Introduction: The opt-in system introduced in Mongolia in  March 2018. We analyzed  all  brain dead donors whose family members gave consent and matched with donor criteriias. Between March 2018 and March 2024, the regulatory department team got 27 consent (male: n=14, female =13) which were identified in three main donor hospitals.
Method: In Mongolia, brain death donor definition is patient with primary brain damage and been diagnosed and eligible as organ donor according to medical assessment. All these donors were treated in the ICU of the first, third central hospital and national trauma orthopedic research center. Identification and medical assessment of whether a patient was potential Brain death donor was made by the treating physician and supported by the brain death determination committee. Data were collected from the annual report of the regulatory department of cells, tissues and organs.  As per regulation the regulatory department has to get consent from the three family members.
Results: During the selected period, a total 27 utilized donors have been saved 64 (kidneys=39, liver=25) recipients’ lives and improved 173 people’s quality of life through tendon reconstruction surgeries at the first central hospital, national cancer center and national trauma orthopedic research center. Donor age was between 30 to 68 years old. The age of the potential donors had direct influence on the consent rate. Out of 27 donors, 22 (81.4%) were above 40 years old. The proportion of male recipients were higher comparing to donors. Total 64 recpients  (male: n=45, female =19) who were aged between 18-64 years old.
In 14 cases, donors were transported to donor hospital for recovering organs and tissues to shorten cold ishemia time. A total 58 recipients participated in survival survey study in December 2023 and patient survival rate 91.3% . Survey result showed that 5 recipients were passed away due to Covid-19 infections and hearts failures.
Conclusion: The results of this analysis of utilized donations for the last 5 years shows that potential donors age had direct influence on the consent rate. If the donor age is above 40, the consent rate will be higher than younger potential donor.
The organ recovery time has direct effect on result of patients survival.  At the end of December 2023, patient survival rate was 91.3% . However, liver function and complete blood cell results were  recorded in our reports, we did not analyze at this time  its relation to graft survival and patient survival.
