Factors Associated With Inpatient Hospice Utilization Among Hospitalized Decedents With Comfort Measures Only Status

Patients with serious illness may elect to transition their care to comfort measures only (CMO) while in the hospital. Although studies have shown that routine hospice care is underutilized, the rate of general inpatient hospice (GIP) use among CMO patients during their terminal admission remains unclear. We sought to (1) examine the rate of GIP utilization and (2) identify factors associated with its use among hospitalized CMO decedents. CMO decedents in two academic, tertiary care hospitals in the United States who died between October 1, 2020 and October 31, 2021, were subgrouped based on their primary medical service (GIP vs. non-GIP) at the time of inpatient death. Data abstracted from the electronic health record included demographics, primary diagnosis codes, Rothman Index (RI), time of CMO order, ordering clinician type, time of death, and length of stay (LOS). Multivariable logistic regression analysis was performed, adjusting for relevant covariates. Of 1475 CMO decedents, only 321 (n = 22%) patients received GIP. On multivariable analysis, CMO patients who died in an ICU were five times less likely (odds ratio [OR] = 0.18, confidence interval [95% CI] 0.11-0.29) to receive GIP. Every 10-point increase in RI raised the likelihood of receiving GIP by 59% (OR = 1.59, 95% CI 1.39-1.80). Most CMO decedents died in the hospital without GIP. Compared with GIP decedents, non-GIP decedents were less acutely ill. There was no difference in total LOS between the two groups. CMO decedents were much less likely to receive GIP in an ICU. The RI may help clinicians identify CMO patients who would benefit from GIP earlier in their terminal admission.
