Complexity Intervention Units Past And Present

Here’s another blast from the past about Complexity Intervention Units (CIUs) or what used to be called Medical-Psychiatry Units. I co-staffed one for 17 years at Iowa Health Care, the organization formerly known as Prince. No wait, that used to be called the University of Iowa Hospitals & Clinics. They’re rebranding.

I was looking up CIU on the web. It’s a common search term now, so Roger Kathol, the guy who built the CIU at Iowa Health Care, was right.

On the other hand, I was also puzzled when the results showed that a hospital in Wisconsin has what’s called a brand new CIU-only it’s not a psychiatric unit.

I thought a CIU was, by definition, a combined specialty unit, with facilities for acute care of both psychiatric and medical problems. But Froedtert Medical Center in Milwaukee has a new CIU and yet says: “The department is licensed as a Medical Unit – not a Psychiatric Unit.”

In fact, Medical College of Wisconsin says essentially the same thing about the CIU: “Please note that the CIU is not an inpatient psychiatric unit, but rather a facility dedicated to integrated care.”

OK, so I probably missed the memo about what a CIU is nowadays. It’s tough to find out how many CIUs are in operation in the U.S., maybe partly depending on how you define it and who you ask. Anyway, this is what I wrote about them 12 years ago:

The Complexity Intervention Unit for Managing Delirious Patients

Is there such a thing as a specialized unit in the general hospital where patients with delirium could be treated, where both their medical and behavioral issues could be managed by nurses and doctors specifically trained for that purpose? It turns out there is. Although they are usually called medical-psychiatry units, an internationally recognized expert about designing and staffing these specialized wards, Dr. Roger Kathol, M.D., F.A.P.M., would prefer to call them “Complexity Intervention Units” (CIUs). It’s a mouthful, but it’s a better description of the interaction between physical and psychiatric illness, along with social and health care system challenges typically managed in these units.

We’ve had one at Iowa since Dr. Kathol started it in 1986. It was one of the first such units built and now that it has been redesigned, updated, and beds with cardiac monitors added, it’s arguably the only unit of its kind in the country. The CIU allows us to provide both intensive medical and psychiatric interventions that would be all but impossible to deliver on general medical floors with psychiatric consultation. The essential features of the CIU include:

  1. Both medical and psychiatric safety features in the physical structure.
  2. Consolidated general-medical and psychiatric policies and procedures.
  3. Location in the general hospital under medical bed licensure and with psychiatric bed attributes.
  4. Moderate-to-high medical and psychiatric acuity capability.
  5. Physicians from combined residencies general medicine and psychiatry co-attending model with consistent communication and coordination of medical and psychiatric care.
  6. Nurses and other staff cross-trained in medical and psychiatric assessments and interventions.

The unit is used to optimize management of a variety of patients with both medical and psychiatric diagnoses. The focus is on providing care for the 2%-4% of patients admitted to general hospitals who are too complicated to manage on either psychiatric or medical units. And it’s an excellent teaching resource for helping new doctors learn about the inevitable interaction between medical and psychiatric disorders in an environment that fosters both/and thinking. Trainees learn that delirium mimics nearly every other psychiatric disorder and how to distinguish delirium from primary psychiatric illness.

I co-staff the unit with a colleague from internal medicine when I’m not staffing the general hospital consultation service. That helps me blend the perspectives of each role. Often, acting in the role of psychiatric consultant, I can assist the generalist in managing patients with less complicated delirium without transferring them to the CIU. And for those whose behavioral challenges would be overwhelming for nurses and physicians on open medical units, it’s helpful to have the CIU option available.

While the CIU is a great resource for managing delirious patients, they are expensive to build and generally have a limited number of beds. So it’s still important to continue work on developing practical delirium early detection and prevention programs in every hospital.

Plate!

I was listening to the Big Mo Blues Show last night on KCCK radio, 88.3 on your FM dial. I didn’t hear him mention his favorite cook, May Ree. She cooks hand-battered catfish; it’s better because it’s battered. Often, he’ll add a little to the legend, like where you can find May Ree’s establishment where you can buy her hand-battered catfish, which is filled with nitrates, cooked to perfection with manic delight, and which you can pair with any one of three flavors of moonshine, including the famous Classic Clear.

I don’t know whether Classic Clear has fruity, nutty, or extraterrestrial notes. You’ll have to try to find her joint, which is somewhere at the intersection of a highway and a street the name of which I can never recall. The story gets a new variation every now and then. May Ree has many facets to her character.

