Of the 15 included studies, 13 (87%) were cross-sectional and 2 studies used cross-sectional survey data from health care providers merged with longitudinal data from patients. All of the studies sampled participants from the United States, and only 1 study included a small portion of participants from outside the United States. All of the studies used convenience sampling. Eleven studies (73%) sampled participants from a single city; the cities were all large urban areas (e.g., Atlanta, GA; Baltimore, MD; and Denver, CO). Only 4 studies sampled participants from multiple locations across the United States. Among health care professional participants, the response rates ranged from 28% to 84% (mean = 57%; SD = 18.6%), and 2 studies did not report response rates. Among the 6 studies that used patient participants, 2 did not report response rates; among the studies that did report them, they ranged from 47% to 75% (mean = 66%; SD = 12.8%).
All 15 studies were conducted in the United States, although country in which the research was published was not an exclusion criteria. Twelve studies sampled practicing health care professionals, which included physicians, nurses, and nurse practitioners in the areas of primary care, pediatrics, internal medicine, emergency medicine, and spinal cord injury. Three studies included medical, nursing, and pharmacy students as participants. The sample sizes for health professionals varied drastically, from 14 to 2535 participants. Five studies had fewer than 50 participants, and 9 studies had between 50 and 350 professional participants. In most studies, about 75% to 80% of professionals were White, followed by small but substantial proportions of Asian professionals (10%–30%) and small proportions of Black and Hispanic/Latino/Latina professionals (0%–10%). In most studies, the proportions of males and females were about equal; however, samples tended to have more female than male participants. Six of the 12 studies that sampled practicing professionals measured their professional experience, which showed that about half had less than 10 years of experience. National estimates of physician demographics have shown that 72% of physicians are male, 74% are White, 17% are Asian, 5% are Hispanic, 4% are Black, 29% have less than 10 years of experience, 32% have between 10 and 20 years of experience, and 39% have more than 20 years of experience. 40 However, the 15 studies in this review included physicians and other health care professionals from a variety of disciplines, which may account for the demographic differences.
Six of the 15 studies (40%) collected data from patients. Patient sample sizes ranged from 112 to 4794 (mean = 1399; SD = 1991), with 2 studies having about 3000 or more participants and 4 studies having between 100 and 300 participants. All 6 studies included Black patients, 4 included White patients, and only 2 included Hispanic/Latino/Latina patients. Most studies had larger proportions of female (about 60%–70%) than male patients. Patient samples consisted primarily of middle-age and older adults. Only 3 of the 6 studies reported information about patients’ socioeconomic status, which showed that most patients’ highest level of education was a high school degree and most had low to moderate incomes (i.e., < $35 000 per year).
Of the 15 studies reviewed, 9 examined bias against Black people compared with White people; 3 examined bias against both Black and Hispanic/Latino/Latina people compared with White people; 1 examined bias against Hispanic/Latino/Latina compared with White people; 1 examined bias against individuals with darker versus lighter skin tones; and 1 examined bias against Black, Hispanic, and dark-skinned individuals versus White or light-skinned individuals. Fourteen of the 15 studies used the Implicit Association Test (IAT) 41 to measure implicit bias. The IAT is a computerized categorization task in which participants sort stimuli (e.g., pictures, names, and words) into opposing categories as quickly and as accurately as possible. For example, a participant might demonstrate faster reaction times between negative words (e.g., nasty) and pictures of Black faces than White faces, which would reflect an association between negativity and Black Americans. To score responses on the IAT, a D score is calculated, which is an effect size. 42 When interpreting IAT D scores, 0 indicates no bias, positive scores indicate preference for White people over people of color, and negative scores indicate preference for people of color over White people. All 14 studies examined associations along the dimension of positive versus negative using words such as wonderful and peace versus words like horrible and evil. Of these studies, 4 also examined associations related to the medical context, such as patient compliance and cooperativeness. Only 1 study 25 did not use the IAT, but instead used sequential priming. In this method, faces were presented very briefly, at a subliminal level, followed by positive and negative words to be evaluated. Meta-analytic data suggest that sequential priming measures show evidence of validity similar to that of the IAT. 43
Of the 15 reviewed studies, 14 found evidence of low to moderate levels of implicit bias against people of color among health care professionals. Only 1 study reported no evidence of implicit bias against people of color. 34 Thirteen studies reported that health care professionals were more likely to associate Black Americans with negative words compared with White Americans. The D scores reported in these studies ranged from −0.10 to 0.62 (mean = 0.28; SD = 0.18). Two studies did not provide D scores, but found evidence of low to moderate bias against Black Americans in 42% and 43% of their samples of professionals. Four studies reported prevalence rates of anti-Black bias in their overall sample, which ranged from 42% to 100% (mean = 63.5; SD = 23.7). In sum, 13 of 14 studies examining implicit anti-Black bias found that health care professionals tended to possess low to moderate levels of negative associations with Black Americans.
