Summary
A Pan-European group of psychiatric trainees conducted a semi-structured web-based sur-
vey of factors influencing decision-making in relation to antipsychotic, antidepressant and
mood stabilizer prescribing. The acceptance of such a survey is in itself a positive result. In
the current climate of evidence based medicine and guidelines, preliminary results from this
survey suggest that, when asked regarding treatment choice for themselves, psychiatry trai-
nees preferred second-generation atypical antipsychotic medication, based on perceived ef-
ficacy. The results for mood stabilisers were less striking. The relevance of this survey, in the
context of recent evidence, may relate to trainees’ perceptions as opposed to evidence base.
Zusammenfassung
Eine paneuropäische Gruppe von Ärzten in psychiatrischer Facharztausbildung hat eine
halb-strukturierte, Internet-basierte Umfrage zur Verschreibungspraxis antipsychotischer,
antidepressiver und stimmungsstabilisierender Medikamente sowie der entsprechenden Ent-
scheidungsfindung durchgeführt. Die Akzeptanz, auf die die Umfrage selbst stieß, stellt an
sich schon ein erfreuliches Ergebnis dar. Im gegenwärtigen Klima evidenzbasierter Medizin
und Richtlinien weisen die vorläufigen Umfrageergebnisse darauf hin, daß – wenn es um die
Frage geht, welche Präparate im Falle einer Eigenbehandlung ausgewählt würden atypische
Antipsychotika der zweiten Generation bevorzugt werden, wobei sich die Entscheidung der
befragten Mediziner an der (subjektiv) wahrgenommen Wirksamkeit orientiert. Die Ergebnis-
se hinsichtlich stimmungsstabilisierender Medikamente waren weniger auffällig. Die Bedeu-
tung der Umfrage könnte, im Kontext jüngster Forschungsergebnisse, auf den Faktor Wahr-
nehmung gegenüber evidenzbasierter Forschung hinweisen.

Treatment choices in psychiatry, from the days of insu-
lin coma therapy to electroconvulsive therapy, have al-
ways courted controversy, and this continues to the present
day. Stalwarts of “modern” psychiatric practice, such as
“second generation atypical” antipsychotic drugs have
been exposed to non industry-sponsored trials (1–3), a re-
cent meta-analysis questioning their very concept and per-
ceived benefits over older (more cost-effective) counter-
parts (4). It is worth noting that, though numerous studies
have looked at factors affecting treatment adherence in
major psychiatric illnesses, relatively few have looked at
factors influencing professionals’ decision making (5).
Methods used include semi-structured interviews with psy-
chiatrists (5), and, more recently, preference for psychia-
trists’ own treatment (6–8). Results from these studies have
shown that clinicians may challenge evidence-base and
guidelines, based on a number of factors, including clinical
experience. The majority of this work has been at a local
level (in one case a national survey), and all but one survey
pertained only to the prescription of antipsychotic medi-
cation. A vast proportion of responses were from Consul-
tants/Specialists. The responders based their choices on

perceived efficacy (7, 8), in addition to side effect profile
and cost. Though a National survey exists with regard to
treatment choices, to date there has been little work exam-
ining trainee psychiatrists’ views on treatment. Moreover,
populations that have been looked at have only included
those from the United Kingdom and Germany (6–8). In this
context our Pan-European Research Group, composed ex-
clusively of trainees, sought to ascertain treatment choices of
trainees from various countries, the factors influencing these,
and whether treatment choices were uniform when trainees
were asked which treatment they would choose to receive.
The European Federation of Psychiatric Trainees (EFPT)
is a trainee organisation, encompassing official represen-
tatives from 24 different countries. At the Annual meeting
of the General Assembly (held in Gothenburg in 2008) a re-
search group was incepted, with the express aim of facili-
tating trainee-led collaborative research, focusing on work
that had implications for psychiatric trainees across Europe.
The group produced a mission statement, and was original-
ly composed of 9 members. A web-based research environ-
ment was created, and the composition of the group in-
creased to 19, with representation from 16 different Euro-
pean countries. Following discussion from amongst the
group it was decided to focus initially on trainee surveys,
facilitated by online resources. The EFPT forum represents a
unique opportunity for trainees to discuss training and
wider issues with “like-minded” colleagues from differing
countries and cultures, and following a number of dis-
cussions pertaining to differing clinical practices, it was
agreed to focus on treatment choices and guideline imple-
mentation amongst European trainees.
Methods
Within the research group various methodologies were dis-
cussed, a semi-structured survey being considered optimal,
utilising findings from prior work (6,7,8), The survey was
piloted with delegates attending the Forum in Gothenburg,
resulting in an agreed revised format. We invited all 24
countries to participate. To ensure adequate reliability, a
sample size of 50 was agreed upon from each country, from
a sample deemed by the representative to be homogenous.
A response rate of 50% was set as a minimum for results to
be collated. The survey was distributed in English, via a
web-link, and in some cases representatives chose to dis-
tribute the survey using paper copies, data being entered
into the online survey tool manually.
The survey consisted of questions on:
a) demographics (country, number of years in training,
gender, specialty).
b) guidelines; whether National or International guide-
lines existed, and whether they were implemented (if
not, reasons for this)
c) preferred choice of antipsychotic/mood stabiliser/
antidepressant to treat patients in given scenarios, and
factors influencing choice (rating preferences between
cost, efficacy, side effect profile and other factors). For
antipsychotics, participants were asked if recent trials

