The derivation of a preference-based measure for people with common mental health problems from the Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM)

Background: Generic preference-based measures (PBMs), such as the EQ-5D and SF-6D, are widely used for the estimation of Quality Adjusted Life Years in cost-utility analyses of healthcare interventions. However, their relevance in some disease areas, including mental health, has been questioned. Objective of the thesis: To derive a PBM specific to mental health problems from an existing condition-specific measure (CSM) Methods: A systematic literature review was conducted to identify an appropriate CSM for the derivation of a health state classification. Derivation of the new measure was achieved using novel methodology developed for this purpose, due to the high correlation across the items of the original CSM. Selected health states were valued by members of the public. Regression analysis was employed to predict utility values for all states of the health state classification. Psychometric and qualitative assessments evaluated the performance of the new PBM compared with generic PBMs and the original CSM. Results: The Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM) was selected as the basis for the derivation of the new PBM. Application of novel methodology based primarily on Rasch analysis resulted in the development of CORE-6D, a health state classification that consists of a 5-item emotional component and a physical item. Rasch analysis was used to select plausible health states for valuation. A highly predictive regression model was used to attach utility values to all CORE-6D health states. The new PBM has shown promising results regarding its psychometric properties compared with generic PBMs and suffers from little loss of information relative to the original measure, CORE-OM. Further research needs to validate these findings. Conclusion: The CORE-6D preference-based index will enable cost-utility analysis of mental health interventions using existing and prospective CORE-OM datasets. The new methodology for deriving PBMs from existing instruments can be useful for the derivation of PBMs from other instruments with highly correlated dimensions

The Cost Effectiveness of Pharmacological Treatments for Generalized Anxiety Disorder

Background: Generalized anxiety disorder (GAD) is one of the most prevalent anxiety disorders, with important implications for patients and healthcare resources. However, few economic evaluations of pharmacological treatments for GAD have been published to date, and those available have assessed only a limited number of drugs. / Objective: To assess the cost effectiveness of pharmacological interventions for patients with GAD in the UK. / Methods: A decision-analytic model in the form of a decision tree was constructed to compare the costs and QALYs of six drugs used as first-line pharmacological treatments in people with GAD (duloxetine, escitalopram, paroxetine, pregabalin, sertraline and venlafaxine extended release [XL]) and ‘no pharmacological treatment’. The analysis adopted the perspective of the NHS and Personal Social Services (PSS) in the UK. Efficacy data were derived from a systematic literature review of double-blind, randomized controlled trials and were synthesized using network meta-analytic techniques. Two network meta-analyses were undertaken to assess the comparative efficacy (expressed by response rates) and tolerability (expressed by rates of discontinuation due to intolerable side effects) of the six drugs and no treatment in the study population. Cost data were derived from published literature and national sources, supplemented by expert opinion. The price year was 2011. Probabilistic sensitivity analysis was conducted to evaluate the underlying uncertainty of the model input parameters. / Results: Sertraline was the best drug in limiting discontinuation due to side effects and the second best drug in achieving response in patients not discontinuing treatment due to side effects. It also resulted in the lowest costs and highest number of QALYs among all treatment options assessed. Its probability of being the most cost-effective drug reached 75 % at a willingness-to-pay threshold of £20,000 per extra QALY gained. / Conclusion: Sertraline appears to be the most cost-effective drug in the treatment of patients with GAD. However, this finding is based on limited evidence for sertraline (two published trials). Sertraline is not licensed for the treatment of GAD in the UK, but is commonly used by primary care practitioners for the treatment of depression and mixed depression and anxiety

The Cost Effectiveness of Psychological and Pharmacological Interventions for Social Anxiety Disorder:A Model-Based Economic Analysis

Background Social anxiety disorder is one of the most persistent and common anxiety disorders. Individually delivered psychological therapies are the most effective treatment options for adults with social anxiety disorder, but they are associated with high intervention costs. Therefore, the objective of this study was to assess the relative cost effectiveness of a variety of psychological and pharmacological interventions for adults with social anxiety disorder. Methods A decision-analytic model was constructed to compare costs and quality adjusted life years (QALYs) of 28 interventions for social anxiety disorder from the perspective of the British National Health Service and personal social services. Efficacy data were derived from a systematic review and network meta-analysis. Other model input parameters were based on published literature and national sources, supplemented by expert opinion. Results Individual cognitive therapy was the most cost-effective intervention for adults with social anxiety disorder, followed by generic individual cognitive behavioural therapy (CBT), phenelzine and book-based self-help without support. Other drugs, group-based psychological interventions and other individually delivered psychological interventions were less cost-effective. Results were influenced by limited evidence suggesting superiority of psychological interventions over drugs in retaining long-term effects. The analysis did not take into account side effects of drugs. Conclusion Various forms of individually delivered CBT appear to be the most cost-effective options for the treatment of adults with social anxiety disorder. Consideration of side effects of drugs would only strengthen this conclusion, as it would improve even further the cost effectiveness of individually delivered CBT relative to phenelzine, which was the next most cost-effective option, due to the serious side effects associated with phenelzine. Further research needs to determine more accurately the long-term comparative benefits and harms of psychological and pharmacological interventions for social anxiety disorder and establish their relative cost effectiveness with greater certainty