Further, 4 studies found evidence of moderate anti-Black bias in health care professionals’ evaluations of Black Americans as patients, with D scores ranging from 0.22 to 0.30 (mean = 0.26; SD = 0.03). However, 2 studies also reported that their samples of professionals associated high-quality medical care, as opposed to low-quality care, more with Black Americans than with White Americans. 38,39 Thus, these 4 studies revealed that, overall, health care professionals associated Black Americans with being less cooperative, less compliant, and less responsible in a medical context.
Four studies reported evidence of moderate levels of implicit bias against Hispanic/Latino/Latina individuals compared with White individuals. Two studies did not report their D scores, but reported that about half of their participants demonstrated moderate to strong implicit bias against Hispanic/Latino/Latina individuals. 30,31 One study reported an overall moderate bias against Hispanic/Latino/Latina individuals relative to Whites on the IAT (D = 0.33). 26 Further, Bean et al. 25 reported that professionals tended to associate Hispanic/Latino/Latina people with noncompliance and risky behavior, and had general stereotypes of them (e.g., that they were unimaginative). These studies suggested that health care professionals possess implicit bias against Hispanic/Latino/Latina individuals at a level comparable to levels of implicit bias against Black Americans.
Finally, 2 studies reported moderate amounts of implicit bias among health care professionals against darker-skinned individuals compared with lighter-skinned individuals. 29,32 IAT D scores in these studies were 0.33 and 0.31, which are comparable to the D scores reported in other studies of implicit biases against Black Americans and Hispanic/Latino/Latina individuals.
To characterize the effect size in these studies, we performed a meta-analysis on the 13 studies that reported an effect size or sufficient information to compute one. The weighted mean effect size was d = 0.34, which is significantly different from zero ( z = 7.17; P < .001). Tests for heterogeneity of effects were not significant ( Q [12] = 3.94; P = .98) indicating a lack of heterogeneity across samples. Implicit bias scores were robust and showed little variability across studies, suggesting that this moderate effect size may provide a good estimate of the effect in the population of health care professionals.
Ten of the 15 studies examined the relationships between implicit racial/ethnic bias scores and particular types of health care outcomes. We chose to divide these outcomes into 4 general categories to succinctly summarize the literature: patient–provider interactions, treatment decisions, patient treatment adherence, and patient health outcomes. Within these categories the outcome data source (e.g., patient self-report, provider self-report, and medical records) varied. Five studies focused on patient–provider interactions. Four studies considered treatment decision-making and recommendations. Two examined treatment adherence, and 2 looked at health or mental health outcomes. Among the 80 associations between implicit bias and variables related to patient–provider interactions, 33 were significant or marginally significant. Among the 40 associations between implicit bias and variables related to treatment decisions, 7 were significant or marginally significant. Among the 5 associations between implicit bias and variables related to treatment adherence, 1 was significant. Finally, among the 11 associations between implicit bias and patient health outcomes, 3 were significant. We did not perform a meta-analysis on these associations because the 136 reported associations came from only 10 samples, which poses problems for the assumption that observed effects reflect independent estimates.
There were also differences in the ways implicit bias was measured and the presence of significant associations with health care outcomes. General good versus bad bias was the most common method used to assess bias; however, some studies attempted to tap more nuanced forms of bias in terms of compliant versus noncompliant, cooperative versus uncooperative, and high versus low quality of care. Among the 84 associations between general bias and health care outcomes, 26 were significant or marginally significant. Among the 102 associations between more nuanced forms of bias and outcomes, 18 were significant or marginally significant. Thus, the more general and perhaps visceral comparison, good versus bad, seemed more often to have an impact on health care outcomes.
