Artificial Intelligence in Healthcare: An Innovative Solution for Infection Surveillance

Artificial Intelligence (AI) is carving a niche for itself in the healthcare industry. According to a recent study published in the American Journal of Infection Control (AJIC), AI technologies are robust tools that can accurately identify cases of healthcare-associated infections (HAIs), making them potentially invaluable additions to routine infection surveillance programs, even in intricate clinical scenarios. The study, conducted by researchers at Saint Louis University and the University of Louisville School of Medicine, drew attention to the necessity for unequivocal and regularized language when employing AI tools for infection surveillance.

The use of AI technology in this arena serves as an economical component of regular infection surveillance programs, particularly evident in settings with restricted resources. The incidence of HAIs, which are dangerous especially for critically ill hospitalized patients with devices like central lines, catheters, or even breathing tubes, have been abated by such programs and protocols, but the risk persists. Traditional HAI surveillance programs, while effective, do require significant resources, training, and expertise for maintenance. That’s where the attraction of AI as a cost-effective alternative becomes apparent–it augments existing surveillance programs, enhancing the care provided to high-risk patients.

The study assessed the efficacy of two AI tools: ChatGPT Plus by OpenAI and an open-source large language model Mixtral 8x7B. These tools were tested on two types of HAIs: central line-associated bloodstream infection (CLABSI) and catheter-associated urinary tract infection (CAUTI), and performed admirably when provided with clear prompts. However, the results underscored the importance of comprehensive information to ensure accurate results from these AI tools. Incomplete or ambiguous data could result in erroneous results, thereby necessitating vigilant human oversight.

The study points to a promising future where AI-powered tools might serve as a pocket-friendly way of amplifying surveillance programs and aiding infection preventionists in their everyday workflow. It represents a significant step towards integrating AI in the healthcare domain, specifically, in infection control. This collaborative vision of AI and human intelligence working together towards better and safer patient care is championed by APIC (Association for Professionals in Infection Control and Epidemiology).
