[Health care-associated infections in teaching hospital Gabriel TOURE]

To study health care-associated infections (HCAI) in teaching hospital Gabriel TOURE.

This was a prospective study of 6 months (from April to September 2016) which included patients admitted to the General Surgery Department, operated or not, except those who had undergone a necrosectomy. The criteria used for the diagnosis of the infection were those of the CDC of Atlanta.

A total of 200 patients were included in the study. Twenty one patients developed IAS that is a frequency of 10.5%. There were 11 men and 10 women with a mean age of 37.7 years with a standard deviation of 17.6 years. Surgical site infection was the most common HCAI (77.3%) followed by urinary tract infection (13.6%) and burn infection (9.1%). The influencing factors were those related to the patients (nutritional status p = 0.004, anemia RR = 3.1 IC p = 0.003 and diabetes), those related to the surgical intervention (the duration of the intervention ≥ 2H, p = 0,0001, the Altemeier class 3 and 4, RR = 4.24, IC p = 0.005, the number of interveners in the blocks ≥7, p = 0.000, the NNISS score 1 and 2 p = 0.0009), invasive procedures (bladder catheter ≥ 4 days p = 0.0000). Escherichia coli was the most isolated microorganism (31.2%) followed by Klebsiella pneumonia and A baumannii (18.7%). The treatment was local (twice-daily dressing with antiseptics), surgical (necrosectomy 16% and re-intervention 10%) and general (adapted to the antibiogram). The consequences of HCAI were an extension of total hospital stay (greater than 7 days) with p = 0.0000, morbidity 3% and mortality 5%.

HCAI remains a concern in our country and globally. They prolong the hospital stay. The implementation of a prevention, control and surveillance program will improve the quality of care by significantly reducing HCAI.