Black patients perceived poorer treatment in domains such as patient centeredness, contextual knowledge of the patient, and patient–provider communication from providers who demonstrated implicit bias against Blacks on the IAT; Latino patients in the same study did not perceive poorer treatment in these domains, although higher percentages of physicians showed bias against them than against Black patients. 30 In another study, White and Black patients found physicians with anti-Black bias to be more dominant in their communication styles. Pro-White, anti-Black physician bias was associated with White patients feeling more respected by the physician. However, among Black patients, provider bias was associated with less respect from providers, lower levels of liking the providers, and less willingness to recommend their provider to someone else. They also reported longer visits and experienced their visits with the provider as being less collaborative. 32 Another study also found an association between implicit racial bias and verbal dominance by physicians during encounters with Black patients. 34 Pro-White attitudes among primary care physicians were associated with lower scores by Black patients on physician warmth and friendliness, as well as lower scores by physicians regarding their feelings of “being on the same team” with their Black patients. 37 Conversely, no significant associations were noted when vignettes were used to assess the impact of bias on medical student responses in terms of assessment of pain delivery or proper informed consent. 35
When treatment recommendation was used as an outcome, Green et al. 33 found that physicians demonstrating pro-White bias were less likely to recommend thrombolysis to Black patients and more likely to recommend this treatment of White patients. Among pediatricians, Sabin et al. 38 found no significant associations between implicit bias and treatment recommendations for pain control, urinary tract infection, attention deficit hyperactivity disorder, and asthma control. Yet in a similar study, Sabin and Greenwald 39 found pediatricians recommending the ideal management of pain at lower rates when responding to vignettes of Black patients as opposed to White patients.
Pro-White bias was associated with Black patients being less likely to fill prescriptions; however, this relationship was not found for Hispanic/Latino/Latina patients. 31 Another study did not find significant relationships between implicit bias assessed at baseline and Black patient treatment adherence at 4 and 16 weeks follow-up. 34
Two studies examined health and mental health outcomes: one with spinal cord injury patients and another with hypertensive patients. The study of physicians specializing in spinal cord injury found significant relations between implicit bias scores and patient health outcomes. 36 Psychosocial health outcomes (i.e., social integration, depression, and life satisfaction) for Black and White patients appeared to be negatively affected by the presence of physician bias in this sample. However, physical health outcomes (i.e., mobility, physical independence, and general health status) appeared uninfluenced by the presence of bias. Another study found no significant associations between implicit bias and hypertension outcomes among Black and Hispanic/Latino/Latina patients. 31
Results of this review suggest that implicit bias against Black, Hispanic/Latino/Latina, and dark-skinned individuals is present among many health care providers of different specialties, levels of training, and levels of experience. Mean IAT scores and prevalence rates of implicit racial/ethnic bias among the reviewed studies are similar to those documented using the general population. 44 In addition, the levels of implicit bias among health care professionals against Black, Hispanic/Latino/Latina, and dark-skinned people appear to be relatively similar across these groups. Virtually absent in the literature, however, is evidence-based information on how to reduce an individual health care provider’s bias.
The extant literature is also unclear on how implicit bias affects health care outcomes both through direct and indirect pathways. Results were mixed, as some studies reported significant relationships between implicit racial/ethnic bias scores and health care outcomes and other studies found no significant relations. Nonetheless, implicit bias appears to be more frequently associated with patient–provider interactions and relationships than other outcomes. These findings may imply a pathway by which patient–provider interactions mediate the relationship between provider implicit bias and patient outcomes in terms of treatment adherence and health status. Other factors not considered in this review, such as health care system characteristics, provider background characteristics, and patients with multiple minority identities, may mediate or moderate the ways in which provider attitudes influence patient–provider relationships and health outcomes.
This review also raises questions of how biases may interact in terms of intersecting identities. The patient and professional samples used were predominantly female. Because women in the general population have been shown to have lower levels of implicit racial/ethnic bias, 45 it is possible that the estimates of bias, both in attitudes and in outcomes, in the samples represented in this review are lower than if the samples of both patient and providers were more gender balanced. Likewise, women, regardless of ethnicity, are more likely than men to experience biased interactions and treatment in care. 46,47
Implicit bias toward people of color may indeed interact with other characteristics such as gender, age, sexual orientation, national origin, and disability status to produce differential treatment outcomes. There is evidence of implicit bias based on gender, age, sexual orientation, ethnicity, religion, and disability in the general population. 44 However, research on implicit bias in health care has tended to focus on race, and few studies have investigated bias related to other identity characteristics.
