Critical Appraisal of Cross-Cultural End-of-Life Care

Research Problem and Clinical Significance

The clinical problem and dearth of research that led to this study were directly connected to a clear understanding that insufficient clinicians possessed cultural competency, particularly when caring for patients receiving end-of-life treatment. However, there was no clear sense of how to address this gap. The fundamental issue at stake was how cultural competency could improve end-of-life care and what services needed to be available to clinicians to enhance healthcare delivery and patient outcomes. As the researchers assert, "Thus the risk for cross-cultural misunderstandings surrounding care at the end of life is also increasing. Studies have shown cultural differences in attitudes toward truth telling, life-prolonging technology, and decision-making styles at the end of life" (Kagawa-Singer & Blackhall, 2001). These observations illuminate clearly the necessity of the study and the relevance of the overall research problem.

The researchers effectively established the significance of their study by clarifying how end-of-life care represents a truly difficult time for patients and their families. It can be an absolutely terrifying experience, and the cultural traditions people are accustomed to can be powerful in making them feel safe and comforted. This cultural alignment can also help clinicians feel that they are providing a higher level of care that is more specific and effective. Human suffering at the end of life is multifaceted—it includes not just prevalent pain but also the uncertainty of the unknown. Allowing patients to engage in cultural or religious traditions allows them to feel reassured and can provide comfort for family members who are also suffering. Too many clinicians overlook the suffering experienced by relatives during end-of-life care, making this research particularly timely and important.

The purpose of the study was to determine the best way for patients and clinicians to navigate pressing and difficult issues in cross-cultural care and to illuminate what those issues were. The study was designed to answer several specific research questions. What are the primary issues and challenges in cross-cultural care during the end of a patient's life? What cross-cultural issues emerge for relatives of a patient during the end-of-life period? What are the best ways to assist clinicians in learning to identify these issues? What are the most effective means of addressing these issues in an immediate, detailed, and sensitive manner?

Study Purpose and Research Questions

Questions of this nature were specific and nuanced, helping to inform the study while illuminating its overall purpose. The qualitative methods established were extremely relevant to the entire research endeavor. According to Kagawa-Singer and Blackhall, the basic structure of the study was as follows: "Using 2 case studies of patients, one of an African American couple in the southern United States and the other of a Chinese-American family in Hawaii, we outline some of the major issues involved in cross-cultural care and indicate how the patient, family, and clinician can navigate among differing cultural beliefs, values, and practices" (Kagawa-Singer & Blackhall, 2001). This demonstrates both the relevant manner in which the study was created and how it directly pertained to the research needs that the overall objectives had established.

The literature review that the study's authors cited was comprehensive and nuanced. The authors primarily referenced other qualitative studies relevant to the established focus. Most importantly, the authors demonstrated that a clear dearth of research existed in this arena of inquiry. All cited research articles were current at the time the authors wrote the study. While the authors did not explicitly discuss weaknesses or limitations in available studies, they effectively demonstrated how many existing studies were one-dimensional or simply not specific enough to address the particular needs this issue presented.

Literature Review and Research Foundation

The literature review was as comprehensive as could be expected for its time period and addressed all relevant studies appropriate to mention during that period. By grounding their work in existing qualitative research, the authors established a foundation for understanding cultural dimensions of healthcare and justified the need for more targeted inquiry into cross-cultural end-of-life issues.

Methodology and Theoretical Framework

While the authors did not explicitly state the perspective from which the study was developed, they clearly alluded to it throughout their work. The study's perspective was grounded in the clinician's viewpoint—specifically, how clinicians address the cultural care needs of people from cultural groups with which they were generally unfamiliar. No grounded theory method of qualitative inquiry was demonstrated, nor were diagrams presented. However, given the simplicity of their methods and research approach, these additions were not necessary to achieve their aims.

A framework was delicately developed from the study findings. In this study, the researchers found that "Skilled use of cross-cultural understanding and communication techniques increases the likelihood that both the process and outcomes of care are satisfactory for all involved" (Kagawa-Singer & Blackhall, 2001). This finding emerged directly from the case study analysis and provided an actionable principle for clinical application of cultural competence. The researchers offered in-depth explanations about how clinicians can use the study's findings to better inform their practice and provide more nuanced cultural care to patients during this difficult time. Their use of evidence is detailed, specific, and revelatory in advancing both theoretical understanding and practical clinical wisdom.
