We interpret the data in the study to suggest that periodontal therapy was associated with improved glycemic control in persons with type 2 DM.

It is important to evaluate the impact of clinical information systems on the quality and timeliness of documentation in the patient's record to ensure the systems are improving clinical care processes and providing value to the organization. An observational study was conducted to measure the accuracy and timeliness of vital signs data during three different stages of clinical documentation system implementation at a large academic medical center: (1) a paper medical record system, (2) a clinical documentation system with "computers on wheels" workstation outside the patient's room, and (3) a clinical documentation system with a Tablet PC affixed to the vital signs monitor. Patient observations (n = 270) were completed as patient care technicians made routine vital sign rounds. Equipping patient care technicians with a Tablet PC affixed to the vital signs monitor significantly improved (P < .05) the accuracy and timeliness of vital signs. In addition, a number of unintended consequences were discovered that proved helpful to the nurse managers and nursing informatics leadership team in providing support of the new system. Findings from this study emphasize the importance of ensuring that staff has the appropriate devices needed to effectively document patient care at the bedside.

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.
