Abstract

Introduction: The US Latino population is projected to double over the next 50 years while the proportion of Latino physicians is expected to decrease over the same interval. Spanish curricula within medical schools are common but rarely assess learners for proficiency and are often not incentivized. Family physicians are well positioned to promote the effective delivery of culturally and linguistically appropriate care to Latino patients with limited English proficiency (LEP). Our aim was to develop a replicable, incentivized, medical Spanish curriculum to promote fluency.

Methods: We developed a peer-taught, interactive, case-based medical Spanish curriculum for fourth-year medical students at a single medical school. All fourth-year medical students were eligible to enroll. Seventeen students completed pre- and postintervention questionnaires to rate their self-efficacy in medical Spanish comprehension and vocabulary. At the end of the course, students were also assessed for oral Spanish language skills by a standardized patient (SP).

Results: Students rated themselves as having improved at completing nearly all components of the medical interview and physical in Spanish after completing the course (15/16 tasks, P<0.001).

Conclusion: This peer-led medical Spanish course shows promise as a feasible and sustainable curriculum for teaching medical Spanish and assessing fluency among fourth-year medical students. Establishing a cohort of peers as teachers addresses concerns about cost and reduces the need for faculty support.

Introduction

The Spanish-speaking population in the United States is projected to double over the next 50 years.1 Less than 6% of non-Hispanic white physicians report speaking Spanish compared to 69%-92% of Latino physicians; however, the Latino physician rate has fallen over the last 30 years.2 Language discordance between patients and providers has been linked to more adverse events, longer hospital stays, decreased access to care, and poorer quality of care.3-5 Family medicine’s patient-centered, biopsychosocial approach to care is amenable to important medical and cultural considerations within LEP groups, in which language has been noted to be a significant barrier to effective care.6

One solution to the dearth of Spanish-speaking physicians involves Spanish training in medical school. A 2015 survey found that 66% of US medical schools offered curricula to develop Spanish speaking skills. A majority used multiple teaching styles and involved patient encounters. However, many of these programs lacked formal assessment of oral language proficiency, and only 62% incentivized participation with school credit.7 Credit for participation may be viewed as an important incentive for learners who must weigh the relative merits of limited elective time within their medical school curriculum.

We used a framework for curriculum development in medical education and a medical Spanish text to develop a peer-led, interactive, credit-based medical Spanish course for fourth-year medical students including an oral assessment of medical Spanish fluency (Table 1).8,9 Our purpose was to improve students’ self-efficacy and fluency in medical Spanish. The goal of this peer-led program was to overcome disadvantages inherent in faculty-led curricula including recruitment, hiring, and compensation. Near-peer teaching has been shown to create a favorable learning environment and offer education to students on their own cognitive level.11

Methods

The curriculum (Table 2) was piloted at Virginia Commonwealth University (VCU) School of Medicine (SOM), a public university located in Richmond, Virginia. The VCU SOM enrolls approximately 200 students in each matriculating class, of which approximately 3% identify as Hispanic, Latino, or of Spanish origin. Richmond currently has a population of approximately 250,000, and recent projections suggest the Hispanic population will grow to nearly 90,000 in the next 20 years.12  

We identified a Spanish-fluent faculty member (M.H.R.) with prior experience developing a medical Spanish course to serve as an advisor. The Office of Student Affairs provided oversight for student registration and credit for course completion. Two volunteer peer instructors with nonnative Spanish fluency taught the course. Both participated in the development of content and instructional methods used in the curriculum. The advisor knew the instructors’ level of Spanish proficiency. No incentives were provided to instructors. The course and its curriculum were reviewed and approved by the VCU SOM Curriculum Council.

Learner enrollment was solicited by email. All fourth-year medical students (n=192) were eligible to participate regardless of level of Spanish proficiency. Participation was incentivized using elective course credit that could be used toward graduation requirements. The course was offered in two separate 4-week elective blocks, for a total classroom time of 12 hours per block.

