The effectiveness of exercise interventions for people with Parkinson's disease: A systematic review and meta‐analysis

Parkinsons disease (PD) is a neurodegenerative disorder affecting the physical, psychological, social, and functional status of individuals. Exercise programs may be an effective strategy to delay or reverse functional decline for people with PD and a large body of empirical evidence has emerged in recent years. The objective is to systematically review randomized controlled trials (RCTs) reporting on the effectiveness of exercise interventions on outcomes (physical, psychological or social functioning, or quality of life) for people with PD. RCTs meeting the inclusion criteria were identified by systematic searching of electronic databases. Key data were extracted by two independent researchers. A mixed methods approach was undertaken using narrative, vote counting, and random effects meta‐analysis methods. Fourteen RCTs were included and the methodological quality of most studies was moderate. Evidence supported exercise as being beneficial with regards to physical functioning, health‐related quality of life, strength, balance and gait speed for people with PD. There was insufficient evidence support or refute the value of exercise in reducing falls or depression. This review found evidence of the potential benefits of exercise for people with PD, although further good quality research is needed. Questions remain around the optimal content of exercise interventions (dosing, component exercises) at different stages of the disease.

Interventions targeting social isolation in older people: a systematic review

BackgroundTargeting social isolation in older people is a growing public health concern. The proportion of older people in society has increased in recent decades, and it is estimated that approximately 25% of the population will be aged 60 or above within the next 20 to 40 years. Social isolation is prevalent amongst older people and evidence indicates the detrimental effect that it can have on health and wellbeing. The aim of this review was to assess the effectiveness of interventions designed to alleviate social isolation and loneliness in older people.MethodsRelevant electronic databases (MEDLINE, EMBASE, ASSIA, IBSS, PsycINFO, PubMed, DARE, Social Care Online, the Cochrane Library and CINAHL) were systematically searched using an extensive search strategy, for randomised controlled trials and quasi-experimental studies published in English before May 2009. Additional articles were identified through citation tracking. Studies were included if they related to older people, if the intervention aimed to alleviate social isolation and loneliness, if intervention participants were compared against inactive controls and, if treatment effects were reported. Two independent reviewers extracted data using a standardised form. Narrative synthesis and vote-counting methods were used to summarise and interpret study data.ResultsThirty two studies were included in the review. There was evidence of substantial heterogeneity in the interventions delivered and the overall quality of included studies indicated a medium to high risk of bias. Across the three domains of social, mental and physical health, 79% of group-based interventions and 55% of one-to-one interventions reported at least one improved participant outcome. Over 80% of participatory interventions produced beneficial effects across the same domains, compared with 44% of those categorised as non-participatory. Of interventions categorised as having a theoretical basis, 87% reported beneficial effects across the three domains compared with 59% of interventions with no evident theoretical foundation. Regarding intervention type, 86% of those providing activities and 80% of those providing support resulted in improved participant outcomes, compared with 60% of home visiting and 25% of internet training interventions. Fifty eight percent of interventions that explicitly targeted socially isolated or lonely older people reported positive outcomes, compared with 80% of studies with no explicit targeting.ConclusionsMore, well-conducted studies of the effectiveness of social interventions for alleviating social isolation are needed to improve the evidence base. However, it appeared that common characteristics of effective interventions were those developed within the context of a theoretical basis, and those offering social activity and/or support within a group format. Interventions in which older people are active participants also appeared more likely to be effective. Future interventions incorporating all of these characteristics may therefore be more successful in targeting social isolation in older people.

Acupuncture and dry needling in the management of myofascial trigger point pain: A systematic review and meta-analysis of randomised controlled trials

Pain from myofascial trigger points is often treated by needling, with or without injection, although evidence is inconclusive on whether this is effective. We aimed to review the current evidence on needling without injection, by conducting a systematic literature review.

