Segmented regression analysis of emergency departments patient visits from Septicemia in Taiwan.

Background: The protocol for early goal-directed therapy (EGDT) is effective for improving both the costs and outcomes of septicemia treatment, including a significant reduction in case fatality. However, this complicated protocol may have a downside. Furthermore, the Joint Taiwan Critical Care Medicine Committee has launched a nationwide educational program after the publication of the Surviving Sepsis Campaign (SSC) to improve the overall survival rate from septicemia in the emergency care system of Taiwan.

Objectives: To assess the impact of the EGDT protocol and SSC education programs on island-wide septicemia-related emergency department (ED) visits.

Methods: Segmented regression techniques were utilized to assess the differences in annual rates and changes in septicemia-related ED visits between 1998 and 2012. We considered annual incidence of two medical comorbidities as potential confounders: metastatic malignant neoplasms and malignant neoplasms of the lymphatic and hematopoietic tissues.

Results: The EGDT protocol was associated with decreased septicemia-related ED visits in 2002 (level change; < 0.001), while the SSC education program led to a slight increase in septicemia-related ED visits in 2007 (slope change; < 0.001). For the EGDT protocol, the number of patient visits decreased by 32.9% after the protocol was implemented in 2002 compared with the expected number without the intervention. For the SSC education program, the number of patient visits increased by 20.2% (compared with the predicted number) in 2007 after the education program was implemented.

Conclusions: The EGDT protocol and SSC education program were associated with significant immediate changes and lagged intervention effects on island-wide septicemia-related ED visits.