Findings from this review suggest that implicit bias may be activated under stressful working conditions. Health profession students demonstrated levels of implicit racial/ethnic bias similar to those of practicing providers; however, students’ bias may have been less likely to affect decision-making and outcomes than practitioners’ bias. Only 1 study examined the relationship between implicit bias among students and health care outcomes, but it found no significant relationships. 35 However, 8 of the 9 studies of practicing providers found significant relationships between implicit bias scores and health care outcomes. Perhaps the impact of bias becomes more pronounced as professionals progress through their health care training and career. Repeated instances of certain patient situations may become engrained as “truths” about an entire population group. For example, Hispanic/Latino/Latina patients often coming to appointments late may lead to a provider’s belief that this group does not take responsibility for their health care, and consequently the provider is generally less respectful and pleasant with future Hispanic/Latino/Latina patients. In addition, exposure to bias among providers’ peers may reinforce their bias, making them more likely to make treatment decisions that are based on racial/ethnic stereotypes rather than an individual patient’s medical status. There is evidence of cultural and institutional bias in health care settings. 48–50 Researchers seeking to develop and test interventions to decrease bias should consider multiple targets, including primary prevention for health profession students, interventions for practitioners actively working with patients, and systemic interventions that neutralize biases that have been institutionalized in health care settings.
Finally, the reviewed studies focused on relatively few health care specialties, making comparisons of implicit bias between areas of health care difficult. Nonetheless, 2 studies 38,39 of pediatricians in this review found that they had lower levels of implicit bias than other types of health care providers. Certain health care disciplines may be more prone to implicit bias. It is possible that certain types of training address problematic attitudes throughout the education period so that practicing professionals demonstrate lower levels of bias. Within medicine, examinations of the curriculum and comparisons by specialty may prove useful. Interventions for bias may look different according to the needs and realities of particular specialties. For instance, because of time pressure, critical care professionals may need more systemic interventions, whereas specialties such as internal medicine, pediatrics, or family medicine may benefit from a combination of both individual and systemic intervention strategies.
In sum, the current literature suggests that implicit racial/ethnic bias is present in health care and bias can affect health care outcomes. However, the current literature is not strong enough to make definitive statements about the impact of implicit bias because of the methodological limitations of studies in the literature.
We identified 5 prominent limitations among the studies reviewed. First, all but 2 of the studies used cross-sectional designs. Although cross-sectional designs are useful in determining the prevalence of a condition within a given population, they have limited ability to determine predictive relationships between variables. Because cross-sectional studies are conducted at 1 point in time, it is difficult to infer causality between a risk factor (e.g., exposure to a biased health care provider) and an outcome (e.g., a patient’s psychological distress).
A second limitation was the use of convenience sampling. Although convenience sampling may be highly feasible and efficient, it can lead to the underrepresentation or overrepresentation of particular groups within a sample. It is therefore unlikely that a convenience sample is representative of the population of interest, which raises questions about the generalizations that can be made from the findings.
Small sample size was a third limitation because the studies were estimating the prevalence of implicit bias and quantitatively examining the strength and direction of relationships between bias and health care outcomes. Eight studies had sample sizes of approximately 100 professional participants or less, and 3 of these studies had 15 participants or less. These small sample sizes raise the concern of whether these studies possessed enough statistical power to detect the prevalence of implicit bias in their sample and the effect of implicit bias on health care outcomes. In addition, certain statistical analyses in some studies relied on much smaller samples than the initially reported total sample size (e.g., Sabin and Greenwald 39 ), which reduces the chance of detecting a true effect.
