# Creating a PPS point prevalence survey

There are two Point Prevalence Survey (PPS) options:

• Standard: Patient-based option allows advanced risk adjustment of healthcare-associated infection rates for inter-hospital comparisons. You enter all patient data for all patients, including those without HAI and/or antimicrobial use. Risk factors are collected for each patient (infected or not).

• Light: Unit-based option is less labour-intensive solution, produces partially the same indicators as Standard option for follow-up of trends, as well as the same descriptive results about infections and antimicrobial resistance, but with less possibility for risk-adjusted comparisons. You only enter patient data for patients with any antimicrobial use and/or a healthcare-associated infection. Consequently, in the Light protocol, each patient record must include details of at least one antimicrobial use or HAI.

Both options use the hospital data forms H1-H3, the ward data form W, and the national data form N.

However, the Standard option uses patient data form A, whereas the Light option uses numerator data form B.

Further details are provided in the HAI-Net PPS protocol (see Related documents).

PPS data collection is described in the following sections:

• Entering PPS hospital data

• Entering ward PPS data

• Entering PPS patient, antimicrobial use and HAI data
