Abstract

The referral is the key source of information that enables radiologists and radiographers to provide quality services. However, the frequency of suboptimal referrals is widely reported. This research reviews the literature to illuminate the challenges suboptimal referrals present to the delivery of care in radiology departments. The concept of suboptimal referral includes information, that is; missing, insufficient, inconsistent, misleading, hard to interpret or wrong. The research uses the four ethical principles ofnon-maleficence, beneficence, AutonomyandJusticeas an analytic framework.Suboptimal referrals can causeharmby hindering safe contrast-media administration, proper radiation protection by justification of procedures, and compassionate patient care. Suboptimal referrals also hinder promoting patientbenefitsfrom the correct choice of imaging modality and protocol, an optimal performed examination, and an accurate radiology report. Additionally, patientautonomyis compromised from the lack of information needed to facilitate benefit–risk communication. Finally, suboptimal referrals challengejusticebased on lack of reasonable patient prioritising and the unfairness caused by unnecessary examinations.These findings illuminate how suboptimal referrals can inhibit good health and well-being for patients in relation to safety, missed opportunities, patient anxiety and dissatisfaction. The ethical challenges identified calls for solutions. Referral-decision support tools and artificial intelligence may improve referral quality, when implemented. Strategies addressing efforts of radiology professionals are inevitable, including gatekeeping, shared decision-making and inter-professional communication; thereby raising awareness of the importance of good referral quality and promoting commitment to ethical professional conduct.
