Psychological interventions for adults with asthma

Basis of preventive and non-pharmacological interventions in asthma

Asthma is one of the most common atopic disorders in all stages of life. Its etiology is likely due to a complex interaction between genetic, environmental, and lifestyle factors. Due to this, different non-pharmacological interventions can be implemented to reduce or alleviate the symptoms caused by this disease. Thus, the present narrative review aimed to analyze the preventive and non-pharmacological interventions such as physical exercise, physiotherapy, nutritional, ergonutritional, and psychological strategies in asthma treatment. To reach these aims, an extensive narrative review was conducted. The databases used were MedLine (PubMed), Cochrane (Wiley), Embase, PsychINFO, and CinAhl. Asthma is an immune-mediated inflammatory condition characterized by increased responsiveness to bronchoconstrictor stimuli. Different factors have been shown to play an important role in the pathogenesis of asthma, however, the treatments used to reduce its incidence are more controversial. Physical activity is focused on the benefits that aerobic training can provide, while physiotherapy interventions recommend breathing exercises to improve the quality of life of patients. Nutritional interventions are targeted on implement diets that prioritize the consumption of fruits and vegetables and supplementation with antioxidants. Psychological interventions have been proposed as an essential non-pharmacological tool to reduce the emotional problems associated with asthma.

Non-randomised feasibility study testing a primary care intervention to promote engagement in an online health community for adults with troublesome asthma: protocol

INTRODUCTION

In the UK, approximately 4.3 million adults have asthma, with one-third experiencing poor asthma control, affecting their quality of life, and increasing their healthcare use. Interventions promoting emotional/behavioural self-management can improve asthma control and reduce comorbidities and mortality. Integration of online peer support into primary care services to foster self-management is a novel strategy. We aim to co-design and evaluate an intervention for primary care clinicians to promote engagement with an asthma online health community (OHC). Our protocol describes a 'survey leading to a trial' design as part of a mixed-methods, non-randomised feasibility study to test the feasibility and acceptability of the intervention.

METHODS AND ANALYSIS

Adults on the asthma registers of six London general practices (~3000 patients) will be invited to an online survey, via text messages. The survey will collect data on attitudes towards seeking online peer support, asthma control, anxiety, depression, quality of life, information on the network of people providing support with asthma and demographics. Regression analyses of the survey data will identify correlates/predictors of attitudes/receptiveness towards online peer support. Patients with troublesome asthma, who (in the survey) expressed interest in online peer support, will be invited to receive the intervention, aiming to reach a recruitment target of 50 patients. Intervention will involve a one-off, face-to-face consultation with a practice clinician to introduce online peer support, sign patients up to an established asthma OHC, and encourage OHC engagement. Outcome measures will be collected at baseline and 3 months post intervention and analysed with primary care and OHC engagement data. Recruitment, intervention uptake, retention, collection of outcomes, and OHC engagement will be assessed. Interviews with clinicians and patients will explore experiences of the intervention.

ETHICS AND DISSEMINATION

Ethical approval was obtained from a National Health Service Research Ethics Committee (reference: 22/NE/0182). Written consent will be obtained before intervention receipt and interview participation. Findings will be shared via dissemination to general practices, conference presentations and peer-reviewed publications.

Multimorbidity in Difficult Asthma: The Need for Personalised and Non-Pharmacological Approaches to Address a Difficult Breathing Syndrome

Three to ten percent of people living with asthma have difficult-to-treat asthma that remains poorly controlled despite maximum levels of guideline-based pharmacotherapy. This may result from a combination of multiple adverse health issues including aggravating comorbidities, inadequate treatment, suboptimal inhaler technique and/or poor adherence that may individually or collectively contribute to poor asthma control. Many of these are potentially "treatable traits" that can be pulmonary, extrapulmonary, behavioural or environmental factors. Whilst evidence-based guidelines lead clinicians in pharmacological treatment of pulmonary and many extrapulmonary traits, multiple comorbidities increase the burden of polypharmacy for the patient with asthma. Many of the treatable traits can be addressed with non-pharmacological approaches. In the current healthcare model, these are delivered by separate and often disjointed specialist services. This leaves the patients feeling lost in a fragmented healthcare system where clinical outcomes remain suboptimal even with the best current practice applied in each discipline. Our review aims to address this challenge calling for a paradigm change to conceptualise difficult-to-treat asthma as a multimorbid condition of a "Difficult Breathing Syndrome" that consequently needs a holistic personalised care attitude by combining pharmacotherapy with the non-pharmacological approaches. Therefore, we propose a roadmap for an evidence-based multi-disciplinary stepped care model to deliver this.

The Management of Extrapulmonary Comorbidities and Treatable Traits; Obesity, Physical Inactivity, Anxiety, and Depression, in Adults With Asthma

Asthma is a complex and heterogenous disease characterized by variability in disease expression and severity. Multiple extrapulmonary comorbidities and treatable traits are common in people with asthma, and there is an increasing appreciation of how these may complicate asthma management. This review will discuss the prevalence and impact of extrapulmonary comorbidities/risk factors or "traits," which have been found to co-exist in asthma (obesity, symptoms of depression and/or anxiety and physical inactivity), the impact these traits have on future outcomes (including exacerbation risk and quality of life) and asthma management, and how we should target treatment in asthma when these extrapulmonary traits are present.

Impact of interventions targeting anxiety and depression in adults with asthma

OBJECTIVE

High rates of anxiety and depression exist among asthma patient populations. This scoping review will examine the existing interventional therapies that address depression and anxiety symptoms in patients with asthma.

DATA SOURCES

PubMed, Cochrane, Psychinfo, CINAHL, Google Scholar and EMBASE databases were searched using the following search terms: 'anxiety asthma', 'panic disorder asthma' and 'depression asthma' with a randomized clinical trial filter and additional filters to exclude exclusion criteria.

STUDY SELECTIONS

Study selections included only randomized control trials with anxiety and/or depression and/or panic disorder outcomes as primary or secondary outcomes. Only full-text articles in the English language were included.

RESULTS

This search yielded interventions from pharmacologic (n = 3), psychological (n = 7), lifestyle medicine (n = 10) and complementary and alternative medicine (CAM; n = 1) using a range of outcomes from physiologic to psychologic. While the pharmacologic and CAM studies were inconclusive, psychologic and lifestyle interventions showed improvements in asthma (quality of life, symptoms, asthma attacks) and psychological (anxiety, panic fear, depression) outcomes. Variations in selection methods, outcome measures and diagnostic criteria hindered a direct comparison of the studies. Most studies had small sample sizes, high attrition rates and short study durations.

CONCLUSION

There is limited evidence on best approaches for managing co-morbid anxiety and/or depression in patients with asthma. Psychological and lifestyle medicine interventions are promising with improvements in both asthma and mental health outcomes. Well-designed randomized controlled studies with larger sample sizes, standardized outcomes and longer durations, are needed to better understand the role of depression and anxiety in adults with asthma.

High Use of Antidepressant Medication in Both Mild-to-Modelate and Possible Severe Asthma - A Nationwide Cohort Study

PURPOSE

In asthma, increased severity has been linked to depression assessed as assessed by patient-reported outcomes. However, little is known about predictors of antidepressant use in asthma compared to the background population.

