Study characteristics, ERAS elements, and outcomes were analyzed and meta-analyses were performed for length of stay (LOS) and cost outcomes. The number of spine ERAS studies from low-middle-income countries (LMICs) increased since 2017, when the first spine ERAS implementation study was published. LMICs were more likely than high-income countries (HICs) to conduct studies on patients aged ≥18 years (odds ratio [OR], 6.00; 95% CI, 1.58-42.80), with sample sizes 51 to 100 (OR, 4.50; 95% CI, 1.21-22.90), and randomized controlled trials (OR, 7.25; 95% CI, 1.77-53.50).
