A recent study sheds light on the challenges and motivations of pregnant and postpartum women regarding participation in thromboprophylaxis trials, essential for preventing venous thromboembolism.
Knowledge Deficits Impact Trial Engagement
The research involved four online focus groups with women who either had a history of venous thromboembolism or were offered thromboprophylaxis due to other risk factors during pregnancy and the puerperium. Conducted between November 2021 and January 2022, the study recruited a diverse group of participants through social media and special interest groups, ensuring a mix of conditions, ages, ethnicities, and socio-economic statuses.
Barriers and Motivations for Participation
Findings revealed that many women lacked a comprehensive understanding of the risks and benefits associated with thromboprophylaxis. This limited knowledge often led to a one-sided perception of the treatment’s benefits, making participants view placebo options unfavorably. Additionally, concerns about the discomfort of injections were frequently overlooked by healthcare providers, affecting adherence to treatment protocols.
- Limited awareness of treatment risks reduces balanced decision-making.
- Negative injection experiences may decrease adherence to thromboprophylaxis.
- Desire for higher standards of care drives interest in clinical trials.
The study emphasizes that enhancing communication about the risks and benefits of thromboprophylaxis could significantly improve both recruitment and retention in clinical trials involving pregnant and postpartum women. Clear explanations foster a better understanding of clinical equipoise, encouraging more informed participation.
Effective communication strategies not only support trial recruitment but also enhance the overall treatment experience for women currently receiving thromboprophylaxis. By addressing misconceptions and providing comprehensive information, healthcare professionals can improve adherence and outcomes, ultimately leading to better prevention of venous thromboembolism in this vulnerable population.
Empowering women with knowledge and addressing their concerns directly can transform their approach to participating in clinical research. This approach ensures that trials are more representative and that the findings are robust, benefiting future care standards for pregnant and postpartum women worldwide.
