Twenty-two interviews were conducted between June and September 2019. Interviews lasted between 20 and 60 minutes (mean 35 minutes), 16 were by telephone and six face-to-face.
Participants were aged between 33 and 73 years (mean age 47 years), with 13 male and nine female, 16 practised in the state of Queensland (with 2, 3, and 1 located in New South Wales, Victoria, and South Australia, respectively), and the number of years since graduation ranged from 5 to 34 years. Practice postcodes indicated all GPs worked in either urban (n = 11) or inner-regional (n = 11) settings. A review of GP practice websites indicated six GPs had a specific interest in mental health.
Three main themes provide the overarching structure under which GPs’ insights are discussed within each subtheme. Box 2 lists these with a summary statement reflecting the focus of each subtheme.
Theme 1. Discontinuation of long-term use of antidepressants is not a simple deprescribing decision
GPs emphasised discontinuing long-term antidepressant use was broader than a medical deprescribing decision. This theme describes the thorough exploration of the patient’s context, the complexities involved in shared decision-making, and extensive consideration required to assess preparedness for discontinuation.
Theme 1: Discontinuation of long-term use of antidepressants is not a simple deprescribing decision |
Subtheme | Focus |
Assessing patient preparedness | Patients’ life circumstances are as important as recovery from depression in assessing patient preparedness for discontinuation. GPs acknowledged patient relationships with antidepressants that can disrupt preparedness to discontinue. |
Subjective and relational decision-making | GPs described decision-making about discontinuation in intuitive and relational terms. |
Weighing up benefits and risks | GPs recognised patient empowerment and sense of recovery as potent motivators for ceasing long-term use. |
Theme 2: Discontinuation of long-term use of antidepressants is a journey taken together by patient and GP |
Subtheme | Focus |
Planting the seed for change | GPs valued a process of careful preparation for discontinuation. |
Co-designing a personalised plan | A tailored plan of action enables GPs and patients to increase the likelihood of successful discontinuation: a gradual dose reduction plan and proactive relapse plan are considered crucial. |
Care continues during and after discontinuation | GPs emphasised regular review and encouragement of social and lifestyle supports during and beyond discontinuation. |
Theme 3: Supporting change in GPs’ prescribing practices |
Subtheme | Focus |
Redressing repeat prescribing as the quick fix | GPs expressed distrust in prescribing norms and felt a need to shift away from ‘set and forget’ attitudes. |
Inadequate evidence to support discontinuation | Discussions with patients about discontinuation would be facilitated by better evidence about the harms of long-term use. |
Practice-based change | GPs expressed well-communicated ideas about practice level change that would help them discontinue antidepressants. |
Solutions beyond general practice | Discontinuation of long-term antidepressant use at the level of the GP–patient alliance will be leveraged by action at the broader system level (for example, social and policy). |
Box 2. Themes and subthemes
Assessing patient preparedness
Personal and social circumstances were viewed as equally important as recovery from depression in assessing patient readiness. Having a stable relationship, employment, presence of social supports, low financial stress, awareness of triggers, engagement in self-care, and healthy lifestyle were repeatedly advocated as critical:
‘And so it’s normally at a stage when they’re quite stable mentally and they feel pretty good in themselves, they haven’t really needed any other psychological interventions, and that’s usually when I find they’re more responsive to coming off therapy when there’s no other crises going on in their life.’
(GP04, M[Male], 38 years [age])
Patient reluctance was a potent barrier to GPs broaching the topic of discontinuation. They used language to describe this reluctance such as ‘pretty adamant’ (GP20, F[female], 58), ‘once they’ve made up their mind’ (GP14, F, 33), and ‘ hesitant’ (GP05, M, 41 years).
GPs acknowledged patient relationships with antidepressants may undermine their preparedness and noted patients need to want to stop. In particular, several GPs felt the relationship some patients have with their antidepressant is part of their identity and this may be a barrier:
‘I think the single biggest factor is really the patient factor. If the patient really finds that they like the sedation, they’ve got a sense of “I can’t change … This is who I am …”’
(GP10, F, 54 years)
Failed previous attempts can moderate patients’ future readiness, raising the level of concern among GPs about enabling unsuccessful attempts:
‘Because if you stop them at the wrong time you lose the opportunity to stop them again in the future, sometimes.’
