WHO launches first ever global report on infection prevention and control
The report reveals that good IPC programmes can reduce health care infections by 70 per cent, but warns that the coronavirus pandemic has exposed many challenges across all regions
The Covid-19 pandemic and other recent large disease outbreaks have highlighted the extent to which health care settings can contribute to the spread of infections, harming patients, health workers and visitors, if insufficient attention is paid to infection prevention and control (IPC). But a new report from the World Health Organization (WHO) shows that where good hand hygiene and other cost-effective practices are followed, 70 per cent of those infections can be prevented.
Today, out of every 100 patients in acute-care hospitals, seven patients in high-income countries and 15 patients in low- and middle-income countries will acquire at least one health care-associated infection (HAI) during their hospital stay. On average, one in every 10 affected patients will die from their HAI.
People in intensive care and newborns are particularly at risk. And the report reveals that approximately one in four hospital-treated sepsis cases and almost half of all cases of sepsis with organ dysfunction treated in adult intensive-care units are health care-associated.
“The Covid-19 pandemic has exposed many challenges and gaps in IPC in all regions and countries, including those which had the most advanced IPC programmes,” said Dr Tedros Adhanom Ghebreyesus, WHO Director General. “It has also provided an unprecedented opportunity to take stock of the situation and rapidly scale up outbreak readiness and response through IPC practices, as well as strengthening IPC programmes across the health system. Our challenge now is to ensure that all countries are able to allocate the human resources, supplies and infrastructures this requires.”
Amount of national IPC programmes has not improved
The new WHO report provides the first-ever global situation analysis of how IPC programmes are being implemented in countries around the world, including regional and country focuses. While highlighting the harm to patients and healthcare workers caused by HAIs and antimicrobial resistance, the report also addresses the impact and cost-effectiveness of infection prevention and control programmes and the strategies and resources available to countries to improve them.
In the last five years, WHO has conducted global surveys and country joint evaluations to assess the implementation status of national IPC programmes. Comparing data from the 2017-18 and the 2021-22 surveys, the percentage of countries having a national IPC programme did not improve; furthermore in 2021-22 only four out of 106 assessed countries (3.8 per cent) had all minimum requirements for IPC in place at the national level. This is reflected in inadequate implementation of IPC practices at the point of care, with only 15.2 per cent of health care facilities meeting all IPC minimum requirements, according to a WHO survey in 2019.
However, encouraging progress has been made in some areas, with a significant increase being seen in the percentage of countries having an appointed IPC focal point, a dedicated budget for IPC and curriculum for front-line health care workers’ training; developing national IPC guidelines and a national programme or plan for HAI surveillance; using multimodal strategies for IPC interventions; and establishing hand hygiene compliance as a key national indicator.
