Principles of Pain Management With Dr. Beth Hogans

Neurologists bring special skills to pain evaluation and management and are well equipped to appreciate both the focal and diffuse nature of pain. By using expert knowledge of the nervous system and implementing relevant therapies, neurologists can succeed at and find meaning in optimizing patient outcomes.

In this episode, Allison Weathers, MD, FAAN, speaks with Beth B. Hogans, MD, PhD, author of the article “Principles of Pain Management,” in the Continuum October 2024 Pain Management in Neurology issue.

Dr. Weathers is a Continuum® Audio interviewer associate chief medical information officer at the Cleveland Clinic in Cleveland, Ohio.

Dr. Hogans is an associate professor in the department of neurology at Johns Hopkins School of Medicine and an associate director for education and evaluation at the Geriatric Research Education and Clinical Center at the VA Maryland Health Care System in Baltimore, Maryland.

Dr Weathers: This is Dr Allison Weathers. Today I'm interviewing Dr Beth Hogans, author of Principles of Pain Assessment, Diagnosis, and Management from the October 2024 Continuum issue on pain management and neurology. Welcome to the podcast, and please introduce yourself to our audience.

 

Dr Hogans: Good afternoon. My name is Beth Hogans. I'm a neurologist. My faculty appointment is at Johns Hopkins School of Medicine in the Department of Neurology, where I'm an assistant professor. I also serve at the Baltimore VA Medical Center, where I'm the Associate Director of Education and Evaluation for the Geriatric Research, Education and Clinical Center, as well as a neurologist.

 

Dr Weathers: Thank you so much for, again, being with us today and taking the time to speak with me. I was really struck by how broadly applicable this topic is, not only to all neurologists, but to all physicians and even to all of our listeners, given how prevalent these conditions are.

Nearly all physicians involved in direct patient care treat some type of pain disorders, and we all experience pain at some point, though hopefully not chronic pain. Well, usually like to start with a question - again, it feels especially pertinent here in getting to speak with you - what is the most important clinical message of your article?

Dr Hogans: So, I'm going to say there's two key messages. The first one is that all pain has a differential diagnosis, and the second one is that all meds work better with non-pharmacological and whole-health comprehensive management incorporated. So that's why I structured the article around the ideas of assessment, diagnosis and management. It's a pretty sort of traditional, basic approach to how we look at clinical problems, but we definitely want to start with proper assessment, go on to a thoughtful differential diagnosis, and then move towards a management plan that is not just, you know, one stop shop, but actually kind of brings several aspects together. Because pain is so multidimensional; you know, it's represented in multiple places in the brain as well as other levels of the nervous system. And so, I think we're still in an era, and we may stay in an era, of, you know, needing something to go along with medication in many cases.

 

Dr Weathers: I think those are two absolutely critical points for our listeners to keep in mind, both, again, keeping that broad differential, and - we'll get more into management in a bit, but again - that dual strategy of both the pharmacologic and the non-pharmacologic. And again, going down a little bit more there on that management track, a really recurring theme that I picked up in your article is the importance of interprofessional collaboration in the assessment and the management of patients with pain. In the abstract, you actually use the phrase “remarkable” for the diversity of health professions, which I really loved. What other clinicians do you work with in diagnosing and managing pain conditions, and what are their roles in the care of these patients?

Dr Hogans: So, something you hear over and over again at pain meetings is, “there is no I in team.” They say that all the time. And it's one of the things I really love about pain, is that we get to work with great colleagues who have their own perspectives, approaches and therapies for pain. So, in my particular practice, which I do focus kind of more at the interface between neurological and musculoskeletal pain because of my passion and interest for spinal pain, you know, ranging from neck to tailbone, but most especially in the lower back. Physical therapy, clinical psychology, sleep sedicine, nursing, pharmacy, rehab… Podiatry is something that people don't often think of, but is really important for getting spine mechanics correct… Ergonomics. But I want to just say something about clinical psychology because there may not be enough clinical psychologists in the United States, but we as neurologists are also brain doctors. You know, we have to stay within our scope of practice. But there's a move now to talk about psychologically informed physical therapy. So why don't we talk about psychologically informed neurology? I think we could do an even better job of kind of leveraging our knowledge of the brain and how it works to kind of bring that into our practice. And so, people with pain often need a lot of empathetic support, for example, as well as knowledge about their condition.

