Text: White
  • Usage: Specialised services
• Green — Community or pharmacy pathways
  • Background: Green
  • Text: White
  • Usage: Self-care or community services

Custom Highlight Rules

Surgeries can create custom highlight rules to colour-code any phrase they choose.

Rule Configuration

• Phrase — Text to highlight
• Text Colour — Foreground colour
• Background Colour — Background colour
• Enabled/Disabled — Toggle rule on/off

Use Cases

• Local service names
• Specific referral pathways
• Surgery-specific terminology
• Important warnings or notes

Rule Precedence

Custom rules take precedence over built-in highlights. This ensures local preferences override defaults when needed.

Highlight Colours

The system uses a consistent colour palette aligned with NHS design principles:

Colour Meanings

While colours can be customised, the default meanings are:

• Orange — Standard appointments, routine care
• Red — Urgent care, same-day appointments
• Pink/Purple — Specialised services, specific pathways
• Green — Community services, pharmacy, self-care
• Blue — Information, general guidance

Accessibility

All highlight colours meet WCAG 2.1 AA contrast requirements:

• Minimum 4.5:1 contrast for text
• 3:1 for large text and icons
• Accessible to colour-blind users
• Clear visual distinction

Configuration
