What are the steps to conducting a biomedical engineering literature review?

When planning a literature review, determining the type to produce is crucial. Will it be a narrative review, offering a broad, qualitative overview of existing research? Or a systematic review, providing a rigorous, methodical analysis of studies to answer a specific question? Perhaps a mini-review focused on a more concise summary of recent developments? Also, you might opt for a review featuring bibliometric analysis, which quantitatively evaluates the impact and trends within a body of literature. Each type serves different purposes and requires distinct approaches, making this decision foundational to your review's direction and scope.

Defining your scope is crucial for a focused and effective literature review in biomedical engineering. By clearly outlining your topic, research questions, and selection criteria, you set a solid foundation for identifying relevant studies. This step also ensures that your review is tailored to its intended purpose and audience, whether it's for academic, professional, or funding purposes, thus enhancing the clarity and relevance of your findings.

Effectively searching for sources is essential to a thorough biomedical engineering literature review. Utilizing databases like PubMed, Scopus, and Google Scholar ensures access to a wide range of peer-reviewed articles and publications. Expanding your search to include reference lists, citation indexes, grey literature, and expert opinions helps uncover additional or recent information. Employing specific keywords, filters, and search operators refines results, ensuring relevance and up-to-date content for your review.

Organizing the collected information is crucial for a comprehensive biomedical engineering literature review. Use reference management tools like EndNote, Mendeley, or Zotero to track bibliographic details and manage your sources efficiently. Summarize each source by noting the key points, methods, findings, implications, strengths, weaknesses, and gaps. Utilize matrices, tables, or mind maps to compare and contrast sources, helping to identify overarching themes and patterns in the literature.

Synthesizing the information involves analyzing and integrating the research from your sources to present a coherent narrative. Rather than just summarizing, evaluate and critique the sources, showing their interrelations and relevance to your research question. Identify gaps or limitations in existing research and explain how your work will address these issues, providing a clear context for your study.

Writing your report involves structuring your literature review according to specific guidelines, typically including an introduction, body, and conclusion. The introduction sets the context, states your research question, and outlines the themes. The body discusses existing research, organized by these themes. The conclusion summarizes the main findings, identifies research gaps, and justifies your study's relevance. Following this format ensures clarity and coherence in presenting your analysis.

Revising your report is crucial to ensure its clarity, coherence, and accuracy. Seek feedback from peers, supervisors, or editors and address their suggestions. Proofread for grammar, spelling, and citation errors, using reliable style guides for consistency. Utilize plagiarism detection tools to verify proper acknowledgment of original sources, ensuring your work is credible and professional.

Consider using visual aids, such as charts, graphs, and diagrams, to illustrate complex ideas and relationships in your literature review. These can enhance understanding and engagement for your readers. Additionally, keep abreast of the latest developments in your field to ensure your review remains relevant and up-to-date. Finally, be open to revisiting and updating your review as new research emerges, maintaining its value as a comprehensive resource.

A very nice addition to a literature review is a section dedicated to bibliometric analysis, including, for example, the quantitative analysis of total publication counts over time for a specific topic and its science mapping using co-occurrence graphs and clustering analysis.
