The American Recovery and Reinvestment Act identified secure patient-physician e-mail messaging as an objective of the meaningful use of electronic health records. In our study of 35,423 people with diabetes, hypertension, or both, the use of secure patient-physician e-mail within a two-month period was associated with a statistically significant improvement in effectiveness of care as measured by the Healthcare Effectiveness Data and Information Set (HEDIS). In addition, the use of e-mail was associated with an improvement of 2.0-6.5 percentage points in performance on other HEDIS measures such as glycemic (HbA1c), cholesterol, and blood pressure screening and control.

    • "Our findings are consistent with previous observational studies that have found an association between secure messaging and higher-quality diabetes care (6,7,9). Secure messaging also has been associated with better performance on process measures, including HbA1c, nephropathy, and retinopathy screening (7). Randomized controlled trials that have used secure messaging as part of diabetes case management have had mostly positive results (33–36). "

    ABSTRACT: OBJECTIVE To study differences in glycemic control and HbA1c testing associated with use of secure electronic patient-provider messaging. We hypothesized that messaging use would be associated with better glycemic control and a higher rate of adherence to HbA1c testing recommendations.RESEARCH DESIGN AND METHODS Retrospective observational study of secure messaging at Group Health, a large nonprofit health care system. Our analysis included adults with diabetes who had registered for access to a shared electronic medical record (SMR) between 2003 and 2006. We fit log-linear regression models, using generalized estimating equations, to estimate the adjusted rate ratio of meeting three indicators of glycemic control (HbA1c <7%, HbA1c <8%, and HbA1c >9%) and HbA1c testing adherence by level of previous messaging use. Multiple imputation and inverse probability weights were used to account for missing data.RESULTSDuring the study period, 6,301 adults with diabetes registered for access to the SMR. Of these individuals, 74% used messaging at least once during that time. Frequent use of messaging during the previous calendar quarter was associated with a higher rate of good glycemic control (HbA1c <7%: rate ratio, 1.26; 95% CI, 1.15-1.37) and a higher rate testing adherence (1.20 [1.15-1.25]).CONCLUSIONS Among SMR users, recent and frequent messaging use was associated with better glycemic control and a higher rate of HbA1c testing adherence. These results suggest that secure messaging may facilitate important processes of care and help some patients to achieve or maintain adequate glycemic control.

    ABSTRACT: There presently exists a large and growing body of embedded computer systems, computers that perform some controlling function in a larger system such as a communications system. These embedded systems are often developed by project teams that do not contain the expertise of the software engineer in the beginning phases. This approach was appropriate when the technical nature of the embedded system development had a relatively small software component. Now, however, the availability of cheap, powerful, general-purpose microprocessors has moved software into a more critical role in the system design process. As a result, the engineering that used to be conducted in a hardware design atmosphere is now being conducted in a software design and programming environment and the skills and experience of the software engineer are needed in the beginning phases of the design process. This paper discusses some of the differences between software engineering and other branches of engineering, presents an approach for integrating software and firmware into the overall system design process and suggests possible risk reduction measures to use during the development process.

    ABSTRACT: Multiple binary Frequency Shift Key (FSK/ Frequency Hop (FH) communications is an attractive alternative to conventional M-ary FSK/FH, providing increased transmission capacity with less susceptibility to interference. In non-coherent reception of independent binary Mark-Space signals, errors most often occur when only the complementary channel is jammed. Since conventional M-ary FSK/FH offers more opportunities for error than multiple binary FSK/FH, it is more prone to digital data error. Multiple binary FSK/FH provides the (same) high data rate of conventional M-ary signaling with the bit error rate of binary independent Mark-Space signaling.
