Without evidence of benefit, an intervention should not be presumed to be beneficial or safe.

Protecting Systemic Incompetence – Part I

 

We demand the lowest standards, because we are willfully ignorant and we do not want to understand. The surprise is that so many of us survive our devotion to incompetence. The loudest voices tend to dominate the discussions and the loudest voices demand that their excuses for incompetence be accepted. The rest of us don’t oppose incompetence enough.

A nurse was told to give 2 mg Versed (the most common brand of midazolam in the US) for sedation for a scan, intended to give 1 mg Versed, but actually gave an unknown quantity of vecuronium (Norcuron is the most common brand in the US). The patient was observed to be unresponsive and pulseless by the techs in the scan. A code was called. The family learned the details from a newspaper article, not from the hospital.
 

A Tennessee nurse charged with reckless homicide after a medication error killed a patient pleaded not guilty on Wednesday in a Nashville courtroom packed with other nurses who came in scrubs to show their support.[1]

 

The nurse intended to give a medication that should be limited to patients who are monitored (ECG and waveform capnography), because different patients will respond in different ways. This is basic drug administration and deviation from that basic competence may even have been common in this Neuro ICU (Neurological Intensive Care Unit). We demand low standards, because we do not want to understand.

We don’t need to monitor for that, because that almost never happens.

Except these easily preventable errors do happen. And we lie about it. We help to cover it up, because we demand low standards, regardless of how many patients have to suffer for the benefit of our incompetence.

This is a common argument used by doctors, nurses, paramedics, . . . . It makes no sense, but we keep demonstrating that we don’t care.

The people in charge should act responsibly, but they delegate responsibility and we reward them.

Back to the hospital, Vanderbilt University Medical Center (VUMC) is a university medical center, so the standards should be high. VUMC was founded in 1874 and is ranked as one of the best hospitals in America.

There is a drug dispensing machine, from which less-than-killed nurses can obtain almost anything and administer almost anything, without understanding enough to recognize the problem. This is an administrative problem. This was designed by someone with no understanding of risk management.

The over-ride of the selection is not the problem, because emergencies happen and it is sometimes necessary to bypass normal procedures during an emergency. Ambulances are equipped with lights, sirens, and permission to violate certain traffic rules for this reason.

Some of the many blatant problems are:

* The failure of the nurse to have any understanding of the medication supposed to be given

* The failure of the nurse to recognize that the drug being given was not the drug ordered.

* The failure of the nurse to monitor the patient being given a drug for sedation.

* Most of all, the failure of the hospital – the nurses, the doctors, the administrators, to try to make sure that at least these minimum standards are in place.

* How often do nurses in the Neuro ICU give midazolam?

* Why is a nurse, who is clearly not familiar with midazolam, giving midazolam to any patient?

* How is a nurse, working unsupervised in a Neuro ICU not familiar with midazolam?

* What kind of qualifications are required for a nurse to give sedation without supervision?

* Since this nurse was orienting another nurse, what qualifies this nurse to orient anyone?

* Given the side effects of midazolam, why was midazolam ordered without monitoring?

* Given the side effects of midazolam, was it the most appropriate sedative for use in a setting where monitoring is going to be difficult?

* Was it the more rapid onset of sedation, in order to free up the PET scan more quickly and/or avoid having to reschedule the scan, that led to the choice of midazolam?

* How well do any of the doctors understand the pharmacology of midazolam if they are giving orders for a nurse to grab a dose, take it down to the scan, give the drug, and return to the unit, abandoning the monitoring of the patient to the techs in the PET scan?

* This is not a criticism of the techs in PET scan, but are techs authorized to manage sedated patients?

* Even though they will often scan sedated patients, are the techs required to demonstrate any competence at managing sedated patients?
 

The nurses being oriented apparently thought that it is customary to give sedation:

1. without even looking at the name of the medication

2. without confirming by looking at the name again, it before administration

3. without double checking with a nurse, or tech, that the label matches the name of the drug to be given
 

How many of the doctors, responsible for the care of ICU patients, would agree to be sedated, without being monitored, and to have their care handed off to PET scan technicians?

Why didn’t the doctors and nurses see this as a problem before it made the news?

If the problems were reported, nothing appears to have been done to address the problems beyond the usual – Nothing to see here. Move along. or That’s above your pay grade.

