No further info is available… (3003768277‐2011‐00485). The name and product code identify the generic category of a device for FDA. These reports included both patients who were not provided hearing protection and patients for whom hearing protection was provided. The categories in Table 1 were defined based on known and common hazards within the MR environment and expected adverse event types.4, 24-26. To help readers understand our report classifications, we provide example excerpts from report narratives included in our study. Four hospital staff members, including the attending radiologist, have been arrested in connection with the case, according to Indian news and media site … For example, if one were searching for infusion pump malfunctions that occurred within the MR environment, it is likely that a different set of adverse events would be retrieved when searching for infusion pumps within the MRI product code versus searching for MRI within the infusion pump product code. The son was initially treated at the imaging center and then sent to a different hospital where the bullet was removed from his leg (2183553‐2017‐00005). Fifteen events were referred to the third reader for adjudication. The technician suffered a laceration to the right index finger requiring 10 sutures (3002808157‐2017‐10156). The final root cause categorization of the thermal injuries is given in Table 4. Accompanied by an anesthesiologist, the child was receiving sedation for the MRI via an infusion pump with a long IV tube. Less severe traumas also can cause serious nerve damage. As the number of magnetic resonance imaging scanners in the country has soared from a handful in 1980 to about 10,000 today, and as magnets have quadrupled in power, careless accidents … Thus, the potential benefits of an MRI scan are life-saving. Therefore, we recommend that hearing protection be provided and used correctly during all MR examinations. For attribution to an object as the root cause, the location of the thermal injury needed to match the location of the object, A thermal injury attributed to skin‐to‐skin contact at two anatomic locations, or a report describing thermal injuries in two anatomical locations that are likely to have be in direct contact (e.g., inner thighs, left and right calf, thumb, and ipsilateral hip) leading to a possible current loop, Thermal injury occurring at an anatomic site in contact with (or near) the bore of the MR system, Thermal events that are clearly not RF‐related, for example, fires and cryogen burns, The root cause of the event was unknown or the event description includes insufficient detail to draw any conclusions. The final categorical breakdown of the 1548 events is given in Table 3. A major limitation of this retrospective study is that the adverse event reports are derived from a passive reporting system17 that relies on information provided by users of the devices and other sources, and therefore some information about certain events may be missing, inaccurate, or unverified. The patient's finger was lacerated and required stitches (3002808157‐2017‐98018). The majority of mechanical injuries we encountered in our analysis — finger pinch events from the patient table, falls, and injuries to technologist from moving heavy items — was not specific to MR systems. The burn was approximately 1.5 inches in diameter. 2019 Apr 2;16(7):1186. doi: 10.3390/ijerph16071186. The finger of the patient was pinched between the table top and the magnet bore cover, resulting into [sic] a fracture of the finger (3003768277‐2016‐00106). ASRs for the analyzed timeframe were also queried and verified to not include any MRI system data. Electronic mail: jana.delfino@fda.hhs.gov; Telephone: (301) 796‐6503. Japanese Journal of Magnetic Resonance in Medicine. At a later date, the patient reported back to the customer that she has a buzzing sound in her ears. It is important to remember that devices which have been shown to be safe within a defined set of use conditions (i.e., MR Conditional devices) can heat and lead to patient injury under other conditions.25 Skin‐to‐skin contact RF loop burns were observed between the thumb and the buttocks or hip area, between the patient's inner thighs, between the calves, and between the hands of patients positioned with crossing arms. The U.S. Food and Drug Administration has received nearly 400 reports of MRI-related accidents over the past decade. A survey showed 52 per cent of American MRI facilities reported accidents this year. Imaging technicians working with MRI scanners may be at an increased risk of commuting (near) accidents. Methods: FDA and device manufacturers are only able to identify trends and initiate meaningful follow‐up when sufficient information is provided to allow meaningful conclusions to be drawn. Effects of static magnetic fields on cognition, vital signs, and sensory perception: a meta-analysis. An analysis by a health services research firm found 389 MRI-related incidents from 1995 to 2005. It was reported that the site was experiencing image quality issues. Patient had an MR procedure. A delay in the delivery of necessary care is another potential health consequence of inadequate or unavailable images. 