Barriers And Facilitators To SDM
Potential adopters
Our results revealed an overall positive attitude towards SDM among clinicians, with most expressing that following a patient’s preference is ideal and that SDM should be more prevalent in clinical practice than it is currently. They mentioned several factors that may hinder SDM in practice, namely time pressure/efficiency, the nature of SDM itself, patient characteristics, and clinician characteristics.
More than half (five out of nine) clinicians mentioned time pressure as the biggest barrier to SDM. Some perceived it to be an inefficient process to engage in dialogue with the patient about his preferences. Two clinicians noted that it is easier to decide the treatment option themselves based on their clinical experience. Time constraints were a more significant barrier for urologists, with radiation oncologists reporting that they have enough time for the patients. Three urologists mentioned that their consultations average 10–15 minutes. Radiation oncologists said that they have around 45–60 minutes to discuss treatment details, and one nurse reported having 30–45 minutes for each patient and more time if necessary.
’I think that [SDM] is much less efficient, it is very time-consuming. [...] It is far easier to just say “This is [the best option]”.’ (Radiation oncologist 2)
Five clinician expressed doubts about SDM as a paradigm, highlighting the burden that SDM may place on the patient by making him responsible for treatment choices. Patients can get overwhelmed by the volume of clinical information needed to make treatment decisions. They may also lack complete or balanced information, which makes it more difficult for them to make an informed choice. The need to make a treatment choice may also induce stress and confusion.
‘[SDM] asks a lot of the patient. And that also means where things go wrong, which happens sometimes, of course, you also have those people who have been irradiated and who [regret it]. They say “I should have chosen operation.” […] We now place the choice with the patient and with it the responsibility more or less is on him.’ (Urologist 3)
Finally, certain clinician characteristics were thought to influence the scope for SDM. Expertise was one characteristic; clinicians are more knowledgeable about their own specialization and may have less experience with other treatments. For instance, urologists are able to provide information on surgery in greater detail than on radiotherapy in which they have less direct expertise. However, they are the lead clinicians overseeing most of the treatment trajectory and are responsible for having the decisional talk with the patient. Four clinicians found this a significant barrier to SDM because incomplete information may prevent the patient from making a balanced choice. Another characteristic mentioned by one participant was the clinician’s age, with the perception being that younger clinicians are more open to SDM while it requires a mentality change for their more senior peers.
‘The age-old discussion is that people preach to the converted. [...] I would say the patient has to have surgery, a radiation oncologist would say he has to have radiotherapy.’ (Urologist 1)
The biggest facilitator at the individual level was the motivation of the clinician leading the treatment process (in this case, the urologist). Clinicians reported that they would be more open to SDM if they were convinced that it leads to better patient outcomes and does not lengthen the decision-making process.
‘[They] must also see the benefit, that patients are more satisfied, that they get more insight into their disease, that they ultimately have a better quality of life. The person implementing or actually offering it to patients must be convinced of that.’ (Radiation oncologist 1)
Practice environment
Participants cited two main barriers in the clinic environment: patient characteristics and structural factors. Patient characteristics included the patient’s age, health literacy and willingness to participate in SDM. Three clinicians mentioned that the advanced age of the typical prostate cancer patient makes it challenging to engage the patient in the decision-making process. Furthermore, many older patients are used to a paternalistic model of decision-making in which the clinician advises the patient on the best treatment. The wide variety in patient backgrounds, some being more educated than others and better able to understand clinical information, presented another challenge according to one clinician. Finally, some patients are willing to take an active role while others prefer the clinician to take the lead, and even when decisions are made jointly, a considerable portion of patients are highly influenced by the clinician’s opinion.
‘You have to imagine that there are different [types] of patients. From highly educated to minimally educated and that involves a totally different manner of communication.’ (Urologist 1)
‘The patients, particularly the elderly patients [...], are more used to a paternalistic model, they believe [...] that the doctor knows what is best for them.’ (Radiation oncologist 2)
Four clinicians cited structural factors that may impede SDM. First, in the current treatment trajectory the urologist is the first point of contact for the patient and oversees most of the process, from initial diagnosis to the final decision. The urologist carries out the decisional talk with the patient and presents all relevant treatment options. If radiotherapy is chosen then the patient is referred to the radiation oncologist for further treatment, however many patients tend to choose surgery. Second, government-set quotas on the required number of surgeries to be performed by hospitals may incentivize treatment choices to be steered in that direction.
