The sufficient multidisciplinary specialists under a government-led health care system associated with the downward mortality trend of Fournier's gangrene in Taiwan

Objectives: To explore the trends in Fournier's gangrene (FG) incidence and mortality rate in Taiwan and to investigate the contributing factors to such changes. Methods: Between 2002 and 2016, hospitalized FG patients who underwent subsequent surgical intervention were included in this retrospective study. Incidence, outcomes, age-adjusted Charlson Comorbidity Index (ACCI), hospitalization cost, surgical timing, and the number of multidisciplinary specialists involved in the first-line management of FG in each year were collected. Simple linear regression and Pearson correlation coefficient (r) were used for the subsequent analysis. Results: The national cohort enrolled 2183 FG patients from 2002 to 2016 in Taiwan. The age-standardized incidence rate of FG was between 0.4 and 0.8 per 100 000 population, and overall mortality was 7.8% in these 15 years. We illustrated the downward trendline of FG mortality with a 0.62 coefficient of determination. The mortality of FG patients who underwent surgery within 24 h and after 24 h were found to be 8.3 ± 3.9% and 14.6 ± 25.2%, respectively (p = 0.02). The numbers of urologists, anesthesiologists, emergency doctors, and physicians per 100 000 population had a strong negative linear correlation with FG mortality (r = 0.8, p < 0.001). ACCI score had a moderate linear relationship with FG mortality (r = 0.57, p = 0.027). The hospitalization cost showed a weak linear correlation with FG mortality (r = −0.03, p = 0.92). Conclusions: We demonstrated the downward trend of the FG mortality rate in Taiwan from 2002 to 2016. Besides underlying comorbidities and surgical timing, sufficient multidisciplinary specialists are essential for the survival benefit of FG patients in Taiwan experience.
