Abstract

BACKGROUND: Observation has shown a preponderance of irrelevant, unjustified and perhaps unnecessary
radiological requests in the study area. The consequences of this on the patients' doses and population collective
dose may be dire.
OBJECTIVE: To assess Clinicians/Referrers' knowledge of radiation doses of patients undergoing radiological
examinations.
METHODOLOGY: A prospective, non-experimental, cross-sectional survey of clinicians (except radiologists) in
various hospitals in Calabar metropolis, Cross River State, Nigeria, was conducted. A pretested and validated
questionnaire was designed to extract responses on rating of effective doses for commonly requested imaging
examinations, using the value for the posterior-anterior (PA) chest x-ray as reference. Questions on
radiosensitivity of different organs, imaging modalities that use ionizing radiation and considerations for the choice
of ionizing radiation (IR) based examinations were included. Participants were also asked for their preferred
methods of filling any knowledge gap on IR issues. Responses were presented in simple percentages.
Results: A total of 104 respondents, made up of 63.5% males and 36.5% females participated in the study. At least
70% and 42% of the respondents, respectively, were aware that Ultrasound and Magnetic Resonance Imaging were
not IR based modalities. About 67.3% of the respondents did not know the doses of commonly requested
radiological examinations. This result was not dependent on clinicians' demography. A total of 61.5% of the
respondents referred patients for IR examinations even when the result was unlikely to alter their diagnosis or
treatment; but to reassure the patient (98.8% ), meet expectations of patients (35%) or to give the patient the
feeling of being taken seriously (75%).
CONCLUSION: Participating Clinicians in this study have showed poor knowledge of radiation doses of
commonly requested radiological examinations. Most participants suggested improvement of their knowledge of
radiation doses through continuous medical education and by the provision of referral guidelines.
