Clinical effectiveness and cost-effectiveness of monitoring blood pressure of hypertensive employees at work.

In this randomized controlled trial, the value of using occupational health nurses (OHNs) to monitor the care of hypertensive employees at work was compared with regular care (RC) delivered in the community. One year after entry, the blood pressure level, medication history, compliance with treatment, and cost of hypertensive care of the participants were determined by independent evaluators. The reduction in diastolic blood pressure (DBP), the measure of effectiveness, was 10.5 +/- 1.1 mm Hg (mean +/- SEM) in the OHN group and 7.7 +/- 1.1 mm Hg in the RC group, and the proportion under good blood pressure control was 41.8% and 31.0% respectively. These between-group differences were not statistically significant. Although the employees in the OHN group were more medicated and had a lower treatment dropout rate, neither difference was statistically significant. In addition, the proportion of employees who were compliant with prescribed medication was virtually identical in both groups. The cost of the care received by employees in the OHN group of $ 404.14 for the year was substantially higher than that of $ 250.15 in the RC group with the difference principally related to the cost of visiting the OHNs and a significant difference in drug cost (p less than 0.006). The incremental cost-effectiveness (C/E) ratio of $ 53.67 per mm Hg DBP reduction per year for onsite blood pressure monitoring was higher than the base C/E ratio of $ 32.65 per mm Hg for regular care. Our findings indicate that monitoring the blood pressure of hypertensive employees at work is neither clinically effective nor cost-effective.(ABSTRACT TRUNCATED AT 250 WORDS)

The Cochrane Collaboration--advances and challenges in improving evidence-based decision making.

The Cochrane Collaboration is an international organization that aims to help people make well-informed decisions about health care by preparing, maintaining, and ensuring the accessibility of rigorous, systematic, and up-to-date reviews (and, where possible, meta-analyses) of the benefits and risks of health care interventions. This article describes the structure of the Cochrane Collaboration and the processes used to carry out the task of research transfer. The authors focus on recent achievements of the Collaboration, emphasize the current challenges and barriers the Collaboration is facing to live up to the expectations it has generated, and highlight the strategies that the organization is using to meet those challenges.

Evidence-based health care and the Cochrane Collaboration.

Evidence-based health care (EBHC) is a growing movement to integrate healthcare research with healthcare practice. A key element to EBHC is convenient access to relevant high-quality evidence. The Cochrane Collaboration is an international consortium of persons dedicated to producing and maintaining systematic reviews of healthcare practice and is an invaluable resource to the EBHC movement. This article will describe EBHC briefly and will highlight how the Cochrane Collaboration supports the EBHC perspective to create an efficient and effective healthcare system.

New approaches to addressing information needs in local public health agencies.

For local Public Health agencies to be fully responsive to community needs, staff must have ready access to up-to-date and accurate information. During the last several years, the Hamilton-Wentworth Department of Public Health Services (DPHS), a Teaching Health Unit affiliated with McMaster University, has been developing new information services including establishment of a specialized library on site; education sessions on the use of information stored in this library and in the Hamilton-Wentworth Health Library Network; innovative approaches to tailoring information services to staff needs including on-site access to on-line literature databases; and establishment of a group to retrieve and report community health data. In the initial three years of operation, surveys of Hamilton-Wentworth staff and a comparison health unit (Niagara) revealed that staff most frequently sought information from managers and support staff, as well as from personal books, articles and journals. Over half (57%) of the Hamilton-Wentworth staff reported use of the DPHS library, whereas 28% of Niagara Regional Health Unit staff reported use of their library. Other information services, for example, bibliographic indexes on population health, were less frequently used. Plans to increase their use are discussed.

Does a mailed continuing education program improve physician performance? Results of a randomized trial in antihypertensive care.

Evidence is sparse concerning the value of the "educational" materials that physicians receive in the mail. We conducted a randomized trial of a mailed continuing education program on hypertension for primary care physicians. Although formal pretesting documented that the program led to significant improvements in physician knowledge over the short term, the current study showed no lasting effect on physician knowledge (mean scores on an end-of-study questionnaire were 50% and 52% for study and control physicians, respectively) and no influence on performance in lowering the blood pressures of patients referred from screening (mean blood pressure drop for study patients, 12.2/10.4 mm Hg vs 13.0/10.6 mm Hg for control patients). The chance that we missed a difference in diastolic blood pressure as great as 3 mm Hg is less than 5%. Resources spent on instructional materials mailed to physicians may be wasted.
