1. Flesch-Kincaid Grade Level: To use this formula, simply input the text into a readability calculator or software that utilizes the Flesch-Kincaid algorithm. The result will provide a reading grade level, indicating the education level required to understand the material. Healthcare providers can then adjust the content to match the desired reading level, making it more accessible to patients with varying literacy levels.
2. Simple Measure of Gobbledygook (SMOG): Similar to the Flesch-Kincaid Grade Level, SMOG requires inputting the text into a SMOG calculator. The formula focuses on polysyllabic words, so creators should aim to use simpler vocabulary to lower the SMOG score. By reducing the number of complex words, patient education materials become easier to comprehend for individuals with lower literacy levels.
3. Gunning Fog Index: To utilize the Gunning Fog Index, again, input the text into a readability tool that calculates this metric. The index considers sentence length and word complexity, so creators can adjust their writing style accordingly. Shorter sentences and simpler words can help lower the Gunning Fog Index score, making the material more readable for a broader audience.

B. Plain Language and Clear Communication:

Using plain language and clear communication techniques is essential to make patient education materials more understandable to a diverse audience. This involves avoiding complex medical jargon and technical terms, and instead using simple, everyday language that is easy to comprehend. Clear communication also includes organizing information logically, using headings and bullet points to break up text, and providing visual aids such as diagrams or illustrations to enhance understanding.

Here are some examples of using plain language and clear communication techniques in patient education materials:

1. Avoiding Jargon:
   • Instead of: “Myocardial infarction,” use “heart attack.”
   • Instead of: “Hypertension,” use “high blood pressure.”
   • Instead of: “Cerebrovascular accident,” use “stroke.”
2. Using Everyday Language:
   • Instead of: “Hemoglobin A1c,” use “average blood sugar level.”
   • Instead of: “Dyspnea,” use “shortness of breath.”
   • Instead of: “Hyperlipidemia,” use “high cholesterol.”
3. Organizing Information Logically:
   • Use clear headings such as “Symptoms,” “Causes,” and “Treatment” to organize content.
   • Break up lengthy paragraphs into shorter ones to improve readability.
4. Utilizing Bulleted Lists:
   • Presenting information in bullet points makes it easier to digest.
   • For instance:
     • Risk factors for diabetes:
       • Family history
       • Obesity
       • Sedentary lifestyle
5. Incorporating Visual Aids:
   • Including diagrams or illustrations can help reinforce key concepts.
   • For example, a diagram showing the cardiovascular system can accompany text about heart health.
6. Providing Examples and Analogies:
   • Using relatable examples or analogies can clarify complex concepts.
   • For instance, comparing the circulatory system to a network of highways and roads helps patients understand blood flow.
7. Offering Plain Language Definitions:
   • Providing definitions for medical terms within the text or in a glossary.
   • For example: “A heart attack, also known as a myocardial infarction, occurs when blood flow to the heart is blocked, leading to damage of the heart muscle.”

C. Health Literacy Considerations:

Health literacy refers to an individual’s ability to understand and act upon health information. Healthcare providers need to consider the health literacy levels of their target audience when developing patient education materials. This may involve using simpler language, providing explanations of medical terms, and offering additional support or resources for individuals with lower health literacy levels. By addressing health literacy considerations, healthcare providers can ensure that their materials are accessible to all individuals, regardless of their educational background or health literacy-related factors.