2014 Jun;71(6):423-9. doi: 10.1136/oemed-2013-101890. First-Stroke Patients’ 5-Year Survival Rates Study Another study analyzed 836 patients who suffered their first stroke between 1997 and 1998 in … In 2014, a technician at another hospital in Mumbai spent 4 hours wedged inside an MRI … Magnetic Resonance Imaging (MRI) exams help physicians diagnose a range of conditions by producing images of internal organs and structures of the body. The patient was seen by her physician and found to have a small amount of hearing loss (2183553‐2017‐00023). Patient had a MR exam. A patient sustained fractures of the 10th and 11th anterior ribs while being positioned for a MR examination of the breast… (2183553‐2016‐00028). February 5, 2018 — Investigations are underway at a hospital in Mumbai, India, after a man was killed when he was sucked into a magnetic resonance imaging (MRI) machine while carrying a metallic oxygen cylinder into the exam room. A surprising finding of our analysis was that the MRI coils used in the examination were often cited as the likely cause of burn injuries, such as when coils were routed directly over the patient, patients were in contact with coil cables or baluns, or when only sheets or blankets were used to separate coil cables from the patient.  |  No additional information is available at this moment… (3003768277‐2011‐00338). Immediately after the scan, a second degree burn with a 2–3 cm blister was observed at the place there [sic] the coil cable was touching the patient… (3003768277‐2009‐00059). Users outside FDA can access MedWatch reports through an adverse event database,20 while MedSun reports are archived separately in the MedSun database.21 Identifying information is redacted from publicly facing databases before records are made public. Conclusion: Immediately after the exam, third degree burns were observed under the ECG pads. Discrepancies in event categorization were flagged and discussed with the aim of reaching agreement on the appropriate categorization of a flagged event. Within FDA, all device adverse event reports are archived in a database called the System for Uniform Surveillance (SUS). The number of reports we reviewed without sufficient information to permit categorization underscores the importance of complete, detailed reports. The gun then became attracted to the magnet. Also, the clips of the pads were melted (3003768277‐2010‐00057). Patient was having an MRI of his shoulder. It was reported that a patient had hearing loss after an MRI of the brain. LOWELL — In a freak accident during an MRI scan at Lowell General Hospital Saints Campus last month, a hamper flew toward the machine’s large magnet, striking a patient and leaving the … While attempting to remove the drip stick, the technician was pinned between the drip stick and the magnet. Site brought patient into scan room on a ferromagnetic gurney. The patient had a MR procedure. Schaap K, Christopher-De Vries Y, Crozier S, De Vocht F, Kromhout H. Ann Occup Hyg. Results: Author to whom correspondence should be addressed. For this analysis, SUS was queried to retrieve all adverse event reports received by FDA between 1 January 2008 and 31 December 2017, inclusive, for MR imaging systems (FDA product code LNH), MR specialty coils (FDA product code MOS), NMR spectroscopy (FDA product code LNI), and PET/MR systems (FDA product code OUO). The effect was seen on commuting accidents that had occurred on the commute from home to work as well as accidents from work to home or elsewhere. The majority of these events have known causes and are thus preventable. The FDA recognized the public interest in this information and modified the conditions of the ASR Program in 2017 to require submission of a companion report on the official mandatory reporting form.19 Companion reports included the total number of events being summarized in the quarterly report through the ASR Program and are available publicly.20. Accidents occur at MRI facilities daily, from the seeming-innocuous screening incidents to the potentially fatal missile events. The shim filter was attracted to the magnet when the service engineer tried to remove it from the examination room. Occupational exposure of healthcare and research staff to static magnetic stray fields from 1.5-7 Tesla MRI scanners is associated with reporting of transient symptoms. Conversely, some reports pool information about more than one event, so a single report cannot be assumed to contain information about a single event. Millions of MRI scans are performed each year. The MR environment involves a large static magnetic field, pulsed gradient magnetic fields, and radiofrequency (RF) fields, all of which interact with body tissues and devices present within the imaging field and may create translational and torqueing forces, heating of tissues and devices, stimulation of muscles and nerves, and hearing damage. The technologist has recovered but retains a scar on his fingers (2183553‐2014‐00003). These events described a patient death attributed to malfunction of an implantable pain pump after exposure to the static field of the MR system, a field service engineer crushed by a blower panel that became a projectile, and a field service