Understanding Patient Perspectives on Specialized, Longitudinal, Postpartum, Cardiovascular Risk-Reduction Clinics.

Background: Females who experience hypertensive disorders of pregnancy (HDP) have an increased lifelong risk of cardiovascular disease. Thus, Canadian clinical practice guidelines recommend cardiovascular risk reduction follow-up after a patient has HDP. This study examined the experiences of patients with HDP who attended a specialized, longitudinal general internal medicine postpartum cardiovascular risk reduction clinic called PreVASC. PreVASC focuses on comprehensive cardiovascular risk reduction through cardiovascular risk factor screening and management tailored specifically for female patients after they have HDP. Methods: This multimethod study examined the experiences of female patients with HDP via the following: (i) a quantitative survey (summarized with descriptive statistics); (ii) semistructured qualitative patient phone interviews (results grouped thematically); and (iii) triangulation of qualitative themes with quantitative survey results. Results: Overall, 37% of eligible clinic patients (42 of 115) participated; 79% of participants (n = 33) reported being "very satisfied" with the PreVASC clinic's specialized longitudinal model of care, and 95% (n = 40) reported making at least one preventive health behaviour change after receiving individualized counselling on cardiovascular risk reduction. Qualitative results found improvements in patient-reported cardiovascular health knowledge, health behaviours, and health-related anxiety. A preference for in-person vs phone clinic visits was reported by participants. Conclusions: An in-person, general internal medicine specialist-led, longitudinal model of cardiovascular disease preventive care focused specifically on cardiovascular risk reduction after HDP had positive impacts on patient experience, health knowledge, and preventive health behaviours. This novel knowledge on patient preferences for a longitudinal, specialized model of care advances cardiovascular risk reduction tailored specifically for high-risk people after HDP.

Contexte: Les femmes qui sont atteintes de troubles hypertensifs de la grossesse (THG) présentent un risque accru de maladie cardiovasculaire durant leur vie. Par conséquent, les lignes directrices canadiennes de pratique clinique recommandent un suivi pour la réduction du risque cardiovasculaire après la survenue d'un THG. Cette étude visait à examiner l'expérience des patientes qui ont été atteintes de THG et qui ont fréquenté l'une des cliniques de médecine interne spécialisées dans la réduction du risque cardiovasculaire post-partum et offrant une prise en charge longitudinale (PreVASC). Les cliniques PreVASC se concentrent sur la réduction des risques cardiovasculaires globaux par la détection des facteurs de risque cardiovasculaire et une prise en charge spécialement adaptée pour les femmes qui ont subi un THG. Méthodologie: Cette étude visait à examiner l'expérience des femmes atteintes d'un THG en faisant appel à diverses méthodes : i) sondage quantitatif (résumé par des statistiques descriptives); ii) entrevues téléphoniques semi-structurées de nature qualitative avec des patientes (résultats regroupés par thèmes); et iii) triangulation des thèmes qualitatifs et des résultats du sondage quantitatif. Résultats: Globalement, 37 % des patientes admissibles (42 sur 115) ont participé à l'étude; 79 % des participantes (n = 33) ont déclaré être « très satisfaites ¼ du modèle de soins longitudinal spécialisé des cliniques PreVASC, et 95 % (n = 40) ont déclaré avoir adopté au moins un comportement préventif pour leur santé après avoir reçu des conseils personnalisés sur la réduction du risque cardiovasculaire. Les résultats qualitatifs obtenus auprès des patientes font état d'une amélioration des connaissances sur la santé cardiovasculaire, les comportements sains et l'anxiété liée à la santé. Les participantes ont dit préférer les visites cliniques en personne aux consultations par téléphone. Conclusions: L'adoption d'un modèle longitudinal de médecine interne comprenant des rencontres avec des spécialistes pour prévenir les maladies cardiovasculaires, en particulier réduire le risque cardiovasculaire après un THG a eu des effets positifs chez les patientes en ce qui concerne l'expérience, les connaissances en matière de santé et les comportements à adopter pour prévenir les problèmes de santé. Ces nouvelles connaissances sur les préférences des patientes à l'égard de soins longitudinaux spécialisés représentent un pas en avant dans la mise en place d'une approche personnalisée de réduction du risque cardiovasculaire pour les personnes présentant un risque élevé après un THG.

Compliance with a perinatal prophylaxis policy for prevention of venous thromboembolism after caesarean section.

OBJECTIVE: To assess physician compliance, before and after a quality improvement intervention, with a regional policy on postpartum thromboprophylaxis following Caesarean section (CS), and to compare clinical outcomes (reduction of venous thromboembolism or increase in postpartum bleeding) between groups. METHODS: We performed a retrospective chart review of deliveries by CS, 404 prior to and 451 subsequent to a quality improvement intervention. All subjects were classified as being at either moderate or high risk for venous thromboembolism based on a risk-factor assessment, and warranted postpartum thromboprophylaxis according to the regional policy. Data regarding thromboembolism risk factors, postpartum thromboprophylaxis received, and clinical outcomes were recorded. RESULTS: Initial compliance with the regional policy was poor, but improved following the intervention. The use of intermittent pneumatic compression devices increased from 32% to 84% (P < 0.001), use of anticoagulation increased from 6.2% to 46% (P < 0.001), and full compliance with the policy increased from 1.7% to 30% (P < 0.001). Clinical outcomes were not significantly different between the groups. CONCLUSION: A quality improvement intervention markedly increased physician compliance with a regional policy on postpartum thromboprophylaxis among women at moderate to high risk of venous thromboembolism after CS. Adverse clinical outcomes were infrequent in this small study population.

Transient gestational hypertension: Not always a benign event.

OBJECTIVE: Pregnancy outcome in women with transient gestational hypertension (TGH);defined as de novo blood pressure elevation after 20weeks gestation that normalizes by subsequent evaluation in a Day Assessment Unit. STUDY DESIGN: Retrospective cohort analysis of hypertensive pregnancies between 2003 and 2008. MAIN OUTCOME MEASURES: Final hypertensive delivery diagnosis and composites of adverse maternal and fetal outcome. RESULTS: Overall 1417 women were referred; 890 met criteria; 41% (65% of study population) had TGH. Twenty percent with TGH developed gestational hypertension and 19% preeclampsia. Women with TGH who developed preeclampsia had similar composite adverse maternal outcomes to other preeclamptic women (51% vs. 63%; p=0.24) but fewer adverse fetal outcomes (50% vs. 71%; p<0.01) due to less prematurity (30% vs. 45%; p=0.02) and small for gestational age babies (33% vs. 51%; p=0.02). Within the TGH population;developing gestational hypertension or preeclampsia was associated with referral at gestation <33weeks (RRR 2.8; p<0.01);initial average systolic blood pressure 130-139mmHg (RRR 2.1; p<0.01) and initial average diastolic blood pressure 80-89mmHg (RRR 3.2; p<0.01). CONCLUSION: TGH after 20weeks is common in pregnancy. Although initial assessment implies low risk;the risk of progression to gestational hypertension or preeclampsia is substantial and warrants appropriate clinical surveillance.
