The world of medicine has an abundance of knowledge and practical advice for the general public. Unfortunately, the limited interactions between the two make it difficult to impart all the information there is to share. In order to solve this problem, many medical offices turn to models, posters, and charts in their patient areas. Waiting areas, exam rooms, and consultation rooms are full of diagrams and scale models of different anatomy and disease prevention. However, in the age of the Internet, could it be that digital media is replacing these simple tools? Here’s a look at the role of charts and posters in the medical environment.

Is There a Downside?

First, it’s important to ask if there is a downside to including informative charts and posters in medical environments. Even if there are more effective ways to communicate information, there are no negative consequences to using visual educational materials. Additionally, there are demographics of patients, such as the elderly and those without internet, who may not encounter the information any other way. Some may consider charts and posters outdated. However, they cause no harm and can undoubtedly benefit at least some patients who encounter them.

Posters and Charts Are Effective for Teaching

In 2013, the Health Information and Libraries Journal published a review in which researchers surveyed all known studies on the effectiveness of poster presentations. The common conclusion among the collected studies was that these visual tools are effective “in increasing knowledge, changing attitudes and behavior” when included with other forms of education. While no studies compared charts and posters to different types of training, researchers correlated posters and a marked increase in knowledge transfer of valuable information.

Presentation and Location Are Important

While charts and posters have been shown to be effective, not all visual tools are created equal. For example, a poster that is overly crowded with information or a chart that is complicated and difficult to read will be less likely to assist in education. The previous journal review states it this way: “Although superficial, the graphical design and physical appearance of the poster can determine its success in promoting knowledge transfer.”  Locating posters in a medical environment lends them credence. But it is also essential that the media delivers the information well and in an attractive way. This way, it is sure to grab patients’ attention.

Ultimately, charts and posters are an excellent and inexpensive tool for medical professionals. They are a simple, passive way to pass on vital information to the general public. While the world continues to grow more digital each day, it appears that there is still an essential role for the charts and posters we all know.
