palliative care

whole-person care for people with serious illness

whole-person care

holistic care that addresses well-being as defined by individuals, their families, and communities

no

should you wait until heart failure stage D for palliative care?

mortality and rehospitalizations

what does palliative care NOT change?

treat underlying cause, palliate

symptom management approach in serious illness

drug side effect

any symptom in an older adult should be considered a ______ until proved otherwise

NSAIDs

what is the most common cause of uncontrolled (and reversible) dyspnea in heart failure

decompensation, death, increase in systolic blood pressure and MAP

what do systemic NSAIDs increase risk of?

NSAIDs cause vasoconstriction of the afferent arteriole, which increases sodium and fluid retention

how do systemic NSAIDs worsen dyspnea in heart failure?

NSAIDs constrict the afferent arteriole, which leads to reduced glomerular pressure, which causes an acute kidney injury

how do systemic NSAIDs cause acute kidney injury?

NSAIDs prevent aspirin from binding to COX-1, making aspirin ineffective

how do NSAIDs affect antiplatelets when administered together?

increase risk of GI bleeding

what risk does NSAIDs and anticoagulants have when administered together?

life expectancy, values, preferences
