BACKGROUND: The aim of this study was to determine the knowledge of neurosurgeons and emergency physicians about ALARA (as low as reasonably achievable) and to gain awareness to them about this topic.
METHODS: A multiple-choice survey comprising 17 questions was performed to 30 neurosurgeons and 70 emergency room doctors.
RESULTS: Emergency medicine doctors, neurosurgeons, emergency medicine residents, neurosurgery residents and general practitioners participated in the survey. Sixty-six percent of participants stated that they examined more than 50 patient with headache, dizziness and head trauma in emergency service per diem and more than half of the participants stated that brain CT was performed in the event of patient’s request, even if there was not an indication. 75% of the participants stated that they requested CT scan without neurological examination when the number of patients increased in the emergency room. Eighty-three percent of the participants did not think there was a safe dose limit in CT, 92% did not know the radiation dose received during brain CT, 96% did not know the meaning of the ALARA. Fifty-seven percent of the participants stated that if they informed about the criteria of ALARA, they will take into acount these criteria while requesting CT scan.
CONCLUSIONS: In our country, doctors working in emergency services request brain CT needlessly because of taking into account the patient’s wish and fear of malpractice. The knowledge of the neurosurgeons and emergency service doctors about ALARA is insufficient. It is necessary to educate our physicians about ALARA protocol, for taking these criteria into their consideration when requesting CT examination. For protecting the patients from the effects of ionizing radiation and reducing the economic loss of hospitals, it is necessary to increase awareness of the ALARA protocol and to increase the number of hospitals which protocol is applied.
