The Impact of Obesity in End of Life Care in Patients With End Stage Liver Disease: An Observational Study

Background: Both obesity and end stage liver disease (ESLD) are increasing. Obesity's impact on hospice and palliative care in patients with ESLD is unknown. Methods: We retrospectively evaluated patients admitted to an academic, Midwestern, tertiary center between January 2016 and May 2019 with a diagnosis of ESLD. Body Mass Index and MELD Na were calculated for each patient's first admission during the study period. Patients with MELD Na scores >= 21 or 18-20 with additional criteria were considered potentially eligible for hospice and palliative care referrals. Results: Of 3863 patients admitted with ESLD, 1556 (40%) were potentially eligible for hospice and palliative care referrals. Of these, 703 (45%) were obese. Comorbidity burden was higher in obese patients (15.6% of obese patients had a Charlson Comorbidity Index >= 5, while 5% of non-obese patients had a comorbidity index of >= 5 (p < 0.001). Referral rates to hospice and palliative services in obese patients were 10.1% and 16.4% respectively. Hospice and palliative referral rates among non-obese patients were similar (10.1% and 15.5%). Among patients who died within 6 months of the first hospitalization, the mean time to referral to hospice or palliative care from index admission was longer in obese patients. Conclusion: Obesity is common in patients hospitalized with ESLD who may be approaching the end of life. Referral rates to hospice and palliative care services are low and similar regardless of BMI and despite higher co-morbidity burdens in obese patients. Obesity may delay referrals to hospice and palliative care.