Preliminary Results
At the time of submission, the study was still underway, and
therefore results given are preliminary, and are liable to
change as the study progresses. The main areas presented in
this article relates to treatment choices trainees would
chose to receive themselves. Country responses are given in
Table 1; only responses from those countries that met inclu-
sion criteria (50 responses with at least 50% response rate)
are included. Countries included in this preliminary analy-
sis are France, Portugal, Romania and Scotland (n=219).
Preliminary analyses are presented below.
Treatment choice of antipsychotic
95% (n=208) of trainees would choose to receive an “atypi-
cal” antipsychotic (excluding Clozapine), 5% (n=10) choos-
ing a “typical” antipsychotic, one trainee choosing Cloza-
pine as first-line therapy. This is summarized in figure 1.
It should be noted that 28% (n=61) of those trainees
choosing to receive antipsychotic medication for a psy-
chotic episode stated their decision was influenced by the
CATIE trial.
Treatment choice of mood stabiliser
39% (n=85) of trainees would choose to receive Lithium,
20% (n=44) chose Sodium Valproate (n=44), 25 % (n=55)
chose Semisodium Valproate (Depakote), 3% (n=7) chose
Lithium and Valproate, 3% (n=7) chose Carbamezapine, 5%
(n=11) choosing Lamotrigine. Other responses included
variable combinations of the above treatments. These re-
sults are summarized in figure 2.
Factors influencing the choice of one’s own treatment
Factors influencing choice mapped onto three main do-
mains: efficacy, side-effect profile and cost (less than 5%
gave other reasons).
For antidepressants, 83% (n=182) felt efficacy most im-
portant, 50% (n=110) felt side effect profile most important
and 5% (n=11) felt cost to be the most important variable
(note that responders could rate more than one factor as
most important).
For antipsychotics, 81% (n=177) felt efficacy most im-
portant, 48% (n=105) felt side-effect profile most important
and 3% (n=7) considered cost of paramount importance.
For mood stabilizers, 81% (n=177) judged efficacy as the
most important factor, 47% (n=103) viewed side-effect pro-
file as most important and 5% (n=11) viewed cost as the most
important factor. These results are summarized in figure 3.
Discussion
It is heartening to note that trainees can collaborate on an In-
ternational basis, and that work can be carried out using dif-
fering information technologies, including online surveys and
web-forums. Though we are still progressing through data col-
lection, the inclusion criteria would seem justified, and should
be attainable in other countries. The results presented suggest
that trainees would prefer to receive 2nd generation “atypical”
antipsychotic medication, and that their decision-making is
based on presumptions of improved efficacy and side-effect
profile of these compounds, in keeping with previous work (7,
8). This is despite a proportion of trainees stating that they
were influenced by trials, such as CATIE, and in the context of
recent evidence suggesting there is no significant difference in
tolerability of side effects or efficacy (4, 9). The finding that
most trainees would choose Lithium as a mood stabiliser,
based on efficacy is not surprising, given the predominance of
literature suggesting this (10), though the high number who
based their decision-making on side-effect profile is interest-
ing, given the relative tolerability of other mood stabilisers. In
both treatment choices cost did not figure significantly.
It would be interesting to correlate these findings with pres-
ence and implementation of guidelines. The relevance of
guidelines with specific reference to cost-effectiveness needs
to be acknowledged. Recent literature may lead to paradigm
shifts in our decision-making (4, 11). Further analysis of this
data may shed some light on the interplay of factors influenc-
ing decision-making of trainees, with reference to the treat-
ment options they would elect to receive.
We would like to thank Dr. Amit Malik (President, EFPT) and Martina
Rojnic (President-Elect, EFPT) for their support and guidance.
We appreciate the support of trainees who completed the survey.

