There is debate on how the methodological quality of clinical trials should be assessed. We compared trials of physical therapy (PT) judged to be of adequate quality based on summary scores from the ...Physiotherapy Evidence Database (PEDro) scale with trials judged to be of adequate quality by Cochrane Risk of Bias criteria.
Meta-epidemiological study within Cochrane Database of Systematic Reviews.
Meta-analyses of PT trials were identified in the Cochrane Database of Systematic Reviews. For each trial PeDro and Cochrane assessments were extracted from the PeDro and Cochrane databases. Adequate quality was defined as adequate generation of random sequence, concealment of allocation, and blinding of outcome assessors (Cochrane criteria) or as trials with a PEDro summary score ≥5 or ≥6 points. We combined trials of adequate quality using random-effects meta-analysis.
Forty-one Cochrane reviews and 353 PT trials were included. All meta-analyses included trials with PEDro scores ≥5, 37 (90.2%) included trials with PEDro scores ≥6 and only 22 (53.7%) meta-analyses included trials of adequate quality according to the Cochrane criteria. Agreement between PeDro and Cochrane was poor for PeDro scores of ≥5 points (kappa = 0.12; 95% CI 0.07 to 0.16) and slight for ≥6 points (kappa 0.24; 95% CI 0.16-0.32). When combining effect sizes of trials deemed to be of adequate quality according to PEDro or Cochrane criteria, we found that a substantial difference in the combined effect size (≥0.15) was evident in 9 (22%) out of the 41 meta-analyses for PEDro cutoff ≥5 and 10 (24%) for cutoff ≥6.
The PeDro and Cochrane approaches lead to different sets of trials of adequate quality, and different combined treatment estimates from meta-analyses of these trials. A consistent approach to assessing RoB in trials of physical therapy should be adopted.

Abstract
The compact muon solenoid experiment phase 1 hadron calorimeter upgrade implemented the first large-scale application of VTRx modules, radiation and magnetic field tolerant optical ...transceivers. During run 2 of the Large Hadron Collider, the CMS hadron calorimeter endcap experienced a failure of control communication that revealed a variable manufacturing weakness in the VTRx and affected nearly half of the communication links in the hadron calorimeter endcaps. The CMS hadron calorimeter team provided the first observation of this phenomenon, linked the loss to the VTRx, revealed its temperature dependence, and pioneered the mitigation tactic adopted by other LHC experiments. Aspects of the CMS hadron calorimeter team’s role in the larger VTRx investigations are presented.
To estimate the annual, per-patient incremental burden of diabetic foot ulcers (DFUs).
DFU patients and non-DFU patients with diabetes (controls) were selected using two de-identified databases: ages ...65+ years from a 5% random sample of Medicare beneficiaries (Standard Analytical Files, January 2007-December 2010) and ages 18-64 years from a privately insured population (OptumInsight, January 2007-September 2011). Demographics, comorbidities, resource use, and costs from the payer perspective incurred during the 12 months prior to a DFU episode were identified. DFU patients were matched to controls with similar pre-DFU characteristics using a propensity score methodology. Per-patient incremental clinical outcomes (e.g., amputation and medical resource utilization) and health care costs (2012 U.S. dollars) during the 12-month follow-up period were measured among the matched cohorts.
Data for 27,878 matched pairs of Medicare and 4,536 matched pairs of privately insured patients were analyzed. During the 12-month follow-up period, DFU patients had more days hospitalized (+138.2% Medicare, +173.5% private), days requiring home health care (+85.4% Medicare, +230.0% private), emergency department visits (+40.6% Medicare, +109.0% private), and outpatient/physician office visits (+35.1% Medicare, +42.5% private) than matched controls. Among matched patients, 3.8% of Medicare and 5.0% of privately insured DFU patients received lower limb amputations. Increased utilization resulted in DFU patients having $11,710 in incremental annual health care costs for Medicare, and $16,883 for private insurance, compared with matched controls. Privately insured matched DFU patients incurred excess work-loss costs of $3,259.
These findings document that DFU imposes substantial burden on public and private payers, ranging from $9-13 billion in addition to the costs associated with diabetes itself.
Aims and objectives
To appraise and synthesise empirical studies examining sources of occupational stress and ways of coping utilised by nurse managers when dealing with stress.
Background
The Nurse ...Manager's role is challenging yet draining and stressful and has adverse consequences on an individual's overall health and well‐being, patients’ outcomes and organisational productivity. Considerable research has been carried out; however, an updated and broader perspective on this critical organisational issue has not been performed.
Design
An integrative review.
Methods
Five databases (Cumulative Index to Nursing and Allied Health Literature, SCOPUS, PubMed, PsychINFO and MEDLINE) were searched to identify relevant articles. Search terms and MeSH terms included: “charge nurse,” “coping,” “coping strategy,” “coping style,” “psychological adaptation,” “psychological stress,” “stressors,” “nurse manager” and “unit manager.” Twenty‐two articles were included in this review. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses statement guidelines.