(GP12, M, 36 years)
There were circumstances where GPs would not attempt discontinuation even if indicated. They mentioned the importance of respecting patients’ preference to remain on their medication. A few GPs indicated that for older patients who have been on antidepressants for a long-time (in some cases decades) ‘getting depressed again at seventy-five usually is not worth the risk.’ (GP09, M, 54 years) . Others suggested dose reduction rather than discontinuation was an adequate outcome in some circumstances, particularly when the patient is reluctant to cease, is in an unsafe or unstable environment, has inadequate social supports, or has experienced significant trauma:
‘If a patient wasn’t willing. I mean, I’d have the conversation with them and I’d try to explain it. But, for example, this elderly lady that I’m thinking of … she just didn’t feel like she could manage without it. And I felt that what I understood of her childhood trauma and the fact that I was meeting her in her seventies, I had to just trust her judgement on that. And that maybe she did have quite profound ongoing impacts of that trauma that meant she needed to continue the medication or at least felt that she did. So I just had to respect her decision on it.’
(GP07, F, 46 years)
Subjective and relational decision-making
GPs described their decision-making in intuitive and relational terms. They mentioned trust, being aware of the person’s situation and highlighted the subjective nature of the decision-making:
‘ So, you feel like you really are doing this alone and there’s not really clear guidelines about when you should stop medication; it’s all a little bit subjective … So it is sort of based on intuition and a good relationship with the patient, so that is sometimes not as clear-cut as following a guideline and that might also be what stops us discontinuing it. It’s quite a subjective area.’
(GP14, F, 33 years)
GPs repeatedly likened the process of antidepressant discontinuation to smoking cessation or dependence management, with one GP describing them as ‘modern day mother’s little helper’ and a ‘crutch’ (GP10, F, 54 years), while another said:
‘But to me it’s a little bit like quitting smoking, they’ve got to be ready to want to stop, even if you tell them about the side effects and that they don’t need to be on it as many times as you want but if they’re not ready then in my experience it won’t go very well.’
(GP14, F, 33 years)
The strength of the GP–patient alliance influences decision-making about whether to raise discontinuation, or challenge a patient’s reluctance to try or indeed try again. A weak therapeutic alliance is a barrier:
‘Are they my regular patient … are they likely to come back to me? I don’t think that ... if there was you know the inability to follow-up easily that I would do it.’
(GP22, F, 52 years)
Weighing up the benefits and risks
GPs agreed there are many benefits and few risks to ceasing long-term use when no longer indicated. The reversal or removal of side effects, the removal of emotional numbing, reduced medication burden, reduced polypharmacy risks, and removing the burden of cost are all motivators for discontinuation. Many GPs’ emphasised the empowering effect of being released from medication reliance. They felt discontinuing could increase a patient’s wellbeing by virtue of them being able to manage symptoms and recognising they were in control rather than feeling the medication was controlling the symptoms:
‘The patient gains new life, they feel like, “I don’t need it! I’ve regained my life. I don’t need to be dependent on anything.”’
(GP16, M, 62 years)
Few GPs expressed concern about the risk of suicide, the risk of relapse was the most common concern:
‘The risks are that you can make a stable situation unstable and so that is a risk that you have to weigh up.’
(GP22, F, 52 years)
Theme 2. Discontinuation of long-term use of antidepressants is a journey taken together by the patient and the GP
GPs emphasised there is no standardised approach, it is about finding the appropriate strategy for each patient. Discontinuation was described as a journey taken together with ongoing discussions over time to review progress and better prepare patients to optimise outcomes. Making clear to patients they are not doing this alone is key and requires being fluid and responsive to the patient and their circumstances.
Planting the seed for change
Joint reflection with patients about why antidepressants were initiated and using the right language, can increase the likelihood of successful discontinuation. GPs used tentative language such as ‘broach the subject’ (GP14, F, 33 years), or said they ‘keep bringing it up.’ (GP19, M, 33 years) with the patient from time to time. They considered themselves to be planting the seed:
‘So, I would say “can we consider getting you off this?” And either acting on the thought there if they’re agreeable or planting the seed that maybe next time we could do that or in a few months ’ time when their life’s treating them a bit better to give it a go.’
