Health equity is the state in which everyone has a fair and just opportunity to attain their highest level of health.

Health inequities occur when unfair processes in the distribution of resources affecting health disproportionately prevent the attainment of that highest level of health in specific populations.
Reference Braveman and Gruskin2,Reference People3
Health inequities are pervasive and lead to differential patient outcomes for a variety of disease states, ranging from chronic diseases like Type 2 diabetes mellitus and hypertension to infections like coronavirus disease-2019 (COVID-19).

Thus, opportunities exist for education and awareness about health equity and how it applies to infectious diseases, healthcare epidemiology, and antimicrobial stewardship. To underscore the importance of preparing the healthcare workforce to understand, recognize, and respond to health inequities, Uehling et al
Reference Uehling, Hall-Clifford, Kinnard and Wimberly18
asked >200 hospital employees to describe their understanding of health equity as a concept, and perceptions of equity initiatives implemented in their hospital. In the results of their survey, published in 2023, <25% of respondents could correctly define either health equity or equity at a broader level.
Reference Uehling, Hall-Clifford, Kinnard and Wimberly18
Understanding definitions of health equity terminology can be an important first step toward identifying and differentiating health disparities and inequities occurring in our field (Table 1). However, clinicians and researchers need to move beyond mere documentation toward identification, investigation, and mitigation of these upstream drivers leading to the observed disparities. The purposes of this commentary are (1) to provide context for why health equity is important in healthcare epidemiology, infection prevention, and antimicrobial stewardship and (2) to share action steps for individuals, institutions, and health systems.

How social determinants of health (SDOH) interact to cause and exacerbate disparities within infectious diseases
Social determinants of health (SDOH) are defined as the nonmedical factors that influence health outcomes including (but not limited to) education quality, economic stability, neighborhood, housing environment, and healthcare access.
Reference Brown and Homan19
Many disparities observed in clinical outcomes among patients from minoritized backgrounds are likely driven by inequities in these factors, as well as additional systems of oppression that may themselves be considered separate SDOH (ie, racism, homophobia, ableism, sexism, and ageism).
Reference Marcelin, Swartz and Bernice20
These factors can influence patient outcomes from infectious diseases.
For example, differences in access to quality educational opportunities can contribute to lower levels of literacy, which can severely affect the degree to which individuals can find, understand, and use information to inform their health-specific literacy or health-related decision making.
Reference Hickey, Masterson Creber and Reading21–Reference Prince, Schmidtke, Beck and Hadden23
More than 80 million American adults have low health literacy, with disproportionately higher representation among older adults and people from racially and ethnically minoritized backgrounds.
Reference Prince, Schmidtke, Beck and Hadden23
Historical racial residential segregation has played a significant role in these inequities due to artificial limitations on quality educational access and in some cases, poorly funded education systems. Moreover, the specter of racism in healthcare with historical and contemporaneous medical mistreatment has resulted in justified healthcare mistrust across communities of racially and ethnically minoritized backgrounds. Several examples are well-known, such as the US Public Health Service–funded study of untreated syphilis in Black men at the Tuskegee Institute, the unauthorized retrieval and profits from the use of Mrs. Henrietta Lacks’ cervical cells without her consent, and the compulsory sterilization of Native American women at Indian Health Services hospitals.
Reference Marcelin, Swartz and Bernice20,Reference Scharff, Mathews, Jackson, Hoffsuemmer, Martin and Edwards24,Reference Lawrence25
This mistrust can interfere with health literacy development because it can influence interactions with access to healthcare-related resources and overall health decision making.
Reference Elam-Evans, Jones and Vashist26,Reference Felton, Rabinowitz and Strickland27
For example, during the COVID-19 pandemic, people from racially and ethnically minoritized backgrounds were disproportionately represented in rates of disease, hospitalization, and death from SARS-CoV-2, yet, once vaccines were available, these groups were the least represented among persons who received the COVID-19 vaccine.
Reference Kriss, Hung and Srivastav28–Reference Rossen, Ahmad and Anderson30
Higher reliance on social media as a source of COVID-19 education was noted among people from racially and ethnically minoritized groups, and widespread misinformation and disinformation campaigns on these platforms may have resulted in compromised health literacy, adversely impacting healthcare decision making.
Reference Goldsmith, Rowland-Pomp and Hanson31
Furthermore, inadequate options to appropriately communicate with individuals with limited English proficiency also compromise health literacy and negatively influence outcomes for those patient populations. Individuals with limited English proficiency experience barriers to accessing healthcare coverage, which may delay treatment seeking and the receipt of appropriate care.
Reference Foiles Sifuentes, Robledo Cornejo, Li, Castaneda-Avila, Tjia and Lapane32
These inequities likely have major downstream effects, including longer emergency room visits and hospital admissions in pediatric and adult patients who speak a language other than English.
