CMS Updates Medicare Hospice Statistics

The Centers for Medicare & Medicaid Services (CMS) is providing updated hospice statistics from 1998 to 2008. The statistics include the 20 most frequent diagnoses, the number of patients, average length of stay, and trends over time in length of stay, by diagnosis.

From the data trends report:
Hospice Terminal Diagnoses

The table also shows that the frequency of some hospice terminal diagnoses has changed over time, with relatively fewer cancer patients and relatively more non-cancer patients as a percentage of total hospice patients. The percentage of all Medicare hospice patients with a terminal diagnosis of cancer dropped from 52.8% in 1998 to 31.1% in 2008 [data not shown]. Lung cancer has been recognized as the most common diagnosis among Medicare hospice patients every year since 1998. However, in 2006 non-Alzheimer’s dementia became the most common diagnosis among Medicare hospice patients. The percentage of Medicare hospice patients with lung cancer dropped from 16% in 1998 to 9% in 2008. In addition, we are seeing a notable increase in the number of neurologically-based diagnoses. We are also seeing a marked increase in non-specific diagnoses such as “Debility, Not Otherwise Specified”, and “Adult Failure to Thrive”.

Average Length of Stay

Along with the shift in the mix of hospice patients, there exists a significant increase in the average length of stay (LOS) for hospice patients. In 1998, the average LOS for hospice patients was 48 days, but by 2006 it had risen to 73 days (a 52% increase). Since 2006, the average LOS has begun to decline slightly, dropping to 71 days in 2008, which is a 48% increase from 1998. Charts 1 and 2 show that the average LOS varies by diagnosis. For the top twenty diagnoses in 2008, the average LOS ranged from 28 days for chronic kidney disease to 105 days for Alzheimer’s disease and other degenerative conditions. While the average LOS from 1998–2008 for hospice patients with diagnoses such as chronic kidney disease or cancers has remained relatively stable, the average LOS rose significantly for most other diagnoses, thought it has recently begun to decline slightly. Charts 1 and 2 graphically demonstrate the difference in the changes in lengths of stay for cancers versus other diagnoses in the top 20 list.
