Interaction between the microbiology laboratory and clinician: what the microbiologist can provide

The work of the clinical microbiologist comprises three major areas: diagnostic work in the laboratory, advice to clinicians about treatment of infected patients, and infection control. By clinical alertness, either from work in the laboratory or from clinical contacts, the microbiologist may contribute to the recognition of hospital outbreaks. The microbiologist plays a key role in implementing a restrictive antibiotic policy in hospital. Experience shows that a close personal contact with clinicians in the daily treatment of patients is the most efficient way to ensure a rational use of antibiotics and keep the consumption low. Other important measures include the elaboration of antibiotic guidelines and performance of audits. On basis of periodic summaries of laboratory data and data on antibiotic consumption, the microbiologist can keep the clinicians informed about antibiotic resistance and compliance with the antibiotic guidelines. In addition to informal contacts, the microbiologist also interacts with clinicians through participation in infection control and drug and therapeutic committees.