A fourth limitation related to the measurement of implicit bias. Fourteen studies used the IAT to measure implicit bias. Although the IAT has demonstrated good internal consistency, with Cronbach alphas ranging from 0.70 to 0.90, 51 the instruments’ test–retest reliability has been criticized. 52 The relatively low test–retest reliability of the IAT, ranging from 0.25 to 0.60, 53 raises concerns about whether the IAT measures stable implicit attitudes or if other, nonattitudinal factors influence performance on the IAT. For example, contextual information such as whether a Black individual is presented in a positive or negative context influences the degree to which participants make negative associations with Black individuals. 54 Some researchers have also argued that performance on the IAT might be influenced by individuals’ knowledge or awareness about group stereotypes in a society rather than their personal attitudes. 55–58 Other researchers have argued that some effects of the IAT may be influenced by whether paired categories are similar in salience. 59,60 For example, images of people of color may be more salient to the average White participant because of unfamiliarity, whereas negative words may be more salient in general because of their affective nature. Thus, when 2 highly salient categories are paired (e.g., people of color and negative words), participants are quicker to respond than if categories different in salience are paired (e.g., White individuals and negative words). The IAT is the most widely known implicit measure but also the most controversial. 52,61
A final limitation was the narrowness in measurement of implicit bias. Most studies focused on bias against Black Americans. Few studies examined implicit bias against Hispanic/Latino/Latina Americans, and no studies examined bias toward other racial/ethnic minority groups, such as American Indians, Asian Americans, and Arab Americans. These groups also face health disparities, 1,4 and there is evidence of stereotypical and negative implicit attitudes toward these groups among the general population in the United States. 44 In addition, no study investigated implicit bias toward immigrants. Many people of color are also immigrants and may face a unique form of prejudice related to their race/ethnicity as well as their immigrant status. Finally, although Black versus White inequalities have tended to dominate the focus of race relations in the United States, Asian, Hispanic/Latino/Latina, and multiracial Americans are the fastest-growing racial/ethnic groups, 62 and examining bias toward these groups should not be neglected.
Implicit attitudes appear to be an important target for further research in health care; however, methodological limitations need to be addressed in future studies to more fully and accurately understand how implicit bias affects care and health. In addition, researchers will need to ask more nuanced questions and use more rigorous designs and analytic methods to fully understand the role, impact, and appropriate intervention strategies for implicit bias within health care.
In the future, cross-sectional studies should primarily be used to ascertain national estimates of implicit bias among health care providers, to examine correlational research questions, or to test exploratory hypotheses. Longitudinal studies are needed to examine causal relations between implicit bias and health care outcomes. Longitudinal studies could also provide information on changes in implicit bias over time throughout providers’ careers and could help identify appropriate intervention points and factors that affect the acquisition of implicit bias. Interventions to address implicit bias are emerging; to date, they are not well tested, although some intervention studies are in process. 63–65 To evaluate the efficacy and effectiveness of such interventions, researchers should use pretest–posttest cohort designs, well-matched intervention–comparison group pretest–posttest designs, and randomized control trials, which are the gold standard design for measuring intervention impact. Finally, multilevel study designs may be needed to address clustering concerns, such as providers being nested within medical specialties and care delivery sites. Likewise, if the unit of analysis is patients and their experience, patients can be nested within families, providers, and health care settings. Not accounting for clustering during analyses can lead to biased estimated standard errors and spurious results. 66 Multilevel studies also allow researchers to examine the influence of both provider and institutional bias on health care outcomes.
In terms of sampling, futures studies should strive for samples that are more representative. Research on implicit bias would be strengthened by more geographically representative samples of providers and patients. At this point, we know little about whether providers in particular regions are more likely to be influenced by implicit bias than those in other geographic regions. Sampling of providers could be stratified by geographic location or specialty. Although this review focused on bias among various health care professionals from different specialties and levels of training and experience, future researchers may want to focus on specific groups of providers, such as those from a particular discipline, to investigate training and professional socialization related to implicit bias. In terms of sampling patients, researchers may stratify on the basis of geographic location or patient type. The influence of implicit bias may differ between patients experiencing only acute health problems and those struggling with chronic diseases, or between pediatric and adult patients. When patients are sampled, every effort must be made to extend beyond convenience sampling. Sampling practices should attempt to include all patients, not just those who are easy to reach or those who are nonintermittent patients—patients may stop or avoid care because of discriminatory experiences. In addition, although costly and perhaps difficult to obtain, large national samples would allow for more accurate prevalence estimates of implicit bias among US providers. Large sample sizes also provide more statistical power, which is needed for multilevel modeling, multivariate analyses, and the detection of small or moderate effects in terms of associations between variables and group differences.
