THE DESIGN AND PRESENTATION OF A CASE STUDY PETER J TUCHIN B.Sc., Grad.Dip.Chiro., Dip.OHS. * ROD BONELLO B.Sc., D.C., D.O., M.H.A. † INTRODUCTION previous publications by the author or if there are other publications in the area research that is applicable to the Case studies are a much maligned area of scientific grant. For example, with an Australian Spinal Research publication. However, they do form the initial basis of Foundation grant for chiropractic and migraine, a literature scientific knowledge, which can lead to further hypothesis review revealed only one large randomised controlled for investigation. trial, and only a few case studies. This can make the success of the grant application less likely because there is There are over 2500 chiropractors/osteopaths in Australia little support for the need to research the area, as well as with an estimated 15 million patient visits per year (1) . Yet few indications that research will reveal any benefits (3) . published case studies involving chiropractor/osteopath patients are minimal. Chiropractors/osteopaths often have However, by far the most important aspect is documentation many interesting cases to discuss and present, however, of anecdotal evidence of clinical improvement of individual some practitioners are uncertain of the best procedure to patients. If well presented case studies with strong objective publish these case reports. As a consequence, it would evidence can be published in sufficient numbers, then this appear that many conditions that have anecdotal support, becomes scientific evidence. have little if any scientific support (2) . CASE STUDY PRESENTATION One purpose of this paper is to present the standard features of case studies and to develop a criteria check-list The abstract precedes the body of the paper. It must be to evaluate the quality of case studies published. In concise and clear, as many readers will determine whether addition, the paper is designed to facilitate the publication they read the whole paper on the strength of the abstract. of more case studies by chiropractors/osteopaths about In performing literature reviews, many researchers the patients they consult in their practices. frequently scan hundreds if not thousands of abstracts. Therefore, a well structured abstract may determine the Practitioners will gain more information about conditions usefulness of the whole paper. that they encounter through a number of mechanisms. First, by reviewing the literature on the condition when A structured abstract is usually required for case study they prepare to write the case study.
