| ST. Louis Nurse Leads Rare, Prospective Study |
by Paul Bernstein, Ph.D.Nurse Janet Schwaninger, coordinator of cardiology care at Barnes-Jewish Hospital, a teaching venue of the Washington University medical school (St. Louis, Missouri), this summer saw her three year study of near-death experiencers published in the Journal of Near-Death Studies. Her research is only the third prospective* study of cardiac-arrest neardeath experiencers published in the US, and the fifth ever in the world. Vital Signs is delighted to have had the opportunity to interview Nurse Schwaninger, to gain from her an inside view of the practical rigors of designing, conducting, and publishing such valuable research.
VS: What started you in this work? *Interviewing all revived patients in a hospital unit, before knowing which ones have had an NDE.
I was very moved by how significantly this physician’s life changed the
year following his experience: he became a happier person, he began
enjoying his life, he made significant changes in his family and
personal life, and in his medical practice. Several times he came back
to us, wanting to discuss the experience. At that time, though I had
heard of the near-death experience I really had not read much about it.
So this event stimulated me to go to the library and do a computer
search, trying to find out all I could about the experience, and to
share that with him.
what I was trying to do. For example, one physician in the hospital who’d heard that I’d sent this proposal to the Human Studies Committee said, “Well, I guess you’re not going to hurt anybody.” But the official committee from the very beginning took the research very seriously, and before long gave me total approval to proceed. They were pleased that I had studied all the existing literature in the field; they definitely felt that it would be a worthwhile study. I think it also may have helped that Dr. Weiss and I are wellknown at the hospital; we had already worked there for 12 years, and we took care of a large number of patients. We’re on hospital rounds every day and also have contact with a wide variety of the staff.
VS: So you were already known and credible, and when you proposed something
that stretched your colleagues’ beliefs,
they thought, “Well, we’ll keep listening.” So once I started the study, I was surprised at how much interest a variety of medical professionals had within the hospital and the university. As time went on, some personnel would ask, “How’s your study going, how many patients do you have? Tell me.” These people then told other professionals, and a number of their patients contacted me directly. VS: The three other co-authors of your study—how did each of them get involved?
Dr. Alan Weiss and I had been working together in cardiology for many years, and he was very supportive of the study from the beginning. He came with me on a number of the interviews and helped organize the data.
And Dr. Kenneth Schechtman was recommended to me as an expert
statistician by Dr. Eisenberg. Dr. Schechtman is associate professor of
biostatistics at Washington University.
VS: What kinds of practical problems did you have to solve in order to accomplish the study?
We tracked every single code in the hospital for three years—I had it worked out so that every head nurse on every floor would report through the administrative office and record in a logbook at the end of every shift each person who arrested. I also carried a code beeper for those three years, twenty-four hours a day, so I would be alerted to every potential cardiac arrest in the hospital. The only unit that I had trouble with was the surgical intensive care unit, because their codes did not go through the central paging system. After a number of unsuccessful tries at tracking their codes, we ended up excluding that unit —which was probably good for the study, because then we didn’t have to deal with patients who’d been given anesthesia, with all the issues of memory compromise that involves. So over three years we tracked a total of 273 codes. I was doing almost all the interviewing and reviewing of medical records, at the end of working a 9- or 10-hour day.
JS: Well, actually, I didn’t. I kind of took it on myself, and felt that once I’d gotten the support of every head nurse and unit to help me track all the codes, that was about as much as I could ask for. I did consider other types of patients as potential research subjects— those who were hypotensive [very low blood pressure], and those who had respiratory arrest—because they too could very well have had near-death experiences. But in order to make the study as scientifically rigorous as possible, I had to confine it and look only at the near-death experiences of people who had true cardiac arrest. I didn’t have the time nor the manpower to include the others. Additionally, lots of people started sending me their neardeath experiences when they heard about the project through the media. Many local TV channels had called me for an interview, and several stations then sent their tapes to the national networks. That’s when I got a little sidetracked dealing with the retrospective* group of individuals. I went back to the Human Studies Committee and asked if I could send this retrospective group the same follow-up form that I had sent to the prospective patients. They approved it. Some of those people had experiences dating back into the 1930s, yet they were still able to give the same kind of clarity as the recent group. I spent a lot of time analyzing their experiences, and comparing them with my prospective group.But when it came to writing up the paper for submission to the Journal of Near-Death Studies, its Editor, Dr. Greyson, urged me to set aside the retrospective cases and report them separately. I have a lot of data for 40 patients in that retrospective group. But I understood what Dr. Greyson and the other editor said, that they didn’t want to muddy the waters by mixing that retrospective group in with the prospective group, and I agreed with him. Unfortunately, I felt like those people had so much to say; it was hard to exclude them.
VS: You spent three years gathering the data?
VS: Why did it take so much longer?
VS: And since 1994, has it been—or could it still be—feasible for
you, or perhaps for some colleagues or graduate students, to see what
the longerterm consequences have been for those people?
