The Final Days Keeping the Promise of Comfort Mike Harlos MD, CCFP(PC), FCFP Professor and Section Head, Palliative Medicine, University of Manitoba Medical Director, WRHA Adult and Pediatric Palliative Care http://palliative.info Objectives By the end of this presentation, participants will be able to: • understand the common clinical challenges as death nears due to progressive illness • be aware of common concerns of families as death nears • describe the management of dyspnea, delirium, and congestion in the final days of life There are no “do-overs” in managing a death End of life can arise… Sudden, immediate death (seconds/minutes) – little opportunity for anticipating & managing symptoms Not so sudden/immediate – potential for anticipating and addressing “threats to comfort” Progressive illness • cancer • neurodegenerative illness • end-stage organ failure Acute Event • severe brain injury (CVA, anoxia, trauma) • sepsis • inoperable surgical conditions Final common pathway • bedridden • weak, swallowing impaired, poor airway protection, can’t clear secretions; pneumonia – dyspnea, congestion • delirium – agitation Predictable Challenges As Death Nears In Progressive Terminal Illness • Functional decline – 100% • Compromised oral intake (food, fluids, meds) –100% - Families concerned about this – pretty much 100% • Congestion: reported as high as 92% • Dyspnea: 80% + as death nears • Delirium: 80% + When these issues arise at end-of-life, things haven’t “gone wrong”… they have gone as they are inclined to Role of the Health Care Team 1. Anticipate changes and challenges 2. Communicate with patient/family regarding potential concerns: What can we expect? What are the options? Not eating/drinking; sleeping too much How do we know they are comfortable? Are medications making things worse? Would things be different in a different care setting? 3. Formulate a plan for addressing predictable issues, including: Health Care Directive / Advance Care Plan / LAD (if at home) Medications by appropriate routes for potential symptoms Clinical Considerations As Death Nears 1. Preexisting medical conditions needing attention? • not usually necessary to continue ongoing medical management of underlying illnesses, with the possible exception of seizure disorder 2. Potential new symptoms – typically dyspnea, congestion, agitated delirium • Pain not commonly new/escalating in final hrs • Anticipate loss of oral route 3. Anticipated concerns of family Medications Most Commonly Needed 1. Opioid: pain, dyspnea 2. Antisecretory: congestion 3. Sedative (antipsychotic +/- benzodiazepine): agitated delirium Plus whatever condition-specific medications are needed (e.g. anticonvulsants) Management of Symptoms Symptom Drug Non-Oral Route(s) Dyspnea opioid • sublingual (SL) – small volumes of high concentration; same dose as oral • subcutaneous – supportable in most settings; same dose as IV = ½ po dose • IV – limited to hospital settings • intranasal – fentanyl – lipid soluble opioid; use same dose as IV to start • Note: Transdermal not quickly titratable Pain opioid see above scopolamine Secretions glycopyrrolate Agitated Delirium antipsychotic (methotrimeprazine; haloperidol) lorazepam • subcutaneous • transdermal (patches; compounded gel) • subcutaneous • SL– use same dose for all routes • subcutaneous (most settings); IV (hospital) • SL – generally use with neuroleptic Dyspnea In The Palliative Patient • subjective experience of breathing distress rather than an observation of increased work of breathing o i.e. it is something experienced rather than diagnosed • many causes (infection, anemia, pulm. embolism, hemorrhage, tumour infiltration/obstruction, etc.) • increasing incidence as death nears; can escalate quickly • in non-verbal patients, typically look for increased work of breathing plus signs of distress (frightened appearance, grimacing, restlessness) • severe dyspnea in advanced terminal illness usually portends an imminent death Approach To Dyspnea In The Final Hours/Days • if clinically feasible and consistent with goals of care, consider addressing potentially reversible causes (uncommon if death is imminent) • might be helped by repositioning, using a fan, open window (cool air) • supplemental O2 – questionable role; depends on context • opioids are main pharmacological intervention • anxiolytics may have a role if there is a strong anxiety component Role of O2 In Palliative Patients • not a straightforward issue • supplemental O2 may prolong the natural dying process • the awake hypoxic patient feels less dyspnea with O2 o often nasal prongs are better tolerated than mask, regardless of oximetry • the unconscious/comatose patient does not likely experience air hunger – consider discussing tapering supplemental O2 Opioids in Dyspnea • Uncertain mechanism • Comfort achieved before resp compromise; rate often unchanged • Often patient already on opioids for analgesia; if dyspnea develops it will usually be the symptom that drives the need for titration • Dosage should be titrated empirically • May need rapid dose escalation in order to keep up with rapidly progressing distress Opioid Use in Final Days/Hours • doses depend on degree of distress, existing opioid tolerance • short-acting opioid in order to respond quickly to changing symptoms (e.g. dyspnea) • if patient is on transdermal fentanyl, consider leaving this as is, and adding short-acting morphine or hydromorphone, titrating to effect • the effect of a prn (as-needed) dose will be evident by 1h by all routes. The interval between prn doses should not exceed one hour – a longer interval will cause needless suffering Common Concerns About Aggressive Use of Opioids at End-Of-Life • How do you know that the aggressive use of opioids doesn't actually bring about or speed up the patient's death? • “I gave the last dose of morphine and he died a few minutes later… did the medication cause the death?” 