Chapter 84: Palliative and End-of-Life Care

Welcome to Last Minute Lecture.

This free chapter overview is designed to help students review and understand key concepts.

These summaries supplement, not replace, the original textbook and may not be redistributed or resold.

For complete coverage, always consult the official text.

Usually when we talk about a medical diagnosis, there's this underlying expectation of precision, right?

It almost feels like engineering.

Yeah.

You know, you break your arm.

The x -ray shows that jagged white line and the provider just points at the screen and says, there it is.

That's the problem.

It's very binary.

It's either broken or it's not broken.

And that gives both the patient and the provider a very clear target to aim at.

And we crave that clarity.

I mean, we really like things to be visible, to be categorized, and most importantly, fixable.

Medical training is heavily, almost exclusively, built around this idea of curing the problem.

Right.

But then you step into the world of chronic progressive illness.

You enter the end of life and suddenly, you know, that x -ray machine doesn't really help much anymore.

So today we're looking at what is probably the hardest pivot you will make as a provider.

Oh, absolutely.

It's that moment you realize curing the disease is no longer possible, but healing the patient still is.

Yeah.

And moving from, you know, curing a disease to managing the holistic experience of dying, it requires an entirely different set of clinical, pharmacological, and emotional skills.

It really is the absolute definition of a medical paradigm shift.

Which is exactly why we're doing a highly focused deep dive today, specifically tailored for you, the advanced practice nursing student.

So consider this your last minute lecture.

We're glad you're here with us.

Our mission today is to give you a shortcut to mastering Chapter 84, which is palliative and end -of -life care from your primary care textbook.

We're going to use the text as our roadmap to navigate this paradigm shift.

We're basically acting as your one -on -one tutors to prep you for a clinical practice.

And ultimately, for those really difficult moments when you're actually standing in the patient's room, we'll explore the foundational definitions, dive deep into the physiology of symptom management,

tackle the complex pharmacology of end -of -life care, and then we're going to synthesize all of it with a clinical case study at the end.

Right.

But before we can, you know, prescribe anything or assess anything, we have to understand what palliative care actually is.

Because it feels like a relatively modern concept in the grand scope of medical history.

It is, yeah.

The modern hospice movement really only gained traction in 1963.

There was a British nurse and doctor, Dame Cicely Saunders, and she introduced this specialized care for the dying and founded St.

Christopher's Hospice over in London.

Okay.

And then Florence Wald, who was a Yale nursing dean, she actually attended one of Saunders' lectures, visited that London facility, and then brought the whole concept back to the U .S., founding the first American hospice in 1974.

Wow.

So 1974, that's really not that long ago.

And the text also emphasizes Elizabeth Kübler -Ross.

Her work in the 1960s on the five stages of grief completely revolutionized how we treat dying patients.

Oh, it changed everything.

Even though she faced fierce pushback from a medical establishment that basically viewed death as a failure, and it took time for legislation to actually catch up to this new philosophy.

It really did.

We didn't see the Medicare hospice benefit arrive until 1982,

then the Patient Self -Determination Act in 1991, and the VA's comprehensive end -of -life care initiative much later in 2009.

Yeah, and those legislative milestones really shaped the definitions that we rely on in practice today.

Yep.

According to the World Health Organization, palliative care focuses on symptom management, comfort, and quality of life for patients with active progressive diseases.

The critical distinction here… One students really need to grasp.

Exactly.

The critical distinction is that palliative care is based purely on a patient's clinical needs, not their prognosis.

Okay, I want to unpack this a bit and clarify the difference between palliative care and hospice because I know students constantly get tripped up on where one ends and the other begins.

It's a very common point of confusion.

Right, so think of palliative care as a giant umbrella.

It's the wide lane on a highway where you can drive both a hemotruck and a symptom management car at the exact same time.

Hospice on the other hand, is an off -ramp.