Reference Goldman, Amin and Macpherson33,Reference Karliner, Kim, Meltzer and Auerbach34
Differences in infection prevalence, due to language barriers, have also been observed among pediatric populations. Higher rates of central-line–related bloodstream infections (CLABSIs) have been documented in pediatric patients with limited English proficiency.
Reference McGrath, Bettinger and Stimpson35
Reducing the negative impacts of language barriers in infection prevention and antimicrobial stewardship is essential for HAI prevention, especially given the importance of patient education (eg, preoperative chlorhexidine bathing or wound care and antibiotic education at patient discharge).
Reference Prochaska, Caballero, Fabre and Milstone12
Biases in hiring policies and practices as well as inequities in access to quality education and lower rates of advanced education result in a disproportionately high representation of individuals from minoritized backgrounds in low-wage employment. These biases likely contribute to the disproportionate high levels of social and economic vulnerability, including low socioeconomic status (SES) observed across groups from minoritized backgrounds, compared with individuals from privileged backgrounds less harmed by racism.
Reference Weller36
Because employment guides monetary income, and income is required for housing, higher proportions of people from racially and ethnically minoritized backgrounds reportedly live in multigenerational or overcrowded housing, which may facilitate infection transmission through close contact.
Reference Marcelin, Swartz and Bernice20
This situation was highlighted during the COVID-19 pandemic. People from racially or ethnically minoritized backgrounds were more likely to work in lower-income healthcare personnel roles (eg, certified nursing assistants and medical assistants) and were at higher risk of contracting COVID-19 due to presumed increased exposures in either or both work and nonwork settings.
Reference Zlotorzynska, Chea and Eure16
Low SES can influence access to healthcare, which further exacerbates disparities in infectious diseases. For example, disproportionate rates of Clostridium difficile infection (CDI) have been frequently reported in individuals who reside in areas of low SES when compared to those who live in areas of higher SES.
Reference Argamany, Delgado and Reveles37–Reference Skrobarcek, Mu and Ahern39
People who are uninsured or underinsured may experience challenges that hinder their ability to receive care for the management of chronic illnesses, which may subsequently increase their risk of infectious complications.
Reference Mao, Kelly and Machan40
Patients from racially and ethnically minoritized backgrounds who were diagnosed with CDI at a hospital serving primarily low SES communities were more likely to be under- or uninsured.
Reference Lee, Zhou, Ortiz-Gratacos, Al Isso, Tan and Abdul-Mutakabbir8
They were also more likely to have been diagnosed with diabetes and chronic kidney disease (CKD), and a pre-existing CKD diagnosis contributed to the increased odds of severe CDI seen in minoritized patients.
Reference Lee, Zhou, Ortiz-Gratacos, Al Isso, Tan and Abdul-Mutakabbir8
This gap will likely continue to widen as areas of low SES are less likely to have an adequate number of healthcare resources and/or professionals to provide necessary services.
Challenges with identifying and mitigating health inequities in infection prevention and antimicrobial stewardship
Several challenges exist in identifying and mitigating health inequities in infection prevention and antimicrobial stewardship. These can be broadly grouped into themes including (1) diversity of the healthcare workforce and patient access to clinicians, where many minoritized communities are underrepresented, and (2) challenges with availability and quality of data, affecting patient care and community health outcomes.
Challenges with healthcare workforce diversity and access
Patient–clinician cultural concordance can promote positive clinical outcomes, demonstrating that a diverse healthcare epidemiology, infection prevention, and antimicrobial stewardship workforce is essential to mitigate health inequities and serve diverse populations.
Reference Shen, Peterson and Costas-Muñiz41
Black, Hispanic/Latino, American Indian/Alaska Native, and Native Hawaiian/Pacific Islander individuals are underrepresented as trainees and practicing physicians in the United States relative to their census demographics.
Reference Cichon, Green, Hilker and Inclusion42–Reference Rogo, Holland and Fassiotto45
Furthermore, individuals with these minoritized racial and ethnic identities are underrepresented in leadership positions,
Reference Marcelin, Manne-Goehler and Silver44

Reference Marcelin, Khazanchi and Lyden46,Reference Wiley, Kalu and Lyden47

Reference Marcelin, Bares and Fadul48
and promotion.
Reference Manne-Goehler, Krakower, Marcelin, Salles, Del Rio and Stead50–Reference Stead, Manne-Goehler and Blackshear52
Many of these gaps reported for physicians undoubtedly exist for other healthcare team members such as pharmacists, infection preventionists, advanced practice clinicians, etc; however, data from these professional groups are sparse.
