Performance of National Nosocomial Infection Surveillance system (NNIS) risk index in predicting surgical site infections

Dr. Vp Singh, Dr. Salamat Khan

Abstract :

Back ground:Hospital acquired infection remains a major health care problem not only in in India but also in other developed countries.No surveillance system exists in the country to predict and stratify the risk of surgical site infections (SSIs). The aim was to know the performance of NNIS composite risk index score system in Indian general surgical patients at career institute of medical sciences hospital,luck now. Method:This is a prospective observational study conducted over a period of 11/2year fromDecember 2014 to July 2016 at Institute of medical science hospitallucknow. All the cases of department general surgery operated either on elective or emergency basis were included. Their ASA category was noted from anaesthetist chart while operative duration and wound class was determined by operating surgeon. Surgical site infection (SSIs) was assessed by surgeon and NNIS risk index score was calculated. All the data were collected complied, analyzed and following observations were made. Results:A total of268 patients were included in the study. Age ranged from3.3–76 years with mean and standard deviation34.44� 19.16 years. Of 268 cases 151 were males and 117were females. Patients were grouped into ASA category score <3 and ≥3. The incidence of SSIs rate of 20.8%, 22.3%, 41.9% and 50.0% were associated with NNIS risk index score 0, 1, 2 and 3 respectively. There was increasing trend of SSIs with rising NNIS risk index score from 0–3 Conclusion: The findings of the present study validate that NNIS risk index is good predictor of SSIs in general surgical cases. Thus it can be applied for assessment of risk for SSIs in general surgical cases
