Why Emergency Physicians Are Built for Ketamine Clinics
The Case for Emergency Physicians Opening a Ketamine Clinic: Evidence, Honesty, and Finding Your Why
Synopsis: Emergency physicians bring a unique combination of clinical skill, procedural confidence, and schedule flexibility to the ketamine clinic space. This pillar post covers the clinical evidence for IV ketamine across depression, anxiety, PTSD, and chronic pain, why EM training is a genuine advantage, the honest financial and emotional reality of opening a clinic, and the one question every clinician needs to answer before they do anything else.
Key Takeaways:
Emergency physicians are among the most naturally equipped clinicians to open and run a ketamine clinic. They bring procedural confidence with ketamine, direct experience treating depression, PTSD, chronic pain, and suicidal ideation, and a schedule structure that creates space for private practice.
The clinical evidence for IV ketamine across multiple conditions is substantial and growing. But before any of the how matters, one question determines everything: why are you doing this?

Emergency physicians have the clinical skills, schedule flexibility, and patient experience to make exceptional ketamine providers. Here is the full picture before you decide.
Introduction
A friend of mine once asked me to imagine a swimming pool filled with toxic waste. Every kind of gunk you can think of. Everything you would never want to go near.
Would you jump in?
Heck no. Why would I do that?
Then he asked: what if your daughter or your son was on the other side of that pool? What if it was someone you loved?
Would you jump in then?
Of course. Without thinking twice.
That is the why. That is the thing that will get you through the paperwork and the slow months and the colleagues who look at you like you have lost your mind. If your why is strong enough, you will get through all of it. If it is not, the hard parts will win.
I shared that story at the American College of Emergency Physicians Scientific Assembly. And I am sharing it here because it is still the most important thing I can say to any EM physician who is thinking about opening a ketamine clinic.
Not the science. Not the financials. The why.
Everything else follows from that.
Depression, PTSD, anxiety, and chronic pain affect hundreds of millions of people worldwide. Emergency physicians see the consequences every shift. IV ketamine therapy offers a faster, more targeted path to relief for patients who have exhausted conventional treatment options.
The Mental Health Crisis That Makes This Work Urgent
You already know these numbers. You see the consequences of them every shift.
More than 300 million people worldwide are affected by depression. It is the leading cause of disability globally. Over 17 million people in the United States live with severe chronic pain. One in five people are affected by a mental health condition. And suicide has increased 33 percent from 1999 to 2017. It is the second leading cause of death among Americans between the ages of 10 and 34. Internationally, 800,000 people die by suicide every year.
And the tools we have been relying on are not keeping up.
SSRIs take two to three months to reach therapeutic effect. Only about 20 out of 100 patients actually improve on them. The side effect profile is real and it is significant: GI issues, sleep disturbances, sexual dysfunction, fatigue, headaches, and a kind of emotional flatness that some patients describe as trading one problem for another. And on top of all that, we are still in the middle of an opioid epidemic that has complicated chronic pain management across the board.
When someone is in severe mental health pain or severe physical pain, undertreated and running out of options, the risk of suicide goes up. You know this. You have been in that room.
Ketamine is not a cure for all of this. But it addresses a part of the treatment gap that nothing else currently does, and it does it faster than anything else in the psychiatric toolkit.
That is the backdrop. That is why this work matters.
