“…It is unknown whether using a longer (or, indeed, shorter) cascade would significantly alter the search results or the answers provided. It has been suggested that a pragmatic approach to searching is eVective, 21 but we are unaware of any research on the relative benefits of diVerent approaches in the context of providing evidence-based information for clinicians. It is possible that a flexible approach could be adopted in which users of informaticist services could determine their preferred approach in advance.…”

Results-All 100 clinicians in two primary care groups were approached. Thirty four agreed to participate, of whom 22 asked 60 questions over 10 months. Participants were highly satisfied with the summaries they received. For one third of questions the clinicians stated they would change practice in the index patient, and for 55% the participants stated they would change practice in other patients. Answering questions thoroughly was time consuming (median 130 minutes). The median turnaround time was 9 days; 82% of questions were answered within the timeframe specified by the questioner. Without the informaticist, one third of questions would not have been pursued. Conclusion-The clinical informaticist service increased access to evidence for busy clinicians. Satisfaction was high among users and clinicians stated that changes in practice would occur. However, uptake of the service was lower than expected (22% of those oVered the service). Further research is needed into how this method of increasing access to evidence compares with other strategies, and whether it results in improved health outcomes for patients.

“…No single database can cover all the medical literature required for a systematic review, although some are considered to be a core element of any healthcare search strategy, such as MEDLINE [ 15 ], Embase [ 16 ], and the Cochrane Library [ 17 ]. Consequently, healthcare information professionals may consult these sources along with a number of other, more specialized databases to fit the precise scope area [ 18 ].…”

BackgroundHealthcare information professionals play a key role in closing the knowledge gap between medical research and clinical practice. Their work involves meticulous searching of literature databases using complex search strategies that can consist of hundreds of keywords, operators, and ontology terms. This process is prone to error and can lead to inefficiency and bias if performed incorrectly.ObjectiveThe aim of this study was to investigate the search behavior of healthcare information professionals, uncovering their needs, goals, and requirements for information retrieval systems.MethodsA survey was distributed to healthcare information professionals via professional association email discussion lists. It investigated the search tasks they undertake, their techniques for search strategy formulation, their approaches to evaluating search results, and their preferred functionality for searching library-style databases. The popular literature search system PubMed was then evaluated to determine the extent to which their needs were met.ResultsThe 107 respondents indicated that their information retrieval process relied on the use of complex, repeatable, and transparent search strategies. On average it took 60 minutes to formulate a search strategy, with a search task taking 4 hours and consisting of 15 strategy lines. Respondents reviewed a median of 175 results per search task, far more than they would ideally like (100). The most desired features of a search system were merging search queries and combining search results.ConclusionsHealthcare information professionals routinely address some of the most challenging information retrieval problems of any profession. However, their needs are not fully supported by current literature search systems and there is demand for improved functionality, in particular regarding the development and management of search strategies.

“…But, although most clinicians support the notion of evidence based health care in principle and wish to use evidence based information generated by others, only a tiny fraction seek to acquire all the requisite skills themselves 1. A study in British general practice found that the commonest reason cited for not practising evidence based health care was lack of time, followed by “personal and organisational inertia.”1 Acknowledging that this resonated with their own experience, Guyatt and colleagues recently formally withdrew their call that all practitioners should become fully competent in evidence based medicine,2 and others have called for the development of pragmatic, as well as systematic, approaches to supporting best practice 3…”

Objectives To describe and evaluate two different models of a clinical informaticist service. Design A case study approach, using various qualitative methods to illuminate the complexity of the project groups' experiences. Setting UK primary health care. Interventions Two informaticist projects to provide evidence based answers to questions arising in clinical practice and thereby support high quality clinical decision making by practitioners.