METHODS

The study consists of 60,534 asthma patients aged 18-45 and a 1:1 age- and sex-matched control group. Using national registries and prescription data, the prevalence of and risk factors for antidepressant use were investigated by logistic regression adjusted for age, sex, workforce and civil status, income- and education-level and comorbidity. Results presented as odds ratio (OR) with 95% confidence intervals (CI).

RESULTS

A total of 16% and 22%, respectively, among patients with mild-to-moderate and possible severe asthma redeemed antidepressant drugs, compared to 10% of controls. Antidepressant use was more prevalent amongst patients with high rescue medication use (>600 annual doses) and those with a history of moderate or severe exacerbation(s). Both mild-to-moderate and possible severe asthma were independent risk factors for antidepressant use (OR 1.40 (95% CI 1.35, 1.46) and OR 1.55 (95% CI 1.41, 1.70), respectively). Female sex, age, being divorced or never married, having only primary education or currently being under education, as well as being on welfare/transfer income increased odds of antidepressant use. Completing higher education and having high income were associated with lower odds.

CONCLUSION

In asthma, antidepressant use is significantly higher than in the background population. Even after adjusting for known risk factors, asthma remains a predictor of antidepressant use, signalling a psychologic burden related to living with asthma.

Psychological interventions for people with hemophilia

BACKGROUND

Managing hemophilia is challenging both in terms of medical treatment and its broad impact on many aspects of the individual's life, including self-perception. Several psychosocial issues are potentially relevant in the clinical management of hemophilia, including it being a chronic and incurable condition; e.g. people with hemophilia must adapt to optimally interact with peers and to practice sports - even choosing a sport represents an issue for perceived limitations, expectations and cultural influences on the individual and their family. People with hemophilia can react by denying their condition and its manifestations and not adhering to treatment. Due to the complexity of relationships surrounding genetic diseases, parents and relatives may have their own issues that contribute to making life easier or more difficult for the person with hemophilia. Anxiety, sadness and depression resulting in mental health disorders are reported in this population and may influence quality of life (QoL) depending on cultural background, religious beliefs, family support and other variables.

OBJECTIVES

Primarily to assess the effectiveness of psychological therapies for improving the ability of people with hemophilia to cope with their chronic condition.

SEARCH METHODS

We aimed to identify trials from the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register, Embase and PsycINFO, CINAHL, MEDLINE and trial registries. We searched reference lists of included publications. Most recent search of the Group's register: 13 June 2019.

SELECTION CRITERIA

Randomized controlled trials (RCTs) and quasi-RCTs in people with hemophilia of any age or gender, type A or B, any severity, with or without inhibitors, with or without HIV or hepatitis C virus. All psychological interventions for promoting emotional, intellectual and spiritual wellness. Individual, group or family group therapy interventions were eligible.

DATA COLLECTION AND ANALYSIS

We independently assessed trials, extracted data and assessed the risk of bias and assessed the quality of the evidence using GRADE.

MAIN RESULTS

Seven trials were included (362 participants randomized, data from 264 participants available for analysis); six of parallel design and one a partial cross-over design. One multicenter trial was conducted in Canada; the remaining six were single centre undertaken in the UK, USA, Iran and in the Netherlands. All trials had a high risk of bias for participant blinding and use of patient-reported outcomes. Evidence was retrieved on four interventions: psycho-education (DVD plus information booklet versus information booklet alone; computerised learning versus no intervention); cognitive therapy (auto-hypnosis (self-hypnosis) versus control); and behavioural therapy (relaxation (progressive or self control) versus no treatment). We also aimed to assess psychodynamic therapy and systemic therapy, but no trials were identified. Heterogeneity of the outcome measures and measurements precluded meta-analyses. No trial reported the cost of the psychological intervention and family adjustment. DVD plus information booklet compared to information booklet alone One trial (108 participants) showed coping strategies may lower pre-contemplation scores and negative thoughts, mean difference (MD) -0.24 (95%CI -0.48 - 0.00, low-certainty evidence), however, other measures of coping strategies in the same trial suggest little or no difference between groups, e.g. contemplation, MD (-0.09, 95%CI -0.32 - 0.14, low-certainty evidence). The same trial measured QoL and showed little or no difference between treatment groups for the physical domain, MD 0.59 (95% CI -3.66 to 4.84, low-certainty evidence), but may improve scores in the mental health domain for those receiving the booklet plus DVD compared to booklet alone, MD (4.70, 95% CI 0.33 to 9.07, low-certainty evidence). Mood or personal well-being were not reported. Computerised learning compared to no intervention Two trials (57 participants) reported on interventions aimed at children and adolescents and their impact on promoting a sense of self-efficacy (primary outcome 'Mood and personal well-being'), but only one showed an increase, MD 7.46 (95%CI 3.21 to 11.71, 17 participants, very low-certainty evidence); the second did not report control group data. One trial (30 participants) showed the intervention did not improve self-efficacy in adults, but appropriate data could not be extracted. Two trials (47 participants) reported coping strategies; one only reported within-group differences from baseline, the second showed an increase from baseline in coping strategies in the Internet program group compared to the no intervention group (disease-specific knowledge, MD 2.45 (95% CI 0.89 to 4.01); self-management ability and transition readiness, MD 19.90 (95% CI 3.61 to 36.19; low-certainty evidence). One trial reported QoL but with insufficient information to calculate changes from baseline; no difference in post-treatment scores was seen between groups, MD -8.65, 95% CI -18.30 to 1.00, very low-certainty evidence). Auto-hypnosis (self-hypnosis) compared to control There were two older trials that reported on this intervention (50 participants) focusing mainly on the secondary outcome 'physical health'; only one trial reported the primary outcome 'mood and personal well-being' (only within-group differences in the treatment group). Coping strategies and QoL were not assessed in the trials. Relaxation (progressive or self control) compared to no treatment Only one trial (seven participants) from 1985, was included which focused on 'physical health' and did not report on any of our primary outcomes.

AUTHORS' CONCLUSIONS

Not all of the seven included trials analysed the effects of the interventions on our primary outcomes (mood and personal well-being, coping strategies and QoL). Three trials were conducted in the 1970s and 1980s using techniques of auto-hypnosis or relaxation and, in accordance with the needs and therapeutic possibilities of the time, they focused on secondary outcomes, e.g. frequency of bleeding (physical health) and adherence to the intervention. The four newer trials assessed psycho-educational interventions all mediated by the use of technologies (DVD or computer) and often created according to age needs of the target group. In these cases, attention was shifted to our pre-defined primary outcomes. This review has identified low- and very low-certainty evidence, prompting caution in its interpretation. The major problem we encountered was the heterogeneity of trial designs, of interventions and of outcome measures used across the trials. We strongly suggest that researchers consider developing a core outcome set to streamline future research; randomization was proven to be safe and acceptable, and blinding should be considered for those assessing patient-reported outcomes.

Impact of non-drug therapies on asthma control: A systematic review of the literature

BACKGROUND

Despite growing access to effective therapies, asthma control still needs improvement. Many non-drug factors, such as allergens, air pollutants and stress also affect asthma control and patient quality of life, but an overview of the effectiveness of non-drug interventions on asthma control was lacking.

