The Association of Increasing Hospice Use With Decreasing Hospital Mortality: An Analysis of the National Inpatient Sample.

EXECUTIVE
SUMMARY: Usage of hospice services for patients facing life-limiting illness has steadily increased. In these services, hospitals discharge patients to various hospice settings, including the inpatient model, where a patient may remain in the discharging hospital to receive hospice services. In this discharge practice, the patient is considered a hospital survivor and subsequent hospice death. The purpose of the study was to determine if the decline of in-hospital mortality for six common high-volume admission diagnoses could be attributed in part to an increase in discharges to a hospice setting for end-of-life care. In this retrospective study using the National Inpatient Sample database from 2007 to 2011, we identified patients ≥18 years for six acute and chronic diagnoses: heart failure, chronic obstructive pulmonary disease, acute myocardial infarction, acute myocardial infarction with cardiogenic shock, septic shock, and lung neoplasm (cancer). We categorized patients according to their hospital discharge disposition as hospice or in-hospital mortality. A total of 10,458,728 patients met our criteria, of which 2.72% were discharged to hospice and 6.38% died. Compared to patients who died in the hospital, hospice patients were older, had a shorter length of stay, and experienced more comorbidities. Hospice use was more common in Medicare patients, in nonteaching hospitals, and in the South. White individuals were more likely to be discharged to hospice compared to nonwhites. Among the six selected diagnoses over the 5-year period, hospice use rose as observed mortality decreased. Our findings suggest that variability among hospitals in hospice use will affect benchmarked hospital mortality comparisons and could inappropriately reward or penalize hospitals in their public reporting.
