“…5 The younger physicians in this study revealed that, they preferred getting information from the medical representatives or at conferences to reading journals. Medical representatives were likely to be their initial sources of information about new drugs, however, they regarded this channel less reliable compared to other sources.…”

“…Previous studies have documented varying preference for sources of drug information. [1][2][3][4][5] In a review article of several studies by Davies on information seeking behaviour of doctors has documented that the two most frequently used information sources were textbooks, followed by human contact (senior staff and peer contact). 7 The use of textbooks being commonest source of drug information was similar to our findings.…”

“…4 The majority of global efforts in providing drug information stem from the pharmaceutical industry with the aim of promoting specific drugs to the target doctors. 5 Researchers have attempted to describe the sources, importance and use of information about pharmaceuticals that can influence physicians' prescribing decisions. Fallacious and misleading claims are commonly found in the content presented by the pharmaceutical industry, which may pose a threat to the credibility of material/content as a useful source of accurate and reliable drug information.…”

Background: Drug use information is vital for ensuring rationale and safe drug therapy. Physician across the globe use different sources of drug information during their routine practice. Postgraduate residents are in their interim-phase of education, research and clinical exposure. They are exposed to vast array of authentic and non-authentic drug information due to technology advancements and interaction with peers and medical representatives. There exists paucity in literature on their preference and drug information pattern. Therefore, this study was conducted to find out their preference for drug information sources.Methods: The present study was prospective, observational, questionnaire-based survey. The study was conducted between March 2017 and April 2017. The study included postgraduate medical residents pursing speciality courses at a tertiary care teaching hospital in Navi-Mumbai. Data was compiled and analysed in Microsoft excel.Results: Majority postgraduate residents preferred Non-electronics source for drug information. Text books (84%) were commonly preferred followed by medical journals in Non-electronic sources while internet-websites (76%) followed by e-journals and e-books were preferred in electronic sources. Majority preferred non-electronic sources for drug pharmacology and adverse reactions while electronic was preferred for indication, interaction, cost and therapy guidelines. For information on new drugs, majority preferred journals (71%) and websites (64%). Lack of time, source knowledge and high cost were perceived limiting factors for drug information.Conclusions: Postgraduate residents have varied preferences for drug information resources. Internet websites poses a challenge for authentic drug information. Interventions in the form of continuous medical education are required to improve their information-seeking behaviours.

An Analysis of Guidance for Proper Usage Documents for Oncology Drugs in Japan

et al. 2012

View full text Add to dashboard Cite

Background: Pharmaceutical companies in Japan often provide a unique document called the Guidance for Proper Usage (GPU) to medical oncologists, in order to promote the proper use of an approved drug. Aim: The aim of the study was to examine the content of and current trends in the efficacy and safety data provided in GPU documents, in order to understand what pharmaceutical companies regard as important information for an oncologist to ensure proper usage of oncology drugs in Japan. Furthermore, this study analysed the influence of route of administration (oral or injection), drug class (cytotoxic or other), type of malignancy (haematological or solid malignancy) and the period of GPU publication (before and after April 2004) on the content of the GPU document. Materials and Methods: For the 103 oncology drugs approved for use in Japan, 59 GPU documents, covering 50 drugs, were distributed to medical oncologists and were compared by multivariate analysis over two consecutive time periods, from October 1994 to March 2004 and April 2004 to December 2010. For each document, we determined the total number of pages and the proportion of pages that provided drug and toxicity information and the results of registration trials, including postmarketing surveillance. Results: The median number of pages in the GPUs was 48 (range, 11-98). The proportion of pages providing toxicity information, drug information (e.g. warnings, contraindications, instructions, and directions for indications and usage, dosage and administration) and the results of registration trials were 30%, 26% and 11%, respectively. After April 2004, the publication of GPU documents doubled, and the proportion of pages discussing the results of registration trials significantly increased (p = 0.002). The proportions of pages discussing toxicity information and the results of registration trials in molecular-targeted drugs were significantly greater than those for other types of drugs (p < 0.001 and p = 0.008, respectively), while the proportion of pages discussing drug information was significantly lower (p = 0.001). Conclusion:The number and length of GPU publications distributed by pharmaceutical companies in Japan has increased since 2004. Significant changes in content have included a reduction in the amount of information about drug administration and an increase in information on the results of pharmaceutical company-sponsored registrational trials. A further study is warranted to evaluate how often oncologists actually access GPU documents and what type of information could be most useful in medical practice in Japan.
