Introduction: Infections that occur in the wound created by an invasive surgical procedure are generally referred to as surgical site infections (SSIs). SSIs are one of the most important causes of healthcare-associated infections (HCAIs). The prevalence studies tend to underestimate SSI because many of these infections occur after the patient has been discharged from hospital. SSIs are associated with considerable morbidity and it has been reported that over one-third of postoperative deaths are related, at least in part, to SSI (Eriksen HM et. al., 2003). However, it is important to recognise that SSIs can range from a relatively trivial wound discharge with no other complications to a life-threatening condition. Other clinical outcomes of SSIs include poor scars that are cosmetically unacceptable, such as those that are spreading, hypertrophic or keloid, persistent pain and itching, restriction of movement, particularly when over joints, and a significant impact on emotional wellbeing. The development of an SSI depends on contamination of the wound site at the end of a surgical procedure and specifically relates to the pathogenicity and inoculum of microorganisms present, balanced against the host’s immune response. Methodology: This was a prospective observational study conducted at Jinnah hospital Lahore during the time period between January 2019 and December 2019. The study population consisted of 200 patients who underwent surgery were included. Operated patients were followed up regularly, during the post-operative period. Results: The patient having haemoglobin less than 10 gm/dl) had 35.7% of infected surgical site cases. The patients who had loss of more than 6 Kg body weight was considered to be malnourished had 25% of infected cases Smoking (more than 10 cigarettes/day) had 40% increased incidence of wound infected cases. Diabetes mellitus patient had 48.4% of operation site infected wound whereas malignancy had 54.5 cases of post operation surgical wound infection. Chronic illnesses such as ischemic heart disease and stroke has 55.5% of surgical site infection. Other cases which include obesity (more than 10% of ideal body weight), hypertension, urinary tract infection and dehydration account for 61.9% increased incidence of wound infection post operation.