Results
Four themes were identified: moderate stress levels, common sources of stress, ways of coping and the impact of nurses’ characteristics on stress.
Conclusions
Nurse managers experienced moderate levels of stress mainly from heavy workloads, lack of resources and financial responsibilities. Enhancing social support and promoting job control were seen as important in reducing work stress and its related consequences. Additional studies using a more rigorous method and a larger sample size preferably in multicultural settings would shed more light on this topic.
Relevance to clinical practice
Hospital and nurse administrators play an important role in promoting supportive structures for daily professional practice for nurse managers through staffing, organisational resources, support services, leadership and stress management training.
Numerous policy and research reports call for leadership to build quality work environments, implement new models of care, and bring health and wellbeing to an exhausted and stretched nursing ...workforce. Rarely do they indicate how leadership should be enacted, or examine whether some forms of leadership may lead to negative outcomes. We aimed to examine the relationships between various styles of leadership and outcomes for the nursing workforce and their work environments.
The search strategy of this multidisciplinary systematic review included 10 electronic databases. Published, quantitative studies that examined leadership behaviours and outcomes for nurses and organizations were included. Quality assessments, data extractions and analysis were completed on all included studies.
34,664 titles and abstracts were screened resulting in 53 included studies. Using content analysis, 64 outcomes were grouped into five categories:
staff
satisfaction with work,
role and pay,
staff relationships with work,
staff health and wellbeing,
work environment factors, and
productivity and effectiveness. Distinctive patterns between relational and task focused leadership styles and their outcomes for nurses and their work environments emerged from our analysis. For example, 24 studies reported that leadership styles focused on people and relationships (transformational, resonant, supportive, and consideration) were associated with higher nurse job satisfaction, whereas 10 studies found that leadership styles focused on tasks (dissonant, instrumental and management by exception) were associated with lower nurse job satisfaction. Similar trends were found for each category of outcomes.
Our results document evidence of various forms of leadership and their differential effects on the nursing workforce and work environments. Leadership focused on task completion alone is not sufficient to achieve optimum outcomes for the nursing workforce. Efforts by organizations and individuals to encourage and develop transformational and relational leadership are needed to enhance nurse satisfaction, recruitment, retention, and healthy work environments, particularly in this current and worsening nursing shortage.
The purpose of this paper is to present findings of an integrative literature review related to emotional intelligence (EI) and nursing.
A large body of knowledge related to EI exists outside ...nursing. EI theory and research within nursing is a more recent phenomenon. A broad understanding of the nature and direction of theory and research related to EI is crucial to building knowledge within this field of inquiry.
A broad search of computerized databases focusing on articles published in English during 1995–2007 was completed. Extensive screening sought to determine current literature themes and empirical research evidence completed in nursing focused specifically on emotional intelligence.
39 articles are included in this integrative literature review (theoretical,
n
=
21; editorial,
n
=
5; opinion,
n
=
4 and empirical,
n
=
9). The literature focuses on EI and nursing education, EI and nursing practice, EI and clinical decision-making, and EI and clinical leadership. Research that links EI and nursing are mostly correlation designs using small sample sizes.
This literature reveals widespread support of EI concepts in nursing. Theoretical and editorial literature confirms EI concepts are central to nursing practice. EI needs to be explicit within nursing education as EI might impact the quality of student learning, ethical decision-making, critical thinking, evidence and knowledge use in practice. Emotionally intelligent leaders influence employee retention, quality of patient care and patient outcomes. EI research in nursing requires development and careful consideration of criticisms related to EI outside nursing is recommended.
brady germain p. & cummings g.g. (2010) Journal of Nursing Management18, 425–439 The influence of nursing leadership on nurse performance: a systematic literature review
Aim The aim was to explore ...leadership factors that influence nurse performance and particularly, the role that nursing leadership behaviors play in nurses’ perceptions of performance motivation.
Background Nurse performance is vital to quality patient care outcomes and nursing leadership behaviors have been linked to nurse performance.
Evaluations A review of research articles that examined the factors that nurses perceived as influencing their motivation and performance was conducted. Eight studies were included in the final analysis.
Key issues Nurses’ perceptions of factors that affect their motivation and ability to perform were grouped into five categories using content analysis: autonomy, work relationships, resource accessibility, nurse factors, and leadership practices. Nursing leadership behaviors were found to influence both nurses’ motivations directly and indirectly via other factors.
Conclusion The review suggests that nurse performance may be improved by addressing nurse autonomy, relationships among nurses, their colleagues and leaders, and resource accessibility.
