Self-management interventions for chronic illness

An increasing number of interventions have been developed for patients to better manage their chronic illnesses. They are characterised by substantial responsibility taken by patients, and are commonly referred to as self-management interventions. We examine the background, content, and efficacy of such interventions for type 2 diabetes, arthritis, and asthma. Although the content and intensity of the programmes were affected by the objectives of management of the illness, the interventions differed substantially even within the three illnesses. When comparing across conditions, it is important to recognise the different objectives of the interventions and the complexity of the issues that they are attempting to tackle. For both diabetes and asthma, the objectives are concerned with the underlying control of the condition with clear strategies to achieve the desired outcome. By contrast, strategies to deal with symptoms of pain and the consequences of disability in arthritis can be more complex. The interventions that were efficacious provide some guidance as to the components needed in future programmes to achieve the best results. But to ensure that these results endure over time remains an important issue for self-management interventions.

A systematic review of psychosocial outcomes following education, self-management and psychological interventions in diabetes mellitus

Self-management and psychological interventions for diabetes have become increasingly common and have shown some positive impact on glycemic control. The association of such interventions with psychosocial outcomes is however, less clear. The current review examines the impact of these interventions on psychosocial outcomes including depression, anxiety, adjustment and quality of life. A systematic search of the literature was performed on Medline, Embase and Psychlit. Reference lists were screened for studies that met inclusion/exclusion criteria. Studies were coded on outcomes both over time and relative to control groups. In addition studies were classified as being principally educational, self-management or psychological in type, and the different components in the intervention were determined. Thirty-six studies were identified. Detrimental effects were not generally seen following any type of intervention. Depression seemed to be particularly improved following psychological interventions, whilst quality of life improved more following self-management interventions. A number of methodological issues, such as the specificity of measure used, characteristics of the population and type of intervention were however, influential in the impact of interventions on outcomes. It is recommended that future studies would benefit from being larger with controlled designs, using diabetes specific measures and providing clearer descriptions of intervention components. This will allow greater understanding of what contexts different interventions are most suited to, and which components are key to, improving psychological well-being and quality of life.

Lifestyle changes for improving disease-specific quality of life in sedentary men on long-term androgen-deprivation therapy for advanced prostate cancer: a randomised controlled trial

BACKGROUND Prostate cancer is a key driver of cancer-related global disability-adjusted life-years. Androgen-deprivation therapy (ADT) for advanced disease is linked to fatigue, reduced physical function, and quality of life (QoL). OBJECTIVE To evaluate the effect of a lifestyle intervention on disease-specific QoL, diastolic blood pressure, and cancer-related fatigue in sedentary men receiving long-term ADT for advanced prostate cancer. DESIGN, SETTING, AND PARTICIPANTS A total of 100 hundred sedentary men with locally advanced or metastatic prostate cancer on long-term ADT were randomised to an intervention or usual care group. INTERVENTION A 12-wk lifestyle intervention consisting of aerobic and resistance exercise with parallel dietary advice. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Disease-specific QoL was measured using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) and Functional Assessment of Cancer Therapy-Fatigue (FACT-F) questionnaires at 12 wk postintervention and at 6 mo following withdrawal of support. Analysis of covariance and mixed regression were conducted. RESULTS AND LIMITATIONS Clinically relevant improvements in FACT-P were seen at 12 wk in the intervention group compared with controls (mean difference: 8.9 points; 95% confidence interval [CI], 3.7-14.2; adjusted p=0.001). No difference was apparent at 6 mo (mean difference: 3.3 points; 95% CI, -2.6 to 9.3; adjusted p=0.27). No difference in diastolic blood pressure was seen at either follow-up (all p > 0.05). Clinically relevant improvements in FACT-F were seen at 12 wk (mean difference: 5.3 points; 95% CI, 2.7-7.9; adjusted p<0.001) and maintained following withdrawal of supervision (mean difference: 3.9 points; 95% CI, 1.1-6.8; adjusted p=0.007). Improvements in exercise tolerance and behaviour were maintained at 6 mo (adjusted p<0.001 and 0.038). CONCLUSIONS A lifestyle intervention resulted in a clinically meaningful improvement in disease-specific QoL that was not maintained postintervention. No effect on blood pressure occurred. Durability of response was seen in fatigue and exercise behaviour. Further evaluation of support structures is essential. TRIAL REGISTRATION ISRCTN88605738.

