Health Literacy Interventions
Albert Einstein once stated "If you can't explain it simply, then you don't understand it well enough." This quote sets a high bar for medical professionals in terms of knowledge, but this sentiment an essential requirement for communicating effectively with patients having low health literacy. For example, if a patient previously diagnosed and treated for HIV / AIDS has subsequently presented with a below normal BMI, hypotension, specific oxygen in the low 90% range, high HIV viral load, very low CD4 count, and is afebrile, there is a good chance that the patient has not been adhering to treatment recommendations.

It was clear that literacy was a significant health barrier for this patient, but not intelligence.
Among the many possible communication barriers patients can suffer from, the above patient had only a few. These included language barriers, language of nursing, medical and scientific jargon, and inadequate prior communications. The communication process depends on the following elements: (1) message, (2) sender, (3) receiver, (4) encoder, (5) channel, (6) decoding, and (7) feedback loop. Based on the information provided by the above patient, the communication process failed during the initial diagnosis and treatment because the message was not adequate to the task.

Due to the lack of sufficient message, the…
