Tetanus immunoglobulin (TIG) and tetanus vaccination are in general use for tetanus prophylaxis in patients with trauma based on their personal history of tetanus vaccinations. However, the conventional injection of only TIG has been used for tetanus prophylaxis due to difficulties in verifying the known vaccination histories of Korean patients. We evaluated the effect of introducing an immunization information system (IIS) on tetanus prophylaxis. TIG-injected trauma patients (≥20 years old) who were registered at a single hospital from January 1, 2013 to December 31, 2015 were enrolled in this study. IIS was introduced to all doctors in that hospital starting on January 1, 2015. IIS information and medical records were used to assess histories of tetanus vaccination and TIG administration. Comparisons were made between the number of tetanus and TIG shots (inadequate TIG administrations) given before and after the introduction of the IIS. The number of TIG-injected patients varied during the study period (362 in 2013, 387 in 2014, and 235 in 2015). The proportion of tetanus-vaccinated patients relative to TIG-injected patients increased from 2.21% in 2013 to 4.13% in 2014 and 44.26% in 2015 (P <0.001). The proportions of cases that were recorded as having received inadequate TIG administration decreased from 3.59% (13 of 362) in 2013 for patients with ≥3 tetanus vaccinations to 4.39% (17 of 387) in 2014 and 1.28% (3 of 235) in 2015 for the same group P = 0.043). The introduction of IIS could increase the number of patients with trauma who have proper tetanus vaccinations and decrease the number who undergo inadequate TIG administrations. The introduction of IIS can improve clinical practice in terms of enhancing proper tetanus prophylaxis for appropriate patients.
