The summer of 2024 heralds a renewed wave of infectious diseases such as mpox, measles, and meningitis, calling for drastic changes in infection prevention and control strategies in our healthcare system. Advanced expertise, improved airborne measures, and a transformation in assessing cost-effectiveness are indispensable to preempt future outbreaks and safeguard public health. With COVID-19 hospitalizations nearly doubling compared to the previous year and the airborne spread of the Mpox virus, the urgency to rethink our approach can’t be overstated.
The journal Medicine has cited five primary areas of concern requiring immediate attention. Firstly, there is the ‘siloed feedback loop’ issue where experts from the same industry who recommend and implement interventions form the governmental advisory panels responsible for justifying these strategies. This concern has been highlighted by labor unions, public health, and worker advocacy organizations, and has led to the addition of an Occupational Safety Professional to the Healthcare Infection Control Practices Advisory Committee (HICPAC). The ‘silo’ issue manifests itself in decisions like the implementation of enhanced barrier precautions in nursing homes, which have shown to potentially cripple community control of serious pathogens like Candida auris.
The second issue is that of overemphasizing the role of randomized controlled trials (RCTs). Public health interventions are often multifaceted and thus, the absence of supporting RCTs should not be an excuse for not firming up recommendations. Bias can significantly skew the interpretation of the results, which we can see in studies around chlorhexidine bathing and decolonization in nursing homes.
Thirdly, while hand hygiene is crucial, it should not be the only safety measure. A case in point is the Veterans Health Administration’s marked reduction in MRSA rates on the back of near-universal surveillance and isolation protocols.
The fourth challenge is ‘normalization of deviance’ or the acceptance of the status quo. The healthcare sector often finds itself focusing more on reacting to outbreaks and accepting long COVID impairments rather than preventing them. This not only compromises the sanctity of infection prevention work but also undermines public trust in health systems.
Lastly, there is the problem of assessing the cost-effectiveness of interventions through a narrow lens of profitability instead of public safety. Policymakers must reassess this myopic perception of cost-effectiveness and prioritize quality patient care over mere profit margins. We, therefore, need a comprehensive revamp in our strategies to provide safe indoor environments and curb the spread of airborne diseases. This will involve continuous monitoring of CO2 levels for optimal indoor ventilation, the use of HEPA filters, and the installation of UVC lighting fixtures. We need to promote a better understanding of bacterial microbiomes and establishing extensive screening methods for major community pathogens.
In this challenging yet rewarding field of infection prevention, we need to regain the trust of local governments and the public, aligning our outlooks with the long term goals of safety and quality care.