OBJECTIVES

To identify non-drug interventions likely to improve asthma control.

METHODS

A systematic review of the available literature in Medline and the Cochrane Library was conducted in March 2017, without any time limit. Initial searching identified 884 potentially relevant clinical trial reports, literature reviews and meta-analyses, which were screened for inclusion using criteria of quality, relevance, and reporting outcomes based on asthma control.

RESULTS

Eighty-two publications met the inclusion criteria. In general, the quality of the studies was low. Patient education programmes (22 studies) significantly improved asthma control. Multifaceted interventions (10 studies), which combined patient education programmes with decreasing exposure to indoor allergens and pollutants, significantly improved asthma control based on clinically relevant outcomes. Renovating homes to reduce exposure to allergens and indoor pollutants improved control (two studies). Air filtration systems (five studies) were effective, especially in children exposed to second-hand smoke. Most measures attempting to reduce exposure to dust mites were ineffective (five studies). Dietary interventions (eight studies) were ineffective. Promoting physical activity (five studies) tended to yield positive results, but the results did not attain significance.

CONCLUSION

Twenty-six interventions were effective in asthma control. Simultaneously combining several action plans, each focusing on different aspects of asthma management, seems most likely to be effective.

Dysfunctional Breathing in Children and Adults With Asthma

Asthma occurs across the life course. Its optimal treatment includes the use of personalized management plans that recognize the importance of co-morbidities including so-called "dysfunctional breathing." Such symptoms can arise as a result of induced laryngeal obstruction (ILO) or alterations in the mechanics of normal breathing called breathing pattern disorders. Whilst these two types of breathing abnormalities might be related, studies tend to focus on only one of them and do not consider their relationship. Evidence for these problems amongst childhood asthmatics is largely anecdotal. They seem rare in early childhood. Both types are more frequently recognized in the second decade of life and girls are affected more often. These observations tantalizingly parallel epidemiological studies characterizing the increasing prevalence and severity of asthma that also occurs amongst females after puberty. Exercise ILO is more common amongst adolescents and young adults. It should be properly delineated as it might be causally related to specific treatable factors. More severe ILO occurring at rest and breathing pattern disorders are more likely to be occurring within a psychological paradigm. Dysfunctional breathing is associated with asthma morbidity through a number of potential mechanisms. These include anxiety induced breathing pattern disorders and the enhanced perception of subsequent symptoms, cooling and drying of the airways from hyperventilation induced hyperresponsiveness and a direct effect of emotional stimuli on airways constriction via cholinergic pathways. Hyperventilation is the most common breathing pattern disorder amongst adults. Although not validated for use in asthma, the Nijmegen questionnaire has been used to characterize this problem. Studies show higher scores amongst women, those with poorly controlled asthma and those with psychiatric problems. Evidence that treatment with breathing retraining techniques is effective in a primary care population including all types of asthmatics suggests the problem might be more ubiquitous than just these high-risk groups. Future challenges include the need for studies characterizing all types of dysfunctional breathing in pediatric and adult patient cohorts and clearly defined, age appropriate, interventional studies. Clinicians caring for asthmatics in all age groups need to be aware of these co-morbidities and routinely ask about symptoms that suggest these problems.

Risk factors of asthma exacerbation based on asthma severity: a nationwide population-based observational study in South Korea

OBJECTIVES

Asthma exacerbation, associated with many risks factors, can reflect management failure. However, little is known about how risk factors are associated with exacerbation, according to asthma severity. We aimed to investigate differences in risk factors in patients with different asthma severity and evaluate whether risk factors differed between frequent exacerbators and patients with single exacerbation.

DESIGN

Nationwide population-based observational study.

SETTING

Korean National Sample Cohort database.

PARTICIPANTS

We included 22 130 adults with asthma diagnoses more than twice (ICD-10 (International Classification of Diseases, Tenth revision) codes J45 and J46) and one prescription for asthma medication from 2010 to 2011.

OUTCOME MEASURES

Asthma exacerbation was defined as having a corticosteroid (CS) burst characterised by a prescription of high-dose oral CS for ≥3 days or one systemic CS injection, hospitalisation or emergency department visit.

RESULTS

Among severities, history of CS bursts was significantly associated with exacerbation. In mild and moderate asthma, exacerbation was significantly associated with age ≥45 years, being female, gastro-oesophageal reflux disease and chronic rhinitis. High medication possession ratio (MPR≥50%), compared with low MPR (<20%) showed adjusted ORs of 0.828 (95% CI 0.707 to 0.971) and 0.362 (0.185 to 0.708) in moderate and severe asthma, respectively. In severe asthma, compared with mild asthma, only allergic rhinitis and history of hospitalisation were strongly associated with exacerbation. When comparing frequent exacerbators to patients with single exacerbation, age ≥45 years, atopic dermatitis, anxiety and history of CS burst were significant risk factors in mild and moderate asthma, whereas no risk factors were significant in severe asthma.

CONCLUSIONS

Different associations between risk factors and asthma exacerbations based on asthma severity suggest that patients with mild asthma require greater attention to their age and comorbidities, whereas those with severe asthma require greater attention to hospitalisation history and drug adherence.

Factors associated with depressive symptoms in uncontrolled asthmatics

RATIONALE

Recent epidemiological data indicate that approximately 6.7% of US adults suffer from depression in any given year. The purpose of the study is to identify factors associated with depressive symptoms in a large diverse group of patients with poorly controlled asthma. The factors include quality of life (QOL), lung function, asthma knowledge, attitudes, self-efficacy, symptoms and control of disease.

METHODS

Baseline characteristics of a cohort of 599 subjects with asthma recruited from twenty Asthma Clinical Research Centers across the United States were examined. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to stratify subjects into those with depressive symptoms (CES-D score ≥ 16) and those without depressive symptoms (CES-D < 16). Bivariate statistics were used to compare the two groups; additionally, logistic regression was used to determine factors that have the greatest association with depressive symptoms.

RESULTS

Subjects with depressive symptoms had significantly lower QOL scores and less knowledge about their disease than subjects with no depression; however, lung function (FEV1%) and asthma control were not significantly associated with depressive symptoms in the logistic regression analysis. Subjects who were non-white had lower household income, high school diploma or less, and those who were unemployed or disabled had significantly higher scores for depressive symptoms.

CONCLUSION

Subjects with depressive symptoms have significantly less knowledge of their disease and poorer QOL compared to those without depressive symptoms. Evaluating depressive symptoms in subjects with asthma will provide a more complete picture of their overall condition. The role of asthma education on depressive symptoms in this population needs to be further investigated. The effect of QOL on treating depression in asthma patients also needs to be studied.

