A comparison of the nursing practice environment in mental health and medical-surgical settings

Purpose: To examine the differences between characteristics of the work environment of nurses working in mental health and general acute inpatient nursing settings.Design: Secondary analysis of data collected on 96 randomly selected medical and surgical (general) wards and six mental health wards in 24 public acute general hospitals across two Australian states between 2004 and 2006.Methods: All nurses on the participating wards were asked to complete a survey that included the Practice Environment Scale of the Nursing Work Index (NWI-PES). Responses were received from 2,556 nurses (76.3% response rate). Using the five-domain structure, comparisons were made between mental health and general nurses.Findings: Across the entire sample of nurses, those working in mental health settings scored more highly in regard to nurse-doctor relationships and staffing adequacy. Nurses in general wards reported more participation in hospital affairs, stronger leadership, and the presence of more of the foundations of nursing quality care such as access to continued education. Differences between the groups on each of the domains was statistically significant at p=05 or greater, but not for the composite practice environment scale. A wide range of responses was seen when data were aggregated to the ward level.Conclusions: The work environment of mental health nurses is different from that of their colleagues working in general settings. Specific areas of the mental health environment, such as participation in the hospital, leadership, and the foundations of quality, may be enhanced to improve nurses' job satisfaction and, potentially, other nurse and patient outcomes.Clinical Relevance: Factors in the medical and surgical nursing practice environment have been established as significant influences on nurse and patient outcomes. It is important to understand the existence and potential impact of these factors in mental health inpatient settings. © 2010 Sigma Theta Tau International

Patient transfers in Australia: Implications for nursing workload and patient outcomes

Aim To discuss the impact of patient transfers on patient outcomes and nursing workload. Background Many patient transfers are essential and occur in response to patients' clinical changes. However, increasingly within Australia transfers are performed in response to reductions in bed numbers, resulting in 'bed block'. Evaluation A discussion of the literature related to inpatient transfers, nursing workload and patient safety. Key issues Measures to increase patient flow such as short-stay units may result in an increase in patient transfers and nursing workload. Frequent patient transfers may also increase the risk of medication incidents, health-care acquired infections and patient falls. Conclusions The continuing demand for health care has led to a reactionary bed management system that, in an attempt to accommodate patients, has resulted in increased transfers between wards. This can have a negative effect on nursing workload and affect patient outcomes. Implications for nursing management High nursing workload is cited as one reason for nurses leaving the profession. Reductions in non-essential transfers may reduce nurse workload, improve patient outcomes and enhance continuity of patient care. © 2011 Blackwell Publishing Ltd

The rate and cost of nurse turnover in Australia

© 2014 Australian College of Nursing Ltd. Nurse turnover is a critical issue facing workforce planners across the globe, particularly in light of protracted and continuing workforce shortages. An ageing population coupled with the rise in complex and chronic diseases, have contributed to increased demands placed on the health system and importantly, nurses who themselves are ageing. Costs associated with nurse turnover are attracting more attention; however, existing measurements of turnover show inconsistent findings, which can be attributed to differences in study design, metrics used to calculate turnover and variations in definitions for turnover. This paper will report the rates and costs of nurse turnover across three States in Australia

Instability in patient and nurse characteristics, unit complexity and patient and system outcomes

© 2014 John Wiley & Sons Ltd. Aims: To explore key factors related to nursing unit instability, complexity and patient and system outcomes. Background: The relationship between nurse staffing and quality of patient outcomes is well known. The nursing unit is an important but different aspect that links to complexity and to system and patient outcomes. The relationship between the instability, complexity and outcomes needs further exploration. Design: Descriptive. Methods: Data were collected via a nurse survey, unit profile and review of patient records on 62 nursing units (wards) across three states of Australia between 2008-2010. Two units with contrasting levels of patient and nurse instability and negative system and patient outcomes, were profiled in detail from the larger sample. Results: Ward A presented with greater patient stability (low occupancy, high planned admissions, few ICU transfers, fewer changes to patient acuity/work re-sequencing) and greater nurse instability (nurses changing units, fewer full-time staff, more temporary/casual staff) impacting system outcomes negatively (high staff turnover). In contrast, Ward B had greater patient instability, however, more nurse stability (greater experienced and permanent staff, fewer casuals), resulting in high rates for falls, medication errors and other adverse patient outcomes with lower rates for system outcomes (lower intention to leave). Conclusion: Instability in patient and nurse factors can contribute to ward complexity with potentially negative patient outcomes. The findings highlight the variation of many aspects of the system where nurses work and the importance of nursing unit managers and senior nurse executives in managing ward complexity

