Interpreting and acting upon home blood pressure readings: a qualitative study

Patient Experiences With Blood Pressure Measurement Methods for Hypertension Diagnosis: Qualitative Findings From the BP-CHECK Study

BACKGROUND

Out-of-office blood pressure (BP) measurement is recommended when making a new hypertension diagnosis. In practice, however, hypertension is primarily diagnosed using clinic BP. The study objective was to understand patient attitudes about accuracy and patient-centeredness regarding hypertension diagnostic methods.

METHODS

Qualitative study within a randomized controlled diagnostic study conducted between May 2017 and March 2019 comparing the accuracy and acceptability of BP measurement methods among patients in an integrated healthcare delivery system. All participants completed 24-hour ambulatory blood pressure monitoring (ABPM), plus either clinic BP, home BP monitoring (HBPM), or kiosk BP diagnostic testing. Qualitative interviewees (aged 31-76 years, n = 35) were recruited from the main study.

RESULTS

Participants who completed HBPM found it to be comfortable and low burden, and believed it produced accurate results. Participants in the clinic arm described clinic measurements as inconvenient. Participants in the kiosk arm overall did not favor kiosks due to concerns about accuracy and privacy. Participants described ABPM as the most accurate method due to repeated measurements over the 24-hour period in real-world contexts, but many found it uncomfortable and disruptive. Participants also noted methods that involved repeated measures such as HBPM and ABPM particularly influenced their understanding of whether or not they had hypertension.

CONCLUSIONS

Hypertension diagnostic methods that include more BP measurements help patients gain a deeper understanding of BP variability and the lower reliability of infrequent measurements in the clinic. These findings warrant implementing strategies to enhance out-of-office BP diagnostic testing in primary care.

Digital Self-monitoring of Multiple Sclerosis: Interview Study With Dutch Health Care Providers on the Expected New Configuration of Roles and Responsibilities

Background

Digital self-monitoring allows patients to produce and share personal health data collected at home. This creates a novel situation in which health care providers and patients must engage in a reconfiguration of roles and responsibilities. Although existing research pays considerable attention to the perceptions of patients regarding digital self-monitoring, less attention has been paid to the needs, wishes, and concerns of health care providers. As several companies and public institutions are developing and testing digital self-monitoring at the time of writing, it is timely and relevant to explore how health care providers envision using these technologies in their daily work practices. Our findings can be considered in decision-making processes concerning the further development and implementation of digital self-monitoring.

Objective

This study aims to explore how health care providers envisage using smartphone apps for digital self-monitoring of multiple sclerosis (MS) in their daily work practices, with a particular focus on physician-patient communication and on how health care providers respond to self-monitoring data and delegate tasks and responsibilities to patients.

Methods

We conducted semistructured in-depth interviews with 14 MS health care providers: 4 neurologists, 7 MS specialist nurses, and 3 rehabilitation professionals. They are affiliated with 3 different hospitals in the Netherlands that will participate in a pilot study to assess the efficiency and effectiveness of a specific smartphone app for self-monitoring.

Results

The interviewed health care providers seemed willing to use these smartphone apps and valued the quantitative data they produce that can complement the narratives that patients provide during medical appointments. The health care providers primarily want to use digital self-monitoring via prescription, meaning that they want a standardized smartphone app and want to act as its gatekeepers. Furthermore, they envisioned delegating particular tasks and responsibilities to patients via digital self-monitoring, such as sharing data with the health care providers or acting on the data, if necessary. The health care providers expected patients to become more proactive in the management of their disease. However, they also acknowledged that not all patients are willing or able to use digital self-monitoring apps and were concerned about the potential psychological and emotional burden on patients caused by this technology.

Conclusions

Our findings show that health care providers envisage a particular type of patient empowerment and personalized health care in which tensions arise between health care providers acting as gatekeepers and patient autonomy, between patient empowerment and patient disempowerment, and between the weight given to quantitative objective data and that given to patients’ subjective experiences. In future research, it would be very interesting to investigate the actual experiences of health care providers with regard to digital self-monitoring to ascertain how the tensions mentioned in this paper play out in practice.

Is self-management a burden? What are the experiences of women self-managing chronic conditions during pregnancy? A systematic review

OBJECTIVE

This systematic review examines the qualitative literature on women's experiences of self-managing chronic conditions in pregnancy.

DESIGN

Systematic review of qualitative literature. Searches were performed in PubMed and CINAHL from inception to February 2021. Critical interpretive synthesis informed the coding framework and the analysis of the data. The Burden of Treatment theory emerged during the initial analysis as having the most synergy with the included literature, themes were refined to consider key concepts from this theory.

PARTICIPANTS

Pregnant women who are self-managing a chronic condition.

RESULTS

A total of 2695 articles were screened and 25 were reviewed in detail. All 16 included studies concerned diabetes self-management in pregnancy. Common themes coalesced around motivations for, and barriers to, self-management. Women self-managed primarily for the health of their baby. Barriers identified were anxiety, lack of understanding and a lack of support from families and healthcare professionals.

CONCLUSIONS

Pregnant women have different motivating factors for self-management than the general population and further research on a range of self-management of chronic conditions in pregnancy is needed.

