We have several suggestions for the next edition. First, we would group the chapters on how to conduct health services research as one section of the book, with applications of these techniques in another portion. There is, for example, a wonderful chapter on constructing validated scales that is buried after a chapter about measuring fatherhood propensities. Second, our sense is that the chapter authors were encouraged to provide a topic review and then to discuss their own research. The weakness in this technique is that it does not provide a sense of where this research falls in a continuum of research methods or link it to other related research methods. The examples override the approach, but the examples make the techniques real. Third, the chapters could benefit from an outline, learner objectives, and a standardized format. The headings are easy to see, although the print could be bigger. The tables could be more helpful. Fourth, contributions should be considered from health services researchers in pediatrics, internal medicine, and medical informatics, who have significantly contributed to advances in qualitative and quantitative health services research methods. This would include a discussion of issues in large database research, educational research techniques that affect patients, or a variety of other standard health services research techniques. However, some community-based interventions are discussed. Fifth, the authors only briefly discuss problems that they ran into during their research and common mistakes that were made. This would have been very valuable to other researchers and public policy workers. Finally, the link to applied clinical practice is not very strong, nor is the assertion of the authors that cost-savings can be achieved with these measures. Health services research and evidence-based practice are costly to conduct, but they assure accountability and allow effective programs to flourish while eliminating pet projects without evidence of benefit.
