Over the last two decades, changes in technology have allowed academic medical center libraries to bring the world of biomedical information to the physician's computer desktop. Because digital libraries have grown so rapidly and in so many ways, some clinicians may be uncertain about the services and resources that are available to them. This article explains how clinical faculty can best utilize their library to support their research and patient care. It addresses some of the most common myths about the "new" medical library, and it highlights innovations in library resources and services that can help physicians to better access, use and manage medical information.

BACKGROUND: To practice Evidence-Based Medicine (EBM), physicians must quickly retrieve evidence to inform medical decisions. Internal Medicine (IM) residents receive little formal education in electronic database searching, and have identified poor searching skills as a barrier to practicing EBM. OBJECTIVE: To design and implement a database searching tutorial for IM residents on inpatient rotations and to evaluate its impact on residents' skill and comfort searching MEDLINE and filtered EBM resources. DESIGN: Randomized controlled trial. Residents randomized to the searching tutorial met for up to 6 1-hour small group sessions to search for answers to questions about current hospitalized patients. PARTICIPANTS: Second- and 3rd-year IM residents. MEASUREMENTS: Residents in both groups completed an Objective Structured Searching Evaluation (OSSE), searching for primary evidence to answer 5 clinical questions. OSSE outcomes were the number of successful searches, search times, and techniques utilized. Participants also completed self-assessment surveys measuring frequency and comfort using EBM databases. RESULTS: During the OSSE, residents who participated in the intervention utilized more searching techniques overall (p < .01) and used PubMed's Clinical Queries more often (p < .001) than control residents. Searching "success" and time per completed search did not differ between groups. Compared with controls, intervention residents reported greater comfort using MEDLINE (p < .05) and the Cochrane Library (p < .05) on post-intervention surveys. The groups did not differ in comfort using ACP Journal Club, or in self-reported frequency of use of any databases. CONCLUSIONS: An inpatient EBM searching tutorial improved searching techniques of IM residents and resulted in increased comfort with MEDLINE and the Cochrane Library, but did not impact overall searching success.

Thyroid hormone and breast carcinoma.

BACKGROUND: To investigate the role of primary hypothyroidism (HYPT) on breast carcinogenesis, the authors evaluated 1) the association between HYPT and a diagnosis of invasive breast carcinoma and 2) the clinicopathologic characteristics of breast carcinoma in patients with HYPT. METHODS: For this retrospective chart review study, 1136 women with primary breast carcinoma (PBC) were identified from the authors' departmental data base. These women (cases) were frequency-matched for age (+/- 5 years) and ethnicity with 1088 healthy participants (controls) who attended a breast carcinona screening clinic. Women with HYPT who were receiving thyroid-replacement therapy before they were diagnosed with breast carcinoma or before the screening visit were identified. RESULTS: The mean ages of cases and controls (51.6 years vs. 51.0 years, respectively; P = 0.30) and their menopausal status (65.4% premenopausal vs. 62% postmenopausal; P = 0.10) were comparable. Two hundred forty-two women in the case group (10.9%) with HYPT were identified. The prevalence of this condition was significantly greater the control group compared with the case group (14.9% vs. 7.0%, respectively; P < 0.001). PBC patients were 57% less likely to have HYPT compared with their healthy counterparts (odds ratio, 0.43l 95% confidence interval, 0.33-0.57). Seventy-eight white patients with PBC had HYPT and, compared with women who were euthyroid, they were older at the time of diagnosis (58.8 years vs. 51.1 years; P < 0.001), were more likely to have localized disease (95.0% vs. 85.9% clinical T1 or T2 disease, respectively; P = 0.025), and were more likely to have no pathologic lymph node involvement (62.8% vs. 54.4%; P = 0.15). CONCLUSIONS: Primary HYPT was associated with a reduced risk for PBC and a more indolent invasive disease. These data suggest a possible biologic role for thyroid hormone in the etiology of breast carcinoma and indicate areas of research for the prevention and treatment of breast carcinoma. Cancer 2005.