Role of Adult Asthma Education in Improving Asthma Control and Reducing Emergency Room Utilization and Hospital Admissions in an Inner City Hospital

Objective. Asthma education programs have been shown to decrease healthcare utilization and improve disease control and management. The purpose of our study was to evaluate the impact of an outpatient adult asthma education program in an inner city hospital caring for patients with low socioeconomic and educational status. Methods. An asthma education program was implemented in September 2014. Patients who received education from September 2014 to July 2015 were evaluated. Outcomes were compared for the same group of patients before and after education. Primary outcomes were emergency room (ER) visits and hospital admissions. Secondary outcomes were change in Asthma Control Test (ACT) score and number of pulmonary clinic visits. Results. Asthma education significantly decreased number of patients requiring ER visits and hospital admissions (p = 0.0005 and p = 0.0015, resp.). Asthma control as per ACT score ≥ 20 improved with education (p = 0.0001) with an increase in clinic visits (p = 0.0185). Conclusions. Our study suggests that implementation of a structured asthma education program in an inner city community hospital has a positive impact on reduction of ER visits and hospital admissions with improvement in asthma control. Institutional Review Board Clinical Study registration number is 01081507.

A randomised controlled feasibility trial of Group Cognitive Behavioural Therapy for people with severe asthma

OBJECTIVES

Evidence for the efficacy of Cognitive Behavioural Therapy (CBT) in asthma is developing but it is not known if this translates to benefits in severe asthma or if a group approach is acceptable to this patient group. This study aimed to assess the feasibility and acceptability of Group-CBT in severe asthma.

METHOD

This was a two-centre, randomised controlled parallel group feasibility study. Eligible participants (patients with severe asthma and a clinically significant diagnosis of anxiety and/or depression - Hospital Anxiety and Depression Scale (HAD) score greater than 8 for the anxiety or depression sub-scale) received Group-CBT in weekly sessions for eight consecutive weeks and usual care or usual care only. Follow-up was for 16 weeks and end points were: Asthma Quality of Life Questionnaire, Asthma Control Questionnaire, HAD, Dyspnoea-12, EuroQual-5D and EuroQuol-VAS.

RESULTS

51 patients were randomised: 36% (51 out of 140) consent rate and attrition at week 16 was 12. Screening logs indicated that study take-up was influenced by patients living long distances from the treatment centre and inability to commit to the weekly demands of the programme. Drop-out was higher in Group-CBT compared due to inability to commit to the weekly programme because of poor health. Participants who contributed to focus group discussions reported that Group-CBT contributed to a better understanding of their illness and related approaches to anxiety management and acceptance of their asthma condition. Although weekly face-to-face sessions were challenging, this was the preferred method of delivery for these participants.

CONCLUSIONS

This feasibility study shows that Group-CBT warrants further investigation as a potentially promising treatment option for patients with severe asthma. It has been possible but not easy to recruit and retain the sample. Options for a less demanding intervention schedule, such as less frequent face-to-face visits and the use of web-based interventions, require careful consideration.

Cognitive behavioural therapy (CBT) for adults and adolescents with asthma

BACKGROUND

People with asthma have a higher prevalence of anxiety and depression than the general population. This is associated with poorer asthma control, medication adherence, and health outcomes. Cognitive behavioural therapy (CBT) may be a way to improve the quality of life of people with asthma by addressing associated psychological issues, which may lead to a lower risk of exacerbations and better asthma control.

OBJECTIVES

To assess the efficacy of CBT for asthma compared with usual care.

SEARCH METHODS

We searched the Cochrane Airways Group Specialised Register, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP). We also searched reference lists of all primary studies and review articles and contacted authors for unpublished data. The most recent searches were conducted in August 2016.

SELECTION CRITERIA

We included parallel randomised controlled trials (RCTs) comparing any cognitive behavioural intervention to usual care or no intervention. We included studies of adults or adolescents with asthma, with or without comorbid anxiety or depression. We included studies reported as full text, those published as abstract only, and unpublished data.

DATA COLLECTION AND ANALYSIS

Two or more review authors independently screened the search results, extracted data, and assessed included studies for risk of bias. We analysed dichotomous data as odds ratios (ORs) and continuous data as mean differences (MDs) or standardised mean differences (SMD) where scales varied across studies, all using a random-effects model. The primary outcomes were asthma-related quality of life and exacerbations requiring at least a course of oral steroids. We rated all outcomes using GRADE and presented our confidence in the results in a 'Summary of findings' table.

MAIN RESULTS

We included nine RCTs involving 407 adults with asthma in this review; no studies included adolescents under 18. Study size ranged from 10 to 94 (median 40), and mean age ranged from 39 to 53. Study populations generally had persistent asthma, but severity and diagnostic measures varied. Three studies recruited participants with psychological symptomatology, although with different criteria. Interventions ranged from 4 to 15 sessions, and primary measurements were taken at a mean of 3 months (range 1.2 to 12 months).Participants given CBT had improved scores on the Asthma Quality of Life Questionnaire (AQLQ) (MD 0.55, 95% confidence interval (CI) 0.17 to 0.93; participants = 214; studies = 6; I2 = 53%) and on measures of asthma control (SMD -0.98, 95% CI -1.76 to -0.20; participants = 95; studies = 3; I2 = 68%) compared to people getting usual care. The AQLQ effect appeared to be sustained up to a year after treatment, but due to its low quality this evidence must be interpreted with caution. As asthma exacerbations requiring at least a course of oral steroids were not consistently reported, we could not perform a meta-analysis.Anxiety scores were difficult to pool but showed a benefit of CBT compared with usual care (SMD -0.38, 95% CI -0.73 to -0.03), although this depended on the analysis used. The confidence intervals for the effect on depression scales included no difference between CBT and usual care when measured as change from baseline (SMD -0.33, 95% CI -0.70 to 0.05) or endpoint scores (SMD -0.41, 95% CI -0.87 to 0.05); the same was true for medication adherence (MD -1.40, 95% CI -2.94 to 0.14; participants = 23; studies = 1; I2 = 0%).Subgroup analyses conducted on the AQLQ outcome did not suggest a clear difference between individual and group CBT, baseline psychological status, or CBT model. The small number of studies and the variation between their designs, populations, and other intervention characteristics limited the conclusions that could be drawn about these possibly moderating factors.The inability to blind participants and investigators to group allocation introduced significant potential bias, and overall we had low confidence in the evidence.

AUTHORS' CONCLUSIONS

For adults with persistent asthma, CBT may improve quality of life, asthma control, and anxiety levels compared with usual care. Risks of bias, imprecision of effects, and inconsistency between results reduced our confidence in the results to low, and evidence was lacking regarding the effect of CBT on asthma exacerbations, unscheduled contacts, depression, and medication adherence. There was much variation between studies in how CBT was delivered and what constituted usual care, meaning the most optimal method of CBT delivery, format, and target population requires further investigation. There is currently no evidence for the use of CBT in adolescents with asthma.

A multidisciplinary team case management approach reduces the burden of frequent asthma admissions

Up to 10% of asthmatics have “difficult asthma”; however, they account for 80% of asthma-related expenditure and run the highest risk of acute severe exacerbations. An estimated 75% of admissions for asthma are avoidable. Guidelines advise that these patients be managed by an experienced specialist multidisciplinary team (MDT). We aimed to assess the impact of a case management strategy delivered via specialist MDTs on acute healthcare utilisation of patients with frequent asthma admissions.

An MDT (consultant, specialist nurse, physiotherapist and psychologist) case management strategy was introduced in 2010 at University Hospital Southampton Foundation Trust (Southampton, UK) to support patients with frequent asthma admissions during admission and then in clinic. To assess efficacy, we systematically searched the hospital database for patients acutely admitted for asthma on two or more occasions in 2010, 2011 and 2012. Data were collected retrospectively covering patient demographics, admission details, asthma severity and comorbidity.

