          Assessment of the incidence of general infections and ventilator-associated pneumonia in patients undergoing major heart surgery 


Dear Colleague,

The importance of nosocomial infectious complications in patients undergoing major heart surgery (MHS) is evident to all of us. These patients are particularly susceptible to infections such as Ventilator-Associated Pneumonia (VAP), Urinary Tract Infections (UTI) or Catheter-Related Bloodstream Infections (CRI), among others.  Nevertheless, there is little pan European information on these topics when considered on a broad microbiological and clinical basis.

The European Study Group on Nosocomial Infections (ESGNI) and the European Workgroup of Cardiothoracic Intensivists (EWCI) kindly request your participation in three studies addressing these issues: Studies ESGNI 007, 008 and 009.

ESGNI-007 (Assessment of the incidence of infections in patients undergoing MHS in 2001), aims to obtain retrospective information on the overall number of infectious complications of your Unit during 2001 and on the general characteristics of your ICU. We are particularly interested in your policy of diagnosis and therapy of VAP. Completion of ESGNI-007 (see attached protocol) takes only a few minutes and is very important for all of us.

This Study will be complemented by ESGNI-008, entitled "One day prevalence study of risk factors for the development of VAP and other infections after MHS in Europe".  ESGNI-008 is an observational, cross-sectional prevalence study to be carried out on one day. The day of the study will be November 13th, 2002. In this study we request general information about your unit and specific aspects related to  the infectious complications on the study day.

Finally, ESGNI 009 is a one-month (December 2002) incidence study of VAP in patients undergoing MHS. In this study you are requested to include:

a)    General data about your Hospital and Unit in December 2002,
b)    An individual report of every MHS patient admitted to the ICU between December 1st and December 31st.
c)    The protocol addresses with special interest the risk factors, etiology, diagnosis, therapy and outcome of all nosocomial infections suffered by this group of patients during the study-month.

The studies will be carried out as a questionnaire sent to all ICUs caring for MHS patients in all participating European hospitals.

Participants may take part in all three protocols (ideal) or in some of them. We are sending a participation agreement form. The form should be completed and returned to us as soon as possible.

Data may be sent by fax (+34 91 7355446) or by e-mail ( They may also be collected centrally through a link located at the ESGNI web page (, which opens the electronic questionnaires. Electronic submission by means of the ESGNI web page is highly encouraged, since this system allows rapid data entry and processing. Participants will soon be able to find general information about the study and the clinical report forms on the web. Each participating investigator will be contacted via e-mail and will be provided with an exclusive access code that enables data entry and correction. In order to resolve possible doubts during the study period, you can address yourself either to or to
Please note that participants are automatically considered co-authors of the potential publication that reports the results, and will receive early and complete information on all data collected.

These studies receive no funding, therefore only mailing will be supported by the ESGNI /EWCI groups. We kindly request your effort and enthusiasm in this European project.
    On behalf of both groups (ESGNI-EWCI) we thank you for your cooperation and look forward to hearing from you soon.

If you want to participate in either of these studies please read the following instructions. Using this web system allows rapid data entry and processing and is highly encouraged. 


Study ESGNI 007 and 008

In these studies you will need to provide information about your hospital and ICU. Only one questionnaire needs to be filled in, and after you complete it your participation in the specific study finishes. The questionnaire is related to the whole 2001 year for study ESGNI 007, and to the specific date (13th November) for study ESGNI 008.

Study ESGNI 009

When you begin the study you will be asked to provide information about your hospital and ICU during December 2002. After completing this questionnaire, you will be provided with a Hospital ID for authentication when introducing patient data. It is advisable make a note of this ID since you will need it later.

You are now ready to enter  patient data. You will have to complete one form for every patient. It is not necessary to introduce all the patients in one session, you can stop at any moment and connect again later to finish. If you decide to do so, please do not forget your hospital ID , as you will be asked for it the next time you connect to complete more patient forms for that study. If one patient has several episodes of Lower Respiratory Tract Infection you will need to use a different form for every episode, indicating the episode number in the proper field.

If you want to participate in the studies you will need a username and a password . If you have not received one from ESGNI please send an e-mail to specifying that you want to participate in these studies.