Variability of criteria used to diagnose myofascial trigger point pain syndrome- : Evidence from a review of the literature

ObjectivesThe aim of the literature review was to investigate the criteria adopted by “experts” to diagnose myofascial trigger point (MTrP) pain syndrome. Experts were defined as being either researchers investigating MTrP pain syndrome or the “authority” the researchers cited as a source of reference for MTrP pain syndrome diagnosis. MethodsWe searched electronic databases to identify relevant empirical research (excluding studies not in English and those relating to dental pathology). Of 607 possibly relevant publications 93 met our inclusion criteria. We recorded (1) the individual criterion and criteria combinations used to diagnose MTrP pain syndrome; (2) the cited “authoritative” publications and (3) the criteria recommended by the authoritative publications as being essential for MTrP pain syndrome diagnosis. ResultsThe review identified 19 different diagnostic criteria. The 4 most commonly applied criteria were: “tender spot in a taut band” of skeletal muscle, “patient pain recognition,” “predicted pain referral pattern,” and “local twitch response.” There was no consistent pattern to the choice of specific diagnostic criteria or their combinations. However, one pair of criteria “tender point in a taut band” and “predicted or recognized pain referral” were used by over half the studies. The great majority of studies cited publications by Travell and more recently Simons as a principal authoritative source for MTrP pain syndrome diagnosis, yet most of these studies failed to apply the diagnostic criteria as described by these authorities. DiscussionWe conclude that there is as yet limited consensus on case definition in respect of MTrP pain syndrome. Further research is needed to test the reliability and validity of diagnostic criteria. Until reliable diagnostic criteria have been established, there is a need for greater transparency in research papers on how a case of MTrP pain syndrome is defined, and claims for effective interventions in treating the condition should be viewed with caution.

Hospital at home or acute hospital care? A cost minimisation analysis

Abstract Objective: To compare, from the viewpoints of the NHS and social services and of patients, the costs associated with early discharge to a hospital at home scheme and those associated with continued care in an acute hospital. Design: Cost minimisation analysis. Setting: Acute hospital wards and the community in the north of Bristol (population about 224 000). Subjects: 241 hospitalised but medically stable elderly patients who fulfilled the criteria for early discharge to a hospital at home scheme and who consented to participate. Main outcome measures: Costs to the NHS, social services, and patients over the 3 months after randomisation. Results:The mean cost for hospital at home patients over the 3 months was £2516, whereas that for hospital patients was £3292. Under all the assumptions used in the sensitivity analysis, the cost of hospital at home care was less than that of hospital care. Only when hospital costs were assumed to be less than 50% of those used in the initial analysis was the difference equivocal. Conclusions: The hospital at home scheme is less costly than care in the acute hospital. These results may be generalisable to schemes of similar size and scope, operating in a similar context of rising acute admissions. Key messages Some economic evaluations have found that hospital at home care is more costly than acute hospital care in the United Kingdom, and others have found that it is less costly Cost minimisation analysis found a mean cost to the NHS and social services of £2516 per hospital at home patient and £3292 per hospital patient For every £10 000 spent, routine hospital care could be provided for three patients, while early discharge to care in the hospital at home scheme could be provided for four patients Sensitivity analysis (making differing assumptions for the cost of both services within reasonable boundaries) does not change the result that hospital at home is less costly than hospital care; only when hospital costs are assumed to be less than 50% of the original estimate does the difference become equivocal Costs to patients were similar in the two arms of the trial

The impact of social isolation on the health status and health-related quality of life of older people

PurposeTo investigate for socially isolated older people, and older people at risk of social isolation: (1) health status and health-related quality of life (HRQL); (2) the relationship between social isolation and health status/HRQL; (3) the relationship between two alternative measures of health status/HRQL.MethodsOlder people at risk of social isolation (n = 393) completed the EQ-5D and the SF-12. Multiple regression analyses were performed to examine the relationship between levels of social isolation and health status/HRQL, controlling for demographic/clinical characteristics. The agreement between EQ-5D and SF-6D (SF-12) scores was explored using descriptive psychometric techniques.ResultsHealth status and health state values were much lower than UK general population age-matched norms. After controlling for depression, physical co-morbidities, age, gender, living alone status, employment and accommodation, social isolation was significantly associated, to a degree that was clinically relevant, with EQ-5D DSI, SF-6D (SF-12) and SF-12 MCS scores. The potential for ceiling effects on the EQ-5D with this population was identified.ConclusionThis work highlights the burden that social isolation may have on the health and well-being of older people. The potential HRQL gains from addressing social isolation may be considerable, with those at risk of social isolation also a key target group.