You're choosing to exit the curative highway entirely, to focus purely on making the rest of the journey as smooth as possible.

I love that analogy.

It hits the mechanism perfectly.

Because palliative care allows concurrent curative treatments,

but under standard Medicare guidelines,

hospice generally requires a patient to forgo aggressive curative treatments for their terminal diagnosis.

Right.

And it strictly requires a certified prognosis of six months or less.

Though you know, the text does note some emerging exceptions like concurrent care demos and VA benefits where some treatments can continue, but wait, putting on my cautious NP student hat for a second here.

Go for it.

I've heard patients absolutely panic at the word hospice because they think they have to surrender all their daily medications.

Like, don't patients on hospice have to stop everything?

No, not at all.

And as a provider, you must actively dismantle that fear the second it comes up.

Individuals on hospice continue most of their medications,

specifically anything that enhances their daily quality of life.

If an inhaler helps them breathe easier, or a certain medication helps with joint pain so they can walk to the living room, they keep it.

Hospice also covers medications related to the terminal diagnosis, provides durable medical equipment and ensures access to a provider around the clock.

That's a huge relief for families.

It is.

And Medicare actually offers four specific levels of this care.

There's routine home care, general inpatient care, respite care, which is up to five days to give family caregivers a physical break, and then crisis care for uncontrolled symptoms.

So looking at the utilization statistics in the text, there's a massive disconnect here.

Life expectancy jumped to almost 79 years in 2020.

So people are living longer, but they're living with multiple chronic conditions.

And cancer is the leading cause of death for people aged 60 to 79.

Now we historically shifted dying from the home to the hospital.

And while hospice is slowly shifting it back, I think the text says nearly half of Medicare beneficiaries who died in 2017 were in hospice.

We still have this huge problem with late referral.

The late referral is a massive systemic failure.

Over 40 % of Medicare patients receive hospice for 13 days or less.

And more than a quarter get it for a week or less.

That's heartbreaking.

And here's where it gets really interesting because the statistic that caught my eye,

the text cites a study showing that hospice patients actually live an average of 29 days longer than non -hospice patients with similar conditions.

And it costs the healthcare system less.

So if the data says they live 29 days longer and it saves money, why is the average provider still so terrified of making the referral?

Well, it really comes down to the physiological toll of aggressive treatment versus the physiological benefit of comfort.

When you stop bombarding a failing body with toxic curative treatments and instead focus on managing pain and reducing stress, the body can actually rest.

That makes a lot of sense.

And that rest often extends life slightly.

But providers hesitate because estimating a prognosis is incredibly difficult.

They don't want to be wrong, and they fear stripping away a patient's hope.

Delaying this care, however, just leads to immense unmitigated suffering.

And the text makes a point to define suffering holistically, right?

It's physical, psychosocial, and spiritual.

On the physical side, the global disparity is just staggering.

79 % of the world's population consumes only 13 % of the global morphine supply.

Which highlights a massive global failure in treating physical pain.

But on the spiritual side, providers often feel totally ill -equipped to help.

Oh, absolutely.

It's uncomfortable.

But you must address a patient's spirituality with open -ended, inclusive questions.

Simply ask, what does spirituality mean to you right now?

And you have to avoid platitudes.

Right, like saying everything happens for a reason or God has a plan to a dying patient who is in severe pain that's often perceived as highly dismissive.

It shuts down the conversation rather than exploring their actual fears.

Exactly.

Now, because prognostication is so difficult and provider fear is so high, we have to rely heavily on early conversations and advanced directives.

We need those tools to protect patients before a crisis hits.

Yet only a third of older adults actually have advanced directives.

So as an advanced practice nurse, you need to know the specific tools you can use.

First, there's a document called My Five Wishes.

I love that one.

It's incredibly accessible because it uses non -medical language and it even includes sections for personal manages to loved ones, which makes it less intimidating.

Then, for seriously ill patients, you have the MOST or POL -2 forms.

