Remedial therapy after stroke: a randomised controlled trial.

Of 1094 patients with a confirmed stroke admitted to Northwick Park, a district general hospital, 364 (33%) died while in hospital, 215 (20%) were fully recovered when discharged, and 329 (30%) were too frail or too ill from diseases other than stroke to be considered for active rehabilitation. Only 121 (11%) were suitable for intensive treatment. They and 12 patients referred direct to outpatients were allocated at random to one of three different courses of rehabilitation. Intensive was compared with conventional rehabilitation and with a third regimen which included no routine rehabilitation, but under which patients were encouraged to continue with exercises taught while in hospital and were regularly seen at home by a health visitor. Progress at three months and 12 months was measured by an index of activities of daily living. Improvement was greatest in those receiving intensive treatment, intermediate in those receiving conventional treatment, and least in those receiving no routine treatment. Decreasing intensity of treatment was associated with a significant increase in the proportions of patients who deteriorated and in the extent to which they deteriorated. Probably only a few stroke patients, mostly men, are suitable for intensive outpatient rehabilitation, but for those patients the treatment is effective and realistic.     

Evaluation of adjuvant psychological therapy in patients with testicular cancer: randomised controlled trial.

OBJECTIVE: To determine the efficacy of adjuvant psychological therapy in patients with testicular cancer and to compare the characteristics and psychosocial outcomes of men who agreed to participate with those who declined to participate in a randomised trial of psychological intervention. DESIGN: Newly diagnosed patients were asked to participate in a randomised trial of psychological support compared with standard medical care. Participants and non-participants completed self assessment questionnaires at baseline and at 2, 4 and 12 months. SETTING: Testicular Tumour Unit of the Royal Marsden Hospital. SUBJECTS: 73 of 184 (40%) eligible patients agreed to enter the randomised trial (participants) and 81 (44%) declined to participate but agreed to complete further assessments (non-participants). 30 patients wanted no further contact with the researchers. OUTCOME MEASURES: Hospital anxiety and depression scale, psychosocial adjustment to illness scale, Rotterdam symptom checklist, mental adjustment to cancer scale. Only scores on the hospital anxiety and depression scale are reported for evaluating treatment efficacy. RESULTS: 111 of 184 (60%) eligible men declined to participate in the trial. Patients with stage I disease were most likely to refuse to participate. A patient was less likely to participate if he had low volume disease and was receiving no further treatment. Likelihood of participation was associated with stage of disease and with type of primary treatment (P < 0.001 for heterogeneity). Patients with early stage disease (P < 0.001) and fewer physical symptoms (P < 0.001) were less likely to participate. Psychosocial factors associated with participation included anxious preoccupation regarding disease (P = 0.01). There were no differences in outcome between participants and non-participants during follow up. Patients seemed to gain little benefit from adjuvant psychological therapy. At 2 months change from baseline favoured the treated group in the anxiety subscale (mean difference between groups -1.41 (95% confidence interval -2.86 to 0.03)). This was not sustained when adjusted for factors related to the disease. By 12 months change from baseline seemed to favour the control group (mean difference between groups 1.66 (-0.18 to 3.50)). CONCLUSIONS: Patients with testicular cancer seem to have considerable coping abilities. Those who declined to participate in the trial differed from those who participated. Those who agreed to participate may comprise the clinical group who perceive a need for psychological support. No evidence was found to indicate a need for routinely offering adjuvant psychological therapy.     

Cognitive behaviour therapy for adolescents with chronic fatigue syndrome: randomised controlled trial

Objective To evaluate the efficacy of cognitive behaviour therapy for adolescents aged 10-17 years with chronic fatigue syndrome.Design Randomised controlled trial.Setting Department of child psychology.Participants 71 consecutively referred patients with chronic fatigue syndrome; 36 were randomly assigned to immediate cognitive behaviour therapy and 35 to the waiting list for therapy.Intervention 10 sessions of therapy over five months. Treatment protocols depended on the type of activity pattern (relatively active or passive). All participants were assessed again after five months.Main outcome measures Fatigue severity (checklist individual strength), functional impairment (SF-36 physical functioning), and school attendance.Results 62 patients had complete data at five months (29 in the immediate therapy group and 33 on the waiting list). Patients in the therapy group reported significantly greater decrease in fatigue severity (difference in decrease on checklist individual strength was 14.5, 95% confidence interval 7.4 to 21.6) and functional impairment (difference in increase on SF-36 physical functioning was 17.3, 6.2 to 28.4) and their attendance at school increased significantly (difference in increase in percentage school attendance was 18.2, 0.8 to 35.5). They also reported a significant reduction in several accompanying symptoms. Self reported improvement was largest in the therapy group.Conclusion Cognitive behaviour therapy is an effective treatment for chronic fatigue syndrome in adolescents.     

