Predictors of success and failure in pulmonary rehabilitation

The purpose of the present study was to identify prognostic features of chronic obstructive pulmonary disease (COPD) associated with success or failure in pulmonary rehabilitation. Patients were stratified according to the Medical Research Council (MRC) dyspnoea score. A total of 74 stable COPD patients (mean±sd age 68±10 yrs), 21 MRC dyspnoea score grade 1/2, 29 grade 3/4 and 24 grade 5, with a mean forced expiratory volume in one second of 1.1±0.6 L, attended for rehabilitation. Assessments consisted of the following: quadriceps torque, 6-minute walking distance (6MWD), Brief Assessment Depression Cards and St Georges Respiratory Questionnaire (SGRQ). Predictors of drop-out and of response (a change in SGRQ of four points or 6MWD of 54 m) were tested using binary logistic regression. In total, 51 patients completed the study. Of these, 39 (77%) showed a clinically significant benefit in either 6MWD or SGRQ. Baseline variables were poor predictors of response in each case. Significant differences were seen between MRC dyspnoea score groups for change in 6MWD and SGRQ Score. Only grade 1/2 and 3/4 patients improved. Depression was a risk factor for subject drop-out compared with nondepressed patients. Baseline state is a poor predictor of response to rehabilitation, although Medical Research Council dyspnoea score grade 5 patients showed smaller magnitudes of improvement than patients with less severe Medical Research Council dyspnoea score grades. Risk of drop-out is significantly greater in depressed compared with nondepressed patients.

WPA guidance on steps, obstacles and mistakes to avoid in the implementation of community mental health care

This paper provides guidance on the steps, obstacles and mistakes to avoid in the implementation of community mental health care. The document is intended to be of practical use and interest to psychiatrists worldwide regarding the development of community mental health care for adults with mental illness. The main recommendations are presented in relation to: the need for coordinated policies, plans and programmes, the requirement to scale up services for whole populations, the importance of promoting community awareness about mental illness to increase levels of help-seeking, the need to establish effective financial and budgetary provisions to directly support services provided in the community. The paper concludes by setting out a series of lessons learned from the accumulated practice of community mental health care to date worldwide, with a particular focus on the social and governmental measures that are required at the national level, the key steps to take in the organization of the local mental health system, lessons learned by professionals and practitioners, and how to most effectively harness the experience of users, families, and other advocates.

Asthma health status measurement in clinical practice: validity of a new short and simple instrument.

Health status (Quality of Life) questionnaires for use in asthma are generally too long or complex for routine use. A new short and simple measure of health status in asthma has been developed for this purpose. There are two versions, one containing 30 items (AQ30) and the other 20 items (AQ20). This study examined their cross-sectional and longitudinal properties and compared them with those of two established measures--the St. Georges Respiratory Questionnaire (SGRQ) and the Asthma Quality of Life Questionnaire (AQLQ). Ninety asthmatic patients (mean age 46 years) participated. Mean post-bronchodilator forced expiratory volume in one second (FEV1) was 73 +/- 25 (SD)% predicted at baseline. Questionnaire data were collected twice, 12 weeks apart. Diary records of peak expiratory flow rate (PEFR) and daily asthma were kept for 14 days. The new questionnaires each took 3 min or less to complete. At baseline they correlated well with the SGRQ and AQLQ and showed the same pattern of correlations with clinical measures of asthma. Change scores for the new questionnaires correlated with those for the established measures. There was no advantage of the AQ30 over the AQ20. The AQ20 provides a simple method for obtaining valid health status estimates of asthmatics in routine clinical practice and has properties similar to more complex research instruments.

Cancer diagnosis in people with severe mental illness: practical and ethical issues

There has been increasing recognition of the high physical morbidity in patients with severe mental illness, but little has been written about cancer in these patients. Therefore, we review the published work on risk of cancer in patients with severe mental illness, treatment challenges, and ethical issues. Severe mental illness is associated with behaviours that predispose an individual to an increased risk of some cancers, including lung and breast cancer, although lower rates of other cancers are reported in this population. Severe mental illness is also associated with disparities in screening for cancer and with higher case-fatality rates. This higher rate is partly due to the specific challenges of treating these patients, including medical comorbidity, drug interactions, lack of capacity, and difficulties in coping with the treatment regimen as a result of psychiatric symptoms. To ensure that patients with severe mental illness receive effective treatment, inequalities in care need to be addressed by all health-care professionals involved, including those from mental health services and the surgical and oncology teams.