What the Clinical Evidence Actually Shows
I want to walk you through the evidence because I think you deserve to see it clearly, not as a sales pitch, but as a fellow clinician who has reviewed it seriously.
| IV ketamine: clinical evidence by condition | |||
| Condition | Key study | Finding | Clinical takeaway |
|---|---|---|---|
| Depression | Berman et al. 2000 (proof of concept); NEJM 2023 (ketamine vs ECT, n=400); JAMA Psychiatry 2024 (secondary analysis) | Ketamine produced significant drops in depression scores vs placebo. Non-inferior to ECT in the largest head-to-head trial. Secondary analysis suggested outpatients may prefer ketamine over ECT. | Rapid, sustained antidepressant effect with a more favorable side effect profile than ECT. More than 140 clinical trials now support use. |
| Anxiety | Glue et al. (escalating dose study, n=12) | 83% of patients with generalized anxiety, social anxiety, and panic attacks reported greater than 50% reduction in anxiety scores. Results lasted 3 to 7 days. Multiple infusions extended duration. | Meaningful response rates in patients who had already failed SSRIs and psychotherapy. Dose escalation protocol showed sustained benefit beyond the infusion period. |
| PTSD | Murrough et al. JAMA Psychiatry (single infusion vs midazolam); follow-up study (6 infusions vs midazolam) | Significant improvement in PTSD symptom scores in the ketamine arm vs active placebo in both the single-infusion and multi-infusion studies. | Ketamine outperformed active placebo in a treatment-resistant population. Six-infusion protocol showed robust and replicable results. |
| Chronic pain | Orhuru et al. systematic review and meta-analysis | IV ketamine benefits lasted up to two weeks post-infusion. Higher doses and longer infusion durations produced more durable results. Most effective for neuropathic pain and central sensitization. | Best suited for CRPS, fibromyalgia, trigeminal neuralgia, postherpetic neuralgia, and peripheral neuropathy. Less consistent evidence for mechanical pain such as osteoarthritis. |
Note: This table summarizes evidence referenced in clinical literature and the Ketamine Startup Podcast. Individual patient response varies. This is not a clinical recommendation.
The starting point is a 2000 study by Dr. Berman and colleagues. Small sample, just seven patients. But it was randomized, placebo-controlled, and double-blinded. They used IV ketamine at 0.5 mg/kg infused slowly over 40 minutes compared to saline placebo. And what they found was a significant drop in depression scores in the ketamine group. That small study opened an entire field.
In the years since, more than 140 clinical trials have examined ketamine as a treatment for mental health conditions. A recent meta-analysis synthesizing approximately 10 years of data confirmed that yes, IV ketamine is effective for depression.
The most significant head-to-head comparison was published in the New England Journal of Medicine in May 2023. IV ketamine versus ECT, electroconvulsive therapy, which is the current gold standard for treatment-resistant depression. Four hundred patients, 200 in each arm. The finding: ketamine was non-inferior to ECT. Just as effective. Without the memory loss, without the cognitive side effects that come with ECT. A secondary analysis published in JAMA Psychiatry in June 2024 went even further, suggesting that outpatients and those with moderately severe to severe depression may actually prefer ketamine over ECT for their treatment.
For anxiety, a study by Dr. Paul Glue and colleagues out of Australia looked at 12 patients with generalized anxiety disorder, social anxiety, and panic attacks who had already tried various SSRIs and psychotherapy. They used escalating doses of ketamine. And 10 out of 12 patients, that is 83 percent, reported greater than 50 percent reduction in their anxiety scores. Those results lasted not just during the infusion period but for days afterward. Multiple infusions helped extend the duration of benefit even further.
For PTSD, a proof-of-concept study published in JAMA Psychiatry used a single infusion of IV ketamine versus midazolam as an active placebo. Significant improvements in the ketamine group. A larger follow-up study then moved to six infusions versus active placebo and found the same result, a significant improvement in clinician-administered PTSD scores for patients in the ketamine arm.
For chronic pain, and specifically neuropathic pain and pain driven by central sensitization, a systematic review and meta-analysis found that benefits from IV ketamine lasted up to two weeks post-infusion. Higher doses and longer durations produced more durable results. The conditions that respond most consistently include complex regional pain syndrome, fibromyalgia, trigeminal neuralgia, postherpetic neuralgia, and peripheral neuropathy. For pain that is more mechanical in nature, like bone-on-bone osteoarthritis, it has not been as consistently effective.
