Improving blood pressure screening and control at an academic health system

A Curriculum on Advanced Topics in Hypertension for Internal Medicine Residents

OBJECTIVES

Hypertension (HTN) affects nearly half of US adults. Our multi-institutional survey revealed that Internal Medicine residents lack proficiency in advanced HTN topics. We developed a curriculum to address knowledge gaps in these topics and aimed to assess the effects of the curriculum on residents' confidence, desire for future training, and knowledge in advanced HTN topics.

METHODS

HTN experts taught four advanced topics in HTN: conducting a workup for secondary HTN, managing HTN in chronic kidney disease, managing HTN in patients who are or may become pregnant, and managing hypertensive urgency (severe asymptomatic HTN) in the outpatient setting. The setting of the curriculum was an ambulatory educational half-day, during which residents rotated through small-group sessions dedicated to each HTN topic. We developed pre-, immediate post-, and 8 weeks postcurriculum surveys assessing residents' confidence and desire for future training in the four topics (4-point Likert scales), and multiple-choice quizzes to assess changes in knowledge. We used repeated-measures analysis of variance to compare means between time points for surveys and quizzes.

RESULTS

A total of 112 Internal Medicine residents participated in the curriculum. The mean confidence scores for all four topics increased from 1.79 to 2.61 precurriculum to 2.90 to 3.45 immediately postcurriculum (all P < 0.001) and remained higher (2.53-3.18) than precurriculum at 8 weeks postcurriculum (all P < 0.02). The mean desire for future training scores decreased from 2.74 to 2.96 precurriculum to 2.06 to 2.36 immediately postcurriculum (all P < 0.001 except for managing HTN in patients who are or may become pregnant, which was P = 0.17) and remained lower (2.08-2.36) than precurriculum at 8 weeks postcurriculum (all P ≤ 0.003). The mean knowledge score increased from 48% precurriculum to 62% immediate postcurriculum (P < 0.001) and remained higher (55%) than precurriculum at 8 weeks postcurriculum (P = 0.015).

CONCLUSIONS

A curriculum on advanced HTN topics produced durable gains in confidence and knowledge and partially satisfied the desire for future learning among Internal Medicine residents.

Quality and Safety in Healthcare, Part XC: The A3 Approach and Lean in Healthcare

ABSTRACT

The A3 form is a structured way of solving problems using a detailed step-by-step methodology using the principles of the Plan-Do-Check-Act cycle. The A3 form supports efforts to organize the thinking of workers about new ways to improve. The form is used as a guide for many project teams to find answers, and then the team arrives at decisions through consensus. Sometimes process mapping, driver diagrams, and gap analysis are included in A3 problem solving. The A3 form is just one of numerous healthcare applications for the Toyota Production System and Lean.

Evaluation of an Academic Detailing Program to Improve Blood Pressure Measurement and Hypertension Treatment in Urban Community Health Centers

INTRODUCTION

Hypertension is estimated at a prevalence of 30 to 50% in the United States. Only 54% of patients with hypertension have their condition adequately controlled. This study aimed to use academic detailing (AD) to improve practice team knowledge and confidence in blood pressure (BP) management, specifically in low-income, underresourced patient populations.

METHODS

AD was developed for five practices that care for high percentages of Medicaid-eligible patients. A needs assessment was administered to each site's practice champion to determine high-yield AD sessions for their team. Presession and postsession evaluations were completed by practice team members.

RESULTS

Fifty providers and eight staff member participants completed evaluations over nine sessions for two AD topics at four practice sites. Statistical significance was found for several items within sessions including accurately choosing cuff sizes and identifying barriers to home BP monitoring.

DISCUSSION

AD is a potentially financially efficient model to improve knowledge and confidence in hypertension care at the practice level. Tailoring session content to specific needs of a practice site, along with an identified practice champion, facilitated implementation of the program. This replicable model is one way to deliver evidence-based information to those who serve Medicaid-eligible patients.

Clinician Knowledge and Practices Related to a Patient History of Hypertensive Disorders of Pregnancy

OBJECTIVE

To describe clinician screening practices for prior hypertensive disorders of pregnancy, knowledge of future risks associated with hypertensive disorders of pregnancy, barriers and facilitators to referrals for cardiovascular disease risk evaluation in women with prior hypertensive disorders of pregnancy, and variation by clinician- and practice-level characteristics.

