This document provides guidance for healthcare professionals on determining a terminal prognosis and accessing hospice care. It discusses the challenges of prognosis, general clinical criteria like functional status and symptom burden, and disease-specific guidelines for predicting prognosis in cancers, end-stage cardiac or pulmonary disease, dementia, cerebrovascular disease, liver disease, HIV/AIDS, and end-stage renal disease without dialysis. Key points are that prognosis involves clinical judgment of multiple factors, physicians tend to overestimate survival, and guidelines provide population-level rather than individual predictions.
2. Goal
To educate healthcare professionals about the
challenges of end-of-life care specifically when
determining a terminal prognosis, so that they
can assist, support and provide the optimum
care for the patient and family during the
final stages of life
3. Objectives
• Understand the challenges for patients, families and
healthcare providers in accessing hospice care
• Understand the Theoretical Trajectories of Dying
• Describe the General Guidelines for Clinical
Progression of Disease
• Describe the basic criteria for determining prognosis in
patients with various cancers
• Detail the clinical criteria for a number of end stage
(ES) non-cancer diseases
4. Reflections about Prognosis
• Cornerstone to clinical decision-making
– Elicit goals through shared decision-making
– Plan of care
• Multiple domains
– Remaining life expectancy
– Functional status, social status
• Inherent uncertainty
• Physicians are bad at it
– No clinical training
– In general overestimate everything
– Takes time and no reimbursement
Glare et al. Journal of Palliative Medicine 2008;11(1): 84-103
5. Science of Prognosis
• “Accurate” estimates of prognosis for a
population with a specific disease
• Increased “noise” as we attempt to estimate
the prognosis for an individual
• Further challenges with comorbidity
Stockler et al. Br. J Cancer, 2006;94(2):208-212

Weight loss represents a key determinant of a poor prognosis which is readily obtainable for no significant additional cost. Two studies that demonstrate this point are highlighted on the slide. The first study looked at long-term care residents who did and did not have a weight loss of at least 5% in the preceding month. Those residents who lost 5% weight in 1 month were 5 times more likely to die compared to those who did not lose that much weight over the ensuing year. The second study examined weight loss (5% of body weight in last 6 months) among community-dwelling outpatients in Palo Alto California. Importantly, 35% of the sample had no identifiable cause of weight loss even after extensive evaluation. Among patients with weight loss, 25% had died over the ensuing year.
This is one of many studies that demonstrates the relationship of PPS with mortality. The lower the PPS the higher the mortality. The graph displayed demonstrates survival among a cohort of 277 patients evaluated on the Pain and symptom consult service at UNC. Importantly, a PPS of 50 is associated with a 50% survival around 180 days whereas a PPS of 10% has a 50% survival of days. Similar findings between PPS score and mortality have been found in hospice populations.
Again, ADL impairment is highly correlated with mortality and the greater the number of ADL impairments the greater the mortality. This is displayed in the slide were you can see the relationship between ADL difficulty and survival by cox-proportional hazzard modeling. In this study of nationally representative community-dwelling older adults those with no ADL impairment lived on average 10.6 years compared to those with complete ADL impairment who lived an average of 1.6 years after taking into account age, gender, ethnicity, and comorbid conditions. A little later we will examine the relationship between ADL loss surrounding a hospitalization and subsequent mortality to further emphasize this point.
ADL=0 no difficulty- eat, toilet, bathe, and walk without difficulty
ADL=1 Mild difficulty-
ADL=2 moderate difficulty
ADL 3=severe difficulty
ADL IV complete difficulty
Older adults commonly fall and recurrent falls put older adults at an increased risk of dying. The relationship between fallers and non-fallers is displayed on the slide derived from community swelling older adults in Alabama. A cohort of 125 community dwelling older adult fallers were matched to other community dwelling older adults and differences in survival were compared. As you can see from the graph, fallers were significantly more likely to die compared to non-fallers with 25% of those who fell dying over the next year. The cause of death is also listed and it is important to recognize that many of the conditions may not readily be attributable to a fall which re-enforces the point that falls often serve as a proxy of underlying disease severity.
Another important contributor to functional decline is cognition. Cognitive decline commonly occurs with the progression of chronic illness such as CHF, COPD, and cancer independent of whether or not an underlying dementia is present. Cognitive status can quickly be assessed by ascertaining orientation, wakefulness, ability to communication and interaction with the environment. A more comprehensive assessment of cognitive status is the Folstein mini-mental status exam which was developed as a measure of overall global cognitive function. Cognitive performance ranges from 30 to 0 with higher scores indicating better cognitive function. Overall performance can be used to categorize cognitive functioning into intact, mild impairment, moderate impairment, and severe impairment. We are going to go over the MMSE since some programs routinely use the measure and it is commonly scored incorrectly.
