Symptom burden and hospital length of stay among patients with curable cancer.

Abstract

6579 Background: Prolonged hospital admissions are often inconsistent with patients’ preferences and incur significant costs. While patients’ symptoms may result in hospitalizations, the relationship between patients’ symptom burden and their hospital length-of-stay (LOS) has not been fully explored in patients with curable cancers. Methods: We prospectively enrolled patients with curable cancer and unplanned hospital admissions between 8/2015 and 12/2016. Within the first 5 days of admission, we assessed patients’ physical (Edmonton Symptom Assessment System [ESAS]; scored 0-10 with higher scores indicating greater symptom burden) and psychological symptoms (Patient Health Questionnaire 4 [PHQ-4]; scored categorically and continuous with higher scores indicating greater distress). We created summated ESAS total and physical symptom variables. To assess the relationship between patients’ symptom burden and their hospital LOS, we used separate linear regression models adjusted for age, sex, marital status, education level, time since cancer diagnosis, and cancer type. Results: We enrolled 452 of 497 (91%) approached patients (mean age = 61.9 years; 188 [42%] female). Over half had hematologic cancers (n = 249, 55%). Mean hospital LOS was 8.3 days. Over one-tenth of patients screened positive for PHQ-4 depression (n = 74, 16%) and anxiety (n = 60, 13%) symptoms. Mean ESAS symptom scores were highest for fatigue (6.6), drowsiness (5.4), pain (4.9), and lack of appetite (4.8). In multivariable regression analysis, patients’ physical and psychological symptoms were associated with longer hospital LOS (table). Conclusions: Patients with curable cancer and unplanned hospital admissions experience a substantial symptom burden, which predicts for prolonged hospitalizations. Importantly, patients’ symptoms are modifiable risk factors that, if properly addressed, can improve care delivery and may have the potential to help decrease prolonged hospitalizations.
