Perioperative outcomes in human immunodeficiency virus-infected patients – the PRO HIV study

It is estimated that a quarter of patients with HIV/AIDS undergo at least one surgical procedure in their life time. Surgical outcomes in these patients from developing countries are poorly characterized and surgeons are often concerned about poor surgical outcomes, especially when their CD4 cell counts are less than 200 cells/µl. This study evaluated the surgical outcomes of HIV-infected patients undergoing various surgical procedures over a six-year period in a large tertiary care hospital from South India. Two hundred and ninety-three patients underwent 374 surgical procedures during the study period. The median duration of HIV prior to surgery was 1.9 years (range 0–18.8 years). Two-thirds (58%) were on highly active antiretroviral therapy (HAART) at the time of surgery with the median duration of this treatment being 38 months (n = 194). About one-third (35%) of surgical procedures were performed as an emergency. Abdomino-pelvic surgeries were the most common (225, 60%). Adverse surgical outcome defined as death or post-operative infection was seen in 25 (6.6%). The post-operative infection rate was 5% (20/374). The most common of these was surgical site infection observed in nine (60%) followed by pneumonia in five patients (33%) and urinary tract infection in one patient. Day 30 mortality was 2% (n = 8) and a quarter of these were reported to be related to post-operative infectious complications. On multivariate analysis, only preoperative haemoglobin of less than 10 g/dl was significantly associated with a poor surgical outcome. HIV-related parameters such as CD4 cell counts, duration of HIV infection and HAART regimen did not seem to contribute towards an adverse surgical outcome.
