Cost Effective Virtual Intensive Care Unit Expanding Capabilities in Critical Access Hospitals

Tele-consults provide access to specialized care for a specific question and single point in time. eICU models utilize remote monitoring and ordering but have significant financial burden. We developed a virtual intensive care unit (VICU) for daily input of an intensivist working with local physicians. The purpose was to expand the acute care ability of the critical access hospital (CAH). The study evaluates the impact on the CAH and system.

The CAH developed an ICU team, led by a hospitalist, who staffed the intensive care unit (ICU). The CAH ICU team rounds daily via a secure video link to provide care in consultation with intensivists based at a university, tertiary care center (TC). A retrospective analysis was conducted 6 months before and after implementation (4/2018-3/2019). Fisher's exact test was used to compare pre- and post-intervention with significance at P < .04.

After VICU implementation, there were 265 initial daily and 35 follow-up consults. Monthly transfers to a higher level of care decreased from 63 to 57 (P = .03). Transfers to TC increased from 49.6 to 62.0% (P = .001). Critical access hospital average monthly census and average monthly inpatient days increased (69 to 130 (P < .0001) and 158 to 319 (P < .0001), respectively). Critical access hospital physicians report increased comfort to admit ICU and non-ICU patients due to the program. The total startup cost was $5180. CAH hired 11 providers. There were no unanticipated deaths.

VICU implementation resulted in new CAH jobs. The CAH experienced increased inpatient census and revenues (ICU and non-ICU) while decreasing patients transferred out of the system.
