Effects of changes in ICU bed supply on ICU utilization.
The purpose of this study was to determine the relationship between intensive care unit (ICU) bed supply and ICU admission in US hospitals. Using a difference-in-differences approach, researchers compared the risk-adjusted probability of ICU admission at hospitals that increased their ICU bed supply over time with matched hospitals that did not. Subjects were three patient groups with a low likelihood of benefiting from ICU admission: low-severity patients with acute myocardial infarction and pulmonary embolism, and high-severity patients with metastatic cancer at the end of life. Results showed that increases in ICU bed supply were associated with inconsistent changes in the probability of ICU admission that varied across patient subgroups.

Impact of a sequential intervention on albumin utilization in critical care.
The authors evaluated the effect of a sequential multifaceted intervention on decreasing albumin use in the intensive care unit. They found that a sequential intervention achieved significant reductions in albumin use and cost savings without changes in patient outcomes, supporting the combination of financial and nonfinancial strategies to align providers with evidence-based practices.

Capacity and utilization in health care: the effect of empty beds on neonatal intensive care admission.
In this paper, the author exploited short-term variation in Neonatal Intensive Care Unit (NICU) capacity that is unlikely to be correlated with unobserved demand determinants. He found that available NICU beds have little to no effect on NICU utilization for the sickest infants, but do increase utilization for those in the range of birth weights where admission decisions are likely to be more discretionary.