Reference Abdul-Mutakabbir, Arya and Butler53–Reference Bissell, Johnston and Smith56
Furthermore, there is a dearth of data describing the contribution and impacts of infectious disease healthcare workers from lesbian, gay, bisexual, transgender, queer and nonbinary gender (LGBTQ+) communities or healthcare workers with disabilities. To address these gaps, medical societies can commit to identifying and mitigating these workforce inequities through coordinated strategies,
Reference Marcelin, Khazanchi and Lyden46,Reference Wiley, Kalu and Lyden47
ranging from intentional recruitment to retention and recognition. Concurrent with existing efforts to inspire interest in infectious diseases (ID), pathway programs (starting as early as elementary school) can expose young learners to ID careers, and their development and execution should be intentional to ensure that individuals from backgrounds historically excluded have access to these career opportunities.
Reference Rogo, Holland and Fassiotto57
Ensuring an adequate workforce serving rural and community hospitals is also necessary. Patients in smaller community hospitals, particularly in the Southeastern United States, were disproportionately affected by CDI, catheter-associated urinary tract infections (CAUTIs), and CLABSIs during the height of the COVID-19 pandemic.
Reference Advani, Sickbert-Bennett and Moehring58
Children living in rural counties (compared to children living in urban counties) have increased rates of inappropriate antibiotic use.
Reference Dantuluri, Bruce and Edwards59
To address these geographic differences in HAIs and antibiotic prescribing quality, improving access to ID expertise (local or telehealth) is warranted to serve smaller rural community hospitals.
Reference Livorsi, Abdel-Massih and Crnich60
Academic healthcare facilities are often overrepresented in research, limiting the generalization of published data, with inadvertent exclusion of rural populations. In a survey assessing collection of SDOH data as a routine part of HAI surveillance in US-based hospitals, 7 (27%) of 26 responding facilities represented community hospitals and only 4 (16%) included public and federal hospitals.
Reference McGrath, Logan and Deloney10
Furthermore, of the responding facilities, only 1 (4%) of 26 responding facilities were from Western states (11 were from Southern states), which likely influenced the inclusion of indigenous persons living in Western states in these studies. Only 8 (30%) of 27 facilities collected SDOH patient variables and, of these 8 facilities, 7 (88%) were academic centers.
Reference McGrath, Logan and Deloney10
More than 70% of US hospitals have <200 beds, and many of these facilities serve communities in need and those from minoritized communities.

Inclusive cultures must be developed and fostered during health professions training and patient care,
Reference Flores, Tan and Bryant43,Reference Rogo, Holland and Fassiotto45,Reference Essien, Agbafe and Norris62
as well as through intentional assembly of healthcare epidemiology–infection prevention–antimicrobial stewardship teams to include intersectional identities. Unconscious or implicit bias describes “associations or attitudes that reflexively alter our perceptions, thereby affecting behavior, interactions, and decision making,”
Reference Marcelin, Siraj, Victor, Kotadia and Maldonado63
and can contribute to inequities in antimicrobial stewardship. In one study, female antimicrobial stewardship pharmacists were less likely to have their antibiotic recommendations accepted by prescribing clinicians than male antimicrobial stewardship pharmacists.
Reference Vaughn, Giesler and Mashrah14
Approaches to counter unconscious bias are multidimensional; however, at the core they operate in conjunction with methods to increase diversity, equity, and inclusion, which includes diversifying the healthcare workforce.
Reference Marcelin, Manne-Goehler and Silver44,Reference Marcelin, Siraj, Victor, Kotadia and Maldonado63
The case for supporting equity, diversity, inclusion, and access in the antimicrobial stewardship and infection prevention workforce is multifaceted. In addition to greater opportunity for clinician–patient concordant relationships, some data have demonstrated that diverse teams function better and are more successful in research.
Reference Miller and Del Carmen Triana64
Diverse teams produced more innovative research and published in higher-impact journals, which may allow for an increase in the dissemination of the innovative findings.
Reference Yang, Tian, Woodruff, Jones and Uzzi65
Importantly, addressing healthcare workforce inequities contributes directly to improved patient care.
Reference Snyder, Upton, Hassett, Lee, Nouri and Dill66
Challenges with availability and quality of data
Medical research typically captures demographic information on sex, age, race, and ethnicity, but addressing inequities is rarely the objective, which prompted a call to expand the literature evaluating inequities in HAI incidence.
Reference Kim, Kabbani and Dube17,Reference Chen, Khazanchi, Bearman and Marcelin67,Reference Evans and Wiley68
In a scoping review of health-equity antibiotic prescribing studies, only 23% of studies reported a specific equity objective, whereas 48% of the included studies reported patient or prescriber characteristics.
Reference Kim, Kabbani and Dube17
Among studies reporting any health equity markers, people from racial and ethnic minoritized groups were less likely to receive antibiotics overall
Reference Wattles, Jawad and Feygin15,Reference Gerber, Prasad and Localio69
or were less likely to receive firstline antibiotic treatment.
