Abstract
Previous studies have identified healthcare practices that may place undue pressure on related donors (RDs) of hematopoietic cell products, and an increase in serious adverse events associated with morbidities in this population. As a result, specific requirements to safeguard RD health have been introduced to FACT-JACIE Standards, but the impact of accreditation on RD care has not previously been evaluated. A survey of transplant program directors of EBMT member centers was conducted by the Donor Health and Safety Working Committee of the Center for International Blood and Marrow Transplant Research (CIBMTR) to test the hypothesis that RD care in FACT-JACIE accredited centers is more closely aligned with international consensus donor care recommendations than RD care delivered in centers without accreditation. Responses were received from 39% of 304 centers. Our results show that practice in accredited centers was much closer to recommended standards as compared to non-accredited centers. Specifically, a higher percentage of accredited centers use eligibility criteria to assess RDs (93% versus 78%; P=0.02) and a lower percentage have a single physician simultaneously responsible for a RD and their recipient (14% versus 35%; P=0.008). In contrast, where regulatory standards do not exist, both accredited and non-accredited centers fell short of accepted best practice. These results raise concerns that despite improvements in care, current practice can place undue pressure on donors, and may increase the risk of donation-associated adverse events. We recommend measures to address these issues through enhancement of regulatory standards as well as national initiatives to standardize RD care.

Introduction
Current data suggest that the incidence of donation associated adverse events, including death, is higher in related donors (RDs) than UDs.1 This is particularly true of RDs who do not meet unrelated donor (UD) suitability criteria, yet relatives donating hematopoietic progenitor cells (HPCs) are frequently permitted to proceed with morbidities for which an UD would be deferred.2-4 This inequality in practice occurs due to several key differences between the care of UDs and RDs, including a lack of regulatory guidance in the RD setting, and logistical or financial barriers.
In the UD field, the recognized need to both ensure the safety of stem cell products for recipients internationally, and to protect volunteer donors, led to foundation of the World Marrow Donor Association (WMDA) in 1988 as a global organization providing regulation and guidance for HPC donor registries. WMDA Standards5 attempt to minimize coercion of UDs through the requirement that the medical team providing their care will have no involvement in the care of their recipient, and by preserving anonymity throughout the donation process. To safeguard UD health, donors are automatically deferred if they do not meet clear suitability criteria against which they are assessed at three stages: recruitment, verification typing and a formal donor medical assessment.6 Information about donation is provided at each of these stages, which are often months or years apart in time, ensuring longstanding motivation to proceed with donation.
The situation for related donors (RDs) is more complex. They lack the benefit of anonymity and, as a result of historical care pathways, almost invariably donate at the same transplant center treating their relative. The intimacy of their relationship with the transplant recipient may yield feelings that translate to an internal pressure to donate, including the desire to help their sick relative, a sense of duty or even guilt.7,8 RDs are also vulnerable to experiencing additional pressure to donate from external sources, such as their relatives, or members of the healthcare team caring for their potential recipient. Furthermore, RD tend to be older than UDs, and are more likely to have morbidities, which they may underplay in view of their motivation to donate.
Previous investigations have raised concerns that practice in Europe does not sufficiently protect RDs from experiencing undue pressure. This issue was first addressed in a study conducted by the European Group for Blood and Marrow Transplantation (EBMT) Nurses Group/Late Effects working party.9 Sixty-three nurses, delegates at the 2005 EBMT annual meeting, completed questionnaires regarding the counseling, consent and follow up of RDs at their centers. Findings suggested large variation in donor counseling practices; only 25% of responding nurses indicated that RDs were consented by a physician who was not involved in the care of their recipient Furthermore, they showed that in in 11% of centers the donor's HLA results would be first disclosed to their recipient breaching confidentiality and potentially pressuring the donor to proceed. A survey of US transplant center directors in 200710 reported a potential conflict of interest in >70% of centers, where the same physician caring for the donor had either simultaneous responsibility for, or might be involved in the care of, the recipient. In 2012, an analysis of the care of 500 related donors in Italy 11 further highlighted issues with overlapping donor/recipient care and showed that only 26% of donors underwent thorough screening according to Italian Bone Marrow Donor Registry standards.
