This document is an executive summary of the APSIC Guide for Prevention of Central Line Associated Bloodstream Infections (CLABSI). It describes key evidence-based care components of the Central Line Insertion and Maintenance Bundles and its implementation using the quality improvement methodology, namely the Plan-Do-Study-Act (PDSA) methodology involving multidisciplinary process and stakeholders. Monitoring of improvement over time with timely feedback to stakeholders is a key component to ensure the success of implementing best practices. A surveillance program is recommended to monitor outcomes and adherence to evidence-based central line insertion and maintenance practices (compliance rate) and identify quality improvement opportunities and strategically targeting interventions for the reduction of CLABSI.

Objectives: To carry out a retrospective study on Acinetobacter baumannii isolates from various clinical samples in a tertiary care hospital in India and analyze its epidemiology, antibiotic susceptibility patterns, pathogenic potential and nosocomial status. Materials and methods: The clinical specimens over a period of 14 months from December 2008 to January 2010 were analyzed and the A.baumannii isolates obtained by an automated identification system (Vitek 2 Compact) were segregated for further study. Their antibiograms were studied and a clinical correlation was made to assess their pathogenic status and mode of acquisition. Further, the nosocomial infections acquired during this period were studied and the contribution made by A.baumannii was calculated to assess its nosocomial status. Results: A.baumannii was isolated in 155 samples out of 1632 gram negative isolates (9.4% prevalence) from the entire hospital. Maximum isolates were from respiratory secretions (57.4%) followed by blood (23.8%). Prevalence of A.baumannii rose to 22.7% (119 out of 525) in intensive care unit (ICU) and 65 isolates (54.6%) proved to be pathogenic. A.baumannii contributed to 30.4% ventilator associated pneumonia, 35.2% Catheter Associated Blood Stream Infections, 12.5% Surgical Site Infections and 2.94% Catheter Associated Urinary Tract Infections. Overall resistance of A.baumannii towards carbapenems was 90% from all hospital isolates. ICU isolates showed higher resistance (93.2%) as compared to Inpatient Department (82.7%) and Outpatient Department (57.1%). Conclusion: In this study, A.baumannii isolates showed a pathogenic potential of around 54.6% and a majority were found to be carbapenem resistant. We must be cognizant of the fact that all A.baumannii isolations doesn't necessarily mean infection and antibiotics should only be given in clinically proven infections.

The most common labour and cost effective infection control measures as revealed by the supervision programme were adherence to the urinary catheter checklist components (indication for catheter insertion and change, asepsis maintenance during and after the catheter insertion and avoiding urine reflux) and hand hygiene practices, whereas bladder irrigation and practising perineal cleaning thrice a day were unnecessary measures.

Our study showed that the implementation of a multidimensional infection control strategy is associated with a significant reduction in the CAUTI rate in AICUs from developing countries.

Despite a lower device use ratio in our ICUs, our device-associated healthcare-associated infection rates are higher than National Healthcare Safety Network, but lower than International Nosocomial Infection Control Consortium Report.

Implementing the six components of the INICC approach simultaneously was associated with a significant reduction in the CLABSI rate in India, which remained stable during 36 months of follow-up.

BackgroundThe objective of this study was to assess the impact of antimicrobial stewardship programs on the multidrug resistance patterns of bacterial isolates. The study comprised an initial retrospective analysis of multidrug resistance in bacterial isolates for one year (July 2007-June 2008) followed by prospective evaluation of the impact of Antimicrobial Stewardship programs on resistance for two years and nine months (July 2008-March 2011).SettingA 300-bed tertiary care private hospital in Gurgaon, Haryana (India)FindingsMethodsStudy Design• July 2007 to June 2008: Resistance patterns of bacterial isolates were studied.• July 2008: Phase I intervention programme Implementation of an antibiotic policy in the hospital.• July 2008 to June 2010: Assessment of the impact of the Phase I intervention programme.• July 2010 to March 2011: Phase II intervention programme: Formation and effective functioning of the antimicrobial stewardship committee. Statistical correlation of the Defined daily dose (DDD) for prescribed drugs with the antimicrobial resistance of Gram negatives.ResultsPhase I intervention programme (July 2008) resulted in a decrease of 4.47% in ESBLs (E.coli and Klebsiella) and a significant decrease of 40.8% in carbapenem-resistant Pseudomonas. Phase II intervention (July 2010) brought a significant reduction (24.7%) in carbapenem-resistant Pseudomonas. However, the resistance in the other Gram negatives (E.coli, Klebsiella, and Acinetobacter) rose and then stabilized. A positive correlation was observed in Pseudomonas and Acinetobacter with carbapenems and cefoperazone-sulbactam.Piperacillin-tazobactam showed a positive correlation with Acinetobacter only. E.coli and Klebsiella showed positive correlation with cefoparazone-sulbactam and piperacillin-tazobactam.ConclusionAn antimicrobial stewardship programme with sustained and multifaceted efforts is essential to promote the judicious use of antibiotics.
