"Emergency Department lacking in patient safety"

My sibling attended ED recently with chest pain and shortness of breath. They are in their 30’s. It is worse when they gets up and walks around. My sibling has had recent high blood pressure and tachycardia and been on numerous cardiac medications prescribed by their experienced cardiologist. It was 9am and they were already feeling lethargic, chest pain and shortness of breath. My sibling attended the ED at Nepean Hospital. I understand the staff were very vague with their tests and treatment, my sibling felt uninformed and unsupported by all staff. 

The medical staff said ‘you shouldn’t be on all these cardiac medications’ and made my sibling question the treatment on their experienced cardiologist.

The medical staff in ED discharged my sibling in the afternoon advising they can see their GP in 1-2 days. On walking to the car after leaving ED my sibling once again felt extremely lethargic, short of breath and a heaviness of pain in their chest. They felt too embarrassed to return as staff questioned their ‘anxiety and family history of anxiety.’ I believe this is a risk to patient safety.

My sibling is to see their cardiologist and spoke to their GP on the phone when they arrived home who I understand was shocked by their treatment in Emergency at Nepean and the comments made to my sibling. Their GP and cardiologist have never said or diagnosed anxiety or behavioural issues and I believe were also disappointed by this suggestion of ‘anxiety’ causing my sibling's high blood pressure and tachycardia, shortness of breath and lethargy.

They are disappointed in the treatment provided and the advice given. I believe my sibling was made to feel like they shouldn’t be there. My sibling questioned their medication regime and whether they should still take their prescribed medications. How can the local community feel supported when, in my sibling's case, they are treated like this and be empowered to look after their own health? I believe the education provided was poor on discharge, the advice throughout my sibling's visit was lacking and  based on this experience, patient safety is at risk.
