Objective To evaluate the disease economic burden associated with bacillary Shigellosis and probe its determinants in partial districts of Shanghai and provide the economical basis for formulating the scientific prevention strategy against bacillary Shigellosis.
Methods Questionnaires were used to investigate the direct medical costs and direct non-medical costs, and human capital method was adopted to evaluate the indirect economic burden of 534 cases of bacillary Shigellosis in partial districts of Shanghai from Apr 2009 to Apr 2010. The multi-linear regression model was used to explore the determinants of direct economic burden and indirect economic burden of bacillary Shigellosis.
Results The average direct burden of outpatient and inpatient bacillary Shigellosis cases were 530.79 and 3 004.57 Yuan(RMB)respectively in partial districts of Shanghai, and the average indirect burden were 243.13 and 328.02 Yuan respectively. The average total economic burden of outpatient and inpatient bacillary Shigellosis cases were 773.92 and 3 332.59 Yuan respectively. Multi-linear regression model showed that age, status of medical insurance, severity of symptoms, days from onset to diagnosis, hospital level and resdential district were determinants of direct economic burden, meanwhile, residential district and age were determinants of indirect economic burden.
Conclusion The economic burden associated with bacillary Shigellosis in Shanghai should not be ignored, particularly, the economic burden of inpatient bacillary Shigellosis cases was comparatively high. It is still necessarily to strengthen the prevention and control of bacillary Shigellosis.
