Arrived in the emergency room for my 85 year old father with vagual discomfort.
The nurses are great.
On the other hand, the doctor waited a long time for the blood tests.
A chest x-ray was taken and found a lung infection.
Being a dialysis person, he prescribed him an antibiotic of 500 mg per day.
The doctor still missed a pericarditis ...
The next day he left for dialysis and with the doctor's credit and blood tests.
He was hospitalized the same day for a CT scan and a heart echo after they realized that the prescribed dosage was not sufficient. And that my father had percarditis.
Emergency I understand, but as many medical errors no verification of the blood test (even if I brought back my medical files with the last 6 results). It would be desirable for medical interns to be really supervised by competent people given their levels ... Because let's not forget that these are life and people they manage and not pieces of meat.
