Objective
To determine the impact of MRSA/VRE designations, or flags, on selected hospital operational outcomes.
Design
Retrospective cohort study of inpatients admitted to the Massachusetts General Hospital during 2010–2011.
Methods
Operational outcomes were time to bed arrival, acuity-unrelated within-hospital transfers, and length of stay. Demographic and clinical characteristics – including age, gender, severity of illness on admission, admit day of week, residence prior to admission, hospitalization within the prior 30 days, clinical service, and discharge destination – were used as covariates.
Results
A total of 81,288 admissions were included. After adjusting for covariates, patients with a MRSA/VRE flag at the time of admission experienced a mean delay in time to bed arrival of 1.03 (9.63 [95% CI 9.39–9.88] hours vs. 8.60 [95% CI 8.47–8.73] hours); had 1.19 times the odds [95% CI, 1.13–1.26] of experiencing an acuity-unrelated within-hospital transfer, and experienced a mean length of stay 1.76 days longer (7.03 [95% CI 6.82–7.24] days vs. 5.27 [95% CI 5.15–5.38] days) compared to patients with no MRSA/VRE flag.
Conclusions
MRSA/VRE designation was associated with delays in time to bed arrival, increased likelihood of acuity-unrelated within-hospital transfers, and extended length of stay. Efforts to identify patients who have cleared MRSA/VRE colonization are critically important to mitigate inefficient use of resources and improve inpatient flow.