From 2010 to 2012, 84 patients were admitted on two or more occasions per year (80% female, mean body mass index 31 kg·m⁻² and 55% psychological comorbidity). After introducing an MDT approach repeat asthma admissions fell by 33% from 127 in 2010 to 84 in 2012 (p=0.0004). In addition, bed days fell by 52% from 895 in 2010 to 430 in 2010 (p=0.015).

An MDT case management approach significantly reduces hospitalisation in difficult asthma patients with prior frequent admission.

Comparing cognitive-behavioural psychotherapy and psychoeducation for non-specific symptoms associated with indoor air: a randomised control trial protocol

INTRODUCTION

Indoor air-related conditions share similarities with other conditions that are characterised by medically unexplained symptoms (MUS)-a combination of non-specific symptoms that cannot be fully explained by structural bodily pathology. In cases of indoor air-related conditions, these symptoms are not fully explained by either medical conditions or the immunological-toxicological effects of environmental factors. The condition may be disabling, including a non-adaptive health behaviour. In this multifaceted phenomenon, psychosocial factors influence the experienced symptoms. Currently, there is no evidence of clinical management of symptoms, which are associated with the indoor environment and cannot be resolved by removing the triggering environmental factors. The aim of this study is to compare the effect of treatment-as-usual (TAU) and two psychosocial interventions on the quality of life, and the work ability of employees with non-specific indoor air-related symptomatology.

METHODS AND ANALYSES

The aim of this ongoing randomised controlled trial is to recruit 60 participants, in collaboration with 5 occupational health service units. The main inclusion criterion is the presence of indoor air-related recurrent symptoms in ≥2 organ systems, which have no pathophysiological explanation. After baseline clinical investigations, participants are randomised into interventions, which all include TAU: cognitive-behavioural psychotherapy, psychoeducation and TAU (control condition). Health-related quality of life, measured using the 15D-scale, is the primary outcome. Secondary outcomes include somatic and psychiatric symptoms, occupational factors, and related underlying mechanisms (ie, cognitive functioning). Questionnaires are completed at baseline, at 3, 6 and 12-month follow-ups. Data collection will continue until 2017. The study will provide new information on the individual factors related to indoor air-associated symptoms, and on ways in which to support work ability.

ETHICS AND DISSEMINATION

The Coordinating Ethics Committee of the Hospital District of Helsinki and Uusimaa, Finland, has granted approval for the study. The results will be published in peer-reviewed journals.

Co-morbid psychological dysfunction is associated with a higher risk of asthma exacerbations: a systematic review and meta-analysis

BACKGROUND

The longitudinal associations between psychological dysfunction (PD) and asthma exacerbations (AE) have not been adequately addressed. This study aimed to systematically assess the influence of PD on AE, and to determine whether different PD affects AE differentially.

METHODS

Electronic databases (PubMed, Cochrane library, Web of Science, Embase, and Ovid) were searched for prospective cohort studies on the influence of PD on AE in individuals with asthma. Relative risk (RR) and adjusted RR (RRadj) were pooled across studies. Subgroup analyses assessed the effects of different types of PD and the time-dependent response to the duration of PD exposure.

RESULTS

Ten articles that involved 31,432 adults with asthma with follow-up of 6.0-86.4 months were included. PD significantly increased the risk of AE [RRadj =1.06, 95% confidence interval (95%CI): 1.04-1.09, P<0.001], presenting as hospitalizations (RRadj =1.22, 95% CI: 1.12-1.34, P<0.001), unscheduled doctor visits (RR =4.26, 95% CI: 2.52-7.19), and emergency department (ED) visits (RRadj =1.06, 95% CI: 1.01-1.10, P=0.009) because of asthma. Depression significantly increased the risk of AE (RRadj =1.07, 95% CI: 1.04-1.11, P<0.001), presenting as hospitalizations (RRadj =1.26, 95% CI: 1.07-1.49, P=0.007) and ED visits (RRadj =1.06, 95% CI: 1.02-1.11, P=0.007) because of asthma. Anxiety was only associated with an increased risk of AE in pregnant women (RR =1.05, 95% CI: 1.01-1.08), possibly due to the small amount of data available on anxiety. The influence of PD on AE was only significant when the PD exposure time exceeded one year.

CONCLUSIONS

Co-morbid PD adversely affects AE, and there are differential effects of depression and anxiety. Asthmatic subjects with PD may benefit from more attention when establishing a treatment regimen in clinical practice.

How can adherence to asthma medication be enhanced? Triangulation of key asthma stakeholders' perspectives

BACKGROUND AND OBJECTIVES

Adherence to daily asthma controller medication has been shown to be the most effective component of asthma self-management; however, patient's adherence to asthma medication remains poor. This study aimed to understand how patients' long-term asthma controller medication adherence may be improved and facilitated by comparing key asthma stakeholders' perspectives.

METHOD

Six focus group interviews including 38 asthma stakeholders (n = 13 patients, n = 13 pulmonologist physicians, and n = 12 allied healthcare professionals) were conducted. Interviews were qualitatively analysed.

RESULTS

Although similar themes were brought up across different asthma stakeholders, the way in which they were framed differed across stakeholders. The most salient discussion revolved around the content and the moment in which asthma education should be approached to facilitate patients' adherence to asthma medication.

CONCLUSION

Asthma medication adherence is a complex process and successful interventions aimed at its improvement would benefit from: (a) making an effort to understand patients' experiences and negotiate the treatment regimen, rather than imposing recommendations; (b) considering treatment as a shared responsibility involving the patient, the healthcare professional(s), and the patients' social networks; and,

Psychological interventions for distress in adults undergoing haematopoietic stem cell transplantation: a systematic review with meta-analysis

OBJECTIVES

To investigate the characteristics, methodology, quality, and efficacy of psychological interventions for distress in adult patients undergoing haematopoietic stem cell transplantation (HSCT).

METHODS

A systematic review of relevant studies was conducted using six databases with supplementary hand searching. Included studies employed an experimental or quasi-experimental design, interventions included at least one psychological component, and outcomes involved psychological distress in affective terms. Data were abstracted, and study quality was assessed using Cochrane Foundation criteria amended to include confounder and common factors control. Data were examined and synthesised using a narrative approach and meta-analysis.

RESULTS

Eleven articles for nine interventions met the inclusion criteria out of 11,741 abstracts. The studies varied in quality, general, intervention, and methodological characteristics while findings were mixed. Interventions tended to show better efficacy when incorporating a major psychological component involving cognitive behavioural or emotional processing methods with substantial interventionist input. However, this was also associated with methodological limitations and threats to internal validity such as poor confounder and common factors control. A meta-analysis yielded a small but significant pooled effect size estimate in favour of interventions with inconsequential heterogeneity. Risk of bias remained a concern.

CONCLUSIONS

Psychological interventions may provide some benefit in alleviating distress in HSCT but conclusions remain tentative in light of methodological limitations and risk of bias. Further research is needed to evidence the individual contribution of intervention components and mechanism of change together with improving intervention efficiency and methodological quality.