So, I would encourage people to build local networks of folks that they refer to and work with. Because when I was a younger doctor, physical therapists taught me a lot of what I know now - because I didn't get it at med school, although by the time I got to residency, I had some really great teachers. But clinical psychology, PT, sleep medicine, those are, like, almost all-the-time collaborators for me. And then like I said, nursing, pharmacy, rehab, podiatry, et cetera, et cetera, prosthetics… those things are all important for pain.

Dr Weathers: I was struck by the quote, “one of the things I really love about pain.” That's a great line, and understand how it was meant, but I think - again, a really great quote, but I think you make such important points and, really, it is such a critical team approach. And I love all of those roles you called out. And I was struck in listening to your really thoughtful answer about how I've spoken with several other authors of actually very different topics, but about how we're thinking now about a trauma-informed care approach to many neurological conditions and the similarities with this patient population, how it likely informs very much the approach to this patient population as well and probably the significant potential.

 

Dr Hogans: A hundred percent! And so, for example, one of the things that probably does factor in for chronic pain - not in everyone, but in, let's say, many cases - is a prior exposure to trauma, whether it's PTSD or adverse childhood events. And so that's why, you know, clinical psychology is, like, very high up on my list of collaborators. And one of the things that I really like - you could say love - about working in the BA system is the ready availability of mental health co-management. So, I would say about a third of my patients in neurology are co-managed by mental health. And what it does is it sort of defuses a lot of what would otherwise come into the visit and be my job as a neurologist to manage, if not treat, right? I still have to manage, you know, someone who comes in with untreated mental trauma or mental health conditions if they're coming into that visit, and I'm trying to open the topic of whether mental health co-management could be helpful. That can sometimes, strangely enough, antagonize people. We’re still in an era of substantial stigma. But I can just say the practice of neurology, together with appropriate mental health co-management, is far superior than going alone.

Dr Weathers: Absolutely. And how fortunate that for a lot of your practice, your patients do have those resources available to them. And I think it speaks to the importance of those resources, that all of our patients should really have that availability, and the importance of access.

Dr Hogans: Right. So, at Johns Hopkins, we also have exceptional access to, you know, some of the world 's best clinical psychologists. And I've been really privileged to work with my colleagues in clinical psychology. The challenges that - in some of my roles, I interact with trainees and learners who are in clinics that are not as well resourced. And therein lies just tremendous heartache and difficulty. We've been trying to build some resources. There are federal resources that can help to open those conversations and maybe take some of the initial steps towards things like cognitive behavioral therapy, acceptance commitment therapy, mindfulness-based stress reduction. There's many of these psychological therapies that are proven to be effective for pain and chronic pain, and yet we haven't really had that conversation as a society about, how do we get people connected with those therapies? Many of them can be delivered on a larger scale. And I think we just need to think a lot more thoughtfully about, how can we have more of a public health approach to chronic pain and wellness?

Dr Weathers: Absolutely. Such really important points. So, we've talked about the really kind of important, obvious points for what we very much kind of know to be accurate. I want to talk now about, what are the most common misconceptions that you've encountered in treating patients with pain disorders?

 

Dr Hogans: Yeah. So, this is where, you know, physician as advocate for the patient really comes into play. So, I think the number one misconception that I and many of my colleagues encounter: that pain is the patient 's problem, or that that pain reflects an excessive sensitivity.

I think one analogy that I use with students that helps to kind of piece this apart is the immune system, right? There are people who have immunodeficiencies that they're not sufficiently protected from the environment, and then there are - lots of people have allergies where their immune system is sort of hyper-alerted to things that are not a true threat. And the pain system is exquisitely regulated. The neurology of the pain system is fascinating and compelling, and once you learn a little bit about it, you can apply it at the bedside, time after time after time.

So, number one: pain is real. And there is an association between strong pain and increased risk for chronic pain. And then sort of the flip side of that is that malingering or, you know, fictitious pain is probably a lot like other functional disorders in that it's part of a complex. So, I think we need to do a lot more work to discover, you know, quote, what is pain that people think is amplified or manufactured and how can we frame that in a clinical context rather than just casting blame or- we already mentioned stigma. You know, stigmatizing people does not help. And there are people who have real pain problems that are really severe and disabling, and neurologists can actually help support those people as they encounter their environment.

