Are guidelines in need of CPR? The development of clinical practice recommendations (CPR)

Getting depression clinical practice guidelines right: time for change?

OBJECTIVE

As part of a series of papers ['Chronobiology of mood disorders' Malhi & Kuiper. Acta Psychiatr Scand 2013;128(Suppl. 444):2-15; and 'It's time we managed depression: The emerging role of chronobiology' Malhi et al. Acta Psychiatr Scand 2013;128(Suppl. 444):1] examining chronobiology in the context of depression, this article examines recent western clinical practice guidelines (CPGs) for the treatment of depression with respect to the recommendations they make, in particular as regards chronobiological treatments, and briefly considers the implications of their methodology and approach.

METHOD

Five international treatment guidelines, which had been published in the past 5 years, were identified, representing North American and European views. Chosen guidelines were reviewed by the authors, and the relevant recommendations were distributed for discussion and subsequent synthesis.

RESULTS

Most current guidelines do not address chronobiology in detail. Chronotherapeutic recommendations are tentative, although agomelatine is considered as an option for major depression and bright light therapy for seasonal affective disorder. Sleep deprivation is not routinely recommended.

CONCLUSION

Recommendations are limited by the lack of reliable therapeutic markers for chronotherapeutics. Current evidence supports use of light therapy in seasonal depression, but in non-seasonal depression there is insufficient evidence to support reliance on chronotherapeutics over existing treatment modalities.

Balanced efficacy, safety, and tolerability recommendations for the clinical management of bipolar disorder

OBJECTIVE

To provide practical and clinically meaningful treatment recommendations that amalgamate clinical experience and research findings for each phase of bipolar disorder.

METHODS

A comprehensive search of the literature was undertaken using electronic database search engines (Medline, PubMed, Cochrane reviews) using key words (e.g., bipolar depression, mania, treatment). All relevant randomised controlled trials were examined, along with review papers, meta-analyses, and book chapters known to the authors. In addition, the recommendations from accompanying papers in this supplement have been distilled and captured in the form of summary boxes. The findings, in conjunction with the clinical experience of international researchers and clinicians who are practiced in treating mood disorders, formed the basis of the treatment recommendations within this paper.

RESULTS

Balancing clinical experience with evidence informed and lead to the development of practical clinical recommendations that emphasise the importance of safety and tolerability alongside efficacy in the clinical management of bipolar disorder.

CONCLUSIONS

The current paper summarises the treatment recommendations relating to each phase of bipolar disorder while providing additional, evidence-based, practical insights. Medication-related side effects and monitoring strategies highlight the importance of safety and tolerability considerations, which, along with efficacy information, should be given equal merit.

The clinical management of bipolar disorder complexity using a stratified model

OBJECTIVE

To provide practical and clinically meaningful treatment recommendations that amalgamate clinical and research considerations for several common, and as yet understudied, bipolar disorder complex presentations, within the framework of a proposed stratified model.

METHODS

A comprehensive search of the literature was undertaken using electronic database search engines (Medline, PubMed, Web of Science) using key words (e.g., bipolar disorder, anxiety, rapid cycling, and subsyndromal). All relevant randomised controlled trials were examined, in addition to review papers, meta-analyses, and book chapters known to the authors. The findings formed the basis of the treatment recommendations within this paper.

RESULTS

In light of the many broad presentations of bipolar disorder, a stratified model of bipolar disorder complexity was developed to facilitate consideration of the myriad of complexities that can occur during the longitudinal course of illness and the appropriate selection of treatment. Evidence-based treatment recommendations are provided for the following bipolar disorder presentations: bipolar II disorder, subsyndromal symptoms, mixed states, rapid cycling, comorbid anxiety, comorbid substance abuse, and for the following special populations: young, elderly, and bipolar disorder around the time of pregnancy and birth. In addition, some key strategies for countering treatment non-response and alternative medication recommendations are provided.

CONCLUSIONS

Treatment recommendations for the more challenging presentations of bipolar disorder have historically received less attention, despite their prevalence. This review acknowledges the weaknesses in the current evidence base on which treatment recommendations are generally formulated, and additionally emphasises the need for high-quality research in this area. The stratified model provides a means for conceptualizing the complexity of many bipolar disorder presentations and considering their management.

Atypical antipsychotic-induced mania/hypomania: a review of recent case reports and clinical studies

OBJECTIVE

Numerous case reports (53 between 1994 and 2003) caused concern with manic/hypomanic symptoms induced by atypical antipsychotic (AA) drugs. Its clinical relevance and causal link with AA antidepressant properties are largely unknown.

METHOD

We reviewed newly reported cases and clinical studies of AA-induced mania/hypomania between 2004 and 2010 in order to assess its prevalence and relation with mood disorders. Published studies were found through systematic database search (PubMed, Scirus, EMBASE, Cochrane Library, Science Direct).

