The Association of Symptom Severity and Functional Status Among Patients Who Received Palliative Consults (Sch476)

ABSTRACT

1. Describe the association of functional status and symptom severity for 10 common symptoms among patients who receive palliative care consultation. 2. Consider the interaction of functional status and different symptoms when managing symptoms of patients who receive palliative care consultations. The interaction of functional status and individual symptoms has never been comprehensively investigated in palliative care (PC) populations. Therefore, we studied the relationship between the Karnofsky Performance Status (KPS) and the prevalence and severity of 10 common symptoms among hospitalized patients at the time of PC consult. Weretrospectively analyzed data from a registry of PC consults across five hospitals within the Mount Sinai Health System between January 1, 2020, and December 31, 2021. Demographics and ICD-10 codes were extracted from electronic medical and billing records. During consult, PC clinicians assessed functional status using the KPS at the time of consult (0%-100%) and symptom burden using the 10-item Edmonton Symptom Assessment Scale (ESAS), which rates each symptom as none, mild, moderate, or severe. The association of KPS and ESAS symptom severity was assessed using ordinal logistic regression models, adjusting for age, gender, Elixhauser comorbidity index, and the underlying serious illness (cancer, sepsis, dementia, COVID-19). The study population included 6,065 patients (mean age 70±16 years, 50.9% male). The most frequent underlying serious illnesses were sepsis (36.6%), cancer (32.9%), and dementia (22.8%). In regression analysis, KPS was significantly associated with symptom severity for all ESAS symptoms (p<0.001). However, symptoms separated into two different groups. Drowsiness (β=-0.85), inactivity (β=-0.71), dyspnea (β=-0.21), anorexia (β=-0.19), and agitation (β=-0.06) were negatively associated with KPS (ie, lower functional status was associated with more severe symptoms), whereas nausea (β=0.2), anxiety (β=0.15), physical discomfort (β=0.13), depression (β=0.13), and constipation (β=0.06) were positively associated with KPS (ie, lower functional status was associated with milder symptoms). These associations remained statistically significant after adjusting for baseline characteristics. While some symptoms were more severe, other symptoms were less severe among patients with poor functional status. This observation can inform symptom management and warrants further investigation.