Is volunteering a public health intervention? A systematic review and meta-analysis of the health and survival of volunteers

BackgroundVolunteering has been advocated by the United Nations, and American and European governments as a way to engage people in their local communities and improve social capital, with the potential for public health benefits such as improving wellbeing and decreasing health inequalities. Furthermore, the US Corporation for National and Community Service Strategic Plan for 2011–2015 focused on increasing the impact of national service on community needs, supporting volunteers’ wellbeing, and prioritising recruitment and engagement of underrepresented populations. The aims of this review were to examine the effect of formal volunteering on volunteers’ physical and mental health and survival, and to explore the influence of volunteering type and intensity on health outcomes.MethodsExperimental and cohort studies comparing the physical and mental health outcomes and mortality of a volunteering group to a non-volunteering group were identified from twelve electronic databases (Cochrane Library, Medline, Embase, PsychINFO, CINAHL, ERIC, HMIC, SSCI, ASSIA, Social Care Online, Social Policy and Practice) and citation tracking in January 2013. No language, country or date restrictions were applied. Data synthesis was based on vote counting and random effects meta-analysis of mortality risk ratios.ResultsForty papers were selected: five randomised controlled trials (RCTs, seven papers); four non-RCTs; and 17 cohort studies (29 papers). Cohort studies showed volunteering had favourable effects on depression, life satisfaction, wellbeing but not on physical health. These findings were not confirmed by experimental studies. Meta-analysis of five cohort studies found volunteers to be at lower risk of mortality (risk ratio: 0.78; 95% CI: 0.66, 0.90). There was insufficient evidence to demonstrate a consistent influence of volunteering type or intensity on outcomes.ConclusionObservational evidence suggested that volunteering may benefit mental health and survival although the causal mechanisms remain unclear. Consequently, there was limited robustly designed research to guide the development of volunteering as a public health promotion intervention. Future studies should explicitly map intervention design to clear health outcomes as well as use pragmatic RCT methodology to test effects.

An exercise intervention to prevent falls in people with Parkinson's disease: a pragmatic randomised controlled trial

Objectives To compare the effectiveness of an exercise programme with usual care in people with Parkinsons disease (PD) who have a history of falls. Design Pragmatic randomised controlled trial. Setting Recruitment was from three primary and four secondary care organisations, and PD support groups in South West England. The intervention was delivered in community settings. Participants People with PD, with a history of two or more falls in the previous year, who were able to mobilise independently. Intervention 10 week, physiotherapy led, group delivered strength and balance training programme with supplementary home exercises (intervention) or usual care (control). Main outcome measure Number of falls during the (a) 10 week intervention period and (b) the 10 week follow-up period. Results 130 people were recruited and randomised (64 to the intervention; 66 to usual care). Seven participants (5.4%) did not complete the study. The incidence rate ratio for falls was 0.68 (95% CI 0.43 to 1.07, p=0.10) during the intervention period and 0.74 (95% CI 0.41 to 1.33, p=0.31) during the follow-up period. Statistically significant between group differences were observed in Berg balance, Falls Efficacy Scale-International scores and recreational physical activity levels. Conclusions The study did not demonstrate a statistically significant between group difference in falls although the difference could be considered clinically significant. However, a type 2 error cannot be ruled out. The findings from this trial add to the evidence base for physiotherapy and exercise in the management of people with PD.

