High therapeutic success at low costs. Incorrect or unnecessary prescriptions, dosages that are too high or too low, drug interactions: the list can go on indefinitely. Medication errors lead to approximately half a million emergencies in hospital admissions each year. When pharmacists and doctors take responsibility for medication together with the patient, the error rate decreases, the success of therapy increases, and costs for society decrease. The competencies you can showcase as a pharmacist are illustrated by these cases taken from the namesake series of the German Pharmacists' Journal: a patient with polypharmacy, a patient with cardioembolic stroke, a multimorbid patient with left heart support system, a patient with gastric ulcer, a patient with restless legs syndrome, and a multimorbid patient.