METHODS

We used data from Fall DocStyles 2020, a cross-sectional, web-based panel survey of currently practicing U.S. clinicians. Of 2,231 primary care physicians, obstetrician-gynecologists (ob-gyns), nurse practitioners, and physician assistants invited to participate, 67.3% (n=1,502) completed the survey. We calculated the prevalence of screening, knowledge of future risks, and barriers and facilitators to referrals, and assessed differences by clinician type using χ2 tests. We evaluated associations between clinician- and practice-level characteristics and not screening using a multivariable log-binomial model.

RESULTS

Overall, 73.6% of clinicians screened patients for a history of hypertensive disorders of pregnancy; ob-gyns reported the highest rate of screening (94.8%). Overall, 24.8% of clinicians correctly identified all cardiovascular risks associated with hypertensive disorders of pregnancy listed in the survey. Lack of patient follow-through (51.5%) and patient refusal (33.6%) were the most frequently cited barriers to referral. More referral options (42.9%), patient education materials (36.2%), and professional guidelines (34.1%) were the most frequently cited resources needed to facilitate referrals. In the multivariable model, primary care physicians and nurse practitioners, as well as physician assistants, were more likely than ob-gyns to report not screening (adjusted prevalence ratio 5.54, 95% CI 3.24-9.50, and adjusted prevalence ratio 7.42, 95% CI 4.27-12.88, respectively). Clinicians seeing fewer than 80 patients per week (adjusted prevalence ratio 1.81, 95% CI 1.43-2.28) were more likely to not screen relative to those seeing 110 or more patients per week.

CONCLUSION

Three quarters of clinicians reported screening for a history of hypertensive disorders of pregnancy; however, only one out of four clinicians correctly identified all of the cardiovascular risks associated with hypertensive disorders of pregnancy listed in the survey.

Hospital Adoption of Electronic Decision Support Tools for Preeclampsia Management

BACKGROUND

Electronic health record (EHR)-based clinical decision support tools can improve the use of evidence-based clinical guidelines for preeclampsia management that can reduce maternal mortality and morbidity. No study has investigated the organizational capabilities that enable hospitals to use EHR-based decision support tools to manage preeclampsia.

OBJECTIVE

To examine the association of organizational capabilities and hospital adoption of EHR-based decision support tools for preeclampsia management.

METHODS

Cross-sectional analyses of hospitals providing obstetric care in 2017. In total, 739 hospitals responded to the 2017-2018 National Survey of Healthcare Organizations and Systems (NSHOS) and were linked to the 2017 American Hospital Association (AHA) Annual Survey Database and the Area Health Resources File (AHRF). A total of 425 hospitals providing obstetric care across 49 states were included in the analysis. The main outcome was whether a hospital adopted EHR-based clinical decision support tools for preeclampsia management. Hospital organizational capabilities assessed as predictors include EHR functions, adoption of evidence-based clinical treatments, use of quality improvement methods, and dissemination processes to share best patient care practices. Logistic regression estimated the association of hospital organizational capabilities and hospital adoption of EHR-based decision support tools to manage preeclampsia, controlling for hospital structural and patient sociodemographic characteristics.

RESULTS

Two-thirds of the hospitals (68%) adopted EHR-based decision support tools for preeclampsia, and slightly more than half (56%) of hospitals had a single EHR system. Multivariable regression results indicate that hospitals with a single EHR system were more likely to adopt EHR-based decision support tools for preeclampsia (17.4 percentage points; 95% CI, 1.9 to 33.0; P < .05) than hospitals with a mixture of EHR and paper-based systems. Compared with hospitals having multiple EHRs, on average, hospitals having a single EHR were also more likely to adopt the tools by 9.3 percentage points, but the difference was not statistically significant (95% CI, -1.3 to 19.9). Hospitals with more processes to aid dissemination of best patient care practices were also more likely to adopt EHR-based decision-support tools for preeclampsia (0.4 percentage points; 95% CI, 0.1 to 0.6, for every 1-unit increase in dissemination processes; P < .01).

CONCLUSION

Standardized EHRs and policies to disseminate evidence are foundational hospital capabilities that can help advance the use of EHR-based decision support tools for preeclampsia management in the approximately one-third of US hospitals that still do not use them.
