Key result
Hypertension Patient Interview Guide provides a blank survey to gather patient preferences for BP management.
Why the study?
Patient-facing clinical decision support tools may help patients adhere to evidence-based high blood pressure care, but customization is required to best engage patients in controlling hypertension.
How do different designs of patient-facing clinical decision support tools affect perceived trustworthiness and intended actions in adults with hypertension?
How do different designs of patient-facing clinical decision support tools affect perceived trustworthiness and intended actions in adults with hypertension?
Patients with hypertension perceive detailed clinical decision support displays as more trustworthy, though this does not necessarily translate to differences in intended actions.
Detailed decision support displays may boost perceived trustworthiness in hypertension; this cross-sectional finding leaves open effects on actions and requires prospective validation.
BACKGROUND: High blood pressure (HBP) affects nearly half of adults in the United States and is a major factor in heart attacks, strokes, kidney disease, and other morbidities. To reduce risk, guidelines for HBP contain more than 70 recommendations, including many related to patient behaviors, such as home monitoring and lifestyle changes. Thus, the patient's role in controlling HBP is crucial. Patient-facing clinical decision support (CDS) tools may help patients adhere to evidence-based care, but customization is required. OBJECTIVE: Our objective was to understand how to adapt CDS to best engage patients in controlling HBP. METHODS: We conducted a mixed methods study with two phases: (1) survey-guided interviews with a limited cohort and (2) a nationwide web-based survey. Participation in each phase was limited to adults aged between 18 and 85 years who had been diagnosed with hypertension. The survey included general questions that assessed goal setting, treatment priorities, medication load, comorbid conditions, satisfaction with blood pressure (BP) management, and attitudes toward CDS, and also a series of questions regarding A/B preferences using paired information displays to assess perceived trustworthiness of potential CDS user interface options. RESULTS: We conducted 17 survey-guided interviews to gather patient needs from CDS, then analyzed results and created a second survey of 519 adults with clinically diagnosed HBP. A large majority of participants reported that BP control was a high priority (83%), had monitored BP at home (82%), and felt comfortable using technology (88%). Survey respondents found displays with more detailed recommendations more trustworthy (56%-77% of them preferred simpler displays), especially when incorporating social trust and priorities from providers and patients like them, but had no differences in action taken. CONCLUSIONS: Respondents to the survey felt that CDS capabilities could help them with HBP control. The more detailed design options for BP display and recommendations messaging were considered the most trustworthy yet did not differentiate perceived actions.
