Frequency and Characteristics of Patients Prescribed Antibiotics on Admission to Hospice Care

Little is known about antibiotic prescribing on hospice admission despite known risks and limited evidence for potential benefits. To describe the frequency and characteristics of patients prescribed antibiotics on hospice admission. Cross-sectional study. Adult (age ≥18 years) decedents of a national, for-profit hospice chain across 19 U.S. states who died between January 1, 2017 and December 31, 2019. The primary outcome was having an antibiotic prescription on hospice admission. Patient characteristics of interest were demographics, hospice referral location, hospice care location, census region, primary diagnosis, and infectious diagnoses on admission. We used multivariable logistic regression to quantify associations between study variables. Among 66,006 hospice decedents, 6080 (9.2%) had an antibiotic prescription on hospice admission. Fluoroquinolones (22%) were the most frequently prescribed antibiotic class. Patients more likely to have an antibiotic prescription on hospice admission included those referred to hospice care from the hospital (adjusted odds ratio [aOR] 1.13, 95% confidence interval [CI] 1.00-1.29) compared with an assisted living facility, those receiving hospice care in a private home (aOR 3.85, 95% CI 3.50-4.24), nursing home (aOR 3.65, 95% CI 3.24-4.11), assisted living facility (aOR 4.04, 95% CI 3.51-4.64), or hospital (aOR 2.43, 95% CI 2.18-2.71) compared with inpatient hospice, and those with a primary diagnosis of liver disease (aOR 2.23, 95% CI 1.82-2.74) or human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (aOR 3.89, 95% CI 2.27-6.66) compared with those without these diagnoses. Approximately 9% of hospice patients had an antibiotic prescription on hospice admission. Patients referred to hospice from a hospital, those receiving care in a noninpatient hospice facility, and those with liver disease or HIV/AIDS were more likely to have an antibiotic prescription. These results may inform future antimicrobial stewardship interventions among patients transitioning to hospice care.
