Exploring education preferences of Australian women regarding long-term health after hypertensive disorders of pregnancy: a qualitative perspective

Effect of Comprehensive Educational Program on Preeclamptic Women's Risk Perception of Cardiovascular Disease, Self-Efficacy, and Adherence to Healthy Lifestyle Behaviors

PURPOSE

To evaluate the effect of a comprehensive educational program on preeclamptic women's knowledge, risk perception of cardiovascular disease, self-efficacy, and adherence to healthy lifestyle behaviors.

PATIENTS AND METHODS

This study employed a pretest-posttest design. One hundred and two women who previously had preeclampsia were enrolled from July 2022 to December 2022 from outpatient obstetrics, gynecology, and family planning clinics. The primary and secondary outcomes were measured at baseline, after eight weeks, and after three months of the educational intervention. The data were analyzed using SPSS version 23, descriptive and inferential statistics, specifically the Chi-square test, independent t-tests, and repeated measures ANOVA.

RESULTS

A statistically significant difference was found between the two groups immediately post-intervention and the three-month follow-up, with a significant improvement among the intervention group than control group regarding cardiovascular disease knowledge (p < 0.001), risk perception (p < 0.001), self-efficacy (p < 0.001), and healthy lifestyle behaviors (p < 0.001). There was a statistically significant interaction between group and time regarding total cardiovascular disease risk perception (F = 203.67, p < 0.001, η2 = 0.673), self-efficacy (F = 70.06, p < 0.001, η2 = 0.405), and adherence to healthy lifestyle behaviors (F = 145.08, p < 0.001, η2 = 0.597).

CONCLUSION

This study concluded that the comprehensive educational program had a positive effect on improving preeclamptic women's knowledge and risk perception of CVD, self-efficacy, and adherence to healthy lifestyle behaviors following preeclampsia.

Postpartum care in a cardio-obstetric clinic after preterm preeclampsia: patient and healthcare provider perspectives

BACKGROUND

Despite the significant disruption and health implications of preterm preeclampsia with severe features for birthing people, little is known about how the system of postpartum care might be strengthened for affected families. Multidisciplinary cardio-obstetric clinics are emerging; however, there is limited research on patient and healthcare provider perspectives.

OBJECTIVE

To describe patient and healthcare provider perspectives of services in a cardio-obstetric clinic following preterm preeclampsia with severe features.

STUDY DESIGN

Individuals who experienced preterm preeclampsia with severe features and presented to a cardio-obstetric clinic were approached for study participation. Providers were approached if they provided postpartum care to patients with preterm preeclampsia with severe features and considered a referral to the cardio-obstetric clinic. Participants completed a remotely conducted, semistructured interview between March 2022 and April 2023. The interviews were audio-recorded, professionally transcribed, and checked for accuracy. Responses were inductively coded for content analysis around the study questions of clinical referrals, patient education, visit expectations, and care coordination in relation to ambulatory clinical services.

RESULTS

Twenty participants (n=10 patients and n=10 providers) completed interviews. Healthcare system navigation was difficult, particularly in the context of postpartum needs. When patients are informed about their diagnosis, the information could both increase anxiety and be useful for long-term healthcare planning. Language concordant care did not always occur, and both patients and providers described gaps in quality services. Within the theme of responsibility, patients described needing to be vigilant, and providers recognized the gaps in referral and care coordination systems. Comprehensible patient education provided with birthing parents' companions and enhanced systems for care coordination were areas for further improvement in providing postpartum cardio-obstetric care following preterm preeclampsia.

CONCLUSION

This qualitative study identified patients' struggles with a confusing postpartum healthcare system and captured providers' concerns about maintaining consistent care and improving access to long-term healthcare services to improve outcomes for patients at risk of cardiovascular disease.

Preeclampsia-Associated Cardiovascular Risk Factors 6 Months and 2 Years After Pregnancy: The P4 Study

BACKGROUND

Increased cardiovascular risk following preeclampsia is well established and there are signs of early cardiovascular aging 6 months postpartum. This study assessed whether blood pressure (BP) and other cardiovascular measures are abnormal 2 years postpartum in the same cohort to determine ongoing risk markers.

METHODS

Six months and 2 years postpartum, BP was measured using sphygmomanometry, 24-hour ambulatory BP monitoring, and noninvasive central BP. Anthropometric measures, blood, and urine biochemistry were performed. Cross-sectional comparisons between preeclampsia and normotensive pregnancy (NP) groups and longitudinal comparisons within each group were made at 6 months and 2 years.