A comprehensive understanding of the role of implicit bias in health care will require converging evidence using a wider variety of well-validated implicit measures. Although the research reviewed here relied almost exclusively on the IAT to assess implicit bias, this test is only one of several well-studied implicit assessments. Sequential priming tasks are another well-validated class of implicit measures, and meta-analytic comparisons show that the average association between priming tasks and behavior ( r = 0.28) 43 is similar to the meta-analytic association between the IAT and behavior ( r = 0.27). 67 Sequential priming tasks include evaluative priming, 12 lexical decision tasks, and the Affect Misattribution Procedure. 68 Of these, the Affect Misattribution Procedure displays the highest reliability (meta-analytic average Cronbach α = 0.81) 69 and associations with behavior (meta-analytic r = 0.35). 43 Because each type of measure has unique strengths and weaknesses, future research should employ a broader array of measures to avoid systematic biases in results.
Future studies should also expand the assessment of implicit bias. Although health disparities are particularly prominent among Black Americans, inequities also exist for other people of color, including American Indians, Asian Americans, and Hispanic/Latino/Latina Americans. Thus, future studies should examine levels of implicit bias among providers regarding these groups and whether bias contributes to health disparities. Researchers should also measure bias based on social identity characteristics in addition to race/ethnicity, such as age, gender, socioeconomic status, national origin, sexual orientation, gender identity, religious orientation, and disability status. Bias can exist on multiple social dimensions, and patients with multiple minority identities may be particularly affected. In addition, measuring various demographic characteristics among patients and providers would allow more advanced hypothesis testing. For example, a patient’s gender may moderate the relationship between a provider’s implicit racial/ethnic bias and quality of care, and providers in some specialties may have significantly higher levels of implicit bias than those in other areas (e.g., emergency medicine physicians vs pediatricians).
Finally, findings from this review indicate that we are at the fetal stage of understanding what represents the construct of implicit racial/ethnic bias, how it functions in health care, and what it influences. Theory can be useful as we move forward in this area. However, of the 15 studies reviewed, only 3 were informed explicitly by theory (e.g., aversive racism theory). 27,31,37 The predictive utility of a theory depends on whether it can be applied to distinguish underlying processes and their respective effects on outcomes. Although implicit attitudes may influence a range of outcomes in health care, very few studies examined the relationship between implicit bias and the end result of care—patient health. Our findings suggest that greater conceptual clarity is needed for interpreting existing differential effects of implicit bias on behavior and patient health outcomes, developing new theories, and designing future studies. New intervention research questions for future studies to consider are on the malleability of implicit bias and the mechanisms for regulating the effects on behavior that contribute to racial/ethnic inequities in health.

1. INTRODUCTION. Although expressions of explicit bias have declined in the United States over time, implicit bias has remained unrelenting. Health care providers hold negative explicit and implicit biases against many marginalized groups of people, including racial and ethnic minoritized populations, disabled populations, and gender and sexual minorities, among others (29, 63).
Introduction. Bias is the evaluation of something or someone that can be positive or negative, and implicit or unconscious bias is when the person is unaware of their evaluation. 1,2 It is negative implicit bias that is of particular concern within healthcare. Explicit bias, on the other hand, implies that there is awareness that an evaluation is taking place.
Discussion. The evidence indicates that healthcare professionals exhibit the same levels of implicit bias as the wider population. The interactions between multiple patient characteristics and between healthcare professional and patient characteristics reveal the complexity of the phenomenon of implicit bias and its influence on clinician-patient interaction.

An implicit bias is an unconscious association, belief, or attitude toward any social group. Implicit biases are one reason why people often attribute certain qualities or characteristics to all members of a particular group, a phenomenon known as stereotyping. It is important to remember that implicit biases operate almost entirely on an ...
The concept of implicit bias, also termed unconscious bias, and the related Implicit Association Test (IAT) rests on the belief that people act on the basis of internalised schemas of which they are unaware and thus can, and often do, engage in discriminatory behaviours without conscious intent.1 This idea increasingly features in public discourse and scholarly inquiry with regard to ...
In addition to structural racism, implicit bias—defined as unconscious attitudes, positive or negative, toward a person, group, or idea—often leads to differential treatment based on perceived race. 2, 3 Implicit bias further restricts quality healthcare as a separate factor above and beyond inequities of structural racism.
A 2015 systematic review showed that low to moderate levels of implicit racial or ethnic bias were found among healthcare professionals in all but one of 15 studies.3 The results also showed that implicit bias was "significantly related to patient-provider interactions, treatment decisions, treatment adherence, and patient health outcomes."