That is the primary point I am trying to make.

The problem is well above the pay grade of the nurse.
 

Here is the part that experienced nurses have jumped on immediately:

Why did the nurse think that midazolam needs to be reconstituted?

Vecuronium (most common brand name is Norcuron) is a non-depolarizing neuromuscular-blocker, which comes as a poweder, that needs to be reconstituted.

1. Read label instructions?

This nurse has repeatedly demonstrated a need to be supervised, but those responsible for that supervision have apparently ignored their responsibilities in a way that far exceeds any failures by this nurse.

Is it possible that this is a one time event and that the nurse has behaved in an exemplary manner at all times while around doctors and other nurses before this day? It is possible, but the number and severity of the failures on the part of the nurse strongly suggest a pattern of not understanding, not caring, or both. I suspect that any lack of caring is due to a lack of understanding, because I have not yet lost all hope in humanity.

Are We Killing Patients With Parochialism?

 
The variation in approaches to resuscitation in EMS is tremendous.

Many excuses center around the need for local people to be able to claim that they know something that the evidence does not show, although they consistently fail to provide valid evidence for these claims. This local knowledge appears to be intuitive – they just know it, but cannot provide anything to support their feelings.

The latest research can be interpreted in many different ways, but it definitely does not support the claims of the advocates of parochialism.
 

Results We identified 43 656 patients with OHCA treated by 112 EMS agencies. At EMS agency level, we observed large variations in survival to hospital discharge (range, 0%-28.9%; unadjusted MOR, 1.43 [95% CI, 1.34-1.54]), return of spontaneous circulation on emergency department arrival (range, 9.0%-57.1%; unadjusted MOR, 1.53 [95% CI, 1.43-1.65]), and favorable functional outcome (range, 0%-20.4%; unadjusted MOR, 1.54 [95% CI, 1.40-1.73]).[1]

 

MOR = Median Odds Ratio – how many times more likely is something to happen.

What is most commonly measured is what matters the least – ROSC (Return Of Spontaneous Circulation). Did we get a pulse back, for even the briefest period of time, regardless of outcomes that matter.

What matters? Does the person wake up and have the ability to function as they did before the cardiac arrest.

Those who justify focusing on ROSC claim that, If we don’t get a pulse back, nothing else matters, but that is the kind of excuse used by frauds. How we get a pulse back does matter. The evidence makes that conclusion irrefutable, but there will always be those who do not accept that they are causing harm. They will make excuses for the harm they are causing. Getting ROSC helps them to feel that they are not causing harm. ROSC encourages us to give drugs like epinephrine, which have been demonstrated to not improve any survival that matters.

The means of obtaining ROSC can be compared to the means of doing anything that requires finesse. Sure, it feels good to try to force something. Sure, you can claim that forcing something is the most direct way to accomplish the goal.

Can the advocates of focusing on ROSC produce any valid evidence that their approach leads to improvements in outcomes that matter? No. The evidence contradicts their claims. The evidence has caused us to eliminate many of their treatments – treatments they claimed had to work because of physiology. As it turns out, they were wrong. They were wrong about their treatments and wrong about their understanding of physiology.

If you want to win money, bet that any new treatment will not improve outcomes that matter.
 

This variation persisted despite adjustment for patient-level and EMS agency–level factors known to be associated with outcomes (adjusted MOR for survival 1.56 [95% CI 1.44-1.73]; adjusted MOR for return of spontaneous circulation at emergency department arrival, 1.50 [95% CI, 1.41-1.62]; adjusted MOR for functionally favorable survival, 1.53 [95% CI, 1.37-1.78]).[1]

 

Is presence of a pulse upon arrival at the emergency department an important outcome? Only for billing purposes. The presence of a pulse justifies providing more, and more expensive, treatments. Is the presence of a pulse upon arrival at the emergency department a goal worth trying for? As with ROSC, only if it does not cause us to harm patients to obtain this goal, which is just something that is documented, because it is a point of transfer of patient care.
 

After restricting analysis to those who survived more than 60 minutes after hospital arrival and including hospital treatment characteristics, the variation persisted (adjusted MOR for survival, 1.49 [95% CI, 1.36-1.69]; adjusted MOR for functionally favorable survival, 1.34 [95% CI, 1.20-1.59]).[1]

 

There is a lot of variability.