Self management for men with lower urinary tract symptoms: randomised controlled trial

Objective To evaluate the effectiveness of self management as a first line intervention for men with lower urinary tract symptoms. Design Randomised controlled trial. Setting A teaching hospital and a district general hospital in London. Participants 140 men (mean age 63 (SD 10.7) years), recruited between January 2003 and April 2004, referred by general practitioners to urological outpatient departments with uncomplicated lower urinary tract symptoms. Interventions Self management and standard care (n=73) or standard care alone (n=67). The self management group took part in three small group sessions comprising education, lifestyle advice, and training in problem solving and goal setting skills. Main outcome measures The primary outcome measure was treatment failure measured at 3, 6, and 12 months. Symptom severity (international prostate symptom score; higher scores represent a poorer outcome) was used as a secondary outcome. Results At three months, treatment failure had occurred in 7 (10%) of the self management group and in 27 (42%) of the standard care group (difference=32%, 95% confidence interval 18% to 46%). Corresponding differences in the frequency of treatment failure were 42% (27% to 57%) at six months and 48% (32% to 64%) at 12 months. At three months, the mean international prostate symptom score was 10.7 in the self management group and 16.4 in the standard care group (difference=5.7, 3.7 to 7.7). Corresponding differences in score were 6.5 (4.3 to 8.7) at six months and 5.1 (2.7 to 7.6) at 12 months. Conclusions Self management significantly reduced the frequency of treatment failure and reduced urinary symptoms. Because of the large observed benefit of self management, the results of this study support the case for a large multicentre trial to confirm whether self management could be considered as first line treatment for men with lower urinary tract symptoms.

The role of apolipoprotein E in cognitive decline after cardiac operation

BACKGROUND Recently, Tardiff and colleagues have suggested that the presence of the apolipoprotein E, epsilon4 allele was associated with increased likelihood of cognitive decline after coronary artery bypass grafting. The objective of the current study was to replicate this earlier work using an increased sample size. The increased sample also enabled an analysis by individual genotype in cognitive decline after coronary artery bypass grafting. METHODS Apolipoprotein E genotyping was performed on 111 individuals undergoing coronary artery bypass grafting. Each participant underwent a battery of nine neuropsychological tests before operation and 4 to 7 weeks after operation. RESULTS Cognitive decline, assessed by both continuous Z change scores and two categoric measures of cognitive deficit, was not significantly associated with either individual apolipoprotein E genotypes or categorization by the presence or absence of the epsilon4 allele. The examination of potential moderating factors did not alter this finding. CONCLUSIONS This study suggests that the epsilon4 allele is not associated with cognitive decline in the weeks after coronary artery bypass grafting.

Exercise for Men with Prostate Cancer: A Systematic Review and Meta-analysis

CONTEXT Exercise could be beneficial for prostate cancer survivors. However, no systematic review across cancer stages and treatment types addressing potential benefits and harms exists to date. OBJECTIVE To assess the effects of exercise on cancer-specific quality of life and adverse events in prostate cancer trials. EVIDENCE ACQUISITION We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, AMED, CINAHL, PsycINFO, SPORTDiscus, and PEDro. We also searched grey literature databases, including trial registers. Searches were from database inception to March 2015. Standardised mean differences (SMDs) were calculated for meta-analysis. EVIDENCE SYNTHESIS We included 16 randomised controlled trials (RCTs) involving 1574 men with prostate cancer. Follow-up varied from 8 wk to 12 mo. RCTs involved men with stage I-IV cancers. A high risk of bias was frequently due to problematic intervention adherence. Seven trials involving 912 men measured cancer-specific quality of life. Pooling of the data from these seven trials revealed no significant effect on this outcome (SMD 0.13, 95% confidence interval [CI] -0.08 to 0.34, median follow-up 12 wk). Sensitivity analysis of studies that were judged to be of high quality indicated a moderate positive effect estimate (SMD 0.33, 95% CI 0.08-0.58; median follow-up 12 wk). Similar beneficial effects were seen for cancer-specific fatigue, submaximal fitness, and lower body strength. We found no evidence of benefit for disease progression, cardiovascular health, or sexual function. There were no deaths attributable to exercise interventions. Other serious adverse events (eg, myocardial infarction) were equivalent to those seen in controls. CONCLUSIONS These results support the hypothesis that exercise interventions improve cancer-specific quality of life, cancer-specific fatigue, submaximal fitness, and lower body strength. PATIENT SUMMARY This review shows that exercise/physical activity interventions can improve quality of life, fatigue, fitness, and function for men with prostate cancer.

Interventions to improve exercise behaviour in sedentary people living with and beyond cancer: a systematic review.

