The Medical University of Varna presents a robust and largely positive scientific integrity profile, with an overall score of -0.137 indicating a performance that is well-aligned with expected standards. The institution demonstrates exceptional strengths in areas critical to academic credibility, showing very low-risk signals for Multiple Affiliations, Institutional Self-Citation, Hyperprolific Authors, and Output in Institutional Journals, often outperforming the national context. These results reflect a solid foundation of responsible research practices. However, a significant vulnerability is identified in the high dependency on external collaborations for impact, alongside medium-level risks in publication strategies like hyper-authorship and the use of discontinued journals. The University's leadership in key thematic areas, as evidenced by its SCImago Institutions Rankings—notably ranking 1st in Bulgaria for Pharmacology, Toxicology and Pharmaceutics, 2nd for Biochemistry, Genetics and Molecular Biology, and 4th for Medicine—is undeniable. Yet, the identified risk of low intellectual leadership in collaborations directly challenges its mission to "develop fundamental and applied scientific research, innovations and new technologies." To fully realize its mission and ensure long-term sustainability, the University should leverage its strong integrity foundation to strategically foster internal research leadership, thereby transforming its collaborative success into structural, self-sustaining excellence.
With a Z-score of -1.274, the institution demonstrates a very low rate of multiple affiliations, performing even better than the national average of -0.068. This result indicates a clear and transparent approach to academic collaboration, where affiliations are managed with integrity. The absence of risk signals in this area aligns with the low-risk national standard, confirming that the University avoids practices like "affiliation shopping" and ensures that institutional credit is claimed legitimately, reflecting genuine partnerships.
The institution's Z-score of -0.324 is in the low-risk category, slightly better than the national average of -0.191. This prudent profile suggests that the University's quality control mechanisms prior to publication are managed with more rigor than the national standard. While retractions are not entirely absent, their low frequency indicates that internal supervision and methodological standards are effective in minimizing errors and potential malpractice, thereby safeguarding the institution's scientific record.
A Z-score of -1.597 places the institution in the very low-risk category, in stark contrast to the medium-risk national average of 1.380. This demonstrates a remarkable preventive isolation from national trends toward academic endogamy. By avoiding the "echo chambers" that can arise from excessive self-citation, the University ensures its research is validated by the global scientific community, not just internally. This commitment to external scrutiny confirms that its academic influence is based on broad recognition rather than inflated internal dynamics.
The institution presents a medium-risk Z-score of 0.242, which is notably better than the national average of 0.691. This reflects a differentiated management approach, where the University successfully moderates a risk that appears more common across the country. Although there is still some exposure to journals that may not meet international quality standards, the institution demonstrates a greater capacity for due diligence in selecting dissemination channels, thereby better protecting its resources and reputation from predatory or low-quality practices.
With a Z-score of 0.407, the institution shows a medium level of risk that is higher than the national average of 0.149. This indicates a high exposure to publication practices that can dilute individual accountability. This elevated signal suggests that the institution is more prone than its national peers to author list inflation. It serves as an alert to review authorship practices and distinguish between necessary large-scale collaboration and potential "honorary" authorships that could compromise transparency.
The institution's Z-score of 4.591 is a significant risk indicator, dramatically accentuating the vulnerability already present in the national system (Z-score of 0.831). This critical value signals a profound dependency on external partners for citation impact, suggesting that the University's scientific prestige is largely exogenous and not yet structural. The wide gap warns that while the institution participates in high-impact research, it rarely exercises intellectual leadership. This poses a long-term sustainability risk and calls for a strategic reflection on how to build genuine internal capacity for innovation.
The institution's Z-score of -1.111 is in the very low-risk range, surpassing the already low national average of -0.770. This excellent result points to a healthy research environment where the balance between quantity and quality is maintained. The absence of risk signals confirms that the institutional culture does not encourage dynamics such as coercive authorship or assigning credit without real participation, thus protecting the integrity of the individual scientific record.
With a Z-score of -0.268, the institution shows a very low-risk profile, effectively isolating itself from the medium-risk national trend (Z-score of 1.113). This is a sign of exceptional governance, demonstrating a firm commitment to independent, external peer review. By avoiding the conflicts of interest and academic endogamy associated with excessive reliance on in-house journals, the University ensures its scientific production is validated against competitive global standards, enhancing its international visibility and credibility.
The institution has a medium-risk Z-score of 0.153, which indicates significantly better performance than the national average of 0.832. This reflects a differentiated management of publication output, where the University is more effective at moderating the common national practice of data fragmentation. While the risk of artificially inflating productivity through "salami slicing" exists, the institution's lower score suggests a stronger focus on publishing coherent and significant studies over prioritizing sheer volume.