What did they find?
 


 

Most of the people in EMS, who claim to be doing what is best for their patients, are making things worse.
 

69% means that there are two EMS agencies producing bad outcomes for every EMS agency producing good outcomes.

Correction – The text crossed out is not accurate. I should have thought that through a bit better before I posted it. My caption for Table 1 is accurate. However, what I should have written afterward is –

The worse half of EMS agencies are only producing half as many good outcomes as the better half of EMS agencies.

We are bad at resuscitation and those doing the most resuscitating are doing the least good.

Why do so many of us refuse to improve our standards?

What is more important than the outcomes for our patients?
 

Why are we so overwhelmingly bad at resuscitation?
 

What are the authors’ conclusions?
 

This study has implications for improvement of OHCA management. First, the analysis indicates that the highest-performing EMS agencies had more layperson interventions and more EMS personnel on scene.[1]

 

They do not conclude that we need more doctors, more nurses, or more paramedics responding to cardiac arrest.
 

Second, our findings justify further efforts to identify potentially modifiable factors that may explain this residual variation in outcomes and could be targets of public health interventions.[1]

 

We need to figure out what we are doing, because the people telling us that they know that we need intubation are lying.

We need to figure out what we are doing, because the people telling us that they know that we need epinephrine are lying.

We need to figure out what we are doing, because the people telling us that they know that we need amiodarone are lying.

We need to figure out what we are doing, because the people telling us that they know that we need ________ are lying.

How dare I call them liars?

Let them produce valid evidence that the interventions they claim are necessary actually do improve outcomes that matter.

Have them stop making excuses and start producing results.

I dare them.

The only time we have made significant improvements in outcomes have been when we emphasized chest compressions, especially bystander chest compressions, and when we emphasized bystander defibrillation.

It is time to start requiring evidence of benefit for everything we do to patients.

Our patients are too important to be subjected to witchcraft, based on opinions and an absence of research.

There is plenty of valid evidence that using only chest compressions improves outcomes.

A Randomized Trial of Epinephrine in Out-of-Hospital Cardiac Arrest – Part I

 
Also to be posted on ResearchBlogging.org when they relaunch the site.

The results are in from the only completed Adrenaline (Epinephrine in non-Commonwealth countries) vs. Placebo for Cardiac Arrest study.
 


 

Even I overestimated the possibility of benefit of epinephrine.

I had hoped that there would be some evidence to help identify patients who might benefit from epinephrine, but that is not the case.

PARAMEDIC2 (Prehospital Assessment of the Role of Adrenaline: Measuring the Effectiveness of Drug Administration in Cardiac Arrest) compared adrenaline (epinephrine) with placebo in a “randomized, double-blind trial involving 8014 patients with out-of-hospital cardiac arrest”.

More people survived for at least 30 days with epinephrine, which is entirely expected. There has not been any controversy about whether giving epinephrine produces pulses more often than not giving epinephrine. As with amiodarone (Nexterone and Pacerone), the question has been whether we are just filling the ICUs and nursing home beds with comatose patients.
 

There was no statistical evidence of a modification in treatment effect by such factors as the patient’s age, whether the cardiac arrest was witnessed, whether CPR was performed by a bystander, initial cardiac rhythm, or response time or time to trial-agent administration (Fig. S7 in the Supplementary Appendix). [1]

 

The secondary outcome is what everyone has been much more interested in – what are the neurological outcomes with adrenaline vs. without adrenaline?

The best outcome was no detectable neurological impairment.
 

the benefits of epinephrine that were identified in our trial are small, since they would result in 1 extra survivor for every 112 patients treated. This number is less than the minimal clinically important difference that has been defined in previous studies.29,30 Among the survivors, almost twice the number in the epinephrine group as in the placebo group had severe neurologic impairment.

Our work with patients and the public before starting the trial (as summarized in the Supplementary Appendix) identified survival with a favorable neurologic outcome to be a higher priority than survival alone. [1]

 


Click on the image to make it larger.
 

Are there some patients who will do better with epinephrine than without?

Maybe (I would have written probably, before these results), but we still do not know how to identify those patients.

Is titrating tiny amounts of epinephrine, to observe for response, reasonable? What response would we be looking for? Wat do we do if we observe that response? We have been using epinephrine for over half a century and we still don’t know when to use it, how much to use, or how to identify the patients who might benefit.