The evidence is not perfect. No evidence base ever is at this stage. But it is substantial, it is growing, and it is clinically meaningful.
Ketamine's antidepressant effects go beyond receptor blockade. By increasing BDNF and triggering neuroplasticity at the circuit level, IV ketamine can produce measurable changes in depression, PTSD, and chronic pain within hours rather than weeks.
How Ketamine Works: What You Already Know and What Might Surprise You
You probably already know this part. Ketamine is an NMDA receptor antagonist. It works on the neurotransmitter glutamate. And glutamate is not a minor player. It comprises roughly 90 percent of the neurotransmitters at the synapse. We think about dopamine and serotonin and norepinephrine, but the vast majority of what is happening at the synapse is glutamate.
By blocking NMDA activity, ketamine produces its analgesic and anesthetic effects. That part you know.
What might be less familiar is what is happening downstream.
Ketamine is not a selective drug. It is not like a beta blocker hitting one specific receptor subtype. It works on a host of receptors: NMDA, opioid, dopamine, serotonin, acetylcholine, GABA, nitric oxide. The breadth of its action is part of why it is so pharmacologically interesting.
Here is what chronic stress does at the cellular level. Whether that stress is coming from depression, anxiety, PTSD, or chronic pain, it drives extracellular glutamate up. That excess glutamate creates excitotoxicity. And excitotoxicity causes dendrites to retract and synaptic spine density to decrease. The brain's physical architecture is being worn down by the ongoing burden of the illness.
Ketamine reverses this. It increases brain-derived neurotrophic factor, or BDNF. That increase promotes protein synthesis, synaptic strength, and synaptogenesis. The result is neuroplasticity: the brain rebuilding the connections that chronic stress has damaged, reopening critical learning pathways, resetting sensitized pain receptors.
This is why ketamine can work within hours rather than weeks to months. It is not waiting for a slow reuptake adjustment. It is triggering a structural change at the circuit level.
There is one more thing worth holding onto here. There is a quote that has stuck with me: studying neurons to understand consciousness is like studying words to understand Shakespeare.
The dissociative and at times transcendent experiences patients have during ketamine infusions may not be side effects to be managed. There is a growing body of thought suggesting those experiences are part of the therapeutic mechanism itself. The neuroscience of consciousness has not fully caught up to what we are seeing clinically. But it is worth staying curious about rather than dismissing.
Why Your Emergency Medicine Training Is an Unfair Advantage
I want to make something clear. When I started talking about opening a ketamine clinic, some of my colleagues thought I was walking away from emergency medicine.
I was not. I was extending it.
Emergency medicine is not a location. It is a mindset. And that mindset turns out to be one of the best possible preparations for this work.
| Your emergency medicine training as a ketamine clinic advantage | ||
| EM skill | Ketamine clinic application | Why it matters |
|---|---|---|
| Ketamine familiarity | You have administered IV ketamine hundreds of times. You know the dosing ranges, the adverse effect profile, the monitoring requirements, and how to respond when something unexpected happens. | You are not learning a new drug. You are applying one you already know deeply in a different clinical context. That confidence translates directly to patient safety and session quality. |
| Procedural sedation monitoring | Monitoring a patient through a dissociative state, recognizing and responding to adverse events, and managing airway and hemodynamic stability are core EM competencies that map directly to ketamine infusion oversight. | Most clinicians entering the ketamine space need to build comfort with monitoring patients in altered states from scratch. You already have it. That is a meaningful clinical and liability advantage. |
| Patient population experience | You have treated patients in severe depressive crises, with PTSD, with treatment-resistant anxiety, and with chronic pain at 2am when things are at their worst. These are the same patients ketamine clinics serve. | You are not encountering these types of patients for the first time in a clinic setting. You know how to hold space for serious illness, build trust quickly, and make sound clinical judgments under pressure. |
| Schedule flexibility | EM physicians can scale shifts up or down, build their own schedules, and create protected time for a private practice without walking away from the income security of hospital-based work. | The early months of a ketamine clinic are slow. Cashflow is unpredictable. Most clinicians have to absorb that risk on a fixed salary with no wiggle room. EM shift flexibility means you can scale your hospital hours up or down to match where the clinic is financially. That is a real advantage most people in this space do not have. |
Think about what you already bring to this space.
