Imaging: how a new paradigm is changing patient care
In this Q&A, Kees Wesdorp from Philips Diagnostic Imaging talks about imaging as an ‘ecosystem’ and how the concept of ‘empowering people behind the image’ is changing diagnostics and patient care.
Q: What do you mean by “empowering the people behind the image”?
A: With imaging, we have to look at the needs of many stakeholders – patients, technologists, radiologists, administrators – and understand their unique concerns and challenges. We think that a deeper understanding of their experience can provide important insights that help patients, clinicians and managers.
So we focus on making the process better for all the people behind the image. We work closely with customers as strategic partners to connect data, technology and people, streamlining the path to a confident diagnosis and better outcomes at lower cost.
Q: How is people-centered imaging different from patient-centered imaging?
A: Healthcare is first and foremost about patients. To make the patient experience better, everyone involved in healthcare has to work better – individually and with each other.
We know there are many people involved in the acquisition and interpretation of every image. In this imaging ecosystem, everyone has a unique set of requirements. Supporting and connecting these people in a truly meaningful manner is directly related to creating benefit for patients.
Q: Why is it important to see imaging as a system?
A: From electronic medical records to picture archiving, communications systems, clinical databases and billing systems, health data is often distributed across many applications and departments. This makes it hard to compile a comprehensive view of individual patients and populations.
We’re approaching imaging as an ecosystem in which technology and data connect seamlessly to empower all the stakeholders involved in creating diagnostic-quality images. By merging data with clinical expertise at the image processing level, we can provide the greatest value to patients, providers and health systems.
In an imaging ecosystem, patient comfort is key. Whether it’s a routine procedure or an acute situation, a patient’s level of comfort and stress can impact the diagnostic imaging process – from the physiological effects of stress on image acquisition in PET/CT1 to stress-related movement that can impede high-value, completed scans in MR and other modalities.
We recently investigated patient needs in imaging with an imaging-focused comprehensive patient study. Our research, Patient Experience in Imaging, looked at some 600 diagnostic imaging patients in terms of their satisfaction, expectations, preferences and unmet needs. The results showed three key areas that patients identified as very important: communication, comfort and safety.
Research3 into the effects of patient stress on behavioral and physiological factors critical to imaging quality reveal the significant clinical, operational and financial impact of patient-centered imaging.
In a recent article, Dr. Jennifer Kemp, diagnostic radiologist at Diversified Radiology, made a strong point that if patients are less fearful because they know what to expect, they will be better able to comply with imaging exam requirements such as holding their breath. Dr. Kemp noted how even a simple thing such as telling patients how long they are going to have to hold their breath can make a big difference.
Q: What is the financial impact when the human factor in imaging is overlooked?
A: As global healthcare spending continues to rise, cost containment in imaging will remain a major concern for health systems. There will be a focus on low-value imaging and efforts to reduce it by targeting imaging appropriateness, acquisition and quality parameters.
An investigation by Dr. Jalal Andre at the University of Washington School of Medicine identified motion artifacts (blurring of an image caused by respiratory, muscular or other patient movement) as the cause of repeated sequences in about 20 percent of MRI exams.4
He calculated the financial consequence of repeat sequences due to motion artifacts to be about $115,000 of potential revenue lost per scanner per year.
Q: How does reducing patient stress relate to the other people behind the image?
A: Patient stress affects radiology technologists who are often the one human link between patients and imaging equipment. Providing technologists with a supportive work environment may decrease burnout and increase workflow.
Radiologists face significant challenges in interpreting images, starting with the sheer number of facts they need to consider per clinical decision. Accessing relevant data, mining it and making context-driven conclusions is time consuming and stressful.
At Philips, we’re focused on innovations grounded in artificial intelligence that anticipate radiologists’ need for information and image interpretation to support confident decision-making. We have comprehensive, data-driven tools that assess operational challenges and empower people to guide more efficient and effective practice. This offers insights and directional support assisting department leadership in decision-making, helping radiology practices adapt to continuous change and creating value for the healthcare system.
An ecosystem approach is what is needed to make the most meaningful connections required toward a confident diagnosis.
