The council restored 420 doctors to the Medical Register last year.
279 complaints against doctors were submitted to the Medical Council last year.
That's a sharp drop from 421 in 2019.
In its annual report, the Medical Council Annual Report indicates that some of the complaints received in 2020 relate to two or more practitioners.
One GP was struck off, three had conditions attached to their registration and seven were advised, admonished or censured following an inquiry.
Some 1,160 new doctors were registered from 2019 to 2020 with 24,720 doctors now on the Medical Register.
420 doctors were restored to the Medical Register to help during the Covid-19 pandemic after having responded to the ‘Be On Call for Ireland’ campaign.
Leo Kearns, Chief Executive of the Medical Council, joined Clem Ryan on Thursday's edition of Kildare Today.
