WHONET Documentation

  1. 1. Need for WHONET Documentation *T.V.Rao, C.Aher, Deepa Babin, Deepthy Sooryadas Department of Microbiology Travancore Medical College, Kollam Kerala, India Antibiotics are considered as strength of theModern Medicine, and helped the humans to progress to thepresent stage, along with several other advances in Medicine.At present, the Antibiotics are used for needy patients andmisused too when there is no need for an antibioticprescription. Drug resistance develops naturally, but carelesspractices in drug supply and use are hastening it unnecessarily,we certainly need a system to document the results of antibioticsensitivity and resistance patterns arising in our Institution,which can be documented with WHONET.WHONET is free Windows-based database softwaredeveloped for the management and analysis of microbiologylaboratory data with a special focus on the analysis ofantimicrobial susceptibility test results. These tools enablemicrobiology laboratory to put its test results into a databaseand conduct analysis to support local infection control andantibiotic usage at our Hospital
  2. 2. The software has been developed since 1989 by the WHOCollaborating Centre for Surveillance of AntimicrobialResistance based at the Brigham and Womens Hospital inBoston, and is used by clinical, public health, veterinary, andfood laboratories in over 90 countries to support local andnational surveillance programs.Laboratories can also upload files created by WHONET, tofeed into national or other multi-centre surveillance networksand to strengthen our Drug policy. Such surveillance programsare now in place in many countries and part of Accreditationstandards in our country.How we can Progress with WHONETWe can enhance the local data for local needs: clinicaldecision support, antimicrobial use policy, infection control andoutbreak detection, identifying laboratory test performance, andcharacterization of local microbial and resistance epidemiologyAnd to promote local, national, regional, and globalcollaborations through the exchange of data and sharing ofexperiences.The WHONET experience suggests that pattern of drugresistance data can be collected and analysed in resource-
  3. 3. constrained settings, using core microbiology, if locallaboratories are given appropriate support. Strengthening theselaboratories is therefore a potentially cost-effective Contributionto both treating drug resistant disease and preventing its furtherspread.Microbiologists, Clinicians and Infection control workers mayuse its software to enhance monitoring of drug resistance intheir hospitals and communities and to merge their files intonational, regional, and global networks for surveillance of drugresistance. WHONET can also analyse stored data. From asingle screen, a WHONET user selects the type of analysis torun, the species of bacteria to analyse, the subsets of isolatesto include (e.g., all, isolates from urine, blood , and isolatesresistant to Cephalosporin’s, Carbapenems or any other drugindividually and from certain locations in outpatients and anywards like ICCU’s Medicine, Surgery or any other speciality)Every patient in our Hospital or its community carries a complexbacterial ecosystem and each patient care unit within the centreand ultimately the centre itself may be seen as an aggregatedecosystem. Resistance genes and the strains they makeresistant move through these systems, selectively acceleratedby specific antimicrobial agents given to specific patients and
  4. 4. retarded by infection control practices. Both strategic and day-to-day management of those practices and of the selection ofthose agents need optimal, current information about thelinkages of the resistance genes and the deployment of thestrains. The Microbiology laboratory at our Hospital also needscontinuing analysis of its susceptibility test and quality controlresults. Each laboratory tests hundreds of differentcombinations of bacterial species and antimicrobial agents.Variations in the usual distributions of measurements for any ofthe combinations, and particularly of those that impinge uponbreakpoints may signal either problems in test performance ornew types of resistance.A present WHONET helps our HospitalCreates profile of the Bacterial Infections at our Hospital.Helps to know the Antibiograms pattern of the different isolates.Trends in MRSA, and patterns of drug resistance in severalGram negative bacterial strains.We can alert the physicians on uncommon, clinically importantbacterial pathogens.Helps our faculty to present data at academic associations andin publishing papers as per editorial guidelines.However it needs greater cooperation of all Clinicians to buildthe system to our Hospital needs,The protocols can be integrated into the Antibiotic policy
