Objective

We wanted to study the impact of doing ECHO and MRI on length of stay (LOS) and hospital charges in ischemic stroke patients from a Nationally representative database

Background ECHO and brain MRI are often done as a part of work up of IS patients. Impact of doing ECHO and MRI on LOS and hospital charges in ischemic stroke patients has not been well described

Design/Methods IS patients from NIS database for years 2006-2014 were identified using the ICD 9 codes. We compared LOS and hospital charges in IS patients getting ECHO only, MRI only, both ECHO and MRI, with the control group with neither ECHO nor MRI. Prolonged length of stay (PLOS) is defined as greater than 4 days of hospital stay. In multivariate analysis PLOS was adjusted with age, gender, significant medical co-morbidities, in-hospital complications, and APRDRG_Severity.

Results Of 3,968,427 patients with IS, 10.1% patients got only ECHO, 4.6% got only MRI, 2.3% got both ECHO and MRI and 83.0% did not get either ECHO or MRI. In univariate analysis, the mean length of stay (p= <.0001) and mean hospital charges (p= <.0001) were significantly higher in IS patients getting ECHO only, MRI only, both ECHO and MRI, when compared to patients who did not get either ECHO or MRI. In multivariate analysis the PLOS was higher in ECHO only (OR: 1.19, CI: 1.17-1.20, p=<.0001), MRI only (OR: 1.14, CI: 1.10-1.18, p=<.0001), and both ECHO and MRI groups (OR: 1.79, CI: 1.59-2.00, p=<.0001), when compared to the control group.

Conclusions LOS and hospital charges were significantly higher in IS patients getting either ECHO or MRI or both. An important question is whether those tests impact treatment or prevention strategies to justify their performance? Further studies are needed to establish the role of echo and MRI on therapy as to justify their cost.
