Teen Dies From Peanut Reaction Despite Epinephrine Injections

By ThinkReliability Staff

Even with the best medical treatment known provided quickly after an anaphylactic reaction, a teen died after taking a bite of a snack containing peanuts, to which she was severely allergic. It is important to note that the snack was not clearly marked to contain peanuts and it was a style of treat (Rice Krispies) that would not ordinarily contain peanuts.

In a situation requiring emergency response, it is important to ensure that all the prescribed steps were taken.  The required steps can be diagrammed visually within a Process Map.  In this case, all available actions were taken to attempt to reverse the allergic reaction. (View the Process Map of the appropriate food allergy response by clicking “Download PDF” above.)

For reasons as yet unknown, food allergies have been increasing over recent years.  This has resulted in a greater risk for anaphylactic reactions, which can result in serious injury and even death, usually from throat closure from swelling (known as severe laryngeal edema).

According to John Lehr, the Chief Executive Officer of  Food Allergy Research & Education:  “Avoidance is the only way to avoid a reaction, but we know accidents happen.  That’s the insidious nature of food allergies.”

Because avoidance is the only way to avoid an anaphylactic reaction, many schools and other public facilities have stopped offering any food containing peanuts.  Others have designated peanut-free zones to help those with allergies avoid contact with peanuts.  (Although peanut allergies are not the most prevalent, they are the most dangerous, both from reaction severity and likelihood of contact.)  Certainly, snacks containing peanuts must be clearly marked as such.

Because of the high risk of serious injury or even death from food allergies,  please pass the word about food allergies.  If you are an allergy sufferer, ensure that you have multiple epinephrine auto-injectors that have not expired.  It may save your life.  (Although up to 40% of anaphylaxis victims require two or three epinephrine injections, death after receiving injections is extremely rare.)   Also note, from John Lehr:  “We tell people that their last reaction is not an indication of their next reaction.  Don’t think because you have not had a severe reaction that you can’t have one.”  If you provide food to the public or children, consider removing peanuts from your  kitchen and at the very least, clearly mark anything that does contain peanuts.   Remember, the risk from food allergies is very real, and can be very severe.

Root Cause

Patient Dies After Fall During Transfer

By ThinkReliability Staff

A medical center in California received a fine for an adverse event in which a patient’s fall at the facility resulted in his death.  As a part of the investigation into these types of events, a plan of action to mitigate the risk of similar events occurring in the future.  In order to best determine which events will be helpful in decreasing future risk, a full accounting of the cause-and-effect relationships that led to the incident being investigated can be helpful.  We can develop a visual map of the causes that resulted in this incident in a Cause Map, a visual form of root cause analysis which determines all relevant causes in order to offer the most possible solutions.

We begin our analysis with a summary of the “what, when and where” of the event, as well as determining which of the organization’s goals were impacted.  In this case, the patient safety goal was impacted due to the patient death.  The compliance goal is impacted because the facility was found to be noncompliant with requirements for licensure as a result of this event.  The fine from the state health department can be considered an impact to the organizational goal.  The patient services goal was impacted due to the improper transport of a patient.  Lastly, it was found that equipment was missing necessary safety features.  This can be considered an impact to the property/ equipment goal.

Once we have determined the impacts to the goals, we can begin with one impacted goal and ask “Why” questions to  determine the cause-and-effect relationship that led to the impacted goals.  In this case, we begin with the patient safety goal.  Why was the patient safety goal impacted? Because of a patient’s death.  Why did the patient die? His death was due to rib fractures and internal bleeding.  Why? Because of blunt force trauma.  Why? Because the patient fell out of a geri/bed chair (a device that can be used as a stretcher semi recliner or chair).

To ensure that the causes we include in our analysis are accurate, we include evidence wherever possible.  Evidence allows validation of the inclusion of causes on the Cause Map.  In this case, the evidence for the cause of death is provided by the autopsy report.

In addition to continuing to ask “Why” questions to add more detail to the Cause Map, we can also add additional impacted goals to the Cause Map.  For example, the patient fall out of the geri/bed chair was what caused the noncompliance with licensure that is an impact to the compliance goal.  This noncompliance caused the fine to the facility.   The patient fell out of the geri/bed chair due to inadequate transport, which impacted the patient services goal.

In some cases, more than one cause is necessary to result in the effect.  The inadequate transport was caused by the patient – who had been assessed as a high fall risk – being both left unattended and not secured in the geri/bed chair.  The patient was not secured on the geri/bed chair because it did not have straps.  It’s also possible he was not secured, and was left unattended, because the transport team, who took him to the radiology department to get an X-ray, was not aware of his high fall risk.  Although a transfer form is used to turn the care of a patient over to another team in cases such as this, there was no record on the transfer form that indicated a report being made to the transfer team that would have included information about the patient, including his fall risk.

As part of the investigation, corrective actions are required.  As is typical in these cases, many of the solutions included additional training and education to staff to reduce the risk of these events happening again.  Although usually included as part of the corrective actions for adverse events, training (or re-training) and continued education are some of the least effective solutions in terms of error recurrence.  (After all, presumably the staff had already been trained on the policies and requirements that were already in place at the time of the accident.)  More effective solutions include changes in policy that result in increased patient safety.  For example, in this case the transport policy has been updated to ensure that patients are left in locations where they can easily be monitored.  This of course will not prevent all falls, but may prevent some, and will certainly lead to staff noticing falls quickly.  Even more effective are changes in equipment to make following policies easier.  In this case, the geri/bed chair that was used for patient transport did not have a strap, even though its use was required.  It is unreasonable to expect busy staff to spend their time searching for equipment that has the proper safety equipment.  Rather, ensure that all geri/bed chairs or other transport devices have the required safety devices.  I’m sure you can imagine that it is much more likely for staff to comply with a policy requiring use of safety devices when the devices are available and by doing so, will reduce the risk of patient falls, and patient deaths.