May Ree actually reminds me of the head cook at Huston-Tillotson College (now Huston-Tillotson University) in Austin, Texas. Back in the 1970s, I was a student there for a while. The head cook in the college cafeteria was Miss Mack. I don’t think you could say she cooked anything with manic delight. In fact, some of us were regular visitors who rushed with manic delight to Church’s Chicken because the H-TC cafeteria didn’t always serve what you’d call top of the line fare.

I guess Church’s want to call themselves Church’s Texas Chicken these days, mainly because they got the business started in San Antonio. Back in the day, Church’s Texas Chicken was a five-minute walk from the college. I checked a map recently, and now there isn’t a joint within an hour’s walk.

Anyway, I was a fairly frequent customer to Church’s Texas Chicken. You didn’t have a whole lot of choices about what to select. In fact, I don’t recall that there was a selection, per se. What you saw was what you got.

Sometimes, certain students were pretty frank about what they thought of Miss Mack’s cooking. One day, a guy who was fed up, in a manner of speaking, of course, held up his plate so that it was vertical, and weirdly, none of the food slid off. It just stuck there, like it was sort of a sculpture of a meal.

And then he called out loudly to everyone else in the cafeteria (not that there were many people there) as if he were offering to give to anyone there:

“Plate!” (no takers). “Plate!” (still no takers). “Plate!” (students just ignored him, but started making funny looks at their own plates).

I don’t remember what happened, but I think he just left his plate on the table and departed. I doubt Miss Mack was there. I was ambivalent about the whole deal. I liked Miss Mack, as did a lot of other students. She was kind and always had a bright smile for us.

Maybe he made a run to Church’s Texas Chicken. Funny, I didn’t see him there.

Who Gets the Credit?

When I think about peak moments, I remember this guy back in junior high school who decided to try to break the Guinness Book of World Records for skipping rope. I don’t remember his name but the school principal and his teachers all agreed to let him do it during class hours. They marked out a little space for him in our home room. He was at it all day. And he was never alone because there was always a class in the room throughout the day. We didn’t get much work done because we couldn’t keep our eyes off him. It was mesmerizing. The longer he jumped, the more we hoped. We were very careful about how we encouraged him. We didn’t want to distract him and make him miss a jump. And so we watched him with hope in our hearts. It was palpable.  As he neared the goal, we were all crowded around him, teachers and students cheering. He was exhausted and could barely swing the rope over his head and lift his knees. When he made the time mark, we lifted him high above our heads and you could have heard us yelling our fool heads off for miles. Time stood still. He was a hero and we were his adoring fans. It didn’t occur to us to be jealous. His achievement belonged to all of us.

In 2016, an article was published in Psychosomatics, the official journal of the Academy of Consultation-Liaison Psychiatry (ACLP), which detailed the success of a quality improvement program to co-manage patients with co-morbid medical and psychiatric disorders in the general hospital (Muskin PR, Skomorowsky A, Shah RN. Co-managed Care for Medical Inpatients, C-L vs C/L Psychiatry. Psychosomatics. 2016 May-Jun;57(3):258-63. doi: 10.1016/j.psym.2016.02.001. Epub 2016 Feb 2. PMID: 27039157.). This entailed making a psychiatrist an embedded member of the general medicine team in the hospital who actively comanaged medical patients.

It was so successful that it reduced length-of-stay and lost days to the hospital by a significant margin. It also supported the idea of liaison psychiatry. Dr. Muskin visited the University of Iowa Hospital Department of Psychiatry and gave a Grand Rounds presentation about the project. It also was funded in large part by a philanthropic donation. Who gets the credit? It doesn’t matter because the achievement belonged to all who participated.

“It is amazing what you can accomplish if you do not care who gets the credit”-Harry Truman, Kansas Legislature member John Solbach, Ronald Reagan, Charles E. Montague, Benjamin Jowett, a  Jesuit Father, a wise man, Edward T. Cook, Edward Everett Hale, a Jesuit Priest named Father Strickland.

A Look Back at Intravenous Haloperidol for Delirium

I found one of my old blog posts about using intravenous infusions of haloperidol for delirium in the intensive care unit. The bottom line is it that it probably should not be used, in my opinion. This is sort of a follow up on my Christmas Eve blog post in which I mention talking to ICU personnel about using IV haldol for delirium. I’ve edited out a portion of the old post.

