Adherence
Adherence to the treatment generally shows whether the patient complies with the instructions and directions of the physician in terms of medication, nutrition, exercise and overall disease management.
It has been observed, since ancient times, that patients often ignore the medical advice. A typical example is the one of Hippocrates who warned the practitioners to oversee the patient’s errors that make them reluctant to tell the truth about treatment compliance. In fact, almost all chronic conditions face high rates of non-adherence and those with no visible symptoms, such as depression, have the lowest adherence rates. Poor patient adherence may lead to insufficient treatment a fact that may also lead to significant costs for the healthcare system increasing the admission to the hospital.
