Would I be surprised if this patient died in the next 6-12 months?
General indicators >1

If not surprised and patient has general and disease-specific criteria – patient benefits from palliative approach
Talk tip: “We can’t cure your disease, but our goal is to help you live as well as you can for as long as you can.”
Talk tip: “Although we do not have any further treatments to reverse the disease there is always something we can do to help you feel better.”
Common symptoms of advanced disease
Using the scale, evaluate each of following symptoms: (0=none, 10=worst possible)
- Shortness of breath/dyspnea
- Lack of appetite/anorexia
Note about pain assessment:
- identify site(s), causes, severity, and impact on function, mood and quality of life.
- pain is a physical and emotional experience and can be influenced by multiple other factors.
Note about shortness of breath/dyspnea assessment: it CANNOT be assessed by the respiratory rate or the oxygen saturation. Like pain – it is subjective. Ask patient if they feel short of breath.
Talk tip: if the patient has many symptoms, ask which symptom is bothering them the most, and manage that symptom as the top priority.
CAM tool for Delirium Assessment
The Confusion Assessment Method (CAM) enables you to determine if your patient has delirium. A diagnosis of delirium requires:
- acute onset and fluctuation
- disorganized thinking or altered consciousness
Acute onset and fluctuation
Is there evidence of an acute change in mental status from baseline?
Does the abnormal behaviour:
- come and go
- fluctuate during the day
- increase/decrease in severity
Does the patient:
- have difficulty focusing attention?
- become easily distracted?
- has difficulty keeping track of what is said?
Is the patient’s thinking disorganized or incoherent, i.e. does the patient have:
- rambling speech or irrelevant conversation?
- unpredictable switching of subjects?
- unclear or illogical flow of ideas?
Overall, what is the patient’s level of consciousness:
- alert (normal)
- vigilant (hyperalert)
- lethargic (drowsy but easily roused)
- stuporous (difficult to rouse)
- comatose (unrousable)
Don’t forget hypercalcemia
- 10% of cancer patients (50% of multiple myeloma, 25% breast, 25% lung, renal)
- Due to osteoclast destruction of bone secondary to bone metastases
- Paraneoplastic production of PTH in non-solid tumors – leukemia, lymphoma
- Common cause of hypoactive delirium
- Sign of advanced disease, BUT treatment can improve quality and length of life
- Symptoms: polyuria, polydipsia → dehydration, nausea, constipation, confusion, drowsiness, weakness,
- Signs: hyporeflexia, ileus, bradycardia, Q-T interval reduced <0.36 sec, T wave abrupt upslope
- Diagnosis: serum calcium (corrected for albumin) > 2.8mmol/L or > 11mg/dl (Corrected Ca+2 = Measured Ca+2 + (40 – serum albumin) X 0.02)
