Professional Interpreters and LEP Patient Communication in Diabetes Care
This paper examines whether the use of professional bilingual interpreters improves provider-patient communication and health outcomes among Limited English Proficient (LEP) elderly Hispanic diabetic patients. Using a pre-test/post-test design with a sample of 40 patients aged 50–75 at a Los Angeles Wellness Center, the study compares outcomes before and after replacing ad hoc family interpreters with professional interpreters over a three-month period. Key measures include provider-patient communication scores, glycemic control (A1c >9%), and medication adherence. Results indicate that professional interpreters significantly improve communication scores, interpersonal care, health education, and glycemic control, underscoring the importance of linguistic intervention in healthcare delivery for LEP populations.

What makes this paper effective
- The paper presents a clearly defined, testable research question tied directly to a measurable clinical outcome — medication adherence and A1c improvement — making it highly focused and practical.
- The use of a pre-test/post-test design with paired sample t-test analysis gives the study a structured evidentiary foundation, and the inclusion of demographic data in Table 1 strengthens the transparency of the sample description.
- The paper honestly acknowledges its limitations (small sample, no control group), which adds credibility and models appropriate academic humility.
Key academic technique demonstrated
The paper demonstrates effective use of quantitative comparison tables to support narrative claims. Each table (2–5) is introduced with a clear contextual statement, and the discussion then synthesizes the statistical findings into plain-language conclusions — a strong technique for bridging data and argument in health sciences writing.
Structure breakdown
The paper opens with an abstract and overview establishing the clinical problem. A purpose statement narrows the focus to a specific research question. The methods section covers population, sample, instrumentation, data collection, variables, and design. Results are reported through five tables with accompanying analysis. The discussion is divided into conclusions, limitations, and implications — a clean IMRaD-adjacent structure appropriate for an applied health sciences project at the graduate level.
Overview
Provider-patient communication is an important factor in enhancing patient outcomes in the modern healthcare environment. Elderly Hispanic immigrants and Mexican Americans are among patient populations facing relatively high rates of diabetes. Sentell & Braun (2012) contend that the prevalence of diabetes among Hispanic communities — for both diagnosed and undiagnosed patients — is approximately 18.3%. These populations are predisposed to diabetic disorders due to several factors, including limited health knowledge, lack of access to resources, and cardiometabolic mechanisms (Detz et al., 2014).
Since most of these patients are Limited English Proficiency (LEP) patients, they experience tremendous communication challenges when seeking healthcare services for their diabetic conditions. Communication between healthcare providers and LEP patients is significantly affected by language barriers, even when family members are used as ad hoc interpreters. This project examined whether the use of bilingual interpreters helps to improve adherence to treatment procedures and provider-patient communication among diabetic LEP patients. The project is significant in helping determine the effectiveness of linguistic intervention in the administration of healthcare services.
Purpose Statement
The purpose of this project was to examine whether the use of bilingual interpreters helps to enhance medication compliance among LEP diabetic patients within a three-month period. The project was conducted on the premise that the use of family members as ad hoc interpreters has proven ineffective in enhancing medication compliance among LEP diabetic patients. The project therefore sought to determine whether using bilingual interpreters and language concordance would improve treatment adherence among LEP diabetic patients.
The research also sought to establish whether using bilingual interpreters and language concordance could reduce glycosylated hemoglobin A1c above 9%, and whether using bilingual interpreters would improve communication between providers and patients by an average of more than 10 points. The guiding research question was: "In Spanish-speaking diabetic individuals aged 50–75 years, would the use of a bilingual interpreter during provider visits, compared to utilizing family members as interpreters, improve medication adherence over a three-month period?"
