Some ICU admissions may be preventable, saving money and improving care

While there's no universal standard for what constitutes a preventable ICU admission, those with chronic medical conditions may be good candidates.

Many admissions to the intensive care unit may be preventable, potentially decreasing healthcare costs and improving care, according to new research published online in the Annals of the American Thoracic Society.

In "Potentially Preventable Intensive Care Unit Admissions in the United States, 2006 - 2015," the authors analyzed more than 16 million ICU admissions and estimated that between one in six and one in seven such admissions might have been avoided.

The wellspring of this conclusion comes from three large data sources from 2006-15: Medicare Fee-for-Service, a Medicare Advantage plan and a large private national insurer. Altogether, the data sources represented nearly two-thirds of U.S. adults age 65 and older and about 13 percent of the U.S. population. During this time, there were nearly 100 million hospital admissions, of which 16.7 percent included an ICU admission.

WHAT'S THE IMPACT

The authors acknowledge in the article that there is no "gold standard" definition of a preventable ICU admission. For their analysis, they identified two patient groups whose care could potentially be handled better outside the ICU: those with an "ambulatory care sensitive condition" and those with a "life-limiting malignancy" who are nearing the end of their life.

Those in the first group have a chronic or medical condition such as high blood pressure, urinary tract infection or uncontrolled diabetes that, with timely outpatient care, can prevent the patient from being hospitalized.

Those in the second group are patients with cancer who are likely to die within a year, and for whom palliative care may be appropriate. Although the authors only looked at life-limiting malignancy, they noted that ICU admissions may be preventable for other serious illnesses, including chronic lung disease, heart failure and neurodegenerative disorders.

They also found that, over the 10-year time period, ICU hospitalizations for ambulatory care sensitive conditions have been slowly decreasing while the proportion of those in the ICU with a life-limiting malignancy has been increasing.

There were wide regional differences in ICU admissions and an almost eight-fold difference among states in the rates of ICU admissions. The rate of ICU admissions in different geographic areas among these two patient groups appears to be partially explained by the number of ICU beds available.

The authors said these findings may suggest a strategy for the expected increase in ICU services as the U.S. population ages.

"A substantial portion of ICU admissions in the U.S. may be prevented," they wrote. "Investing in outpatient, preventive and palliative services should therefore be viewed as an important complementary, if not alternative, strategy to increasing the critical care workforce in seeking to provide the best care for the nation's sickest patients."

THE LARGER TREND

Patient care also improves when physicians and nurses are able to ameliorate their levels of stress, and the ICU can be a stress-inducing environment.

A Penn Medicine pilot study published in June found that shortening the length of rotations in an ICU from the traditional 14-consecutive day schedule to only seven days helps mitigate burnout among critical care physicians.

Work-related burnout, characterized by emotional or physical exhaustion, as well as feeling cynical or detached, is common among physicians -- particularly intensivists, or critical care physicians, who care for critically ill patients. Nearly half of the 10,000 critical care physicians practicing in the U.S. reported symptoms of severe burnout, which can lead to compassion fatigue, decreased quality of care and job turnover.
