A 76-year-old woman is brought to the physician by her daughter for evaluation of progressive cognitive decline and a 1-year history of incontinence. She was diagnosed with dementia, Alzheimer type, 5 years ago. The daughter has noticed that in the past 2 years, her mother has had increasing word-finding difficulties and forgetfulness. She was previously independent but now lives with her daughter and requires assistance with all activities of daily living. Over the past year, she has had decreased appetite, poor oral intake, and sometimes regurgitates her food. During this time, she has had a 12-kg (26-lb) weight loss. She was treated twice for aspiration pneumonia, and her diet mainly consists of pureed food. She has no advance directives, and her daughter says that when her mother was independent, she mentioned that she would not want any resuscitation or life-sustaining measures if the need arose. The daughter wants to continue taking care of her mother but is concerned about her ability to do so. The patient has hypertension and hyperlipidemia. Current medications include amlodipine and atorvastatin. Vital signs are within normal limits. She appears malnourished but is well-groomed. The patient is oriented to self and recognizes her daughter by name, but she is unaware of the place or year. Mini-Mental State Examination score is 17/30. Physical and neurologic examinations show no other abnormalities. A complete blood count and serum concentrations of creatinine, urea nitrogen, TSH, and vitamin B12 are within the reference range. Her serum albumin concentration is 3 g/dL. Urinalysis shows no abnormalities. Which of the following is the most appropriate next step in management?
A. Short term rehabilitation
B. Prescribe oxycodone
C. Home hospice care
D. Insert feeding tube
E. Inpatient palliative care
This patient has already had advanced dementia (as indicated by her speech problems, total functional dependence, food regurgitation, and incontinence) for at least 1 year. Given that the average life expectancy after the onset of severe dementia is < 18 months, the patient’s estimated life expectancy is likely < 6 months
Answer: C
This patient is malnourished, has advanced Alzheimer dementia, and is almost completely dependent on all activities of daily living. Onset and progression of feeding difficulties is a hallmark of advanced dementia and indicates a poor prognosis. Considering that her life expectancy is likely under 6 months, she qualifies for hospice care. While this patient lacks decision-making capacity at this time, she expressed that she would not want resuscitation or life-saving procedures in the past, which constitutes another indication for hospice care for this patient.
For anaemic pallitiave patient, if Hb <____g/dL, and symptomatic, consider transfusion.
If Hb <10 g/dL and symptomatic Treat any reversible cause (e.g. iron deficiency, GI bleeding 2° to NSAIDs). Consider transfusion
If transfused Record whether any benefit is derived (as if not, further transfusions are futile) and the duration of benefit (if <3 wk—repeat transfusions are impractical). Monitor for return of symptoms; repeat FBC and arrange repeat transfusion as needed
Hypercalcaemia occurs with which malignancies?
10% malignant tumours—> particularly myeloma (>30%) and breast cancer (40%).
Management of hypercalcaemia
Depending on the general state of the patient, make a decision whether to treat the hypercalcaemia or not.
If a decision is made not to treat, provide symptom control and do not check the serum calcium again.
Hypercalcaemia can be fatal. if Ca2+ >3.5mmol/L or severe Sx, admit for lowering of Ca2+ with forced diuresis + IV biphopshonate
see p.336
For diagnosis of cause of hypercalcaemia:

Alk phos high
It could suggest _____
bone metastases
sarcoidosis
thyrotoxicosis
For diagnosis of cause of hypercalcaemia:
if albumin level normal/ low,
phosphate high/ normal,
Alk phos normal

A 65-year-old man is admitted to the hospital because of a 1-month history of fatigue, intermittent fever, and weakness. Results from a peripheral blood smear taken during his evaluation are indicative of possible acute myeloid leukemia. Bone marrow aspiration and subsequent cytogenetic studies confirm the diagnosis. The physician sets aside an appointed time-slot and arranges a meeting in a quiet office to inform the patient about the diagnosis and discuss his options. He has been encouraged to bring someone along to the appointment if he wanted. He comes to the office at the appointed time with his daughter. He appears relaxed, with a full range of affect. Which of the following is the most appropriate opening statement in this situation?
A. “I may need to refer you to a blood cancer specialist because of your diagnosis. You may need chemotherapy or radiotherapy, which we are not equipped for.”
B. “Your lab reports show that you have an acute myeloid leukemia”
C. “What is your understanding of the reasons we did bone marrow aspiration and cytogenetic studies?”
D. “Would you like to know all the details of your diagnosis, or would you prefer I just explain to you what our options are?”
E. “You must be curious and maybe even anxious about the results of your tests.”
C.
When delivering bad news, physicians should follow the SPIKES protocol.