I will write more about these results later

We now have evidence that, as with amiodarone, we should only be using epinephrine as part of well controlled trials.

Happy Friday the 13th – Only Ten Days to the Next End of the World

 
I hope that you have been out enjoying the day as much as I have. You have two extra days to procrastinate, before taxes are due this year on the 17th.

The End of the World isn’t coming until after taxes are due, so don’t let that discourage you.

What will we do when the brimstone hits the fan, this time?[1]
 


 

The same thing we did last time, and the time before that, and the time before that, and . . . .

We will listen to more excuses.

There have been many Ends of the World, but nobody seems to have noticed.

We need to demand better Ends of the World.

Why do prophets get away with such low standards?

We should notice something.

Maybe I should sell End of the World protection amulets.
 

This survived the last End of the world, and the one before that, and the one before that, and . . .

Clearly, this is extremely effective and reusable.

Act now.

Your supply of gullibility may be limited.

Have a Slow, Quiet Friday the Thirteenth

Also to be posted on ResearchBlogging.org when they relaunch the site.
 

 

Superstitious appears to be common among medical people, so this may be seen as offensive. If you doubt me, comment that it is slow or quiet and see how many respond negatively, while they do not receive any criticism for their superstition-based complaints. Rather, people will make excuses for coddling the superstitions of those who are entrusted with the lives of patients.

The evidence does not support their superstitions.

One study did appear to show that women die in motor vehicle collisions more often on Friday the 13th, but that appears to be due to a lack of understanding of statistics by many who cite the article.
 

An additional factor is anxiolytic medication, used by significantly more women than men in Finland (7), which has been reported to reduce attention span and worsen driving performance (8). . . . Why this phenomenon exists in women but not in men remains unknown, but perhaps the twice-as-high prevalence of neurotic disorders and anxiety symptoms in women (7) makes them more susceptible to superstition and worsening of driving performance.[1]

 

The author suspects that those people with conditions that could be diagnosed as neuroses or anxiety disorders may be disproportionately affected by superstition.

In other words, superstition is not an external force affecting you. You are doing it to yourself.

The sample size was national, but still small, and was not able to adjust for many possible confounding variables, so the study would need to be replicated using a much larger data base to be useful.

In other superstition news – the next apocalypse, in a long line of predicted apocalypses, is going to be this Sunday – the 15 of October, 2017, according to David Meade. Meade twice previously predicted that a magical planet would hit the Earth and kill us all. This time he claims that his calculations are accurate, because that was the problem with his previous calculations – inaccuracy, not that they were a superstition deserving of derision.

If you are superstitious, and feel that your neuroses/anxieties will cause you to harm others, or yourself, you may want to stay home today and Sunday – perhaps even until you are capable of grasping reality.

Of course, we would never base treatment on superstition in medicine.

Amiodarone is the go to antiarrhythmic drug for cardiac arrest and ventricular tachycardia, but there are much safer much more effective drugs available. We have our own prophets misrepresenting research results to make it seem that using amiodarone for these is a good idea. The research says these preachers are wrong. The next guidelines will probably promote the superstition and reject the science.[2],[3]

Ventilation during cardiac arrest has been shown to be a good idea only for patients who arrested for respiratory reasons. We do a great job of identifying these patients. We have our own prophets misrepresenting research results to make it seem that providing ventilations for these is a good idea. The research says these preachers are wrong. The next guidelines will probably promote the superstition and reject the science.[4]

Medicine is full of superstition and superstitious people.

Why?

Too many of us believe the lie that, I’ve seen it work.

I have also written about the superstition of Friday the 13th here –

Comment on Irresponsibility and Intubation – The EMS Standard Of Care

 

I wrote about the petition to protect paramedic incompetence in Irresponsibility and Intubation – The EMS Standard Of Care

Nathan Boone responded with the following comment
 

You’re forgetting about the rural medic out there.

 

No. I am not.

Are you suggesting that bad airway management for a longer period of time is less harmful than bad airway management for a shorter period of time?
 


 

Where we are with our patients for more then a hour, not 5 mintues.

 

The harm from incompetent airway management does not depend on distance from the hospital. Intubation even kills patients in the hospital.

