Urgent need to increase the rates of diagnosing, treating and controlling hypertension in older women: A call for action

Community Pharmacy-Based Blood Pressure Screening in Newfoundland and Labrador, Canada for World Hypertension Day 2022: A Cross-Sectional Study

Background

High blood pressure (BP) is a leading cause of cardiovascular and stroke-related events. Office-based BP measurement has declined in recent years due to the COVID-19 pandemic, which may have resulted in higher rates of undetected and uncontrolled hypertension. To gain a better idea of adult BP levels in Newfoundland and Labrador, we engaged community pharmacists in BP screening on World Hypertension Day.

Methods

Data collection and BP screening occurred on May 17, 2022. Pharmacists and pharmacy students collected 3 seated BP readings from participants, using an automated device. The average of readings 2 and 3 was used to estimate BP, with elevated BP defined as ≥ 140/90 mm Hg, or ≥ 130/80 mm Hg for individuals with diabetes. Data on participant demographics, access to primary care, medical history, and antihypertensive use were also collected. Data analysis included descriptive statistics and logistic regression techniques.

Results

A total of 460 participants were included in the analysis. The mean age was 56.3 years (standard deviation: 16.95); 63.3% (n = 291) were female; and 43.7% (n = 201) reported having hypertension. Elevated BP was identified in 27% (n = 123). Of those with elevated BP, 41.5% (n = 51) had no history of diagnosed hypertension. Age, sex, and diabetes were statistically significant predictors of elevated BP in the multivariable model.

Conclusions

A large proportion of participants in our study had elevated BP. Targeted measures are needed to improve the detection, treatment, and control of high BP in Newfoundland and Labrador. Community pharmacists can support BP care.

Knowledge, perception and practice of Québec nurses for ambulatory and clinic blood pressure measurement methods: are we there yet?

BACKGROUND

Guidelines regarding blood pressure measurement (BPM) methods, namely home (HBPM), ambulatory (ABPM), office (OBPM) and automated (AOBP) are published by Hypertension Canada and rely on accurate measurement technique. Nurses commonly perform BPM but their knowledge, perception and practice considering all methods is understudied. This study is the first to establish the picture of Québec nurses working in primary care settings concerning the four BPM methods.

METHODS

All nurses licensed to practice in primary care in Québec were targeted in our survey. Data were collected using a validated and pretested investigator-initiated questionnaire in English and French. A personalized e-mail invitation, and two reminders, including a link to a secured platform was sent in December 2019. A certificate of ethics was issued by UQTR.

RESULTS

A total of 453 nurses participated in the study. Median age was 40 ± 11 years, and 92% were women. The overall score on BPM methods knowledge was slightly below 50% (46% ± 23). The perception was mostly positive, with an overall score above 50% (73% ± 8). In practice, HBPM was recommended by 47% of nurses, and ABPM by 18%. Although AOBP is the preferred method in Canada, only 25% of the nurses use it, including the 57% that use an oscillometric device and 11% that use manual auscultation.

CONCLUSION

Nurses working in primary care play a central role in BPM. Our results highlight that overall knowledge and practice are suboptimal. Resources should, therefore, be allocated to ensure that initial training and continuing education are addressed.

WHO HEARTS: A Global Program to Reduce Cardiovascular Disease Burden: Experience Implementing in the Americas and Opportunities in Canada

Globally, cardiovascular diseases (CVDs) are the leading cause of death. Viewed as a threat to the global economy, the United Nations included reducing noncommunicable diseases, including CVDs, in the 2030 sustainable development goals, and the World Health Assembly agreed to a target to reduce noncommunicable diseases 25% by the year 2025. In response, the World Health Organisation led the development of HEARTS, a technical package to guide governments in strengthening primary care to reduce CVDs. HEARTS recommends a public health and health system approach to introduce highly simplified interventions done systematically at a primary health care level and has a focus on hypertension as a clinical entry point. The HEARTS modules include healthy lifestyle counselling, evidence-based treatment protocols, access to essential medicines and technology, CVD risk-based management, team-based care, systems for monitoring, and an implementation guide. There are early positive global experiences in implementing HEARTS. Led by the Pan American Health Organisation, many national governments in the Americas are adopting HEARTS and have shown early success. Unfortunately, in Canada hypertension control is declining in women since 2010-2011 and the dramatic reductions in rates of CVD seen before 2010 have flattened when age adjusted and increased for rates that are not age adjusted, and there are marked increases in absolute numbers of Canadians with adverse CVD outcomes. Several steps that Canada could take to enhance hypertension control are outlined, the core of which is to implement a strong governmental nongovernmental collaborative strategy to prevent and control CVDs, focusing on HEARTS.