And you really need to know how to decode those acronyms and the forms themselves.

MOST stands for Medical Orders for Scope of Treatment and POL -SD is Physician Orders for Life Sustaining Treatment.

The form has three distinct sections.

First is CPR.

You need to give patients an honest medical description of what CPR actually does to a frail body.

You know, the broken ribs, the intubation, not the sanitized television version.

Yeah, TV makes it look like you just wake up and cough.

Exactly.

Then the second section is Medical Interventions.

And here, the text specifically warns providers against asking the family, do you want us to do everything possible?

That phrase is so dangerous because it implies that choosing comfort -focused treatment means doing nothing.

Which couldn't be further from the truth.

Comfort -focused care is highly active, aggressive symptom management.

It's not giving up.

Not at all.

And the third section covers nutrition and fluids, addressing artificial feeding like surgically -implanted stomach tubes or nasogastric tubes.

Now I've seen families absolutely panic when we talk about withholding artificial nutrition at the end of life.

They feel like they are literally starving their loved one to death.

How do you counter that deeply emotional reaction with actual clinical physiology?

You have to very gently explain that a dying body is fundamentally different from a healthy body.

As the organs systematically shut down, the body simply cannot process artificial nutrition or heavy IV fluids.

It just sits there.

Right.

If we force fluids or tube feeds into a failing system, it doesn't nourish them.

It actually causes harm.

The fluid backs up and leaks into the lungs, causing aspiration pneumonia, or it leaks into the tissues, causing severe painful edema and skin breakdown.

The lack of appetite is actually a natural protective mechanism of the body.

So it's really about framing it as allowing a natural death or A &D, which is the terminology replacing DNR in many clinical settings now, and this idea of protecting vulnerable patients.

It naturally extends to how we handle advanced directives across different specialty populations.

For instance, pediatrics.

The Affordable Care Act allows concurrent curative and hospice care for pediatric Medicaid patients.

But adolescents and young adults, the AYA population, they face a really unique psychological burden.

They do.

Because normal adolescent development is entirely focused on gaining independence and control.

A terminal illness just strips all of that away overnight.

So allowing AYA's to be actively involved in their own end -of -life planning, it helps them reclaim a crucial sense of autonomy.

We also have to be intensely aware of the LGBTQ plus population.

The medical trauma in this community is deep and very historical.

I mean, the American Psychiatric Association classified homosexuality as a mental illness all the way up until 1973.

And because of that history and ongoing discrimination, these patients often fear being judged or being outed to unsupportive biological family members, or worse, having their chosen families legally ignored in the ICU.

Which happens a lot.

It does.

So as a provider, you must ask for preferred pronouns and explicitly document their chosen health care power attorney, their HCPOA.

You have to ensure their legal rights are ironclad for when they can no longer speak for themselves.

The text also points out significant racial disparities here.

Black and indigenous populations are significantly less likely to have advanced directives.

You can't just hand a patient from a marginalized community a complex legal form and walk away.

You have to use culturally receptive community -based approaches to build trust before these conversations can even happen.

Absolutely.

Now, to actually facilitate any of these directives or hospice referrals, the primary care provider needs concrete data.

You have to objectively measure their physical decline.

Which brings us to the specific assessment tools you'll use in practice.

The first is the Palliative Performance Scale, or PPS.

It rates a patient's function from 0 to 100 % based on ambulation, activity, self -care, intake, and consciousness.

And the key number to remember there.

Right.

The text notes that if a patient's PPS score drops below 70%, that's your clinical trigger to start evaluating them for hospice appropriateness.

Perfect.

And for patients with advanced dementia who follow a very different trajectory, you use the FAST Scale, the Functional Assessment Staging Test.

It has seven stages.

So the FAST Scale for dementia is essentially charting developmental milestones in reverse.

That is an excellent way to conceptualize it.

Hitting that verse milestone of stage seven is critical.

