A qualitative exploration of the informed consent process in hematopoietic cell transplantation clinical research and opportunities for improvement

Consenting rather than choosing. A qualitative study on overseas patients' decision to undergo hematopoietic stem cell transplantation

OBJECTIVE

Reasons for patients' acceptance of the allogeneic hematopoietic stem cell transplantation (allo-HSCT) proposed and how their decision may be affected by the long distances involved have not been sufficiently investigated so far. We therefore conducted a qualitative study to identify the factors involved in overseas patients' decision to accept allo-HSCT.

METHODS

In-depth semi-directive interviews were conducted with overseas allo-grafted patients (n = 22), as well as one non-consenting patient and their caregivers (n = 24). Interviews were analyzed taking an inductive thematic approach.

RESULTS

Respondents stated that their decision to undergo the transplantation was constrained by their feeling of being in a therapeutic impasse, the need for a survival strategy, the need to survive for their family's sake, family and doctors' pressures, and the feeling of being managed. The following factors favoring patients' acceptance were the medical information received, their faith, having a family donor, peer testimonies, and positive representations of the transplantation. Factors against patients' acceptance were geographical distance from home to the transplant center, apprehension of protective isolation, fear of dying, and representations of the graft.

CONCLUSIONS

These factors, such as patient's personal values and representations, need to be weighed up in order to adapt the information exchanged accordingly. Efforts are required to relieve patients' social isolation and improve the means of providing family support.

Motivations and Decision-Making of Adult Sickle Cell Patients in High-Risk Clinical Research

Potentially curative but high-risk trials of gene therapy or stem cell transplantation (PBSCT) for sickle cell disease (SCD) pose new opportunities for adults with SCD, many of whom experience significant disease burden and complications with few treatment options, as well as stigma and disparities in care. We explored motivations and decision-making processes of enrollees and decliners of such trials. Semistructured interviews were conducted with a purposive sample of 20 enrollees and 6 decliners. Interviews explored participants' SCD experiences, motivations, and decision-making about trial participation, understanding of research-related information, and retrospective reflections. Interviews were analyzed with content analysis. Most identified the purpose of research, risks, and uncertainties of participation. Both enrollees and decliners described deliberative weighing of study risks and potential benefits (especially the prospect of a cure), with heavy factoring of their SCD status, experiences, and desire for a better life. Despite the influence of spirituality/religion and support of family and friends, all described the decision about participation as their own. In some patients, the primary outcome status defined by the trial did not match the patients' perceived outcomes. Patients with negative experiences expressed a desire for greater emphasis on risks and possible outcomes during informed consent. This cohort of adults with SCD were thoughtfully deliberative in their decisions about gene therapy or PBSCT trials. Future participants' decision-making may be enhanced by emphasizing that "successful" scientific outcomes can still involve complications or symptoms and be facilitated by referrals to former research participants and anticipatory discussions.

No Evidence for Particular Association Between HLA-Haploidentical Hematopoietic Stem Cell Transplantation and Psychological Distress

BACKGROUND

The psychological distress experienced by patients scheduled for hematopoietic stem cell transplantation (HSCT) is of clinical concern. However, distress experienced by patients scheduled for HLA-haploidentical HSCT vs that of patients scheduled for other types of matched HSCT is unknown. We conducted a retrospective study to clarify whether the type of HSCT influences the appearance of psychological distress in patients anticipating HSCT.

METHODS

One hundred fifty-seven patients who had undergone any of 4 types of HSCT at Tokyo Metropolitan Komagome Hospital between October 2013 and September 2016 and had completed the Profile of Mood States (POMS) questionnaire within 2 weeks before the procedure were included. We computed T-scores for the tension-anxiety (TA) and depression (D) subscales, took scores ≥ 60 to represent mood disturbance of clinical concern, and examined scores and other clinical variables in relation to each procedure.

RESULTS

Twenty-two (14.0%) patients had a POMS-TA score ≥ 60, and 26 (16.6%) had a POMS-D score ≥ 60. The numbers of POMS-TA and POMS-D scores  ≥ 60 did not differ significantly with respect to age, sex, leukemia type, number of previous transplants, disease status, comorbidity index, or transplant type. A multivariate logistic regression analysis confirmed the absence of an influence of the type of HSCT on the incidence of POMS-TA or POMS-D scores ≥60.

CONCLUSION

Attention should be paid to the matter of psychological distress in patients with leukemia who will be treated by HSCT, even HLA-haploidentical HSCT. Such patients need psychological support, especially during the waiting period immediately prior to the transplantation procedure.

Improving the Informed Consent Process in Hematopoietic Cell Transplantation: Patient, Caregiver, and Provider Perspectives

One of the significant modifications to the Common Rule is the requirement that prospective participants be given information sufficient for a "reasonable person." However, research is limited on what types of information patients, caregivers, and providers consider "key information." Although certain aspects of informed consent (IC) may be considered standard, considering the individualized needs and preferences of patients is necessary for patient-centered consent. In this study, we qualitatively examined the specific types of information that patients and caregivers involved in hematopoietic cell transplantation (HCT), as well as their providers, believe to be important and necessary as part of the IC process to make a decision about participating in clinical research; and further, how these perspectives are aligned. Our findings suggest opportunities for improving the IC document and process by emphasizing information of importance to patients, such as the benefits to others and contributions to science that are associated with participation in clinical research. Furthermore, increasing patient engagement during the IC process may allow providers to streamline information that is aligned with patient information needs and preferences.