Challenges in the Management of Asthma in the Elderly

Recent literature has emphasized the clinical and socio-epidemiological significance of asthma in the elderly. However, why the disease burden remains high in this group is unclear. Elderly subjects usually have multiple chronic illnesses, and the role played by comorbidities in the context of asthma has been underappreciated. This review aims to summarize the literature associations between comorbidities and asthma in elderly patients. In addition, we discuss patient management issues.

Interventions for managing asthma in pregnancy

BACKGROUND

Asthma is the most common respiratory disorder complicating pregnancy, and is associated with a range of adverse maternal and perinatal outcomes. There is strong evidence however, that the adequate control of asthma can improve health outcomes for mothers and their babies. Despite known risks of poorly controlled asthma during pregnancy, a large proportion of women have sub-optimal asthma control, due to concerns surrounding risks of pharmacological agents, and uncertainties regarding the effectiveness and safety of different management strategies.

OBJECTIVES

To assess the effects of interventions (pharmacologic and non-pharmacologic) for managing women's asthma in pregnancy on maternal and fetal/infant outcomes.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (2 June 2014) and the Cochrane Airways Group's Trials Register (4 June 2014).

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials comparing any intervention used to manage asthma in pregnancy, with placebo, no intervention, or an alternative intervention. We included pharmacological and non-pharmacological interventions (including combined interventions). Cluster-randomised trials were eligible for inclusion (but none were identified). Cross-over trials were not eligible for inclusion.We included multi-armed trials along with two-armed trials. We also included studies published as abstracts only.

DATA COLLECTION AND ANALYSIS

At least two review authors independently assessed trial eligibility and quality and extracted data. Data were checked for accuracy.

MAIN RESULTS

We included eight trials in this review, involving 1181 women and their babies. Overall we judged two trials to be at low risk of bias, two to be of unclear risk of bias, and four to be at moderate risk of bias.Five trials assessed pharmacological agents, including inhaled corticosteroids (beclomethasone or budesonide), inhaled magnesium sulphate, intravenous theophylline, and inhaled beclomethasone verus oral theophylline. Three trials assessed non-pharmacological interventions, including a fractional exhaled nitric oxide (FENO)-based algorithm versus a clinical guideline-based algorithm to adjust inhaled corticosteroid therapy, a pharmacist-led multi-disciplinary approach to management versus standard care, and progressive muscle relaxation (PMR) versus sham training.The eight included trials were assessed under seven separate comparisons. Pharmacological interventionsPrimary outcomes: one trial suggested that inhaled magnesium sulphate in addition to usual treatment could reduce exacerbation frequency in acute asthma (mean difference (MD) -2.80; 95% confidence interval (CI) -3.21 to -2.39; 60 women). One trial assessing the addition of intravenous theophylline to standard care in acute asthma did not report on exacerbations (65 women). No clear difference was shown in the risk of exacerbations with the use of inhaled beclomethasone in addition to usual treatment for maintenance therapy in one trial (risk ratio (RR) 0.36; 95% CI 0.13 to 1.05; 60 women); a second trial also showed no difference, however data were not clearly reported to allow inclusion in a meta-analysis. No difference was shown when inhaled beclomethasone was compared with oral theophylline for maintenance therapy (RR 0.88; 95% CI 0.59 to 1.33; one trial, 385 women). None of these trials reported on neonatal intensive care admissions.

SECONDARY OUTCOMES

inhaled magnesium sulphate in acute asthma was shown to improve lung function measures (one trial, 60 women); intravenous theophylline in acute asthma was not associated with benefits (one trial, 65 women). No clear differences were seen with the addition of inhaled corticosteroids to routine treatment in three trials (374 women). While inhaled beclomethasone, compared with oral theophylline, significantly reduced treatment discontinuation due to adverse effects in one trial (384 women), no other differences were observed, except for higher treatment adherence with theophylline. Four of the five trials did not report on adverse effects. Non-pharmacological interventionsPrimary outcomes: in one trial, the use of a FENO-based algorithm was shown to significantly reduce asthma exacerbations (RR 0.61; 95% CI 0.41 to 0.90; 220 women); and a trend towards fewer neonatal hospitalisations was observed (RR 0.46; 95% CI 0.21 to 1.02; 214 infants). No exacerbations occurred in one trial assessing pharmacist-led management; this approach did not reduce neonatal intensive care admissions (RR 1.50; 95% CI 0.27 to 8.32; 58 infants). One trial (64 women) assessing PMR did not report on exacerbations or neonatal intensive care admissions.

SECONDARY OUTCOMES

the use of a FENO-based algorithm to adjust therapy led to some improvements in quality of life scores, as well as more frequent use of inhaled corticosteroids and long-acting β-agonists, and less frequent use of short-acting β-agonists (one trial, 220 women). The FENO-based algorithm was associated with fewer infants with recurrent episodes of bronchiolitis in their first year of life, and a trend towards fewer episodes of croup for infants. Pharmacist-led management improved asthma control scores at six months (one trial, 60 women); PMR improved lung function and quality of life measures (one trial, 64 women). No other differences between comparisons were observed.

AUTHORS' CONCLUSIONS

Based on eight included trials, of moderate quality overall, no firm conclusions about optimal interventions for managing asthma in pregnancy can be made. Five trials assessing pharmacological interventions did not provide clear evidence of benefits or harms to support or refute current practice. While inhaled magnesium sulphate for acute asthma was shown to reduce exacerbations, this was in one small trial of unclear quality, and thus this finding should be interpreted with caution. Three trials assessing non-pharmacological interventions provided some support for the use of such strategies, however were not powered to detect differences in important maternal and infant outcomes. While a FENO-based algorithm reduced exacerbations, the effects on perinatal outcomes were less certain, and thus widespread implementation is not yet appropriate. Similarly, though positive effects on asthma control were shown with PMR and pharmacist-led management, the evidence to date is insufficient to draw definitive conclusions.In view of the limited evidence base, further randomised trials are required to determine the most effective and safe interventions for asthma in pregnancy. Future trials must be sufficiently powered, and well-designed, to allow differences in important outcomes for mothers and babies to be detected. The impact on health services requires evaluation. Any further trials assessing pharmacological interventions should assess novel agents or those used in current practice. Encouragingly, at least five trials have been identified as planned or underway.

Psychological interventions for individuals with cystic fibrosis and their families

BACKGROUND

With increasing survival estimates for individuals with cystic fibrosis, long-term management has become an important focus. Psychological interventions are largely concerned with adherence to treatment, emotional and social adaptation and health-related quality of life. We are unaware of any relevant systematic reviews.

OBJECTIVES

To determine whether psychological interventions for people with cystic fibrosis provide significant psychosocial and physical benefits in addition to standard medical care.

SEARCH METHODS

Studies were identified from two Cochrane trials registers (Cystic Fibrosis and Genetic Disorders Group; Depression, Anxiety and Neurosis Group), Ovid MEDLINE and PsychINFO; unpublished trials were located through professional networks and Listserves. Most recent search of the Cystic Fibrosis and Genetic Disorders Group's register: 19 December 2013.Most recent search of the Depression, Anxiety and Neurosis Group's register: 12 November 2013.

