RESUMO

OBJECTIVES: Although livers from older donors (> 70 y) have been shown to be increasingly more efficiently used for transplant, donor comorbidities are considered additional risk factors. This is quite intriguing as comorbidities are known to increase with advancing age in the donor population. MATERIALS AND METHODS: We assessed whether age and donor comorbidities influenced liver procurement over a 15-year period in a cohort of 1702 brain-dead donors in Tuscany, Italy. RESULTS: Over the study period, age of potential donors significantly increased (P = .02) as well as the proportion of patients who were > 55 years old. The incidence of hypertension, diabetes mellitus, and previously known coronary artery disease also significantly increased. We observed a progressive increase in the number of transplanted livers from donors with advancing age despite an increase in comorbidities. The highest incidences of traumatic brain injury and anoxic brain injury were observed in the youngest donors. Transaminase levels and use of vasoactive drugs were lower in donors who were ≥ 72 years old. CONCLUSIONS: According to our results, criteria for liver donors have already changed. Although age does not seem to be a limiting factor, older donors deserve a more accurate donor selection due to the higher incidence of risk factors (primarily diabetes mellitus).

RESUMO

Changes in the causes of brain death may influence the numbers of hearts that can be procured and transplanted. We retrospectively investigated whether the distribution of causes responsible for brain death have changed over a 15-year period in a cohort of 1286 potential heart donor (aged ≤ 60), and whether it influenced heart procurement. Between 2001 and 2016, the age of potential donors significantly increased (p < 0.0001) as well as the relative proportion of postanoxic brain death, while that of traumatic brain injury decreased (p = 0.0007). A significant increase in the use of norepinephrine was detectable. The number of transplanted hearts did not significantly change, with no differences in the age of donors or in the causes of brain death. According to our data, in our 15-year study period, significant changes in the causes of brain death occurred (indicated by a reduction in potential donors following traumatic brain injury) together with an increase in donor age. Nevertheless, the number of transplanted hearts did not change probably thanks to a modified donor management (as inferred by a different use of vasoactive drugs).

RESUMO

BACKGROUND: Family refusal (FR) to heart beating donation (HBD) in Intensive Care Unit (ICU) is increasing in recent years with a significant impact on the number of transplantable organs. Fostering setting humanization, quality of relationships, respect for will and family reliance towards ICU could be relevant in containing FR to organ donation (OD) in ICU. Our aims were to highlight the effects of structural features of ICUs and humanization determinants on FR in HBD process, and to describe visiting policies, structure and modalities of support in ICUs. METHODS: A survey was conducted among all the ICUs of the Tuscany Region included in the National Transplant System of the Ministry of Health in Italy. Data on ICUs' general and architectural characteristics, visiting policies and support for families were collected. Baseline characteristics of brain dead certified patients (BDCPs) were retrieved from the Registry of the Regional Transplant Centre. RESULTS: Twenty-nine (93.5%) ICUs out of 31 completed the survey. 330 BDCPs were managed during 2016 in the ICUs studied, with an opposition rate of 33.3%. The following independent factors for opposition emerged: BDCPs' age (OR=1.025; 95% CI: 1.007-1.042; P=0.005), ICU length of stay (LOS) (OR=1.065; 95% CI: 1.005-1.128; P=0.034) and the availability of an ICU team trained in procurement (OR=0.472; 95% CI: 0.275-0.811; P=0.007). CONCLUSIONS: Older age of BDCPs and a prolonged ICU LOS resulted in FR. ICU team specific education emerged as the only modifiable protective factor for oppositions, thus continuous and in-depth training programs for physicians and nurses could be of importance in preventing FR.