A few recent consensus statements have offered guidance around RD care. In 2010, a WMDA working group published recommendations for family donor care12 focusing on appropriate counseling and assessment prior to HLA typing, avoidance of conflict of interest by care providers and RD follow-up. In 2013, a Worldwide Network of Blood and Marrow Transplantation (WBMT) consensus paper advocated standardized assessment of donor outcome with a minimum data set.13 The Joint Accreditation Committee ISCT and EBMT (JACIE)/Foundation for the Accreditation of Cellular Therapy (FACT) has also introduced specific standards to address some of these issues, including donor evaluation criteria, a donor follow up policy and the requirement that “Allogeneic donor suitability should be evaluated by a physician who is not the physician of the recipient.”14 In many European countries, however, accreditation is not mandatory for centers assessing RDs, and no studies to date have investigated the impact of accreditation on practice patterns in RD care.
We hypothesized that adult RD practice remains heterogeneous, and is more likely to mirror UD care in accredited than in non-accredited transplant centers. To test this hypothesis, we conducted a survey of EBMT transplant center directors, designed to assess areas of care addressed by the 2005 survey, and additional areas where clear UD standards exist, but which are not yet embedded in regulatory guidance for RDs.
Materials and methods
A 38-item survey was developed to examine related donor care practice (see Supplementary Appendix). Questions were designed to determine center adherence to 5th JACIE Standards,14 to WMDA recommendations for RD care15 and to WBMT donor follow up recommendations13. The survey was administered as an internet-based questionnaire via a secure hyperlink (surveymonkey.com) from August to November 2014. Program directors of all US transplant centers reporting data to CIBMTR and all EBMT allogeneic transplant member centers received an email invitation to participate, with a request to forward the survey to the physician responsible for RD care. UK centers, where a very similar survey had recently been conducted, were excluded. Entry into a drawing for a free CIBMTR/ASBMT Tandem Annual Meeting registration was offered as an incentive to increase the response rate. All procedures were reviewed by the NMDP Institutional Review Board, This study was also approved by the Donor Outcomes Committee of the EBMT, whose mailing list was used to contact EBMT centers.
Due to differences in practice, the results from CIBMTR and EBMT centers were analyzed separately. The EBMT center data is presented in this manuscript.
In view of known differences between adult and pediatric RD care (due to the requirement for a donor advocate in the pediatric setting by EU Directive 2004/23/EC), this study focused purely on the care of adult RDs. The survey invitation specified that the study referred to the care of adult related stem cell donors only, and the survey terminated if respondents answered ‘no' to the first question “Does your center perform allogeneic HPC transplants from adult (>18 years old) related donors?”.
Following the initial invitation, non-responders received three further email reminders. Where greater than one response was received from a center, the most complete was used for analysis. Four responses were excluded from analyses because they stated they did not perform allogeneic transplants using related donors >18 years of age. Data were not available to determine the number of non-responding centers performing purely pediatric transplants that would therefore have been ineligible for the study.
Centers were grouped by size in the analysis defined as the number of first allografts performed per year. These data were collected from EBMT activity survey.16 Centers were also grouped according to their geographical location including Eastern Europe; Northern; Southern Europe; Western Europe and Non-European Nations. To minimize ‘drop-outs' from the survey, the set-up allowed participants to skip questions, however results were only analyzed and presented for questions that >80% of responding centers had completed. Statistics were performed using SPSS software (version 22.0; SPSS, Chicago, IL). Relationships between categorical center characteristics and response rate or adherence to standards were examined using Chi squared or Fisher's exact test where appropriate. All variables found to be significant in univariate analyses were included in a multivariable stepwise logistic regression analysis.
