The relationship between structural empowerment and psychological empowerment for nurses: a systematic review Aim To describe the findings of a systematic review examining the relationship between structural empowerment and psychological empowerment for registered nurses (RNs). Background Workplace empowerment research reveals a link between empowerment and positive work behaviours and attitudes. Research demonstrating the essential relationship between structural empowerment and psychological empowerment will provide direction for future interventions aimed at the development of a strong and effective health care sector. Methods Published research articles examining structural empowerment and psychological empowerment for nurses were selected from computerized databases and selected websites. Data extraction and methodological quality assessment were completed for the included research articles. Results Ten papers representing six studies reveal significant associations between structural empowerment and psychological empowerment for RNs. Implications for nursing management Creation of an environment that provides structural empowerment is an important organizational strategy that contributes to RNs’ psychological empowerment and ultimately leads to positive work behaviours and attitudes. Critical structural components of an empowered workplace can contribute to a healthy, productive and innovative RN workforce with increased job satisfaction and retention.     

The influence of nursing leadership on nurse performance: a systematic literature review

brady germain p. & cummings g.g. (2010) Journal of Nursing Management 18, 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.     

Predictors of nurse absenteeism in hospitals: a systematic review

Aim  This study aimed to identify and examine predictors of short-term absences of staff nurses working in hospital settings reported in the research literature.
Background  Front-line staff nurse absenteeism contributes to discontinuity of patient care, decreased staff morale and is costly to healthcare.
Evaluation  A systematic review of studies from 1986 to 2006, obtained through electronic searches of 10 online databases led to inclusion of 16 peer-reviewed research articles. Seventy potential predictors of absenteeism were examined and analysed using content analysis.
Key issue  Our findings showed that individual 'nurses' prior attendance records', 'work attitudes' (job satisfaction, organizational commitment and work/job involvement) and 'retention factors' reduced nurse absenteeism, whereas 'burnout' and 'job stress' increased absenteeism. Remaining factors examined in the literature did not significantly predict nurse absenteeism.
Conclusions  Reasons underlying absenteeism among staff nurses are still poorly understood. Lack of robust theory about nursing absenteeism may underlie the inconsistent results found in this review. Further theory development and research is required to explore the determinants of short-term absenteeism of nurses in acute care hospitals.
Implications for nursing management  Work environment factors that increase nurses' job satisfaction, and reduce burnout and job stress need to be considered in managing staff nurse absenteeism.     

Early cognitive decline in Creutzfeldt-Jakob disease associated with human growth hormone treatment

BACKGROUND: Most cases of Creutzfeldt-Jakob disease (CJD) in recipients of human cadaveric growth hormone present with a cerebellar syndrome. Dementia is thought to occur late and as a minor feature of the illness. However, neuropsychology data published on these cases are largely qualitative and anecdotal. The first published case does include a neuropsychological assessment seven months after the onset of a cerebellar syndrome, showing evidence of intellectual decline. Subsequent reports hint that cognitive problems may be present in the initial stages of the illness. OBJECTIVE: To assess early cognition in Creutzfeldt-Jakob disease in recipients of pituitary derived human growth hormone. METHODS: Detailed neuropsychology assessment is reported at referral (mean 4.5 months from the onset of symptoms; range 4 to 6 months) in five patients with histologically proven human growth hormone derived CJD. RESULTS: All cases presented with a cerebellar syndrome and only one had noticed mild memory problems. On formal testing, however, four had demonstrable mild intellectual decline, as measured on the WAIS-R. One case showed selective visual memory impairment and frontal executive dysfunction. CONCLUSIONS: These findings suggest that, although not the presenting feature, mild cognitive decline may be evident in the early stages of CJD associated with human cadaveric growth hormone treatment.     

National survey to assess current practices in the diagnosis and management of young people with dementia

BACKGROUND: The Royal College of Psychiatrists has recommended that old age psychiatrists may be best placed to take responsibility for service provision for younger people with dementia. There are concerns however, that if referral between specialists, particularly neurologists and old age psychiatrists, is incomplete, patients may be under investigated or inappropriately followed up. OBJECTIVES: We have assessed the current level of referral between these specialists, how each investigates their patients and details of follow up care. METHOD: We conducted a postal survey of all consultant neurologists and consultant old age psychiatrists in the UK with an overall response rate of 64%. RESULTS and CONCLUSIONS: The ideal of full collaboration between old age psychiatrists and neurologists is not achieved. Young patients may be under investigated if managed solely by an old age psychiatrist and may not receive adequate follow up services if managed solely by a neurologist.     

Availability of Diagnostic and Treatment Services for Acute Stroke in Frontier Counties in Montana and Northern Wyoming

CONTEXT: Rapid diagnosis and treatment of ischemic stroke can lead to improved patient outcomes. Hospitals in rural and frontier counties, however, face unique challenges in providing diagnostic and treatment services for acute stroke. PURPOSE: The aim of this study was to assess the availability of key diagnostic technology and programs for acute stroke evaluation and treatment in Montana and northern Wyoming. METHODS: In 2004, hospital medical directors or their designees were mailed a survey about the availability of diagnostic technology, programs, and personnel for acute stroke care. FINDINGS: Fifty-eight of 67 (87%) hospitals responded to the survey. Seventy-nine percent (46/58) of responding hospitals were located in frontier counties, with an average bed size of 18 (11 SD). Of the hospitals in frontier counties, 44% reported emergency medical services prehospital stroke identification programs, 39% had 24-hour computed tomography capability, 44% had an emergency department stroke protocol, and 61% had a recombinant tissue plasminogen activator protocol. Thirty percent of hospitals in frontier counties reported that they met 6-10 of the criteria established by the Brain Attack Coalition to improve acute stroke care compared to 67% of hospitals in the nonfrontier counties. CONCLUSION: A stroke network model could enhance care and improve outcomes for stroke victims in frontier counties.     

Critical realism as emancipatory action: the case for realistic evaluation in practice development

Abstract  To provide rigour when preparing a research design, the researcher needs to carefully consider not only the methodology but also the philosophical intent of the study. This, however, is often absent from reported research and provides the reader with little evidence by which to judge the merits of the chosen methodology and its influence on the study. The purpose of this paper is to set out the case for critical realism as a framework to guide appropriate action in practice development and realistic evaluation for understanding the consequences of those actions.
It is evident that critical realism and critical social science share common ground. Emancipatory practice development (ePD) is based on the philosophy of critical social science and therefore by virtue is linked to the tenets of critical realism. Until now, the evaluation of ePD programme has been well served by 4th-generation evaluation. However, this paper outlines the need for a different approach to evaluation, one that is based on critical realism, that is concerned with emancipation, and that can be used in the ever-changing environment of clinical practice. Realistic evaluation not only links strongly to ePD programmes, but also serves as the basis for effective research questions that will test the outcomes of the research and inform the transferability of ePD mechanisms into differing contexts.     

A novel tau mutation (N296N) in familial dementia with swollen achromatic neurons and corticobasal inclusion bodies

Familial dementia with swollen achromatic neurons and corticobasal inclusion bodies is a neurodegenerative disease that resembles corticobasal degeneration. It is characterized by the presence of abundant neuronal and glial tau protein deposits. Here we describe a novel silent mutation in exon 10 of tau (N296N) in this familial dementia. By exon trapping, the mutation produced an increase in the splicing in of exon 10, indicating that it probably causes disease through an overproduction of four-repeat tau.
