“…Some GPs do not prescribe new drugs until esteemed specialists use them [16]. In contrast to the huge impact of the drug industry's promotion, GPs often deny that this affects their prescribing [18,19] and feel they can distinguish between reliable and misleading information from the pharmaceutical companies [19]. Hence, efforts should be concentrated on informing the GPs of how the pharmaceutical industry may influence their prescribing.…”

“…It is also likely that the setting in which physicians work as well as inspiration from colleagues influence the GP's decision to prescribe a new drug [10,11,17,27]. In addition, specialists' prescribing patterns are likely to influence GPs' adoption of new drugs [22,24,28]. Finally, threats of formal complaints by patients or their relatives may also influence the outcome of which drug to prescribe [29][30][31].…”

AimTo test the hypothesis that general practitioners (GPs) with high prescribing levels of certain drugs will adopt new drugs belonging to the same therapeutic group faster than those with low prescribing levels. MethodsThe adoption of four new drugs: esomeprazol, selective cyclo-oxygenase-2 inhibitors, new triptans, and angiotensin-II receptor blockers were analysed using populationbased prescription data. We used the preference proportion (prescriptions for new rather than older alternatives for the same indication) to measure GPs' adoption rate. Annual prescribing volume and prevalence were used to measure previous prescribing of older drug alternatives. We modelled the preference proportion using multiple linear regression analysis and the prescribing of older drugs as independent variables. We controlled for the GPs' general prescribing level and weighted for practice size. In the first three analyses, we dichotomized data using the median, lower and upper quartile as cut-off point. Next, we grouped data into quartiles and finally, we used continuous data. ResultsFor esomeprazol and new triptans there was a higher preference for new drugs among 'high prescribers', but only when this term was defined as the upper quarter and the upper half of previous prescribing levels, respectively (mean difference in preference proportion: 10.2% (99% confidence interval = 1.3%, 19.1%) and 8.2% (0.2%, 16.2%)). For the remaining two drug classes the associations were weak and almost all statistically nonsignificant. ConclusionThere is no consistent association between GPs' level of drug prescribing and their adoption of new drugs of the same therapeutic group.

“…Using deductive content analysis a more detailed study was then carried out on the findings from five representative reports of physicians' information behaviour (Green and Ruff, 2005;Hughes et al, 2010;Lacey Bryant, 2004;Prosser et al, 2003;Reddy and Jansen, 2008). These reports were selected because: a) all involved direct interviews with or observation of physicians b) each report is detailed and includes quotations from the physicians or vignettes describing activities observed during the study c) together they cover both primary and secondary care physicians (general practitioners and hospital doctors) d) together they cover a number of different aspects of information behaviour:…”

This is the accepted version of the paper.This version of the publication may differ from the final published version. Design/methodology/approach -To investigate the model's application to information users, the findings from published literature on physicians' information behaviour were studied. To investigate its application to information providers, interviews were carried out with staff working for the National Institute for Health and Care Excellence and with employees of pharmaceutical companies. The findings were examined using deductive content analysis. Permanent repository linkFindings -The findings endorse the validity of the model, with minor modifications. The ISCM provides practical insights into the behaviour of both users and providers of information and the factors that influence them. It can be used to identify ways in which information behaviour may be positively modified in both finding and communicating healthcare information.Originality/value -This research demonstrates the practical value of a new model of information behaviour which was developed using insights from earlier models. In doing so it answers criticisms that research in library and information science often fails to build on previous research and that it has little practical usefulness.