Dr Weathers: I really love that response. And I think you're right in that we do so often, in the medical system, tend to stigmatize these patients, even as we say the right things and we, I think, talk about it and we recognize… and yet, still, it's almost these unconscious biases. I think, as good as we've gotten in some areas, it's still hard to separate them. It's almost kind of one of the last unspoken, still-acceptable ones in some ways that oh, they must be drug-seeking or, you know, to your point, you use the word, kind of malingering, that they’re somehow, you know, either at fault or that there's some nefarious behavior going on there. And I think you made such really important points that we have to change our way of thinking that it is such a common and, frankly, wrong misconception that a lot of us really carry around and it's really hard to break. We have to kind of recognize these biases in ourself and really fight against them when we encounter these patients.

Dr Hogans: I think part of how we got there is the opioid crisis.

Dr Weathers: Yes.

Dr Hogans: You know, unfortunately we still do not have a fantastic understanding of opioid durability. Like, how long does opioid analgesia last? Not from, like, hour to hour, but, like, from month to month. Roger Cho has done some awesome work looking at long-term efficacy of opioids, and it's surprisingly modest. And yet, opioids have this profound kind of behavioral impact, that they really are highly reinforcing. And so, once they're in the conversation, you find yourself in, like, almost this life-or-death struggle between, you know, am I going to get opioids at this visit? How many? You know, if not, why not; are you going to decrease? And so those of us who are working today, you know, and have been working for the last five years, have been through this terrible struggle. And that struggle is not yet resolved. But once opioids are kind of off the table or neutralized, then we actually have a conversation that is really, you know, A: how good of a clinician are we? Do we really understand what our patient is going through? And how can we bring, like Hippocrates said, you know, get the system to bear on the problem and not just, you know, try to throw drugs at it. So I think that, really, pain challenges us to be our best selves and to, you know, really be clever and kind and helpful. And it is a really great opportunity to help. And as I said, the mechanisms of pain are fascinating neurologically. So, it kind of satisfies some of what we come to work for, but I think it's not all done yet. One of my challenges has been, I wrote an article in 2011 with one of my trainees where we counted up the number of hours documented in the double AMC database for med schools, and we found that the modal value for US medical schools at that time was four. So out of four thousand curricular hours, there were four pain hours. And when you think about the prevalence of pain, that's just a drop in the bucket. So, you know, it's getting better, but we need to come up with some new strategies. So I wrote, I've written three books now. The latest one is really designed to give that intro-level knowledge of pain. But also, obviously, the Continuum article, I wanted to kind of set the table, lay the foundation, and give people some core knowledge to get started with.

Dr Weathers: And again, a fantastic article. If our listeners haven't read it, I strongly encourage them to go back because I think you did just that. And as you were just talking, I was thinking about that, especially for those of us who, you know, depending on when in your training was, you know, mine started in the early 2000s. We've kind of lived through that era with the pendulum swinging. Where was, you know, the signs were posted in each clinic room. You know, don't forget to ask, you know, your provider about your pain meds, and it was the sixth vital sign, and all of that. And then the pendulum swung very quickly and very severely the other way, where it was, you have now created this problem, right? We have all caused this epidemic and we're supposed to immediately take these meds away, right?

And now to your point, you know, we've all been in these situations with opioids where that was all that was talked about, right? So, you know, we've all been on call and now you're getting the call overnight from people trying to get their opioids filled when, you know, not their prescriber because they knew if they called - or family members, as soon as you got prescribing rights, were now calling and asking. And we've all been in these very hard situations.

Dr Hogans: Just because you have a hammer doesn’t mean that everything is a nail.

Dr Weathers: I know. So, in trying to negotiate and navigate, you know, these very rough situations… And I think now we're reaching kind of this new era where, to your excellent point, realizing that there are a lot of other solutions. And I love how you framed it, that this is really where we can be our best selves as providers. And actually, to that point, so - as I've mentioned on this podcast many times, clinically, I'm a neuro-hospitalist and I actually wanted to get your opinion as one of the foremost experts. So, a challenging situation I'm also often faced with in my clinical role is when a patient with a chronic pain condition such as diabetic neuropathy or lumbar radiculopathy is admitted to the hospital, often with a totally unrelated condition that either results in a new acute pain, but often also exacerbates their underlying chronic pain, what's your approach to the assessment and management of similar cases? I know our listeners will return again and again to that fantastic approach you laid out in Figure 1.1 with the coordination of the pharmacologic and non-pharmacologic therapies, as we've talked about several times just throughout our conversation, how important both of those approaches are. But a lot of those options are unfortunately limited in the in-patient setting. So how do you balance those?

