Incidence and risk factors of surgical site infection in a tertiary health institution in Kano, Northwestern Nigeria

Abstract

Surgical site infection (SSI) is the most common complication following surgical procedures. The aim of this study was to determine the incidence and associated risk factors of surgical site infection in a tertiary health institution in Kano, Nigeria.The study was carried out between January 2008 and December 2010. Data was collected in a predesigned questionnaire forms which focused on demographic details, socioeconomic background and lifestyle while the diagnosis, surgical procedure, duration of surgery, prophylactic antibiotics, postoperative antibiotics and co-morbidity were obtained from the patients hospital records. all the patients who underwent surgery in the male and female surgical wards, gynaecology and maternity wards including paediatric wards were enrolled in the study after informed consent of patients or parents in the case of children. all patients were followed up for 30 days for development of surgical site infection. Infected cases were identified using CDC, USA definition for surgical site infections. Out of 2880 patients, 585 (20.3%) were confirmed to be clinically infected (SSI). There were 1,016 (35.3%) males with a mean age of 38.3±16.3 and 1864 females (64.9%), mean age 30.6 ± 12.3yrs. There were 65% Superficial Incisional SSI, 30% deep Incisional SSI and 5% Organ Space SSI. Incidence related to clean, clean contaminated, contaminated and dirty were 5.8%, 30.5%, 40.6%, and 64.8% wounds respectively. Age, anaemia, obesity, number of persons in operating room and duration of surgery were all significantly associated with SSI. Effective infection control measures and good regular surveillance will improve the SSI rate to an acceptable level.

Incidence and predictors of surgical site infection in Ethiopia: prospective cohort

“…The finding was similar to studies done in India 20.09% [21], Nigeria 20.3% [22], India 21.66% [23] and Egypt 22.6% [24]. But, lower compared to studies done in Tanzania 26% [5], India 33.5% [25] and Mekele, Ethiopia 75% [11].…”

Jordanian Nurses’ Knowledge of Preventing Surgical Site Infections in Acute Care Settings

“…The SSI, globally, is considered as a challenging problem that was facing all surgical patients who are acutely ill. The annual incidence rate of SSI in general population was 20.3% in Nigeria [4], 16% in India [5], and 14.7% in Japan [6]. The annual incidence rate of SSI in Jordan among Coronary Artery Bypass Graft Surgery (CABG) patients reached up to 16.8% [7].…”

Bacteriological Profile of Surgical Site Infections and Their Antimicrobial Susceptibility Pattern at Tertiary Care Centre in Kanpur

“…In this study patients more than 50 years of age got infected, which was in contrast to other studies. [10] In the present study surgical site infection was significantly associated with contaminated class of wounds, being the highest (60%) for contaminated surgery, 33.3% for clean-contaminated surgery and 6.6% for clean surgery. While Mundhada AS [4] documented 17.65% clean and 39.39% clean contaminated wound were infected and Lilani et al [7] found 3.03% clean and 22.41% were clean-contaminated surgeries.…”