Background:To systematically review the effects of interventions to improve exercise behaviour in sedentary people living with and beyond cancer.Methods:Only randomised controlled trials (RCTs) that compared an exercise intervention to a usual care comparison in sedentary people with a homogeneous primary cancer diagnosis, over the age of 18 years were eligible. The following electronic databases were searched: Cochrane Central Register of Controlled Trials MEDLINE; EMBASE; AMED; CINAHL; PsycINFO; SportDiscus; PEDro from inception to August 2012.Results:Fourteen trials were included in this review, involving a total of 648 participants. Just six trials incorporated prescriptions that would meet current recommendations for aerobic exercise. However, none of the trials included in this review reported intervention adherence of 75% or more for a set prescription that would meet current aerobic exercise guidelines. Despite uncertainty around adherence in many of the included trials, the interventions caused improvements in aerobic exercise tolerance at 8–12 weeks (SMD=0.73, 95% CI=0.51–0.95) in intervention participants compared with controls. At 6 months, aerobic exercise tolerance is also improved (SMD=0.70, 95% CI=0.45–0.94), although four of the five trials had a high risk of bias; hence, caution is warranted in its interpretation.Conclusion:Expecting the majority of sedentary survivors to achieve the current exercise guidelines is likely to be unrealistic. As with all well-designed exercise programmes, prescriptions should be designed around individual capabilities and frequency, duration and intensity or sets, repetitions, intensity of resistance training should be generated on this basis.

Evaluation of the UCL Diabetes Self-management Programme (UCL-DSMP): A Randomized Controlled Trial

Self-management has been described as the cornerstone of care for diabetes. Many self-management studies are limited by poor methodology and poor descriptions of the intervention. The current study developed a theoretically based self-management programme for patients with type 2 diabetes, which was evaluated via a randomized controlled trial. At immediate post-intervention and three-month follow-up the intervention group showed significant improvement relative to controls on self-management behaviours, quality of life and illness beliefs. A trend towards improved HbA1c was also observed. Documentation in a manual and development of a training programme for facilitators ensures the programme is replicable.

An examination of the self‐regulation model in atrial fibrillation

Objectives. To examine the role of the presence of symptoms on illness representations. To examine the success of the Self-Regulation Model in explaining psychosocial adjustment in patients with atrial fibrillation (AF). Design. A cross-sectional study of 62 AF patients attending either specialized AF or cardiac out-patient clinics. Method. Individuals were classified as symptomatic or asymptomatic and completed the Illness Perception Questionnaire (IPQ), COPE, and Psychosocial Adjustment to Illness Scale (PAIS). Comparisons between groups and explanation of psychosocial adjustment were examined. Results. Symptomatic and asymptomatic participants did not differ on subscales of the IPQ, with the exception of identity. Both symptom status and IPQ subscales explained independent and significant amounts of variance in PAIS domains. In contrast the COPE accounted for minimal amounts of variance in all PAIS domains. Conclusions. The presence of symptoms is not directly influential in the elaboration of the illness representation. Both symptoms and illness representations should be targeted in interventions to improve adjustment to AF.

Community pharmacy-delivered interventions for public health priorities: a systematic review of interventions for alcohol reduction, smoking cessation and weight management, including meta-analysis for smoking cessation

Objectives To systematically review the effectiveness of community pharmacy-delivered interventions for alcohol reduction, smoking cessation and weight management. Design Systematic review and meta-analyses. 10 electronic databases were searched from inception to May 2014. Eligibility criteria for selecting studies Study design: randomised and non-randomised controlled trials; controlled before/after studies, interrupted times series. Intervention: any relevant intervention set in a community pharmacy, delivered by the pharmacy team. No restrictions on duration, country, age, or language. Results 19 studies were included: 2 alcohol reduction, 12 smoking cessation and 5 weight management. Study quality rating: 6 ‘strong’, 4 ‘moderate’ and 9 ‘weak’. 8 studies were conducted in the UK, 4 in the USA, 2 in Australia, 1 each in 5 other countries. Evidence from 2 alcohol-reduction interventions was limited. Behavioural support and/or nicotine replacement therapy are effective and cost-effective for smoking cessation: pooled OR was 2.56 (95% CI 1.45 to 4.53) for active intervention vs usual care. Pharmacy-based interventions produced similar weight loss compared with active interventions in other primary care settings; however, weight loss was not sustained longer term in a range of primary care and commercial settings compared with control. Pharmacy-based weight management interventions have similar provider costs to those delivered in other primary care settings, which are greater than those delivered by commercial organisations. Very few studies explored if and how sociodemographic or socioeconomic variables moderated intervention effects. Insufficient information was available to examine relationships between effectiveness and behaviour change strategies, implementation factors, or organisation and delivery of interventions. Conclusions Community pharmacy-delivered interventions are effective for smoking cessation, and demonstrate that the pharmacy is a feasible option for weight management interventions. Given the potential reach, effectiveness and associated costs of these interventions, commissioners should consider using community pharmacies to help deliver public health services.
