Global Burden of Complex Regional Pain Syndrome in At-Risk Populations: Estimates of Prevalence From 35 Countries Between 1993 and 2023

Anesth AnalgPublished Systematic review and meta-analysis

Authors' conclusion

This study provides a benchmark of the global prevalence of CRPS, which anesthesiologists and pain specialists can use to prioritize early diagnosis and identify those at the highest risk for CRPS.

Study context

Population
Individuals at higher risk of complex regional pain syndrome (CRPS) after an inciting event (eg, fracture, surgery), particularly posttraumatic and postsurgical patients, worldwide (35 countries)
Outcome
Prevalence of CRPS after an inciting event
Follow-up
12 months and 24 months
Methodological detailsrandom-effects model, double-arcsine transformation, subgroup analysis and meta-regression
  • Random-effects model
  • Double-arcsine transformation
  • Subgroup analysis and meta-regression

Pooled result

As reported in the abstract

Pooled global prevalence of CRPS

12-month prevalence

3.04%

95% CI 2.64–3.48

24-month prevalence

6.46%

95% CI 5.46–7.53

Further pooled results

12-month prevalence by subgroup (subgroup)

Higher in countries with high human development index (HDI) vs medium or very high HDI
Higher with traumatic inciting injury only vs surgical only or traumatic/surgical injury
Higher in prospective vs retrospective studies

Publication year (meta-regression) · 12 months

Publication year a significant moderator; more recent articles reported lower 12-month prevalence