Reference Wurcel, Essien and Ortiz70
Further disparities were observed based on geographic location, with higher antibiotic prescribing in southern regions
Reference Goodman, Baghdadi and Magder71
and rural areas.
Reference Dantuluri, Bruce and Edwards59
Additionally, socioeconomic status also influenced equitable prescribing; privately insured people were more likely to receive antibiotics compared with the uninsured.
Reference Hersh, Shapiro, Pavia and Shah72
Despite these disparities, research regarding potential drivers (or upstream causes) of observed disparities is lacking.
Reference Kim, Kabbani and Dube17
Recent studies have evaluated disparities related to multidrug resistance, infection prevention efforts and outbreak response, HAIs, and specific conditions, including candidemia, CDI, and COVID-19.
Reference Brown, Henderson, Ruegsegger, Moody and van Duin4–Reference Lee, Zhou, Ortiz-Gratacos, Al Isso, Tan and Abdul-Mutakabbir8,Reference Prochaska, Caballero, Fabre and Milstone12,Reference Schrodt, Hart, Calanan, McLees, Perz and Perkins13,Reference Zlotorzynska, Chea and Eure16,Reference McGrath, Bettinger and Stimpson35,Reference O’Halloran, Holstein and Cummings73
Data regarding health inequities in inpatient antibiotic prescribing are very limited. Kim et al
Reference Kim, Kabbani and Dube17
reported that 55 (90%) of 61 articles in their scoping review described outpatient settings and only 1 (1.6%) was from the acute-care setting. Their review also noted very few stewardship intervention studies, only 4 (6.6%) of 61 studies.
Reference Kim, Kabbani and Dube17
Considering that patients who are uninsured and underinsured often do not have access to outpatient clinics and may use the emergency department or hospital as their only form of healthcare, the lack of published data in the inpatient setting is a significant limitation in the consideration of health inequities in antibiotic prescribing.
As researchers evaluate these disparities, even within what many consider to be basic demographic variables, they must be aware of how they are collecting the information and what methodologic biases may be introduced. For example, age is quantifiable, but age stratification (eg, who are considered “older adults”) and how disparities in infection incidence and antimicrobial use affect various age categories are all important considerations for researchers. Accurate identification of sex, race, and ethnicity is also key for both clinicians and researchers. Gender identity and biological sex are different constructs, and knowledge of both are necessary not only to provide high-level medical care but also to perform quality research, especially when disparities might exist among different groups.
74
Clinicians and researchers also tend to make assumptions about race and ethnicity that may not align with their patients’ and study participants’ self-identified race and ethnicity, especially when these characteristics are limited to finite categories.
Reference Agawu, Chaiyachati, Radack, Duncan and Ellison75
Such assumptions can affect the care these patients receive if clinicians’ implicit racial biases translate into decision making either consciously or subconsciously and can in turn affect study analyses on racial disparities in infectious diseases. Race and ethnicity are sociopolitical, not biological constructs; therefore, they should not be used in clinical practice to make inferences about physiologic function. Care should be taken in research to understand structural barriers causing racialized disparities rather than assigning race itself as a risk factor.
Reference Cerdeña, Plaisime and Tsai76–Reference Boyd, Lindo, Weeks and McLemore79
Finally, some SDOH variables are often not collected or are overlooked in medical research, such as disability status and housing or food insecurity. The charge to incorporate such variables into medical research extends beyond the individual clinician and researcher. Regulatory and government agencies should consider these when determining standard metrics for reportable infectious diseases and conditions. The National Healthcare Safety Network (NHSN) captures HAI and antimicrobial use data from acute and postacute care facilities.
80
HAI case reporters can include race and ethnicity data, but the field is optional. The antimicrobial use module captures only aggregate facility-level or unit-level information. Although this information may be helpful to assess facility-level interventions, analysis of disparities in care or prescribing based on age, gender, race, or ethnicity cannot be performed.
Next steps and call to action
Prioritizing elimination of healthcare disparities requires individual, institutional, and public health level interventions. Here, we provide actionable recommendations for mitigating the equity gaps at each level (Fig. 1).
Figure 1. Actions for individuals, institutions, and public health organizations to mitigate impacts of health inequities.
Individuals
A starting point for clinicians is an urgent commitment to creating a culture of equity and inclusion in healthcare spaces (Fig. 1). To create environments that provide patients and staff with what they need to succeed through a lens of equity, thorough assessments of individual practices should be conducted to determine areas of greatest need. For example, Fortin-Leung et al
Reference Fortin-Leung and Wiley81
raised questions about the paucity of race and ethnicity data built into antimicrobial stewardship programs. Acknowledging that patient-level characteristics from birth to death can affect antimicrobial prescribing, use, and administration, they suggested that prescribers could seek to understand how cultural differences along racial, ethnic or gender lines affect nonprescription antibiotic use, medication adherence, and drive differences in prescribing behavior.
