Summary Background Deep vein thrombosis (DVT) and pulmonary embolism are common after stroke. In small trials of patients undergoing surgery, graduated compression stockings (GCS) reduce the risk of DVT. National stroke guidelines extrapolating from these trials recommend their use in patients with stroke despite insufficient evidence. We assessed the effectiveness of thigh-length GCS to reduce DVT after stroke. Methods In this outcome-blinded, randomised controlled trial, 2518 patients who were admitted to hospital within 1 week of an acute stroke and who were immobile were enrolled from 64 centres in the UK, Italy, and Australia. Patients were allocated via a central randomisation system to routine care plus thigh-length GCS (n=1256) or to routine care plus avoidance of GCS (n=1262). A technician who was blinded to treatment allocation undertook compression Doppler ultrasound of both legs at about 7–10 days and, when practical, again at 25–30 days after enrolment. The primary outcome was the occurrence of symptomatic or asymptomatic DVT in the popliteal or femoral veins. Analyses were by intention to treat. This study is registered, number ISRCTN28163533. Findings All patients were included in the analyses. The primary outcome occurred in 126 (10·0%) patients allocated to thigh-length GCS and in 133 (10·5%) allocated to avoid GCS, resulting in a non-significant absolute reduction in risk of 0·5% (95% CI −1·9% to 2·9%). Skin breaks, ulcers, blisters, and skin necrosis were significantly more common in patients allocated to GCS than in those allocated to avoid their use (64 [5%] vs 16 [1%]; odds ratio 4·18, 95% CI 2·40–7·27). Interpretation These data do not lend support to the use of thigh-length GCS in patients admitted to hospital with acute stroke. National guidelines for stroke might need to be revised on the basis of these results.

BACKGROUNDnGraduated compression stockings are widely used for deep venous thrombosis (DVT) prophylaxis. Although below-knee stockings are used more often than thigh-length stockings, no reliable evidence indicates that they are as effective as thigh-length stockings.nnnOBJECTIVEnTo compare the effectiveness of thigh-length stockings with that of below-knee stockings for preventing proximal DVT in immobile, hospitalized patients with stroke.nnnDESIGNnParallel-group trial with centralized randomization (minimization within centers) to ensure allocation concealment. The ultrasonographers who looked for DVT were blinded, but the patients and caregivers were not. (Controlled-trials.com registration number: ISRCTN28163533)nnnSETTINGn112 hospitals in 9 countries.nnnPATIENTSn3114 immobile patients hospitalized with acute stroke between January 2002 and May 2009.nnnINTERVENTIONn1552 patients received thigh-length stockings and 1562 patients received below-knee stockings to wear while they were in the hospital.nnnMEASUREMENTSnUltrasonographers performed compression duplex ultrasonography in 1406 patients (96% of survivors) in each treatment group between 7 and 10 days after enrollment. They performed a second scan in 643 patients in the thigh-length stockings group and 639 in the below-knee stockings group at about 25 to 30 days. The primary outcome was symptomatic or asymptomatic DVT in the popliteal or femoral veins, detected on either scan.nnnRESULTSnPatients were retained in their assigned group for all analyses. The primary outcome occurred in 98 patients (6.3%) who received thigh-length stockings and 138 (8.8%) who received below-knee stockings (absolute difference, 2.5 percentage points [95% CI, 0.7 to 4.4 percentage points]; P = 0.008), an odds reduction of 31% (CI, 9% to 47%). Seventy-five percent of patients in both groups wore the stockings for 30 days or until they were discharged, died, or regained mobility. Skin breaks occurred in 61 patients who received thigh-length stockings (3.9%) and 45 (2.9%) who received below-knee stockings.nnnLIMITATIONnBlinding was incomplete, 2 scans were not obtained for all enrolled patients, and the trial was stopped before the target accrual was reached.nnnCONCLUSIONnProximal DVT occurs more often in patients with stroke who wear below-knee stockings than in those who wear thigh-length stockings.nnnPRIMARY FUNDING SOURCEnMedical Research Council of the United Kingdom, Chief Scientist Office of the Scottish Government, and Chest Heart and Stroke Scotland.

Quality of life and measures of quality of life in patients with neuromuscular disorders.

