Introduction to Healthcare Research for Evidence-Based Practice
Introduction
This book is about research in healthcare, seen principally from the viewpoint of students undertaking pre-registration and postregistration educational programmes. We are both active healthcare researchers and are passionate believers in research by healthcare professionals (HCPs) for the benefit of the patients and clients we serve. Our own background is principally in mental health nursing, although, as teachers and researchers, we have widened the scope of our work beyond a purely mental health focus. Likewise, as researchers we have typically worked in multidisciplinary research, with the broad range of other HCPs, with medical practitioner researchers and with researchers from a range of non-clinical disciplines. In preparing this book, we have sought to make it relevant to colleagues from across the disciplines, and we hope this comes over in the material that follows. We both started to get interested in research from early on in our clinical careers, and did a good deal of research while still mainly working as clinicians. The real reason we started in research was because we were interested in whether the things we did with patients and clients made a difference to their experiences of illness, recovery and health. If you have picked up this book, we guess you have a similar interest, and we hope we can work with you in developing that interest and finding ways you can translate your ideas into practical projects, whether these be through your own research or your examination of the research literature to inform your practice.
In the following pages, we will try and take you through the various elements of undertaking a piece of research. Even if you do not have to do research yourself as part of your educational course, this book is still for you for three reasons. First, much of the material we present is