Results
Response rate
Excluding duplicates, 118 eligible responses were received from 304 centers, a response rate of 39%, with a significantly higher response rate in FACT-JACIE accredited compared to non-accredited centers (52% versus 33%; P=0.001). Overall 59/118 (50%) responding centers had FACT-JACIE accreditation. As shown in Figure 1, no consistent pattern in response rate by center size was observed. The median number of first allografts per year in responding centers was 23 (range 1-172). As shown in Figure 1B, no significant difference in response rate was observed between geographical regions (P=0.151).
The impact of FACT-JACIE accreditation on practice
We found multiple significant practice differences between accredited and non-accredited transplant centers (shown in Table 1). Across key indicators, practice in accredited centers was more likely to conform to international consensus recommendations than that in non-accredited centers. As expected, this difference was particularly evident in those areas of care addressed by current FACT-JACIE Standards, where accredited centers were far more likely to conform to the recommendation. Accredited centers were significantly more likely to have a policy for RD care (98% versus 83%; P=0.004), to use defined eligibility criteria to assess RDs (93% versus 78%; P=0.02), and to have a process for credentialing physicians performing BM harvests (86% versus 63%; P=0.008).

As shown in Figure 2, medical clearance of related donors was undertaken by transplant physicians in 45% of accredited and 69% of non-accredited centers (P=0.036) and overall a quarter of centers failed to comply with the FACT-JACIE requirement that the donor's physician should not be simultaneously responsible for the recipient. This practice of overlapping care occurred more frequently in non-accredited centers (14% accredited, 35% non-accredited; P=0.008).
We examined areas of care outside the remit of current (5th) FACT-JACIE Standards, but where international consensus recommendations or standard UD practices offer a benchmark. Here we found that accredited centers more frequently complied with several recommendations, including that they were less likely to first disclose the donor's HLA results to an individual other than the donor themselves (61% versus 86%; P=0.007). We asked whether centers had used plerixafor as a mobilizing agent in related donors, and found that a significantly higher proportion of non-accredited centers had done so (20% accredited versus 38% non-accredited; P=0.032). As shown in Figure 3, 89% of the centers described a follow up program, which continued beyond one-year post donation in over two thirds and up to 10 years in 20% of centers. Although accreditation did not impact the likelihood of providing a follow up program, the accredited centers more frequently adhered to WBMT recommendations for 10-year donor follow up (34% versus 14%; P=0.05).
We found other areas of practice not addressed by FACT-JACIE Standards, in which both accredited and non-accredited centers did not follow international guidelines. Care prior to HLA typing was markedly inconsistent with recommendations on family donor care management produced by a subgroup of WMDA,15 and to UD norms, with 40% of respondents indicating that no assessment of donor health is made prior to HLA typing and a quarter failing to verify that donors are willing to donate at this point. There was a trend towards accredited centers being more likely to supply donors with written information prior to HLA typing, which occurred in 55% of accredited and 45% of non-accredited centers (P=0.073).
A trend was also observed towards accredited centers being more likely to have a policy defining a limit to the number of apheresis procedures a donor could undergo during their initial donation (72% versus 55%; P=0.057), but no impact was observed on the likelihood of a policy defining BM harvest limits, which existed in 66% of centers. Where details on these harvest limits were given, they were in line with UD policies in nearly all cases.
Centers performing fewer than the median 23 allogeneic HCTs per year were less likely to be accredited than higher volume centers, however, center volume did not significantly impact any practice parameters in multivariate analysis.
Discussion
These results provide unique insights into RD care in EBMT transplant centers, and the impact of FACT-JACIE accreditation in this field. We found better compliance with internationally recognized donor care paradigms in centers with FACT-JACIE accreditation, but crucially also found important practice gaps in all centers irrespective of accreditation.
We were unable to obtain information regarding which centers were purely pediatric, and all EBMT centers were therefore invited to complete the survey. Thus, although the response rate was relatively low at 39%, it is likely that ineligible pediatric centers comprised many of the non-responding centers.