RESULTS

Two years postpartum, 129 NP, and 52 preeclampsia women were studied who also had 6 months measures. At both time points, preeclampsia group had significantly higher BP (office BP 2 years, 112±12/72±8 versus 104±9/67±7 mm Hg NP; [P<0.001]; mean ambulatory BP monitoring 116±9/73±8 versus 106±8/67±6 mm Hg NP; [P<0.001]). No significant BP changes noted 6 months to 2 years within either group. Office BP thresholds of 140 mm Hg systolic and 90 mm Hg diastolic classified 2% preeclampsia and 0% NP at 2 years. American Heart Association 2017 criteria (above normal, >120/80 mm Hg) classified 25% versus 8% (P<0.002), as did our reference range threshold of 122/79 mm Hg. American Heart Association criteria classified 60% post-preeclampsia versus 16% after NP with above-normal ambulatory BP monitoring (P<0.001). Other cardiovascular risk markers more common 2 years post-preeclampsia included higher body mass index (median 26.6 versus 23.1, P=0.003) and insulin resistance.

CONCLUSIONS

After preeclampsia, women have significantly higher BP 6 months and 2 years postpartum, and have higher body mass index and insulin-resistance scores, increasing their future cardiovascular risk. Regular cardiovascular risk screening should be implemented for all who have experienced preeclampsia.

The long-term risk of cardiovascular disease among women with a history of hypertensive disorders of pregnancy: a systematic review of clinical practice guidelines

BACKGROUND

The lifelong risks of cardiovascular disease following preeclampsia and gestational hypertension are well-established. However, it is unclear whether this evidence has been translated into clinical practice guidelines. Thus, this review aimed to assess the quality and content of Australian clinical practice guidelines regarding the risk of cardiovascular disease following gestational hypertension and preeclampsia.

METHODS

We conducted a systematic search of MEDLINE (Ovid), EMBASE (Ovid), and CINAHL databases, as well as hospital, obstetric society, and medical college websites. Publications were included if: they were a clinical practice guideline; were published in the previous ten years; and included recommendations for the management of future cardiovascular disease risk following hypertensive disorders of pregnancy. Quality assessment was performed using Appraisal of Guidelines for Research and Evaluation Instrument Version Two (AGREE-II) and AGREE Recommendations Excellence Instrument (AGREE-REX).

RESULTS

Eighteen guidelines were identified, and of these, less than half (n = 8) included recommendations for managing future cardiovascular risk following hypertensive disorders of pregnancy. Across these eight, four main counselling recommendations were found regarding (1) risk of future cardiovascular disease; (2) risk factor screening; (3) lifestyle interventions; and (4) prenatal counselling for future pregnancies. The quality and content of these recommendations varied significantly, and the majority of guidelines (87.5%) were assessed as low to moderate quality.

CONCLUSIONS

There are limited Australian clinical practice guidelines providing appropriate advice regarding future risk of cardiovascular disease following hypertensive disorders of pregnancy. The quality and content of these guidelines varied significantly. These findings highlight the need for improved translation from evidence-based research to enhance clinical care and guidance.

Barriers and Facilitators to Cardiovascular Disease Prevention Following Hypertensive Disorders of Pregnancy in Primary Care: Cross-Sectional Surveys

Women with a history of hypertensive disorders of pregnancy (HDP) have an increased risk of cardiovascular disease (CVD). Guidelines recommend that women diagnosed with HDP should be advised of their increased CVD risk, have regular blood pressure monitoring by their general practitioner (GP), and adopt healthy lifestyle behaviours. However, within Australia, the current practice in primary health care is unknown. The aim of this study was to describe current practices, barriers, and facilitators to the provision of CVD preventative services for women after HDP in the primary care setting and to identify potential strategies to support GPs in providing recommended care. Separate cross-sectional online surveys were undertaken with 35 GPs and 105 women with a history of HDP. Surveys included both closed- and open-ended questions. Closed-ended questions were analysed using basic descriptive statistics, and open-ended questions were themed and tallied. The survey of GPs revealed that GPs are more likely to assess traditional CVD risk markers than lifestyle risk factors or HDP history. GPs identified a lack of resources and skills as barriers to providing CVD preventative care post-HDP. The survey with women after HDP revealed that women with a history of HDP are more likely to be assessed for blood pressure than lifestyle CVD risk factors, and that the women's barriers to obtaining care included difficulty obtaining an appointment and time required for attending appointments. Strategies to improve CVD preventative care were consistent between surveys, where 70% of GPs and 59% of women chose 'increasing women's awareness of increased CVD risk' and 67% of GPs and 55% of women chose 'improving communication between hospitals and primary care' as their preferred strategies. While the findings suggest that women with a history of HDP are receiving advice consistent with guidelines for traditional CVD risk markers, such as blood pressure, they are less likely to receive CVD preventative care for lifestyle or female-specific CVD risk factors.

