Abstract:
Hospital discharge and mortality has increasingly become important outcomes in medical research for investigating risk factors of hospital length of stay (LOS). Competing risk setting is a most popular method to analyze multiple events and several ad-hoc methods are more popular when focusing on risk factors for certain event of interest. Thus, the basis for this article was to investigate multiple events of hospital length of stay: discharge and mortality, through two well-known competing risk models: cause specific hazard and sub-distribution, for the dengue patients in Sri Lanka for the years 2007-2008. Moreover, this study concludes that the effect of age, ethnicity, sex, dengue classification, district and platelet count are important to the event of discharge and age, dengue classification, district and platelet count are significant to the event of mortality/death. Also, finally it reveals that both cause specific and subdistribution hazard exhibited similar results under the competing risk setting.
