The adherence results from a balance between the
perception of the need to take medication and concerns
about their adverse effects.
Improve adherence to medication is a highly effective
strategy for better health outcomes, thereby obtaining
better benefits in quality of life, than to invest in new
medicines.19 In the cost-benefit analysis of adherence to
medication, the estimates indicate that for every additional
dollar spent on adherence the costs would decrease by
7 dollars in diabetics, 5.10 in patients with hyperlipidemia
and 3.98 in patients with hypertension.2,7
The nurses because of their intervention, the intensity of
the relationship with the patient and their families, the
informality that characterizes their interactions, which is
highly valued by them, have a privileged space for intervention
in the context of multidisciplinary performance.
Thus, the behaviour changes in health require a number of
strategies that depend on the level of knowledge of people
regarding their health, their beliefs, their behaviours, their
confidence levels, the strength of their social support
networks, their levels of motivation and environmental
factors.
