Implementing the Global-PPS on Antimicrobial Consumption and HAI in African Countries: Features and Advantages. Strengthening Capacity Building and Global Collaboration through a Harmonization Trajectory between WHO-PPS and Global-PPS
Abstract
Background
A Point Prevalence Survey (PPS) method is widely used to assess antimicrobial consumption and healthcare-associated infections in healthcare settings. Two major PPS initiatives, Global-PPS (2014) and WHO-PPS (2019) have developed parallel methodologies and tools, leading to confusion, hesitance and duplicated efforts in hospitals. To address this, the Global-PPS team and WHO began collaborating in 2024 to harmonize their methodologies and create a unified, interoperable PPS approach that can better support antimicrobial stewardship (AMS) efforts worldwide.
Methodology
Scientific and operational teams from Global-PPS and WHO-PPS held a series of online meetings to compare their systems' scope, goals, methodologies, and services. They identified common goals and key differences, and began outlining adjustments needed for harmonization. Through an iterative process, teams explored progressive steps toward creating an interoperable PPS system, allowing hospitals to participate in Global-PPS or WHO-PPS with a single dataset.
Results
When comparing Global-PPS and WHO-PPS data collection systems for inpatients, main differences were identified in the field of survey initiation and frequency, amount of detailed patient characteristics, antimicrobials studied, tools for data entry and validation, availability of feedback reporting and training, data ownership. Of note, an outpatient module is available for the Global-PPS only.
Discussion
Although some identified differences were important, they are considered manageable through adjustments to both data collection systems and the development of an interoperable IT infrastructure. Ultimately, harmonization would streamline processes such as data collection, entry, validation, feedback, and interpretation; enabling hospitals and countries to concentrate on implementing data-driven, context-specific AMS interventions.
