Module 1

Understanding Sickle Cell Disease

Introduction

Everything else in this course builds on what you learn in this module.

Before exploring communication, cultural competence, clinical decision-making, or improving patient experiences, it’s important to understand the science behind sickle cell disease. In this module, you’ll discover how sickle cell affects the body, why pain crises occur, the different genotypes of the condition, and how biological changes influence the care people need.

By the end of this module, you’ll have a strong foundation that will help you make more confident, informed, and compassionate decisions throughout your professional practice.

What You’ll Learn

Lesson 1 – The Science of Sickle Cell

Understand what happens inside the blood, why red blood cells become sickled, and how this change in shape leads to pain and complications.

Estimated time: 13 minutes

Start Lesson

Lesson 2 – Genotypes Explained

Learn the differences between HbSS, HbSC, HbSβ⁰, HbSβ⁺ and other variants, and why genotype helps guide, but never predicts, an individual’s experience.

Estimated time: 10 minutes

Start Lesson

Lesson 3 – Sickle Triggers

Explore common triggers – dehydration, infection, cold, stress, exertion and low oxygen, and understand why prevention begins with recognising patterns.

Estimated time: 10 minutes

Start Lesson

Lesson 4 – How a Crisis Develops

From sickled cells to blocked blood vessels, oxygen deprivation, severe pain and organ damage, learn why timely treatment is essential.

Estimated time: 12 minutes

Start Lesson

Lesson 5 – A Quick Knowledge Check

Test your knowledge and understanding of sickle with a short interactive quiz covering the science, genotypes, the triggers and crisis mechanisms.

Estimated time: 5 minutes

Take The Quiz

Lesson 6 – End Of Module Reflection

Think about how what you’ve learned changes your understanding of sickle cell disease and how it might influence your future clinical practice.

Estimated time: 10 minutes

Complete Reflection

Module Learning Outcomes

Ready to Begin?

Every healthcare interaction is shaped by knowledge and understanding.
The science you’ll explore in this module provides the foundation for recognising sickle cell disease early, understanding why symptoms develop, and delivering safer, more compassionate care.
Take your time, reflect on what you learn, and remember that every new insight has the potential to improve a patient’s experience.
