Hospital-acquired infections (HAIs) kill tens of thousands of Americans annually
Hospital-acquired infections (HAIs) are a significant cause for concern in the healthcare industry, particularly in the United States, where they claim tens of thousands of lives each year. According to the Centers for Disease Control and Prevention (CDC), Clostridium difficile or C. diff, a bacterium that causes hospital-acquired infections, sickens about 290,000 hospital patients annually and kills at least 27,000 people. This is just one type of HAI, and the overall impact of HAIs in the US is substantial.
Prior to the COVID-19 pandemic, it was estimated that HAIs affected approximately one in every thirty-one US healthcare patients, resulting in over 600,000 hospitalizations and 70,000 deaths annually. The pandemic has likely exacerbated the issue, as resources traditionally dedicated to infection prevention and control have been diverted to manage COVID-19. The full extent of the impact of the pandemic on HAI rates is yet to be determined.
The high prevalence of HAIs in the US has prompted the implementation of various preventative measures. These include improved hand hygiene, surface cleaning, touchpoint disinfection, and appropriate antibiotic use. According to the World Health Organization (WHO) and CDC, basic cleaning and infection prevention and control strategies can effectively combat the spread of infections. However, many hospitals struggle to control infections, and HAIs are spreading beyond healthcare facilities to places like nursing homes and patients' homes.
The overuse of antibiotics in hospitals is a significant contributor to the development of antibiotic-resistant "superbugs." According to the CDC, at least 30% of antibiotic prescriptions in hospitals are unnecessary or inappropriate, increasing patients' infection risk. This has led to concerns about the effectiveness of hospitals' infection prevention methods and calls for improved strategies to protect patient safety.
The impact of HAIs extends beyond the loss of life, also incurring substantial financial costs. The economic burden of HAIs in the US healthcare system is significant, with an estimated additional cost of $5 billion annually due to infections contracted in hospitals. This highlights the urgency of addressing HAIs and implementing effective prevention and control measures to reduce their occurrence and mitigate their impact on patient health and healthcare costs.

COVID-19 has impacted the disinfectant market and HAI prevention efforts
Hospital-acquired infections (HAIs) are a significant cause of patient harm and increased healthcare costs. The COVID-19 pandemic has impacted the disinfectant market and HAI prevention efforts in several ways.
Firstly, the pandemic has caused a surge in demand for disinfectant products, including wipes and sprays. In March 2020, sales of aerosol/spray disinfectants grew by over 340% compared to the previous year. The sale of multipurpose cleaners also spiked by more than 160% during the same period. This increased demand has been driven by the need to prevent the transmission of COVID-19 and other infectious diseases.
Secondly, the pandemic has disrupted supply chains and created fluctuations in the raw material costs for disinfectant manufacturers. This has presented challenges for the industry in meeting the soaring demand for disinfectant products.
Thirdly, the diversion of resources towards COVID-19 response efforts has impacted HAI prevention initiatives. A survey revealed that a significant portion of infection prevention professionals was dedicating most of their time to COVID-19 response. This diversion of resources may have compromised surveillance, data collection, and mitigation efforts for HAIs, potentially leading to an increase in infection rates.
Furthermore, the pandemic has led to changes in hospital practices, longer patient stays, and more frequent use of medical devices. These factors have likely contributed to an increased potential for device-associated infections. For instance, data from the CDC's National Healthcare Safety Network (NHSN) showed significantly higher incidences of central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), ventilator-associated events (VAEs), and methicillin-resistant Staphylococcus aureus (MRSA) bacteremia in 2021 compared to 2019.
The impact of COVID-19 on HAI prevention highlights the need for healthcare systems to develop innovative approaches to support and strengthen their infection prevention programs during public health emergencies.
