Healthcare-associated infections (HAIs) in the acute care setting occur after a patient is admitted for 48 hours or longer. These infections include central line-associated bloodstream infections (BSIs), catheter-associated urinary tract infections (CAUTIs), surgical site infections, ventilator-associated events, and clostridium difficile infections (CDIs). Reference Argamany, Delgado and Reveles1,Reference Monegro, Muppidi and Regunath2 Studies estimate that 4% of patients admitted to acute care hospitals will experience an HAI. Reference Magill, Edwards and Bamberg3 This burden in the United States amounts to 648,000 patients with 721,800 infections a year. Reference Magill, Edwards and Bamberg3 There is novel data suggesting that patients of color experience higher rates of HAIs compared to White inpatients. Reference Bakullari, Metersky and Wang4,Reference Chen, Khazanchi, Bearman and Marcelin5

The association of race and ethnicity to specific infections and outcomes is published. Reference Argamany, Delgado and Reveles1,Reference Bakullari, Metersky and Wang4–Reference Gualandi, Mu and Bamberg7 Researchers reported an increased BSI risk in non-Hispanic African Americans when compared to non-Hispanic Whites (hazard ratio 1.31, 1.02–1.69). Reference Jeon, Muennig, Furuya, Cohen, Nash and Larson6 White patients experience higher incidence of CDI than African American patients, though African American patients with CDI experience higher mortality, more cases of severe CDI, and longer lengths of stay. Reference Argamany, Delgado and Reveles1 Asian American and Hispanic patients have higher rates of CAUTI than Caucasian patients. Reference Bakullari, Metersky and Wang4 African Americans have higher rates of hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) infections. Reference Gualandi, Mu and Bamberg7

In addition to race and ethnicity as influencers of HAI incidence and outcomes, English as a second language also impacts inpatient outcomes. Limited English proficiency (LEP) increases risk for hospital readmission and increases risk of mortality in patients with sepsis. Reference Jacobs, Prasad, Fang, Abe-Jones and Kangelaris8

We evaluated healthcare workers (HCWs) knowledge and perceptions of racial and ethnic inequities related to HAIs and hospital outcomes.

Methods

We utilized a voluntary, anonymous survey with 8 Likert scale questions. Survey questions reflected published data identifying racial and ethnic disparities in HAIs. The Likert scale offered 5 responses, including 1 neutral response. After institutional board review approval, electronic surveys in REDCap form were distributed via e-mail at an academic medical center. REDCap is a data management system with the ability to collect, store, and export responses to analysis software. Surveys were distributed to care partners, respiratory therapists, radiology technicians, mid-level providers, nurses, medical doctors, nursing students, and medical students. E-mail address pools were provided by the respective administrative staff. Only HCWs in adult surgical and medical intensive care units and general units were included. No demographic data such as age, race, or ethnicity were recorded. The surveys were distributed four times in 1-week intervals between August and October 2022.

Results

Respondents completed 370 surveys for a response rate of 12.2%. Self-identified roles included medical doctor (MD) (106), registered nurse (RN) (98), mid-level provider (61), care partner (15), MD student (25), radiology technician (5), respiratory therapist (16), RN student (17), and other/did not indicate (27).

Aggregated survey responses are presented in Table 1. In terms of LEP, 87% of respondents agreed that LEP increases risk for hospital readmission. Approximately 66% of respondents agreed that LEP increases risk of mortality in patients with sepsis.

Table 1.

Survey responses

In terms of HAIs, most respondents were unsure of racial and ethnic disparities affecting patient outcomes. Most (65.9%) were not sure if African Americans have higher rates of hospital-acquired MRSA infection and only 25.4% agreed. Most respondents (65.9%) were unsure if African Americans have a higher risk of hospital-acquired BSI than Caucasian patients. Two-thirds of HCWs were unsure if Asian and Hispanic patients have higher rates of CAUTI compared to Caucasian patients.

Only 12.1% of respondents agreed that Caucasian patients have higher rates of CDI than African American inpatients. Approximately half of respondents were unsure if African Americans have a higher risk of severe CDI and related mortality, 55.7% and 50.8%, respectively.

Discussion

Most HCWs were not aware of the influence of race and ethnicity in the prevalence of HAIs and associated outcomes. Only 25.4% of participants agreed and 65.9% were unsure that African American patients have increased risk of MRSA infections compared to White patients. Nevertheless, African American patients have a relative risk of 3.22 (95% confidence interval [CI], 2.35–4.35) for hospital-onset MRSA infection. Reference Gualandi, Mu and Bamberg7 African American and Hispanic hemodialysis patients are at higher risk for Staphylococcus BSIs. Reference Rha10 Similarly, 66.7% of HCWs were unsure if Asian American and Hispanic patients have higher rates of CAUTI compared to Caucasian patients. This disparity has been previously described in the literature and is potentially related to language barriers. Reference Bakullari, Metersky and Wang4

The survey revealed an overall lack of awareness of racial disparities in CDI. Only 12.1% HCWs agreed that Caucasian people have higher rates of CDI, nevertheless Caucasian patients make up 90% of cases. Reference Argamany, Delgado and Reveles1 Most HCWs surveyed were unsure if African Americans have high risk for severe CDI and death. Caucasian patients make up overwhelming most CDI, but African American patients have a higher risk of both mortality and severe CDI. Reference Argamany, Delgado and Reveles1

We are the first to report HCW perceptions of the impact of health inequity on HAI risk and outcomes. At the individual HCW level, we observed a lack of provider awareness of HAI risks in minority groups. HCWs not being aware of increased risk for HAIs in minority groups compared to Caucasian patients may perpetuate health inequity and worsen patient safety outcomes.

The primary study limitation is a low response rate. Each recipient had the opportunity to complete the survey over a 4-week period. We do not believe that additional attempts beyond four cycles of survey distribution will increase response rate significantly. Additionally, this is a single academic center study design. These data may not be generalized. Study strengths include using a voluntary, anonymous survey tool, and a diverse distribution of HCW roles.

Nonwhite patients experience higher rates of HAIs. This includes CDI, hospital-acquired BSI, and CAUTI. We report a lack of HAI racial disparities awareness by HCWs in a single-center survey. This study is the first to our knowledge to assess HCWs’ knowledge of health inequity and HAIs. Future studies are needed to better understand this trend and to define strategies for heightened awareness of HAI inequities.
