Should I or shouldn’t I: perspectives regarding the decision-making process on stem cell treatments

Deciphering available information, from both online and other sources, can be difficult for individuals trying to decide whether or not to travel and pay for possible stem cell treatments. Often these individuals seek out advice and guidance from others they perceive to be more knowledgeable on stem cell treatments to help them make their decisions. Interviews conducted by Dr. Claire Tanner and colleagues reveal many of the challenges and frustrations patients, carers and professionals - acting as advisors – experience. They also highlight the need to create better resources and call for one-on-one discussions to better support those contemplating alleged stem cell therapies that are yet to be shown to be safe and effective.  

What background and points are discussed?

Dr Tanner and her colleagues interviewed 24 patients or carers that had participated in unproven SC therapies and 27 individuals who contemplated treatments but did not get them. Twenty professionals were also interviewed, including SC researchers, clinicians and representatives from patient advocacy groups (for example, MND Australia and Cerebral Palsy Alliance). Interviews with patients and carers illustrate that individuals often explore a wide range of information on SC therapies, discuss SC treatments with their clinicians and seek out at least one 'professional' they perceive to be knowledgeable in science or medicine. These 'professionals' range from scientific researchers and medical practitioners to acupuncturists and science students. Dr Tanner and colleagues refer to these professionals as ‘accidental advisors’, because they are approached for advice due to their line of work but may not have a sufficient understanding of SC therapies or training to counsel individuals and families.

The interviews with patients, carers and professionals reveal several recurring issues and frustrations. Accessibility is a concern raised by some individuals who were greatly frustrated because repeated attempts to contact professionals were never answered. On the other hand, several professionals commented that their work doesn’t allow the appropriate amount of time to counsel patients and families. The authors note that in some cases information provided by accidental advisors about the risks, effectiveness and safety of SC treatments was inconsistent with information and resources produced by experts. Surprisingly, interviewed advocacy group representatives were more likely to refer to patient handbooks and professional guidelines than researchers or clinicians. Accidental advisors offered a range of opinions, some supported traveling for SC treatments, several claimed it won’t cause any harm, some advised against treatments and other advisors took a neutral position. Individuals expressed frustration when advisors said not to get treatments without any further explanation. People also found it frustrating when advisors were indirect, reluctant to offer advice or encouraged individuals to do more research and make their own decision. Patients and carers perceived this later approach as advisers lacking knowledge on SCs, being disingenuous or attempting to avoid taking any responsibility. The authors note that some advisors did refer people to others if they felt they didn’t have appropriate scientific background or counselling expertise. However, other advisors deliberately avoided giving advice, saying that this is the role of a patient’s clinician or that there are legal and liability issues about advising on SC treatments.