Evidence for effective interventions to reduce mental health-related stigma and discrimination in the medium and long term: systematic review

Background Most research on interventions to counter stigma and discrimination has focused on short-term outcomes and has been conducted in high-income settings. Aims To synthesise what is known globally about effective interventions to reduce mental illness-based stigma and discrimination, in relation first to effectiveness in the medium and long term (minimum 4 weeks), and second to interventions in low- and middle-income countries (LMICs). Method We searched six databases from 1980 to 2013 and conducted a multi-language Google search for quantitative studies addressing the research questions. Effect sizes were calculated from eligible studies where possible, and narrative syntheses conducted. Subgroup analysis compared interventions with and without social contact. Results Eighty studies (n = 422 653) were included in the review. For studies with medium or long-term follow-up (72, of which 21 had calculable effect sizes) median standardised mean differences were 0.54 for knowledge and −0.26 for stigmatising attitudes. Those containing social contact (direct or indirect) were not more effective than those without. The 11 LMIC studies were all from middle-income countries. Effect sizes were rarely calculable for behavioural outcomes or in LMIC studies. Conclusions There is modest evidence for the effectiveness of anti-stigma interventions beyond 4 weeks follow-up in terms of increasing knowledge and reducing stigmatising attitudes. Evidence does not support the view that social contact is the more effective type of intervention for improving attitudes in the medium to long term. Methodologically strong research is needed on which to base decisions on investment in stigma-reducing interventions.

Effects of short-term interventions to reduce mental health-related stigma in university or college students: a systematic review

Abstract Although there are many interventions to reduce mental health–related stigma in university or college students, their overall effect is unknown. This article systematically reviews intervention studies and aims to identify the effective approaches. We searched 11 bibliographic databases, Google, Web sites of relevant associations, and reference lists and contacted specialists. A total of 35 studies (N = 4257) of a wide range of interventions met the inclusion criteria. Social contact or video-based social contact interventions seemed to be the most effective in improving attitudes and reducing desire for social distance. Evidence from one study suggests that a lecture that provided treatment information may enhance students’ attitudes toward the use of services. However, methodological weaknesses in many studies were also found. There was a lack of evidence for interventions in medical students, for long-term effects of interventions, or for having a positive impact on actual behaviors. Further research having more rigorous methods is needed to confirm this.

Depression in Primary Care Patients with Coronary Heart Disease: Baseline Findings from the UPBEAT UK Study

Background An association between depression and coronary heart disease is now accepted but there has been little primary care research on this topic. The UPBEAT-UK studies are centred on a cohort of primary patients with coronary heart disease assessed every six months for up to four years. The aim of this research was to determine the prevalence and associations of depression in this cohort at baseline. Method Participants with coronary heart disease were recruited from general practice registers and assessed for cardiac symptoms, depression, quality of life and social problems. Results 803 people participated. 42% had a documented history of myocardial infarction, 54% a diagnosis of ischaemic heart disease or angina. 44% still experienced chest pain. 7% had an ICD-10 defined depressive disorder. Factors independently associated with this diagnosis were problems living alone (OR 5.49, 95% CI 2.11–13.30), problems carrying out usual activities (OR 3.71, 95% CI 1.93–7.14), experiencing chest pain (OR 3.27, 95% CI 1.58–6.76), other pains or discomfort (OR 3.39, 95% CI 1.42–8.10), younger age (OR 0.95 per year 95% CI 0.92–0.98). Conclusion Problems living alone, chest pain and disability are important predictors of depression in this population.

The UPBEAT nurse-delivered personalized care intervention for people with coronary heart disease who report current chest pain and depression: a randomised controlled pilot study.