Use of the EuroQoL among elderly acute care patients

The assessment of the validity and reliability of generic quality of life (QoL) instruments among elderly patient groups has tended to lag behind such assessments in general populations, yet it is an important methodological issue. This paper presents the findings from a study of the use of the EuroQoL among an elderly acute care patient group, focusing particularly on the ability to self-complete, construct validity and sensitivity to change. Two hundred and fourteen UK patients aged 65 years and over, participating in a randomized controlled trial comparing hospital at home and routine hospital care were asked to complete the EuroQoL and a number of other instruments at randomization and at 4 week and 3 month follow-ups. The inability to self-complete the EuroQol was found to be strongly related to both increased age and reduced cognitive function (p < 0.0001). From logistic regression, the expected probability of an acute care patient requiring interview administration at age 65 years is 11%, at age 75 years is 37% and at age 85 years is 73%. The relationships with age and limiting long-standing illness/disability were weaker than expected, but the results obtained from the EuroQoL were highly correlated with those from both the Barthel index and the COOP-WONCA charts where this was anticipated. Preliminary evidence of sensitivity to change was found from descriptive statistics of the changes in scores for four specific subgroups of patients, but the small numbers and high variability in each sub-sample means that this should be interpreted with caution. The most important issue arising from the research concerns the impact of age on the ability to self-complete the EuroQoL questionnaire. It is argued that this research points to the need for rigorous studies (such as randomized controlled trials) to assess the impact of the format of administration of the EuroQoL on the scores obtained.

Telephone triage for management of same-day consultation requests in general practice (the ESTEEM trial): a cluster-randomised controlled trial and cost-consequence analysis.

BACKGROUND Telephone triage is increasingly used to manage workload in primary care; however, supporting evidence for this approach is scarce. We aimed to assess the effectiveness and cost consequences of general practitioner-(GP)-led and nurse-led telephone triage compared with usual care for patients seeking same-day consultations in primary care. METHODS We did a pragmatic, cluster-randomised controlled trial and economic evaluation between March 1, 2011, and March 31, 2013, at 42 practices in four centres in the UK. Practices were randomly assigned (1:1:1), via a computer-generated randomisation sequence minimised for geographical location, practice deprivation, and practice list size, to either GP-led triage, nurse-led computer-supported triage, or usual care. We included patients who telephoned the practice seeking a same-day face-to-face consultation with a GP. Allocations were concealed from practices until after they had agreed to participate and a stochastic element was included within the minimisation algorithm to maintain concealment. Patients, clinicians, and researchers were not masked to allocation, but practice assignment was concealed from the trial statistician. The primary outcome was primary care workload (patient contacts, including those attending accident and emergency departments) in the 28 days after the first same-day request. Analyses were by intention to treat and per protocol. This trial was registered with the ISRCTN register, number ISRCTN20687662. FINDINGS We randomly assigned 42 practices to GP triage (n=13), nurse triage (n=15), or usual care (n=14), and 20,990 patients (n=6695 vs 7012 vs 7283) were randomly assigned, of whom 16,211 (77%) patients provided primary outcome data (n=5171 vs 5468 vs 5572). GP triage was associated with a 33% increase in the mean number of contacts per person over 28 days compared with usual care (2·65 [SD 1·74] vs 1·91 [1·43]; rate ratio [RR] 1·33, 95% CI 1·30-1·36), and nurse triage with a 48% increase (2·81 [SD 1·68]; RR 1·48, 95% CI 1·44-1·52). Eight patients died within 7 days of the index request: five in the GP-triage group, two in the nurse-triage group, and one in the usual-care group; however, these deaths were not associated with the trial group or procedures. Although triage interventions were associated with increased contacts, estimated costs over 28 days were similar between all three groups (roughly £75 per patient). INTERPRETATION Introduction of telephone triage delivered by a GP or nurse was associated with an increase in the number of primary care contacts in the 28 days after a patients request for a same-day GP consultation, with similar costs to those of usual care. Telephone triage might be useful in aiding the delivery of primary care. The whole-system implications should be assessed when introduction of such a system is considered.
