Image-Based Communication for Strengthening Patient Health Education in Rural and Underserved Settings

Effective communication is the cornerstone of efficient patient care. It is vital to obtain a thorough history, build the patient's trust, and ensure compliance to treatment. Image-based communication (IBC) using comic-like strips is better than the conventional verbal and written modes, as it is inexpensive, less human resource dependent, and diversity agnostic. Strips based on local and socioculturally relevant issues and characters grab readers' attention, are relatable and entertaining, and utilize a storyline that invigorates thinking. The medical advice delivered by an ideal IBC strip is easy to comprehend, has a better recall, and promotes patient adherence. With an idea that IBC strips can serve as a vital supportive tool in underserved and overburdened clinics, we have described the nuances of adapting them into the existing physician-patient experience. We utilize a prototype IBC of an elderly woman helping a family whose child developed acute fever, possibly malaria. Various elements of an IBC strip, namely, panels, gutters, background, characters, bubbles, captions, and visual effects, are illustrated, and their variations are described later. Once designed, an IBC strip must be critically evaluated for the accuracy of the educational message, and errors, if any, must be corrected. The images are then subjected to a series of local field tests to ensure that they serve their purpose and have the desired cultural competence. Once ready, IBC strips can be posted in public spaces and outside clinics or distributed to healthcare workers or patients. Here, they serve as educational and health literacy tools. The strips can significantly reduce caregiver-patient interaction time and improve the quality of communication, especially when patients are illiterate or understand a different language. It is easier to develop rapport and partnership with a patient when the communication is presented through a pictorial tool. An IBC strip can be used to train grassroot workers, who subsequently train patients, thereby serving a dual purpose. To obtain tangible clinical and epidemiologic benefits from IBC strips, rigorous evidence building and standardization are a crucial long-term goal.