Stage seven is characterized by profound loss.

We're talking vocabulary limited to about six words, incontinence, loss of ambulatory ability, and needing total assistance with all basic activities of daily living.

Hitting stage seven is your exact clinical trigger for a hospice evaluation in a dementia patient.

Okay, so once a patient is assessed and enrolled, the physical reality sets in, and your job as the MP shifts heavily to pharmacology.

It usually starts with the Hospice Comfort Pack, which is a literal kit the family keeps in their refrigerator.

Such a vital tool.

It's got liquid morphine, lorazepam, haloperidol, procloperazine, acetaminophen, and basacadil.

Let's talk about why we use these specific tools for what is arguably the most terrifying physical symptom, dyspnea or air hunger.

Dyspnea happens in up to 70 % of advanced cancer patients before death.

Management relies on the breathe's mnemonic.

B for bronchospasm, R for rails, E for effusion, A for anxiety, T for tachypnea, H for hemoglobin, E for educate, and S for sedate.

It's comprehensive.

It is, because you aren't just treating a feeling, you are treating the underlying mechanisms.

Take E for effusion.

As the heart and kidneys fail, fluid backs up into the pleural space around the lungs, basically crushing them.

And you can start with non -pharmacological interventions here, like a simple handheld fan blowing cool air on the face.

The mechanism there is fascinating.

It stimulates trigeminal nerve receptors, which sends a signal to the brain that eases the sensation of breathlessness.

It's simple, but highly effective.

But the heavy lifter for dyspnea is opioids.

And I want to pause and play the skeptical student again.

Wait, giving morphine to someone who is already struggling to breathe,

doesn't morphine naturally depress the respiratory drive?

It does.

But in a palliative context, depressing the respiratory drive is exactly the physiological mechanism we want.

Oh, interesting.

When a patient is experiencing air hunger, they take these racket, shallow, panicked breaths that don't actually exchange oxygen well at all.

A low -dose opioid slows that respiratory rate down, which allows for deeper, more effective breaths.

Plus, it directly blunts the brain's perception of breathlessness.

So you start with low -dose oral or sublingual morphine or hydromorphone.

And for students writing these prescriptions, remember your pharmacokinetics.

Subcutaneous opioids are twice as powerful as oral opioids.

So one milligram of oral hydromorphone equals 0 .5 milligrams subcutaneous.

Crucial math right there.

Very crucial.

You also have to manage coughs and terminal secretions.

For a severe cough, you might prescribe benzinatate.

But the text highlights a major safety warning here.

You must instruct the patient to swallow it whole.

Yes, do not chew it.

If they chew a benzinatate capsule, it releases a local anesthetic that numbs the entire throat and mouth.

And that can cause them to aspirate or even choke to death.

Definitely a red flag warning.

And regarding terminal secretions, which is often called the death rattle, the sound is terrifying for families, but you do not use oral suctioning.

Suctioning is invasive.

It causes microtrauma to the airway.

And it actually stimulates the body to produce even more secretions.

Instead, you reposition the patient.

You gently turn their head to the side so gravity helps clear the airway.

Pharmacologically, you dry the secretions up using anticholinergics.

Atropine drops administered sublingually or glycopyrrolate are the standard evidence -based choices.

But of course, treating the respiratory system with opioids inevitably causes massive problems down in the GI tract.

Right.

If you prescribe an opioid, constipation isn't just a possibility, it is an absolute inevitability.

Opioids fundamentally alter gut motility by delaying gastric emptying and literally constricting the pyloric sphincter.

Aggressive prevention is mandatory.

So you must prescribe a bowel regimen simultaneously with the opioid, every time.

You use osmotic laxatives like Meryl -LAX or stimulants like Senna and bisacredil.

And if the constipation is strictly opioid -induced and refractory to standard laxatives, then you step up to a targeted opioid receptor antagonist like methylnaltrexone, which is brilliant because it blocks the opioids effect in the gut without blocking the pain relief up in the brain.

