PURPOSE Evidence shows the value of home blood pressure (BP) monitoring in hypertension management. Questions exist about how to effectively incorporate these readings into BP follow-up visits. We developed and implemented a tool that combines clinical and home BP readings into an electronic health record (EHR)-integrated visualization tool. We examined how this tool was used during primary care visits and its effect on physician-patient communication and decision making about hypertension management, comparing it with home BP readings on paper. METHODS We video recorded the hypertension follow-up visits of 73 patients with 15 primary care physicians between July 2018 and April 2019. During visits, physicians reviewed home BP readings with patients, either directly from paper or as entered into the EHR visualization tool. We used conversation analysis to analyze the recordings. RESULTS Home BP readings were viewed on paper for 26 patients and in the visualization tool for 47 patients. Access to home BP readings during hypertension management visits, regardless of viewing mode, positioned the physician and patient to assess BP management and make decisions about treatment modification, if needed. Length of BP discussion with the visualization tool was similar to or shorter than that with paper. Advantages of the visualization tool included ease of use, and enhanced and faster sense making and decision making. Successful use of the tool required patients' ability to obtain their BP readings and enter them into the EHR via a portal, and an examination room configuration that allowed for screen sharing. CONCLUSIONS Reviewing home BP readings using a visualization tool is feasible and enhances sense making and patient engagement in decision making. Practices and their patients need appropriate infrastructure to realize these benefits.

Context: Hispanics are at increased risk for diabetes, while rural residents have historically had decreased access to care. Purpose: To determine whether living in a rural area and being Hispanic confers special risks for diagnosis and control of diabetes. Methods: We analyzed the Third National Health and Nutrition Examination Survey (1988-1994). Hispanics and non-Hispanic white adults were classified according to rural/urban residence to create 4 ethnicity-residence groups. Investigated outcomes were previously diagnosed and undiagnosed diabetes. Among those with diagnosed diabetes, we investigated control of glucose, hypertension, and lipids. Findings: The prevalence of diagnosed diabetes was greatest for rural residents, especially for rural Hispanics (8.2%) versus that for urban whites (4.6%), rural whites (6.5%), or urban Hispanics (4.5%), (P less than 0.01). However, urban Hispanics were most likely to have undiagnosed diabetes at 3.7%, versus 2.3% of rural whites, 2.8% of urban whites, and 2.7% of rural Hispanics (P = 0.04). Among people with diagnosed diabetes, there was no difference in glycemic control between the 4 groups. Rural Hispanics with diagnosed diabetes had the greatest prevalence of elevated systolic blood pressure at 45%, compared to 37% of urban whites, 29% of rural whites, 28% of urban Hispanics (P = 0.01). In regression models controlling for potential confounders, there were no differences among urban and rural whites and Hispanics in the likelihood of undiagnosed diabetes or in glycemic control for those with diagnosed diabetes. Conclusions: Initiatives that target Hispanic health, and especially diabetes, should acknowledge rural/urban Hispanic health differences.

Objectives. We examined the relationship between continuity of care and diabetes control. Methods. We analyzed data on 1400 adults with diabetes who took part in the Third National Health and Nutrition Examination Survey. We examined the relationship of continuity of care with glycemic, blood pressure, and lipid control. Results. Continuity of care was associated with both acceptable and optimal levels of glycemic control. Continuity was not associated with blood pressure or lipid control. There was no difference between having a usual site but no usual provider and having a usual provider in any of the investigated outcomes. Conclusions. Continuity of care is associated with better glycemic control among people with diabetes. Our results do not support a benefit of having a usual provider above having a usual site of care.