Aims: The European Federation of Psychiatric Trainees (EFPT), founded in London in 1992, is an independent international federation of psychiatric trainees' national associations. The EFPT is engaged in several actions in order to pursue its general aims to promote high standards of quality of psychiatric training and promote the collaboration and networking between European psychiatric trainees. Methods: Member associations constitute the general assembly that meets annually during the European Forum of Psychiatric Trainees. During the Forum, working groups are created and the activities for the next year are planned. Results: Regular activities of the EFPT include the production of statements expressing the standpoint of trainees on educational issues, the conduction of research projects, the creation of new national trainees' associations, the facilitation of networking among European psychiatric trainees and the organization an annual meeting (EFPT Forum). The last EFPT Forum has been organized in Sorrento (Italy) on May 2012. Psychiatric trainees from 37 European countries have registered to this event. Discussion: EFPT activities constitute a opportunity for psychiatric trainees to directly participate in the improvement of their psychiatric training and to establish a network with European colleagues that will contribute to their professonal development.

Aims and Method Many studies report prescribing preferences for antipsychotics but few have examined what professionals would choose for themselves if they were diagnosed with schizophrenia. We asked 188 nurses, pharmacists and doctors which antipsychotic they would prefer to be prescribed. Results Risperidone ( n =49, 26.1%), olanzapine ( n =49, 26.1%) and aripiprazole ( n =35, 18.6%) were the most popular choices. Clinical Implications Professionals' choice was in line with the latest evidence on comparative effectiveness of atypical antipsychotics and therefore might be a sensitive indicator of the most effective antipsychotic.

Atypical (second-generation) antipsychotics are considered standard treatment for children and adolescents with early-onset schizophrenia and schizoaffective disorder. However, the superiority of second-generation antipsychotics over first-generation antipsychotics has not been demonstrated. This study compared the efficacy and safety of two second-generation antipsychotics (olanzapine and risperidone) with a first-generation antipsychotic (molindone) in the treatment of early-onset schizophrenia and schizoaffective disorder. This double-blind multisite trial randomly assigned pediatric patients with early-onset schizophrenia and schizoaffective disorder to treatment with either olanzapine (2.5-20 mg/day), risperidone (0.5-6 mg/day), or molindone (10-140 mg/day, plus 1 mg/day of benztropine) for 8 weeks. The primary outcome was response to treatment, defined as a Clinical Global Impression (CGI) improvement score of 1 or 2 and >or=20% reduction in Positive and Negative Syndrome Scale (PANSS) total score after 8 weeks of treatment. In total, 119 youth were randomly assigned to treatment. Of these subjects, 116 received at least one dose of treatment and thus were available for analysis. No significant differences were found among treatment groups in response rates (molindone: 50%; olanzapine: 34%; risperidone: 46%) or magnitude of symptom reduction. Olanzapine and risperidone were associated with significantly greater weight gain. Olanzapine showed the greatest risk of weight gain and significant increases in fasting cholesterol, low density lipoprotein, insulin, and liver transaminase levels. Molindone led to more self-reports of akathisia. Risperidone and olanzapine did not demonstrate superior efficacy over molindone for treating early-onset schizophrenia and schizoaffective disorder. Adverse effects were frequent but differed among medications. The results question the nearly exclusive use of second-generation antipsychotics to treat early-onset schizophrenia and schizoaffective disorder. The safety findings related to weight gain and metabolic problems raise important public health concerns, given the widespread use of second-generation antipsychotics in youth for nonpsychotic disorders.

The authors sought to determine the efficacy and acceptability of lithium for relapse prevention in bipolar disorder. A systematic review and meta-analysis of randomized controlled trials comparing lithium with placebo in the long-term treatment of bipolar disorders was conducted. Data were obtained from searching the registers of the Cochrane Collaboration; reviewing reference lists, journals, and conference abstracts; and contacting authors, experts, and pharmaceutical companies. Outcomes investigated included risk of relapse (manic, depressive, and total) as well as risk of specific adverse effects and total withdrawal rates. Five randomized controlled trials (770 participants) were included. Lithium was more effective than placebo in preventing all relapses (random effects relative risk=0.65, 95% CI=0.50 to 0.84) and manic relapses (relative risk=0.62, 95% CI=0.40 to 0.95). The protective effect of lithium on depressive relapses was smaller and was less robust (relative risk=0.72, 95% CI=0.49 to 1.07). Lithium treatment reduces the risk of relapse in bipolar disorder. The preventive effect is clear for manic episodes, although it is equivocal for depressive episodes.

