A survey was conducted among foundation doctors who were in their first 2 years since graduating and were in the initial 3 weeks of their A&E rotation. This was distributed to 2 different cohorts of doctors over the period of 8 months. The survey was conducted on the web and comprised 3 case studies, each presenting a clinical vignette along with plain radiographs of the hand and wrist. The participants were required to determine if a fracture was present, specify the location of the fracture, suggest the appropriate management approach, and rate their subjective confidence in their diagnoses on a Likert scale of 1 to 10. In case of uncertainty, participants were allowed to select “unsure” as their answer. The survey also inquired whether the respondents had previously completed a rotation in trauma and orthopedics before their A&E placement. The data were anonymized and stored securely on a password-protected web-based database.

The management options for each radiograph were based on acute A&E protocols and categorized into nonoperative reduction with or without plaster or splint, operative intervention, referral to orthopedics, or no definitive management required. The cases, radiographs, and management were reviewed and checked for accuracy by the senior author (PR), a trauma and orthopedic consultant. The correct management for each scenario was determined based on the peer-reviewed guidelines from BMJ Best Practice regarding acute fracture management [12].

Respondents were informed that their responses were being collected as part of an educational study into fracture recognition and diagnostic confidence and that their responses were anonymized. No payment or compensation was made for completion of the survey.

Case 1 consists of an anterior posterior (AP) and lateral radiograph of a scaphoid fracture. The accompanying clinical vignette states: “A young male presents to A&E with wrist pain following a fall onto an outstretched hand, this is a closed and neurovascularly intact injury.”

Case 2 consists of an AP and lateral radiograph of a distal radius fracture. The accompanying clinical vignette states: “A middle aged female presents to A&E with wrist pain with a fall onto an outstretched hand, this is a closed and neurovascularly intact injury.”

Case 3 consists of an AP and lateral radiograph with no fracture. The accompanying clinical vignette states: “A middle aged female presents to A&E with wrist pain following a fall onto an outstretched hand, this is a closed and neurovascularly intact injury.”

All images for the plain radiographs were sourced under the Creative Commons license from a radiography reference website [13-15].

A total of 42 responses to the web-based survey were collected. The data obtained from these responses have been compiled and summarized in Table 1, presenting the following information for each case: number and percentage of respondents who believed there was a fracture; number and percentage of respondents who accurately identified the presence of a fracture (if one was indeed present); and number and percentage of respondents who correctly identified whether the management of the fracture required an operation.

Across all 3 case studies, the presence of a fracture was correctly identified by 62% (78/126) of respondents. However, only 48% (61/126) of respondents accurately pinpointed the location of the fracture. In 12% (10/84) of cases, fractures were entirely missed, while the correct management option was chosen in 64% (81/126) of cases.

When examining the specific fractures, 40% (17/42) of respondents correctly identified the presence and location of the scaphoid fracture, compared to 71% (30/42) for the distal radius fracture. Approximately 33% (14/42) of respondents correctly determined that the final radiograph had no fracture present.

Across all 3 cases, the correct management option was selected by 64% (81/126) of respondents. For both distal radius fractures and scaphoid fractures, the correct management options were selected by 74% (31/42) of respondents in each case.

The overall median diagnostic confidence score across all 3 scenarios was 4 of 10 (with 10 indicating full confidence), with a mean diagnostic certainty of 4.4 of 10. In the case scenario where a normal radiograph showed no fracture, respondents displayed lower mean and median confidence scores compared to the radiographs with fractures: 3.7 for the scaphoid fracture and 5 for the distal radius fracture. There was a statistically significant difference in confidence scores between respondents for the distal radius fracture and the normal radiograph (Mann-Whitney test; P=.01).

This study aimed to look at the diagnostic accuracy and confidence of foundation trainees in the A&E department in identifying common upper limb fractures and managing them. Overall, 48% (61/124) of respondents accurately identified the presence and location of fractures. The correct management option was chosen by 64% (81/126) of respondents. The median diagnostic confidence score was 4 of 10, with a mean diagnostic certainty of 4.4 of 10. Notably, respondents exhibited a significantly lower confidence score for the normal radiograph compared to the distal radius fracture radiograph (P=.01).

The ability to accurately locate fractures varied among respondents, with only 40% (17/42) correctly identifying the location of the scaphoid fracture, while 71% (30/42) accurately identified the presence and location of the distal radius fracture. It is worth noting that in clinical practice, radiographs have limitations in detecting scaphoid fractures, especially in the early stages following an injury, with a reported false negative rate ranging from 20% to 54% [16].