Ted M. Burns; Christopher D. Graham; Michael R. Rose; Zachary Simmons

In this review we present an overview of quality of life (QOL) and QOL measures in neuromuscular disorders. We discuss the characteristics of QOL measures used in neuromuscular research, highlighting differences between generic versus disease‐specific and global versus health‐related QOL instruments. The phenomenon of response shift is reviewed. Commonly used QOL instruments are reviewed for amyotrophic lateral sclerosis, muscle diseases, myasthenia gravis, and polyneuropathy. We also review some of what is known about QOL for patients with these neuromuscular disorders. Muscle Nerve 46: 9–25, 2012

A systematic review of quality of life in adults with muscle disease

Christopher D. Graham; Michael R. Rose; Elizabeth A. Grunfeld; Simon D. Kyle; John Weinman

We reviewed the literature on how muscle disease affects quality of life compared to healthy controls, and the factors that influence the effects of muscle disease on quality of life. We also wanted to know whether quality of life differed between muscle diseases. We searched online databases and identified 26 relevant studies. The quality of each study was assessed, results sections analysed and a database of factors associated with quality of life developed. We graded the level of evidence supporting the association between each factor and quality of life as inconclusive, moderate or high. Compared to controls, muscle disease compromised quality of life in all areas of functioning. There was little evidence to suggest that quality of life differed significantly between muscle diseases. There was a high level of evidence suggesting that disease severity, pain, fatigue, and mood significantly affect quality of life. There was a moderate level of evidence suggesting that illness perceptions, coping strategies, age and gender affect quality of life. Several factors had an inconsistent level of evidence.

Do patients whose psychogenic non-epileptic seizures resolve, ‘replace’ them with other medically unexplained symptoms? Medically unexplained symptoms arising after a diagnosis of psychogenic non-epileptic seizures

Paul S. McKenzie; Maria Oto; Christopher D. Graham; Roderick Duncan

Background In clinical practice, it is sometimes observed that patients in whom psychogenic non-epileptic seizures (PNES) cease, develop another medically unexplained symptom (MUS). Methods In order to determine how many patients develop new MUS post diagnosis and whether patients whose attacks cease are more likely to do so, new MUS were recorded 6–12u2005months after the diagnosis of PNES in 187 consecutive patients. Results Compared with baseline, the overall proportion of patients with MUS increased slightly, from 70.1% to 76.5%, with 44/187 patients (23.5%) developing new MUS. There were no significant differences between attack free and non-attack free patients. Binary logistic regression analysis showed that predictors of new MUS diverged between attack free and non-attack free patients. Among patients continuing to have attacks, those with previous health related psychological trauma were 18.00 times more likely to develop new MUS (p<0.0005). In patients who became attack free, patients drawing disability benefits were 5.04 times more likely to have new MUS (p=0.011). Conclusions The results suggest that almost 25% of patients develop new MUS following a diagnosis of PNES, although most of those have MUS pre-diagnosis. Patients with a history of health related psychological trauma whose attacks continue after diagnosis are at particularly high risk of developing new MUS. The data do not support the hypothesis that PNES that resolve are likely to be ‘replaced’ by other MUS.

A systematic review of the use of Acceptance and Commitment Therapy (ACT) in chronic disease and long-term conditions

Christopher D. Graham; Joanna Gouick; Charlotte Krahé; David Gillanders

Many have proposed that Acceptance and Commitment Therapy (ACT) may be particularly effective for improving outcomes in chronic disease/long-term conditions, and ACT techniques are now being used clinically. However, reviews of ACT in this context are lacking, and the state of evidence is unclear. This systematic review aimed to: collate all ACT interventions with chronic disease/long-term conditions, evaluate their quality, and comment on efficacy. Ovid MEDLINE, EMBASE and Psych Info were searched. Studies with solely mental health or chronic pain populations were excluded. Study quality was then rated, with a proportion re-rated by a second researcher. Eighteen studies were included: eight were randomised controlled trials (RCTs), four used pre-post designs, and six were case studies. A broad range of applications was observed (e.g. improving quality of life and symptom control, reducing distress) across many diseases/conditions (e.g. HIV, cancer, epilepsy). However, study quality was generally low, and many interventions were of low intensity. The small number of RCTs per application and lower study quality emphasise that ACT is not yet a well-established intervention for chronic disease/long-term conditions. However, there was some promising data supporting certain applications: parenting of children with long-term conditions, seizure-control in epilepsy, psychological flexibility, and possibly disease self-management.