Notes on Pharmacology for the Treatment and Prevention of Delirium: IV Haldol Infusions

“I ran across the Canadian Coalition for Seniors’ Mental Health guidelines for the management of delirium in elder adults. You can access them for free at the at this link, CCSMH – Canadian Coalition for Seniors’ Mental Health. I was a bit surprised to read the following recommendation:

For those who require multiple bolus doses of antipsychotic medications, continuous intravenous infusion of antipsychotic medication may be useful.

Note: I read this in 2011. I’ve rechecked the website of CCSMH, which shows the same recommendation when I reviewed it on December 27, 2023.

The recipe for continuous infusion of haloperidol was in a paper by Riker and I thought it was of historical interest[1]. Essentially, if the delirious patient had not responded to 8 consecutive 10mg bolus injections of haloperidol, you asked the intensivists to start a haloperidol drip at 10mg an hour. It usually didn’t work and despite the puzzling tendency for experts to claim that extrapyramidal side effects (EPSE) such as dystonias, parkinsionism, and akathisia occur at a lower rate when haloperidol is infused intravenously, the dissenting opinion from experienced psychiatric consultants including me is—if you do this enough times you’ll see EPSE. I’ve witnessed everything from trismus to opisthotonos, on one occasion all in one patient as I stood there and watched him over minutes while the intravenous (IV) haloperidol was infusing.

The idea that IV haloperidol infusions seems to stem in part from a 1987 paper by Menza[2]. There were only 10 patients total in that study.

My comments: I remember a presentation at an Academy of Consultation-Liaison (ACLP) meeting many years ago reporting that EPS (extrapyramidal side effects such as dystonia) had been reported to occur after IV administration in 67% of normal humans given a single dose, in 16-74% of adults with medical illness including burns, migraine, and Human Immunodeficiency Syndrome, and in 37% of psychiatric inpatients. EPS occured after IV administration of other dopamine blockers including the anti-nausea agent Reglan and there were at least 6 case reports of Neuroleptic Malignant Syndrome (the “ultimate EPS”) following IV administration of haloperidol.

The presenter reporter that no EPS occurred in several cases of reported very high dose IV Haloperidol, e.g., 945mg/ in 24 hours; and 1155mg in one day (from his own case report in 1995). It may have had something to do with delirium itself being a highly anticholinergic state.

There have been improvements in the management of delirium in the ICU since then. The best example I can give would be what Dr. Wesley Ely, MD has been doing for years at Vanderbilt.

Turkeys Still Doing the High Jump Over the Fence!

The wild turkeys are still doing the high jump over the fence. This time, I saw one of them jumping over the fence into the yard. So, they know how to get inside! But I couldn’t get a picture of it! I was washing the dishes at the time.

They seemed to have a somewhat easier time jumping back over the fence out of the yard. What the heck, you have to give them a little credit.

They’re only a little bit smarter than people.

Testament to Testiness on Liaison Psychiatry

The other day, I got an email message from the Academy of Consultation-Liaison Psychiatry (ACLP). It was from the Med-Psych Special Interest Group (SIG). It was an intriguing question about a paper somebody was looking for and having trouble getting it through the usual channels.

The paper was “The Liaison Psychiatrist as Busybody” by somebody named G.B. Murray and published in the Annals of Clinical Psychiatry in 1989. The person looking for the paper mentioned that there was a note from the editor that the paper was of a “controversial nature.”

I was immediately intrigued after doing a search of my own and finding out that the full note from the editor was as follows:

“Editor’s Note: We are aware of the controversial nature of this communication and invite responses from psychiatrists in practice as well in academic settings.”

Nothing is as exciting as holding something out to us and at the same time hiding it from us. Why was it unavailable through the usual channels? Nowadays “usual channels” means accessing the digital copy over the internet from the journal.

Anyway, soon enough somebody found a copy of what turned out to be Dr. George B. Murray’s presentation of the paper with the title “The Liaison Psychiatrist as Busybody” at the American Psychiatric Association (APA) meeting in 1983 in New York. It looked like it was copied from the Annals of Clinical Psychiatry journal where it was published in 1989.

