Organ shortage is considered to be a major limitation for increasing transplantation rates. Brain-dead donors (DBDs) are an important source of organs, but up to 50% of potential DBDs might not be identified. An active brain-dead donor search could potentially increase a deceased donor pool. The aim of this study was to evaluate the effectiveness of an active potential DBD identification program and to evaluate one year impact on the potential organ donor pool in Lithuania's biggest medical institution. An organ donor coordinator service was established and active DBD search strategy was implemented in the hospital of LSMU Kauno Klinikos, and retrospective data analysis was performed between December 2016 and December 2017. Collected data was compared to the available data of the previous year in the same center and to the donation dynamics of the whole country. A total of 6734 patients were treated in all intensive care units (ICU), and 234 (3.5%) of them were identified as possible donors. No increase in potential donor's number was observed in study year ( = 34) compared to remote year ( = 37). No significant difference in potential donor's demographic data, cause of death, family refusals and medical contraindication rates. Cerebral angiography (CA) repeated in 20% of potential donors in order to confirm brain death diagnosis. More potential donors for whom CA was repeated had decompressive craniectomy done (66.7% vs. 33.3%, = 0.018). Decompressive craniectomy statistically significantly increases the rate of repeated CA (OR 12.7; 95% CI, 1.42-113.37; = 0.023). Active search strategy increased length of hospital stay of potential donors comparing to previous year (3.97 ± 4.73 vs. 2.51 ± 2.63, = 0.003). An optimal time of the first four days of hospitalization to identify a potential donor was observed during our study (OR 10.42; 95% CI, 4.29-25.34; = 0.001). We were not able to demonstrate active donor identification strategy superiority over the passive strategy during a short one year period; nevertheless, valuable knowledge was gained in brain death diagnostics, new terminology was implemented, and the stability of actual donor numbers was observed in the experimental donor center in the light of decreasing national results. Long-term strategy is required to achieve sustainable results in organ donation.
器官短缺被认为是提高移植率的主要限制因素。脑死亡供体(DBD)是器官的重要来源,但多达 50%的潜在 DBD 可能无法识别。积极寻找脑死亡供体可能会增加潜在的已故供体群体。本研究旨在评估主动寻找潜在 DBD 的效果,并评估其在立陶宛最大医疗机构中对潜在器官供体库的影响。在 LSMU 考纳斯临床医院建立了器官捐献协调员服务,并实施了主动寻找 DBD 的策略,对 2016 年 12 月至 2017 年 12 月期间的数据进行了回顾性分析。收集的数据与同中心前一年的可用数据和全国捐赠动态进行了比较。所有重症监护病房(ICU)共收治 6734 例患者,其中 234 例(3.5%)被确定为可能的供体。与前一年( = 37)相比,研究年度( = 34)潜在供体数量没有增加。潜在供体的人口统计学数据、死亡原因、家属拒绝和医学禁忌症发生率无显著差异。对 20%的潜在供体重复进行脑血管造影(CA)以确认脑死亡诊断。重复 CA 的潜在供体中,行减压性颅骨切除术的比例更高(66.7%比 33.3%, = 0.018)。减压性颅骨切除术统计学上显著增加了重复 CA 的发生率(OR 12.7;95%CI,1.42-113.37; = 0.023)。与前一年相比,主动搜索策略使潜在供体的住院时间延长(3.97 ± 4.73 比 2.51 ± 2.63, = 0.003)。本研究期间观察到,在住院的头四天内是识别潜在供体的最佳时间(OR 10.42;95%CI,4.29-25.34; = 0.001)。尽管在短短的一年时间内,我们无法证明主动供体识别策略优于被动策略的优越性,但在实验性供体中心,在国家供体数量减少的情况下,我们获得了关于脑死亡诊断的宝贵知识,采用了新的术语,并观察到实际供体数量的稳定性。需要制定长期战略,以在器官捐赠方面取得可持续成果。