The Association between Nutrition, Physical Activity, and Cardiometabolic Health at 6 Months following a Hypertensive Pregnancy: A BP2 Sub-Study

Hypertensive disorders of pregnancy (HDP) complicate 5-10% of pregnancies, with resultant lifelong increased risks of cardiovascular disease (CVD). We aimed to describe lifestyle behaviours at 6 months post-HDP in four HDP subgroups, and their association with markers of cardiometabolic health. Subgroups were chronic hypertension (CH), gestational hypertension (GH), preeclampsia, and preeclampsia superimposed on chronic hypertension (CH + PE). The BP2 study is a multi-site, three-arm, randomised controlled trial. At 6 months postpartum, the NSW Population Health Survey and BP2 surveys collected lifestyle behaviours and demographic data. Body mass index (BMI), waist circumference, and blood pressure (BP) were also assessed. Descriptive statistics, ANOVA and Spearman's correlation coefficients were used. Of 484 women (16% CH, 23% GH, 55% preeclampsia, and 6% CH + PE), 62% were overweight or obese. Only 6% met the recommended five vegetable and two fruit serves per day, and 43% did not meet the recommended 150 min of moderate-vigorous physical activity in five sessions per week. Adherence to both diet and physical activity recommendations was correlated with more favourable cardiometabolic outcomes, including lower BMI, waist circumference, and systolic and diastolic BP. Lifestyle interventions that improve diet and physical activity post-HDP are needed to reduce BP, BMI, and long-term CVD in this high-risk population.

Improving Cardiovascular Follow-Up after Diagnosis of a Hypertensive Disorder of Pregnancy using the Electronic Health Record

BACKGROUND

Cardiovascular disease is the leading cause of death among women. Sex-specific risk factors for cardiovascular disease include history of a hypertensive disorder of pregnancy.

PROBLEM

After diagnosis of a hypertensive disorder of pregnancy, professional societies recommend follow-up with a primary care provider for preventative care. There are gaps in patient and health care provider knowledge of the association between a hypertensive disorder of pregnancy and cardiovascular disease. That gap has a negative effect on patients receiving recommended follow-up.

METHODS

An electronic registry was created to identify those who gave birth in our health system and had a diagnosis of hypertensive disorder of pregnancy. From this, information outreach was sent electronically to the patient and their primary care provider.

INTERVENTIONS

Communication in the outreach included education on the association between hypertensive disorders of pregnancy and cardiovascular disease, the importance of follow-up, cardiopreventative strategies, and biochemical assessment. Medical records were audited at approximately 6 months postpartum to determine if patients completed a visit with their primary care provider to discuss cardiovascular risks.

RESULTS

Between May 2021 and June 2022, 15% ( n = 1,131) of patients who gave birth in our health system had a diagnosis of hypertensive disorder of pregnancy. Ninety percent of those patients who received outreach communication viewed the letter. At baseline, 16% of patients during postpartum with a hypertensive disorder of pregnancy saw their primary care provider to discuss cardiopreventative strategies. After implementation of our program, 26% of those with a hypertensive disorder of pregnancy saw their primary care provider for follow-up and discussed cardiopreventative strategies.

CLINICAL IMPLICATIONS

Nurses should ensure that women during postpartum and their primary care providers are educated about the association of hypertensive disorders of pregnancy and long-term cardiovascular risk. The electronic health record may be an optimal way to ensure education is provided and follow-up scheduled.

Patients' understanding of long-term cardiovascular risks and associated health-seeking behaviours after pre-eclampsia

OBJECTIVE

The lifelong risks of cardiovascular disease following hypertensive disorders of pregnancy are well described. Awareness of these risks and associated health-seeking behaviours among affected individuals remains unclear. We aimed to assess participants' knowledge of their cardiovascular disease risk and relevant health-seeking behaviours following a pregnancy affected by preeclampsia or gestational hypertension.

