Introduction

Allogeneic hematopoietic cell transplant (HCT) is increasingly used as a curative option for children and adolescents with malignant and non-malignant hematologic conditions [1]. However, it is also an intense process during children’s formative years and negatively impacts their physical, emotional, and socio-environmental domains of quality of life (QOL) [2]. Pediatric HCT recipients remain out of school for a prolonged period of time during their treatment course and recovery, and in part due to their immune compromised status and potential risk of infections [3, 4]. Returning to school post-HCT is an important milestone for survivors as it provides a sense of normalcy, a self-esteem boost, and social support while they cope with treatment-related toxicities [5]. School also provides an essential framework for social, intellectual, and academic development of children and is critical to obtain the skillsets necessary to enter higher educational training and/ or the workforce. Therefore, early school reintegration could be potentially beneficial for HCT survivors, despite the current literature lacking data on recommended timing of return to school post-HCT for survivors.

Educational disruption is commonly seen while patients undergo peri-transplant hospitalization [6, 7], and returning to school after prolonged absence(s) can be challenging for patients and caregivers. Literature thus far has been predominantly focused on the school and educational challenges of childhood and adolescent cancer survivors treated with conventional (non-HCT) therapy, including physicians’ perspectives on the return to school process after completion of therapy [8,9,10]. However, patients receiving HCT have prolonged hospitalizations and their therapy results in prolonged and severe immune deficiency. For this reason, return to school guidance in HCT patients must be considered differently from their oncology peers. Unfortunately, information by HCT physicians on how HCT centers provide support for the return to school process is lacking.

To address the knowledge gap, our primary aim was to assess the availability of any standardized operating procedure (SOP) documents at HCT centers to guide physicians regarding autologous and allogeneic HCT recipients’ return to school in a traditional classroom setting. Additionally, we aimed to identify inter-physician practice variations in guiding HCT recipients when to return to school and factors associated with their decision-making process.

Materials/ subjects and methods

This study was approved by the National Marrow Donor Program (NMDP) Institutional Review Board. We conducted a two-phase cross-sectional web-based survey of HCT physicians in the United States (US) through the Center for International Blood and Marrow Transplant Research (CIBMTR) Health Services Research Program. The overall survey development and dissemination plan is shown in Fig. 1. The surveys were developed in consultation with content experts in pediatric HCT and health services research. In Phase I, medical directors of pediatric HCT programs listed in the NMDP/ Be The Match Registry were approached between January and February 2020 by email to answer a single question evaluating the existence of an SOP advising physicians when to recommend autologous and allogeneic HCT recipients should return to school after HCT (Supplemental File: Appendix A). The centers that reported having a SOP were requested to provide a copy of the SOP as able to share. In Phase II, pediatric HCT physicians identified through the Pediatric Transplantation and Cellular Therapy Consortium (PTCTC) membership directory were approached to study: (1) inter-physician practice variability within and across transplant centers to guide patients regarding when to return to in-person school post-HCT; (2) factors considered before a patient’s return to in-person school; and (3) topics addressed to help with survivors’ return to school. Additionally, demographics of HCT physicians, such as age, sex, and years of experience, were collected. The Phase II survey was initially piloted with three pediatric HCT experts before its dissemination. These physicians were excluded at the time of the survey dissemination. Similar to Phase I, HCT physicians were approached by email to fill out a web-based survey between December 2020 and January 2021. In Phase II, HCT physicians answered up to a maximum of 22 questions (Supplemental File: Appendix B). An additional questionnaire to understand return to school practices during the Coronavirus disease-19 (COVID-19) pandemic was also offered to HCT physicians during Phase II, results of which have previously been published [11]. Both phases of the survey were hosted by Alchemer (Louisville, CO), a secure online survey platform. Weekly follow-up emails were sent after the initial survey was sent in both phases.

Descriptive analysis of survey data was performed, noting the frequency and percentages of survey responses. The answers were stratified by physicians’ demographic characteristics available through the survey and transplant center characteristics, such as location and average number of transplants performed per center as available through the CIBMTR.

Results

Phase I

Of 84 total pediatric HCT centers, 46 HCT center directors responded to Phase I (55% response rate). Twenty-eight (61%) reported having an SOP advising clinicians practicing at the transplant centers regarding return to school timing and decision-making for HCT recipients. Twelve SOPs (43%) were received and reviewed. The details of SOP responses are provided in Table 1. Wide variations existed in the recommendations regarding the need for specific assessments prior to return to school, the acceptable extent of immune suppression, and overall timing.