SELECTION CRITERIA

Randomised controlled studies of a broad range of psychological interventions evaluating subjective and objective health outcomes, such as quality of life or pulmonary function, in individuals of all ages with cystic fibrosis and their immediate family. We were interested in psychological interventions, including psychological methods within the scope of psychotherapeutic or psychosomatic mechanism of action (e.g. cognitive behavioural, cognitive, family systems or systemic, psycho-dynamic, or other, e.g. supportive, relaxation, or biofeedback), which were aimed at improving psychological and psychosocial outcomes (e.g. quality of life, levels of stress or distress, psychopathology, etc.), adaptation to disease management and physiological outcomes.

DATA COLLECTION AND ANALYSIS

Three authors were involved in selecting the eligible studies and two of these authors assessed their risk of bias.

MAIN RESULTS

The review includes 16 studies (eight new studies included in this update) representing data from 556 participants. Studies are diverse in their design and their methods. They cover interventions with generic approaches, as well as interventions developed specifically to target disease-specific symptoms and problems in people with cystic fibrosis. These include cognitive behavioural interventions to improve adherence to nutrition or psychosocial adjustment, cognitive interventions to improve adherence or those associated with decision making in lung transplantation, a community-based support intervention and other interventions, such as self-hypnosis, respiratory muscle biofeedback, music therapy, dance and movement therapy, and a tele-medicine intervention to support patients awaiting transplantation.A substantial proportion of outcomes relate to adherence, changes in physical status or other specific treatment concerns during the chronic phase of the disease.There is some evidence that behavioural interventions targeting nutrition and growth in children (4 to 12 years) with cystic fibrosis are effective in the short term. Evidence was found that providing a structured decision-making tool for patients considering lung transplantation improves patients' knowledge of and expectations about the transplant, and reduces decisional conflict in the short term. One study about training in biofeedback-assisted breathing demonstrated some evidence that it improved some lung function measurements. Currently there is insufficient evidence for interventions aimed at other aspects of the disease process.

AUTHORS' CONCLUSIONS

Currently, insufficient evidence exists on psychological interventions or approaches to support people with cystic fibrosis and their caregivers, although some of the studies were promising. Due to the heterogeneity between studies, more of each type of intervention are needed to support preliminary evidence. Multicentre studies, with consequent funding implications, are needed to increase the sample size of these studies and enhance the statistical power and precision to detect important findings. In addition, multicentre studies could improve the generalisation of results by minimizing centre or therapist effects. Psychological interventions should be targeted to illness-specific symptoms or behaviours to demonstrate efficacy.

Written emotional disclosure for asthma

BACKGROUND

Psychological stress has been widely implicated in asthma exacerbation. Evidence suggests that written emotional disclosure, an intervention that involves writing about traumatic or stressful experiences, helps to reduce stress and promote physical and psychological well-being. Written emotional disclosure may have a role in the management of asthma.

OBJECTIVES

This review aims to determine the effectiveness of written emotional disclosure for people with asthma, specifically, to assess:1. overall efficacy of emotional disclosure compared with emotionally neutral writing on self reported quality of life in people with asthma;2. overall efficacy of emotional disclosure compared with emotionally neutral writing on objective measures of health outcome in people with asthma; and3. comparative efficacy of different types of emotional disclosure for people with asthma.

SEARCH METHODS

Trials were identified from the Cochrane Airways Group Specialised Register of trials, CENTRAL, MEDLINE, EMBASE, CINAHL, AMED and PsycINFO. The latest search was conducted in January 2014.

SELECTION CRITERIA

Randomised controlled trials published in any language comparing written emotional disclosure intervention versus a control writing (emotionally neutral) intervention in participants with asthma were included in the review.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies against predetermined inclusion criteria and extracted the data. Corresponding authors were contacted when necessary to provide additional information.

MAIN RESULTS

Four studies, involving a total of 414 participants, met the inclusion criteria. Three studies were conducted in adult participants and one in adolescents. The average age of participants ranged from 14 to 43 years. The trials lasted between two months and 12 months. The interventions were based on Pennebaker's method. The risk of bias across most domains of the studies was generally considered to be low, however three of four studies were considered at high risk of bias due to lack of assessor blinding and one study was at high risk of bias for selective reporting. The interpretation of these studies was limited by diverse outcome measurements, measurement tools, control group techniques, and number and/or times of follow-up. A pooled result from the four studies, including a total of 146 intervention and 135 control participants, indicated uncertain effect in forced expiratory volume in one second (FEV1) % predicted between the disclosure group and the control group (mean difference (MD) 3.43%, 95% confidence interval (CI) -0.61% to 7.47%; very low-quality evidence) at ≤ three months' follow-up. Similarly, evidence from two studies indicated that written emotional disclosure found uncertain effect on forced vital capacity (FVC) (standardised mean difference (SMD) -0.02, 95% CI -0.30 to 0.26; low-quality evidence) and asthma symptoms (SMD -0.22, 95% CI -0.52 to 0.09; low-quality evidence) but may result in improved asthma control at ≤ three months' follow-up (SMD 0.29, 95% CI 0.01 to 0.58; low-quality evidence). We were unable to pool the data for other outcomes. Results from individual trials did not reveal a significant benefit of written emotional disclosure for quality of life, medication use, healthcare utilisation or psychological well-being. Evidence from one trial suggests a significant reduction in beta agonist use (MD -1.62, 95% CI -2.62 to -0.62; low-quality evidence) at ≤ three months' follow-up in the disclosure group compared with controls. The review did not address any adverse effects of emotional writing.

AUTHORS' CONCLUSIONS

Evidence was insufficient to show whether written emotional disclosure compared with writing about non-emotional topics had an effect on the outcomes included in this review. Evidence is insufficient to allow any conclusions as to the role of disclosure in quality of life, psychological well-being, medication use and healthcare utilisation. The evidence presented in this review is generally of low quality. Better designed studies with standardised reporting of outcome measurement instruments are required to determine the effectiveness of written emotional disclosure in the management of asthma.

Coexisting chronic conditions associated with mortality and morbidity in adult patients with asthma

OBJECTIVE

Many asthma patients suffer from chronic conditions other than asthma. We investigated the specific contribution of common comorbidities on mortality and morbidity in adult asthma.

METHODS

In an observational study of adults with incident asthma identified between 1999 and 2003 using National Veterans Affairs and Centers for Medicare and Medicaid Services encounter databases (n = 25 975, follow-up 3.0 ± 1.7 years), association between 13 most prevalent comorbidities (hypertension, ischemic heart disease (IHD), osteoarthritis, rheumatoid arthritis, diabetes, mental disorders, substance/drug abuse, enlarged prostate, depression, cancer, alcoholism, HIV and heart failure) and four conditions previously associated with asthma (sleep apnea, gastroesophageal reflux disease (GERD), rhinitis and sinusitis) and mortality, hospitalizations and asthma exacerbations were assessed using multivariate regression analyses adjusted for other clinically important covariates.