1. Literature: the literature supports that opioids administered in doses proportionate to the degree of distress do not hasten death and may in fact delay death 2. Medication history: usually “the last dose” is the same as those given throughout recent hours/days, and was well tolerated 3. Clinical context: breathing patterns usually seen in progression towards dying (clusters with apnea, irreg. pattern) vs. opioid effects (progressive slowing, regular breathing; pinpoint pupils) Changes not related to opioids… Cheyne-Stokes Rapid, shallow “Agonal” / Ataxic In circumstances of excessive opioid dosing, there is virtually always as associated clinical context (aggressive medication titration, complex opioid conversions) and the following physical signs: • pinpoint pupils • gradual slowing of the respiratory rate • breathing is deep (may be shallow) and regular Congestion in the Final Hours ("Death Rattle”) • Positioning • ANTISECRETORY: − scopolamine 0.3-0.6 mg subcut q2h prn − glycopyrrolate 0.2-0.4 mg subcut q2h prn (less sedating than scopolamine) − 1% atropine ophthalmic drops (1-2 drops) administered SL/buccally may reduce oral secretions but not likely pulmonary congestion • Might consider suctioning if secretions are distressing, proximal, accessible, and not responding to antisecretory agents Irreversible Agitated Delirium At End-of-Life • should be considered a medical emergency due to profound impact on quality of life, dignity, family experience and memories of the death What Makes An End-of-Life Delirium Irreversible? 1. Clinical factors: no treatment options available; rapid time course 2. Directive from patient/proxy that no further investigations be done and that interventions focus strictly on comfort 3. Limitations of care setting – e.g. remaining at home Considerations Regarding Aggressive Sedation ● Meds titrated to effect… the correct dose is “the one that works” within acceptable adverse effects, and is proportionate to the distress ● Tend to use a antipsychotic +/- benzodiazepine; subcutaneous route is most common, but can use SL ● Methotrimeprazine (Nozinan®) commonly used; others include olanzapine, haloperidol ● Can add a benzodiazepine such as sublingual lorazepam ● Commonly need regular intermittently scheduled doses (e.g. q4h or q6h) plus a prn dose of q1h prn ● prn medication orders must allow “stacking” doses… i.e. repeating a dose if needed by the time it should have worked (typically an hour would be the longest time) Examples of Sedation Orders in Final Hours Note: • these are conservative starting doses… may need higher • some patients may just need prn dosing ● Antipsychotics methotrimeprazine (Nozinan®) 2.5 – 5 mg subcut/SL q4-8h regularly plus q1h prn haloperidol 0.5 -1 mg subcut/SL q6-8h regularly plus q1h prn ● Benzodiazepines (not recommended for use without neuroleptic; may exacerbate agitated delirium) lorazepam 0.5 – 1 mg SL q4-6h plus q1h prn Supporting Families ● effective sedation changes the beside dynamics from one in which people are afraid to visit and there is no meaningful interaction to one in which people can talk, read, sing, play favourite music, pray, tell stories, touch. ● Health care team has a role in facilitating meaningful visits… family/friends may not know “the right things to do” ● Individuals may want time alone but be reluctant to ask others (friends/family) to leave the room. The health care team can suggest that this might be something that the family can explore with each other Supporting Families With Regards To Sedation ● effective sedation can allow families to talk, read, sing, play music, pray, tell stories, etc. without causing agitation. ● health care team has a role in facilitating meaningful visits… family/friends may not know “the right things to do” ● individuals may want time alone but be reluctant to ask others (friends/family) to leave the room. The health care team can suggest that this might be something that the family can explore with each other ● can they hear us? • family must be aware that the patient is not likely to be both awake and calm/settled again • preemptively address potential concerns (family and staff) that the sedation is speeding up or contributing to the dying… perhaps more so when continuous infusions are used • This concern may not be overtly expressed, however it is important enough to strongly consider preemptive discussions “Sometimes people wonder if the medications are speeding things up, and contributing to the dying process… is that something that you had wondered about? Would it be helpful to talk about that?” The literature indicates that proportionate palliative sedation does not hasten the dying process when death is imminent due to the underlying condition1- 4 1.

