Background: Healthcare-associated infections (HAIs) are a major global threat to patient safety. Systematic surveillance is crucial for understanding HAI rates and antimicrobial resistance trends and to guide infection prevention and control (IPC) activities based on local epidemiology. In India, no standardized national HAI surveillance system was in place before 2017. Methods: Public and private hospitals from across 21 states in India were recruited to participate in an HAI surveillance network. Baseline assessments followed by trainings ensured that basic microbiology and IPC implementation capacity existed at all sites. Standardized surveillance protocols for central-line–associated bloodstream infections (CLABSIs) and catheter-associated urinary tract infections (CAUTIs) were modified from the NHSN for the Indian context. IPC nurses were trained to implement surveillance protocols. Data were reported through a locally developed web portal. Standardized external data quality checks were performed to assure data quality. Results: Between May 2017 and April 2019, 109 ICUs from 37 hospitals (29 public and 8 private) enrolled in the network, of which 33 were teaching hospitals with >500 beds. The network recorded 679,109 patient days, 212,081 central-line days, and 387,092 urinary catheter days. Overall, 4,301 bloodstream infection (BSI) events and 1,402 urinary tract infection (UTI) events were reported. The network CLABSI rate was 9.4 per 1,000 central-line days and the CAUTI rate was 3.4 per 1,000 catheter days. The central-line utilization ratio was 0.31 and the urinary catheter utilization ratio was 0.57. Moreover, 3,542 (73%) of 4,742 pathogens reported from BSIs and 868 (53%) of 1,644 pathogens reported from UTIs were gram negative. Also, 1,680 (26.3%) of all 6,386 pathogens reported were Enterobacteriaceae. Of 1,486 Enterobacteriaceae with complete antibiotic susceptibility testing data reported, 832 (57%) were carbapenem resistant. Of 951 Enterobacteriaceae subjected to colistin broth microdilution testing, 62 (7%) were colistin resistant. The surveillance platform identified 2 separate hospital-level HAI outbreaks; one caused by colistin-resistant K. pneumoniae and another due to Burkholderia cepacia. Phased expansion of surveillance to additional hospitals continues. Conclusions: HAI surveillance was successfully implemented across a national network of diverse hospitals using modified NHSN protocols. Surveillance data are being used to understand HAI burden and trends at the facility and national levels, to inform public policy, and to direct efforts to implement effective hospital IPC activities. This network approach to HAI surveillance may provide lessons to other countries or contexts with limited surveillance capacity.Funding: NoneDisclosures: None
Introduction: Blood cultures play an important role in the early diagnosis of sepsis and its management. Early detection of pathogens in Blood Stream Infections (BSI) and their Antimicrobial Susceptibility Testing (AST) pattern, plays a vital role in the diagnosis of sepsis and is important for guidance of appropriate therapy. Aim: To evaluate the accuracy of shortly incubated blood cultures in comparison with standard method for an early Identification (ID) and AST. Materials and Methods: This was a prospective observational study undertaken from July 2015-June 2016 at Nizam’s Institute of Medical Sciences, Hyderabad, Telangana, India. The blood cultures were loaded in the BacT/Alert system. A total of 92 patients with two sets of blood cultures that flagged positive within 24 hours of collection were included in the study. Grams stain and subcultures of the broths were done. The culture plates were examined after four hours and then at hourly intervals for the presence of growth. Once the growth was sufficient it was processed immediately for ID and AST by Vitek 2C. Incubation of the plates was continued for the rest of the 24 hours at 37oC and was processed again. The mean time for detection were compared between short and standard cultures. Results: Gram negative pathogens were the predominant organisms isolated in 82/92 (89%) followed by Gram positive in 10/92 (10%). The short and standard cultures had comparable results with respect to ID of the isolates. But, the AST results were comparable only in 88/92 (95.6%) patients. Of the remaining four patients, the AST showed Very Major Error (VME) in 3 (3.3%) patients and Major Error (ME) in 1 (1.08%) patient. Conclusion: Short incubation of cultures enabled earliest ID and AST of the isolates from blood cultures than standard incubation
