Using Evidence in Health and Social CarePDF
ACP J Club. 2001 May-June;134:A20. doi:10.7326/ACPJC-2001-134-3-A20
The aim of Using Evidence in Health and Social Care is to encourage health care practitioners to ask 2 questions: What counts as evidence, and is this research true for me, in my setting? The book's self-declared target audience is practitioners in health and social care “who want to read research and apply it in practice and not for people who want to do research themselves.”
This book, like any overview of a large subject, is likely to please some of the people some of the time and leave everyone just a little dissatisfied. Although it claims to be aimed at the broadly defined “practitioner,” it seems better suited to students of the health-oriented social sciences and is written from a social science perspective. The text is one used by the Open University School for Health and Social Welfare for the course on critical practice in health and social care.
For medically oriented health care practitioners, this book offers insight into qualitative methods that are more common to the social sciences. It challenges those who are steeped in quantitative methods to think more broadly about “what evidence is” (or what can be known for sure). It will also challenge them to critically appraise the validity of this type of evidence.
Unfortunately, not all of the chapters are of interest, nor are they uniformly well written. For example, the first chapter, “Ways of Knowing,” is a treatise on “what can be known for sure” and is full of postmodernist jargon. My initial reaction, as a busy practitioner whom the authors claim to be targeting, was to throw the book across the room. However, as I continued through subsequent chapters, I learned that the necessity of first considering what evidence is becomes a central theme in critically appraising both evidence and methods for specific issues in specific settings. The logic of beginning with this chapter became obvious, and I relented somewhat in my initial harsh appraisal. My concern remains, however, that the opening chapter may deter busy health care practitioners from persevering with the rest of the book, unless they are taking the course or writing a review.
Why do I not dismiss this book immediately as having no interest to medically oriented health care practitioners? I suspect that practitioners with a social science background might find the initial chapters, such as “Making Sense of Surveys” and “Understanding Experimental Design,” a comfortable and nonthreatening overview of quantitative methods. In addition, a basic but useful list of types of survey bias is included along with an excellent discussion of why consumer satisfaction surveys are poor indicators of a system's performance. Furthermore, I found that the chapters “Interpreting Meaning” and “Using Action Research” were approachable and enlightening overviews of the continuum of collaborative, interpretivist research methods. Excellent examples of this method were used as a way to elucidate values and meanings that may be unique to particular situations. These methods not only answer questions but also may be used to frame the relevant question and bring about change in processes or organizations. Also included are excellent practical discussions of using these methods rigorously to provide high-quality evidence.
Using Evidence in Health and Social Care challenges one to think of evidence and its validity in a wider context than that emerging from quantitative methods. I recommend specific chapters of this text for health care practitioners who want an accessible overview of qualitative, collaborative, participatory, and interpretivist research methods.
