Abstract
Oblique lateral lumbar interbody fusion (OLLIF) is a minimally invasive lumbar surgery. Differences in resource consumption between open spinal surgeries, transformational lumbar interbody fusions (TLIF) and OLLIF, are not documented. We monetize quantifiable differences in resource utilization between the two procedures. A retrospective review of 124 surgeries was performed (OLLIF=69, TLIF=55). Standard conversion factors were used and values reported based on the levels (1-4) addressed at surgery. One level surgery time (OLLIF 62.9 vs. TLIF 134.9 minutes) and surgical expense (OLLIF $5,253 vs. TLIF $11,264) were reduced in the OLLIF population. Inpatient costs (OLLIF $5,712 vs. TLIF $9,271) and length of stay (LOS) were also reduced (OLLIF 2.6 vs. TLIF 4.2 days). Per case, reduced resource consumption suggests lower total hospital costs. Reduced surgical time and LOS can result in greater patient throughput per operating room and patient bed for OLLIF patients in hospitals that have resourced constrained environments.
Highlights
Low back pain affects up to 80% of all people at some point during their lifetime and is one of the most expensive and prevalent health conditions in the Western world [1,2]
We present perioperative outcome data from 69 Oblique lateral lumbar interbody fusion (OLLIF) procedures, compare them to 55 open transformational lumbar interbody fusion (TLIF) on 125 levels done by the same surgeon, and monetize quantifiable differences in the resource utilization between the two procedures
There were no significant differences between the groups in either BMI or age
Summary
Low back pain affects up to 80% of all people at some point during their lifetime and is one of the most expensive and prevalent health conditions in the Western world [1,2]. The standard treatment for lower back pain, interbody fusion, in an invasive procedure that requires stripping the muscles and soft tissue. This leads to increased blood loss and a long recovery time. This procedure is normally performed for patients that require a spinal fusion but do not want the recovery time required in a traditional spinal fusion surgery. We present perioperative outcome data from 69 OLLIF procedures, compare them to 55 open TLIFs on 125 levels done by the same surgeon, and monetize quantifiable differences in the resource utilization between the two procedures