Because SDOH may have varying impacts on patient health, healthcare personnel should intentionally seek out education on the impact of SDOH and SES on patient health.
Reference Brown, Henderson, Ruegsegger, Moody and van Duin4
Healthcare professionals remain the most trusted sources of health information in our current era of declining health literacy and access to high-quality health information. Staying appropriately informed can help clinicians maintain this trust and properly advocate for patients. Patient advocacy may be strengthened by recruiting and retaining a diverse workforce. Through mentorship and sponsorship for people from different backgrounds, healthcare personnel can prioritize support for successful career advancement.
Organizational
Healthcare systems and facility leadership are responsible for creating a culture of equity in their institutions.
82
Steps to be taken at institutions include the following: (1) assessing whether care delivery is equitable; (2) prioritizing quality improvement interventions that address differential care delivery; (3) providing high-quality health equity and implicit bias training for healthcare professionals; (4) leveraging data for individual-level clinician feedback on health equity measures; and (5) making public statements of goals and actions to improve equity, in addition to internal commitments (Fig. 1). For example, during the COVID-19 pandemic, infectious disease, and antimicrobial stewardship leadership at one hospital recognized that access to monoclonal antibody infusion for COVID-19 management was inequitable. They leveraged an emergency department fast-track location and existing staff to make the treatment available for an underserved community.
Reference Mena Lora, Echeverria and Lindsey11
Sustainable measures to mitigate disparities require accountability. Public and private institutions, including societies dedicated to healthcare epidemiology and antibiotic stewardship, have made public declarations of diversity equity and inclusion commitments.
83,84
Yet, without high-quality data collection and publicized data reviews, accountability may not be feasible for health systems.
Reference McGrath, Logan and Deloney10
Additionally, the validity of SDOH, race, and ethnicity data entered into the electronic health record (EHR) have often been called into question, creating challenges for collecting and interpreting HAI inequity data.
Reference Agawu, Chaiyachati, Radack, Duncan and Ellison75
However, interventions to correct these patterns might have limited impact in the absence of data validity tools for EHR systems to capture accurate data points. Despite these challenges, healthcare institutions can still develop anchor missions focused on addressing inequities for their local communities. For example, a Chicago-based health system crafted a multipronged framework that named racism and poverty as targeted causes of inequities. They embarked on a health equity mission to invest locally, collaborated with their surrounding community across all care spectrums, and they developed performance improvement plans to improve their patient outcomes.
Reference Ansell, Oliver-Hightower, Goodman, Lateef and Johnson85
The level of commitment to equity may not be replicable for every institution, but we recommend that institutions identify and tackle a singular equity mission that is achievable and feasible within an established timeline. Healthcare system and facility leadership should be purposeful in recruiting a diverse and skilled workforce in healthcare epidemiology, infection prevention, and antimicrobial stewardship. Institutions can frequently conduct equity reviews and proactively correct identified deficiencies.
Public health systems
Public health engagement at the federal, state, and local levels is needed to address health inequities (Fig. 1). National, state, and community policies, structural inequities, and differential access to reliable information sources are important factors. The COVID-19 pandemic revealed the need for future public health initiatives to address systematic inequalities that can perpetuate and lead to differences in population and individual outcomes.
Reference Li, Cai, Mao, Cheng and Temkin-Greener9
Action steps for public health include the following: (1) requiring surveillance and research activities that include health equity objectives and capture the needed data to support decision making and implementation science to address inequities; (2) providing necessary analytic resources to help characterize health inequities at the national, community, healthcare system, and facility levels to provide a compass for where action is needed; (3) communicating health information effectively to a variety of different audiences and health literacy levels; (4) facilitating access to subject matter expertise in healthcare epidemiology, infection prevention, antibiotic stewardship in health departments across the country; and (5) incorporating a health equity lens into guidance and policies for healthcare epidemiology, infection prevention, and antibiotic stewardship implementation. Regulatory and accreditation partners, such as The Joint Commission, can facilitate policy change. For example, in 2023 new health equity standards were released by The Joint Commission to establish a new baseline of equitable delivery of healthcare.
86
In conclusion, inequities in healthcare occur at every resource level. Steps to advance health equity should be considered at every level, whether a well-resourced health system or a rural critical-access hospital. Advancing health equity includes delivery of safe and equitable patient care and recruiting individuals with diverse backgrounds to healthcare epidemiology, infection prevention, and antimicrobial stewardship career paths.

