Assessment of Guillain-Barre syndrome mortality and morbidity in the United States: Implications for acute flaccid paralysis surveillance

To estimate age-specific incidences and assess the national morbidity and mortality burden for Guillain-Barre syndrome (GBS) in the United States, a national hospital discharge database compiled by the Commission on Professional and Hospital Activities (CPHA) and national death certificate data reported to the National Vital Statistics System were reviewed. During 1985-1991, 10,453 patients with GBS were discharged from CPHA-participating hospitals (estimated annual incidence, 3.0/100,000 population). The age-specific incidence of GBS increased with age from 1.5/100,000 in persons <15 years old to 8.6/100,000 in persons 70-79 years old. The total estimated number of GBS-related deaths from 1985 through 1990 was 3770 (95% confidence interval, 3506-4034), for an average of 628 GBS deaths per year. These rates suggest that the proposed national surveillance system for acute flaccid paralysis should capture at a minimum the 796 GBS cases in persons <15 years old. GBS remains a significant health burden among older adults in the United States, with a marked increase in risk after age 40.
