[HIV antibody detection results in patients seeking medical care in Peking Union Medical College Hospital, 2003-2014].

Objective: To better understand the infection status of HIV in the patients seeking medical care in Peking Union Medical College Hospital. Methods: The HIV detection data of the patients in the hospital from 2003-2014 were collected for a statistical analysis with software SPSS 19.0. Results: A total of 715 421 patients were screened, and 1 012 (0.14%) patients were HIV positive, and HIV infection were confirmed in 776 (0.11%) patients by Western Blot testing. The detection rate of HIV infection increased from 0.05% in 2003 to 0.17% in 2014 (trend χ(2)=66.83 , P=0.000), and the increase during 2012-2014 was obvious. Of the 776 newly diagnosed HIV-infected individuals, 631 (81.31%) were men and 145 (18.69%) were women. The percentage of the males infected with HIV increased from 50.00% to 90.26% (trend χ(2)=58.41, P=0.000). The median age was 36 years (interquartile range: 27-43), and the age group 18-50 years were mostly affected. In the 776 patients infected with HIV, 634 (81.70% ) were infected through sexual contacts, and the proportion of sexual transmissions increased with year (trend χ(2)=126.38, P=0.000). The proportion of infected men who have sex with men (MSM) increased from 0% in 2003 to 53.90% in 2014 (trend χ(2)=11.96, P=0.001), similar to the trend in western countries. The proportion of infected patients who were not married increased from 18.75% to 42.21% (trend χ(2)=43.74, P=0.000). The top three source departments of HIV/AIDS cases were internal medicine (51.03%), emergency room (18.30%) and dermatology (13.53%). The proportion of the HIV/AIDS patients from department of gynecology and obstetrics declined from 18.75% in 2003 to 2.60% in 2014. No HIV/AIDS patients were detected in department of surgery, department of otorhinolaryngology, department of ophthalmology, department of stomatology and health examination center in 2003, but 14 cases (9.10%), 11 cases (7.14%) and 4 cases (2.60%) were detected in these departments respectively in 2014. Conclusion: The HIV detection rate increased with year in Peking Union Medical College Hospital, suggesting the necessity of strengthened HIV test in general hospitals. MSM are the population at high risk, to whom more attention should be paid.