Many of these gaps reported for physicians undoubtedly exist for other healthcare team members such as pharmacists, infection preventionists, advanced practice clinicians, etc; however, data from these professional groups are sparse. Reference Abdul-Mutakabbir, Arya and Butler53–Reference Bissell, Johnston and Smith56 Furthermore, there is a dearth of data describing the contribution and impacts of infectious disease healthcare workers from lesbian, gay, bisexual, transgender, queer and nonbinary gender (LGBTQ+) communities or healthcare workers with disabilities. To address these gaps, medical societies can commit to identifying and mitigating these workforce inequities through coordinated strategies, Reference Marcelin, Khazanchi and Lyden46,Reference Wiley, Kalu and Lyden47 ranging from intentional recruitment to retention and recognition. Concurrent with existing efforts to inspire interest in infectious diseases (ID), pathway programs (starting as early as elementary school) can expose young learners to ID careers, and their development and execution should be intentional to ensure that individuals from backgrounds historically excluded have access to these career opportunities. Reference Rogo, Holland and Fassiotto57
Ensuring an adequate workforce serving rural and community hospitals is also necessary. Patients in smaller community hospitals, particularly in the Southeastern United States, were disproportionately affected by CDI, catheter-associated urinary tract infections (CAUTIs), and CLABSIs during the height of the COVID-19 pandemic. Reference Advani, Sickbert-Bennett and Moehring58 Children living in rural counties (compared to children living in urban counties) have increased rates of inappropriate antibiotic use. Reference Dantuluri, Bruce and Edwards59 To address these geographic differences in HAIs and antibiotic prescribing quality, improving access to ID expertise (local or telehealth) is warranted to serve smaller rural community hospitals. Reference Livorsi, Abdel-Massih and Crnich60 Academic healthcare facilities are often overrepresented in research, limiting the generalization of published data, with inadvertent exclusion of rural populations. In a survey assessing collection of SDOH data as a routine part of HAI surveillance in US-based hospitals, 7 (27%) of 26 responding facilities represented community hospitals and only 4 (16%) included public and federal hospitals. Reference McGrath, Logan and Deloney10 Furthermore, of the responding facilities, only 1 (4%) of 26 responding facilities were from Western states (11 were from Southern states), which likely influenced the inclusion of indigenous persons living in Western states in these studies. Only 8 (30%) of 27 facilities collected SDOH patient variables and, of these 8 facilities, 7 (88%) were academic centers. Reference McGrath, Logan and Deloney10 More than 70% of US hospitals have <200 beds, and many of these facilities serve communities in need and those from minoritized communities. Reference Mena Lora, Echeverria and Lindsey11,Reference Stenehjem, Hyun and Septimus61
Inclusive cultures must be developed and fostered during health professions training and patient care, Reference Flores, Tan and Bryant43,Reference Rogo, Holland and Fassiotto45,Reference Essien, Agbafe and Norris62 as well as through intentional assembly of healthcare epidemiology–infection prevention–antimicrobial stewardship teams to include intersectional identities. Unconscious or implicit bias describes “associations or attitudes that reflexively alter our perceptions, thereby affecting behavior, interactions, and decision making,” Reference Marcelin, Siraj, Victor, Kotadia and Maldonado63 and can contribute to inequities in antimicrobial stewardship. In one study, female antimicrobial stewardship pharmacists were less likely to have their antibiotic recommendations accepted by prescribing clinicians than male antimicrobial stewardship pharmacists. Reference Vaughn, Giesler and Mashrah14 Approaches to counter unconscious bias are multidimensional; however, at the core they operate in conjunction with methods to increase diversity, equity, and inclusion, which includes diversifying the healthcare workforce. Reference Marcelin, Manne-Goehler and Silver44,Reference Marcelin, Siraj, Victor, Kotadia and Maldonado63
The case for supporting equity, diversity, inclusion, and access in the antimicrobial stewardship and infection prevention workforce is multifaceted. In addition to greater opportunity for clinician–patient concordant relationships, some data have demonstrated that diverse teams function better and are more successful in research. Reference Miller and Del Carmen Triana64 Diverse teams produced more innovative research and published in higher-impact journals, which may allow for an increase in the dissemination of the innovative findings. Reference Yang, Tian, Woodruff, Jones and Uzzi65 Importantly, addressing healthcare workforce inequities contributes directly to improved patient care. Reference Snyder, Upton, Hassett, Lee, Nouri and Dill66
Challenges with availability and quality of data