RESULTS

Our search disclosed 28 new cases of AA-induced manic or hypomanic symptoms, following treatment with olanzapine (seven cases), quetiapine (five cases), ziprasidone (five cases), aripiprazole (four cases), amisulpride (two cases), zotepine (two cases), perospirone (two cases) and paliperidone (one case). Twenty-four patients suffered from schizophrenia; only four had schizoaffective disorder. Only one of the five cases of mania/hypomania with ziprasidone was a patient with mood disorder. Four well-designed clinical trials in bipolar depression included AA-induced mania/hypomania as a secondary outcome (three with quetiapine and one with olanzapine) and showed non-superiority relative to placebo.

CONCLUSIONS

Thus, well-designed clinical trials suggest that AA-induced mania/hypomania is a marginal phenomenon. Moreover, in most of the 28 new reported cases, AAs do not seem to induce mania/hypomania via their antidepressant properties.

Adherence to guidelines by French psychiatrists in their real world of clinical practice

The treatment modalities of bipolar disorder and adherence to international guidelines recommendations in France were investigated. We conducted an observational survey among 210 French psychiatrists concerning their prescribing practice in bipolar disorder, and whether they use guidelines or not. Simple mania is mainly treated with valproate, whereas second-generation antipsychotics are preferred for delusional mania. Lithium is mostly used as second-line treatment by "young psychiatrists." Personal experience appears in the foreground (41% of psychiatrists) in the choice of therapy. Young psychiatrists refer more to guidelines (32% of responders) as compared with other psychiatrists. The main reason for the lack of use of guidelines is because they refer mostly to an Anglo-Saxon medical practice, which is considered different from the French practice. Guidelines for treatment of bipolar disorder are not frequently used. French psychiatrists' age and practice type are the most important variables correlated to the level of use of guidelines.

Is lithium in a class of its own? A brief profile of its clinical use

Lithium is a unique and effective psychotropic agent with a long-standing history of clinical use yet it is increasingly overlooked in lieu of newer agents. The purpose of the present paper was to succinctly review the therapeutic profile of lithium particularly with respect to the treatment of mood disorders and consider its unique properties and clinical utility. A comprehensive literature review pertaining to lithium was undertaken using electronic database search engines to identify relevant clinical trials, meta-analyses and Cochrane reviews. In addition articles and book chapters known to the authors were carefully reviewed, and the authors appraised published guidelines. The evidence from these sources was rated using National Health and Medical Research Council evidence levels and synthesized according to phenotype and mood states. In addition, the authors have drawn upon published guidelines and their own clinical experience. Lithium has specificity for mood disorders with proven efficacy in the treatment of both unipolar depression and bipolar disorder. The recommendations are based predominantly on Level I evidence, but its clinical use has to be tempered against potential side-effects and the need for ongoing monitoring. In practice, lithium should be considered a first-line option in bipolar disorder, especially in prophylaxis and when onset of action is not an imperative. Lithium has been in use in modern medicine for 60 years and as such has been tried and tested across the full range of mood disorders. Arguably, lithium is the only true mood stabilizer and because of its unique properties is in a class of its own.

Treatment-resistant bipolar depression: towards a new definition

OBJECTIVE

To summarize the conceptual and operational definitions of treatment-resistant bipolar depression and to review the evidence-based therapeutic options.

METHOD

Structured searches of PubMed, Index Medicus, Excerpta Medica and Psyclit conducted in December 2008.

RESULTS

Criteria for treatment resistance in bipolar depression are commonly based on concepts stemming from treatment resistance as defined for unipolar depression, an approach that proved to be inadequate. In fact, the addition of an ad hoc criterion based on lithium and other mood stabilizer unresponsiveness after reaching adequate plasma levels appears to be a patch that attempts to take into account the uniqueness of bipolar depression but fails to become operational. Recent data from randomized clinical trials of new anticonvulsants and second-generation antipsychotics should lead to the development of a modern definition of treatment-resistant bipolar depression, and specific therapeutic algorithms.

CONCLUSION

We suggest a redefinition of resistant bipolar I and II depression. We propose different degrees of severity within bipolar depression in a stepwise manner.

Clinical practice recommendations for bipolar disorder

OBJECTIVE

To provide clinically relevant evidence-based recommendations for the management of bipolar disorder in adults that are informative, easy to assimilate and facilitate clinical decision-making.

METHOD

A comprehensive literature review of over 500 articles was undertaken using electronic database search engines (e.g. MEDLINE, PsychINFO and Cochrane reviews). In addition articles, book chapters and other literature known to the authors were reviewed. The findings were then formulated into a set of recommendations that were developed by a multidisciplinary team of clinicians who routinely deal with mood disorders. These preliminary recommendations underwent extensive consultative review by a broader advisory panel that included experts in the field, clinical staff and patient representatives.

RESULTS

The clinical practice recommendations for bipolar disorder (bipolar CPR) summarise evidence-based treatments and provide a synopsis of recommendations relating to each phase of the illness. They are designed for clinical use and have therefore been presented succinctly in an innovative and engaging manner that is clear and informative.

CONCLUSION

These up-to-date recommendations provide an evidence-based framework that incorporates clinical wisdom and consideration of individual factors in the management of bipolar disorder. Further, the novel style and practical approach should promote their uptake and implementation.
