Abstracts

Background: We introduced a (Nursery) School Absenteeism Surveillance System ((N)SASSy) in 2009,which recorded information related to students who were absent from nursery schools and schools because of disease infection. As of the end of March, 2010, was activated it at the all schools in those prefectures.It expanded to include another 8 prefectures in the following two years.

Objective: We evaluated this system using a nationwide database (National Database of Electronic Medical Claims (NDBEMC)) that includes 96.2% of all medical claims from medical institutions in Japan.

Methods: To evaluate association among (N)SASSy and incidence, we regressed the number of disease patients on whether (N)SASSy was used in those prefectures or not and other control variables. We examined common pediatric infectious diseases: influenza; varicella; respiratory syncytial virus infection (RS); hand, foot and mouth disease (HFMD); mycoplasma pneumonia (MP); aseptic meningitis (AM);erythema infectiosum (EI); exanthem subitum (ES); and herpangina.

Results: Significant effects of (N)SASSy were found on the prevalence of influenza, varicella, HFMD, MP, AM, and herpangina. When (N)SASSy started, the number of patients with these diseases declined by 53, 20, 192, 89, 73, and 38% in comparison with their respective averages.

Conclusion: We proved that negative association among (N)SASSy and the incidence of some infectious diseases. Moreover, association seems to be strong.
