Preconception care (PC) is relatively new area of practice. While the volume and quality of PC activities depend on local settings, the awareness of women is critical for the successful promotion of PC services. The aim of this study was to examine the preconception-health-related attitudes and experiences of Bulgarian women of reproductive age. A qualitative study conducted among 20 women aged 18 to 49 years was performed between May and July 2022. Two focus groups were used with mixed samples of nulligravida, pregnant, and postpartum women. The participants thought that the Internet and their obstetrician-gynecologist were the only places where they could learn about getting pregnant. Only two of them discussed their PC plans with their physicians. Women pointed out that general practitioners (GPs) need to be more proactive in promoting PC. All respondents outlined the need for a web-based educational platform that could serve as a primary source of health information for future families. The role and functions of GPs in the continuum of PC should be reconsidered. We recommend targeted educational measures for all stakeholders, including women and GPs. In this regard, an easily accessible, knowledge-based web platform could enhance Bulgarian women’s awareness and perceptions of PC.

Rare cancers are defined by an annual incidence of fewer than 6 per 100,000. Bearing similarities to rare diseases, they are associated with substantial health inequalities due to diagnostic complexity and delayed access to innovative therapies. This situation is further aggravated in Southeastern European countries like Bulgaria, where limited public resources and expertise underscore the need for additional policy and translational research on rare cancers. This study aimed to explore the availability and access to orphan drugs for rare cancers in Bulgaria for the period of 2020–2023. We cross-compared data from both the European Union and national public sources to evaluate the number of available and accessible orphan drugs for rare cancers, the delay from market authorization to reimbursement, the dynamics of public expenditures, and regional disparities in access across the country. We juxtaposed the main characteristics of oncological and non-oncological orphan drugs as well. Only 15 out of 50 oncological orphan drugs that were authorized by the European Medicine Agency were accessible for rare cancer patients in Bulgaria. The median delay between market authorization and inclusion in the Bulgarian Positive Drug List was 760 days. The total expenditures for all orphan drugs for rare cancers amounted to EUR 74,353,493 from 2020 to 2023. The budgetary impact of this group rose from 0.24% to 3.77% of total public medicinal product expenditures for the study period. Rare cancer patients represent a vulnerable population that often faces limited to no access to treatment. We call for targeted European and national policies to address this major inequality.

Background: Rare diseases (RDs) are life-threatening or chronically debilitating and offer a high level of complexity. The aim of this study is to assess medical students’ knowledge and awareness of RDs as well as their perceptions of potential measures to boost training in RDs. The cross-sectional survey was conducted at the Medical University of Plovdiv, Bulgaria, in 2019. The questionnaire contained 12 questions, divided into three main categories: (1) sociodemographic profile; (2) knowledge and awareness of RDs; and (3) attitudes about potential measures to improve training in RDs. Results: A total of 1189 medical students completed the survey with an overall response rate of 56.4%. Only 13% of participants knew the correct definition of RDs, and a low overall level of awareness was found with regard to orphan drugs (20.3%) and genetic counselling and testing (0.5%). Respondents believed that society as a whole was largely unaware of RDs as a major public health issue. Students suggested elective courses, and invited lectures by RDs experts, and participation in research projects as the most preferred measures to improve undergraduate training. Conclusions: It is crucial to address the gaps in medical students’ knowledge and awareness of RDs. University curricula should consider incorporating different RDs training modalities. It is essential to encourage various stakeholders to play a more proactive role and to collaborate in these activities. Involvement of patient organisations and advocacy groups might enhance students’ knowledge of the challenges faced by people with RDs. Not least, the media should be partners in this important endeavour as well.

Rare cancers, defined as those with an annual incidence of fewer than six cases per 100,000 individuals, are associated with significant health inequalities. This study aimed to assess the knowledge, attitudes, and perceptions of healthcare providers with expertise in rare cancers regarding the effectiveness of enacted or planned rare cancer policies across Europe. Between 25 March 2023 and 5 March 2024, we conducted an online survey targeting 738 healthcare providers affiliated with the European Reference Networks and the Organization of European Cancer Institutes, yielding 92 complete responses from 28 European countries (response rate: 12.5%). While a significant portion of respondents were unaware of their country’s legal definitions for rare cancers, 67.4% acknowledged that national cancer plans prioritized rare cancers. These plans received the highest ratings for their evidence-based interventions and monitoring efforts. The integration of rare cancer policies into broader oncology frameworks was the preferred policy model. National cancer registries were highly rated for confidentiality and validity but scored the lowest for cost-effectiveness. Government funding was deemed crucial for cancer screening programs. The disease burden and unmet health needs primarily influenced reimbursement decisions in the field of rare cancers. Respondents rated palliative care as more effective in adults with rare cancers compared to in children, particularly regarding symptom management. We confirmed significant variability in rare cancer policy evaluations across Europe, the necessity for a common EU-level definition for rare cancers, and a shift in reimbursement and policy framework models, highlighting the importance of policy integration and enhanced collaboration. However, given the limitations of the study, such as small sample size and possible unstudied confounding factors, we should interpret our findings with caution. A systematic policy review and multistakeholder assessment in the future could complement our results.

Gene therapies (GTs) have recently emerged as revolutionary personalized therapeutic options. Despite their promising potential, challenges such as uncertainty regarding long-term health benefits and safety, along with extreme price tags, pose significant obstacles to patient access. Within the EU, the European Medicines Agency plays a pivotal role with regards to GT market authorization. However, national authorities are responsible for pricing and reimbursement, which results in fragment patient access within the EU. This study aimed to provide an overview of the complex landscape of post-market authorization accessibility for GT products in Bulgaria, comparing it with neighboring EU countries. We applied a mixed-methods approach, including desk research, public data requests, and list price comparisons. As of 1 April 2023, 14 GTs had a valid market authorization at the EU level. In Bulgaria, Kymriah® was the only GT included in the Positive Drug List (PDL), with an official list price of EUR 335,636.94. Similar results were found in Romania, whereas five GTs were included in Greece’s PDL. Additionally, Zolgensma® was found accessible in Bulgaria through an alternative individual access scheme at an estimated price of EUR 1,945,000.00. In conclusion, this study emphasized targeted policy interventions to address health inequalities and to ensure timely access to GTs within the EU.

Assisting women in attaining their reproductive goals is crucial for improving the well-being of families and children. As the first point of contact for healthcare, general practitioners (GPs) are ideal for family planning (FP) and preconception care (PCC). However, primary care interventions’ efficacy is unclear. The aim of this study was to examine GPs’ knowledge, attitudes, and perspectives on FP and PCC service management. Most GPs were aware of FP and PCC services and held a firm conviction that they should be primarily accountable together with obstetrician–gynaecologists. However, it is worth noting that less than 50% of respondents reported receiving thorough and comprehensive knowledge of their respective specialities. Those with general medicine qualifications demonstrated a high level of commitment to providing such services. The women’s GPs and those with training in general medicine prescribed birth control pills and emergency contraception three times more frequently than the other doctors who suggested condoms or traditional methods or referred patients to another specialist (p < 0.05). In conclusion, PCC is of the utmost importance, and its effective implementation demands the collaboration of policymakers, healthcare providers, and individuals. GPs are essential in managing FP and PCC. They must incorporate more in-depth PCC into their clinical practice.