INTRODUCTIONnPulmonary Rehabilitation (PR) reduces hospital admissions following an acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD) but adherence is known to be poor. Patients illness perceptions may affect adherence to disease-management strategies but to date have not been explored following an exacerbation. The study aim is two-fold; firstly to prospectively explore acceptance and uptake of post-exacerbation PR and secondly to identify possible clusters of patients illness perceptions following hospitalisation for an exacerbation of COPD.nnnMETHODSnPatients admitted to hospital with an exacerbation of COPD were recruited to a prospective observational study. Self-reported illness perceptions, mood, health status and self-efficacy were assessed. Acceptance and uptake of PR were recorded at six months. Cluster analysis of Illness Perceptions Questionnaire-Revised data was used to establish groups of patients holding distinct beliefs.nnnRESULTSn128 patients were recruited. Acceptance and uptake of PR following an acute exacerbation was poor with only 9% (nxa0=xa011) completing the programme. Cluster analysis revealed three distinct groups: Cluster 1 in control (nxa0=xa052), Cluster 2 disengaged (nxa0=xa036) and Cluster 3 distressed (nxa0=xa040). Significant between-cluster differences were observed in mood, health status and self-efficacy (pxa0<xa00.01). Acceptance and uptake of PR did not differ between clusters.nnnCONCLUSIONSnAcceptance/uptake of post-exacerbation PR was found to be poor. Three distinct illness schema exist in patients following an acute exacerbation. This information may be useful in developing novel psychologically-informed interventions designed to reduce feelings of distress and perhaps facilitate a PR intervention for this vulnerable population.

Objective: To replicate the finding that illness perceptions influence quality of life in adults with muscle disease and to explore the additional influence of coping and optimism on quality of life and mood. Design: A postal survey including questionnaires recording quality of life, mood, illness perceptions, optimism, coping and functional impairment. Setting: National Health Service muscle clinics in the United Kingdom. Participants: A convenience sample of adults with muscle disease. Interventions: Not applicable. Main outcome measures: Individualised Neuromuscular Quality of Life Questionnaire, Hospital Anxiety and Depression Scale. Results: A total of 226 completed questionnaires were returned. Although functional impairment explained most of the variance in three out of eight quality of life domains, psychological factors explained greater amounts of variance (between 19% and 52% of variance) in all other quality of life domains and in both mood domains (between 45% and 48% of variance). Overall, illness perceptions explained much of the variance in quality of life and mood score (between 5% and 37% of variance), while coping (up to 8% of variance) and optimism (up to 15% of variance) explained smaller amounts of variance. Conclusion: The results confirm that illness perceptions are associated with quality of life in muscle disease and suggest that they also influence mood. The addition of optimism and coping variables into the analysis yielded small increases in the proportions of variance in quality of life and mood which were explained. These results have implications for the composition of future psychological interventions.

Primary and secondary care attendance, anticonvulsant and antidepressant use and psychiatric contact 5–10 years after diagnosis in 188 patients with psychogenic non-epileptic seizures

Roderick Duncan; Christopher D. Graham; Maria Oto; Aline Russell; Laura McKernan; Sue Copstick

Background and objectives There have been few studies of long-term outcome in psychogenic non-epileptic seizures (PNES), and none of long-term healthcare utilization. Methods We studied attendance with seizures, healthcare use and employment over a 6-month period from the family doctors of 260 consecutive patients with psychogenic non-epileptic seizures (PNES), 5–10u2005years after diagnosis. Results We obtained clinical data in 188/260 patients (72.3%), of whom 60 (31.9%) had attended primary or secondary care with seizures in the previous 6u2005months. Predictors of attendance with seizures included a diagnosis of epilepsy+PNES (OR 5.7, p=0.009), work status (OR 3.9, p=0.027) and social security payments (OR 6.3, p=0.003). Latency to diagnosis was not predictive. Emergency admission data were available in 187 patients, of whom 25 (13.4%) had emergency hospital attendances. Prescription data were available for 172 patients, of whom 154 had ‘PNES only’. Of these, 17 (11.0%) remained on antiepileptic medication (AED). 68/172 patients (39.5%) were prescribed antidepressant (AD) drugs. We had psychiatric contact data in 185 patients, of whom 49 (26.5%) had accessed psychiatric services in the last 6u2005months. Conclusions Surprisingly few of our patients had presented with seizures during the study period. Early reductions in both AED use and healthcare use were sustained long term. Although psychiatric and employment outcomes were less encouraging, some aspects of PNES outcome may be better than previously thought.

The potential of psychological interventions to improve quality of life and mood in muscle disorders

Christopher D. Graham; Zachary Simmons; Simon R. Stuart; Michael R. Rose

Quality of life (QoL) and mood are reduced in many patients with muscle disorders. Psychological variables appear to be contributors to both QoL and mood, suggesting that psychological interventions could improve these outcomes, yet research in this area is sparse. We review the roles of psychological variables, plus context and disease severity, in explaining QoL. A cognitive‐behavioral model of disease self‐management, with acceptance as the central component, is discussed. This model is then used to describe how psychological interventions derived from cognitive behavioral therapy (CBT), in particular Acceptance and Commitment Therapy (ACT), might be applied to address the issues of distress, nonadherence to treatments, pain, and fatigue in people with muscle disorders.