Psychological and pharmacological interventions for social anxiety disorder in adults: a systematic review and network meta-analysis

SummaryBackgroundSocial anxiety disorder—a chronic and naturally unremitting disease that causes substantial impairment—can be treated with pharmacological, psychological, and self-help interventions. We aimed to compare these interventions and to identify which are most effective for the acute treatment of social anxiety disorder in adults.MethodsWe did a systematic review and network meta-analysis of interventions for adults with social anxiety disorder, identified from published and unpublished sources between 1988 and Sept 13, 2013. We analysed interventions by class and individually. Outcomes were validated measures of social anxiety, reported as standardised mean differences (SMDs) compared with a waitlist reference. This study is registered with PROSPERO, number CRD42012003146.FindingsWe included 101 trials (13 164 participants) of 41 interventions or control conditions (17 classes) in the analyses. Classes of pharmacological interventions that had greater effects on outcomes compared with waitlist were monoamine oxidase inhibitors (SMD −1·01, 95% credible interval [CrI] −1·56 to −0·45), benzodiazepines (−0·96, −1·56 to −0·36), selective serotonin-reuptake inhibitors and serotonin–norepinephrine reuptake inhibitors (SSRIs and SNRIs; −0·91, −1·23 to −0·60), and anticonvulsants (−0·81, −1·36 to −0·28). Compared with waitlist, efficacious classes of psychological interventions were individual cognitive–behavioural therapy (CBT; SMD −1·19, 95% CrI −1·56 to −0·81), group CBT (−0·92, −1·33 to −0·51), exposure and social skills (−0·86, −1·42 to −0·29), self-help with support (−0·86, −1·36 to −0·36), self-help without support (−0·75, −1·25 to −0·26), and psychodynamic psychotherapy (−0·62, −0·93 to −0·31). Individual CBT compared with psychological placebo (SMD −0·56, 95% CrI −1·00 to −0·11), and SSRIs and SNRIs compared with pill placebo (−0·44, −0·67 to −0·22) were the only classes of interventions that had greater effects on outcomes than appropriate placebo. Individual CBT also had a greater effect than psychodynamic psychotherapy (SMD −0·56, 95% CrI −1·03 to −0·11) and interpersonal psychotherapy, mindfulness, and supportive therapy (−0·82, −1·41 to −0·24).InterpretationIndividual CBT (which other studies have shown to have a lower risk of side-effects than pharmacotherapy) is associated with large effect sizes. Thus, it should be regarded as the best intervention for the initial treatment of social anxiety disorder. For individuals who decline psychological intervention, SSRIs show the most consistent evidence of benefit.FundingNational Institute for Health and Care Excellence

Cost-effectiveness of psychological interventions for children and young people with post-traumatic stress disorder

Background: PTSD in youth may lead to long-lasting psychological implications, educational difficulties and increased healthcare costs. Psychological interventions have been shown to be effective in its management. The objective of this study was to assess the cost-effectiveness of a range of psychological interventions for children and young people with PTSD. Methods: A decision-analytic model was constructed to compare costs and quality-adjusted life years (QALYs) of 10 psychological interventions and no treatment for children and young people with PTSD, from the perspective of the National Health Service and personal social services in England. Effectiveness data were derived from a systematic review and network meta-analysis. Other model input parameters were based on published sources, supplemented by expert opinion. Results: Cognitive therapy for PTSD, a form of individual trauma-focused cognitive behavioural therapy (TF-CBT), appeared to be the most cost-effective intervention for children and young people with PTSD (with a probability of.78 amongst the 11 evaluated options at a cost-effectiveness threshold of £20,000/QALY), followed by narrative exposure (another form of individual TF-CBT), play therapy, and other forms of individual TF-CBT. After excluding cognitive therapy from the analysis, narrative exposure appeared to be the most cost-effective option with a.40 probability of being cost-effective amongst the remaining 10 options. EMDR, parent training and group TF-CBT occupied middle cost-effectiveness rankings. Family therapy and supportive counselling were less cost-effective than other active interventions. There was limited evidence for some interventions, in particular cognitive therapy for PTSD and parent training. Conclusions: Individual forms of TF-CBT and, to a lesser degree, play therapy appear to be cost-effective in the treatment of children and young people with PTSD. Family therapy and supportive counselling are unlikely to be cost-effective relative to other interventions. There is a need for well-conducted studies that examine the long-term clinical and cost-effectiveness of a range of psychological treatments for children and young people with PTSD