The influence of patient and physician variables on antipsychotic drug choice for patients with schizophrenia was assessed. Interviews with 100 psychiatrists on drug choice for 200 patients suffering from schizophrenia were conducted. Data were analyzed by using multiple logistic regression. Older physicians were up to five times more likely to prescribe first-generation antipsychotics. Patient variables did not influence treatment decisions significantly. There is an urgent need for more research on clinical decision making and quality management.

The relative effectiveness of second-generation (atypical) antipsychotic drugs as compared with that of older agents has been incompletely addressed, though newer agents are currently used far more commonly. We compared a first-generation antipsychotic, perphenazine, with several newer drugs in a double-blind study. A total of 1493 patients with schizophrenia were recruited at 57 U.S. sites and randomly assigned to receive olanzapine (7.5 to 30 mg per day), perphenazine (8 to 32 mg per day), quetiapine (200 to 800 mg per day), or risperidone (1.5 to 6.0 mg per day) for up to 18 months. Ziprasidone (40 to 160 mg per day) was included after its approval by the Food and Drug Administration. The primary aim was to delineate differences in the overall effectiveness of these five treatments. Overall, 74 percent of patients discontinued the study medication before 18 months (1061 of the 1432 patients who received at least one dose): 64 percent of those assigned to olanzapine, 75 percent of those assigned to perphenazine, 82 percent of those assigned to quetiapine, 74 percent of those assigned to risperidone, and 79 percent of those assigned to ziprasidone. The time to the discontinuation of treatment for any cause was significantly longer in the olanzapine group than in the quetiapine (P<0.001) or risperidone (P=0.002) group, but not in the perphenazine (P=0.021) or ziprasidone (P=0.028) group. The times to discontinuation because of intolerable side effects were similar among the groups, but the rates differed (P=0.04); olanzapine was associated with more discontinuation for weight gain or metabolic effects, and perphenazine was associated with more discontinuation for extrapyramidal effects. The majority of patients in each group discontinued their assigned treatment owing to inefficacy or intolerable side effects or for other reasons. Olanzapine was the most effective in terms of the rates of discontinuation, and the efficacy of the conventional antipsychotic agent perphenazine appeared similar to that of quetiapine, risperidone, and ziprasidone. Olanzapine was associated with greater weight gain and increases in measures of glucose and lipid metabolism.

Second-generation (atypical) antipsychotics (SGAs) are more expensive than first-generation (typical) antipsychotics (FGAs) but are perceived to be more effective, with fewer adverse effects, and preferable to patients. Most evidence comes from short-term efficacy trials of symptoms. To test the hypothesis that in people with schizophrenia requiring a change in treatment, SGAs other than clozapine are associated with improved quality of life across 1 year compared with FGAs. A noncommercially funded, pragmatic, multisite, randomized controlled trial of antipsychotic drug classes, with blind assessments at 12, 26, and 56 weeks using intention-to-treat analysis. Fourteen community psychiatric services in the English National Health Service. Two hundred twenty-seven people aged 18 to 65 years with DSM-IV schizophrenia and related disorders assessed for medication review because of inadequate response or adverse effects. Randomized prescription of either FGAs or SGAs (other than clozapine), with the choice of individual drug made by the managing psychiatrist. Quality of Life Scale scores, symptoms, adverse effects, participant satisfaction, and costs of care. The primary hypothesis of significant improvement in Quality of Life Scale scores during the year after commencement of SGAs vs FGAs was excluded. Participants in the FGA arm showed a trend toward greater improvements in Quality of Life Scale and symptom scores. Participants reported no clear preference for either drug group; costs were similar. In people with schizophrenia whose medication is changed for clinical reasons, there is no disadvantage across 1 year in terms of quality of life, symptoms, or associated costs of care in using FGAs rather than nonclozapine SGAs. Neither inadequate power nor patterns of drug discontinuation accounted for the result.

The subdivision of the class of antipsychotic drugs into two discrete groups – ‘conventional’ (or first generation) and ‘atypical’ (or second generation) – has been adopted as standard, with the latter generally accepted as ‘better’ and widely recommended as automatic first-line choices. However, this perception has been thrown into confusion with the results of large pragmatic trials that failed to identify advantages with the new, more expensive drugs, while identifying worrying tolerability issues. This article explores the origins of ‘atypicality’, its construction on the back of a confusing and weak clinical validator (diminished liability to promote parkinsonism) and how even in relation to the archetypical atypical, clozapine, the uncertain boundaries of drug-induced extrapyramidal dysfunction may be contributing to confusion about ‘efficacy’ and ‘tolerability’. It argues that abandoning atypicality would open up clinical practice to all drugs of a single class of ‘antipsychotics’ and allow for individualised risk/benefit appraisal as a basis for truly tailored treatment recommendations.