Adjuvant psychological therapy for patients with cancer: a prospective randomised trial.

OBJECTIVE--To determine the effect of adjuvant psychological therapy on the quality of life of patients with cancer. DESIGN--Prospective randomised controlled trial comparing the quality of life of patients receiving psychological therapy with that of patients receiving no therapy, measured before therapy, at eight weeks, and at four months of follow up. SETTING--CRC Psychological Medicine Group of Royal Marsden Hospital. PATIENTS--174 patients aged 18-74 attending hospital with a confirmed diagnosis of malignant disease, a life expectancy of at least 12 months, or scores on various measures of psychological morbidity above previously defined cut off points. INTERVENTION--Adjuvant psychological therapy, a brief, problem focused, cognitive-behavioural treatment programme specifically designed for the needs of individual cancer patients. MAIN OUTCOME MEASURES--Hospital anxiety and depression scale, mental adjustment to cancer scale, Rotterdam symptom checklist, psychosocial adjustment to illness scale. RESULTS--156 (90%) patients completed the eight week trial; follow up data at four months were obtained for 137 patients (79%). At eight weeks, patients receiving therapy had significantly higher scores than control patients on fighting spirit and significantly lower scores on helplessness, anxious preoccupation, and fatalism; anxiety; psychological symptoms; and on orientation towards health care. These differences indicated improvement in each case. At four months, patients receiving therapy had significantly lower scores than controls on anxiety; psychological symptoms; and psychological distress. Clinically, the proportion of severely anxious patients dropped from 46% at baseline to 20% at eight weeks and 20% at four months in the therapy group and from 48% to 41% and to 43% respectively among controls. The proportion of patients with depression was 40% at baseline, 13% at eight weeks, and 18% at four months in the therapy group and 30%, 29%, and 23% respectively in controls. CONCLUSIONS--Adjuvant psychological therapy produces significant improvement in various measures of psychological distress among cancer patients. The effect of therapy observed at eight weeks persists in some but not all measures at four month follow up.     

Specialist nurse support for patients with stroke in the community: a randomised controlled trial.

OBJECTIVE--To evaluate whether specialist nurse visits enhance the social integration and perceived health of patients with stroke or alleviate stress in carers in longer term stroke care. DESIGN--Stratified randomised controlled trial; both groups assessed at time of recruitment and at 3, 6, and 12 months. SETTING--Patients with disability related to new stroke who lived in their own homes in the Bradford Metropolitan District. SUBJECTS--240 patients aged 60 years or over, randomly allocated to control group (n = 120) or intervention group (n = 120). Intervention--Visits by specialist outreach nurses over 12 months to provide information, advice, and support; minimum of six visits during the first six months. The control group received no visits. MAIN OUTCOME MEASURES--The Barthel index (functional ability), the Frenchay activities index (social activity), the Nottingham health profile (perceived health status). Stress among carers was indicated by the general health questionnaire-28 (28 items). The nurses recorded their interventions in trial diaries. RESULTS--There were no significant differences in perceived health, social activities, or stress among carers between the treatment and control groups at any of the assessments points. A subgroup of mildly disabled patients with stroke (Barthel index 15-19) had an improved social outcome at six months (Frenchay activities index, Median difference 3 (95% confidence interval 0 to 6; P = 0.03) and for the full 12 months of follow up (analysis of covariance P = 0.01) compared with the control group. CONCLUSIONS--The specialist nurse intervention resulted in a small improvement in social activities only for the mildly disabled patients. No proved strategy yet exists that can be recommended to address the psychosocial difficulties of patients with stroke and their families.     