Exactly.

You also have to manage nausea and vomiting.

The comfort pack includes indanzitron, prochlorperazine, and haloperidol.

Now haloperidol is a neuroleptic, but in palliative care, it's incredibly effective for chemical -induced nausea because it blocks dopamine receptors right in the brain's chemoreceptor trigger zone.

We also see profound anorexia and cachexia.

Cachexia is the involuntary metabolic loss of skeletal muscle.

You might trial medications like Magestral, dexamethasone, or the antidepressant mirtazapine to help stimulate appetite.

Now as the body's organs fail, the brain's chemistry alters dramatically, leading to severe neurological symptoms.

Delirium is incredibly common at the end of life, and it's highly under -recognized, particularly the hypoactive form.

Right, where the patient is just quiet, sleepy, and withdrawn, so providers miss it.

To manage delirium, the text says you first look for reversible causes, like polypharmacy, an undiagnosed UTI, or even just a full bladder causing systemic distress.

Always check the bladder.

Right.

If you absolutely need pharmacological management, the first -line treatment is a neuroleptic like haloperidol or dexamethasone.

What you do not use as a first -line treatment are benzodiazepines like lorazepam.

Why are benzos contraindicated for delirium?

Because benzodiazepines can cause paradoxical agitation in frail, elderly, or dying patients.

Instead of calming them down, it worsens the confusion and makes the delirium much more hyperactive and distressing.

This raises a really important clinical distinction, though.

How do you distinguish between medical delirium that needs treating and natural end -of -life visions?

Like, what does this all mean when you're standing in the room?

How do you actually tell a family that their loved one talking to a deceased spouse is normal and shouldn't be medicated away?

It requires immense empathy and, crucially, anticipatory guidance.

You explain the phenomenon to the family before it happens.

Setting expectations.

Exactly.

You tell them that, as the brain transitions, seeing deceased loved ones or feeling like they are packing for a journey is a deeply common, totally natural part of the dying process.

If the patient is peaceful and comforted by the vision, you normalize it.

You do not intervene.

You only use medication if the patient is severely distressed, fearful, or agitated by what they're experiencing.

That is such a vital distinction.

We also have to manage the sheer volume of pills a patient is taking.

Deprescribing is a daunting task, but it's critical to prevent falls and reduce that chemical burden on a failing liver and kidneys.

You use assessment tools like the STEDI algorithm, which stands for Stopping Elderly Accidents, Deaths and Injuries, or the Timed Up and Go test, the Tug test, to evaluate their fall risk and justify stripping away unnecessary medications like statins or vitamins.

Let's discuss the symptom patients and families fear most, pain.

For assessment, especially in advanced dementia patients who cannot verbally self -report their pain level, you use the PAIN -AID scale.

PAIN -AID stands for Pain Assessment in Advanced Dementia, and it relies on observing breathing, vocalization, facial expression, and body language.

For pain management, the rules of palliative pharmacology are very strict.

You administer medications around the clock, not just as needed.

You have to maintain a steady state of analgesia.

And you must calculate the rescue dose correctly.

The rescue dose for breakthrough pain should be 10 -20 % of the total 24 -hour scheduled dose.

Okay, let's do a quick mental math check out loud for the students.

Say my patient is taking 30 mg of long -acting oral morphine twice a day.

That's a 24 -hour total of 60 mg.

So my rescue dose of short -acting morphine should be 10 -20 % of that 60 mg, meaning I'd prescribe 6 -12 mg of immediate -release morphine every few hours for breakthrough pain.

You got it.

And when you need to titrate that baseline up because the disease is progressing, and remember, there is NO -sealing dose for opioids in terminal care.

You generally increase the 24 -hour total by 25 -50 % every one to two days.

Now the most dangerous math you will do is switching opioids.

Let's say your patient develops neurotoxicity to morphine, and you need to switch them to hydromorphone.