The proximal pole of the scaphoid is susceptible to posttraumatic avascular necrosis due to its restricted blood supply, in contrast to the distal pole [17]. Consequently, scaphoid fracture diagnoses are often missed, and this can lead to litigation in the NHS, highlighting their significance as a common cause of legal disputes [18].

These findings emphasize the challenges associated with accurately identifying and managing scaphoid fractures, underscoring the need for improved diagnostic techniques and strategies to mitigate the risk of missed diagnoses and potential complications. Enhanced awareness, thorough clinical examination, and consideration of additional imaging modalities may help improve the detection and proper management of scaphoid fractures, ultimately improving patient outcomes and reducing the associated medico-legal consequences.

The diagnostic confidence of junior doctors was found to be higher when detecting fractures compared to ruling them out. On the Likert scale, the confidence scores for the normal radiograph were recorded as 3.7, while scores of 4 and 5 were obtained for the scaphoid fracture and radial fracture, respectively. This discrepancy in confidence levels may be attributed to the limited experience of the respondents in interpreting normal radiographs.

Notably, less than one third (12/42, 29%) of the surveyed foundation doctors had previous exposure to orthopedics placements, which serve as valuable learning environments for the interpretation of plain films.

These findings highlight the impact of clinical exposure and specific training in developing the necessary skills for accurate interpretation of radiographic images. The lower confidence in identifying normal radiographs underscores the need for increased exposure and educational interventions to familiarize junior doctors with a wide range of radiological presentations, including those without apparent pathology.

The correct management option was identified in 74% (31/42) of radiographs where a fracture was present, and the overall accuracy across all 3 case studies was 64% (81/126). It is important to note that the indications for operative management of distal radius fractures and scaphoid fractures require specialized orthopedic knowledge and are typically managed in outpatient settings. However, it is worth considering that foundation doctors may have limited exposure to the clinical management of orthopedic cases in outpatient settings, which could contribute to the observed finding.

Given the complex nature of determining the appropriate management approach for fractures, further emphasis on orthopedic outpatient clinical exposure and educational interventions during training could help improve the decision-making skills of junior doctors. Enhancing their understanding of the indications for operative management and the nuances associated with different fracture types would better equip them to make informed management decisions.

Accurate interpretation of plain radiographs and appropriate management decisions are critical in the emergency department and for ongoing patient care. Prior studies have emphasized the positive impact of prompt diagnosis of upper limb injuries on quality of life and successful return to work [19].

However, studies have demonstrated significant variability in the diagnostic accuracy of junior doctors when interpreting trauma radiographs. For instance, a study conducted in the A&E setting reported an approximate incidence of misdiagnosis of 1.8% for sprained wrists [20]. A large-scale study focusing on the A&E department revealed an overall accuracy range of 59% to 73% for radiographs of the wrist and hand [1]. In our study, the overall accuracy was 48% (61/126), falling below this range.

It is crucial to acknowledge that a comprehensive clinical examination and detailed history-taking play a vital role in achieving accurate diagnoses by correlating symptoms with radiological findings. For example, tenderness within the anatomical snuffbox has been identified as the single most specific clinical marker for scaphoid fracture [21]. Additionally, thorough history-taking and clinical context have been shown to enhance the accuracy of radiograph interpretation, such as in the case of chest films [4]. It is plausible that the limited accuracy observed among respondents in our study may be attributed to the absence of such clinical information. Our findings highlight the importance of integrating focused clinical examination and history-taking alongside radiographic interpretation to improve diagnostic accuracy.

This study had several limitations that should be acknowledged.

First, the reliance solely on radiographic findings without the inclusion of clinical examination and history-taking may have constrained the respondents’ ability to accurately diagnose and manage the fractures presented. Incorporating these additional diagnostic tools could have provided a more comprehensive assessment.

Another limitation is the small sample size of 42 respondents, which may restrict the generalizability and interpretation of the findings. The study only involved a single cohort of junior doctors, potentially overlooking variations that could exist among medical graduates from different years or backgrounds.

It is important to consider these limitations when interpreting the results, and future studies should aim to address them by incorporating a larger and more diverse sample size, as well as a comprehensive clinical assessment alongside radiographic findings.

In conclusion, this study of a cohort of foundation doctors embarking on their A&E rotation highlights the variability in accurately identifying the location of fractures across different radiographs. Interestingly, the diagnostic confidence of junior doctors was found to be higher when detecting fractures compared to ruling them out. To mitigate potential diagnostic errors and ensure optimal management, it is imperative to provide close supervision and senior support. Our findings underscore the importance of implementing further teaching interventions aimed at enhancing the clinical accuracy and confidence of junior doctors in fracture diagnosis. Future research should focus on exploring targeted educational strategies that facilitate the development of robust diagnostic skills among junior doctors.