Conventional meta-analyses have shown inconsistent results for efficacy of second-generation antidepressants. We therefore did a multiple-treatments meta-analysis, which accounts for both direct and indirect comparisons, to assess the effects of 12 new-generation antidepressants on major depression. We systematically reviewed 117 randomised controlled trials (25 928 participants) from 1991 up to Nov 30, 2007, which compared any of the following antidepressants at therapeutic dose range for the acute treatment of unipolar major depression in adults: bupropion, citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, milnacipran, mirtazapine, paroxetine, reboxetine, sertraline, and venlafaxine. The main outcomes were the proportion of patients who responded to or dropped out of the allocated treatment. Analysis was done on an intention-to-treat basis. Mirtazapine, escitalopram, venlafaxine, and sertraline were significantly more efficacious than duloxetine (odds ratios [OR] 1.39, 1.33, 1.30 and 1.27, respectively), fluoxetine (1.37, 1.32, 1.28, and 1.25, respectively), fluvoxamine (1.41, 1.35, 1.30, and 1.27, respectively), paroxetine (1.35, 1.30, 1.27, and 1.22, respectively), and reboxetine (2.03, 1.95, 1.89, and 1.85, respectively). Reboxetine was significantly less efficacious than all the other antidepressants tested. Escitalopram and sertraline showed the best profile of acceptability, leading to significantly fewer discontinuations than did duloxetine, fluvoxamine, paroxetine, reboxetine, and venlafaxine. Clinically important differences exist between commonly prescribed antidepressants for both efficacy and acceptability in favour of escitalopram and sertraline. Sertraline might be the best choice when starting treatment for moderate to severe major depression in adults because it has the most favourable balance between benefits, acceptability, and acquisition cost.

Because of the debate about whether second-generation antipsychotic drugs are better than first-generation antipsychotic drugs, we did a meta-analysis of randomised controlled trials to compare the effects of these two types of drugs in patients with schizophrenia. We compared nine second-generation antipsychotic drugs with first-generation drugs for overall efficacy (main outcome), positive, negative and depressive symptoms, relapse, quality of life, extrapyramidal side-effects, weight gain, and sedation. We included 150 double-blind, mostly short-term, studies, with 21 533 participants. We excluded open studies because they systematically favoured second-generation drugs. Four of these drugs were better than first-generation antipsychotic drugs for overall efficacy, with small to medium effect sizes (amisulpride -0.31 [95% CI -0.44 to -0.19, p<0.0001], clozapine -0.52 [-0.75 to -0.29, p<0.0001], olanzapine -0.28 [-0.38 to -0.18, p<0.0001], and risperidone -0.13 [-0.22 to -0.05, p=0.002]). The other second-generation drugs were not more efficacious than the first-generation drugs, even for negative symptoms. Therefore efficacy on negative symptoms cannot be a core component of atypicality. Second-generation antipsychotic drugs induced fewer extrapyramidal side-effects than did haloperidol (even at low doses). Only a few have been shown to induce fewer extrapyramidal side-effects than low-potency first-generation antipsychotic drugs. With the exception of aripiprazole and ziprasidone, second-generation antipsychotic drugs induced more weight gain, in various degrees, than did haloperidol but not than low-potency first-generation drugs. The second-generation drugs also differed in their sedating properties. We did not note any consistent effects of moderator variables, such as industry sponsorship, comparator dose, or prophylactic antiparkinsonian medication. Second-generation antipsychotic drugs differ in many properties and are not a homogeneous class.

Psychiatrists should be asked which neuroleptic they would prefer for themselves and their relatives in the case of first manifestation of schizophrenia. Questionnaires were answered by 66 psychiatrists from 13 different sites in Baden-Wuerttemberg (South West Germany). Only those were included who had treated more than 50 patients with schizophrenia within the last 5 years (n = 54). The psychiatrists were experienced with conventional and most of the atypical agents. Fifty-one point nine percent would take olanzapine as first line treatment, 20.4% risperidone, 13.0% quetiapine, 9.3% amisulpride, 3.7% haloperidol and 1.9% perazine. In four cases, different substances were preferred for oneself and relatives. Most psychiatrists would not take conventional neuroleptics, though 70% of prescriptions for schizophrenic patients have been conventional neuroleptics in Germany in 2000. The preferences among atypicals correspond well with the current prescription practice in Germany.
