### HAI data

HAI, microorganism and antimicrobial resistance data are entered through the Patients - Healthcare-associated infections (HAI) form. The fields in the form are described in Table 17.

To enter HAI, microorganism and antimicrobial resistance data:

1. Click the HAI button in the ICU Surveillance/patients General tab to open the HAI form.

2. Specify values for the fields in the ICU surveillance/patients HAI General tab. Descriptions of the variables in this form are given in Table 17 below. Mandatory fields are indicated by a red asterisk *. Required fields are indicated by a black asterisk *.

3. Enter the Case definition code and Date of infection onset data (mandatory).

4. Select the relevant device status from the drop-down list.

5. Click the Save icon or press Ctrl+S.

If any mandatory or required data field is empty when you save, e.g. because you do not yet have the data, an error and/or warning message is shown and the field label is highlighted as a reminder - in red for a mandatory field (you cannot save) or blue for a required field. See Understanding reported errors.

Once the HAI record is saved, the microorganism sub-form is activated.

6. Click on the drop-down list in the Microorganism field or enter the first letters of a microorganism to select a microorganism.

Once the organism is selected, the corresponding AMR markers are automatically displayed.

7. Enter the susceptibility results in the corresponding SIR1, SIR2, etc. fields.

8. Select the relationship of the HAI to the patient outcome from the drop-down list at the bottom of the form.

9. Click the Save icon or press Ctrl+S.

Table 17: ICU patient HAIs General tab variables

Variable | Description
Header section | See Table 15.
Case definition code (Site of Infection) * | Site of infection according the case definition (including subcategory), taking into account signs and symptoms of the entire infection episode (not just day one of the HAI). See Chapter 3 for case definitions. BSI = Bloodstream infection; PN = Pneumonia (unknown subcategory); PN1 = Pneumonia (protected sample + quantitative culture); PN2 = Pneumonia (non-protected sample (ETA) + quantitative culture); PN3 = Pneumonia (alternative microbiological criteria); PN4 = Pneumonia (sputum bacteriology or non-quantitative ETA); PN5 = Pneumonia (no microbiology); UTI = Symptomatic urinary tract infection (unknown subcategory); UTI-A = Symptomatic urinary tract infection (microbiologically confirmed); UTI-B = Symptomatic urinary tract infection (not microbiologically confirmed); CRI1-CVC = CVC-related infection (local); CRI2-CVC = CVC-related infection (generalised no positive haemoculture); CRI3-CVC = CVC-related infection (generalised with positive haemoculture). If (optional) catheter-related infections (CRIs) are included in the surveillance, report a CVC-related BSI corresponding to the case definition of CRI3-CVC as CRI3-CVC (do not report twice).
Date of infection onset * | Date of onset of symptoms or, if unknown, date treatment was started or date first diagnostic examination was done.
Relevant device in situ before onset * | Relevant invasive device was present (even intermittently) in the 48 hours preceding the infection (7 days for UTIs): intubation for pneumonia, central vascular catheter for bloodstream infection, urinary catheter for urinary tract infections. Necessary to distinguish device-associated infections. Y = Yes; N = No; UNK = Unknown.
BSI: Source of BSI | Required if the case definition code is BSI. Source/origin of the bloodstream infection. C = The same microorganism was cultured from the catheter or symptoms improve within 48 hours after removal of the catheter. Exception: Report microbiologically confirmed CVC-related BSI as CRI3-CVC if optional CRIs are included in the surveillance. C = Catheter, catheter type unknown; C-CVC = Central venous catheter; C-PVC = Peripheral venous catheter; C-ART = Arterial catheter; S = Secondary to another site, primary site unknown; S-PUL = Pulmonary infection; S-UTI = Urinary tract infection; S-SSI = Surgical site infection; S-DIG = Digestive tract infection; S-SST = Skin/Soft Tissue infection; S-OTH = Other infection or procedure; UO= None of the above, BSI of unknown origin; UNK=Unknown/Missing.
Microorganism * | Isolate result. Microorganism (MO) six letter code or negative code including reason why the isolate result is not available. _NA = Results not available; _NOEXA = Examination not done; _NONID = Microorganism not identified; _STERI = Sterile examination. See Code list in the HAI-Net ICU protocol Annexes 2 and 3 (see Related documents). It is recommended to use the extended microorganism list, even though minimal list codes are also allowed. Minimum one code per HAI is Required, the recommended maximum per HAI is 3 microorganisms.
AB | Antibiotic code. Antimicrobial drug for which susceptibility was tested, depends on the microorganism. In HWN, recommended antimicrobial codes are automatically generated.
SIR * | Final interpretation result of all different susceptibility tests performed. If antibiotic code is _NOTEST, SIR=NA. S = Susceptible; I = Intermediate; R = Resistant; UNK = Unknown; NA = Not applicable.
Patient outcome (relationship to HAI) | Relationship of HAI to ICU outcome in patients with HAI: • Discharged alive: patient was discharged alive; OR patient was still in the hospital and alive at end of follow-up during this hospital stay. • Death, HAI definitely contributed to death: use this category if a causal link between CDI and death can be demonstrated. • Death, HAI possibly contributed to death: use this category if no causal link between CDI and this case’s death can be demonstrated, but it is still plausible that CDI was at least a contributory factor. • Death, unrelated to HAI: use this category if the cause of death can be demonstrated not to be related to CDI. • Death, relationship to HAI unknown: use this category if no evidence of contributory factors to the cause of death is available. • Unknown: unknown patient outcome.
