infection adjudication
Infection Adjudication
  • Based on the microbiology and antibiotic data entered, REDCAP will automatically trigger suspicions of newly acquired infections
  • Suspicions MUST be adjudicated by Site Investigator or MD delegate
  • REDCAP will generate a table that will guide and assist the Site Investigator/Research Coordinator through the various steps
how to start
How to Start?
  • Log in to REDCAP using assigned username and password
  • Click on the “My Database” tab, select TOP-UP. Click on the “Infection Adjudication” link
  • You will be directed to the following window showing the patients that require adjudication and how many suspicions of infection each have
  • Click on the patient ID
adjudication table baseline daily data
Adjudication Table: baseline, daily data

Infection adjudication table will show up listing:

  • baseline/outcome information at the top
  • daily data elements, micro and antibiotics
  • Suspicions of infection (Newly Acquired Infections)
microbiology and antibiotic forms
Microbiology and Antibiotic Forms
  • Click on the antibiotic or organism names to view the corresponding antibiotic/microbiology forms

Click to open a window with the Day 1 Antibiotic form for Metronidazole

Click to open a window with the Day 3 Microbiology form for Escherichias.p. - coli

adjudication table suspicions of infection
Adjudication Table: suspicions of infection

You will have 3 options to enter in the NEWLY ACQUIRED INFECTION column:

  • This is a newly acquired infection
  • This is not a newly acquired infection
  • This is a previously adjudicated infection
a newly acquired infection
a) Newly acquired infection
  • Pick this option if the clinical suspicion of infection is considered to be a newly acquired infection.
  • Assign a Category of Infection, then the degree of certainty of the infection using the definition from CRF Appendix 9
  • For example, on study day 9 the patient is febrile, has an elevated WBC, CXR reveals a new infiltrate. An endotracheal aspirate specimen was sent for culture, S. aureus is identified. The infection should be adjudicated as follows:

Click to open a window describing the categories and the degrees of certainty

b not a newly acquired infection
b) NOT a newly acquired infection
  • Pick this option if the clinical suspicion of infection is not considered to be an infection.
  • Assign the degree of certainty of the infection using CRF Appendix 10
  • For example, On study day 17 a blood culture indicates the presence of Staph Epidermis. There are no other clinical indicators of infection (i.e. SIRS). A repeat culture is negative. The initial positive culture is thought to be a contaminant. The infection should be adjudicated as follows:

Click to open a window describing the degrees of certainty

c previously adjudicated infection
c) Previously adjudicated infection
  • Pick this option if this clinical suspicion of infection is associated with an infection already adjudicated.
  • Indicate the day and the suspicion # of the associated previously adjudicated infection.
  • Infections that occur within the first 72 hrs of ICU admission are not to be considered newly acquired infections, however, these may be related to suspicions later.
    • If the suspicion of infection was due to an infection that occurred in the first 72 hours after ICU admission, select “Baseline Infection”.
c previously adjudicated infection1
c) Previously adjudicated infection
  • For example, on study day 19 the patient is febrile, has an elevated WBC and CXR reveals a new infiltrate. An endotracheal aspirate specimen was sent for culture, S. aureus is identified.
  • On study day 20 an antibiotic was initiated to treat the S. aureus.
  • The clinical suspicion triggered on study day 20 with the initiation of an antibiotic is related to a previously adjudicated infection.

infection id s
Infection ID #’s

All suspicions of infection will be assigned unique infection identification number followed by the study day it was entered on

Infection ID #s will never be repeated

Infection identification numbers will be sequential unless a microbiology and/or antibiotic form was changed/added AFTER adjudications have been saved

15

site infection responses completed
Site: infection responses completed

When done click SAVE & COMPLETED at bottom of page if you have completed ALL the infection adjudication for this chart