Implications for nursing management Nursing managers and leaders may enhance their nurses’ performance by understanding and addressing the factors that affect their ability and motivation to perform.
Aim The purpose of this review was to describe findings of a systematic review of studies that examine the relationship between nursing leadership and patient outcomes.
Background With recent ...attention directed to the creation of safer practice environments for patients, nursing leadership is called on to advance this agenda within organizations. However, surprisingly little is known about the actual association between nursing leadership and patient outcomes.
Methods Published English‐only research articles that examined formal nursing leadership and patient outcomes were selected from computerized databases and manual searches. Data extraction and methodological quality assessment were completed for the final seven quantitative research articles.
Results Evidence of significant associations between positive leadership behaviours, styles or practices and increased patient satisfaction and reduced adverse events were found. Findings relating leadership to patient mortality rates were inconclusive.
Conclusion The findings of this review suggest that an emphasis on developing transformational nursing leadership is an important organizational strategy to improve patient outcomes.
Recent methodologic evidence suggests that lack of blinding in randomized trials can result in under- or overestimation of the treatment effect size. The objective of this study is to quantify the ...extent of bias associated with blinding in randomized controlled trials of oral health interventions.
We selected all oral health meta-analyses that included a minimum of five randomized controlled trials. We extracted data, in duplicate, related to nine blinding-related criteria, namely: patient blinding, assessor blinding, care-provider blinding, investigator blinding, statistician blinding, blinding of both patients and assessors, study described as "double blind", blinding of patients, assessors, and care providers concurrently, and the appropriateness of blinding. We quantified the impact of bias associated with blinding on the magnitude of effect size using a two-level meta-meta-analytic approach with a random effects model to allow for intra- and inter-meta-analysis heterogeneity.
We identified 540 randomized controlled trials, included in 64 meta-analyses, analyzing data from 137,957 patients. We identified significantly larger treatment effect size estimates in trials that had inadequate patient blinding (difference in treatment effect size = 0.12; 95% CI: 0.00 to 0.23), lack of blinding of both patients and assessors (difference = 0.19; 95% CI: 0.06 to 0.32), and lack of blinding of patients, assessors, and care-providers concurrently (difference = 0.14; 95% CI: 0.03 to 0.25). In contrast, assessor blinding (difference = 0.06; 95% CI: -0.06 to 0.18), caregiver blinding (difference = 0.02; 95% CI: -0.04 to 0.09), principal-investigator blinding (difference = - 0.02; 95% CI: -0.10 to 0.06), describing a trial as "double-blind" (difference = 0.09; 95% CI: -0.05 to 0.22), and lack of an appropriate method of blinding (difference = 0.06; 95% CI: -0.06 to 0.18) were not associated with over- or underestimated treatment effect size.
We found significant differences in treatment effect size estimates between oral health trials based on lack of patient and assessor blinding. Treatment effect size estimates were 0.19 and 0.14 larger in trials with lack of blinding of both patients and assessors and blinding of patients, assessors, and care-providers concurrently. No significant differences were identified in other blinding criteria. Investigators of oral health systematic reviews should perform sensitivity analyses based on the adequacy of blinding in included trials.

To examine the risks of bias, risks of random errors, reporting quality, and methodological quality of randomized clinical trials of oral health interventions and the development of these aspects ...over time.
We included 540 randomized clinical trials from 64 selected systematic reviews. We extracted, in duplicate, details from each of the selected randomized clinical trials with respect to publication and trial characteristics, reporting and methodologic characteristics, and Cochrane risk of bias domains. We analyzed data using logistic regression and Chi-square statistics.
Sequence generation was assessed to be inadequate (at unclear or high risk of bias) in 68% (n = 367) of the trials, while allocation concealment was inadequate in the majority of trials (n = 464; 85.9%). Blinding of participants and blinding of the outcome assessment were judged to be inadequate in 28.5% (n = 154) and 40.5% (n = 219) of the trials, respectively. A sample size calculation before the initiation of the study was not performed/reported in 79.1% (n = 427) of the trials, while the sample size was assessed as adequate in only 17.6% (n = 95) of the trials. Two thirds of the trials were not described as double blinded (n = 358; 66.3%), while the method of blinding was appropriate in 53% (n = 286) of the trials. We identified a significant decrease over time (1955-2013) in the proportion of trials assessed as having inadequately addressed methodological quality items (P < 0.05) in 30 out of the 40 quality criteria, or as being inadequate (at high or unclear risk of bias) in five domains of the Cochrane risk of bias tool: sequence generation, allocation concealment, incomplete outcome data, other sources of bias, and overall risk of bias.
The risks of bias, risks of random errors, reporting quality, and methodological quality of randomized clinical trials of oral health interventions have improved over time; however, further efforts that contribute to the development of more stringent methodology and detailed reporting of trials are still needed.
