Many of the ideas would strike the outsider as silly or worse. For instance, in health services areas, there is great interest in the problem of back injuries among nursing staff. It's not necessarily the thing that comes first to mind when we think about the health care field. But if you reflect on it for a minute longer, it should be obvious that nurses and nursing staff do an awful lot of lifting in performing their jobs. Even minor injuries can result in increased absenteeism.
Major ones can result in lost jobs and expensive medical bills.
The nursing industry figures that this is a problem that costs tens of millions of dollars annually in increased health care. And, the health care industry has developed a number of approaches, many of them educational, to try to reduce the scope and cost of the problem. So, even though it might seem silly at first, many of these practical problems that arise in practice can lead to extensive research efforts. Another source for research ideas is the literature in your specific field . Certainly, many researchers get ideas for research by reading the literature and thinking of ways to extend or refine previous research.