Table 1 Return to school SOPs provided by HCT center directors.

Half of the centers (n = 6) recommended immunologic assessment prior to return to school. Specifically, Centers 6, 7, 11, and 12 recommended certain levels for absolute neutrophil count, absolute lymphocyte counts, and/ or CD4 T-lymphocyte counts; however, thresholds for these parameters differed. Five of the responding centers (42%) also recommended the initiation of re-immunization as one of the criteria for return to school. Additionally, Center 8 recommended assessing a response to mitogen & antigen-stimulated lymphocyte proliferation. Only one of the responding centers (Center 9) reported assessing physical and psychosocial readiness prior to return to school. Eight centers (67%) documented recommendations regarding the acceptable extent of immune suppression prior to return to school in their SOPs. Centers 11 and 12 required that allogeneic HCT recipients be off all immune suppression, while Centers 6 and 7 allowed allogeneic HCT recipients to return to school with tapering immune suppression, and Centers 8 and 10 were comfortable with allogeneic HCT recipients returning to school as long as graft vs. host disease (GVHD) was not active and/ or uncontrolled, which was defined by Center 10 as requiring greater than 0.5 mg/kg/day of prednisone or ≥2 lines of immunosuppressive therapy. Five of the SOPs (42%) provided predominantly timing-based return-to-school guidance; the recommended timing for return to school varied between 3 and 12 months for autologous HCT recipients and between 6 and 12 months for allogeneic HCT recipients. Center 2 recommended return to school at 1-year post-HCT for allogeneic HCT recipients even if they were on immune suppressive therapy.

Phase II

In Phase II, 122 HCT physicians from 60 HCT centers responded to the survey (30.6% response rate) between December 14, 2020, and January 1, 2021. Table 2 shows the characteristics of the study population. Fifty-five percent (n = 67) of the respondents were females, and 70% of physicians had more than ten years of experience. Respondents practiced across 32 states of the US with equal representation from Midwest (28%), South (28%), West (24%), and Northeast (20%) regions. Sixty-eight percent (n = 83) practiced at HCT centers that, on average, performed up to 60 transplants per year.

Table 2 Characteristics of Phase II survey respondents (N = 122).

Regarding recommended timing of return to school, variations in inter-physician practice were noted (Fig. 2). The majority (60%) of respondents recommended that recipients of autologous HCT should return to school within 6 months post-HCT. For allogeneic HCT recipients, 65% recommended returning to school only after 6 months post-HCT or once off immune suppression. A lack of consensus was noted regarding the timing of return to school between HCT physicians practicing at the same center. When restricting the analysis to centers with more than one respondent (n = 29 centers), physicians from only four centers (14%) showed agreement in recommended return to school timing. In the remaining centers, inter-physician practice variability was evident regardless of the availability of SOP (Fig. 3a, b).

When asked about the timing of the first detailed discussion regarding return to school with HCT recipients and/or caregivers, 65% of HCT physicians reported having their first detailed discussion with autologous HCT recipients and/or caregivers within 6 months post-HCT. In comparison, only 42% of respondents reported having the discussion with allogeneic HCT recipients and/or caregivers within 6 months post-HCT, but 77% had the discussion by 12 months post-HCT. Next, we asked participants how the return to school information is provided to HCT recipients and/or caregivers. Respondents stated that the discussion with a physician (92%) or advanced practice provider (61%) were the most common sources of return to school information delivery. Discussion with a physician remained the most common form of information delivery regardless of respondents’ age, sex, year of experience, HCT center location, or average number of transplants performed.

We also asked participants about the factors considered by them before recommending when HCT recipients should return to school post-HCT. The top three factors taken into consideration by physicians were ongoing health complications (88%), disease status (61%), and primary oncologist’s preference (47%) for autologous HCT recipients and GVHD or immune suppression (93%), immune reconstitution (89%), and ongoing health complications (87%) for allogeneic HCT recipients. Again, these findings remained consistent when stratified by the physician and center characteristics. Next, we asked physicians what topics are addressed by the HCT centers in preparation of a recipient’s return to school. Eighty percent of respondents reported addressing the need for an individualized education plan/ 504 plan prior to HCT recipients’ return to school post-HCT, whereas 75% reported addressing the need for homebound schooling/ tutoring. Physicians aged 41–50, from mid to large-size programs (averaging >25 transplants per year) and having 11–20 years of experience also reported directly communicating with school officials.

