Background: Pharmacist-physician comanagement of hypertension has been shown to improve office blood pressures (BPs). We sought to describe the effect of such a model on 24-hour ambulatory BPs., Methods: We performed a prospective, cluster-randomized, controlled clinical trial, enrolling 179 patients with uncontrolled hypertension from 5 primary care clinics in Iowa City, Iowa. Patients were randomized by clinic to receive pharmacist-physician collaborative management of hypertension (intervention) or usual care (control) for a 9-month period. In the intervention group, pharmacists helped patients to identify barriers to BP control, counseled on lifestyle and dietary modifications, and adjusted antihypertensive therapy in collaboration with the patients' primary care providers. Patients were seen by pharmacists a minimum of every 2 months. Ambulatory BP was measured at baseline and at study end., Results: Baseline and end-of-study ambulatory BP profiles were evaluated for 175 patients. Mean (SD) ambulatory systolic BPs (SBPs), reported in millimeters of mercury, were reduced more in the intervention group than in the control group: daytime change in (Δ) SBP, 15.2 (11.5) vs 5.5 (13.5) (P < .001); nighttime ΔSBP, 12.2 (14.8) vs 3.4 (13.3) (P < .001); and 24-hour ΔSBP, 14.1 (11.3) vs 5.5 (12.5) (P < .001). More patients in the intervention group than in the control group had their BP controlled at the end of the study (75.0% vs 50.7%) (P < .001), as defined by overall 24-hour ambulatory BP monitoring., Conclusion: Pharmacist-physician collaborative management of hypertension achieved consistent and significantly greater reduction in 24-hour BP and a high rate of BP control.

Introduction: Physicians increasingly earn continuing medical education (CME) credits through on-line courses, but there have been few rigorous evaluations to determine their effects. The present study explores the feasibility of implementing standardized evaluation templates and tests them to evaluate 30 on-line CME courses., Methods: A time series design was used to compare the knowledge, attitudes, and reported changes in practice of physician participants who completed any of 30 on-line CME courses that were hosted on an academic CME Web site and a CME Web portal during the period from August 1, 2002, through March 31, 2003. Data were collected at baseline, at course completion, and 4 weeks later Paired t tests were used to compare the means of responses across time., Results: U.S. physicians completed 720 post-tests. Quality of content was the characteristic of most importance to participants; too little interaction was the largest source of dissatisfaction. Overall mean knowledge scores increased from 58.1% to 75.6% at post-test and then decreased to 68.2% at 4 weeks following the course. Effect sizes of increased knowledge immediately following the course were larger for case-based than for text-based courses. Nearly all physicians reported making changes in practice following course completion, although reported changes differed from expected changes., Conclusions: Increases in physician knowledge and knowledge retention were demonstrated following participation in on-line CME courses. The implementation of standardized evaluation tests proved to be feasible and allowed longitudinal evaluation analyses across CME providers and content areas.

Introduction: Much of the international community has an increased awareness of potential biologic, chemical, and nuclear threats and the need for physicians to rapidly acquire new knowledge and skills in order to protect the public's health. The present study evaluated the educational effectiveness of an online bioterrorism continuing medical education (CME) activity designed to address clinical issues involving suspected bioterrorism and reporting procedures in the United States. Methods: This was a retrospective survey of physicians who had completed an online CME activity on bioterrorism compared with a nonparticipant group who had completed at least 1 unrelated online CME course from the same medical school Web site and were matched on similar characteristics. An online survey instrument was developed to assess clinical and systems knowledge and confidence in recognition of illnesses associated with a potential bioterrorism attack. A power calculation indicated that a sample size of 100 (50 in each group) would achieve 90% power to detect a 10% to 15% difference in test scores between the two groups. Results: Compared with nonparticipant physicians, participants correctly diagnosed anthrax (p = 0.01) and viral exanthem (p = 0.01), but not smallpox, more frequently than nonparticipants. Participants knew more frequently than nonparticipants who to contact regarding a potential bioterrorism event (p = 0.03) Participants were more confident than nonparticipants about finding information to guide diagnoses of patients with biologic exposure (p = 0.01), chemical exposure (p = 0.02), and radiation exposure (p = 0.04). Discussion: An online bioterrorism course shows promise as an educational intervention in preparing physicians to better diagnose emerging rare infections, including those that may be associated with a bioterrorist event, in increasing confidence in diagnosing these infections, and in reporting of such infections for practicing physicians.

Introduction: As they care for patients, physicians raise questions, but they pursue only a portion of them. Without the best information and evidence, care and patient safety may be compromised. Understanding when and why problems prompt physicians to look for information and integrate results into their knowledge base is critical and shapes one part of reflection about care. This study explores the role of the Internet in gathering medical information as one step in that reflective practice, the barriers to its use, and changes in utilization over time. Methods: A questionnaire with 18 items adapted from previous studies was sent by facsimile to a randomly selected sample of U.S. physicians in all specialties and active in practice. Results: Specific patient problems and latest research in a specific topic most often prompt physicians to search on the Internet. Younger physicians and female physicians were most likely to seek information on a specific patient problem. Only 9% of all respondents (n = 2, 500) searched for information during a patient encounter. When unsure about diagnostic and management issues for a complex case, 41.3% chose to consult with a colleague or read from a text (22.8%). Searching most often occurred at home after work (38.2%) or during breaks in the day (35.7%). Most (68.7%) found the information they were looking for more than 51% of the time. Searching was facilitated by knowing preferred sites and access in the clinical setting. The greatest barriers to answering clinical questions included a lack of specific information and too much information to scan. Discussion: Although physicians are increasingly successful and confident in their Internet searching to answer questions raised in patient care, few choose to seek medical information during a patient encounter. Internet information access may facilitate overall reflection on practice; physicians do not yet use this access in a just-in-time manner for immediately solving difficult patient problems but instead continue to rely on consultation with colleagues. Professional association Web sites and point-of-care databases are helpful. From physicians' use of the Internet, professionals in continuing medical education must learn which search engines and sites are trusted and preferred.
