Concordance between a gastrointestinal consultant radiologist, a consultant radiologist and qualified reporting radiographers interpreting abdominal radiographs.

INTRODUCTION: Radiographers can accurately report musculoskeletal and chest radiographs, but there is paucity of research comparing the performance of reporting radiographers (RRs) with consultant radiologists when interpreting and reporting abdominal radiographs. This study assessed interobserver agreement in the clinical setting between reporting radiographers and a consultant radiologist compared to an expert gastrointestinal radiologist in a District General Hospital. Major discordant reports affecting patient management were also examined. METHODS: 126 abdominal radiographs reported by 3 RRs in clinical practice were randomly selected and reported by a consultant radiologist and index gastrointestinal radiologist. The reports of the RRs and consultant radiologist were compared against the reports made by the index radiologist for agreement by a colorectal consultant surgeon. All 126 reports were scored as being in either complete agreement, minor disagreement or major disagreement which would have resulted in a change to patient management. RESULTS: There was no significant difference in overall agreement between the consultant radiologist (CR) and RRs when compared to the index radiologist (CR: n = 90/126, 71.4% and RRs: n = 94/126, 74.6%. p = 0.57). Major disagreements were found, but there was no significant difference between both groups (CR: n = 23/126, 18.3% and RRs: n = 17/126, 13.5%. p = 0.30). CONCLUSION: RRs can report abdominal radiographs to a comparable level of agreement as a consultant radiologist in the clinical setting. There was no significant difference in reports deemed to affect patient management. IMPLICATIONS FOR PRACTICE: This study addresses the gap in assessing the performance of RRs reporting abdominal radiographs. This small scale study indicates that radiographers could provide additional support in the reporting of abdominal radiographs. This would help to reduce radiologist workload and enhance the role of the reporting radiographer. CLASSIFICATION: Agreement between reporting radiographers and radiologists interpreting and reporting abdominal radiographs.

A pilot study to assess radiographer preliminary clinical evaluation (PCE) introduced for emergency department adult appendicular X-ray examinations: Comparison of trained and untrained radiographers.

INTRODUCTION: Radiographers are transitioning from using "Red Dot" annotations to flag abnormal emergency X-ray images, to providing written preliminary clinical evaluation (PCE) diagnostic comments. This study explored the impact of local training on radiographers' PCE participation and accuracy performance during a trial period. METHODS: Ten radiographers provided PCE comments for adult appendicular trauma X-ray examinations performed in the Emergency Department of an English public hospital over a 19 week trial period. Five senior radiographers who had received local PCE training and five more recently qualified radiographers, without this local training, participated in the trial. PCE participation rates were recorded and the PCE comments were scored for accuracy compared to the formal radiology report. RESULTS: There were 796 eligible examinations, of which 528 (66%) had PCE comments. PCE participation was significantly higher (p < 0.001) for the radiographer group who received the training (80%, 253/316) compared to the untrained group (57%, 275/480). Similar levels of PCE accuracy (90% vs. 89%), sensitivity (86% vs. 82%) and specificity (91% vs. 93%) were found for the trained and untrained cohorts respectively, with no statistically significance difference between these scores. CONCLUSION: Local PCE training was associated with more frequent PCE participation but did not appear to influence PCE accuracy. The accuracy results suggest that radiographers are well equipped to provide PCE comments for adult appendicular X-ray examinations. IMPLICATIONS FOR PRACTICE: Local PCE training is likely to be important for consistent PCE scheme participation. Both experienced and recently qualified radiographers appear well equipped to provide accurate PCE for adult appendicular trauma X-ray examinations.

Accuracy of radiographer preliminary clinical evaluation of skeletal trauma radiographs, in clinical practice at a district general hospital.

