Visual Analytics Dashboard Promises to Improve Hypertension Guideline Implementation.

BACKGROUND: Primary care management of hypertension under new guidelines incorporates assessment of cardiovascular disease risk and commonly requires review of electronic health record (EHR) data. Visual analytics can streamline the review of complex data and may lessen the burden clinicians face using the EHR. This study sought to assess the utility of a visual analytics dashboard in addition to EHR in managing hypertension in a primary care setting. METHODS: Primary care physicians within an urban, academic internal medicine clinic were tasked with performing 2 simulated patient encounters for hypertension management: the first using standard EHR, and the second using EHR paired with a visual dashboard. The dashboard included graphical blood pressure trends with guideline-directed targets, calculated atherosclerotic cardiovascular disease risk score, and relevant medications. Guideline-appropriate antihypertensive prescribing, correct target blood pressure goal, and total encounter time were assessed. RESULTS: We evaluated 70 case simulations. Use of the dashboard with the EHR compared with use of the EHR alone was associated with greater adherence to prescribing guidelines (95% vs. 62%, P < 0.001) and more correct identification of blood pressure target (95% vs. 57%, P < 0.01). Total encounter time fell an average of 121 seconds (95% confidence interval 69-157 seconds, P < 0.001) in encounters that used the dashboard combined with the EHR. CONCLUSIONS: The integration of a hypertension-specific visual analytics dashboard with EHR demonstrates the potential to reduce time and improve hypertension guideline implementation. Further widespread testing in clinical practice is warranted.

Intra-Amniotic Administration of HMGB1 Induces Spontaneous Preterm Labor and Birth.

PROBLEM: Sterile intra-amniotic inflammation is associated with spontaneous preterm labor. Alarmins are proposed to mediate this inflammatory process. The aim of this study was to determine whether intra-amniotic administration of an alarmin, HMGB1, could induce preterm labor/birth. METHOD OF STUDY: Pregnant B6 mice were intra-amniotically or intraperitoneally injected with HMGB1 or PBS (control). Following injection, the gestational age and the rates of preterm birth and pup mortality were recorded. RESULTS: Intra-amniotic injection of HMGB1 led to preterm labor/birth [HMGB1 57% (4/7) versus PBS 0% (0/6); P = 0.049) and a high rate of pup mortality at week 1 [HMGB1 60.9 ± 11.7% (25/41) versus PBS 28.9 ± 12.6% (11/38); P = 0.001). Intraperitoneal injection of HMGB1 did not induce preterm labor/birth. CONCLUSION: Intra-amniotic administration of HMGB1 induces preterm labor/birth.
