Effective communication between patients and physicians is critical to successful health outcomes. Limited English proficiency (LEP) is defined by the U.S. Census Bureau as anyone who reported speaking English less than very well. There are more than 25 million people (approximately 1 in 11 Americans) with LEP in the United States.1 LEP patients are among the most vulnerable populations. The language barrier experienced by LEP patients hinders effective communication, impedes access to care, and impacts health care delivery.6 Research has shown that LEP patients are likely to consume more health care services7; however, they receive lower quality of care and have poorer outcomes compared to English-proficient patients on various measures: understanding of treatment plans and diseases processes, satisfaction, and incidence of medical errors.3,5, This language-based inequity in LEP patients also hampers shared decision-making, a process in which physicians and patients make decisions together, balancing the risks and benefits with patient preferences and values.6-7 Shared decision-making is encouraged by the Institute of Medicine and US Preventative Services to foster patient autonomy and engagement.6 Similarly, the American College of Obstetricians and Gynecologists emphasizes the importance of creating a partnership with patients.7 Research indicates that patients want to be more involved in the decision-making process but might feel that they do not have the capability to do so.8 Furthermore, the ability of patients to engage in the shared decision-making process also depends on their health literacy. It is estimated that one-third to one-half of the U.S. adult population has low health literacy or a limited capacity to obtain, process, and understand the basic health information and services needed to make informed health decisions.8 While low health literacy affects individuals across the spectrum of socio-demographics, it disproportionately affects those with LEP.9 A knowledge gap exists in our understanding of LEP patients' roles in decision-making since most research on decision-making itself often excludes non-English speakers from study participation. The few published reports in the oncology literature have suggested that Latinas experience barriers to informed treatment decision-making related to literacy, language, and acculturation.2,8 Hawley ST et al. (2008), in a survey of 2030 women with breast cancer, found that Spanish-preferred Latinas were more likely to report too little involvement, higher dissatisfaction, and more regrets compared to English-preferred Latinas, African Americans, and Caucasians.9 Research has shown that patients who take a more active role in their care are often more satisfied, have a better understanding of treatment plans, and experience greater improvement in health and patient-centered outcomes than do passive patients.10 Therefore, understanding these preferences, particularly in an LEP population, is necessary to meet patients' decision-making expectations, navigate discussions about treatment options, and increase patient satisfaction with the decision-making process.
Understanding a patient's decision-making preference can help physicians meet their expectations and may increase patient satisfaction with the decision-making process.