RESULTS

HIV followed by alcoholism and mental disorders among 18-45-years old, and heart failure, diabetes, IHD and cancer among those ≥ 65 years old were associated with an increased risk of all-cause mortality. Many conditions were associated with increased risk for all-cause hospitalizations, but the increased risk was consistent across all ages for mental disorders. For asthma exacerbations, mental disorder followed by substance abuse and IHD were associated with increased risk among those 18-45 years old, and chronic sinusitis, mental disorder and IHD among those ≥ 65-years old. GERD was associated with decreased risk for asthma exacerbation in all ages.

CONCLUSIONS

Many comorbidities are associated with poor outcome in adult asthmatics and their effect differs by age. Mental disorders are associated with increased risk of mortality and morbidity across ages.

A systematic review of psychological interventions for adult and pediatric patients with vocal cord dysfunction

BACKGROUND

Vocal cord dysfunction (VCD) or paradoxical vocal-fold motion (PVFM) is a functional disorder of the vocal cords that requires multidisciplinary treatment. Besides relaxation techniques, the use of psychological interventions can help treat the underlying psychological co-morbidities. There is currently no literature that examines the effectiveness of psychological interventions for VCD/PVFM.

OBJECTIVES

To review the evidence for psychological interventions used for the treatment of patients with VCD/PVFM.

DATA SOURCES

We searched electronic databases for English medical literature using Pubmed (Medline), PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Registry of Controlled Trials, and Clinicaltrials.gov. The date range for our search is from June 1964 to June 2014.

STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS

We included studies that reported the use of psychological interventions in both adults and children diagnosed with VCD/PVFM. We included randomized controlled trials, case-control studies, retrospective chart reviews, prospective case series, and individual case reports.

RESULTS

Most reported studies are small case series or individual case reports that have described the use of interventions such as psychotherapy, behavioral therapy, use of anti-anxiety and anti-depressant medications, and hypnotherapy in conjunction with breathing exercises taught by speech therapists for symptomatic relief. Among the various psychological interventions that have been reported, there is no data regarding effectiveness and/or superiority of one approach over another in either adult or pediatric patients.

CONCLUSIONS

Psychological interventions have a role to play in the management of adult and pediatric patients with VCD/PVFM. Future prospective studies using uniform approaches for treatment of associated psychopathology may help address this question.

Processes of change in an asthma self-care intervention

In this article, we present a qualitative exploration of the psychological and communication processes that occur within an intervention to improve self-care for people with asthma. In the context of a primary-care-based trial of the intervention, we collected data at three time points for 21 patients, comprising 2 audiotaped consultations (nurse and patient together) and individual semistructured interviews 3 months after the second consultation. Using framework analysis, we identified both psychological processes (illness understanding, affective response to asthma, and reasoned motivation) and patient-provider interactions (active patient involvement and individual tailoring). We use these findings to extend and refine the pre-existing theoretical model of behavior change underpinning the intervention, in particular with relation to patient-provider interaction processes. We conclude that it is important for developers and providers of asthma self-care interventions to attend to the style of delivery as well as the behavior change techniques involved.

An integrative review of systematic reviews related to the management of breathlessness in respiratory illnesses

BACKGROUND

Breathlessness is a debilitating and distressing symptom in a wide variety of diseases and still a difficult symptom to manage. An integrative review of systematic reviews of non-pharmacological and pharmacological interventions for breathlessness in non-malignant disease was undertaken to identify the current state of clinical understanding of the management of breathlessness and highlight promising interventions that merit further investigation.

METHODS

Systematic reviews were identified via electronic databases between July 2007 and September 2009. Reviews were included within the study if they reported research on adult participants using either a measure of breathlessness or some other measure of respiratory symptoms.

RESULTS

In total 219 systematic reviews were identified and 153 included within the final review, of these 59 addressed non-pharmacological interventions and 94 addressed pharmacological interventions. The reviews covered in excess of 2000 trials. The majority of systematic reviews were conducted on interventions for asthma and COPD, and mainly focussed upon a small number of pharmacological interventions such as corticosteroids and bronchodilators, including beta-agonists. In contrast, other conditions involving breathlessness have received little or no attention and studies continue to focus upon pharmacological approaches. Moreover, although there are a number of non-pharmacological studies that have shown some promise, particularly for COPD, their conclusions are limited by a lack of good quality evidence from RCTs, small sample sizes and limited replication.

CONCLUSIONS

More research should focus in the future on the management of breathlessness in respiratory diseases other than asthma and COPD. In addition, pharmacological treatments do not completely manage breathlessness and have an added burden of side effects. It is therefore important to focus more research on promising non-pharmacological interventions.

Psychological factors in asthma

Asthma has long been considered a condition in which psychological factors have a role. As in many illnesses, psychological variables may affect outcome in asthma via their effects on treatment adherence and symptom reporting. Emerging evidence suggests that the relation between asthma and psychological factors may be more complex than that, however. Central cognitive processes may influence not only the interpretation of asthma symptoms but also the manifestation of measurable changes in immune and physiologic markers of asthma. Furthermore, asthma and major depressive disorder share several risk factors and have similar patterns of dysregulation in key biologic systems, including the neuroendocrine stress response, cytokines, and neuropeptides. Despite the evidence that depression is common in people with asthma and exerts a negative impact on outcome, few treatment studies have examined whether improving symptoms of depression do, in fact, result in better control of asthma symptoms or improved quality of life in patients with asthma.

Psychological interventions for adults with asthma

BACKGROUND

Many people have asthma, and for some their symptoms may be triggered by psychological factors. In addition compliance with medical therapy may have a psychological dimension. Therefore, psychological interventions aim to reduce the burden of symptoms and improve management of the disease.

OBJECTIVES

To assess the effectiveness of psychological interventions for adults with asthma.

SEARCH STRATEGY

The Cochrane Airways Group Specialised Register and PsycINFO were searched with pre-defined terms up until August 2005.

SELECTION CRITERIA

Randomised controlled trials published in any language assessing the effects of a psychological intervention compared with a form of control in adult participants were included in the review.

DATA COLLECTION AND ANALYSIS

Two reviewers assessed the relevance of abstracts identified by electronic searching and retrieved agreed studies for further scrutiny. The studies that met the inclusion criteria were assembled and data extracted.

MAIN RESULTS

Fourteen studies, involving 617 particpants, were included in the review, however study quality was poor and sample sizes were frequently small. However, some pooled effects were analysed. The use of 'as needed' medications was reduced in two studies, (47 patients), by relaxation therapy (OR 4.47, CI 1.22 to 16.44). There was no significant difference in FEV1 for relaxation therapy in four studies of 150 patients, (SMD -0.01, CI -0.41 to 0.40). Quality of life, measured using the Asthma Quality of Life Questionnaire in two studies, (48 patients), showed a positive effect following CBT (WMD 0.71, CI 0.23 to 1.19). Peak Expiratory Flow outcome data in two studies, (51 patients), indicated a significant difference in favour of bio-feedback therapy (SMD 0.66, CI 0.09 to 1.23). The remainder of the findings between studies were conflicting. This may have been due to the different types of interventions used and the deficiencies in trial design.

AUTHORS' CONCLUSIONS

This review was unable to draw firm conclusions for the role of psychological interventions in asthma due to the absence of an adequate evidence base. Larger, well-conducted and reported randomised trials are required in this area, in order to determine the effects of these techniques in the treatment of asthma in adults.