INTRODUCTION: Error in interpretation of trauma radiographs by referrers is a problem which has detrimental effects on the patient and causes unnecessary repeat attendances. Radiographers can reduce errors by offering their opinion at the time of imaging. The Society and College of Radiographers have a longstanding recommendation that Red Dot (RD) schemes should be replaced by Preliminary Clinical Evaluation (PCE). The purpose of the study was to evaluate radiographer interpretation of skeletal trauma radiographs in clinical practice, determine if there was any difference in ability to interpret appendicular and axial studies, and evaluate appropriateness of PCE implementation. METHODS: A convenience sample of 23 self-selecting radiographers provided RD and PCE on 762 examinations. Each case was compared against the verified report and assigned a true negative/positive or false negative/positive value. Accuracy, sensitivity and specificity were calculated and performance measures between RD versus PCE, and appendicular versus axial were compared using Two-sample Z-Tests. Error analysis was performed and inter-observer consistency determined. RESULTS: Overall RD and PCE accuracy, sensitivity and specificity for the study were 90%, 72% and 97% (RD), and 92%, 80% and 97% (PCE) respectively. Significant difference was demonstrated for sensitivity with PCE more sensitive than RD (p-value 0.03) and appendicular more sensitive than axial (RD p-value <0.02, PCE p-value <0.0001). Most errors were false negatives. Inter-observer consistency was evaluated by review of 128 cases and no difference between reviewers was established. CONCLUSION: Radiographers without specific training were able to provide RD and PCE to a high standard. Radiographers interpreted positive findings more accurately using PCE than RD, and positive findings on appendicular cases were interpreted more accurately than those on axial cases. IMPLICATIONS FOR PRACTICE: This study supports local PCE implementation, contributes to the wider evidence base to justify transition towards PCE and identifies the necessity for local axial image interpretation training.

Agreement in the reporting of General Practitioner requested musculoskeletal radiographs: Reporting radiographers and consultant radiologists compared with an index radiologist.

INTRODUCTION: This study assessed the inter-observer agreement of reporting radiographers and consultant radiologists compared with an index radiologist when reporting General Practitioner (GP) requested musculoskeletal radiographs. The potential effect of discordant reports on patient management and outcome was also examined. METHODS: Three reporting radiographers, three consultant radiologists and an index radiologist reported on a retrospective randomised sample of 219 GP requested musculoskeletal radiographs, in conditions simulating clinical practice. A speciality doctor in radiology compared the observers' reports with the index radiologist report for agreement and assessed whether any discordance between reports was clinically important. RESULTS: Overall agreement with the index radiologist was 47.0% (95% CI, 40.5-53.6) and 51.6% (95% CI, 45.0-58.1) for the consultant radiologists and reporting radiographers, respectively. The results for the appendicular and axial skeleton were 48.6% (95% CI, 41.3-55.9) and 40.9% (95% CI, 27.7-55.6) for the radiologists, and 52.6% (95% CI, 45.2-59.8) and 47.7% (95% CI, 33.8-62.1) for the radiographers, respectively. The difference in overall observer agreement between the two professional groups with the index radiologist was not statistically significant (p = 0.34). Discordance with the index radiologist's reports was judged to be clinically important in less than 10% of the observer's reports. CONCLUSION: Reporting radiographers and consultant radiologists demonstrate similar levels of concordance with an index radiologist when reporting GP requested musculoskeletal radiographs. IMPLICATIONS FOR PRACTICE: These findings contribute to the wider evidence base that selected radiographers with appropriate postgraduate education and training are proficient to report on musculoskeletal radiographs, irrespective of referral source.

Concordance between a neuroradiologist, a consultant radiologist and trained reporting radiographers interpreting MRI head examinations: An empirical study.

INTRODUCTION: This study assessed agreement between MRI reporting radiographers and a consultant radiologist compared with an index neuroradiologist when reporting MRI head (brain/internal auditory meati [IAMs]) examinations. The effect on patient management of any discordant reports was also examined. METHODS: Two trained MRI reporting radiographers (RRs), a consultant radiologist (CR) and an index neuroradiologist (INR) reported on a random sample of 210 MRI examinations. The radiographers reported during clinical practice and the radiologists in clinical practice conditions. Two independent consultant physicians (neuro-rehabilitation and neuropsychiatry) compared these reports with the index neuroradiologist report for agreement and the clinical importance of discrepant reports. RESULTS: Overall observer agreement between the RRs and CR was comparable in relation to agreement with the INR: RR; 93/210 (44.3%); and the CR; 83/210 (39.4%) for all head MRI examinations (p = 0.32). For brain examinations the difference was similar: RR; 64/180 (35.6%); and CR; 54/190 (30.0%), p = 0.26. Agreement rates for the IAMs examinations were identical, 29/30 (97.7%). For all head MRI examinations (n = 210) there was a very small observed difference of <0.5% in mean agreement between the reporting radiographers and the consultant radiologist (p = 0.92) for examinations where a major disagreement would have been likely to have led to a change in patient management. CONCLUSION: MRI reporting radiographers reported during clinical practice on MRI head examinations to a level of agreement comparable with a consultant radiologist. IMPLICATIONS FOR PRACTICE: This is an area in which radiographers could provide additional reporting roles to the reporting service to increase capacity. Wider potential benefits include cost-effectiveness and role development/retention of radiographers.