Although our study differed from the earlier survey conducted by the EBMT Nurses Group/Late Effects working party,9 it is nevertheless possible to draw several robust conclusions about progress over the nine years between studies. Firstly, only 25% of respondents in the earlier survey stated that RDs were consented by a physician not involved in recipient care. Although not a direct comparison, we show here that in 75% of centers the physician providing medical clearance of the RD was not routinely responsible for the care of the recipient. Secondly, donor follow up has become more prevalent, with 89% of responding centers now providing a follow up program compared to 60% in 2005. This may in part be attributable to the development of a system for centralized reporting for related donor outcome data by the EBMT donor group, in addition to national regulations mandating follow up in some countries.
Despite this progress, we identified several stages of the RD care pathway where practice continues to put the donor's health and autonomy at risk, and we urge RD care providers to consider the following issues. In >40% of centers no assessment of donor health is made prior to HLA typing, thus a donor's medical issues will not be identified until the formal donor medical assessment, shortly before donation. This practice may lead to donors' purposefully or inadvertently failing to disclose medical issues during the subsequent medical assessment (and in doing so putting themselves – and potentially the recipient - at risk when donating), or being cancelled at the point of donor medical clearance, incurring a potentially critical delay in the recipient's HCT. Furthermore, >70% of centers breach confidentiality by first disclosing the donor's HLA matching status another individual, a practice that potentially places undue pressure the donor to proceed, since he/she cannot then decline to donate without potential repercussions on their relationship with the recipient. Lastly, we hope to see a further reduction in the practice of routine overlap of recipient and donor care following introduction of 6th edition of FACT-JACIE standard where the recommendation for divided responsibility for donor and recipient care in the previous standard's edition has now been changed to a requirement.
Another important finding of this survey is the fact that off-label plerixa for has already been used in related donors by a considerable number of centers. Hence there is an urgent need to register and follow these donors to analyze long-term safety of this and other new drugs to come.
There are compelling reasons to address these issues. Potential related donors are identified by their sick relatives, unlike UDs who are anonymous. It will never be possible to eliminate the pressure to donate; therefore policies to minimize this are crucial. Transplant physicians undertake most aspects of RD care in over 80% of centers, and major changes would be required to have a separate team assume responsibility for RDs. If independent donor care is not feasible, clear policies to avoid conflicts of interest and protect donor health should be implemented, such as mandating a donor advocate be involved in the process. Several issues we identify here could be addressed by simple changes to current procedures without significant cost implications, for example ensuring that HLA matching status is disclosed to the donor first, with permission required before disclosure to another party. Similarly, comprehensive information about the donation process could be provided, and a health assessment completed in advance of HLA typing, possibly over the phone or via email as per successful UD registry practice.
The improvements in donor care that we show have specifically occurred in areas where recent FACT-JACIE standards were introduced, confirming the impact of quality management in driving change. A similar effect of FACT-JACIE accreditation on allogeneic HCT patient care has been recently demonstrated, with substantial stepwise improvements in long and short-term patient outcomes with each step of the process towards accreditation in EBMT transplant centers.17
In some countries, transplant centers (TCs) are obliged to conform to accreditation, but this is not universally the case in Europe, where >50% of TCs are not accredited. We encourage non-accredited centers to adopt regulatory guidance around RD care, but other approaches must also be considered, particularly the creation of evidence based RD care guidelines at a national or international level. The WBMT donor issues committee is developing eligibility guidelines for assessment of related donors who do not meet suitability criteria for UDs, an area in which guidance to safeguard RD health is much needed. UD registries have a wealth of experience in donor care and could also facilitate improvements in the RD field either by sharing donor information resources with TCs, or, in some countries, through national initiatives to improve donor follow up.
The continuing increase in haploidentical transplantation raises several questions for the future of RD care, including whether transplant centers have the provision for performing increasing volumes of time consuming assessments. In addition, most studies to date investigating RD experience and psychological outcomes are based on sibling donors, and the dynamics of, for example, a parent/child relationship are different and require additional consideration.18 This survey focused on determining the current status of adult RD practice in EBMT centers, similar studies investigating pediatric practice are needed. Exploring the perceptions of transplant physicians regarding the barriers to providing optimal care would be helpful to determine how to best realize improvements, which would likely best be driven by further augmentation of FACT-JACIE Standards.
