The quality of a given service in a surgical department depends on many factors. Most important are adequate resources, training of the surgeons and nurses and time for follow-up and clinical research. Quality standards should be defined in accordance with the international literature and results should be continuously surveyed to ensure that the agreed goals are met. This article describes various general rules and routines which have been established in our department, as well as the specific systems used to measure the quality of our surgical service in three special fields: Care of patients with tumour mammae, care of patients with gallstone disease, and prospective registration of complications for all gastroenterological patients in our surgical department.
