Better prevention and treatment of pneumonia and other common ambulatory conditions in nursing homes could reduce avoidable hospitalizations for residents while saving Medicare and other public programs money, according to a Commonwealth Fund-supported study in the journal Health Affairs.
Using hospital and nursing home data from New York State, David C. Grabowski, Ph.D., of Harvard Medical School, and colleagues found that inflation-adjusted spending on nursing home hospitalizations rose 29 percent from 1999 through 2004, with aggregate spending totaling $972 million by 2004. Nearly one-quarter of these costs were for ambulatory care-sensitive conditions, including pneumonia, kidney or urinary tract infections, and congestive heart failure.
"The high concentration of spending in relatively few conditions suggests that targeted prevention and treatment interventions in nursing homes could be particularly fruitful," the authors said in their article, "The Costs and Potential Savings Associated with Nursing Home Hospitalizations" (Health Affairs, Nov./Dec. 2007).
Until now, little has been known about the amount of savings associated with nursing home hospitalizations. Using New York State data, the researchers found annual total spending on nursing home hospitalizations increased from about $608 million in 1999 to $971.7 million in 2004. In examining ambulatory care-sensitive hospitalizations, the team found annual total spending rose from $169 million in 1999 to $223.8 million in 2004, or a 7.1 percent increase in spending when adjusted for inflation.
The researchers also looked at 14 ambulatory care sensitive conditions to identify potentially avoidable hospitalizations. Of the 122,027 nursing home hospitalizations over the period, nearly one-third (31.3%) were deemed potentially avoidable. Such hospitalizations accounted for $1.24 billion in spending (in 2004 dollars). Pneumonia was the most common diagnosis, accounting for 33 percent of ambulatory-care sensitive hospitalizations, followed by kidney/urinary tract infections, congestive heart failure, and dehydration. The average spending per ambulatory-care sensitive hospitalizations was $10,140.
The researchers offer several explanations for the higher rates of hospitalization: the increasingly sicker and more disabled population served by nursing homes; the growing nursing shortage; a recent increase in lawsuits, which has led facilities to hospitalize patients to avoid litigation; and nursing home cost growth that outpaces payment rates, leaving homes without the resources to care for residents.
The authors contend that policies to decrease potentially avoidable nursing home hospitals could result in substantial savings, including:
