Patients Older Than 75 Years Undergoing Polysegmental Lumbar Fusion Surgery Can also Benefit from Enhanced Recovery After Surgery Program.

PURPOSE

To compare pain scores (visual analog scale) on postoperative days 1-3 and length of stay after implementing enhanced recovery after surgery (ERAS) in elderly patients undergoing multi-segments lumbar fusion surgery.

METHODS

We performed a retrospective analysis of prospectively collected data, patients older than 75 years were enrolled in the study. We selected two periods, before (Pre-ERAS, n =54 patients) and after (ERAS, n =46 patients) implementation of ERAS. Data were collected on patient demographics, operative and perioperative details, 30-day readmission. The primary outcome was the length of stay (LOS), and the secondary outcomes were postoperative mean pain scores on postoperative days (POD) 1-3 and 30-day readmission rates.

RESULTS

A total of 100 patients (46 in ERAS and 54 in pre-ERAS) were enrolled in this study. There were no significant differences in age, sex, body mass index (BMI), smoking and comorbidities between the groups. However, there was a significant difference in pain on postoperative day (POD) 1 (5.31 ± 1.98 vs 4.37 ± 0.85, p = 0.002), while there was no difference in postoperative complications. The mean LOS was significantly shorter in the ERAS than in the pre-ERAS group, it reduced from 12.29 ± 3.93 to 9.45 ± 2.72 days (p < 0.001).

CONCLUSION

To our knowledge, this is the first ERAS protocol used in patients (older than 75 years) undergoing polysegmental lumbar fusion surgery. Pain scores on POD 1 and LOS were significantly lower without increased adverse events after implementation of ERAS. This finding suggests that elderly people (>75 years of age) undergoing polysegmental lumbar fusion surgery could also benefit from ERAS.
