### HAI data

HAI data are entered through the Healthcare-associated infections (HAI) form. This form is opened by clicking the HAI button in the Patients | Risk factors General tab.

Figure 12: The Healthcare-associated infections (HAI) form

In the HAI form, a unique record is defined by the Case definition code. The same HAI case definition code cannot be reported twice in the same patient record, even with a different date of onset, because this is not possible according to the ECDC-PPS protocol. In fact, even the same infection site should not be allowed, but currently the programme looks only at the case definition codes. For example:

• A PN1 and a PN4 should not be reported in the same patient record although both definitions were met.

• Related codes for the same site should not be reported: e.g.,

o A PN1-5 should not be reported together with a NEO-PNEU (the latter has priority in neonates);

o A BSI should not be reported together with a NEO-CNSB or NEO-LCBI, and so on.

If data is incomplete, a Warning/Error message will open, listing required data items. Table 22 describes the variables in the HAI form. Further details are provided in the HAI-Net PPS protocol (see Related documents).

To specify healthcare-associated infection (HAI) data for a patient:

1. Click Patient/Antimicrobial use/HAI data in the main menu.

The Patients | Risk factors form opens displaying the General tab.

2. Scroll through the list of patients to locate the patient you are interested in and confirm that the patient details match the patient whose data you want to update.

3. Select Yes for the Patient has at least one HAI field to activate the HAI button.

4. Click HAI.

The Healthcare-associated infections (HAI) form (Figure 12) opens.

Note

• The date of onset of the HAI should be specified only if the HAI was not present at admission, that is, date of onset ≥ date of hospital admission

• The resistance markers (phenotypes) do not have labels depending on the micro-organism.

5. Optionally, click the User tab to view or edit the HAI user variables.

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

Descriptions of the variables in the HAI General tab are given in Table 22. Mandatory fields are indicated by a red asterisk *. Required fields are indicated by a black asterisk *.

Table 22: HAI General tab variables

Variable | Description
Header section | From ward PPS data (Table 19) and PPS patient risk data (Table 20).
Case definition code * | HAI case definition codes: specify subcategory, e.g. PN4 (see codebook), CVS-VASC. A single-case definition code should only be provided once per patient (no different infection episodes).
Relevant device * | To be specified for PN, BSI, NEO-LCBI, NEO-CNSB and UTI only. Relevant invasive device was in situ (even intermittently) for 48 hours (seven days for UTI) before onset of the infection, i.e. intubation for pneumonia, central/peripheral vascular catheter for bloodstream infections, urinary catheter for UTI; Unk=unknown. Yes/No/Unknown.
Origin of HAI * | Infection is associated with (1) current hospital; (2) another acute-care hospital; (3) other origin or unknown. Record ‘HAI present at admission’ if associated with an earlier stay in surveyed hospital or transferred from another facility.
HAI at admission * | Signs and symptoms of the infection were present at admission to the hospital; if not, provide date onset of infection. Yes/No/Unknown.
HAI associated to current ward | An HAI is associated with the current ward if the infection started on day 3 or later after admission to the current ward (where the date of admission to the ward is day 1) OR if the infection started on day 1 or 2 after a placement of an invasive device on the current ward OR if the patient was readmitted with an HAI present on admission associated to a previous stay in the same ward (within 30 days after operation for surgical site infections (or 90 days for deep and organ/space SSI after implant surgery), less than 28 days after discharge for C. difficile infections, less than 48 hours (two calendar days) after discharge for other HAIs).
Date of onset HAI | Date of onset of the infection (dd/mm/yyyy). Not to be recorded if signs/symptoms are present at admission, but mandatory if onset during current hospitalisation. Date of first signs or symptoms of the infection; if unknown, record date treatment was started for this infection or the date the first diagnostic sample was taken. If no treatment or sample, please estimate.
If BSI: source | If lab-confirmed bloodstream infection, specify the origin: catheter-related (central: C-CVC, peripheral C-PVC), secondary to another infection: pulmonary (S-PUL), urinary tract (S-UTI), digestive tract (S-DIG), surgical site infection (S-SSI), skin and soft tissue infection (S-SST), other infection (S-OTH), or BSI of (confirmed) unknown origin (UO); missing data, no information available=UNK; Secondary BSI reported as separate HAI, in addition to the primary infection if it matches the case definition.
