Nursing Malpractice: The Basics – Part 1

Back in the old, old days, there was really no such thing as nursing malpractice. Nurses had little true responsibility, and liability largely fell to the treating physicians. But as nursing responsibilities have grown, they have become an integral part of the assessment, planning, and management of their patients.

As all trauma professionals know, our work is very complex. And unfortunately, our understanding of how the human body works and responds to injury is still incomplete. So, unfortunately, undesirable things happen from time to time.

But does every little adverse event or complication mean that someone is at fault? Or that they can/should be sued? Fortunately, the answer is no.

The law is complex, at least to professionals outside the legal field. Following are the basics of malpractice as it relates to nurses.

There are four elements that must be present for a malpractice case to be brought forward:

  1. The nurse must have established a nurse-patient relationship. Documentation provided by the nurse or other providers in the medical record must demonstrate that they were in some way involved in care of the patient.
  2. A scope of duty must be established within the relationship. For example, an ICU nurse will have duties relating to examining the patient, recording vital signs, reporting significant events to physicians, etc. The exact duties may vary somewhat geographically and even between individual hospitals. Written policies help to clarify some of these duties, but often, experts are required to testify to what the usual standards of care are when not covered by policy.
  3. There must be a departure from what is called “good and accepted practice.” The definition of this leaves a lot of wiggle room. It is defined as the care that an ordinarily prudent nurse would have provided in the given situation. It does not need to be the optimum or best care. And if there is more than one approved choice, a nurse is not negligent if they choose either of them, even if it later turns out to be a poorer choice.
  4. Finally, there must be a cause-effect relationship between the nurse’s action and the patient’s alleged injury. This linkage must be more than a possibility, it must be highly probable. For example, wound infections occur after a given percentage of operations, and it varies based on the wound classification. It’s a tough sell to bring suit for improper dressing care in a grossly contaminated wound that is likely to become infected anyway. Typically, expert witnesses must attest to the fact that the patient was, more likely than not, harmed by the nurse’s action or inaction.

What’s The Best Chest Seal For Sucking Chest Wounds?

The treatment of a “sucking chest wound” in the field has typically been with application of some type of occlusive dressing. Many times, a generic adhesive dressing is applied, typically the same kind used to cover IV sites. This is quick, easy, cheap, and readily available in the ambulance. But there is a danger that this could result in development of tension pneumothorax, because the dressing not only keeps air from getting in but also keeps any buildup of pneumothorax from getting out.

To avoid this, a number of vented products have been developed and approved by the US Food and Drug Administration (FDA). These devices have some sort of system to allow drainage of accumulating air or blood, typically a one-way valve or drainage channels. They also need to stick well to a chest wall, which may have blood or other fluids that might disrupt the seal completely.

The US Army has a strong interest in making sure the products they use for this purpose work exactly as promised. The US Army Institute of Surgical Research examined 5 currently FDA-approved products to determine their ability to adhere to bleeding chest wounds, and to drain accumulating air and/or blood from the pleural space. They developed an open chest wound with active bleeding in a swine model.

An open hemopneumothorax was created by infusing air and blood, the animal was stabilized, then additional aliquots of air and blood were infused to simulate ongoing bleeding and air buildup. The image below shows the 5 products used and the animal setup:

Here are the factoids:

  • Creation of the open hemopneumothorax caused the intrapleural pressure to move toward atmospheric pressure as expected, resulting in labored breathing and reduced O2 saturation
  • Sealing the wound with any of the chest seal products corrected all of the problems just noted
  • Chest seals with one way valves did not evacuate blood efficiently (Bolin and SAM). The dressings either detached due to pooled blood, or the vent system clogged from blood clot.
  • Seals with laminar channels for drainage (see the pig picture above) allowed easy escape of blood and air
  • Success rates were 100% for Sentinel and Russell, 67% for HyFin, 25% for SAM, and 0% for Bolin

Bottom line: Prehospital providers need to be familiar with the products they use to cover open chest wounds. Totally occlusive dressings can result in development of a tension pneumothorax if there is an ongoing air leak from the lung. Vented chest seals are preferable for these injuries. Just be aware that vented seals with drainage channels perform much better than those that rely on a one-way valve.

Flying Or Diving After Traumatic Pneumothorax: Part 2

In my last post, I wrote about the accepted management of and delay in flying due to traumatic pneumothorax. I republished the post because of the publication of a paper from Oregon Health Science University in Portland. The authors specifically tried to assess timing of chest tube removal and long-distance flight, and to measure the risk of pneumothorax recurrence or other complications.

The authors performed a retrospective review of a series of military patients who had sustained chest injuries that were treated with chest tubes over a 5 year period from 2008 to 2012. After tube removal and a pneumothorax-free period of at least 24 hours (by chest x-ray), the patients were then transported by air from the military theater back to the United States.

Here are the factoids:

  • Of 517 patients screened in the military trauma registry database, only 73 were available for study after applying exclusion criteria
  • Subjects were predominantly young and male, as one would expect from the injured military population, and 74% were injured by a penetrating mechanism
  • Median time that the chest tube was in place was 4 days, and median time from tube removal to flight was 2.5 days
  • All patients had post-flight documentation available for review, but only half (37) had in-flight documentation available
  • Nearly half (40%) had positive pressure ventilation in place during the flight
  • Five patients had “in-flight medical concerns” (4 were ventilated), but none were related to the pneumothorax. The four ventilated patients had ventilator issues, the non-vented patient had “self-limited discomfort without evidence of respiratory distress.”
  • None of the subjects developed a recurrent pneumothorax, either post-flight or over the following 30 days

The authors conclude that air travel after tube removal and a 24-72 hour observation period “appears safe.”