Helping Families At The Bedside • physical changes – cyanosis; breathing patterns • how do you know they’re comfortable? • missed the death Displacing the Decision Burden “If he could come to the bedside as healthy as he was a month ago, and look at the situation for himself now, what would he tell us to do?” Or “If you had in your pocket a note from him telling you that to do under these circumstances, what would it say?” Life and Death Decisions? • Families may feel as though they are being asked to decide whether their loved one lives or dies – i.e. to choose life/death • It may help to remind them that the underlying illness itself is not survivable – no decision they make can change that “I know that you’re being asked to make some very difficult choices about care, and it must feel that you’re having to make life-and-death decisions. You must remember that this is not a survivable condition, and none of the choices that you make can change that outcome. We know that his life is on a path towards dying… we are asking for guidance to help us choose the smoothest path, and one that reflects an approach consistent with what he would tell us to do.” The Temptation of Treatability • In general, people do not die of the underlying lifelimiting condition, but from its complications – pneumonia; sepsis; bleeding; organ failure; etc. • Families may say “We know he is going to die from his cancer, but we can’t just let him die from pneumonia – people don’t die from pneumonia these days” • You can find yourself being drawn by the “temptation of treatability” into a course of micromanaging the dying process that would have otherwise unfolded naturally, predictably, and usually calmly Palliative Sedation (Sedation for Palliative Purposes) Sedation for Palliative Purposes is the planned and proportionate use of sedation to reduce consciousness in an imminently dying patient, with the goal to relieve suffering that is intolerable to the patient and refractory to interventions acceptable to the patient Palliative Sedation (Sedation for Palliative Purposes) Sedation for Palliative Purposes is the planned and proportionate use of sedation to reduce consciousness in an imminently dying patient, with the goal to relieve suffering that is intolerable to the patient and refractory to interventions acceptable to the patient The intention of the intervention is to sedate, rather than sedation being the undesired yet predictable side effect of medications such as opioids or antinauseants Palliative Sedation (Sedation for Palliative Purposes) Sedation for Palliative Purposes is the planned and proportionate use of sedation to reduce consciousness in an imminently dying patient, with the goal to relieve suffering that is intolerable to the patient and refractory to interventions acceptable to the patient Medications are titrated to the lowest effective dose. Respiratory rate and pattern are watched to prevent medication-related resp. depression Palliative Sedation (Sedation for Palliative Purposes) Sedation for Palliative Purposes is the planned and proportionate use of sedation to reduce consciousness in an imminently dying patient, with the goal to relieve suffering that is intolerable to the patient and refractory to interventions acceptable to the patient Expected natural death within 1-2 weeks from the underlying life-limiting condition, to avoid hastening the death through dehydration caused by prolonged sedation Palliative Sedation (Sedation for Palliative Purposes) Sedation for Palliative Purposes is the planned and proportionate use of sedation to reduce consciousness in an imminently dying patient, with the goal to relieve suffering that is intolerable to the patient and refractory to interventions acceptable to the patient The person experiencing the suffering is in the best position to judge “intolerable” Palliative Sedation (Sedation for Palliative Purposes) Sedation for Palliative Purposes is the planned and proportionate use of sedation to reduce consciousness in an imminently dying patient, with the goal to relieve suffering that is intolerable to the patient and refractory to interventions acceptable to the patient Proposed interventions may seem minor or trivial to the health care team, but unduly burdensome to the patient