You have administered IV ketamine. Many of you have done it hundreds of times. You know the dosing, the monitoring requirements, the adverse effect profile. You are not learning a new drug. You are applying one you already know in a different clinical context.
You have experience treating the exact patient population that ketamine clinics serve. Patients in severe depressive crises. Patients with PTSD who have been through the conventional treatment pathway and are still suffering. Patients with chronic pain who have been on opioids for years and are looking for a real alternative. These are not new patient profiles for you. You have been in that room at 2am when they are at their worst.
You are comfortable with procedures, with monitoring patients during sedation, with making fast decisions when something unexpected happens. That clinical comfort translates directly to this treatment.
And then there is the schedule. This is something that is actually pretty unique to emergency medicine. You can pick up more shifts, you can do fewer shifts, you have the potential to build your own schedule. That flexibility creates real space to develop a private practice on the side. And a ketamine clinic, especially in the early stages, is very much something you build on the side.
I want to also acknowledge something about the broader landscape. The Annals of Emergency Medicine, published that there is a predicted surplus of nearly 8,000 emergency physicians by 2030. There is increasing administrative burden, increasing corporate practice of medicine, decreasing reimbursement rates, and less autonomy for physicians in the ED system. That is not a criticism. It is the reality of where the specialty is heading structurally.
Your EM skill set is extraordinary. The question is whether the traditional setting is the only place it belongs. I would argue it is not.
Running a ketamine clinic is not a passive income stream. It demands time, operational attention, and resilience through the early months. For physicians driven by autonomy, purpose, and the mission of the work, the rewards are significant and deeply personal.
The Honest Financial and Emotional Reality
I want to be honest with you here because I think full disclosure matters more than a motivational pitch.
Ketamine therapy is not covered by insurance in most cases. It is cash pay. Some people hear that and immediately think it sounds lucrative. And there is real revenue potential, but there will be countless hours working on your clinic that will never go compensated.
The hours you spend on marketing. On HR. On staffing. On ordering gauze and syringes and managing a building and handling the hundred operational details that keep a practice running. You aren’t getting paid, and if you’re not doing them well that means you’re paying someone else. Plus in the early months, you may genuinely be making more money working full-time EM shifts than you are running the clinic.
Running a ketamine practice is like having a newborn. It is on your mind constantly. There is no clocking out. When I was working in the ER I knew that at a certain time my shift ended and I was free, aside from the occasional thought about whether I should have ordered that CT. The clinic is not like that. It is with you.
I am telling you this not to discourage you. I am telling you this because if you go in without knowing it, the reality will catch you off guard. And if your primary motivation is financial, that reality will likely outweigh the rewards.
So what is on the other side?
For me, it is freedom and autonomy. Creating my own schedule. Building something that reflects my own clinical values. Practicing medicine on my own terms rather than within a system that is increasingly moving away from physician-led care.
It is the cutting edge. I love being at the front of something. Whether it is ketamine therapy or stellate ganglion blocks or whatever is next, being in that space where the evidence is still being written and the best practices are still being figured out, that is genuinely exciting to me.
And it is the patient impact. That is the real answer. I have had patients tell me that if they had not pursued this a year ago, they do not think they would still be here. You cannot put a number on that. But it is what makes every hard week worth it.
The clinicians who build sustainable ketamine practices are not the ones with the best business plan on day one. They are the ones with a clear and personal sense of why this work matters. That why is what carries you through the hard parts.