Bottom line: Not so fast! This is yet another small, retrospective study making grand claims. The study group is a very unique population: healthy, fit young men with penetrating injury. Your average civilian trauma patient is older, less healthy, and usually has a blunt mechanism with multiple rib fractures. In-flight documentation was not available in half of the cases. And a full medical team was present on the aircraft had a problem actually occurred.

Contrast this with a civilian patient on a commercial aircraft with very limited medical equipment and expertise on board. What could go wrong? I definitely do not recommend changing our practice on these patients yet based on this one paper. Until we have better guidance (more good papers) stick to the usual wait time to ensure a safe flight for your patient.

Does The Color Of Your Scrubs Matter?

In most hospitals, it seems that workers in every department wear a different color of scrubs. Traditionally, surgeons have worn scrubs in darker shades of green or blue. This is not always true, as some hospitals have adopted crazy colors in order to reduce theft. Apparently, not too many people are comfortable wearing a pilfered pair of bright pink scrubs in public.

We know that color can have subliminal impacts on people. Blue tends to have a calming effect. This is one of the reasons that police officer uniforms are frequently this color. Green and blue also tend to be associated with medicine. Red, orange,  and yellow are often associated with food. Ever wonder why McDonald’s arches are the color they are?

But what about scrubs? Patients do tend to form associations between a clinician’s dress and their intelligence, empathy, and trustworthiness. Interestingly, scrubs (as opposed to dress clothes) score high for all of these.

But what about the rainbow of colors that scrubs are available in? A recent research letter was submitted to JAMA Surgery by a group at UNC Chapel Hill. They administered an electronic survey over a two-month period to adult patients and visitors at their university hospital.  Their goal was to determine whether scrub color influenced the perception that the wearer was a surgeon, and what character traits were perceived.

This is a copy of the survey, asking for the identification of the surgeon, and the most skilled individual based on scrub color.

The results were quite interesting. This is a chart of trait identification based on color for men. The chart for women was very similar. Note that taller bars are a negative.

Here are the factoids:

  • Half of participants were 30-60 years old, and the remainder were evenly split between younger and older people
  • Green was the color most associated with surgeons and was selected by nearly half of participants. Sex did not seem to matter.
  • Black had the most negative connotation of any color
  • Blue scrubs were associated with the most caring clinicians; however it also implied that they were less knowledgeable, less skilled, and less trustworthy

Bottom line: This is an intriguing little study that shows that unfortunately, looks do matter. Even the colors of our clothes do! The participants associated black with death and said they looked like a mortician’s uniform. So definitely avoid!

The poor perception of clinicians wearing green scrubs is difficult to explain, but consistent. The navy and blue characteristics were generally positive and don’t look appreciably different from each other.

Hospitals pay little attention to the color of the scrubs they purchase. But this choice may have an impact on how the wearer is perceived by patients and families. Perhaps it is time to rethink color in patient-facing clinicians. And avoid black scrubs like the plague!

How To Avoid Missed Injuries

I’ve just spent two days here looking at the phenomenon of “delayed diagnosis” or missed injury. I believe that there are only two fundamental reason why this occurs:

  • Insufficient diagnostic technique – A good physical exam and/or specific diagnostic techniques were not performed. Or rarely, the injury cannot be readily detected by existing techniques and technology. The former is usually the real problem, and may be an issue with either the physical exam completeness and/or technique, or judgment used to obtain the appropriate diagnostic test. Example 1: a penetrating injury to the back is missed because the patient is not logrolled to examine this area. Example 2: a spine fracture is missed in an elderly patient with a fall from standing because the back pain found on physical exam is evaluated only with conventional imaging of the spine, not CT.
  • Failure to recognize the injury – The injury was actually identified on a test, but was not appreciated by the clinician. Example 1: the radiologist may not have appreciated and reported out a subtle anomaly in the cervical spine imaging. Example 2: you fail to check you patient’s lab tests and miss a sudden spike in serum amylase or lipase the day after your patient was kicked in the epigastrium by a horse.

So what can you do to avoid this potential problem? Here are some tips:

  • Admit that it can really happen to you. If the missed injury rate at your center is off the low end of the bell curve (< 5%) then you are either really good or really blind. You’d better take a close look at your performance improvement process, because you may be fooling yourself.
  • Adopt a firm definition of “delayed diagnosis.” Basically, you need a time frame after which a new diagnosis is considered “delayed.” It should be a reasonable time interval after the patient has left the ED. If it’s too short an interval (e.g. once they leave the ED), your number will be unnecessarily high. If it’s too long (days and days later), then significant morbidity may occur that you don’t account for. Most centers have adopted 24, 36, or 48 hours after patient arrival.
  • Implement a tertiary survey process. This is a complete physical re-examination followed by a review of all diagnostic studies (lab and radiology) that have been performed. This exam needs to be dated and timed to ensure that it is performed within the time frame noted above. If a new finding is discovered on the tertiary survey, it is not considered a delayed diagnosis. If found after the survey (or after the pre-determined time interval), it is and must be entered into your performance improvement process.
  • Be paranoid. I hate the phrase, “maintain a high index of suspicion” because it’s meaningless. It’s like those stupid “start seeing motorcycles” bumper stickers. You can’t see what you can’t see. But you can be suspicious all the time, constantly looking for the inevitable clinical surprises of trauma care.