Lastly, we asked physicians to respond to five questions on a Likert scale ranging from strongly agree to strongly disagree. Overall, more than half of the respondents either agreed or strongly agreed that return to school is difficult for patients post-HCT (75%), physical demands make a return to school difficult for patients post-HCT (63%), emotional distress makes return to school difficult for patients post-HCT (67%), cognitive concerns make return to school difficult for patients post-HCT (63%), and lack of support from school and/or other students make return to school difficult for patients post-HCT (57%).

Discussion

To our knowledge, this is the first study to describe the current pediatric HCT center practices and HCT physicians’ perspective on return to school after HCT. While three-quarters of the respondents stated that returning to school after HCT can be challenging for survivors, we noted a limited availability of standardized return to school recommendations within HCT centers. The existing recommendations varied in terms of timing and criteria for returning to in-person school. We also found a significant heterogeneity in return to school timing recommended by HCT physicians practicing at the same center regardless of the availability of standardized guidelines. Additionally, variations in factors affecting physicians’ decision-making and the type of support provided by HCT centers were also noted.

Majority of survey respondents felt that the process of returning to school can be challenging for HCT recipients, which is consistent with the prior studies that have assessed school and educational challenges in HCT survivors [7, 12,13,14,15]. Despite this evidence, return to school support was not consistently provided by physicians as reported in our analysis. Additionally, there is a limited availability of online resources from national organizations to guide HCT recipients, caregivers, and healthcare and school professionals regarding the return to school process [16]. In contrast, organizations such as the American Cancer Society and Leukemia & Lymphoma Society have developed materials to educate patients and caregivers, and other involved stakeholders regarding the return to school process for cancer survivors after completion of therapy [17,18,19]. It is known that HCT survivors are at a higher risk of chronic health conditions and worse QOL compared to childhood cancer survivors treated with non-HCT therapy, likely due to their exposure to prolonged immune suppression and the cumulative impact of treatment exposures prior to and during HCT [20]. These data along with our study findings emphasize the importance of providing better return to school guidance to HCT recipients.

The significant variations in the return to school guidance noted in our analysis likely stems from the lack of evidence-based data on this topic among HCT survivors. Several centers recommended assessments related to immune reconstitution prior to return to school, however, it is unclear whether they are based on any evidence. Prior studies have shown that HCT recipients remain at a higher risk of infections compared to cancer survivors treated with non-HCT therapy and general population even beyond 2 years post-HCT [21], albeit, it is unclear how these risks have changed with improvements in supportive care and use of antimicrobial prophylaxis. Additionally, chronic GVHD and ongoing immune suppression are known risk factors for fatal infections [22]. On the contrary, from the studies focusing on childhood cancer survivors, it is also evident that extended school absences could significantly impact survivors’ their academic attainment, their future employment opportunities, and become productive members of the society [23, 24]. Therefore, these data warrant serious consideration of school reintegration benefits in relation to the infection risks. While our study findings provide valuable information to HCT physicians regarding the current return to school practices across the country, given the wide variations in timing, assessments, and support, it does not help fill the unmet need. However, our study findings provide an opportunity to highlight the potential implications of variations in return to school practices at patient- and caregiver-, other stakeholder-, and center-level, which could further emphasize the importance of having standardized return to school practices across the country.

While our current analysis did not focus on the perspectives of patients and caregivers on the return to school practices, we recently performed a single center qualitative analysis of HCT recipients and their caregivers to understand the barriers and facilitators of return to school process after HCT [15]. Availability and lack thereof communication and coordination from both healthcare and school professionals were reported as facilitators and barriers for the return to school process, which highlights the significant burden from return to school practice variations on caregivers. Caregivers also recommended having direct communication between family, school, and healthcare professionals prior to return to school and having a point of contact (return to school navigator) to improve the process for future patients [15], which aligns with the recommendations provided through the psychosocial standard of care [25].

Our findings have several implications on clinicians as well. Our analysis noted that HCT physicians play an important role in the return to school process since they reported being primarily responsible for providing schooling information to patients and families. This finding is consistent with another cross-sectional survey of pediatric oncologists practicing at Children’s Oncology Group member institutions [8]. This survey was primarily focused on assessing physicians’ knowledge and training regarding cognitive and school-related challenges faced by childhood cancer survivors. The authors found that more than half of the physicians reported receiving no training, and two-thirds somewhat understood the return to school challenges faced by childhood cancer survivors. While the majority of HCT physicians in our analysis agreed that return to school process could be challenging for HCT survivors, our survey lacked information on their knowledge and training regarding the return to school process. Future work aimed towards understanding and improving HCT physicians’ understanding of HCT survivors’ return to school challenges would be beneficial.

