Prognostication and Disease Trajectories Flashcards

An 84-year-old male with NYHA Class IV heart failure has been hospitalized three times in the past four months for exacerbations. He is optimally treated with diuretics and vasodilators but remains symptomatic at rest. Which of the following is the strongest clinical indicator supporting a hospice-appropriate prognosis?

Answer: Persistent dyspnea and fatigue at rest

According to hospice eligibility guidelines, a key criterion for end-stage heart failure is persistent symptoms of recurrent heart failure (NYHA Class IV) at rest, despite optimal medical management. While a low ejection fraction is a factor, many stable patients live with an EF of 35%. A serum sodium of 137 mEq/L is within normal limits, and +1 pedal edema is a mild finding.

Which of the following disease trajectories is most commonly associated with advanced organ failure, such as end-stage COPD or congestive heart failure?

Answer: A long-term limitation with intermittent, serious, and life-threatening exacerbations

The classic trajectory for end-stage organ failure is one of a low baseline of function punctuated by acute, severe exacerbations. Patients may recover from these episodes, but often to a lower functional baseline, until a final exacerbation becomes fatal. This is distinct from the more predictable, steep decline in cancer (A) or the slow, progressive dwindling of frailty or dementia (B).

An ACHPN is using the Functional Assessment Staging Tool (FAST) to evaluate a patient with advanced Alzheimer's disease. The patient has recently lost the ability to speak more than five or six intelligible words per day. According to the FAST scale, this finding places the patient in which stage, which is a key marker for a life expectancy of six months or less?

Answer: Stage 7a

Stage 7 of the FAST scale details the severe functional decline in late-stage Alzheimer's. Stage 7a is specifically defined by the ability to speak being limited to approximately 5-6 intelligible words a day. This milestone is a critical indicator used to establish hospice eligibility, as it correlates with a prognosis of six months or less.

The Palliative Performance Scale (PPS) is a widely used tool for prognostication. A patient who spends the majority of their day sitting or lying down, has extensive disease, and requires considerable assistance with most personal care would most likely be assigned which PPS level?

Answer: 50%

A PPS score of 50% is defined by characteristics including spending the majority of the day sitting or lying down ('mainly sit/lie'), having extensive disease, and requiring considerable assistance for most self-care. A score of 70% describes a patient with reduced ambulation who can still manage most of their own care, while 30% describes a patient who is totally bedbound and requires total care.

An ACHPN is evaluating an 88-year-old patient with metastatic lung cancer who has been declining rapidly. Which of the following clinical signs is the most reliable predictor of a prognosis of weeks to a few months?

Answer: A Karnofsky Performance Status (KPS) score of 30%

While all listed signs indicate decline, a profound drop in functional status, as measured by a validated tool like the Karnofsky Performance Status (KPS), is one of the most robust predictors of short-term prognosis. A KPS score of 30% indicates a patient is severely disabled and requires hospitalization or equivalent care, which is strongly associated with a prognosis of weeks to a few months. The other signs are common in the dying process but are less precise for timing the prognosis.

A 75-year-old patient with severe COPD has a BODE index score of 9. The ACHPN recognizes that this score indicates which of the following regarding the patient's prognosis?

Answer: A high risk of mortality, with an approximate 4-year survival rate of only 20%

The BODE index (Body-mass index, airflow Obstruction, Dyspnea, and Exercise capacity) is a validated prognostic tool for COPD. A score of 7-10 places a patient in the highest risk quartile, which is associated with high mortality. A score of 9 specifically correlates with an approximate 80% mortality rate at 52 months (roughly 4 years), meaning about a 20% survival rate. This poor prognosis supports a focus on palliative care rather than aggressive, curative therapies.