Effectiveness of cognitive behaviour therapy for the treatment of catastrophisation in patients with fibromyalgia: a randomised controlled trial

Introduction  

No randomised, controlled trials have been conducted to date on the efficacy of psychological and pharmacological treatments of pain catastrophising (PC) in patients with fibromyalgia. Our aim in this study was to assess the effectiveness of cognitive-behaviour therapy (CBT) and the recommended pharmacological treatment (RPT) compared with treatment as usual (TAU) at the primary care level for the treatment of PC in fibromyalgia patients.     

Heart disease prevention project: a randomised controlled trial in industry.

Twenty-four factories or other occupational groups, employing 18 210 men aged 40 to 59, were formed into matched pairs. One of each pair was allocated randomly to receive a five to six year programme of medical examinations and intervention to reduce the levels of the main coronary risk factors. Men at factories in the intervention group were given advice on dietary reduction of plasma cholesterol concentrations, stopping or reducing cigarette smoking, regular exercies for the sedentary and reduced energy intake for the overweight, and hypertension was treated. The programme was delivered mainly through existing occupational medical services, helped by a small central staff. Personal consultations were largely confined to men with a high risk of developing coronary heart disease. Changes in risk factors were assessed by regular standardised examinations of random samples of men. The spread of information by general propaganda proved easy, but a change in habits seemed to require personal contact. Small but significant reductions occurred, mainly in the high-risk group, but these were not sustained when pressure was relaxed.     

Psychological rehabilitation after myocardial infarction: multicentre randomised controlled trial.

OBJECTIVE: To evaluate rehabilitation after myocardial infarction. DESIGN: Randomised controlled trial of rehabilitation in unselected myocardial infarction patients in six centres, baseline data being collected on admission and by structured interview (of patients and spouses) shortly after discharge and outcome being assessed by structured interview at six months and clinical examination at 12 months. SETTING: Six district general hospitals. SUBJECTS: All 2328 eligible patients admitted over two years with confirmed myocardial infarction and discharged home within 28 days. INTERVENTIONS: Rehabilitation programmes comprising psychological therapy, counselling, relaxation training, and stress management training over seven weekly group outpatient sessions for patients and spouses. MAIN OUTCOME MEASURES: Anxiety, depression, quality of life, morbidity, use of medication, and mortality. RESULTS: At six months there were no significant differences between rehabilitation patients and controls in reported anxiety (prevalence 33%) or depression (19%). Rehabilitation patients reported a lower frequency of angina (median three versus four episodes a week), medication, and physical activity. At 12 months there were no differences in clinical complications, clinical sequelae, or mortality. CONCLUSIONS: Rehabilitation programmes based on psychological therapy, counselling, relaxation training, and stress management seem to offer little objective benefit to patients who have experienced myocardial infarction compared with previous reports of smaller trials.     

Cognitive behavioural therapy versus supportive therapy for persistent positive symptoms in psychotic disorders: The POSITIVE Study, a multicenter, prospective, single-blind, randomised controlled clinical trial

Background

It has been demonstrated that cognitive behavioural therapy (CBT) has a moderate effect on symptom reduction and on general well being of patients suffering from psychosis. However, questions regarding the specific efficacy of CBT, the treatment safety, the cost-effectiveness, and the moderators and mediators of treatment effects are still a major issue. The major objective of this trial is to investigate whether CBT is specifically efficacious in reducing positive symptoms when compared with non-specific supportive therapy (ST) which does not implement CBT-techniques but provides comparable therapeutic attention.

Methods/Design

The POSITIVE study is a multicenter, prospective, single-blind, parallel group, randomised clinical trial, comparing CBT and ST with respect to the efficacy in reducing positive symptoms in psychotic disorders. CBT as well as ST consist of 20 sessions altogether, 165 participants receiving CBT and 165 participants receiving ST. Major methodological aspects of the study are systematic recruitment, explicit inclusion criteria, reliability checks of assessments with control for rater shift, analysis by intention to treat, data management using remote data entry, measures of quality assurance (e.g. on-site monitoring with source data verification, regular query process), advanced statistical analysis, manualized treatment, checks of adherence and competence of therapists. Research relating the psychotherapy process with outcome, neurobiological research addressing basic questions of delusion formation using fMRI and neuropsychological assessment and treatment research investigating adaptations of CBT for adolescents is combined in this network. Problems of transfer into routine clinical care will be identified and addressed by a project focusing on cost efficiency.