engineer who went into cardiac arrest while under anesthesia for follow‐up treatment of a cryogen burn. The MAUDE web search feature20 only makes accessible the 10 most recent years of data. Office of In Vitro Devices and Radiological Health, Center for Devices and Radiological Health, US Food and Drug Administration, 10903 New Hampshire, Ave WO66-Rm 4236, Silver Spring, MD, 20993 USA. We analysed all of the MRI injury accidents reported to the FDA via their MedWatch program in 2015 and 2016 and tested which preventions would be most effective in keeping patients and staff safe. Industrial Injuries Disablement Benefit is help if you're ill or disabled from an accident or disease caused by work - eligibility, how to claim. Our goal was to use this information to increase awareness of the unique safety challenges that are inherent in the MR environment. Driving Strengths & Weaknesses Across America. The Food and Drug Administration (FDA) has received nearly 400 reports of MRI-related accidents over the past decade, Chassin says. The study authors found that the lifetime risk of breast cancer deaths with no screening is 10%-11% across models. One injury type specific to MR systems is broken ribs in patients undergoing breast exams (22 reports). When patient was removed from MRI machine, MRI tech observed a 1/2" blister on his right thumb and right thigh. During an MRI exam, a sedated patient sustained a cut finger from an open space between the bridge and the magnet cover near the front opening. However, there are still so many interesting tidbits that the general public does not know about MRI scans. In partnership with the Society for Magnetic Resonance Technologists (SMRT), the FDA has developed a series of posters addressing MRI safety key aspects for … Exposure to acoustic noise is an often‐overlooked MRI hazard. It was not possible in our analysis to differentiate between receive‐only RF coils and transmit/receive accessory coils. Please enable it to take advantage of the complete set of features! COVID-19 is an emerging, rapidly evolving situation. The categories in Table 2 are mutually exclusive. Mission Statement: Salmaniya Medical Complex strives to continuously meet the Secondary and Tertiary Health Care needs of the citizens and residents of Bahrain in the most effective and efficient manner possible and at the highest level of quality within its available resources. Therefore, all events were placed into one of the above mutually exclusive categories based on agreement of two out of three reviewers. Doctor was notified. Forms for reporting to FDA can be found on FDA's website.16. The patient had a MR exam. The purpose of this article was to provide an overview of 10 yr (2008–2017) of FDA adverse event reports for MR systems. Key Elements of Clinical Magnetic Resonance Imaging Safety. During a service action at the magnet, a trained … engineer sustained serious cryogenic burns on his hand (3003768277‐2015‐00097). Our cross-sectional study indicated an increased risk of (near) accidents if imaging technicians had worked with MRI in the year prior to the survey (odds ratio OR 2.13, 95%CI 1.23-3.69). Our shared safety goal should be to bring the preventable adverse event rate to zero. International Journal for Quality in Health Care. Immediately after the examination, second to third degree burns appeared on the inside of his calves (3003768277‐2009‐00083). Mechanical events — defined as slips, falls, crush injuries, broken bones, and cuts; musculoskeletal injuries from lifting or movement of the device — (11%), projectile events (9%), and acoustic events (6%) were also observed. A patient's finger got injured while being moved into the bore of the MR system. User facility reports can be found in the MedSun database,21 not in MAUDE. These reports included patients who developed tinnitus, hearing loss, or both, on either a transient or permanent basis. Bongers S, Slottje P, Portengen L, Kromhout H. Magn Reson Med. Immediately after the scan, a second degree burn with a blister, size of approximately 3 cm × 6 cm, was found on patient's back (right side). Miscoded events were those reporting problems with a device other than an MR system or accessory (for example, a spectroscopic blood analyzer).  |  This result needs confirmation and potential risks for other groups (volunteers, patients) should be investigated. Medical device manufacturers must submit an adverse event report to FDA within 30 calendar days of becoming aware that the device they market may have caused or contributed to a death or serious injury, or when the device has malfunctioned, and this device or a similar device that the manufacturer also markets would be likely to cause or contribute to a death or serious injury if the malfunction were to recur.14 User facilities must submit an adverse event report within 10 working days of becoming aware that a device has caused or may have contributed to the death or serious injury of a patient at the facility.15 FDA accepts voluntary reports from anyone who wishes to alert the FDA to a problem with a medical device. A device product code is a unique three letter identifier assigned by FDA23 and referenced when the adverse event is reported.