Root Cause

Woman Dies After Neck Trapped Between Mattress and Bed Rail

By ThinkReliability Staff

On January 26, 2013, a nursing home resident died of positional asphyxiation after her neck became trapped between her bed’s mattress and a bed rail.  The nursing home was cited for neglect by the state for not evaluating whether or not the use of a bed rail is appropriate.

The cause-and-effect relationships that led to the resident’s death can be diagrammed in a Cause Map, or visual root cause analysis.  This allows all the issues related to the incident to be examined so that as many potential solutions as possible can be considered, increasing healthcare reliability.

The first step in the Cause Mapping method is to capture the what, when, and where of the incident, as well as the impacts to the organization’s goals.  A nursing home’s goals include ensuring residents’ safety,  employees’ safety, residents’ quality of life, and compliance with regulatory and other accrediting agencies.  In this case, the resident safety goal was impacted because of the resident death.  The resident quality of life was impacted because there was no assessment performed to ensure the use of bed rails was appropriate.  Because that assessment was not performed, the facility was fined by the state Health Department.  Additionally, the compliance goal was impacted because both the Centers for Medicare and Medicaid (CMS) and The Joint Commission prohibit the use of bed rails when used as restraints.  CMS also will not reimburse for treatment for injuries related to the use of bed rails.

Beginning with an impacted goal, asking “Why” questions aids in developing the cause-and-effect relationships that resulted in the impact to the goal.  In this case, the resident death was caused by positional asphyxiation because the resident’s neck was caught between her bed rail and mattress.  The asphyxiation also resulted from the resident not being found immediately.  In this case, there were forty minutes between the last nursing check and when the resident was discovered.

The resident’s neck was caught because she was unable to free herself due to limited mobility and dementia and the use of bed rails.  In this case, as previously noted, an assessment to determine whether the use of the bed rail was appropriate had not been performed.   Presumably the bed rail was used because of the resident’s history of falls. Despite research that the risks outweigh the benefits when using bed rails as restraints (as opposed to mobility aids for residents who are cognitively and physically able), the FDA has stopped short of requiring a safety label on bed rails.

The nursing home involved in this incident has provided an approved plan to reduce the risks of this type of incident recurring.  Beyond that particular facility, states Minnesota Commissioner of Health Dr. Ed Ehlinger,  “As a result of this death, we want all health settings where bed rails are used to take immediate steps to make sure they are following the correct guidelines around bed rails, grab bars and other devices.”

Root Cause Analysis

Young Boy Killed by Projectile During MRI

By Kim Smiley

It has been over ten years since six year old Michael Colombini died as a result of injuries that occurred during a routine MRI.  He was undergoing a post-surgery MRI after removal of a benign brain tumor when he was hit by a magnetic oxygen tank that was pulled toward the MRI machine at high speed.  His skull was fractured and he died two days later.

How did this horrible accident happen?

A Cause Map, or visual root cause analysis, can be built to help explain the causes that contributed to this death.  In this example, the patient needed an MRI because he had a brain tumor removed and he was hit by a magnetized oxygen tank while in the MRI machine.  This occurred because the oxygen tank was attracted by the huge magnet in the MRI and flew towards the machine at high speed.

MRI magnets will always attract magnetic things, even when the machine is off.  Bringing a magnetic oxygen tank into a MRI examination room is a dangerous situation.  In this example, there are several reasons why the tank was brought into the MRI area.  The tank was bought into the room by a well-meaning nurse who heard the anesthesiologist calling for oxygen.

The nurse had returned to the MRI area in order to retrieve something she had left there earlier in the day when she had accompanied a patient to the space.  She heard the anesthesiologist calling for oxygen and saw the tanks nearby so she handed one to the doctor.  Contributing to this accident is the fact that the oxygen tanks were stored near the door to the MRI exam room.

The anesthesiologist was calling for oxygen because the patient had low oxygen saturation levels and needed additional oxygen.  The patient was a six year old boy so he had been sedated for the MRI procedure.  A piped in system normally supplied oxygen for use during MRIs, but the system had malfunctioned.  Both MRI techs on duty had gone to investigate the piped in oxygen system failure so nobody trained on MRI safety was around when the nurse bought in the oxygen tank.

Some simple solutions that might have helped prevent this accident, even with the oxygen system failure include storing oxygen tanks far away from the MRI exam room and not allowing unescorted non-MRI staff into the space.  It’s also always a good idea to have an acceptable back up for important systems planned in advance.  If a second safe oxygen supply was already provided, this accident could have been prevented.

The magnets in MRI machines are 200 times stronger than a refrigerator magnet and, as this example illustrates, the potential for injuries from projectiles is very real. Like most accidents, this death was caused by a number of failures that occurred at the same time.  All of the staff involved was trying to do the right thing, but the end result was the unnecessary death of a young boy.