Research Review: Psychological and psychosocial treatments for children and young people with post-traumatic stress disorder : a network meta-analysis

Background : Post-traumatic stress disorder (PTSD) is a potentially chronic and disabling disorder that affects a significant minority of youth exposed to trauma. Previous studies have concluded that trauma-focused cognitive behavioural therapy (TF-CBT) is an effective treatment for PTSD in youth, but the relative strengths of different psychological therapies are poorly understood. Methods : We undertook a systematic review and network meta-analyses of psychological and psychosocial interventions for children and young people with PTSD. Outcomes included PTSD symptom change scores post-treatment and at 1-4-month follow-up, and remission post-treatment. Results : We included 32 trials of 17 interventions and 2,260 participants. Overall, the evidence was of moderate-to-low quality. No inconsistency was detected between direct and indirect evidence. Individual forms of TF-CBT showed consistently large effects in reducing PTSD symptoms post-treatment compared with waitlist. The order of interventions by descending magnitude of effect versus waitlist was: cognitive therapy for PTSD (SMD -2.94, 95%CrI -3.94 to -1.95), combined somatic/cognitive therapies, child-parent psychotherapy, combined TF-CBT/parent training, meditation, narrative exposure, exposure/prolonged exposure, play therapy, Cohen TF-CBT/cognitive processing therapy (CPT), eye movement desensitisation and reprocessing (EMDR), parent training, group TF-CBT, supportive counselling, and family therapy (SMD -0.37, 95%CrI -1.60 to 0.84). Results for parent training, supportive counselling and family therapy were inconclusive. Cohen TF-CBT/CPT, group TF-CBT and supportive counselling had the largest evidence base. Results regarding changes in PTSD symptoms at follow-up and remission post-treatment were uncertain due to limited evidence. Conclusions : TF-CBT, in particular individual forms, appears to be most effective in the management of PTSD in youth. EMDR is effective but to a lesser extent. Supportive counselling does not appear to be effective. Results suggest a large positive effect for emotional freedom technique, child-parent psychotherapy, combined TF-CBT/parent training, and meditation, but further research is needed to confirm these findings as they were based on very limited evidence

Cost-effectiveness of topical pharmacological, oral pharmacological, physical and combined treatments for acne vulgaris

Background. Acne vulgaris is a common skin condition that may cause psychoso-cial distress. There is evidence that topical treatment combinations, chemical peels and photochemical therapy (combined blue/red light) are effective for mild-to-moderate acne, while topical treatment combinations, oral antibiotics combined with topical treatments, oral isotretinoin and photodynamic therapy are most effective for moderate-to-severe acne. Effective treatments have varying costs. The National Institute for Health and Care Excellence (NICE) in England considers cost-effectiveness when producing national clinical, public health and social care guidance.Aim: To assess the cost-effectiveness of treatments for mild-to-moderate and moderate-to-severe acne to inform relevant NICE guidance.Methods: A decision–analytical model compared costs and quality-adjusted life-years (QALYs) of effective topical pharmacological, oral pharmacological, physical and combined treatments for mild-to-moderate and moderate-to-severe acne, from the perspective of the National Health Service in England. Effectiveness data were derived from a network meta-analysis. Other model input parameters were based on published sources, supplemented by expert opinion.Results: All of the assessed treatments were more cost-effective than treatment with placebo (general practitioner visits without active treatment). For mild-to-moderate acne, topical treatment combinations and photochemical therapy (com-bined blue/red light) were most cost-effective. For moderate-to-severe acne, topical treatment combinations, oral antibiotics combined with topical treatments, and oral isotretinoin were the most cost-effective. Results showed uncertainty, as reflected in the wide confidence intervals around mean treatment rankings.Conclusion: A range of treatments are cost-effective for the management of acne. Well-conducted studies are needed to examine the long-term clinical efficacy and cost-effectiveness of the full range of acne treatments

Cost-effectiveness of psychological treatments for post-traumatic stress disorder in adults