Before You Think About the How, Get Clear on the Why
I see a lot of clinicians coming at this from the wrong direction. They want to know about the business structure and the protocols and the build-out costs and the compliance requirements. All of that is important and we cover it extensively in our blog, podcast, and course.
But none of it matters if you do not have a strong enough why to carry you through.
Because I promise you the hard parts are coming. There will be paperwork. Business will be slow at first. Cashflow will be unpredictable. There will be colleagues who question your decision. There will be weeks when you wonder what you were thinking.
A strong why gets you through all of that. A weak one does not.
Back to the swimming pool.
Would you jump into a pool of toxic waste for a financial opportunity? Probably not. But for your daughter, your son, your person, you would not think twice. You would jump.
What is your version of that? What is waiting for you on the other side of this that is worth jumping in for?
That is the question to answer before anything else.

Frequently Asked Questions
Are emergency physicians good candidates for opening a ketamine clinic?
Emergency physicians are among the most naturally prepared clinicians for this space. They have direct clinical experience with ketamine as a procedural sedation agent, comfort managing patients in altered states, and familiarity with the patient populations most likely to benefit from ketamine therapy including depression, PTSD, anxiety, suicidal ideation, and chronic pain. The procedural, monitoring, and pharmacological competencies required for safe ketamine infusion therapy map directly onto EM training. Schedule flexibility in emergency medicine also creates real space to develop a private practice alongside hospital-based work.
What clinical evidence supports IV ketamine for depression?
The evidence base spans more than two decades. A landmark 2000 study by Berman and colleagues established proof of concept. A 2023 New England Journal of Medicine trial comparing IV ketamine head to head with ECT in 400 patients found ketamine non-inferior to the current gold standard for treatment-resistant depression, with a more favorable side effect profile. A 2024 secondary analysis in JAMA Psychiatry suggested outpatients with moderately severe to severe depression may prefer ketamine over ECT. More than 140 clinical trials have examined ketamine across mental health conditions.
How does ketamine work as an antidepressant?
Ketamine is an NMDA receptor antagonist that works primarily on the neurotransmitter glutamate, which comprises approximately 90 percent of neurotransmitter activity at the synapse. Chronic stress from depression, PTSD, or chronic pain drives excitotoxicity that physically degrades synaptic structure over time. Ketamine counters this by increasing brain-derived neurotrophic factor, or BDNF, which promotes synaptogenesis and synaptic strength. The result is neuroplasticity, the rebuilding of degraded brain circuits, which is why ketamine can produce measurable antidepressant effects within hours rather than the weeks required by SSRIs.
Is opening a ketamine clinic financially worth it for an EM physician?
This depends on what you are optimizing for. Ketamine therapy is cash pay in most cases but involves significant uncompensated administrative time in marketing, staffing, operations, and clinical management. In the early months, a full-time EM salary may exceed clinic revenue. The physicians who find the most sustainability in this work tend to be motivated primarily by autonomy, clinical purpose, and the mission of the work rather than income. If financial return is the primary driver, the emotional and operational demands of building a practice are likely to outweigh the returns, at least in the early stages.
What EM skills translate directly to ketamine clinic practice?
The most directly transferable skills include procedural comfort with IV ketamine and procedural sedation, patient monitoring during altered states, clinical experience with the conditions ketamine treats, and the ability to respond rapidly when unexpected events occur during a session. Beyond clinical skills, EM physicians bring a systems orientation and comfort with high-stakes decision-making that translates well to the operational demands of independent practice.
How do I know if I am ready to open a ketamine clinic?
The most important question is not logistical. It is motivational. Clinicians who sustain successful ketamine practices tend to have a clear and personal sense of why this work matters to them, something stronger than income or schedule flexibility. Practically, readiness includes the clinical foundation to supervise ketamine infusions safely, the financial stability to sustain a practice through the early months when volume is building, and access to mentorship and education from those who have already navigated the process. That is exactly what our Ketamine StartUp platform was built to provide.