‘There are guidelines in the Netherlands on prostatectomy. To be able to do such a prostate surgery you must achieve a minimum number per year.’ (Radiation oncologist 3)
‘We also have to get a certain number of operations and that is also from the government.’ (Urologist 4)
Clinicians suggested several actions that would facilitate SDM implementation, beginning with making it an organizational priority. Creating the time and space for it, both literally in terms of more contact time with the patient and physical set-ups such as joint consultations, and logistically such as through training and addressing external factors such as treatment quotas. Clinicians suggested training to acquaint their peers with the principles of SDM and how to elicit participation from the patient. Some clinicians valued an e-Learning course about the basics of practicing SDM, others suggested face-to-face demonstrations so that clinicians could inform and educate their patients more effectively.
Joint consultations were proposed to reduce information asymmetry between the different specializations. If radiotherapists and urologists were to participate in consultations together with the patient this could improve the decision-making process by giving all parties a more balanced perspective of the options available and patient’s preferences. Despite the potential benefits, most clinicians highlighted the organizational challenges this level of care coordination may present.
‘An online [course] is the easiest as you can follow it in your own time […] the so-called e-Learning.’ (Radiation oncologist 3)
’It would be great to have an oncology center for example, where you could discuss everything with another specialist [...] but that is also difficult.’ (Urologist 4)
‘The [hospital] must be ready [for] the extra logistical challenges […] to have two doctors in place of one, and preferably at the same time or at the same clinic.’ (Radiation oncologist 3)
Barriers And Facilitators To PDAs
In light of existing time pressures, clinicians said they would be less likely to use the PDA if it was too complicated to understand or apply. This included factors such as the time taken to navigate through the PDA, fill in information such as patient details, and discuss the outputs in the consultation with the patient. Another potential barrier was accessibility in the case of a web-based PDA; patients, particularly the elderly, may not be familiar enough with PCs/tablets to use the PDA.
‘If we have to log in […] it will cost us a lot of time and energy. It should therefore remain simple.’ (Urologist 4)
‘If the decision aid is too difficult or too complicated then it is not usable. So you have to adjust it to the mainstream population of course." (Radiation oncologist 1)
‘So people have to have access to a computer, access to the internet. If there are people who really don't understand or who can't read or who can't use a computer or don't have internet access, yes then it is difficult.’ (Urologist 2)
Numerous facilitators were proposed, both on the PDA-level as well as in the development process. Three radiation oncologists and two urologists cited the critical role of the urologist in implementing a PDA as urologists are the first point of contact for the patient after referral and oversee a large part of the treatment trajectory. Motivating the urologist was seen as a stimulating factor, as the clinician who offers the PDA must be convinced of its added value. This can be enhanced by showing positive results associated with the use of PDAs, for example that patients may face less decisional regret and accept the side effects and complications more readily if he has opted for treatment himself.
At a structural level, embedding the PDA in the patient pathway in a standardized manner was seen as an ideal way to make the informing process more efficient. Oncology nurses were named as the most effective channel through which the patients could be introduced to the PDA and guided through the process of applying it, since they were regarded as more approachable for the patients. Involving additional personnel in this manner was thought to save time during consultations. The present role of oncology nurses is to provide the patient with practical and logistical information about their treatment options. These include the procedures for the different treatments and the implications in terms of hospital visits and so forth. We did not find evidence that nurses engage the patient in actual deliberation or decision-making; this function appears to be performed solely by the clinicians. Finally, two clinicians mentioned compensation for the use of PDA as a facilitating factor.
‘All the diagnostics and the workup up to and including the diagnosis, plus discussing the tumor board decision are all with the urologist himself. So he is the key player; if he does not use it or does not recommend it, nothing happens.’ (Radiation oncologist 3)
‘[Implementation] is only possible if all clinicians are obliged to use [the PDA]. But that will never happen of course. Unless instead, you get compensation from the health insurance company.’ (Radiation oncologist 1)
