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.     

Conjunctival T-cell subpopulations in Sjögren's and non-Sjögren's patients with dry eye

PURPOSE: To examine the conjunctiva of patients with Sj?gren's syndrome keratoconjunctivitis sicca (SS-KCS) and non-Sj?gren's keratoconjunctivitis sicca (NS-KCS) for evidence of immune-based inflammation. METHODS: Conjunctival biopsy specimens were obtained from 15 patients with SS-KCS and 15 with NS-KCS. Immunohistochemistry was performed on frozen sections to characterize and quantify T-cell subtypes (CD3, CD4, and CD8) and markers of immune activation (major histocompatibility complex [MHC] class II: HLA-DR, HLA-DQ) and inflammation (intercellular adhesion molecule [ICAM]-1). The numbers of cells positive for each marker were counted by two masked observers and averaged. RESULTS: Conjunctival biopsy specimens from patients with SS-KCS or NS-KCS revealed lymphocytic infiltration and increased immunoreactivity for the markers of inflammation and immune activation. The extent of cellular immunoreactivity did not differ significantly between SS-KCS and NS-KCS tissue samples. CONCLUSIONS: The authors' findings indicate that patients with SS-KCS or NS-KCS have conjunctival inflammation manifested by inflammatory cell infiltrates and upregulation of expression in markers of immune activation. Clinical symptoms of KCS may be more dependent on T-cell activation and resultant inflammation than previously believed. In addition to tear substitutes, anti-inflammatory therapeutics should be investigated for the treatment of KCS.     

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.     

Phenotypic variation and detection of carrier status in the partial androgen insensitivity syndrome

The partial androgen insensitivity syndrome occurs in 46,XY subjects with phenotypes ranging from perineoscrotal hypospadias with cryptorchidism and micropenis (mild undervirilisation) to clitoromegaly and partial labial fusion (marked undervirilisation). Within an affected family, wide variation in the degree of genital ambiguity between individuals can be seen. Two cousins of a previously reported subject who had severe genital ambiguity and partial androgen insensitivity were investigated. Neither of the cousins had genital abnormalities as marked as the index case, who also had qualitatively abnormal androgen binding and two mutations of the androgen receptor gene. Despite marked phenotypic differences between the index case and his cousins, similar androgen binding and the same androgen receptor mutations were shown in the cousins. Furthermore, one of the androgen receptor gene mutations has been shown in the mother and sister of one of the boys indicating that they are carriers. Thus phenotypic variation in families affected by partial androgen insensitivity is dependent on factors other than abnormalities of the androgen receptor gene alone. Although carrier status in partial androgen insensitivity can be determined, the severity of genital abnormalities in an affected offspring cannot be reliably predicted.
