An obstetrician who worked at Sligo University Hospital has been found guilty on 17 counts of poor professional performance and three of professional misconduct by the Medical Council.
Dr Andrea Hermann faced allegations in relation to the care of six patients during 2013 and 2014.
The council also found Dr Hermann had failed to tell the hospital when she was interviewed for her post that she was required to undergo retraining and supervision, following a previous Council inquiry.
It said this showed a serious lack of candour by Dr Hermann with the council and Sligo hospital.
The council said she failed to comply with an order of the High Court and her behaviour had been disgraceful and dishonourable and was professional misconduct.
The fitness-to-practise committee heard that Dr Hermann made a number of errors in relation to patients.
In the case one patient - Patient A - the committee found that Dr Hermann had made an abnormal surgical incision during a caesarean section.
She also failed to check if a coil for the purposes of contraception was still in place in the case of Patient C, who later became pregnant.
Dr Hermann also gave a blood-thinning drug to Patient D who was already at risk of heaving bleeding.
She was found to have displayed poor surgical skill in closing up the uterus after a C-section for Patient E.
Dr Hermann was found guilty of poor professional performance with regard to the patient care allegations.
The report of the fitness-to-practise committee will now go to the full Medical Council.
It will determine any sanction that might apply.
Dr Hermann, who qualified in Germany, did not attend the inquiry.
She was legally represented for the opening of the proceedings.
The committee said today that after the inquiry concluded on 2 December, the council received an email from Dr Hermann.
It received a second email on 11 December complaining about the process.
The FTPC chairman, Michael Ryan said the committee was not minded to alter its decisions.