Background Depression is common in people with coronary heart disease (CHD) and associated with worse outcome. This study explored the acceptability and feasibility of procedures for a trial and for an intervention, including its potential costs, to inform a definitive randomized controlled trial (RCT) of a nurse-led personalised care intervention for primary care CHD patients with current chest pain and probable depression. Methods Multi-centre, outcome assessor-blinded, randomized parallel group study. CHD patients reporting chest pain and scoring 8 or more on the HADS were randomized to personalized care (PC) or treatment as usual (TAU) for 6 months and followed for 1 year. Primary outcome was acceptability and feasibility of procedures; secondary outcomes included mood, chest pain, functional status, well being and psychological process variables. Result 1001 people from 17 General Practice CHD registers in South London consented to be contacted; out of 126 who were potentially eligible, 81 (35% female, mean age = 65 SD11 years) were randomized. PC participants (n = 41) identified wide ranging problems to work on with nurse-case managers. Good acceptability and feasibility was indicated by low attrition (9%), high engagement and minimal nurse time used (mean/SD = 78/19 mins assessment, 125/91 mins telephone follow up). Both groups improved on all outcomes. The largest between group difference was in the proportion no longer reporting chest pain (PC 37% vs TAU 18%; mixed effects model OR 2.21 95% CI 0.69, 7.03). Some evidence was seen that self efficacy (mean scale increase of 2.5 vs 0.9) and illness perceptions (mean scale increase of 7.8 vs 2.5) had improved in PC vs TAU participants at 1 year. PC appeared to be more cost effective up to a QALY threshold of approximately £3,000. Conclusions Trial and intervention procedures appeared to be feasible and acceptable. PC allowed patients to work on unaddressed problems and appears cheaper than TAU. Trial Registration Controlled-Trials.com ISRCTN21615909

A pilot randomised controlled trial of personalised care for depressed patients with symptomatic coronary heart disease in South London general practices: the UPBEAT-UK RCT protocol and recruitment

BackgroundCommunity studies reveal people with coronary heart disease (CHD) are twice as likely to be depressed as the general population and that this co-morbidity negatively affects the course and outcome of both conditions. There is evidence for the efficacy of collaborative care and case management for depression treatment, and whilst NICE guidelines recommend these approaches only where depression has not responded to psychological, pharmacological, or combined treatments, these care approaches may be particularly relevant to the needs of people with CHD and depression in the earlier stages of stepped care in primary care settings.MethodsThis pilot randomised controlled trial will evaluate whether a simple intervention involving a personalised care plan, elements of case management and regular telephone review is a feasible and acceptable intervention that leads to better mental and physical health outcomes for these patients. The comparator group will be usual general practitioner (GP) care.81 participants have been recruited from CHD registers of 15 South London general practices. Eligible participants have probable major depression identified by a score of ≥8 on the Hospital Anxiety and Depression Scale depression subscale (HADS-D) together with symptomatic CHD identified using the Modified Rose Angina Questionnaire.Consenting participants are randomly allocated to usual care or the personalised care intervention which involves a comprehensive assessment of each participant’s physical and mental health needs which are documented in a care plan, followed by regular telephone reviews by the case manager over a 6-month period. At each review, the intervention participant’s mood, function and identified problems are reviewed and the case manager uses evidence based behaviour change techniques to facilitate achievement of goals specified by the patient with the aim of increasing the patient’s self efficacy to solve their problems.Depressive symptoms measured by HADS score will be collected at baseline and 1, 6- and 12 months post randomisation. Other outcomes include CHD symptoms, quality of life, wellbeing and health service utilisation.DiscussionThis practical and patient-focused intervention is potentially an effective and accessible approach to the health and social care needs of people with depression and CHD in primary care.Trial registrationISRCTN21615909.

The UPBEAT depression and coronary heart disease programme: using the UK medical research council framework to design a nurse-led complex intervention for use in primary care

BackgroundDepression is common in coronary heart disease (CHD) and increases the incidence of coronary symptoms and death in CHD patients. Interventions feasible for use in primary care are needed to improve both mood and cardiac outcomes. The UPBEAT-UK programme of research has been funded by the NHS National Institute for Health Research (NIHR) to explore the relationship between CHD and depression and to develop a new intervention for use in primary care.MethodsUsing the Medical Research Council (MRC) guidelines for developing and evaluating complex interventions, we conducted a systematic review and qualitative research to develop a primary care-based nurse-led intervention to improve mood and cardiac outcomes in patients with CHD and depression. Iterative literature review was used to synthesise our empirical work and to identify evidence and theory to inform the intervention.ResultsWe developed a primary care-based nurse-led personalised care intervention which utilises elements of case management to promote self management. Following biopsychosocial assessment, a personalised care plan is devised. Nurses trained in behaviour change techniques facilitate patients to address the problems important to them. Identification and utilisation of existing resources is promoted. Nurse time is conserved through telephone follow up.ConclusionsApplication of the MRC framework for complex interventions has allowed us to develop an evidence based intervention informed by patient and clinician preferences and established theory. The feasibility and acceptability of this intervention is now being tested further in an exploratory trial.
