While the current therapy was changed in 57.4% of these patients,antibiotics were not necessary for 9.8%.Conclusions: Since the most common diagnoses were respiratory and urinary tract orbone and joint prosthesis infections, the ID specialists should have detailed knowledgeof these problems. Usage of antibiotics without ID consultation was prevalent,therefore a continuous educational program is a necessity for healthcare workersin the hospital.# 2005 International Society for Infectious Diseases.

    antimicrobial therapies of these patients wereinitiated by ID specialists.

    During the study period, a total of 395 consultationswere recorded; 121 of them were in the year 2000,142 were in 2001 and 132 were in 2002. One hundredand sixty-eight patients were female (42.5%) and227 were male (57.5%). The mean age of thepatients was 54.66 (SD: 19.29, range 1298).

    The departments requesting most consultationswere Orthopedics (29.6%), Neurology (18.5%), Car-diology (11.8%) and Internal Medicine (10.4%).Departments referred to the ID service for consulta-tions are shown in Table 1. The most common pur-

All consultations were recorded ona form, and the name, age, sex, hospital ward,antibiotic use, purpose of consultation and diagnosisof the patient were included.

    Appropriate antimicrobial therapy was defined asthe use of antibiotics that had in vitro activityagainst the infecting agents isolated or had clini-cally proven efficacy and that were given by anappropriate route and at adequate doses. Empiricantibiotic treatment was evaluated according to thepatients clinical condition, possible source of infec-tion, and place of acquisition. We were not able tocompare the antibiotics initiated before the con-sultation request with the recommendations of localguidelines, as no local guidelines for antibioticsuch as malaria, anthrax, brucellosis or HIV, inci-dences of nosocomial infections and infections ofthe immunocompromised patient have risen drama-tically. The number of infections caused by new, re-emerging or drug-resistant pathogens is growing dayby day, and the increased proportion of hospitalizedpatients with immunodeficiency has resulted in anincrease of severe and invasive infections.14 It hasbecome apparent during the past decades thatinclusion of an ID physician in the consultationprocess can favorably affect antibiotic usage andID specialists have more recently played a leadingrole in instituting programs of antibiotic control.5,6

    In our hospital, up until 2003, there were no restric-tion policies and local guidelines for antibiotic pre-scription. In this study, we aimed to determine thepurposes of consultations and the usage of antibio-tics before and after ID consultation.


    Dokuz Eylul University Hospital is a 750-bed tertiarycare university hospital in Izmir, Turkey. There hasbeen an Infectious Diseases and Clinical Microbiol-ogy Department here since 1997. This departmenthas an inpatient ward where the more usual infec-tions are treated but also supports the other hospi-tal wards as a consultation service. Four IDspecialists perform consultations and the sameteam tracks patient progress on a daily basis untiltermination of the infectious problem. IntensiveCare Unit (ICU) consultations were not includedin the study, because infections in the ICU arefollowed routinely; during the study period theTotal 395 (100)poses for consultation were for diagnosis ofunexplained fever (42.3%), antibiotic choice forbacterial pathogens identified in the patients cul-tures (18.0%), and diagnosis and treatment of prob-able bone and joint prosthesis (8.4%) or surgical siteinfections (8.1%). The most common diagnosesachieved by the ID consultants in the investigatedpatients were pneumonia (16.7%), urinary tractinfections (9.3%), infections of bone or joint pros-thesis (9.1%), and surgical site infections (8.9%)while there was no determined infectious focus in62 patients (15.7%). Of the cases diagnosed aspneumonia, 52 were nosocomial (13.2%) while theremainder were community-acquired cases (3.5%).When the relationship between the purpose of con-sultation and the diagnosis was considered it wasrecognized that the purpose and the final diagnosiswere similar in most of the patients. The mostcommon purposes of consultations and the diag-noses of these patients are shown in Tables 2 and 3.

    It was recognized that microbiological cultures of289 patients had been performed (73.2%) prior to
