N2 - Background: Due to rapidly rising health care costs, leveraging outpatient surgery to reduce hospital inpatient burden is being explored. This study provides a systematic review of the literature on outpatient anterior lumbar interbody fusion (ALIF) with pooled analysis to determine its safety and feasibility. Methods: Embase (Elsevier), MEDLINE (National Library of Medicine), CINAHL (EBSCO), and the Cochrane Library (Wiley) were searched on 8 April 2024 for articles mentioning the following search concepts: (1) ambulatory; (2) outpatient; and (3) ALIF surgery. Included studies had (1) patients undergoing outpatient ALIF; (2) an inpatient control group; (3) a sample size of ≥5 in each cohort; and (4) a population aged ≥18 years. Outcome data were extracted from studies meeting inclusion criteria, and Newcastle-Ottawa scores were assigned to included studies lacking a prospective, randomized design. Fixed and random effects models were used to establish ORs and mean difference with 95% CIs for each outcome. Results: Pooled analysis included results from 4 studies. A total of 2070 patients underwent outpatient ALIF and 12,554 underwent inpatient ALIF. The results showed that compared with inpatient ALIF, outpatient ALIF resulted in a statistically significant decrease in postoperative adverse events (OR −0.89, 95% CI [−1.69, –0.09], I2 = 54.88%, P = 0.03), comparable readmission rates (OR 0.02, 95% CI [−0.16, 0.20], I2 = 0%, P = 0.816), and nearly statistically significant decrease in reoperation rates (OR −0.41, 95% CI [−0.83, –0.00], I2 = 0%, P = 0.05). Discussion: These meta-analyses suggest that outpatient ALIF is associated with a statistically significant decrease in postoperative adverse events without a significant difference in hospital readmission or reoperation rates. These results suggest that in carefully selected patients, outpatient ALIF is safe and feasible. This study is limited by pooled analysis of retrospective data.
