Brief Summary

DetermInants of Antimicrobial use aNd de-escalAtion in critical care (DIANA study), is a multicenter, international, prospective, observational cohort study, aiming to describe the rate of de-escalation as well as the associated outcome and the empirical antibiotic therapy for infections at the intensive care unit.

Outcome Measures

Primary Outcomes (2)

  • Number of patients in which the empirical antibiotic therapy is de-escalated

    Included patients will be monitored for 28 days. This is the number of patients in which the empirical antibiotic therapy is de-escalated during the time of observation.

    28 days

  • Proportion of patients with clinical cure at day 7 in de-escalated patients versus non-deescalated patients

    This is the proportion of patients in which the infection under study is clinically cured, which is defined as: 'disappearance of all signs and symptoms related to the infection under study' in de-escalated versus non-deescalated patients.

    7 days

Secondary Outcomes (11)

  • Antibiotics used in empirical antimicrobial therapy in critically ill patients

    28 days

  • Proportion of appropriate empirical antibiotic therapy in critically ill patients

    28 days

  • Antibiotics used in definitive antimicrobial therapy in critically ill patients

    28 days

  • Duration of antimicrobial treatment for the infection under study in de-escalated patients versus non-deescalated patients

    28 days

  • Duration of hospitalization on the intensive care unit in de-escalated patients versus non-deescalated patients

    28 days

  • +6 more secondary outcomes

Study Arms (1)

Critically ill patients with infection

Critically ill adult patients receiving empirical antibiotic therapy for suspected or confirmed infections at the Intensive Care Unit

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

All patients admitted to the intensive care unit during a 2-week period between October 2016 and December 2017. Participating centers can select the weeks of participation based on local considerations and staff availability.All consecutive patients that are eligible according to inclusion and exclusion criteria should be included in the study.

You may qualify if:

  • Age 18 years or older.
  • Patient is admitted to an ICU and has an anticipated need of ICU support of at least 48 hours.
  • Patient has a suspected or confirmed bacterial infection (community-, healthcare-, hospital- or ICU-acquired).
  • Empirical antibiotic therapy is started for this infection at any time in the ICU or no more than 24 hours prior to ICU admission. If the initial antibiotic therapy is considered inadequate and another empirical scheme is chosen at ICU admission, this will be the empirical antibiotic of the study.
  • Causative pathogen and susceptibility are unidentified at time of initiation of the antibiotic therapy (Gram staining results may be known).
  • Signed informed consent (if required by local ethics committee).
