Background The aim of this study was to analyse the trends of mortality and causes of death among HIV‐infected patients in Taiwan from 1984 to 2005. Methods Registered data and death certificates for HIV‐infected patients from Taiwan Centers for Disease Control were reviewed. Mortality rate and causes of deaths were compared among patients whose HIV diagnosis was made in three different study periods: before the introduction of highly active antiretroviral therapy (HAART) (pre‐HAART: from 1 January 1984 to 31 March 1997), in the early HAART period (from 1 April 1997 to 31 December 2001), and in the late HAART period (from 1 January 2002 to 31 December 2005). A subgroup of 1161 HIV‐infected patients (11.4%) followed at a university hospital were analysed to investigate the trends of and risk factors for mortality. Results For 10 162 HIV‐infected patients with a mean follow‐up of 1.97 years, the mortality rate of HIV‐infected patients declined from 10.2 deaths per 100 person‐years (PY) in the pre‐HAART period to 6.5 deaths and 3.7 deaths per 100 PY in the early and late HAART periods, respectively ( P <0.0001). For the 1161 patients followed at a university hospital (66.8% with CD4 count <200 cells/μL), HAART reduced mortality by 89% in multivariate analysis, and the adjusted hazard ratio for death was 0.28 (95% confidence interval 0.24, 0.33) in patients enrolled in the late HAART period compared with those in the pre‐HAART period. Seventy‐six per cent of the deaths in the pre‐HAART period were attributable to AIDS‐defining conditions, compared with 36% in the late HAART period ( P <0.0001). The leading causes of non‐AIDS‐related deaths were sepsis (14.7%) and accidental death (8.3%), both of which increased significantly throughout the three study periods. Compared with patients acquiring HIV infection through sexual contact, injecting drug users were more likely to die from non‐AIDS‐related causes. Conclusions The mortality of HIV‐infected patients declined significantly after the introduction of HAART in Taiwan. In the HAART era, AIDS‐related deaths decreased significantly while deaths from non‐AIDS‐related conditions increased.
