Reducing lead time for acute MRI

(2013) Brandsema, Gerben

Purpose: The purpose of this study is to increase the performance of the MRI modalities at the University Medical Center Groningen (UMCG) with respect to lead time reduction of acute patients with minimal impact on the elective capacity.
Methodology/Approach: 2011 data is used to analyse the patient populations and to look at radiology reporting performance. Furthermore, a two week observation is conducted to gather enough data about the MRI process. 224 examinations are timed and the MRI process is observed to see where variability enters the process.
Findings: By better estimating protocol times, inserting intravenous access lines outside the MRI room and improving the supply chain, 60 minutes per day can be unlocked in the elective capacity. This unlocked capacity can be used for emergency capacity which results in a total of 150 minutes of emergency capacity per day, because currently there is already 90 minutes of emergency capacity available per day. This is enough to examine a population of acute patients within 24 hours that are currently examined within 96 hours after the request for an MRI scan.
Originality/Value: The results of this study contribute to a more efficient use of MRI capacity within the UMCG. Within literature there is little known about optimisation of diagnostic departments compared to other central facilities such as operating rooms and outpatient departments (Elkhuizen et al., 2007). This study contributes to the knowledge of optimising diagnostic departments and more specific, the optimisation of MRI diagnostics.