- creating an appropriate SETTING;
- addressing the patient’s PERCEPTION of his/her situation;
- seeking the patient’s INVITATION;
- giving KNOWLEDGE to the patient regarding diagnosis and prognosis;
- addressing the patient’s EMOTIONS;
- providing a management STRATEGY and SUMMARY of what had been discussed so far.
Mangement for Deep gnawing pain that is Worse on moving/weight bearing in palliative care
This is bone pain
Try NSAIDs and/or strong opioids
Consider referral for palliative radiotherapy, strontium treatment (prostate cancer), or IV bisphosphonates (decrease pain in myeloma, breast, and prostate cancer)
Refer to orthopaedics if any lytic metastases at risk of
fracture, for consideration of pinning
For sharp ache pain in the abdominal area that is worse on bending or breathing, what’s the management?
For Burning/shooting pain associated with altered sensation, what’s the management?
for rectal pain, what’s the management?
for muscle pain, what’s the management?
for bladder pain or spasm, what’s the management?
For pain of short duration e.g. from dressing changes, what’s the management?
try a breakthrough dose of oral duration morphine 20min prior to the procedure
A 78-year-old man with stage IV non-small cell lung cancer is admitted to the hospital for palliative care because of a 2-day history of severe bone pain and insomnia. He has not received opioid medications in the past. Treatment with intravenous morphine via a patient-controlled pump is initiated. Twelve hours later, the patient says, “The pain is still unbearable, please do something or help me sleep forever. I can’t do this anymore.” His temperature is 37.0°C (98.6°F), pulse is 106/min, respirations are 21/min, and blood pressure is 142/72 mm Hg. Examination shows shallow breathing. The patient-controlled analgesia system is checked and found to be functioning properly. Which of the following is the most appropriate next step in management?
A. Increase morphine dosage as needed for pain control
B. Change morphine to a nonopioid analgesic and add zolpidem for insomnia
C. Remove the patient-controlled pump immediately to prevent intentional morphine overdose
D. Continue morphine therapy at the same dosage to avoid respiratory depression
E. Request psychiatric evaluation to assess for suicidal ideation
The shallow but rapid breathing, insomnia, and features of sympathetic activation (e.g., tachycardia, hypertension) are most likely due to pain. For terminally ill patients, pain relief is prioritized over the potential adverse effects of pain medication (i.e., the principle of double effect).
Answer: A
This patient’s severe, persistent pain indicates that he is currently not receiving an adequate dosage of morphine. Under close monitoring, a titrated increase in opioid dosage (typically by 25–50% every 24 hours until the desired pain relief is achieved) minimizes the risks of severe side effects (e.g., respiratory depression). For individuals on patient-controlled analgesia, this dosage titration can be achieved by decreasing the duration of the lockout period, increasing the single bolus limit, and/or increasing the daily dose limit of the opioid. In addition, a continuous low-dose infusion of opioids or nonopioid analgesics can be used as an adjuvant for pain relief.
A 78-year-old man receiving home hospice care for advanced metastatic prostate cancer is examined at home at the request of his wife. He was diagnosed with prostate cancer 10 months ago, and the cancer has metastasized to his lower spine, pelvis, right femur, liver, and lungs despite hormonal ablation therapy. The patient declines chemotherapy. His wife reports difficulty managing her husband’s pain and that he is restless. He has avoided solid food for the past 2 weeks and has lost weight. He often coughs after drinking water. Current medications include extended-release morphine, acetaminophen, oxycodone as needed, and lactulose. The patient appears to be in moderate distress. Temperature is 37.9°C (100.2°F), pulse is 102/min, respirations are 24/min, and blood pressure is 121/85 mm Hg. Physical examination shows decreased skin turgor and dry mucous membranes. Cardiopulmonary examination shows no abnormalities. There is severe tenderness to palpation of the lower back, and the patient is unable to sit up on his own due to pain. Which of the following is the most appropriate next step in management?
A. Schedule external beam radiation therapy
B. Prescribe a transdermal fentanyl patch
C. Prescribe diazepam for the evenings
D. Prescribe codeine for the evenings
E. Have the patient crush his morphine pills and take them with soft foods
Answer: B
This patient is in distress due to insufficiently controlled pain, and he has dysphagia. Accordingly, his oral medications should be reduced as much as possible, and a non-oral form of analgesia is the most appropriate next step in management. Fentanyl is a synthetic full opioid agonist with a higher potency than morphine. The transdermal formulation of fentanyl is indicated in the treatment of chronic pain, providing steady analgesia because it diffuses continuously into the blood.
TIP:
This terminally ill patient has insufficient pain control, as evidenced by his restlessness, tachycardia, and tachypnea.
Management of cough and breathlessness, general durg measures:
Management of anxiety in palliative care, drug wise:
Management of depression in palliative care, drug wise:
Management of Excessive respiratory secretion (death rattle)
Management of terminal breathlessness
Management of terminal restlessness