Mobile health in preventive cardiology: current status and future perspective

PURPOSE OF REVIEW

Despite cutting edge acute interventions and growing preventive strategies supported by robust clinical trials, cardiovascular disease (CVD) has stubbornly persisted as a leading cause of death in the United States and globally. The American Heart Association recognizes mobile health technologies (mHealth) as an emerging strategy in the mitigation of CVD risk factors, with significant potential for improving population health. The purpose of this review is to highlight and summarize the latest available literature on mHealth applications and provide perspective on future directions and barriers to implementation.

RECENT FINDINGS

While available randomized controlled trials and systematic reviews tend to support efficacy of mHealth, published literature includes heterogenous approaches to similar problems with inconsistent results. Some of the strongest recent evidence has been focused on the use of wearables in arrhythmia detection. Systematic reviews of mHealth approaches demonstrate benefit when applied to risk factor modification in diabetes, cigarette smoking cessation, and physical activity/weight loss, while also showing promise in multi risk factor modification via cardiac rehabilitation.

SUMMARY

Evidence supports efficacy of mHealth in a variety of applications for CVD prevention and management, but continued work is needed for further validation and scaling. Future directions will focus on platform optimization, data and sensor consolidation, and clinical workflow integration. Barriers include application heterogeneity, lack of reimbursement structures, and inequitable access to technology. Policies to promote access to technology will be critical to evidence-based mHealth technologies reaching diverse populations and advancing health equity.

SMS-facilitated home blood pressure monitoring: A qualitative analysis of resultant health behavior change

OBJECTIVE

Hypertension is largely asymptomatic and, as a result, patients often fail to sufficiently engage in medication adherence and other health behaviors to control their blood pressure (BP). This study explores the mechanisms by which MyBP, an automated SMS-facilitated home blood pressure monitoring (HBPM) program, helps facilitate healthy behavior changes.

METHODS

A thematic analysis of transcribed audio-recordings from semi-structured post-intervention interviews (n = 40) was conducted.

RESULTS

Three primary themes were identified as contributing most to patients' decision to initiate a behavior change: 1) increased hypertension literacy attributed to educational videos presented at enrollment, 2) increased day-to-day salience of blood pressure levels as a result of consistent HBPM, and 3) use of BP readings as feedback, with high readings triggering motivations to make behavior changes. These themes and most accompanying sub-themes correspond to constructs in the Health Belief Model and Social Cognitive Theory.

CONCLUSION

Patient-centered HBPM interventions such asMyBP appear to promote improvements in hypertension self-management via several mechanisms consistent with recognized models of behavior change.

PRACTICE IMPLICATIONS

SMS-supported HBPM, paired with video-based education, may provide a simple and scalable way of encouraging health behavior adherence in hypertensive patients.

Feasibility of a New Cuffless Device for Ambulatory Blood Pressure Measurement in Patients With Hypertension: Mixed Methods Study

Background

Frequent home blood pressure (BP) measurements result in a better estimation of the true BP. However, traditional cuff-based BP measurements are troublesome for patients.

Objective

This study aimed to evaluate the feasibility of a cuffless device for ambulatory systolic blood pressure (SBP) measurement.

Methods

This was a mixed method feasibility study in patients with hypertension. Performance of ambulatory SBPs with the device was analyzed quantitatively by intrauser reproducibility and comparability to a classic home BP monitor. Correct use by the patients was checked with video, and user-friendliness was assessed using a validated questionnaire, the System Usability Scale (SUS). Patient experiences were assessed using qualitative interviews.

Results

A total of 1020 SBP measurements were performed using the Checkme monitor in 11 patients with hypertension. Duplicate SBPs showed a high intrauser correlation (R=0.86, P<.001). SBPs measured by the Checkme monitor did not correlate well with those of the different home monitors (R=0.47, P=.007). However, the mean SBPs measured by the Checkme and home monitors over the 3-week follow-up were strongly correlated (R=0.75, P=.008). In addition, 36.4% (n=4) of the participants performed the Checkme measurements without any mistakes. The mean SUS score was 86.4 (SD 8.3). The most important facilitator was the ease of using the Checkme monitor. Most important barriers included the absence of diastolic BP and the incidental difficulties in obtaining an SBP result.

Conclusions

Given the good intrauser reproducibility, user-friendliness, and patient experience, all of which facilitate patients to perform frequent measurements, cuffless BP monitoring may change the way patients measure their BP at home in the context of ambulant hypertension management.

Health-related knowledge on hypertension among the Portuguese population: results from a population-based survey

PURPOSE

Adequate knowledge on hypertension has been shown to improve awareness, adherence to treatment and control of the disease. We aimed to estimate the health-related knowledge about hypertension among the Portuguese population.

MATERIALS AND METHODS

A representative sample of Portuguese-speaking dwellers in mainland Portugal (n = 1624), aged 16 to 79 years, was evaluated through face-to-face interviews conducted using a structured questionnaire. Health literacy was evaluated using the instrument Newest Vital Sign.

