Abstract

Objective: To investigate whether utilizing a LDL-direct laboratory test rather than a lipid panel to determine LDL-C as part of the inpatient stroke and TIA workup is more cost-effective to the patient and hospital system. A retrospective analysis was conducted on all patients admitted to UCSD La Jolla and Hillcrest Hospital and discharged with a final diagnosis of ischemic stroke or transient ischemic attack between 7/2016 and 6/2019. A cost-analysis was extrapolated based on the current cost of each test as provided by the UCSD hospital billing department as of June 2020. Patients started on a statin, who were not on one prior to admission, were also analyzed to highlight the importance of an accurate LDL-C on management of dyslipidemia.

Results: A total of 1245 patients were included in the study with 87% representing Ischemic strokes and 13% transient ischemic attacks. Over the three-year period, a total savings of $77,545 would be achieved if LDL-direct were used in place of a lipid-panel, representing an overall cost savings of 33%. Over the same time-frame, 536 (43%) patients were started on a statin that were not previously on one.

Conclusions: Ordering a LDL-direct test should be considered over a lipid panel to evaluate LDL-C as it may prove to be the most cost effective approach to both the patient and Healthcare system.