METHODS

We undertook a single-site, cross-sectional cohort study. The target population included individuals who birthed at a large tertiary referral centre in Melbourne, Australia, between 2016 and 2020, and were diagnosed with gestational hypertension or pre-eclampsia. Participants completed a survey assessing pregnancy details, medical comorbidities, knowledge of future risks and health-seeking behaviours post-pregnancy.

RESULTS

1526 individuals met inclusion criteria and 438 (28.6%) completed the survey. Of these, 62.6% (n=237) were unaware of their increased risk of cardiovascular disease following a hypertensive disorder of pregnancy. Participants who reported awareness of their increased risk were more likely to have annual blood pressure monitoring (54.6% vs 38.1%, p<0.01), and at least one assessment of blood cholesterol (p<0.01), blood glucose (p=0.03) and renal function (p=0.01). Participants who were aware were more likely to be taking antihypertensive medication (24.5% vs 6.6%, p<0.01) since pregnancy, compared with those who were unaware. There were no differences between groups in diet, exercise or smoking habits.

CONCLUSION

Among our study cohort, risk awareness was associated with increased health-seeking behaviours. Participants who were aware of their increased risk of cardiovascular disease were more likely to have regular cardiovascular risk factor assessments. They were also more likely to be taking antihypertensive medication.

Impact of Educational Interventions on Knowledge About Hypertensive Disorders of Pregnancy Among Pregnant Women: A Systematic Review

Background

Hypertensive disorders of pregnancy (HDP), including chronic hypertension, preeclampsia and gestational hypertension, is the cause of about 50,000 deaths out of 400,000 perinatal deaths. HDP is an effective risk factor in stroke, type 2 diabetes, and cardiovascular diseases like ischemic heart disease. There is a significant relation between HDP, lifestyle, and knowledge. Unfortunately, many studies showed that pregnant women have lack of knowledge about HDP. Therefore, the importance of educational interventions is, today, more acknowledged than before.

Aim

The goal of this systematic review was to investigate the effect of interventional educations on the knowledge of pregnant women about HDP.

Methods

A systematic review of the related articles was conducted. We included English randomized controlled trials published up to December 2021, including pregnant women as population, HDP as the outcome, and educational interventions as the intervention.

Results

After the process of study selection, six articles containing 819 pregnant women were included in this study. Educational pamphlets, mobile-based application, a mixture of pamphlets, pictographic magnet and videos, and a combination of PowerPoint and data show projectors and conversation were the educational interventions in these studies.

Conclusions

The positive effects of educational interventions on the knowledge of women with HTP were observed in all studies. The higher knowledge leads to HDP-related complications.

Preferences of Australian healthcare providers regarding education on long-term health after hypertensive disorders of pregnancy: a qualitative study

OBJECTIVES

To explore Australian healthcare providers' (HCPs') preferred content, format and access to education regarding long-term health after hypertensive disorder of pregnancy (HDP), in order to guide the development of education programmes.

DESIGN AND SETTING

A qualitative study using a framework analysis was undertaken. Registered HCP who were practising in Australia and previously completed a survey about long-term health after HDP were invited to participate.

PARTICIPANTS

Twenty HCP were interviewed, including midwives, specialist obstetrician/gynaecologists, general practitioners with a diploma in obstetrics and gynaecology, and cardiologists.

PRIMARY AND SECONDARY OUTCOME MEASURES

Exploration of preferred content, format and distribution of educational material post-HDP.

RESULTS

Twenty HCP were interviewed in April to May 2020. Four main categories were identified. 'Obtaining evidence-based information for own learning' addressing own learning with preference for multi-disciplinary education, preferably endorsed or facilitated by professional organisations. 'Optimising the referral process from hospital to community health services' was about the need for structured long-term follow-up to transition from hospital to community health and align with HDP guidelines. 'Facilitating women's health literacy' addressed the need for evidence-based, print or web-based material to assist risk discussions with women. 'Seizing educational opportunities' addressed the responsibility of all HCP to identify education opportunities to initiate key health discussions with women.

CONCLUSIONS

HCP provided ideas on content, format and access of education regarding long-term health post-HDP within the parameters of the Australian healthcare context. This evidence will guide educational developments for HCP on post-HDP health to ensure they can better care for women and families.