Health care utilization is also a powerful predictor of subsequent mortality among older adults. Increased health care utilization is commonly used to help demonstrate a patient’s prognosis is 6 months or less with hospitalization being the most commonly studied. The slide indicates the health care utilization of out patient KP over the past 6 months. On the next slide we will look at the relationship between ADL decline during a hospitalization and subsequent mortality.
The slide displays the results of a study that examined the relationship between recovery of ADL loss during a hospitalization and subsequent ongoing decline or death. For example, at 6 months, the group of patients that had no ADL decline surrounding an index hospitalization found 11% had died, 15% had developed functional decline, and 74% had maintained functional abilities. On the other hand, patients who experienced functional decline in ADL’s during the hospitalization found almost 33% had died, 34% had additional ADL decline, and only 36% maintained the level of ADL at hospital discharge. Of note, 41.3% of patients hospitalized and had functional decline were dead 1 year later.
The last indicator of functional status we are going to discuss today is symptoms. Many studies from different disease states demonstrate the relationship between uncontrolled symptoms and subsequent mortality. For example, in patients with CHF shortness of breath or fatigue with minimal exertion (NYHA class III) or at rest (NHYA class IV) with optimal medical management support a prognosis of 6 months or less and hospice appropriateness. As a result, a patient’s assessment should incorporate how physical and psychological symptoms are associated with or impacting the patient’s decline. For example, nausea has lead to reduced oral intake and contributed to the 10% weight loss.
One of the most common symptoms that present in hospice appropriate patients is delirium. Delirium is an acute state of confusion with poor attention that fluctuates over the course of the day and may or may not be associated with hallucinations. Delirium is a predictor of poor prognosis as demonstrated on the following slide.
The slide displays the findings of an observational cohort study in Canada in which hospitalized patients with (243) and without (118) delirium were followed after hospital discharge. Patients with delirium at the time of hospital discharge had a 12 month mortality rate of 41.6% compared to 14.4% among patients discharged without delirium. The study demonstrates the significantly increased risk of mortality when delirium is present.

Information about prognosis for patients with very advanced heart failure in an era of more sophisticated heart-failure therapies is available from several recent studies. The Randomized Evaluation of Mechanical Assistance for the Treatment of Congestive Heart Failure (REMATCH) study was a randomized controlled trial of destination LVAD versus optimal medical management (OMM) for patients with inotrope-dependent Class III or Class IV heart failure. Sixty-one patients were enrolled in the OMM arm of the study. Their mortality was 50% at 6 months, 75% at 12 months, and almost 100% at 2 years. The Continuous Outpatient Support with Inotropes (COSI) study followed 36 patients on home inotropic support. Mortality for these patients was 60% at 6 months and 94% at 1 year. Multiple randomized controlled trials comparing CRT with OMM have been published.324,328 In the Comparison of Medical Therapy, Pacing, and Defibrillation in Heart Failure (COMPANION) study, 308 patients with Class III or IV heart failure and EF lower than 35% were enrolled in the OMM arm. Twenty-five percent of these patients died during the 12-month study period.320
Clinical sample of patients recruited from an inpatient hospital stay and followed over several years. 35-50% CHF admits secondary to diastolic dysfunction. No difference in survival from those with diastolic and systolic dysfunction. In diastolic dysfunction functional status a big predictor of survival. Simial rates of hospitalization as well
Another study I always like to highlight to further demonstrate this point is displayed on the slide. Over an 18 month study period, 323 residents that lived in the NH and had a cognitive performance score of 5 or 6 (a score of 5 is approximately an MMSE of 5.1) and a global deterioration score of at least 7 (inability to recognize family, incontinent, functionally dependent, unable to ambulate). 54.8% died in 18 mo; 24.7 % died in the 1st 6 mo. Median survival was 478 days. The figure has the cumulative incidence of each event, mortality rates at 6 months after the incident is at the side. In other words, during the 18month study period, 41.1% had pneumonia, 52.6% had a febrile episode, and 85.8% had an eating problem. The 6 month mortality rates after each event is listed above (46.7, 44.5, and 38.6% respectively). The mortality rates were substantially higher in the group that developed these complications compared to those who did not have a complication.
Importantly guidelines state other factors may indicate a prognosis of 6 months or less and should be taken into account when considering a patient appropriate for hospice services
