Background: The survival in Iranian HIV/AIDS patients based on data from Iran National HIV/AIDS Case Registry System has not been evaluated. This study assessed the survival rates and associated factors among people living with HIV/AIDS in Iran. Materials and Methods: The population in this observational study included 32168 patients diagnosed with HIV/AIDS registered in Iran disease registry system between 1986 and 31 December 2015. Data until June 2016 (the cutoff date of our last data linkage) were investigated to estimate survival and related factors following HIV diagnosis. Results: Of registered patients, 17.7% were diagnosed at AIDS stage. By June 2016, 27.2% of study population progressed to AIDS, and 8081 (25.1%) of patients died. The survival rate was 88%, 85%, 77%, and 67% for 1, 2, 5, and 10 years, respectively. Cumulative proportion surviving was significantly lower in males than in females (P = 0.0001). A higher rate of survival was seen in female patients, who diagnosed after 2010, infected in sexual route, and had CD4 cell count more than 500, nonconfected patients with tuberculosis (TB), and those who received antiretroviral therapy (ART). Based on multivariate model, the mortality risk in female patients, those with CD4 cell count more than 500, patients who received ART, and those with TB and injection drug uses (IDUs) was higher. Conclusion: The survival in studied patients increased in recent time periods, and ART reduced AIDS-related mortality in these patients. The survival can be increased by focus on improvements in patient care among male patients, IDUs, and patients with TB coinfection.
