![]() ![]() There is need to search several different databases. No one database can search all the medical literature. Education Resources Information Centre is a free online digital library of education research and information sponsored by the Institute of Education Sciences of the U.S. The choice of databases depends on the subject of interest and potential coverage by the different databases. Links to the full-text material are included in citations from PubMed Central and publisher web sites. More than 26 million citations from Medline, life science journals and online books are included in PubMed. PubMed ( ) is the largest available resource since 1996 however, a large number of sources now provide free access to literature in the biomedical field. Most of these are not freely available to the individual user. The various databases available for literature search include databases for original published articles in the journals and evidence-based databases for integrated information available as systematic reviews and abstracts. Dividing the questions into key components makes it easy and searchable. The patient or study population, intervention, comparison or control arm, primary outcome, timing of measurement of outcome (PICOT) is a well-known approach for framing a leading research question. Also the entire research process should conform to the ethical principles of research. One should also keep in mind the patient population under study and the resources available in a given set up. It should either confirm, refute or add information to already done research work. The idea should be interesting and relevant to clinical research. ![]() While formulating a research question, one should consider certain criteria, referred as ‘FINER’ (F-Feasible, I-Interesting, N-Novel, E-Ethical, R-Relevant) criteria. Patient-oriented questions can involve the effect of therapy or disease or examine advantage versus disadvantage for a group of patients.įor example, we want to evaluate the effect of a particular drug (e.g., dexmedetomidine) for procedural sedation in day care surgery patients. There can be general questions or patient-oriented questions that arise from clinical issues. It also helps in determining extraneous variables affecting the outcome and identifying faults or lacunae that could be avoided.įormulating a well-focused question is a critical step for facilitating good clinical research. Literature search is done to identify appropriate methodology, design of the study population sampled and sampling methods, methods of measuring concepts and techniques of analysis. The most important are formulating the research questions and planning your search. The literature search can be exhaustive and time-consuming, but there are some simple steps which can help you plan and manage the process. It should be apt containing necessary components, and raise a question that can be tested and investigated. ![]() It is one of the most important tools which aids to answer the research question. ![]() Once we have narrowed down the problem, seeking and analysing existing literature may further straighten out the research approach.Ī research hypothesis is a carefully created testimony of how you expect the research to proceed. It needs to be channelised by focussing on information yet to be explored. Research problem is typically a topic of interest and of some familiarity to the researcher. However, the main purpose of a thorough literature search is to formulate a research question by evaluating the available literature with an eye on gaps still amenable to further research. The reasons for conducting literature search are numerous that include drawing information for making evidence-based guidelines, a step in the research method and as part of academic assessment. Literature search is a systematic and well-organised search from the already published data to identify a breadth of good quality references on a specific topic. ![]()