(GP11, M, 38 years)
GPs argued for setting-up a period of preparation where enablers of success could be put in place:
‘We plan the timing of the first step down, we make sure it’s a good time in their life ... not at a stressful time.’
(GP20, F, 58 years)
Some GPs use standardised tools for identifying symptom change as part of the discussion with patients about discontinuation:
‘I don’t want to spend too much time on tools … I find it’s a useful measurement to discuss with the patients about how effective the antidepression treatment is. So, if I can say — look your K10 when we started you on the antidepressants you were 35 and now you’re down to 22 … I think it’s having a good effect.’
(GP10, F, 54 years)
Co-designing a personalised plan
Gradual tapering was mentioned almost universally as critical for discontinuation. Many GPs recognised that tapering plans need to be personalised as weaning periods are hard to establish due to variation in antidepressant type and dose, the message was clear — they go as slow as needed and generally slower than withdrawal regimens suggest:
‘I just go slow as I think the patient [needs] … and look we might get to a dose that’s not therapeutic but it’s sort of a more just easing them back in to nothing and just showing them that they can do this without the medication.’
(GP14, F, 33 years)
Being proactive about relapse planning is central to the process. Talking to patients about how they will recognise if they are not doing well, possible warning signs, and what they might do if they notice these signs, such as calling on social supports, returning to the GP, or re-engaging with mental health support were all mentioned as important:
‘And I really like them to have, at least, talked about their other strategies they might use to manage things given that life does throw people curve balls. … Trying to, out loud, describe what they might do to both prevent and also monitor things … What are their early warning signs? … What might they do if they notice that? When would they come back to see me, when would they go and see their counsellor? Would they call on their support people? Just having a bit of a plan around that.’
(GP20, F, 58 years)
GPs felt inadequate discontinuation planning meant patients may mistake withdrawal for relapse so preparing patients by helping them distinguish between withdrawal and relapse is key, as is preparing patients for the possibility that ceasing long-term use may be uncomfortable:
‘I warn patients as much as possible about the fact that they will get some withdrawal … I’ll also suggest to them that it will be uncomfortable but it’s likely to be short-term ... I try to distinguish between the immediate sort of 2-week [withdrawal] effect rather than the 2-month [relapse] effect, and tell them what might feel different about those scenarios, and ... that one is quite highly expected and the other ... hopefully won’t happen.’
(GP10, F, 54 years)
Care continues during and after discontinuation
Regular review during discontinuation enables symptom monitoring and reinforcing the importance of adhering to lifestyle measures, such as exercise, diet, sleep hygiene, social supports, and possibly psychological support. The value of frequent and regular review was stressed:
‘But if they’ve been on it for a long period of time then I’ll want to see them every two weeks or even every week depending on how comfortable they feel. Because if they’re not supported at the cessation stage then they will most likely say I will need to be on this for the rest of my life.’
(GP19, M, 33 years)
GPs had mixed opinions about whether a patient who was feeling ‘well’ would want to engage with psychological support. Some felt re-engaging with psychological support and social groups may make discontinuation more successful:
‘I won’t say a better time but it might be at a time that if they’re better they’re actually more likely to go along [to non-pharmacological support]. Whereas, at the beginning stage it’s very hard … when people don’t have motivation to get out of bed ... So, maybe when they’re recovered it’s better.’
(GP11, M, 38 years)
Theme 3. Supporting change in GPs’ prescribing practices
This theme conveys GPs’ ideas about the individual, practice, and societal changes needed to support them to discontinue long-term antidepressants.
Redressing repeat prescribing as the quick fix
Providing a script for antidepressants was seen as an easy GP action that might allay symptoms as well as comfort patients. For example, one GP noted it was often easy to ‘ let sleeping dogs lie’ and ‘ don’t fix it if it ain’t broke.’ (GP02, M, 56 years).
Prescribing and repeat prescribing were viewed in some cases as easier than attempting to address patients’ often complicated economic, social, and personal issues through lifestyle change and talking therapies:
‘So, I suppose it is easier to prescribe a medication than it is to counsel, look at non-pharmacological things. It may feel like you’re doing more by giving a medication than just saying “oh, we’ll try these other things.”’
