Shorter Length of Stay May Be Better for Some PE Patients

Research shows a shorter length of stay in hospitals for patients with low-risk pulmonary embolism can be better for both their health and their wallet.


Discharging patients with low-risk pulmonary embolism (PE) sooner not only saves money, but it could be saving their lives, according to a study of 6,746 VHA patients with PE.

Of the patients, 1,918 were low-risk, and of those, 688 had a short length of stay (LOS) (2 days or less). While adverse events associated with PE (recurrent venous thromboembolism, major bleeding, and death) were similar, patients with short LOS had fewer hospital-acquired complications (1.5% vs 13.3%) and bacterial pneumonias (5.9% vs 11.7%). Patients in the long LOS cohort had a higher number of pharmacy visits per patient (12.2 vs 9.4) and surgeries for placement of the inferior vena cava filter.

The researchers note that PE is associated with a “substantial burden” of health care utilization and associated costs. The annual cost per patient for an initial episode of PE ranges from $13,000 to $31,000; with recurrent episodes, the cost can be $11,014-$14,722 per year. In this study, inpatient costs for short LOS were half those of the longer LOS costs ($2,164 vs $5,100). Total costs were $9,056 for short LOS vs $12,544.

But they also note that since patients with low-risk PE can be identified using the validated risk stratification tools, an opportunity exists to select patients who can be safely treated without a traditional hospital admission. The researchers cite estimates that, in fact, up to 50% of PE patients can be treated safely as outpatients. Although this is common practice in Europe, U.S. physicians have been less willing to adopt the strategy, they add.

Risk stratification, the researchers conclude, is “of utmost importance”: Reducing the LOS among low-risk PE patients may substantially reduce the disease’s clinical and economic burden.