Multi-professional image interpretation: Performance in preliminary clinical evaluation of appendicular radiographs.

INTRODUCTION: The study evaluated the performance of a cohort of healthcare professionals in image interpretation of appendicular radiographic examinations following a preliminary clinical evaluation (PCE) course. METHODS: A systematic review and meta-analysis of image interpretation performance by non-medical staff was undertaken. Thirty three participants (seven radiographers, nineteen nurses, five paramedics, and two physiotherapists) completed an image based Objective Structured Examination (OSE) following a short course on PCE of appendicular radiographs. The case bank comprised 25 appendicular radiographic examinations. Prevalence of abnormal examinations approximated 52% (traumatic conditions). The OSE test scores were analysed with Alternative Free-response Receiver Operating Characteristic (AFROC) calculation of Area Under the Curve (AUC), sensitivity, specificity, and Cohen's Kappa (k) for multi-reader agreement. Professional subgroup results were compared with Analysis of Variance (ANOVA), and compared to the literature review. RESULTS: The participant subgroup results for radiographers were sensitivity 79.7%, specificity 92.9%, k = 72; AUC 86.5. Nurses sensitivity 76.2%, specificity 80.4%, k = 56; AUC 78.3. Paramedics sensitivity 80.3%, specificity 81.6%, k = 61; AUC 81.5. Physiotherapists sensitivity 90.4%, specificity 91.6%, k = 82; AUC 91.8. ANOVA Samples scores (f = 1.5; p = 0.23), sensitivity (f = 0.5; p = 0.65), specificity (f = 2.8; p = 0.05). The comparison of the radiographers and nurses results to the published literature were encouraging (SROC AUC 93.1 and 91.2, respectively). The paramedics and physiotherapists results could not be compared to published standards or abilities on the task due to a lack of literature available. CONCLUSION: The study results of image interpretation and commentary of appendicular radiographs in an academic environment by this multi-professional sample were to a high standard, further work is recommended on a larger sample.

Radiographer reporting of neurological magnetic resonance imaging examinations of the head and cervical spine: Findings of an accredited postgraduate programme.

INTRODUCTION: To analyse the objective structured examination (OSE) results of the first cohorts of radiographers (n = 13) who successfully completed an accredited postgraduate programme in clinical reporting of neurological magnetic resonance imaging (MRI) examinations of the head and cervical spine. METHODS: Forty MRI examinations were used in the OSE which included a range of abnormal cases (prevalence of abnormal examinations approximated 50%) and included: haemorrhage, infarction, demyelination disease, abscess, mass lesions (metastatic deposits, meningioma, glioma, astrocytoma); and disc disease, cord compression, stenosis, ligament rupture, syringomyelia appearances on patients referred from a range of referral sources. Normal variants and incidental findings were also included. True/false positive and negative fractions were used to mark the responses which were also scored for agreement with the previously agreed expected answers based on agreement between three consultant radiologists' reports. RESULTS: The mean sensitivity, specificity and agreement rates for all head and cervical spine investigations (n = 520) combined were 98.86%, 98.08% and 88.37%, respectively. The highest scoring cases were cases which included astrocytoma, disc protrusion with cord compression and glioma. The most common errors were related to syringomyelia, ligament rupture and vertebral fracture. CONCLUSIONS: These OSE results suggest that in an academic setting, and following an accredited postgraduate education programme, this group of radiographers has the ability to correctly identify normal MRI examinations of the head/cervical spine and are able to provide a report on the abnormal appearances to a high standard. Further work is required to confirm the clinical application of these findings.

Superior shoulder suspensory complex fracture dislocation case report.

BACKGROUND: Acromioclavicular joint dislocation can be more complex than it first appears. The presented case had an unusual combination of injuries to the superior shoulder suspensory complex, which yielded some interesting learning points. CASE SUMMARY: The injuries were sustained after a fall from a push bike and included acromioclavicular dislocation with coracoid process, clavicle and acromion process fractures. These were identified on the initial X-ray examination, which was followed by computed tomography for surgical planning. The injuries were successfully treated by internal fixation. CONCLUSION: The unexpected complexity of the injuries could have led to subtle but important findings being overlooked. This case highlights the importance of a thorough search strategy, consideration of injury biomechanics and knowledge of associated injuries.
