An executive perspective on Point-of-Care MR Imaging.

Staffing, financial, and patient safety challenges with conventional MR neuroimaging.

Providing patients with the care they need and deserve while managing staffing and decreasing expenses is any healthcare facility’s primary focus. However, balancing these objectives is challenging when performing neuroimaging for critical patients. The traditional workflow for MR neuroimaging of critical patients requires intrahospital transport to an MR suite. Transport of critical patients is shown to significantly increase the risk of adverse events for patients, which has the potential to negatively and significantly impact quality of care and hospital expenses.

One of the most challenging aspects of transporting a patient is coordinating a specialized team to manage the patient as they move from the ICU to the MRI. Such a team typically includes two to six staff members. Further aggravating the situation, if the department is already short-staffed, taking staff away from the ICU to assist in imaging a patient could put other patients at risk. Additionally, each patient transport for imaging complicates the ICU workload, creating time-intensive patient care interruptions that require specialized nurses to remove and reattach life-sustaining equipment.

The risks and costs are well documented. According to Glavis et al., the workflow for imaging an ICU patient with conventional high-field MRI can take as long as 11.71 hours at their hospital, but other hospitals have anecdotally reported up to 24 hours. Additionally, intrahospital transport of patients is associated with numerous cardiovascular and respiratory risks that may limit timely and safe neuroimaging for critically ill patients2. And unfortunately, even under the supervision of a well-trained transport team, adverse events may still occur in 26–79% of cases during transport to imaging3,4,5,6.

Martin et al. reported that ventilator asynchrony was the most frequent adverse event and put patients at a higher risk for pneumothorax, atelectasis, and ventilator-associated pneumonia5. Difficulties occur with hardware, challenges with lifts to move the patient, issues with infusion lines, and a lack of battery life for equipment needed to support the patient7. In addition to patient impact, there are expenses associated with each adverse event. According to a study by Mello et al., the average hospital-borne cost of an adverse event is $6,255 (adjusted for inflation)8.

The complexities of the traditional workflow for neuroimaging of critical patients take a toll on everyone involved, from the risk to the patient to the stress and increased workload for the entire ICU staff (not to mention the impact on a hospital’s bottom line). What if specialized nurses could stay in the ICU with the patient—where they can take better care of the patient while maximizing the nurse-to-patient ratio in the ICU? What if neuroimaging workflow for critical patients could be more effective and efficient? What if transport-related adverse event risks and the resulting impact on length of stay and hospital expenses were not part of the equation?

Swoop®—the Hyperfine solution.

The Swoop Portable MR Imaging System enables operational efficiencies by reducing the need for intrahospital transports. Not every patient has to be transported to an MR suite when the Swoop system can bring MRI to the point of care. By bringing diagnostic MR imaging to the point of care, a Swoop system may potentially prevent adverse events related to transport and reduce patient care interruptions. The Swoop system may also contribute to reducing the length of stay (and associated costs) in the ICU by enabling clinical care teams with the potential to optimize staffing, expedite and improve patient care, and shorten the time to diagnosis. Point-of-care MR imaging can take as little as 0.5 to 5.3 hours, from ordering the scan until the images are available for assessment—a significant time reduction from the 11.7 hours it takes for traditional high-field MR imaging of critical patients.

In addition to the many patient and clinician benefits, the Swoop system is more cost-effective to own and maintain than conventional high-field MRI systems. And, unlike conventional high-field MRI, which requires specialized infrastructure and radiologic technicians, Swoop system operation, navigation, and safety training is simple, allowing for expanded user access.

For the patient, the Swoop system reduces potential adverse events associated with patient transport and brings neuroimaging to the bedside of critically ill patients too unstable for transport to radiology. The Swoop system complies with EMC emission standards and is not expected to affect most ICU equipment. Because of this, patients can remain connected to all intravenous lines and most ICU monitoring equipment as long as it remains outside the 62-inch diameter controlled access area.

For the hospital, using a Swoop system in an ICU can help optimize scheduling and increase efficiency in ICU staff utilization by reducing the time required to coordinate patient transport to radiology. Also, ICU staff can remain where they’re most needed—in the ICU at the patient’s bedside or available to assist other patients.

Additionally, a Swoop system enables clinicians to image a neuro critical care patient at the point of care, providing clinicians with real-time information to assist in critical care management decisions—without patient transport (and associated risks and costs) and without subjecting patients and staff to ionizing radiation from the portable CTs often used for serial follow-up scans.

With a Swoop Portable MR Imaging System in an ICU, hospitals have the potential to establish a new standard of care for patients too ill to transport while supporting long-term organizational goals and focusing on the best care for patients.

Studies show that the Swoop system can provide images at the point of care that clinicians have found useful for assessing:

The Swoop Portable MR Imaging System is indicated for use as a bedside magnetic resonance imaging device for producing images that display the internal structure of the head when full diagnostic examination is not clinically practical. When interpreted by a trained physician, these images can provide information that can be useful in determining a diagnosis.