SAVE if wish to return

Both buttons will initiate data checks

There will be a confirmation for either a “save” or a “save and complete” at the top of the table

central adjudicator
Central Adjudicator
  • At stage 4a, the central adjudicator will review each suspicion of infection and determine if s/he agrees or disagrees with the site’s suspicion of infections
  • Central adjudicator is assigned by CERU
site response to central adjudication
Site response to Central adjudication
  • Every few weeks, an email on adjudications requiring your attention (including those that have been centrally adjudicated) will be sent to you
  • Log in using your USERNAME and PASSWORD

note sites responses removed
NOTE: Sites responses removed

This was removed because the Central Adjudicator disagreed with Infection ID #1

The sites response

was not changed

All adjudications that the central adjudicator has disagreed to will automatically remove the sites response upon completion

All adjudications that the central adjudicator agreed to will not be changed

comments
Comments
  • Click to see your old response and an explanation why the central adjudicatordisagreed in a new window
  • The number in brackets indicates the number of comments that have been recorded
  • Use the comments window to track the discussion and the changes to suspicion of infection
  • Click to add additional comments

site response to central adjudication2
Site Response to Central adjudication

The CENTRAL ADJUDICATOR RESPONSE column will show either as an agree or a disagree (with a new response and the reasoning why in the comments)

You must re-adjudicate all adjudications that the central disagreed to

You will have 2 options to enter in the NEWLY ACQUIRED INFECTION column: Agree OR Disagree

slide30

Site Response to Central adjudication

  • OPTION 2:

Select this if you disagree with any aspect of the determination made by the central (such as the presence of infection, the category of infection and/or the degree of certainty). Re-adjudicate using the following options:

    • This is a newly acquired infection
    • This is not a newly acquired infection
    • This is a previously adjudicated infection
  • OPTION 1:

Select this if you agree with the determination made by the Central. If so, the following options stay disabled

    • This is a newly acquired infection
    • This is not a newly acquired infection
    • This is a previously adjudicated infection

30

slide31

Site Response to Central adjudication

  • If you disagree, you must save a comment explaining your reasoning.
  • All adjudications that you disagree to will automatically remove the centrals response upon completion
incorrect response
Incorrect Response
  • Since the centralresponse is automatically removed when you disagree (eg infection ID #1), any adjudication that refers to it (eg infection ID #2) will be removed as well
  • An error will trigger if you try to agree with a response that will be removed

This will be removed because the you disagreed with Infection ID #1

This will be also be removed because it refers to Infection ID #1 which will be removed

You can not agree to a response that will be removed

32

correct response
Correct Response
  • If infection ID # 2 is a previous infection to ID #1, you must disagree and select that the suspicion is a previous adjudicated to your response

You must select disagree and select previous to your (site) response

33

site to complete final adjudication
Site: to complete final adjudication

Once adjudication is done, press

The status will go back to Stage 4a for the central adjudicator to review

The central adjudicator will have the opportunity to agree/disagree to adjudications you disagreed with

This process will continue between site and central adjudicator until there is consensus for all the adjudications

Once both adjudicators agree on all the responses, adjudication will be complete and the patient will automatically be set to stage 5

If the site disagrees with any of the central changes or has made any changes

If the central adjudicator agrees with all of the site adjudicators

Central disagrees with at least one adjudication

Stage 4b

Site adjudicator reviews each adjudication and either agrees or disagrees with centrals adjudicators changes

Both adjudicators agree on all suspicions of infection

Investigators Confirmation

site investigator
Site Investigator

Remember the Site Investigator/MD delegate must determine the presence or absence of infection, the categories of infection and the degree of certainty

Upon completion at stage 5, print the adjudication table (right click and print) and have the Site Investigator sign it for source verification purposes

data checks
Data Checks
  • Whenever the or the buttons are clicked, they will run data checks.
  • There are 4 types of checks
    • Partial responses
    • Missing responses
    • Missing Explanation
1 partial responses check
1) Partial responses Check
  • Partial responses can not be saved.
    • For example, the category of infection and the degree of certainty must be completed for newly acquired infections to be saved
    • This applies to both and

38

2 missing responses check
2) Missing responses check
  • Missing responses can be saved only with
    • For example, infection ID # 1-4 has been completed but # 5 has not. You can save infections 1-4 with the button but you will not be allowed to choose until infection #5 has been filled out

39

3 missing explanation check
3) Missing Explanation Check
  • If you disagree with the central adjudicators response, you must write a reason in the comment box
    • This applies to both and