RESULTS

The mean prevalence of hypertension in the Portuguese population estimated by the participants in this study was 45.4%. Salt intake and poor diet were reported as main causes of hypertension by 27.5% and 21.5% of the participants, respectively, whereas more than 85% acknowledged myocardial infarction and stroke as its main consequences. However, 31.2% of the participants were not able to identify a cause for high blood pressure, especially the older and those with worse scores for health literacy. The accurate interpretation of blood pressure values diminished with the increase of systolic and diastolic blood pressure figures provided as examples for interpretation, from approximately 80% for 95/60 mmHg to 50% for 180/100 mmHg. Women and participants with greater levels of education or a previous diagnosis of hypertension tended to interpret blood pressure values correctly more often.

CONCLUSIONS

This study provided a quantitative estimate of the gaps in health-related knowledge about hypertension among the general population. Understanding the barriers that hinder the achievement of health-related knowledge on hypertension is expected to contribute for the global improvement of prevention and management of hypertension.

Thinking with care infrastructures: people, devices and the home in home blood pressure monitoring

The growing consumer market in health monitoring devices means that technologies that were once the preserve of the clinic are moving into spaces such as homes and workplaces. We consider how one such device, blood pressure monitors, comes to be integrated into everyday life. We pursue the concept of 'care infrastructure', drawing on recent scholarship in STS and medical sociology, to illuminate the work and range of people, things and spaces involved in self-monitoring. Drawing on a UK study involving observations and interviews with 31 people who have used a consumer blood pressure monitor, we apply the concept beyond chronic illness, to practices involving consumer devices - and develop a critical account of its value. We conclude that the care infrastructure concept is useful to highlight the socio-material arrangements involved in self-monitoring, showing that even for ostensibly personal devices, monitoring may be a shared practice that expresses care for self and for others. The concept also helps draw attention to links between different objects and spaces that are integral to the practice, beyond the device alone. Care infrastructure draws attention to the material, but ensures that analytic attention engages with both material and social elements of practice and their connections.

Self-monitoring blood pressure in hypertension, patient and provider perspectives: A systematic review and thematic synthesis

OBJECTIVE

To systematically review the qualitative evidence for patient and clinician perspectives on self-measurement of blood pressure (SMBP) in the management of hypertension focussing on: how SMBP was discussed in consultations; the motivation for patients to start self-monitoring; how both patients and clinicians used SMBP to promote behaviour change; perceived barriers and facilitators to SMBP use by patients and clinicians.

METHODS

Medline, Embase, PsycINFO, Cinahl, Web of Science, SocAbs were searched for empirical qualitative studies that met the review objectives. Reporting of included studies was assessed using the COREQ framework. All relevant data from results/findings sections of included reports were extracted, coded inductively using thematic analysis, and overarching themes across studies were abstracted.

RESULTS

Twelve studies were included in the synthesis involving 358 patients and 91 clinicians. Three major themes are presented: interpretation, attribution and action; convenience and reassurance v anxiety and uncertainty; and patient autonomy and empowerment improve patient-clinician alliance.

CONCLUSIONS

SMBP was successful facilitating the interaction in consultations about hypertension, bridging a potential gap in the traditional patient-clinician relationship.

PRACTICE IMPLICATIONS

Uncertainty could be reduced by providing information specifically about how to interpret SMBP, what variation is acceptable, adjustment for home-clinic difference, and for patients what they should be concerned about and how to act.

Patient experiences with self-monitoring renal function after renal transplantation: results from a single-center prospective pilot study

BACKGROUND

After a kidney transplantation, patients have to visit the hospital often to monitor for early signs of graft rejection. Self-monitoring of creatinine in addition to blood pressure at home could alleviate the burden of frequent outpatient visits, but only if patients are willing to self-monitor and if they adhere to the self-monitoring measurement regimen. A prospective pilot study was conducted to assess patients' experiences and satisfaction.

MATERIALS AND METHODS

For 3 months after transplantation, 30 patients registered self-measured creatinine and blood pressure values in an online record to which their physician had access to. Patients completed a questionnaire at baseline and follow-up to assess satisfaction, attitude, self-efficacy regarding self-monitoring, worries, and physician support. Adherence was studied by comparing the number of registered with the number of requested measurements.

RESULTS

Patients were highly motivated to self-monitor kidney function, and reported high levels of general satisfaction. Level of satisfaction was positively related to perceived support from physicians (P<0.01), level of self-efficacy (P<0.01), and amount of trust in the accuracy of the creatinine meter (P<0.01). The use of both the creatinine and blood pressure meter was considered pleasant and useful, despite the level of trust in the accuracy of the creatinine device being relatively low. Trust in the accuracy of the creatinine device appeared to be related to level of variation in subsequent measurement results, with more variation being related to lower levels of trust. Protocol adherence was generally very high, although the range of adherence levels was large and increased over time.

CONCLUSION

Patients' high levels of satisfaction suggest that at-home monitoring of creatinine and blood pressure after transplantation offers a promising strategy. Important prerequisites for safe implementation in transplant care seem to be support from physicians and patients' confidence in both their own self-monitoring skills and the accuracy of the devices used.