Medical research typically captures demographic information on sex, age, race, and ethnicity, but addressing inequities is rarely the objective, which prompted a call to expand the literature evaluating inequities in HAI incidence. Reference Kim, Kabbani and Dube17,Reference Chen, Khazanchi, Bearman and Marcelin67,Reference Evans and Wiley68 In a scoping review of health-equity antibiotic prescribing studies, only 23% of studies reported a specific equity objective, whereas 48% of the included studies reported patient or prescriber characteristics. Reference Kim, Kabbani and Dube17 Among studies reporting any health equity markers, people from racial and ethnic minoritized groups were less likely to receive antibiotics overall Reference Wattles, Jawad and Feygin15,Reference Gerber, Prasad and Localio69 or were less likely to receive firstline antibiotic treatment. Reference Wurcel, Essien and Ortiz70 Further disparities were observed based on geographic location, with higher antibiotic prescribing in southern regions Reference Goodman, Baghdadi and Magder71 and rural areas. Reference Dantuluri, Bruce and Edwards59 Additionally, socioeconomic status also influenced equitable prescribing; privately insured people were more likely to receive antibiotics compared with the uninsured. Reference Hersh, Shapiro, Pavia and Shah72 Despite these disparities, research regarding potential drivers (or upstream causes) of observed disparities is lacking. Reference Kim, Kabbani and Dube17
Recent studies have evaluated disparities related to multidrug resistance, infection prevention efforts and outbreak response, HAIs, and specific conditions, including candidemia, CDI, and COVID-19. Reference Brown, Henderson, Ruegsegger, Moody and van Duin4–Reference Lee, Zhou, Ortiz-Gratacos, Al Isso, Tan and Abdul-Mutakabbir8,Reference Prochaska, Caballero, Fabre and Milstone12,Reference Schrodt, Hart, Calanan, McLees, Perz and Perkins13,Reference Zlotorzynska, Chea and Eure16,Reference McGrath, Bettinger and Stimpson35,Reference O’Halloran, Holstein and Cummings73 Data regarding health inequities in inpatient antibiotic prescribing are very limited. Kim et al Reference Kim, Kabbani and Dube17 reported that 55 (90%) of 61 articles in their scoping review described outpatient settings and only 1 (1.6%) was from the acute-care setting. Their review also noted very few stewardship intervention studies, only 4 (6.6%) of 61 studies. Reference Kim, Kabbani and Dube17 Considering that patients who are uninsured and underinsured often do not have access to outpatient clinics and may use the emergency department or hospital as their only form of healthcare, the lack of published data in the inpatient setting is a significant limitation in the consideration of health inequities in antibiotic prescribing.
As researchers evaluate these disparities, even within what many consider to be basic demographic variables, they must be aware of how they are collecting the information and what methodologic biases may be introduced. For example, age is quantifiable, but age stratification (eg, who are considered “older adults”) and how disparities in infection incidence and antimicrobial use affect various age categories are all important considerations for researchers. Accurate identification of sex, race, and ethnicity is also key for both clinicians and researchers. Gender identity and biological sex are different constructs, and knowledge of both are necessary not only to provide high-level medical care but also to perform quality research, especially when disparities might exist among different groups. 74 Clinicians and researchers also tend to make assumptions about race and ethnicity that may not align with their patients’ and study participants’ self-identified race and ethnicity, especially when these characteristics are limited to finite categories. Reference Agawu, Chaiyachati, Radack, Duncan and Ellison75 Such assumptions can affect the care these patients receive if clinicians’ implicit racial biases translate into decision making either consciously or subconsciously and can in turn affect study analyses on racial disparities in infectious diseases. Race and ethnicity are sociopolitical, not biological constructs; therefore, they should not be used in clinical practice to make inferences about physiologic function. Care should be taken in research to understand structural barriers causing racialized disparities rather than assigning race itself as a risk factor. Reference Cerdeña, Plaisime and Tsai76–Reference Boyd, Lindo, Weeks and McLemore79
Finally, some SDOH variables are often not collected or are overlooked in medical research, such as disability status and housing or food insecurity. The charge to incorporate such variables into medical research extends beyond the individual clinician and researcher. Regulatory and government agencies should consider these when determining standard metrics for reportable infectious diseases and conditions. The National Healthcare Safety Network (NHSN) captures HAI and antimicrobial use data from acute and postacute care facilities. 80 HAI case reporters can include race and ethnicity data, but the field is optional. The antimicrobial use module captures only aggregate facility-level or unit-level information. Although this information may be helpful to assess facility-level interventions, analysis of disparities in care or prescribing based on age, gender, race, or ethnicity cannot be performed.
Next steps and call to action
Prioritizing elimination of healthcare disparities requires individual, institutional, and public health level interventions. Here, we provide actionable recommendations for mitigating the equity gaps at each level (Fig. 1).
Figure 1. Actions for individuals, institutions, and public health organizations to mitigate impacts of health inequities.
