A Prospective Study of Surgical Site Infection at Vasavi Hospital, Bangalore, Karnataka, India

Abstract

Introduction: Surgical Site Infection (SSI) is an infection which develops within 30 days after a surgical procedure or one year after the placement of an implant and the infection appears to be associated with surgery. SSI is related with complications like increased readmission rates, length of stay and cost. Aim: To find out the incidence rate of SSI, aetiology and their antibiogram. Materials and Methods: A prospective study of 947 patients (454 male and 493 female) who underwent surgery at Vasavi Hospital, Bangalore, Karnataka, India, from February to December 2019 formed the study group. Age, sex, type of surgery, month wise, section wise, duration of surgery, prophylaxis given, elective or emergency etc., were noted. Pathogen isolated from SSI cases was identified and their antibiogram were recorded. Results: Of the 947 patients, 239 (25.24%) belonged to General Surgery, 301 (31.78%) Orthopaedics, 187 (19.75%) Gynaecology, 124 (13.09%) Urology, 40 (4.22%) ENT, 20 (2.11%) Oncology and 36 (3.80%) Miscellaneous. SSI rate in the present study was 0.21%. Two patients (females) aged 66 and 33 years developed deep infection at the site of incision, with purulent discharge that was operated from orthopaedic department. Pathogens isolated were Staphylococcus aureus (MSSA) and Streptococcus pyogenes. Isolates were sensitive to routinely used antibiotics. Conclusion: SSI rate of 0.21% was been achieved by stringent quality control measures, training of hospital staff and continuous surveillance of infections.
