Clinicians' perceptions of the quality of outsourced radiology and actions taken around perceived imaging errors in practice.

OBJECTIVES: Outsourcing of radiological reporting services has fundamentally altered communication between radiologists and clinicians in clinical decision making, which relies heavily on diagnostic imaging. The aim of this study was to understand clinicians' perspectives and experiences of interpretation of outsourced reports in clinical practice, if the author of imaging reports matters to clinicians, and actions taken to deal with perceived errors. METHODS: A printed survey was distributed to a purposive sample of 50 of the 250 senior medical and surgical staff of a large National Health Service hospital in the UK who regularly engaged with the Radiology Department between May and October 2017, representing 20% of this hospital workforce. The survey consisted of ten questions examining clinicians' opinions on radiology reporting, with comment options to encourage respondents to give further detail. Participants were requested to return the survey to the study investigators. RESULTS: The survey elicited a 100% response rate (n = 50). A constant comparative framework was used to guide analysis, revealing themes relevant to the ongoing inter-professional relationship between clinicians and radiologists. The disparity between in-house and externally sourced radiology reports and underlying issues of trust surrounding outsourced reports were the most significant themes identified. CONCLUSIONS: This study found outsourcing of radiology reporting needs multi-disciplinary team availability regarding the interpretation and discussions around capacity for effective communication. It raises important issues around often under-acknowledged additional workloads imposed on in-house radiologists. There are financial and pragmatic clinical aspects in pathways of radiology practice which require further research and examination. KEY POINTS: • Utilisation of outsourcing is increasing in practice in response to imaging demands. • Outsourcing increases departmental primary reporting capacity but may increase the workload of the local radiologist. • The development of strategies for outsourcing examinations may lessen demands on the in-house workforce.

Multidetector CT improving surgical outcomes in breast cancer (MISO-BC): A randomised controlled trial.

BACKGROUND: Early diagnosis of malignant axillary nodes in breast cancer guides the extent of axillary surgery: patients with known axillary malignancy receive a more extensive single operation at the same time as surgery to their breast. A multicentre randomised controlled trial assessed whether a Computed Tomography (CT) scan of the axilla could more accurately diagnose malignant axillary lymph node involvement in patients with newly diagnosed breast cancer when compared to usual care. METHODS: Patients with newly diagnosed breast cancer (identified via screening and symptomatic pathways) at two NHS Trusts in the North East of England were recruited and randomised in equal numbers. Both groups received routine diagnostic and surgical care. In addition, one group received a CT scan of their axilla on the same side as the breast cancer. The primary endpoint was the need to undergo a second axillary surgical procedure. FINDINGS: The trial recruited 297 patients of whom 291 contributed to findings. The proportion of patients undergoing a second operation was similar (CT vs UC: 19.4% vs. 19.7%; CT-UC: -0.3%, 95%CI: = -9.5% to 8.9%, χ2 [1]: p = 1.00). Patients in the two groups were similar before treatment, had similar types and grade of cancer, experienced similar patterns of post-operative complications and reported similar experiences of care. INTERPRETATION: CT scan-guided care did not result in a change in the number of patients requiring a second operation; similar numbers of patients needed further axillary surgery in both groups. New diagnostic imaging technologies regularly enter NHS centres. It is important these are evaluated rigorously before becoming routine care.

Incidence and Potential Significance of Internal Mammary Lymphadenopathy on Computed Tomography in Patients with a Diagnosis of Primary Breast Cancer.

INTRODUCTION: The importance of internal mammary nodes (IMNs) in the staging and treatment of breast cancer patients is controversial. METHODS: A retrospective cohort of patients diagnosed with primary breast cancer over a 4-year period (January 2009 to December 2012) was assessed. The number and size of any IMNs visible on spiral computed tomography (CT) were recorded. RESULTS: A total of 830 patients were diagnosed with primary breast cancer within the identified time frame, of which 150 patients met the inclusion criteria. Of these 42% (63) had IMNs present, although the majority were small (<5 mm). However, 16% (25) had larger nodes, greater than 5 mm in short axis, present on CT. Significantly more patients with the presence of large (>5 mm) IMNs had more advanced disease with CT evidence of other distant spread. CONCLUSION: We have demonstrated that IMNs are present in a substantial number of our primary breast cancer patients. We suggest that further histological research is required to establish reliable CT size criterion for pathological IMNs. In addition, routine imaging of the IM chain, as well as axilla, should be considered in the staging of breast cancer.

Patient reported experiences of CT guided lung biopsy: a prospective cohort study.

BACKGROUND: CT guided lung biopsy is a commonly performed procedure to obtain tissue for a histological diagnosis in cases of suspected lung cancer. METHODS: This is a prospective cohort study to obtain information directly from patients about their experiences of the biopsy procedure, thus obtaining a more accurate picture of complications compared with previously performed retrospective reviews. Patients participated in a post-procedure telephone interview and information was gathered about any procedural complications and personal experiences. We also compared the patient reported complications with those obtained from a retrospective review of hospital databases, analogous to previously performed retrospective studies. RESULTS: In our patient group, reported procedural complication rates were 10% pneumothorax rate (4% requiring a chest drain) and 10% haemoptysis. Post-procedural pain and shortness of breath showed positive correlation, with one patient experiencing prolonged pain. No statistical difference was found between the patient reported complication rates and those obtained from retrospective review of the hospital database. CONCLUSIONS: Our study demonstrates CT guided lung biopsy is a safe procedure and is generally well tolerated. Some patients may experience significant and lasting pain and therefore should be counselled about this pre-procedure.

Great auricular communication with the marginal mandibular nerve - a previously unreported anatomical variant.

The great auricular nerve that originates from the cervical plexus and supplies sensation to the lower part of the auricle and the skin overlying the angle of the mandible has no motor component. During an elective neck dissection for a squamous cell carcinoma of the tongue, we found that the anterior division of the great auricular nerve divided, with a long branch that passed into the submandibular triangle anterior and superficial to the facial vein, and was joined on its deep surface by the marginal mandibular division of the facial nerve. Although anatomical variants of other branches of the cervical plexus have been described, this is, to our knowledge, the first time a communication between the great auricular nerve and a branch of the facial nerve has been reported outside the parotid gland.

Familial aplasia of the inferior rectus muscles.

PURPOSE: We describe inferior rectus aplasia in three members of a family. No family member showed signs of craniofacial dysostosis syndromes or neurofibromatosis. PATIENTS AND FINDINGS: A woman with abnormal head posture, right exotropia, and right hypotropia presented to our clinic. She mentioned that her two children had similar problems. A provisional diagnosis of ocular fibrosis or atypical Duane syndrome was made and she underwent surgery. During surgery, the inferior rectus muscle could not be identified in either eye. Subsequently, her children were examined and orbital magnetic resonance imaging (MRI) was performed for all family members. MRI confirmed bilateral absence of the inferior rectus muscles in the mother and unilateral absence with atrophic and fibrotic contralateral inferior rectus muscles in the children. CONCLUSION: This is the first report in the literature of a family with aplastic inferior rectus muscles with no signs of craniosynostosis or neurofibromatosis.
