Tehran University of Medical Sciences

EXECUTIVE SUMMARY AND STRATEGIC VISION

With a strong overall integrity score of 0.879, Tehran University of Medical Sciences demonstrates a robust research profile, marked by significant strengths but also punctuated by critical areas requiring strategic intervention. The institution's primary asset in scientific integrity is its exceptionally low rate of redundant output (salami slicing), indicating a commendable focus on substantive publications over sheer volume. However, this is offset by a significant-risk finding in the rate of output in institutional journals, which is a critical outlier both nationally and globally. This, combined with medium-risk indicators for hyperprolific authors and multiple affiliations that are higher than the national average, points to specific vulnerabilities in publication and authorship practices. These integrity metrics exist alongside world-class academic achievements, as evidenced by SCImago Institutions Rankings data, which place the university as a national and regional leader in key areas such as Dentistry (#1 in Iran), Medicine (#1 in Iran), and Biochemistry, Genetics and Molecular Biology (#1 in Iran). The identified risks, particularly the heavy reliance on internal journals, directly challenge the institutional mission to uphold the "highest educational standards," as such practices can circumvent the rigorous external validation that defines global excellence. To safeguard its prestigious reputation and fully align its operational practices with its mission, it is recommended that the university undertake a comprehensive review of its publication policies, focusing on promoting external dissemination channels and reinforcing authorship criteria to ensure that its impressive productivity is matched by unimpeachable transparency and integrity.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution's Z-score of 0.237 places it in a medium-risk category, representing a moderate deviation from the national Z-score of -0.615, which is considered low risk. This divergence indicates that the university shows a greater sensitivity to this risk factor than its national peers. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, the higher rate here could signal strategic attempts to inflate institutional credit or "affiliation shopping." This pattern warrants a review to ensure that all affiliations are substantive and reflect genuine collaborative contributions, rather than being used primarily for metric enhancement.

Rate of Retracted Output

With a Z-score of 0.267, the institution operates within a medium-risk zone, a finding consistent with the national context (Z-score: 0.777). However, the university's score is substantially lower than the country's average, suggesting a differentiated management of this risk. This indicates that while the institution is not immune to the systemic factors leading to retractions, its internal quality control mechanisms prior to publication appear to be more effective at mitigating these issues than those of its national peers. This relative success in moderating a common risk points to a more resilient integrity culture, though continued vigilance is necessary.

Rate of Institutional Self-Citation

The university's Z-score of -0.120 is in the low-risk category, closely mirroring the national Z-score of -0.262. Although both are low, the institution's slightly higher value points to an incipient vulnerability that warrants monitoring. A certain level of self-citation is natural and reflects the continuity of research lines. However, this subtle elevation above the national baseline serves as an early warning. If this trend were to grow, it could risk fostering scientific 'echo chambers' where the institution's work is validated internally without sufficient external scrutiny, potentially leading to an inflation of its perceived impact.

Rate of Output in Discontinued Journals

The institution's Z-score of 0.203 places it in a medium-risk category, a level higher than the national average of 0.094. This indicates a high exposure to this particular risk, suggesting the university is more prone to this issue than its environment. A high proportion of publications in discontinued journals is a critical alert regarding due diligence in selecting dissemination channels. This pattern suggests that a portion of the university's scientific output is being channeled through media that may not meet international ethical or quality standards, exposing the institution to severe reputational risks and signaling an urgent need to improve information literacy among its researchers.

Rate of Hyper-Authored Output

With a Z-score of -0.747, the institution demonstrates a low risk in this area, which is consistent with the national profile (Z-score: -0.952). However, the university's score is slightly higher than the country's, signaling an incipient vulnerability. While the overall risk is minimal, this subtle difference suggests that the institution has a slightly greater tendency toward publications with extensive author lists. This serves as a signal to proactively ensure that all authorship is justified by significant contributions, distinguishing necessary massive collaboration from any potential 'honorary' or political authorship practices that could dilute individual accountability.

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

The university's Z-score of 0.536 is in the medium-risk range and is higher than the national average of 0.445. This reveals a high exposure to dependency risk, as the gap between its overall publication impact and the impact of research it leads is wider than the national norm. This suggests that the institution's scientific prestige may be more reliant on its role in external collaborations where it does not exercise primary intellectual leadership. This finding invites a strategic reflection on whether its high-impact metrics are a result of genuine internal capacity or are more dependent on strategic positioning in partnerships led by others, which could pose a sustainability risk.

Rate of Hyperprolific Authors

The institution's Z-score of 1.236 indicates a medium-risk level, which is a moderate deviation from the low-risk national standard (Z-score: -0.247). This discrepancy highlights that the university is significantly more sensitive to this risk factor than its peers. Extreme individual publication volumes often challenge the limits of human capacity for meaningful intellectual contribution. This alert points to potential imbalances between quantity and quality, and may signal underlying risks such as coercive authorship, data fragmentation, 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 an exceptionally high Z-score of 6.620, the institution is in the significant-risk category, drastically amplifying a vulnerability that is already present at a medium level nationally (Z-score: 1.432). This finding constitutes a global red flag and points to a critical issue of academic endogamy. Such an extreme dependence on its own journals raises serious conflict-of-interest concerns, as the institution acts as both judge and party in the publication process. This practice strongly suggests that a substantial portion of its scientific production might be bypassing independent external peer review, potentially using internal channels as 'fast tracks' to inflate CVs without standard competitive validation, thereby limiting global visibility and credibility.

Rate of Redundant Output (Salami Slicing)

The institution's Z-score of -0.697 is in the very low-risk category, performing even better than the low-risk national average of -0.390. This demonstrates low-profile consistency and an operational strength. The absence of risk signals in this area aligns with the highest standards of scientific integrity. This result indicates that the university's researchers are not engaging in the practice of dividing coherent studies into minimal publishable units to artificially inflate productivity, but are instead focused on producing substantive work that provides significant new knowledge.
