Misdiagnosis in healthcare, particularly in emergency settings, is a critical issue that has far-reaching consequences for patients and healthcare systems alike. The introduction of advanced, cost-effective imaging technologies at the point of care is revolutionizing the way diagnoses are made, improving accuracy, reducing wait times, and minimizing unnecessary radiation exposure.
The Problem of Misdiagnosis
Diagnostic Errors in Minor Injuries Units
As the pressure on Emergency Departments (EDs) continues to rise, patients with relatively minor injuries are increasingly being redirected to Minor Injuries Units (MIUs) or are triaged by specialist nursing teams. These teams have the authority to request and review imaging services, which can significantly reduce waiting times and allow emergency resources to be focused on the most seriously ill or injured patients.
However, despite these benefits, the number of “missed fracture” claims facing the National Health Service (NHS) has notably increased in recent years. Between 2015 and 2018, such claims cost the NHS over £1.1 million (NHS Resolution Report, 2022). The reasons for these misdiagnoses vary, but consistent failings have been identified across England, including diagnostic errors, particularly in the early stages of soft-tissue injury diagnoses, and issues with imaging requests, reporting, interpretation, and follow-up.
Resource Pressures and Clinical Judgment Mistakes
One of the most concerning aspects highlighted in the NHS Resolution Report is the growing responsibility placed on specialist nursing teams to triage patients. The majority of errors reported were due to clinical judgment mistakes, with incorrect initial diagnoses leading to crucial X-rays not being requested in nearly half of the cases.
While the role of advanced nurse practitioners and radiologists in initial triage and diagnosis offers many advantages for patient flow, the necessary checks and balances to ensure any errors are quickly identified are not always in place due to resource pressures. For instance, if a triage team misdiagnoses a soft-tissue injury when a fracture is present, imaging may not be requested, leading to inappropriate treatment and potentially severe consequences for the patient.
NICE guidelines, such as NG38, emphasize the need for a radiologist, radiographer, or trained reporter to provide a definitive written report of Emergency Department X-rays of suspected fractures before the patient is discharged. However, when staffing levels and resources are insufficient, these safeguards are not always realized, increasing the risk of missed injuries and suboptimal patient outcomes.
The Role of Advanced Imaging Technologies
The Importance of “Right Imaging, Right Place, Right Time”
The introduction of advanced imaging technologies is crucial in addressing the challenges of misdiagnosis and resource constraints in healthcare settings. Both NICE and the Royal College of Emergency Medicine emphasize the importance of “right imaging, right place, right time” diagnostics. This approach aims to improve patient outcomes by ensuring that the appropriate imaging is conducted at the most effective time and location.
Adaptix 3D Ortho Imaging System
One of the most promising new technologies is the Adaptix 3D ortho imaging system. This system provides point-of-care, low-cost, low-dose 3D diagnostic imaging of extremities. Unlike traditional 2D X-ray systems, which may miss certain fractures, the Adaptix system uses a miniaturized Flat Panel X-ray source combined with an image reconstruction algorithm, developed in partnership with the University of Oxford, to offer superior imaging quality.
The Adaptix system’s Flat-Panel array emits X-rays from multiple angles, allowing depth information to be presented in DICOM format. This “sweeping” technology enhances the “Z” resolution, improving the overall image quality and enabling more accurate diagnoses. The system is compact, weighing just 15 kg and measuring 15 x 11 cm, making it highly portable and suitable for use at the point of care, whether in a waiting room, by the patient’s bedside, or even in an ambulance or community setting.
Benefits of New Imaging Technology
Enhanced Diagnostic Confidence
One of the key benefits of the Adaptix 3D ortho imaging system is the enhanced diagnostic confidence it provides to clinicians. By offering 3D imaging at a cost and radiation dose similar to existing 2D systems, the technology reduces the need for patients to undergo expensive and time-consuming MRI or CT scans. This not only improves diagnostic accuracy but also accelerates the treatment process, leading to better patient outcomes.
Point-of-Care Accessibility
The portability of the Adaptix system allows for greater accessibility to 3D imaging at the point of care. This means that patients no longer need to be moved around the hospital for imaging, reducing the risk of worsening injuries or cross-infection. With image acquisition times of just 5-10 seconds and almost real-time image reconstruction, clinicians can review images quickly, leading to faster diagnosis and treatment.
Cost-Effectiveness and Workflow Efficiency
In addition to improving diagnostic accuracy and patient care, the Adaptix system is also highly cost-effective. Its ability to provide high-quality 3D imaging at the point of care reduces the need for expensive imaging technologies, such as MRI and CT, and decreases waiting times for imaging services. This accelerated workflow not only saves costs but also enhances the overall efficiency of healthcare services, allowing resources to be better allocated to where they are most needed.
Conclusion
The integration of advanced imaging technologies, like the Adaptix 3D ortho imaging system, into healthcare settings, represents a significant step forward in reducing misdiagnosis and improving patient outcomes. By providing the right imaging at the right place and time, these technologies offer a cost-effective solution to the challenges posed by resource constraints and increasing patient demand. As healthcare continues to evolve, the adoption of such technologies will be crucial in ensuring that patients receive the best possible care, without unnecessary delays or costs.