To assess the impact of the curriculum, a single group pretest/posttest design was used. We developed a survey to rate self-efficacy for each of the curricular objectives using a Likert-type scale.13 Free-response questions allowed students to elaborate on prior Spanish education and deliver feedback. The content of the survey was developed to mirror the objectives but was not formally validated. We also wrote a single-case Objective Structured Clinical Examination (OSCE) using a certified medical Spanish interpreter as the SP. The interpreter provided verbal feedback and formally assessed student performance using the Student Oral Language Observation Matrix (SOLOM),14 a five-item instrument designed to rate students’ comprehension, fluency, vocabulary, pronunciation, and grammar on a four-point scale (1 indicating poor performance and 4 indicating optimal performance). The OSCE was conducted the day after the final classroom session, and the survey was due within 1 week of course completion. The VCU Institutional Review Board granted the study exemption.

Results

Twenty learners were divided equally between males and females. Seventy-five percent (n=15) had some background in Spanish while 25% (n=5) had never taken any Spanish classes. Of those who had a background in Spanish language, 67% had completed high school-level coursework.

Paired t-tests were used to examine statistical differences between pretest and posttest scores. Statistical significance was set to P<0.05. IBM SPSS version 24 (Armonk, NY) was used for all statistical analyses. All participants who completed both surveys (n=17) reported improved medical Spanish ability across all abilities. The mean score across all pretest abilities was 1.60 (SD: 0.64) and the mean score across all posttest abilities was 3.38 (SD: 0.56; Figure 1). Significant improvements (P<0.001) in ability were made in all categories except for introductions (P=0.086). Students also reported improved confidence at performing all aspects of a history and physical, with mean improvement across all queried domains of 1.39 (SD 1.13; Figure 2).

Fourteen students participated in the SP encounter. There was no statistically significant correlation between subject postest rating of ability and subject SP score (using Spearman rank). There were no significant differences in SP encounter scores between the two blocks across all five domains.

In written feedback, students praised the variety of educational strategies and the authenticity of the SP encounter. They requested more class sessions and more time discussing cultural determinants of health. All students reported that it would be helpful to have some Spanish knowledge prior to taking the class.

Conclusions

Students who participated in the pilot curriculum had improved self-ratings and demonstrated markers of Spanish fluency in an SP case. The use of near-peer instructors coupled with provision of elective credit may help facilitate participation and overcome barriers previously cited in similar courses.7,15

Students’ average self-confidence ratings at medical Spanish tasks improved but did not reach the maximum score by the end of the class, suggesting an honest self-assessment. We suspect the SP encounter allowed students to reflect on their abilities; however, having the SP feedback prior to completing their evaluation of the course may have influenced these ratings of self-confidence. Accurate self-assessment of fluency is extremely important, as overestimation may lead physicians to undertake encounters without medical interpreters, cause medical errors, and damage the physician-patient relationship.16-18 Because of this issue, we emphasized the importance of considering one’s own limitations and recognizing when certified interpreter services are warranted, especially for those who completed the curriculum.

Reuland et al suggest that the optimal medical Spanish curriculum is longitudinal, tailored to individuals’ Spanish proficiency, and contains immersion activities.19 We aimed to develop a course that could meet these criteria with time and support. After the success of this pilot program, we incorporated mandatory, longitudinal use of language learning software as a complement to classroom-based teaching. We hope that as student participation increases, we can specifically tailor blocks to students’ preexisting Spanish proficiency.

Our small sample size limits our ability to conduct multivariate analysis and adjust for confounders. We were unable to compare the group that received peer teaching with a control faculty-led group. In addition, implementation at our single institution limits the ability to generalize to other sites. We hope that repeat iterations of this course can find correlation between subjective self-rating of medical Spanish ability and SP ratings. We recognize that a major limitation of this study is the reliance on a nonvalidated self-assessment survey for the majority of our data. Our hope is that with repeat iterations of this course, instructors could gather data on internal consistency of our survey instrument and calculate interrater reliability from repeated SP assessments.

In future years, the curriculum will be strengthened by a preintervention oral examination and increased focus on the diverse groups that comprise Latino culture. Our chapter of the Latino Medical Students’ Association helped us identify volunteer instructors in advance of upcoming academic years and will continue to sponsor and sustain the elective. We lacked objective assessment of the fluency of our instructors; longitudinal comparisons of instructor fluency and student outcomes are ripe for further investigation. Other instructor characteristics such as enthusiasm for material and engagement with students may also affect performance; however, these variables are more difficult to capture.

Working to improve Spanish language proficiency amongst future providers and to minimize language discordance has increasing importance due to the growing Latino LEP population and the association of language discordance with adverse outcomes. We believe other medical schools can adapt our curriculum to teach a larger cohort of medical students and improve outcomes for future patients.
