The health of a community extends far beyond the walls of a hospital, and increasingly, medical researchers are recognizing the profound impact of non-medical factors on patient outcomes. Collectively known as social determinants of health (SDOH) – the conditions surrounding birth, growth, living, working, and aging – these forces are now understood to be critical drivers of infection rates and the effectiveness of infection control efforts.
These determinants aren’t simply about individual choices; they are deeply rooted in the distribution of money, power, and resources. Individuals lacking stable access to essential resources face heightened vulnerability to disease, including exposure to and infection by pathogens. This article explores the complex intersection of SDOH and infection control, and examines the evolving strategies health systems are employing to address this critical issue.
The factors influencing health outside of traditional medical care are multifaceted. Structural determinants encompass the physical environment, including access to stable housing, reliable transportation, accessible greenspace, safe pedestrian areas, and, crucially, healthy food options like grocery stores with fresh produce.
Beyond the physical environment, social determinants play a significant role, encompassing the strength of support systems, levels of community engagement, the presence of discrimination, and the degree of social integration. Education – including literacy, vocational training, language acquisition, and higher education opportunities – is also a key component.
Overall economic stability, encompassing employment opportunities, fair income scales, manageable cost of living, responsible debt management, and access to support agencies, exerts a huge influence. even access to health care itself – including provider availability, cultural competency, quality
The Link Between SDOH and Hospital-Acquired Infections
The connection between SDOH and hospital-acquired infections (HAIs) is becoming increasingly clear. Patients from disadvantaged backgrounds are more likely to present with underlying health conditions, weakened immune systems, and delayed access to preventative care, all of which increase their susceptibility to infection. Furthermore, rates of hospital-onset MRSA, partially attributable to higher rates of community-acquired MRSA. Critically, effective infection control and prevention programs require sufficient staffing and funding, resources often lacking in hospitals located in high-poverty urban and rural areas.
addressing SDOH: A Multi-Sector Approach
Mitigating the impact of SDOH requires a basic shift towards integrating health considerations into non-health sectors. As policymakers, city planners, and philanthropists address the challenges facing at-risk populations, health must be a central consideration, even when the primary focus appears unrelated.
Targeted efforts, such as increased funding for health facilities in high-poverty areas, are also essential. While the current administration’s “Make America Healthy Again” initiatives have seen cuts to social determinants of health research at the Centers for disease Control (CDC), funding for community-based and rural health clinics remains. The CDC’s work focuses on understanding how factors like housing stability, income, education, transportation, and neighborhood conditions shape health outcomes.
One senior official stated that eliminating this research doesn’t eliminate health disparities, but rather diminishes the ability to measure them, anticipate risks, and target prevention efforts effectively. Without understanding these upstream drivers, public health responses become reactive and costly, pushing preventable problems deeper into the healthcare system.
Immediate Impact: Biocidal Materials and Hospital Environments
While broader societal changes addressing health equity and SDOH are crucial, the built environment within hospitals can offer an immediate impact on HAI rates.Investing in biocidal materials, such as copper-infused EOScu – currently the only affordable option – can reduce the pathogen load surrounding patients without increasing the workload for nurses, infection preventionists, or environmental services staff. This practical, one-time investment can serve as a vital bridge to a future where SDOH no longer exert such a significant influence on patient outcomes.