You may believe that the efficacy of voodoo is directly related to the distance from the hospital, but it appears to be only your belief that increases.

Voodoo does not work, regardless of the distance from the hospital.

If the paramedic cannot manage an airway, the paramedic should not be permitted to intubate.
 

Sometimes air- craft isn’t available if its raining or on another call.. You want us to use a bvm and take chance of filling the patients stomic up for over a hour.. Yes we can be extremely careful and do everything in our power not to fill the stomic but there’s some patients out there who have difficult airways where bagging can be extremely difficult and or impossible.

 

Give incompetent paramedics dangerous tools to try to manage difficult airways because of distance? Wouldn’t it be better to try to make them competent – or to limit intubation to competent paramedics?

Intubation and BVM (Bag Valve Mask) are not the only forms of ventilation.
 

Rsi does save patients in rural areas, we need intubations..

 

Maybe. Maybe not. Maybe RSI kills more patients than it saves.

Actually, what I mean to write is, Maybe paramedics using RSI kill more patients than they save.

If you want to claim otherwise, prove it with high-quality research.

Unless you can provide high-quality research, your plastic airway religion is just another alt-med scam.

If your patients are important, then you need to demand that we find out what is best for the patients.
 

Do I believe that Rsi is risky and their is some medics out there who would rather make the patient more hypoxic then before until they give up and go to a secondary airway..absolutely.. But to take it away from Rural Medics when we can have anything to burn patients to anaphylactic reactions and to take our ONLY definitive airway;away from us..

 

You seem to think that RSI (Rapid Sequence Induction of anesthesia) becomes less risky the farther you are from the hospital.

Why?

Incompetence for a longer period will be expected to cause more harm.

Sometimes the incompetence of the paramedic doesn’t kill the patient.
 

Trauma patients were significantly more likely to have misplaced ETTs than medical patients (37% versus 14%, P<.01). With one exception, all the patients found to have esophageal tube placement exhibited the absence of ETCO2 on patient arrival. In the exception, the patient was found to be breathing spontaneously despite a nasotracheal tube placed in the esophagus.[1]

 

The patient clearly did not need intubation.

As with the crash of Trooper 2 in Maryland, the survival of the patient for hours in the woods, in the rain, following the helicopter crash that killed all of the other healthy people on board, was clear evidence that there was no reason to send this patient to the trauma center by air.

The same argument was provided by people, including Dr. Thomas Scalea, the head of Shock Trauma – If you don’t let us have our toys, people will die![2]

The rate of helicopter transport of trauma patients was dramatically cut.

That was almost a decade ago and we are still waiting for the dead bodies.

I expect that the same failure of prophesy will occur, when incompetent paramedics are prevented from intubating.

I expect that the fatality rate will decrease, when incompetent paramedics are prevented from intubating.
 

I think you’re out of your mind.

 

Many religious fanatics do.
 

In the city, I can maybe defend you. But the studies need to be done out in the sticks as well. I believe that we should have to go outpatient surgery every year or 2 or have number set of how many we need in that time period successfully to keep our skills sharp..

 

Every year or two?

WTF?

You don’t want to be taken seriously, do you?

This is something that requires a lot of skill and practice, so I get just a tiny bit, every other year. Trust me with your life.
 

After a Rsi and I have no one in the back but myself for over an hour.., I can place the patient on a vent and care for my patient. If RSI is taken away. I loose the capability to monitor my patient, and would be more focused on bagging my patient, or making sure the secondary away isn’t failing and I’m filling the stomic on the vent, because it can happen.

 

It is just a staffing issue.

That is different.

Competence isn’t needed when you are in the back by yourself.

Why are you opposed to competence?

Where is a single reasonable argument that intubation improves outcomes?

Where is a single reasonable argument that rural paramedics have an intubation success rate that is above 95%?

Even 95% means that some of your patients don’t end up with a properly placed endotracheal tube. What do you think happens to them?

Does your EMS agency have a better than 95% intubation success rate?

If you can’t manage at least 95%, why do you believe you can manage intubation?

Is each intubation on video, or do they just believe whatever you tell them?

If you want to be taken seriously, these are just some of the essential points to address.
 

This is not a new topic. You might also read the series below:

Acute coronary syndrome on Friday the 13th: a case for re-organising services?

