Abstract

Objective: We conducted a systematic review and meta-analysis to: 1) compare time from traumatic spinal injury (TSI) to operating room (OR) in high-income countries (HICs) versus low-middle-income countries (LMICs), and 2) evaluate hospital length of stay (LOS) in HICs versus LMICs.

Methods: A systematic literature search was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines involving articles of all languages.

Inclusion criteria: published between 1991 and 2021, spine trauma population, single country/region, and recorded time from injury to OR. The primary outcome was time from injury to OR, and the secondary outcome was LOS. Means and standard deviations were estimated in a random effects model by DerSimonian and Laird methods.

Results: Of 2367 articles, 163 met the inclusion criteria for systematic review. Regarding time from injury to OR, 23 articles were eligible for meta-analysis; 16 studies were conducted in HICs and 7 in LMICs, comprising 3819 patients with TSI. A significantly shorter mean time from injury to OR was found in HICs (1.92 days, 95% confidence interval 1.44-2.41) compared with LMICs (3.27 days, 95% confidence interval 2.27-4.27) (P = 0.020). Regarding length of stay, 14 articles were eligible for meta-analysis, 10 studies were conducted in HICs and 4 in LMICs, comprising 11,003 patients. There was no difference in LOS between HICs and LMICs (25.76 days vs. 20.48 days, P = 0.140).

Conclusions: Patients with traumatic spinal injuries in HICs were more likely to undergo earlier surgery compared to patients in LMICs. No difference was found in total LOS between HICs and LMICs. While multiple factors can influence time to surgery, these findings draw attention to the global disparity in spinal trauma care.