Discussion

This clinical trial is part of efforts to intensify psychotherapy research in the field of psychosis in Germany, to contribute to the international discussion on psychotherapy in psychotic disorders, and to help implement psychotherapy in routine care. Furthermore, the study will allow drawing conclusions about the mediators of treatment effects of CBT of psychotic disorders.

Effect of health visitors working with elderly patients in general practice: a randomised controlled trial.

Health visitors were employed specifically to care for two years for a random sample of patients in general practice who were aged over 70. Independent assessments made at the beginning and end of the study showed that the health visitor in an urban practice had some impact on her caseload of patients; she provided more services for them, their mortality was reduced, and their quality of life improved, though the last measure just failed to be statistically significant. The health visitor working in a rural practice had no such effect.     

Components of placebo effect: randomised controlled trial in patients with irritable bowel syndrome

Objective To investigate whether placebo effects can experimentally be separated into the response to three components—assessment and observation, a therapeutic ritual (placebo treatment), and a supportive patient-practitioner relationship—and then progressively combined to produce incremental clinical improvement in patients with irritable bowel syndrome. To assess the relative magnitude of these components.Design A six week single blind three arm randomised controlled trial.Setting Academic medical centre.Participants 262 adults (76% women), mean (SD) age 39 (14), diagnosed by Rome II criteria for and with a score of ≥150 on the symptom severity scale.Interventions For three weeks either waiting list (observation), placebo acupuncture alone (“limited”), or placebo acupuncture with a patient-practitioner relationship augmented by warmth, attention, and confidence (“augmented”). At three weeks, half of the patients were randomly assigned to continue in their originally assigned group for an additional three weeks.Main outcome measures Global improvement scale (range 1-7), adequate relief of symptoms, symptom severity score, and quality of life.Results At three weeks, scores on the global improvement scale were 3.8 (SD 1.0) v 4.3 (SD 1.4) v 5.0 (SD 1.3) for waiting list versus “limited” versus “augmented,” respectively (P<0.001 for trend). The proportion of patients reporting adequate relief showed a similar pattern: 28% on waiting list, 44% in limited group, and 62% in augmented group (P<0.001 for trend). The same trend in response existed in symptom severity score (30 (63) v 42 (67) v 82 (89), P<0.001) and quality of life (3.6 (8.1) v 4.1 (9.4) v 9.3 (14.0), P<0.001). All pairwise comparisons between augmented and limited patient-practitioner relationship were significant: global improvement scale (P<0.001), adequate relief of symptoms (P<0.001), symptom severity score (P=0.007), quality of life (P=0.01).Results were similar at six week follow-up.Conclusion Factors contributing to the placebo effect can be progressively combined in a manner resembling a graded dose escalation of component parts. Non-specific effects can produce statistically and clinically significant outcomes and the patient-practitioner relationship is the most robust component.Trial registration Clinical Trials NCT00065403.     

Effectiveness of teaching general practitioners skills in brief cognitive behaviour therapy to treat patients with depression: randomised controlled trial

ObjectiveTo assess the effectiveness of teaching general practitioners skills in brief cognitive behaviour therapy.DesignParallel group, cluster randomised, controlled trial of an educational package on cognitive behaviour therapy.SettingGeneral practices in north London.Participants84 general practitioner principals and 272 patients attending their practices who scored above the threshold for psychological distress on the hospital anxiety and depression scale.InterventionA training package of four half days on brief cognitive behaviour therapy.ResultsDoctors'' knowledge of depression and attitudes towards its treatment showed no major difference between intervention and control groups after 6 months. The training had no discernible impact on patients'' outcomes.ConclusionGeneral practitioners may require more training and support than a basic educational package on brief cognitive behaviour therapy to acquire skills to help patients with depression.

What is already known on this topic

Trained professionals can deliver effective cognitive behaviour therapy to depressed patients presenting to general practitionersLimited evidence shows that cognitive behaviour therapy is effective when delivered by general practitioners who have received extensive instructionMost doctors do not have the time or inclination to carry out such comprehensive training

What this study adds

Basic training in brief cognitive behaviour therapy has little effect on general practitioners'' attitudes to the identification and treatment of depression or the outcome of their patients with emotional problemsGeneral practitioners may require more extensive training and support if they are to acquire skills in brief cognitive behaviour therapy that will have a positive impact on their patients     

Community mothers' programme: randomised controlled trial of non-professional intervention in parenting.

