Background. The physical signs of impending death have not been well characterized in cancer patients. A better understanding of these signs may improve the ability of clinicians to diagnose impending death. We examined the frequency and onset of 10 bedside physical signs and their diagnostic performance for impending death. Methods. We systematically documented 10 physical signs every 12 hours from admission to death or discharge in 357 consecutive patients with advanced cancer admitted to two acute palliative care units. We examined the frequency and median onset of each sign from death backward and calculated their likelihood ratios (LRs) associated with death within 3 days. Results. In total, 203 of 357 patients (52 of 151 in the U.S., 151 of 206 in Brazil) died. Decreased level of consciousness, Palliative Performance Scale #20%, and dysphagia of liquids appeared at high frequency and .3 days before death and had

Background We recently reported 5 highly specific physical signs associated with death within 3 days among cancer patients that may aid the diagnosis of impending death. In this study, we examined the frequency and onset of an additional 52 bedside physical signs and their diagnostic performance for impending death. Methods We enrolled 357 consecutive patients with advanced cancer admitted to acute palliative care units at two tertiary care cancer centers. We systematically documented 52 physical signs every 12 hours from admission to death or discharge. We examined the frequency and median time of onset of each sign from death backwards, and calculated their likelihood ratios (LRs) associated with death in 3 days. Results 203/357 (57%) patients died at the end of the admission. We identified 8 physical signs that were highly diagnostic of impending death. These signs occurred in 5-78% of patients in the last 3 days of life, had a late onset, and had a high specificity (>95%) and high positive LR for death within 3 days, including non-reactive pupils (positive LR 16.7, 95% confidence interval 14.9-18.6), decreased response to verbal stimuli (8.3, 7.7-9), decreased response to visual stimuli (6.7, 6.3-7.1), inability to close eyelids (13.6, 11.7-15.5), drooping of nasolabial fold (8.3, 7.7-8.9), hyperextension of neck (7.3, 6.7-8), grunting of vocal cords (11.8, 10.3-13.4), and upper gastrointestinal bleed (10.3, 9.5-11.1). Conclusion We identified 8 highly specific physical signs associated with death within 3 days in cancer patients. These signs may inform the diagnosis of impending death.

Context The symptom burden in the last week of life of patients with advanced cancer has not been well characterized. Objectives To examine the frequency, intensity, and predictors for symptoms in the last seven days of life among patients who were able to communicate and died in an acute palliative care unit (APCU). Methods We systematically documented the Edmonton Symptom Assessment System (ESAS) daily and 15 symptoms twice daily on consecutive advanced cancer patients admitted to APCUs at M.D. Anderson Cancer Center (USA) and Barretos Cancer Hospital (Brazil) from admission to death or discharge in 2010/2011. We examined the frequency and intensity of the symptoms from death backwards. Results A total of 203 of 357 patients died. The proportion of patients able to communicate decreased from 80% to 39% over the last seven days of life. ESAS anorexia (P=0.001 in longitudinal analyses), drowsiness (P<0.0001), fatigue (P<0.0001), poor well-being (P=0.01) and dyspnea (P<0.0001) increased in intensity closer to death. In contrast, ESAS depression (P=0.008) decreased over time. Dysphagia to solids (P=0.01) and liquids (P=0.005), and urinary incontinence (P=0.0002) also were present in an increasing proportion of patients in the last few days of life. In multivariate analyses, female sex, non-Hispanic race and lung cancer were significantly associated with higher ESAS symptom expression (odds ratio>1). Conclusion Despite intensive management in APCUs, some cancer patients continue to experience high symptom burden as they approached death.

Our results suggest that in patients with OSAS, myofunctional therapy may be considered as an adjuvant treatment and an intervention strategy to support adherence to CPAP.

Context Few studies have examined variation in vital signs in the last days of life. Objectives We determined the variation of vital signs in the final two weeks of life in patients with advanced cancer and examined their association with impending death in three days. Methods In this prospective, longitudinal, observational study, we enrolled consecutive patients admitted to two acute palliative care units and documented their vital signs (heart rate, blood pressure, respiratory rate, oxygen saturation, and temperature) twice a day serially from admission to death or discharge. Results Of 357 patients, 203 (55%) died in hospital. Systolic blood pressure (P < 0.001), diastolic blood pressure (P < 0.001), and oxygen saturation (P < 0.001) decreased significantly in the final three days of life, and temperature increased slightly (P < 0.04). Heart rate (P = 0.22) and respiratory rate (P = 0.24) remained similar in the last three days. Impending death in three days was significantly associated with increased heart rate (odds ratio [OR] = 2; P = 0.01), decreased systolic blood pressure (OR = 2.5; P = 0.004), decreased diastolic blood pressure (OR = 2.3; P = 0.002), and decreased oxygen saturation (OR = 3.7; P = 0.003) from baseline readings on admission. These changes had high specificity (≥80%), low sensitivity (≤35%), and modest positive likelihood ratios (≤5) for impending death within three days. A large proportion of patients had normal vital signs in the last days of life. Conclusion Blood pressure and oxygen saturation decreased in the last days of life. Clinicians and families cannot rely on vital sign changes alone to rule in or rule out impending death. Our findings do not support routine vital signs monitoring of patients who are imminently dying.
