When a patient is admitted for seizure-like activity, in addition to obtaining a thorough history and physical exam, the evaluation may include a neurology consultation, EEG, and brain MRI. The cost of an inpatient MRI is significant and only 2% of MRIs yield clinically significant findings. At our institution, there was a 20% increase in patients undergoing inpatient MRI from 2018 to 2020. Our aim: Decrease the percentage of patient encounters receiving inpatient brain MRIs for seizure evaluation from 50% to 40% in 6 months by safely shifting MRIs to the outpatient setting.
Initially, provider variability in ordering practices of MRIs was analyzed. Stakeholders were gathered and a local guideline was developed to standardize MRI utilization. A process map was created and highlighted barriers to obtaining an outpatient MRI. A new standard process was developed that streamlined and automated processes, and reduced delays and reliance on patients’ families.
Since implementation of the new clinical guideline, the percentage of inpatient MRIs ordered for patient encounters presenting with seizures and seizure-like episodes decreased from a mean of 50% to 26%. Significant reductions occurred for patients with complex febrile seizures, provoked but afebrile seizures, and unprovoked seizures. The MRI guideline recommendations were followed in 93% of encounters in the final 12 months. None of the patients who underwent outpatient MRI required readmission for acute findings.
In this project, the percentage of inpatient MRIs was safely decreased with the implementation of a clinical guideline and standardized process.