The paper was one of four APA presentations (p. 76) in a symposium entitled “The Myth of Liaison Psychiatry.” The titles and presenters including Murray’s:

  1. Teaching Liaison Psychiatry as Medicine at Massachusetts General Hospital—Ned Cassem MD, Boston, MA
  2. The Liaison Psychiatrist as Busybody—George Murray MD, Boston, MA
  3. Liaison Psychiatry to the Internist—John Fetting, MD, Baltimore, MD
  4. The Hazards of “Liaison Psychiatry”—Michael G. Wise, MD, Baltimore, MD

Before I get to the paper itself, I should mention that it was my wife, Sena, who gets the credit for actually finding out that “G.B. Murray” was George B. Murray, a distinguished consultation psychiatrist at Massachusetts General Hospital.

I purposely omitted the word “liaison” from “consultation psychiatry” because he was said to have “loathed the word ‘liaison’.” This was according to the blogger (Fr Jack SJ MD) who posted an in-memoriam piece on his blog in 2013 shortly after Father George Bradshaw Murray died. He had been a Jesuit priest as well as a psychiatrist. Fr Jack SJ MD also noted that Murray ran the consult fellowship at Mass General, saying:

“George’s fellowship was unique.  He founded it in 1978 and directed it full-time until a few years ago.  By the time he retired he had trained 102 fellows mostly on his own.  His didactic methods would be frowned upon by politically-correct, mealy-mouthed, liberals of academe (bold face type by J. Amos).  His fellows thrived.  George turned us, in the words of Former Fellow Beatriz Currier, MD, “into the kind of psychiatrist I wanted to be but didn’t know how to become.”  We worked hard.  Many consults per day.  Vast amounts of reading for which he expected us to be prepared.  But he worked even harder for us.”

So, right about now, to quote one of my favorite Men in Black movies character, Agent J: “That grumpy guy’s story’s starting to come into focus a little bit here.”

I’m not going to dump big quotes from Murray’s presentation, but I can say that it’s understandable to me now why it has been described as controversial. He just sounds a little testy.

Getting back to the New York symposium, I noticed that the chairperson was Thomas P. Hackett, and the co-chair was Ned Cassem, both of Mass General, the latter also a Jesuit priest. I never met either of them, but they are legends. Hackett died in 1988 and Cassem died in 2015.

I’ve read what Hackett wrote about the difference between psychiatric consultation and psychiatric liaison:

“A distinction must be made between a consultation service and a consultation liaison service.  A consultation service is a rescue squad.  It responds to requests from other services for help with the diagnosis, treatment, or disposition of perplexing patients.  At worst, consultation work is nothing more than a brief foray into the territory of another service, usually ending with a note written in the chart outlining a plan of action.  The actual intervention is left to the consultee.  Like a volunteer firefighter, a consultant puts out the blaze and then returns home.  Like a volunteer fire brigade, a consultation service seldom has the time or manpower to set up fire prevention programs or to educate the citizenry about fireproofing.  A consultation service is the most common type of psychiatric-medical interface found in departments of psychiatry around the United States today.

A liaison service requires manpower, money, and motivation.  Sufficient personnel are necessary to allow the psychiatric consultant time to perform services other than simply interviewing troublesome patients in the area assigned.  He must be able to attend rounds, discuss patients individually with house officers, and hold teaching sessions for nurses. Liaison work is further distinguished from consultation activity in that patients are seen at the discretion of the psychiatric consultant as well as the referring physician.  Because the consultant attends social service rounds with the house officers, he is able to spot potential psychiatric problems.”—T. P. Hackett, MD.

Here’s the thing. This quote comes from Hackett’s chapter in the 1978 edition of the Massachusetts General Handbook of General Hospital Psychiatry. But I tended to gloss over what he wrote right below it:

“Once organized, a liaison service tends to expand. Most liaison services are appreciated and their contribution is recognized. Sometimes this brings tangible benefits such as space and salary from the departments being serviced. However, even under the best circumstances, the impact of a liaison effort seldom lingers after the effort is withdrawn. Lessons taught by the psychiatrist need constant reinforcement or they are forgotten by our medical colleagues. In a way, this is an advantage since it ensures a continuing need for our presence. Conversely, it disappoints the more pedagogical, because their students, while interested, fail to learn. I believe we must be philosophical. After all, our surgical colleagues do not insist that we learn to do laparotomies. They insist only that we be aware of the indications.”—T.P. Hackett, MD.

You get a clear sense of Hackett’s sense of humor as well as a practical appreciation of what can and maybe cannot be done when you try to apply liaison principles in a formal teaching approach.

