[The review of the treatment of a very complex patient easily finds areas for improvement. Case report]. / La revisión del tratamiento de un paciente muy complejo fácilmente encuentra aspectos mejorables. A propósito de un caso.

Case presentation: A 100-year-old male presented with an episode of profound bradycardia. The patient's carer alerted the emergency department and they withdrew the bisoprolol and controlled the bradycardia. Once the problem was resolved, we were asked if any of his medications could be related to the bradycardia. Assessment and evaluation: On reviewing all the patient's treatment, which is very complex, we cannot establish a clear relationship between any of his 19 drugs and the bradycardia, except for the bisoprolol already withdrawn, but we found 6 other problems that we tried to solve. Results: Of the 6 proposed changes, 3 are accepted. Final comment: The review of a complex treatment will probably allow us to detect some aspects that could be improved.
