For the development of the service, a standard operating procedure was used. The impact of the service on therapeutic adherence, patient satisfaction and the resolution or prevention of negative outcomes associated with medication was evaluated.

There were 237 pharmaceutical interventions that increased the percentage of patients totally adherent to 84%. We resolved 82.76% of the negative outcomes associated with medication and 100% of the patients were satisfied with the service.