(GP02, M, 56 years)
Some GPs saw antidepressants used in a way that ‘ disempowered ’ (GP10, F, 54 years) and caused ‘ learned helplessness’ (GP10, F, 54 years), and wanted to redress the approach to them as a panacea for all distress.
In particular, some GPs felt it was imperative to be clear about the limited duration of antidepressant use on their commencement, thereby avoiding any preestablished beliefs patients may have about antidepressants being for life, and priming them for the discontinuation conversation in future:
‘So, when I do start someone on antidepressants I say “Well I don’t believe this should be something you take forever ... I intend to review it every 3 months and then to come off after you’ve been stable for at least 6 months.”’
(GP17, M, 36 years)
While patients’ attitudes and reluctance to discontinue can reinforce and encourage the use of antidepressants as a quick fix , GPs also commented on the need to redress their own ‘ set and forget’ (GP22, F, 52 years) attitude:
‘There is a little bit of an underlying rule that once you start this medication nobody thinks to stop it.’
(GP14, F, 33 years)
Inadequate evidence to support discontinuation
GPs distinguished between evidence about side effects and evidence about adverse health outcomes of long-term use. The former has a strong evidence-base well-articulated by GPs. Yet, there was an awareness that despite the widespread use of antidepressants, GPs mentioned they were not aware of research investigating potentially adverse health outcomes of long-term use.
GPs felt it was difficult to have the conversation with patients or justify to them why they should discontinue their use of antidepressants without being able to communicate the harms of long-term use:
‘I think that long-term evidence is actually quite limited about any harms of long-term use. It is very difficult because most of the trials with antidepressants are short-term.’
(GP09, M, 54 years)
Practice-based change
Most GPs felt they had sufficient knowledge and experience to provide adequate advice to patients around discontinuation. Yet, increased education for GPs in a variety of mediums, patient handouts, and better support for GPs were all mentioned as potentially helpful. Opportunities for auditing and benchmarking was a common recommendation:
‘I think … clinical audits are good things … maybe not an in depth clinical audit but just something as part of a continuous professional development program.’
(GP02, M, 56 years)
They spoke about removing well-known service delivery obstacles that interfere with their ability to deliver comprehensive and independent mental health care in general practice:
‘I worry that it has something to do with the push to do 6 minute medicine and that this is the easier option sometimes than spending time with the patient and talking with the patient ... I hope we’re educating our GPs better than that and we’re empowering them to do more without medication.’
(GP22, F, 52 years)
GPs pointed out there is conflicting advice about the rate at which antidepressants should be reduced. Some preferred to be guided by their own clinical experience and protocols. Current guidelines provide little clear advice for managing patients who are long-term users:
‘So, in terms of guidelines, I’m not aware of any if there’s any.’
(GP16, M, 62 years)
Several GPs mentioned the ongoing influence of the pharmaceutical industry in general practice and its potential contribution to medication overuse, including long-term use of antidepressants:
‘And, just finally, I think that the biological model of management of depression and anxiety has been so strong for so long that drug companies are really at the centre and core of all of this and that unfortunately the majority of doctors are getting their education from drug companies directly or indirectly.’
(GP10, F, 54 years)
Solutions beyond general practice
Having better access to affordable psychologists, including in-house psychologists and other non-pharmacological supports at the point of discontinuation were seen as enhancers of success:
‘… we’ve got access to psychologists but it’s not ready access ...’
(GP08, F, age unknown)
Although being interviewed about a clinical deprescribing process, GPs were repeatedly drawn to make non-medical observations about the use of antidepressants and many sought solutions within the broader social and policy environment.
Some believed there was a need to shift the conversation to one that considered how mental health and antidepressants were viewed in the community, and how current attitudes and beliefs could contribute to a culture of overprescribing and low rates of discontinuation:
‘It’s probably nothing to do with doctors, it’s actually changing the conversation in our society about what causes anxiety and why … the management of anxiety baseline is not a medication, it’s not a drug, but it’s about finding ways to manage it by changing your lifestyle.’
(GP10, F, 54 years)
