The effect of periodontal treatment on glycemic control in patients with type 2 diabetes mellitus.

BACKGROUND, AIMS: This study was designed to explore the effect of periodontal therapy on glycemic control in persons with type 2 diabetes mellitus (DM). METHODS: 36 patients with type 2 DM (treatment group) received therapy for adult periodontitis during an 18-month period. A 36-person control group was randomly selected from the same population of persons with type 2 DM who did not receive periodontal treatment. RESULTS: These groups were well matched for most of the parameters investigated. During the nine-month observation period, there was a 6.7% improvement in glycemic control in the control group when compared to a 17.1% improvement in the treatment group, a statistically significant difference. Several parameters that could confound or moderate this glycemic control were explored. These included the treatment of non-dental infections, weight and medication changes. No moderating effect was associated with any of these variables. However, there were too few subjects in the study to have the statistical power necessary to assess these possible moderators of glycemic control. CONCLUSIONS: We interpret the data in the study to suggest that periodontal therapy was associated with improved glycemic control in persons with type 2 DM.

Impact of an electronic medical record system on community-based primary care practices.

BACKGROUND: Although primary care physicians are increasingly interested in adopting electronic medical record (EMR) systems, few use such systems in practice. This study explores the organizational impact of an EMR system on community-based practices that have overcome the initial barriers and are experienced EMR users. METHODS: Five primary care practices that are members of a national research network participated in this study. Using qualitative methods, including semistructured interviews and observations, we assessed the impact of an EMR system on the work lives of various user groups. RESULTS: Physicians and staff indicated that the EMR system has changed not only how they manage patient records but also how they communicate with each other, provide patient care services, and perform job responsibilities. The EMR is also perceived by its users to have an impact on practice costs. Although in most practices physicians and staff were unaware of actual expenses and cost savings associated with the EMR, those in practices that have eliminated duplicate paper-based systems believe they have realized cost savings. CONCLUSIONS: Several important themes emerged. The organizational context in which the system is implemented is important. Effective leadership, the presence of a system champion, availability of technical training and support, and adequate resources are essential elements to the success of the EMR.

Clinics go electronic: two stories from the field.

We hear a lot about computerized record system implementations in hospitals, but other settings are making the transition as well. How does the move to an electronic record system affect day-to-day operations in clinics? Our writers tell how a student health center and a family clinic did it--and how they're working now.

Medication cost information in a computer-based patient record system. Impact on prescribing in a family medicine clinical practice.

BACKGROUND: Medications account for 8% of national health care expenditures, and prescription drugs are a focus of cost containment measures. Physicians have limited knowledge about drug costs, and no method of providing this information has demonstrated sustained cost reductions. OBJECTIVE: To determine the impact of cost information in a computer-based patient record system on prescribing by family physicians. METHODS: A yearlong, controlled clinical trial was conducted at the Family Medicine Center, Medical University of South Carolina, Charleston, a group practice staffed by attending physicians and residents. Prescription cost information was included in the computer-based patient record system used at the center. During a 6-month period, cost information was not displayed; during the subsequent 6-month intervention period, costs were displayed at the time of prescribing. An intention-to-treat analysis was used to compare prescription costs between the control and intervention periods for all medications prescribed, and stratified analyses for several medication and physician factors were performed. RESULTS: A total of 22,883 prescriptions were written during the 1-year study period. The mean +/- SD cost per prescription in the control period was $21.83 +/- $27.00 (range, $0.01-$510.00), and in the intervention period was $22.03 +/- $28.12 (range, $0.01-$435.96) (P = .61, Student t test). Increases in mean prescription cost and proportion of total costs were identified in 4 medication classes: antibiotics, cardiovascular agents, headache therapies, and antithrombotic agents. Decreases in mean prescription cost and proportion of total costs were identified in 5 medication classes: nonsteroidal anti-inflammatory drugs, histamine type 2-receptor antagonists and proton pump inhibitors, ophthalmic preparations, vaginal preparations, and otic preparations. CONCLUSIONS: In this setting, the provision of real-time computerized drug cost information did not affect overall prescription drug costs to patients, although differences in individual medication classes were observed. The negative results of this study may reflect confounding due to the use of historical controls, suboptimal timing of the intervention in the prescribing process, susceptibility bias at the study site, or the insensitivity of prescribing habits to cost information.

The outcomes movement and the role of health information managers.

The resounding demand that health care organizations demonstrate their effectiveness in providing quality patient services is being voiced by federal and state governments, managed care organizations, the Joint Commission on Accreditation of Healthcare Organizations, and businesses and insurers purchasing and paying for health care services. The outcomes movement arose in response to these demands and is intended to provide a means for increasing medical effectiveness and reducing costs. The article presents an overview of the outcomes movement and discusses the use of outcomes data, the challenges and issues associated with outcomes assessment, and how health information managers can play a role in facilitating outcomes assessment. It suggests areas of professional development that health information managers may wish to explore.

An interdisciplinary educational approach to assessing the health care and health educational needs of the elderly in a South Carolina community.

This article describes work from an allied health project grant that resulted in an interdisciplinary geriatric educational experience for health professions faculty and students (health information administration, occupational therapy, physical therapy, and health professions education) at an academic health sciences center. The educational experience centered on the process of designing, administering, and analyzing the results of a comprehensive needs assessment for clients attending a senior citizen center. This process enabled faculty and students to integrate education, service, and research activities into their curricula, and to work as an interdisciplinary team in assessing the health care needs of elderly adults in the community.

Developing a health information network within an integrated delivery system: a case study.

Changes in the health care environment, such as the growth of integrated delivery systems and the proliferation of managed care, are having a profound impact on the way in which health care organizations manage both clinical and financial information. Health information networks (HINs) are emerging to support the goals and internal needs of integrated delivery systems. In this environment, health care managers must assume a leadership role in planning for the development of HINs. The article provides an overview of the principal issues that should be addressed in an organization's information systems plan when a HIN is being developed and includes a case study that illustrates the key points discussed.

The impact of technology on the confidentiality of health information.

The article discusses the changes in health care delivery and the advances in computer technology that have resulted in benefits to patient care but also have raised concerns for protecting the confidentiality of health information. Numerous techniques for safeguarding computer information are also presented.