BackgroundPost-traumatic stress disorder (PTSD) is a severe and disabling condition that may lead to functional impairment and reduced productivity. Psychological interventions have been shown to be effective in its management. The objective of this study was to assess the cost-effectiveness of a range of interventions for adults with PTSD.MethodsA decision-analytic model was constructed to compare costs and quality-adjusted life-years (QALYs) of 10 interventions and no treatment for adults with PTSD, from the perspective of the National Health Service and personal social services in England. Effectiveness data were derived from a systematic review and network meta-analysis. Other model input parameters were based on published sources, supplemented by expert opinion.ResultsEye movement desensitisation and reprocessing (EMDR) appeared to be the most cost-effective intervention for adults with PTSD (with a probability of 0.34 amongst the 11 evaluated options at a cost-effectiveness threshold of £20,000/QALY), followed by combined somatic/cognitive therapies, self-help with support, psychoeducation, selective serotonin reuptake inhibitors (SSRIs), trauma-focused cognitive behavioural therapy (TF-CBT), self-help without support, non-TF-CBT and combined TF-CBT/SSRIs. Counselling appeared to be less cost-effective than no treatment. TF-CBT had the largest evidence base.ConclusionsA number of interventions appear to be cost-effective for the management of PTSD in adults. EMDR appears to be the most cost-effective amongst them. TF-CBT has the largest evidence base. There remains a need for well-conducted studies that examine the long-term clinical and cost-effectiveness of a range of treatments for adults with PTSD

Using Rasch analysis to form plausible health states amenable to valuation: the development of CORE-6D from CORE-OM in order to elicit preferences for common mental health problems

Purpose: To describe a new approach for deriving a preference-based index from a condition specific measure that uses Rasch analysis to develop health states. Methods: CORE-OM is a 34-item instrument monitoring clinical outcomes of people with common mental health problems. CORE-OM is characterised by high correlation across its domains. Rasch analysis was used to reduce the number of items and response levels in order to produce a set of unidimensionally-behaving items, and to generate a credible set of health states corresponding to different levels of symptom severity using the Rasch item threshold map. Results: The proposed methodology resulted in the development of CORE-6D, a 2-dimensional health state description system consisting of a unidimensionally-behaving 5-item emotional component and a physical symptom item. Inspection of the Rasch item threshold map of the emotional component helped identify a set of 11 plausible health states, which, combined with the physical symptom item levels, will be used for the valuation of the instrument, resulting in the development of a preference-based index. Conclusions: This is a useful new approach to develop preference-based measures where the domains of a measure are characterised by high correlation. The CORE-6D preference-based index will enable calculation of Quality Adjusted Life Years in people with common mental health problems

Psychological treatments for post-traumatic stress disorder in adults: : a network meta-analysis

BACKGROUND: Post-traumatic stress disorder (PTSD) is a potentially chronic and disabling disorder affecting a significant minority of people exposed to trauma. Various psychological treatments have been shown to be effective, but their relative effects are not well established. METHODS: We undertook a systematic review and network meta-analyses of psychological interventions for adults with PTSD. Outcomes included PTSD symptom change scores post-treatment and at 1-4-month follow-up, and remission post-treatment. RESULTS: We included 90 trials, 6560 individuals and 22 interventions. Evidence was of moderate-to-low quality. Eye movement desensitisation and reprocessing (EMDR) [standardised mean difference (SMD) -2.07; 95% credible interval (CrI) -2.70 to -1.44], combined somatic/cognitive therapies (SMD -1.69; 95% CrI -2.66 to -0.73), trauma-focused cognitive behavioural therapy (TF-CBT) (SMD -1.46; 95% CrI -1.87 to -1.05) and self-help with support (SMD -1.46; 95% CrI -2.33 to -0.59) appeared to be most effective at reducing PTSD symptoms post-treatment v. waitlist, followed by non-TF-CBT, TF-CBT combined with a selective serotonin reuptake inhibitor (SSRI), SSRIs, self-help without support and counselling. EMDR and TF-CBT showed sustained effects at 1-4-month follow-up. EMDR, TF-CBT, self-help with support and counselling improved remission rates post-treatment. Results for other interventions were either inconclusive or based on limited evidence. CONCLUSIONS: EMDR and TF-CBT appear to be most effective at reducing symptoms and improving remission rates in adults with PTSD. They are also effective at sustaining symptom improvements beyond treatment endpoint. Further research needs to explore the long-term comparative effectiveness of psychological therapies for adults with PTSD and also the impact of severity and complexity of PTSD on treatment outcomes