Dr Hogans: So, there's a whole other toolkit that comes into play for acute pain or sort of pain palliation. And you actually have some important allies in the hospital. It turns out that nurses, generally speaking, have some more education than do most physicians about pain.

And the nurses that I encounter really see themselves as genuine, sincere advocates for the patient 's interest. They're at the bedside, they're working very closely, and their training actually does, I think, give them a number of tools and a set of inspirational ideas that build towards patient comfort. So, if you communicate with nursing staff about your desire to provide more comfort for the patient, whether it's padding, positioning, activities such as, you know, having them participate in something, you know, whether it's just having a family member, you know, take them for a walk, whether it's in a wheelchair or having an older adult sit by the nurse's station just to give some form of distraction. Ice, you know, cool packs and hot packs, you know, supportive toweling or pillows, all of that can really help. Years ago, nurses used to actually be trained in giving massages, and that can provide some comfort. You know, supportive touch is kind of how we frame that nowadays. But the other piece that you have is, in many cases, PT is getting involved much earlier in the patient, you know, rehabilitation course. And remember that motion is lotion. So, our endogenous analgesia system, which actually involves both endogenous opioids and endogenous cannabinoids, can be activated through many forms of motion, as well as immobility is actually a cause of pain itself. So, you just, you break out your in-patient tool kit and, you know, there are other tools and there's other allies that you want to think about in that context.

Dr Weathers: Those are all really great tips, many of which, I know, as you said, a lot of us tend in our thinking to go right to pharmacologic strategy, so wouldn't even be considered, but I think really thoughtful, and that we do have at our fingertips. So-

Dr Hogans: I wish I had thought to put them in the article.

Dr Weathers: No, they were fantas- but again, why we podcast, agree for complimenting the article… we encourage people to take advantage of both. Well, this has been wonderful, and I know I have learned so much, even more than was in the article. I always like to end on a hopeful note, so I would love to hear what developments in the field of pain that you're most excited about. What do you think is coming down the pipe?

Dr Hogans: Well, I think, like a lot of people, I've been waiting for the opportunity that's happening right now, which is, there's a massive investment in pain science being made by the NIH. Finally. You know, we've moved from, you know, just like, little things here or there, commercial kind of entities, to, we now have large NIH dollars flowing into pain. I'd like to see not only a focus on small molecule development, which will ultimately lead to better pharmacological agents, but I'd also like to see a thoughtful approach to non-pharmacological therapies, whole health approaches. Things like healthy communities, safe exercise spaces for all ages, more nutritious food, yoga, Tai chi. We know from Skelly and Cho's article in 2020 that there are many, many non-pharmacological therapies that actually work for chronic pain. There’re some things we still don't know. Like, do older adults respond as well as middle-aged adults? And how can we get NPTs - non-pharmacological therapies - more accessible to people who are subject to disparities? I think part of what happened during the opioid era is that you could get, you know, a bottle of pills for a four-to-ten dollar co-pay and physical therapy was twenty dollars a shot. And we know PT will get you to a better place, but that person that you're talking to may not have three hundred dollars to go to a course of PT. And we need to figure out, you know, how do we do this better, safer, more healthfully.

Dr Weathers: And, I think, forgetting even the co-pay; it's the coordination, the time off work, all of it, right? So it's, I think, all of those challenges, but I think all of that are such important points about - and I think, that's really where I'm hopeful. Right? The emphasis, we talked a little bit about trauma-informed care earlier in our conversation, but the focus now on addressing the underlying social disparities of health and overall healthcare disparities, I think, is so promising.

Dr Hogans: We need to think about the long-term consequences for human health; and pain has a terrible impact on human health for many reasons, and, I hope, will continue to be the focus of effort for years to come.

Dr Weathers: Absolutely. Well, that is such an important statement to end on. Thank you again, Dr Hogans, for such a fantastic conversation and again, such an overall excellent article.

Dr Hogans: Thank you, Dr Weathers, it was great to speak with you today again.