Return to school is a complex process, and support from all stakeholders, including healthcare professionals and school professionals, is required for a successful return to school experience. While the respondents reported addressing several of the key topics, such as the need for an individualized education plan, homebound schooling, and gradual return to school approach, variations in available support were noted with low volume centers (≤25 procedures per year) reporting a lesser return to school support compared to higher volume centers. Additionally, physicians were less likely to address the need for physical or occupational therapy and discussion of legal rights related to school services. Only 65% of respondents reported direct communication with school officials prior to survivors’ return to in-person school. School professionals play an important role in the return to school process, and prior studies focusing on the return to school of childhood and adolescent cancer survivors treated with conventional (non-HCT) therapy have reported significant challenges related to limited communication between healthcare professionals and school officials [8,9,10]. These findings provide a potential opportunity to improve communication between all involved stakeholders.

The inconsistent availability of and variability in return to school SOP also highlights the importance of improving return to school process at the HCT center level given the potential impact on quality of care. There is a growing need for quality improvement in the field of HCT and cellular therapy to improve both short- and long-term outcomes [26]. At the center level, the process could possibly be improved using the Model for Improvement methodology, which includes rapid PDSA (Plan, Develop, Study, and Act) cycles to improve the process. On a broader scale, the use of learning health networks could also be considered, which include healthcare professionals, researchers, patients, and caregivers with a common goal of driving innovation and improving outcomes through sharing knowledge in real time and solving complex problems [27].

Based on the findings from our study and their potential implications, as a next step, we envision development of standardized return to school guidelines. Such effort would require involvement of all stakeholders (physicians/ advance practice providers specializing in HCT and infectious diseases, with content specific expertize, nursing, social workers, psychologists, educators, and HCT recipients/ caregivers) to develop evidence or consensus-based recommendations for return to school timing, assessments, and support. Similar work was recently completed for the return to work process for HCT recipients with the support of the American Society of Transplantation and Cellular Therapy [28]. Similar to the effort to improve the return to work process post-HCT, the development of standardized return to school guidelines would also require a thorough literature search on all relevant aspects of this topic. Subsequently, using the evidence as per available literature and expert-opinion based guidance, the recommendations should be made regarding the ideal timing of return to school post-HCT considering the risks and benefits, optimal assessments to understand survivors’ readiness to return to school from physical, psychological, and neurocognitive perspective, and type of support that should be provided to patients and caregivers prior to school reentry. In addition to the development of the guidelines, it would be equally important to ensure its dissemination to all stakeholders such as having patient and caregiver facing resources, practical checklists for healthcare professionals, educational materials for school professionals and classmates, and online resources from national organizations directed towards all stakeholders. Lastly, emphasis should also be placed on ongoing evaluations to assess and ensure its uptake. Table 3 provides an outline of the proposed process of standardizing the return to school process for HCT recipients.

Table 3 Proposed process to standardize return to school recommendations for patients undergoing hematopoietic cell transplant.

There are certain limitations of our study that need to be acknowledged. While we noted a modest response rate of 30%, potentially limiting the generalizability of our findings, the variations in return to school timing and support were quite evident from the responses. However, our findings could be biased if only those who believed that returning to school is challenging and were more likely to have responded to the survey. While our analysis included respondents from several institutions across the United States, given the relatively small sample size, we were unable to perform a multivariable analysis. The survey was limited to HCT physicians, and therefore we were unable to understand the perspectives of other healthcare professionals, such as advance practice providers, nurse coordinators, social workers, and psychologists, who play key roles in the post-HCT return to school process. Lastly, while this survey was conducted during the COVID-19 pandemic, respondents were asked to specifically provide answers without considering the school closures and COVID-19 transmission risk among HCT recipients. In fact, a separate survey was administered at the same time focusing on post-HCT return to school practices during the COVID-19 pandemic, and the findings have been previously published [11].

Notwithstanding, our analysis provides an important insight into the post-HCT return to school process from HCT physicians’ perspective. Using the data from this study and with help of all involved stakeholders, such as educators, social workers, and psychologists, we anticipate the development of standardized return to school recommendations. Additionally, the results of this study will help increase awareness of clinicians regarding school-related challenges for recipients of HCT, as well as increase their engagement in developing and testing future interventions to improve the return to school experience, and in turn quality of life, of HCT survivors.
