Evaluating the Impact of COVID-19 Pandemic on Organ Donation and Transplantation Activities in Iran
Bibliographic record
Abstract
Background: Coronavirus disease 2019 (COVID-19) pandemic has had a great impact on reducing organ transplantation activities. Objectives: The aim of this study was to determine the donation and transplantation activities before and after COVID-19 outbreak in Iran. Methods: This retrospective study compared the donation and transplantation activities in two specific 9-month periods (average period of March - December 2019 Vs. March - December 2020). The questionnaire included the numbers of brain death confirmations, family consents, organ recoveries, and transplanted solid organs. The questionnaire was sent by email to the chief executive of the organ procurement unit. Results: A total of 15 organ procurement units responded to the survey. The largest reduction was seen in tissue transplantations (62.5%) during two time intervals. Brain death due to head trauma significantly decreased in two time intervals and suicide increased by 14.44% during the COVID-19 pandemic compared to 2018-2019 period. Significant reductions between the median of donation (P = 0.0187), median of potential donor (P = 0.005), median of family consent (P = 0.002), and median of eligible donor (P = 0.009) were observed during the two time periods. Conclusions: A significant reduction was observed in organ donation and transplantation during COVID-19 pandemic. Developing protocols and establishing new strategies for evaluation of organ donation to ensure the safety of organ recipients and medical staff is necessary.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
