Public perception and misperceptions of socioeconomic disparities affect the willingness to donate organs. To improve our understanding of the flow of deceased donor kidneys, we analyzed socioeconomic status (SES) and racial/ethnic gradients between donors and recipients. In a retrospective cohort study, traditional demographic and socioeconomic factors, as well as an SES index, were compared in 56,697 deceased kidney donor and recipient pairs transplanted between 2007 and 2012. Kidneys were more likely to be transplanted in recipients of the same racial/ethnic group as the donor (p < 0.001). Kidneys tended to go to recipients of lower SES index (50.5% of the time, p < 0.001), a relationship that remained after adjusting for other available markers of donor organ quality and SES (p < 0.001). Deceased donor kidneys do not appear to be transplanted from donors of lower SES to recipients of higher SES; this information may be useful in counseling potential donors and their families regarding the distribution of their organ gifts. 相似文献

The new national Kidney Allocation System of the Organ Procurement and Transplantation Network (OPTN), effective as of December 4, 2014, was designed to improve the chances of transplanting the most highly sensitized patients on the waitlist, those with calculated panel reactive antibody values of 98%, 99% and 100%. Recently, it was suggested that these highly sensitized patients will experience inequitable access, given the reported high prevalence of antibodies to HLA‐DP, and the fact that only about 1/3 of deceased donors are typed for HLA‐DP antigens. Here we report that 320/2948 flow cytometric crossmatches performed for the Northwestern transplant program over the past 28 months were positive solely due to HLA‐DP donor‐specific antibodies (11%; 16.5% of patients with HLA antibodies—sensitized patients). We further show that 58/207 (12%) HLA‐DR serologically matched donor‐recipient pairs had a positive B cell flow crossmatch due to donor‐specific HLA class II antibodies, and 2/34 (6%) serologic zero‐HLA‐A‐B‐DR mismatch had a positive flow crossmatch due to HLA‐DSA. We therefore provide information regarding the necessity and importance of complete donor HLA typing including both chains of the HLA‐DP antigen (encoded by HLA‐DPA1 and HLA‐DPB1) at the time of organ offer. 相似文献

Objectives
To describe the profile of patients evaluated by Nurse Care Management in an Emergency Department and identify the type of alternative healthcare resource assigned and report the results of clinical practice.Material and methods
Prospective follow-up, on admission to the Emergency Department in an acute hospital and on discharge from the alternative healthcare resource, of patients assessed by Nurse Care Management, from July to December 2015. The patient characteristics, social environment and results of clinical practice were studied.Results
190 patients were included of whom 13 were readmitted (6.8%). 122 (59.8%) cases from the Emergency Department were referred to to intermediate care facilities, 71 (34.8%) cases for domiciliary care, 10 (4.9%) cases were referred to an acute care hospital and 1 (0.5%) died. Patients referred to intermediate care were more complex, presented geriatric syndromes as their reason for admission and diagnosed with dementia, while those referred to home care presented more respiratory and cardiovascular illnesses (p <0.05). The mean Barthel Index and polypharmacy before emergency admission were higher than at the time of discharge from the alternative healthcare resource (p <0.05).Conclusions
Patients presenting with advanced age, complexity, comorbidity, are referred to intermediate care facilities or domiciliary care, they are admitted to acute care hospitasl and are readmitted less than other patients. After being discharged from the alternative resource, they lose functional capacity and present less polypharmacy. 相似文献1000.