So, what does Murray say about liaison psychiatry that seemed cloaked behind the term “controversial”? He starts off by admitting that his remarks will be “inflammatory” and makes no apology for it. He starts with three main statements:

  1. What all nonpsychiatric physicians appreciate, and what, in fact, works, is the medical model of consultation psychiatry.
  2. Liaison psychiatry is more myth than reality.
  3. The liaison psychiatrist is to a great extent a relatively high-status busybody.

It’s difficult to pick out excerpts from Murray’s presentation—so much of it is integral to the main message and entertaining as well that I hate to omit it. Here’s my pick anyway:

“There is a certain Olympian quality surrounding liaison psychiatrists. It is as if they will teach others the wonders of the labyrinthine biopsychosocial factors involved in patient care. The other Olympian feature centers on the so-called consultee-oriented consultation. In hearing discussions and reading the literature one can get a downwind whiff of antiphysician feeling. There are remarks made, for example, of the insensitivity of surgeons, of patient “harassment” and how little the attending physician understands this hysteric’s or sociopath’s inner dynamics. This attitude is snobbish, unhelpful, and in semistreet parlance, “chickendip.” It does not seem to bother liaison psychiatrists that there are no liaison cardiologists, liaison endocrinologists, and so forth—another clue to the vacuity of liaison psychiatry.”

He is testy and with good reason, if you define liaison in this way. His paper is uproarious. And there are lots of controversies in medicine. I’m still not sure why this one seemed hidden from public view.

I opened up the door by saying “…if you define liaison in this way.” There are other ways to convey useful information to “consultees.” For example, I had better luck talking in a casual way about what I could for a MICU medicine resident about how to help manage a very agitated delirious patient on a ventilator who was in restraints because of the fear of self-extubation (a common problem psychiatric consultants get called about).

We were sitting in the unit conference room and the unit pharmacist was present. I don’t remember if the attending was there. I started to describe what had been studied in the past, which was continuous intravenous infusions of haloperidol lactate (there are several studies which do not support the use of haloperidol for treating delirium). There was no way to administer oral sedatives. In fact, the patient was being given heavy doses of intravenous benzodiazepines and opioids.

I notice that the more details I shared about the intravenous haloperidol, the wider the pharmacist’s eyes got. Long story short, the MICU resident decided to try something other than psychiatric medication. Indirectly, you could say I was using a motivational interviewing technique to teach. But Murray would have described that as Olympian and in any case, I didn’t consciously do that. All I had were facts and I told the resident what they were. A matter-of-fact approach and tact can be part of a liaison approach, but that’s not what Murray was concerned about and probably not what he saw from most liaison psychiatrists.

And I had to work hard not to display testiness (much less loftiness), which I’m afraid I didn’t always do.

Costa Rica Tarrazu Comes in K-Cup Pods Now!

Sena ordered some Costa Rica Tarrazu coffee in K-Cup pods. There are two varieties, a medium roast and a dark roast. Tarrazu coffee always reminds me of our time spent in Madison, Wisconsin years ago. There were so many fun things to do and interesting sights to see.

OK, so the dark roast is extra bold and is supposed to have lemon, red honey, and bright notes. The medium roast is mild-bodied and is supposed to have honey, baker’s chocolate, and bright notes.

I really don’t notice the different notes. They’re both very smooth and we enjoyed them. I can’t distinguish coffee notes, yet I can tell that shredded coconut has a consistency very much like cellophane. That’s why I feel so squeamish about swallowing it and seem like a cow chewing its cud—endlessly.

I wouldn’t know how to tell red honey from plain old honey. If the medium roast has baker’s chocolate notes, then they must be like the notes played on an imaginary chocolate piano.

It occurs to me that I could be wrong about this coffee being smooth. If the notes are supposed to be bright, then maybe it should be acidic, which is not smooth. This is because some coffee tasting experts say that smooth coffee is low in acid, although low acidity can make a coffee unexciting and boring.

I’m not bored at all by Tarrazu coffee. On the other hand, I can’t say that coffee has ever excited me. I’ve been stimulated by it, which is because of the caffeine, not the notes.

Most of the web references about coffee flavor lingo appear to be written by companies that sell coffee. There is a whole vocabulary about the subject. It’s similar to wine-tasting in which there are also notes and possibly chords.

We have a good supply of Tarrazu coffee pods. I imagine our palates will soon be educated enough to detect whole symphonies of notes resembling works by the 4 Bs: Bach, Beethoven, Brahms, and Bigfoot. If you detect beef jerky notes and hear loud knocks while drinking coffee, you should consider switching to Tarrazu.