OBJECTIVE--To see whether non-professional volunteer community mothers could deliver a child development programme to disadvantaged first time mothers for children aged up to 1 year. DESIGN--Randomised controlled trial. SETTING--A regional health authority in Dublin. SUBJECTS--262 first time mothers who were delivered during six months in 1989 and who lived in a deprived area of Dublin; 30 experienced mothers from the same community recruited as community mothers. INTERVENTIONS--All the first time mothers received standard support from the public health nurse. In addition, those in the intervention group received the services of a community mother, who was scheduled to visit monthly during the first year of the child''s life. RESULTS--232 (89%) first time mothers completed the study--127 in the intervention group, 105 controls. At the end of the study children in the intervention group were more likely to have received all of their primary immunisations, to be read to, and to be read to daily, played more cognitive games; and were exposed to more nursery rhymes. They were less likely to begin cows'' milk before 26 weeks and to receive an inappropriate energy intake and inappropriate amounts of animal protein, non-animal protein, wholefoods, vegetables, fruit, and milk. Mothers in the intervention group also had a better diet than controls. At the end of the study they were less likely to be tired, feel miserable, and want to stay indoors; had more positive feelings; and were less likely to display negative feelings. CONCLUSION--Non-professionals can deliver a health promotion programme on child development effectively. Whether they can do so as effectively as professionals requires further study.     

"Right" stay in hospital after sugery: randomised controlled trial.

A randomised controlled trial was carried out on 100 patients to compare the effects of discharge after certain pre-specified clinical criteria had been fulfilled--"right" stay--with those of discharge at an arbitrary 10 days after surgery--"fixed" stay. The operations concerned (cholecystectomy and vagotomy) were more hazardous than those previously included in studies of early discharge. Patients in the right-stay group were discharged, on average, 7-6 days after operation--that is, two days earlier than those in the fixed-stay group. In terms of clinical progress, social factors such as return to work, and the acceptability to patients and relatives of the implications of right stay, patients in this group fared as well as those in the fixed-stay group, and in some respects slightly better. Right stay entailed the transfer of some work from hospital to community medical and nursing staff, but this also was acceptable. The concept and use of the right-stay principle is of value in planning the postoperative discharge of suitable patients.     

Blood pressure reduction in elderly: a randomised controlled trial of methyldopa.

A total of 123 out of 549 elderly residents of local authority welfare homes in Nottinghamshire were found at screening to have a standing or lying diastolic blood pressure of 100 mm Hg or more. These 123 subjects were randomly allocated to simple observation or to treatment with methyldopa. The cumulative mortality was similar in the observed and treated groups and in the normotensive group from which the subjects had been separated. Thus moderate hypertension, whether treated or not, was not a major risk predictor in the elderly population studied.     

Zinc supplementation during pregnancy: a double blind randomised controlled trial.

OBJECTIVE--To see whether zinc supplementation during pregnancy improves maternal and fetal outcome. DESIGN--Prospective study started at booking and continued till discharge of mother and baby from the maternity hospital. Mothers were randomly assigned to receive zinc supplementation or placebo in a double blind trial. SETTING--Mothers booking at one hospital. PATIENTS--Women booking before 20 weeks of gestation who agreed to take part in the study. 494 Mothers were followed up till the end of pregnancy. There was no difference between the groups given zinc and placebo in their social or medical backgrounds. INTERVENTIONS--Mothers in the active treatment group received one capsule of 20 mg elemental zinc daily and those in the placebo treated group a capsule identical in appearance and taste with the active capsule but which contained inert substances. MAIN OUTCOME MEASURE--Various adverse outcomes were tested, including maternal bleeding, hypertension, complications of labour and delivery, gestational age, Apgar scores, and neonatal abnormalities. The main outcome measure was birth weight. RESULTS--There were no differences whatsoever between mothers given a zinc supplement and those given a placebo. CONCLUSION--Zinc supplementation in pregnancy in the United Kingdom does not seem to offer any benefits to the mother or her fetus.