Individuals
A starting point for clinicians is an urgent commitment to creating a culture of equity and inclusion in healthcare spaces (Fig. 1). To create environments that provide patients and staff with what they need to succeed through a lens of equity, thorough assessments of individual practices should be conducted to determine areas of greatest need. For example, Fortin-Leung et al Reference Fortin-Leung and Wiley81 raised questions about the paucity of race and ethnicity data built into antimicrobial stewardship programs. Acknowledging that patient-level characteristics from birth to death can affect antimicrobial prescribing, use, and administration, they suggested that prescribers could seek to understand how cultural differences along racial, ethnic or gender lines affect nonprescription antibiotic use, medication adherence, and drive differences in prescribing behavior.
Because SDOH may have varying impacts on patient health, healthcare personnel should intentionally seek out education on the impact of SDOH and SES on patient health. Reference Brown, Henderson, Ruegsegger, Moody and van Duin4 Healthcare professionals remain the most trusted sources of health information in our current era of declining health literacy and access to high-quality health information. Staying appropriately informed can help clinicians maintain this trust and properly advocate for patients. Patient advocacy may be strengthened by recruiting and retaining a diverse workforce. Through mentorship and sponsorship for people from different backgrounds, healthcare personnel can prioritize support for successful career advancement.
Organizational
Healthcare systems and facility leadership are responsible for creating a culture of equity in their institutions. 82 Steps to be taken at institutions include the following: (1) assessing whether care delivery is equitable; (2) prioritizing quality improvement interventions that address differential care delivery; (3) providing high-quality health equity and implicit bias training for healthcare professionals; (4) leveraging data for individual-level clinician feedback on health equity measures; and (5) making public statements of goals and actions to improve equity, in addition to internal commitments (Fig. 1). For example, during the COVID-19 pandemic, infectious disease, and antimicrobial stewardship leadership at one hospital recognized that access to monoclonal antibody infusion for COVID-19 management was inequitable. They leveraged an emergency department fast-track location and existing staff to make the treatment available for an underserved community. Reference Mena Lora, Echeverria and Lindsey11
Sustainable measures to mitigate disparities require accountability. Public and private institutions, including societies dedicated to healthcare epidemiology and antibiotic stewardship, have made public declarations of diversity equity and inclusion commitments. 83,84 Yet, without high-quality data collection and publicized data reviews, accountability may not be feasible for health systems. Reference McGrath, Logan and Deloney10 Additionally, the validity of SDOH, race, and ethnicity data entered into the electronic health record (EHR) have often been called into question, creating challenges for collecting and interpreting HAI inequity data. Reference Agawu, Chaiyachati, Radack, Duncan and Ellison75 However, interventions to correct these patterns might have limited impact in the absence of data validity tools for EHR systems to capture accurate data points. Despite these challenges, healthcare institutions can still develop anchor missions focused on addressing inequities for their local communities. For example, a Chicago-based health system crafted a multipronged framework that named racism and poverty as targeted causes of inequities. They embarked on a health equity mission to invest locally, collaborated with their surrounding community across all care spectrums, and they developed performance improvement plans to improve their patient outcomes. Reference Ansell, Oliver-Hightower, Goodman, Lateef and Johnson85 The level of commitment to equity may not be replicable for every institution, but we recommend that institutions identify and tackle a singular equity mission that is achievable and feasible within an established timeline. Healthcare system and facility leadership should be purposeful in recruiting a diverse and skilled workforce in healthcare epidemiology, infection prevention, and antimicrobial stewardship. Institutions can frequently conduct equity reviews and proactively correct identified deficiencies.
Public health systems
Public health engagement at the federal, state, and local levels is needed to address health inequities (Fig. 1). National, state, and community policies, structural inequities, and differential access to reliable information sources are important factors. The COVID-19 pandemic revealed the need for future public health initiatives to address systematic inequalities that can perpetuate and lead to differences in population and individual outcomes. Reference Li, Cai, Mao, Cheng and Temkin-Greener9 Action steps for public health include the following: (1) requiring surveillance and research activities that include health equity objectives and capture the needed data to support decision making and implementation science to address inequities; (2) providing necessary analytic resources to help characterize health inequities at the national, community, healthcare system, and facility levels to provide a compass for where action is needed; (3) communicating health information effectively to a variety of different audiences and health literacy levels; (4) facilitating access to subject matter expertise in healthcare epidemiology, infection prevention, antibiotic stewardship in health departments across the country; and (5) incorporating a health equity lens into guidance and policies for healthcare epidemiology, infection prevention, and antibiotic stewardship implementation. Regulatory and accreditation partners, such as The Joint Commission, can facilitate policy change. For example, in 2023 new health equity standards were released by The Joint Commission to establish a new baseline of equitable delivery of healthcare. 86
In conclusion, inequities in healthcare occur at every resource level. Steps to advance health equity should be considered at every level, whether a well-resourced health system or a rural critical-access hospital. Advancing health equity includes delivery of safe and equitable patient care and recruiting individuals with diverse backgrounds to healthcare epidemiology, infection prevention, and antimicrobial stewardship career paths.