You calculate the equivalent dose using an Equianalgesic table.

Okay, walk me through this cross -tolerance safety rule.

If I calculate that the equivalent dose of a new opioid is 100 mg, I shouldn't just write a script for 100 mg, right?

Absolutely not.

Because of incomplete cross -tolerance, the patient's opioid receptors are used to the old drug, not the new one.

The new drug will bind much more efficiently and hit them much, much harder than the math suggests.

To be safe, you must reduce that calculated Equianalgesic dose by 25 -50%.

That reduced number is your safe starting dose.

So I'd start them at 50 -75 mg.

Yes.

Unless you are switching to methadone, methadone's half -life is incredibly long and it accumulates deep in the tissues over days.

If you are switching to methadone, you reduce the calculated equivalent dose by 90%.

Wow.

Reducing by 90 % is a massive safety prall for exams and practice.

It really is.

We should also mention that pain isn't just created with opioids.

The guidelines strongly support complementary non -pharmacological therapies.

Acupuncture has high -quality evidence per the NCCN for managing both pain and nausea.

Reiki, music therapy, guided imagery, massage, they all have measurable physiological benefits in reducing the patient's experience of total pain.

Alright, let's pull every single concept we've just discussed from pathophysiology all the way to cultural competence together and apply it to the textbook's exact closing case study to lock in that clinical reasoning.

Let's do it.

We have Anne, a 67 -year -old female with stage 4 breast cancer that has metastasized to the lung and liver.

She's in the primary care clinic complaining of shortness of breath.

Her oxygen saturation drops to 88 % on exertion.

She has mild pain with deep breathing and she tells the provider she's feeling blue.

She is accompanied by Cathy, whom she introduces as her roommate.

So applying the chapter's principles, the NP's first interventions must address the dyspnea.

You prescribe 2 liters of oxygen via nasal cannula and recommend a simple handheld fan to stimulate those trigeminal nerves.

Then you prescribe a microdose of 5 mg of liquid morphine.

And here the NP must directly address Anne and Cathy's immediate fears.

You explain the physiology that this microdose isn't going to cause addiction or stop her breathing, but it specifically treats the air hunger by slowing her respiratory rate so she can take deeper, more effective breaths.

You also address her blue mood.

You might introduce non -pharmacological dieted imagery or consider starting an antidepressant like mirtazapine, which could also help with any anorexia.

Finally, we apply the legal and cultural assessment.

The NP must identify Cathy as the healthcare power of attorney.

You secure the My5Wishes document in the most or polest form, explicitly instructing them to put it right on the refrigerator where EMS personnel are trained to look for it.

This perfectly ties back to what we discussed in the LGBTQ Plus segment and introduce Cathy as her roommate.

The provider uses affirming language, mirroring their terminology without judgment if they prefer roommate or partner, while proactively legally securing Cathy's rights.

Validating Cathy's role and securing her as the legal HCPOA isn't just paperwork.

It is a critical clinical intervention to prevent trauma and ensure Anne's wishes are honored when she can no longer speak.

It really is the ultimate synthesis of everything we've talked about today.

The hard science of symptom management seamlessly combined with the profound art of human connection.

Which brings us all the way back to where we started, that broken x -ray machine.

As advanced practice nurses, you spend your entire education learning how to fight disease, how to fix the broken bone, how to cure the infection.

But consider this.

When a cure is absolutely no longer possible,

true healing can still happen.

Providing a peaceful, well -managed, dignified death where a patient's pain is controlled, their breathing is eased, and their identity is respected.

That is one of the most profoundly successful healthcare outcomes you will ever facilitate in your career.

What a powerful way to reframe success in medicine.

To the NP and APRN students listening, thank you for trusting the last -minute lecture team here at the Deep Dive with your study prep.

Keep that empathy front and center in your clinicals, good luck on your exams, and we will catch you on the next Deep Dive.