ResearchBlogging.orgAcute coronary syndrome on Friday the 13th - a case for re-organising services 1
 
There has been a bunch of research on the likelihood of bad things happening on Friday the 13th. These researchers thought that the big problem with all of the available research is that the populations studied have been too small. The authors took information on over 56,000 patients with acute coronary syndromes, broke them down into 217 day/date combinations (Friday the 1st, Saturday the 1st, . . . ,Wednesday the 31st, Thursday the 31st), and compared the outcomes of those 216 groups with their Friday the 13th group.

Cut to the conclusion –
 

Conclusion: On most days, there was no difference in the 13-year mortality rate for patients admitted with their first ACS from that for “unlucky” Friday the 13th. However, patients admitted on five day/number combinations were 20-30% more likely to survive at 13 years. These findings could be explained by subgroup analysis inflation of the type I error, although supernatural causes merit further investigation.[1]

 

No. Supernatural causes do not merit further investigation, at least, not based on anything in this paper.

The authors used Friday the 13th as their normal date for comparison with every other date, but the outcomes from Friday the 13th are not the true statistical mean. The outcomes on Friday the 13th were just chosen because of the superstition being investigated. Friday the 13th is so close to the statistical mean that this mistake is easy to make.
 

Surprisingly, however, we also identified five potentially “lucky” days on which mortality rates were significantly lower, by 20-30%.[1]

 

When analyzing 217 samples, it is not surprising that some of the data deviate from average by an amount that is expected to produce no more than one significant deviation out of every twenty comparisons. The authors had over 200 comparisons, so we should not have been surprised by up to 11 day/date combinations with p values of less than 0.05. There were only 5. Should anyone go looking for supernatural explanations for statistically normal outcomes?

While Friday the 13th was not the statistical mean, it was very close. Look at the five potentially “lucky” days and how close the ranges are to 1.00. If the range crosses (includes) 1.00, the results are not statistically significant according to the prospectively determined criteria of the authors. Crossing 1.00 is just another way of expressing P <0.05. Sunday the 1st and Monday the 29th each produced outcomes 29% worse than Friday the 13th. Saturday the 31st produced outcomes that were 36% worse. If we compared these with the actual statistical mean, Monday the 29th and Saturday the 31st become significantly “unlucky” using a p value of less than 0.05 and all of the significantly “lucky” days become insignificant.

As we should expect, the most extreme benefit and harm both fall on the 31st. Only 7/12 (58.3%) of months have 31 days, so these days have much smaller sample sizes. With smaller samples, the appearance of deviance is expected to be greater. The actual deviation is less important, because the sample size is smaller.

Friday the 13th is only slightly different from the statistical mean, using the data in this paper, which may be the largest examination of a possible Friday the 13th effect.

Once again, the biggest problem with Friday the 13th is that we end up listening to people promoting superstition.

2016 – Amiodarone is Useless, but Ketamine Gets Another Use

amiodarone-edit-1
 

I didn’t write a lot in 2016, but 2016 may have been the year we put the final nail in the coffin of amiodarone. Two major studies were published and both were very negative for amiodarone.

If we give enough amiodarone to have an effect on ventricular tachycardia, it will usually be a negative effect.[1]

Only 38% of ventricular tachycardia patients improved after amiodarone, but 48% had major adverse cardiac events after amiodarone.

There are better drugs, including adenosine, sotalol, procainamide, and ketamine for ventricular tachycardia. Sedation and cardioversion is a much better choice. Cardioversion is actually expected after giving amiodarone.

For cardiac arrest, amiodarone is not any better than placebo or lidocaine. What ever happened to the study of amiodarone that was showing such wonderful results over a decade ago? It still hasn’t been published, so it is reasonable to conclude that the results were negative for amiodarone. It is time to make room in the drug bag for something that works.[2],[3]

On the other hand, now that we have improved the quality of CPR by focusing on compressions, rather than drugs, more patients are waking up while chest compressions are being performed, but without spontaneous circulation, so ketamine has another promising use. And ketamine is still good for sedation for intubation, for getting a patient to tolerate high flow oxygen, for agitated delirium, for pain management, . . . .[4],[5]

Masimo’s RAD 57 still doesn’t have any evidence that it works well on real patients.[6]

When intubating, breathe. Breathing is good. Isn’t inability to breathe the reason for intubation?[7]
