Semmelweis University

EXECUTIVE SUMMARY AND STRATEGIC VISION

Semmelweis University presents a robust and balanced scientific integrity profile, with an overall risk score of -0.036 that indicates general alignment with expected standards. The institution demonstrates exceptional strengths in foundational areas of research quality, including extremely low rates of retracted output, institutional self-citation, and publication in discontinued journals. These results signal a strong culture of quality control and a commitment to external validation. However, areas of vulnerability emerge in practices related to authorship and collaborative impact, such as a high rate of multiple affiliations, hyper-authorship, and a significant gap between its overall impact and the impact of research it leads. These challenges, while reflecting some national trends, are more pronounced at the university and require strategic attention. The institution's world-class standing, evidenced by its top national rankings in key SCImago Institutions Rankings areas like Medicine, Dentistry, Pharmacology, and Biochemistry, Genetics and Molecular Biology, is undeniable. Yet, to fully honor its mission of "protecting and serving health" through excellence, it is crucial to ensure that its impressive impact is built upon sustainable internal leadership and transparent authorship practices. By addressing these specific vulnerabilities, Semmelweis University can further solidify its position as a global leader whose scientific contributions are as integral as they are impactful.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The university's Z-score of 0.861 is notably higher than the national average of 0.726, placing it in a position of high exposure to this particular risk. Although a medium level of multiple affiliations is a systemic pattern in the country, the institution shows a greater propensity for this activity. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, this elevated rate suggests the university is more susceptible than its peers to strategic practices aimed at inflating institutional credit. This warrants a review to ensure that all affiliations are substantive and reflect genuine collaboration rather than "affiliation shopping," thereby safeguarding the transparency of institutional contributions.

Rate of Retracted Output

With a Z-score of -0.616, the university demonstrates an exceptionally low rate of retracted publications, performing significantly better than the national average of -0.233. This result reflects a low-profile consistency, where the institution's near-total absence of risk signals aligns with, and even surpasses, the country's already low-risk standard. Retractions can sometimes signify responsible supervision through the correction of honest errors. In this context, the extremely low score is a strong indicator of robust and effective pre-publication quality control mechanisms, suggesting that the institutional culture of integrity and methodological rigor successfully prevents the types of errors or malpractice that might lead to retractions.

Rate of Institutional Self-Citation

The institution shows a remarkable strength in this area, with a Z-score of -0.788, which contrasts sharply with the national average of 0.310. This signifies a case of preventive isolation, where the university actively avoids the risk dynamics observed elsewhere in the country. A certain level of self-citation is natural, but the country's medium-risk score points to a broader tendency toward scientific isolation. Semmelweis University's very low score indicates that its research is validated by the global community, not confined to an internal 'echo chamber.' This demonstrates a healthy integration into international scientific discourse and confirms that its academic influence is driven by external recognition rather than endogamous impact inflation.

Rate of Output in Discontinued Journals

The university's Z-score of -0.376 is firmly in the very low-risk category, outperforming the national low-risk average of -0.189. This low-profile consistency indicates that the institution's strong performance is in harmony with the national standard for responsible publication. A high rate of publication in such journals would be a critical alert regarding due diligence, but the university's excellent score suggests its researchers exercise rigorous judgment in selecting dissemination channels. This protects the institution from the reputational damage associated with 'predatory' or low-quality practices and ensures that its scientific output appears in credible, enduring venues.

Rate of Hyper-Authored Output

With a Z-score of 1.250, the university shows a higher incidence of hyper-authored publications compared to the national average of 0.352. This indicates high exposure, suggesting the institution is more prone to this risk than its peers, even though the practice is present nationally. In medical fields like genomics, extensive author lists can be legitimate. However, this significantly elevated score serves as a signal to distinguish between necessary massive collaboration and potential author list inflation. It is crucial to verify that these extensive author lists reflect genuine contributions and not 'honorary' or political authorship, which can dilute individual accountability and transparency.

Gap between Impact of total output and the impact of output with leadership

The university exhibits a Z-score of 2.435 in this indicator, a figure substantially higher than the national average of 0.826. This reflects a high exposure to sustainability risk, as the institution is more prone than its national counterparts to this specific vulnerability. A wide positive gap suggests that the university's overall scientific prestige is heavily dependent on external collaborations where it may not exercise intellectual leadership. This invites critical reflection on whether its high-impact metrics are the result of genuine internal capacity or strategic positioning in partnerships. To ensure long-term sustainability, it is vital to foster and promote research where institutional authors take the lead.

Rate of Hyperprolific Authors

The university's Z-score of 0.087 indicates a medium-level risk, which represents a moderate deviation from the national context, where the score is -0.462 (low risk). This suggests the institution shows greater sensitivity to this risk factor than its peers. While high productivity can be a sign of leadership, extreme publication volumes challenge the limits of meaningful intellectual contribution. This indicator serves as an alert to potential imbalances between quantity and quality, pointing to the need to review for risks such as coercive authorship or the assignment of authorship without real participation—dynamics that prioritize metrics over the integrity of the scientific record.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the university demonstrates a very low reliance on its own journals, standing in stark contrast to the national average of 0.703 (medium risk). This is a clear example of preventive isolation, where the institution does not replicate the risk dynamics prevalent in its environment. Excessive dependence on in-house journals can raise conflicts of interest and lead to academic endogamy by bypassing independent external peer review. The university's excellent performance here indicates a strong commitment to global visibility and competitive validation, ensuring its scientific production is vetted through standard international channels and avoiding the use of internal 'fast tracks' to inflate output.

Rate of Redundant Output

The university's Z-score for redundant output is 0.222, which, while indicating a medium risk, is considerably lower than the national average of 0.409. This demonstrates differentiated management, where the institution effectively moderates a risk that appears to be more common across the country. A high value in this indicator typically points to 'salami slicing'—the practice of fragmenting a study into minimal publishable units to inflate productivity. The university's ability to maintain a lower rate than the national average suggests that its internal controls and academic culture are more effective at encouraging the publication of significant, coherent bodies of work over fragmented outputs.