I could also go back to the patients’ medical records, to look at what their blood gasses were, etc. I know in one British study, Dr. Parnia and his colleagues looked at that and didn’t see any differences between the NDEr and non-NDEr groups in carbon dioxide levels; they were within the normal range for both groups. The NDErs even had higher oxygen levels than the non-NDErs, suggesting that these experiences don’t happen just when oxygen levels are low.The thing that I find so interesting is that it makes you wonder if consciousness may continue after the brain has stopped functioning. I wish an MRI could have been done during the arrest. I know that EEGs have been done on patients during cardiac arrest, as the Dutch team under Dr. van Lommel reported. They stated that patients were flat-lined; there was no EEG response. Yet so many times when talking with these NDE patients I saw how lucid their thought processes had been during the time of their cardiac arrest, how structured they were; there was an element of intelligence and reasoning going on there. Normally you would expect that there would be no memory at all from such periods of “unconsciousness”. A lot of patients will tell you after a traumatic event, “I remember going into it, but I don’t remember anything from the next several days.” What’s so amazing about these neardeath patients is that they obviously remember well enough to tell us what they experienced, from a time when you wouldn’t think that they’d be having memory formation, or any kind of mental experience.
VS: Yes. If the body’s in crisis with cardiac arrest, you’d think
that if there’s any mental activity at all it would have to do with
fear, panic, or trauma.
A lot of the patients tell me that during the experience there was a functioning of their consciousness beyond the timespace boundary. 82% of our subjects told me there was no sense of time or space. That was very consistent: ‘I was aware.’ ‘I was conscious, yet I was definitely not in any kind of time-space framework’—which was very interesting to me. Basically they were telling me that their awareness was present within the moment. And they perceive this moment as being eternal, also. And then they all said there was some kind of survival of their soul or consciousness beyond the physical. They kept telling me, “Well, you’re not going to be able to explain this in psychological or physiological terms.” So you wonder if this doesn’t shed some light on consciousness working independently of the brain itself. Of course there very well could be an area of the brain that helps us make that transition, or that’s involved in the separation of consciousness from the physical organism. Or a particular awareness comes about when certain areas of the brain are not functioning, having possibly been shut down as a consequence of the cardiac arrest.
VS: Was the process of analyzing and writing up the data at all problematic?
But I have to say that the version we submitted to those other journals was not nearly as refined as it turned out to be after I incorporated the suggestions of Dr. Greyson and the other reviewers. They’re the ones who really fine-tuned the paper for me and brought out some of the important material that I had gathered but hadn’t included in my original draft. For example, the experiential and physical changes that are in the last two tables. And the specifics on the code data. Both made the article better, but I had not had them in the original draft I’d sent to JAMA, the American Journal of Psychiatry and the American Journal of Psychology. So as it turned out, it was published exactly where I’d wanted it to be. Because Dr. Greyson had been behind me and supportive from the very beginning, and I really wanted him to have this study to publish. But I have to tell you, one interesting thing about the study is that from the beginning it had a mind and a time of its own. No matter how much I tried to speed it up or to get it done, there was always something that just kept it right on its own time. People said, “Why are you doing this? Why are you putting in so many hours—and years—of your time?” And I couldn’t really tell them, other than it was just something I knew was very important, that was meant to be done. Re-organizing the data and fine-tuning the statistical operations went on year after year. I felt, this will be done when it’s meant to be done; this will be published when it’s meant to be. It was interesting because recently studies began to be published on prayer in coronary units and alternative medical therapies, so it really was good timing. I think it meant more to the public that it came out now than if it would have come out perhaps several years ago.When I think of how long it took to complete the paper, I also recall the obstacles that I had to overcome. But never once did I say that I was going to give up. No matter how gloomy it looked, no matter how difficult it was, I just felt that I needed to do this. The study did not receive any funding, no one received any payment, no compensation—it just wasn’t about that.
VS: Have you seen that there has been progress at Barnes Hospital
because of this? And even if there’s been progress, are there still
obstacles by people who should know better but still refuse to pay
attention?
So there’s this whole new awareness of how we treat patients when we think they’re unconscious. That’s one awareness. Now medical professionals ask how can they intelligently discuss such experiences when they have a patient that tells them they’ve had one. They now have avenues for providing the patient with support. There is an IANDS support group in the St. Louis area. I had a lot of interest from the psychiatrists and psychologists. One who was particularly responsive said, “I would be very happy to see any of your patients who need extra psychological support. I’ll be happy to take on those patients.” So I was able to establish a psychiatric and psychology referral involving a number of support systems within Barnes Hospital. It increased awareness. Most people didn’t even know what a near-death experience was when the study began. Now most medical professionals know what they are, and their significance. They all use their knowledge in the management of patients now, from the coronary care unit to the neurological intensive care unit.
VS: Has any of this experience become part of anyone’s teaching inside the University’s medical school?
When the study was published this summer, Washington University and Barnes Hospital were so supportive. The University put out press releases, both in the print media and in radio across the country. And I’ve been contacted by local TV stations wanting me to appear on more shows. The international issue of the Miami Herald put out a story on our study. From that I got responses from scientists and other individuals in Costa Rica, Ecuador and Peru. People were so pleased that we had done the study, and thought it was significant, expressing their interest, a lot of physicians and medical professionals just contacting me, being in support, and sharing their experiences or those of their patients or their personal loved ones.VS: If somebody fairly new in nursing or cardiology, perhaps even a medical or nursing student, were leaning towards doing such a prospective study, what kind of advice would you give them? JS: Not to give up! Because it’s so significant, and there’s something so important that’s being said by the patients, significant information that’s being given to humanity. And not just the message is important, but how we see that such a brief experience can so profoundly change a person’s life. How important it is to recognize and address these experiences in the management and care of patients. Paul Bernstein is on the editorial team of Vital Signs.