Changes in nurses’ work associated with computerised information systems: Opportunities for international comparative studies using the revised Work Observation Method by Activity Timing (WOMBAT)

An important step in advancing global health through informatics is to understand how systems support health professionals to deliver improved services to patients. Studies in several countries have highlighted the potential for clinical information systems to change patterns of work and communication, and in particular have raised concerns that they reduce nurses’ time in direct care. However measuring the effects of systems on work is challenging and comparisons across studies have been hindered by a lack of standardised definitions and measurement tools. This paper describes the Work Observation Method by Activity Time (WOMBAT) technique version 1.0 and the ways in which the data generated can describe different aspects of health professionals’ work. In 2011 a revised WOMBAT version 2.0 was developed specifically to facilitate its use by research teams in different countries. The new features provide opportunities for international comparative studies of nurses’ work to be conducted

The Use of Unregulated Staff: Time for Regulation?

Internationally, shortages in the nursing workforce, escalating patient demands, and financial constraints within the health system have led to the growth of unlicensed nursing support workers. Recently, in relation to the largest publicly funded health system (National Health Service), it was reported that extensive substitution of registered nurses with unskilled nursing support workers resulted in inadequate patient care, increased morbidity and mortality rates, and negative nurse outcomes. We argue that it is timely to consider regulation of nursing support workers with their role and scope of practice clearly defined. Further, the addition of these workers in a complementary model of care (rather than substitutive model) should also be explored in future research, in terms of impact on patient and nurse outcomes. © The Author(s) 2014 Reprints and permissions:]br]sagepub.co.uk/journalsPermissions.nav

The influence of refuge sharing on social behaviour in the lizard Tiliqua rugosa

Refuge sharing by otherwise solitary individuals during periods of inactivity is an integral part of social behaviour and has been suggested to be the precursor to more complex social behaviour. We compared social association patterns of active versus inactive sheltering individuals in the social Australian sleepy lizard, Tiliqua rugosa, to empirically test the hypothesis that refuge sharing facilitates social associations while individuals are active. We fitted 18 neighbouring lizards with Global Positioning System (GPS) recorders to continuously monitor social associations among all individuals, based on location records taken every 10 min for 3 months. Based on these spatial data, we constructed three weighted, undirected social networks. Two networks were based on empirical association data (one for active and one for inactive lizards in their refuges), and a third null model network was based on hypothetical random refuge sharing. We found patterns opposite to the predictions of our hypothesis. Most importantly, association strength was higher in active than in inactive sheltering lizards. That is, individual lizards were more likely to associate with other lizards while active than while inactive and in shelters. Thus, refuge sharing did not lead to increased frequencies of social associations while lizards were active, and we did not find any evidence that refuge sharing was a precursor to sleepy lizard social behaviour. Our study of an unusually social reptile provides both quantitative data on the relationship between refuge sharing and social associations during periods of activity and further insights into the evolution of social behaviour in vertebrates

Paramedic clinical decision making during high acuity emergency calls: design and methodology of a Delphi study

<p>Abstract</p> <p>Background</p> <p>The scope of practice of paramedics in Canada has steadily evolved to include increasingly complex interventions in the prehospital setting, which likely have repercussions on clinical outcome and patient safety. Clinical decision making has been evaluated in several health professions, but there is a paucity of work in this area on paramedics. This study will utilize the Delphi technique to establish consensus on the most important instances of paramedic clinical decision making during high acuity emergency calls, as they relate to clinical outcome and patient safety.</p> <p>Methods and design</p> <p>Participants in this multi-round survey study will be paramedic leaders and emergency medical services medical directors/physicians from across Canada. In the first round, participants will identify instances of clinical decision making they feel are important for patient outcome and safety. On the second round, the panel will rank each instance of clinical decision making in terms of its importance. On the third and potentially fourth round, participants will have the opportunity to revise the ranking they assigned to each instance of clinical decision making. Consensus will be considered achieved for the most important instances if 80% of the panel ranks it as important or extremely important. The most important instances of clinical decision making will be plotted on a process analysis map.</p> <p>Discussion</p> <p>The process analysis map that results from this Delphi study will enable the gaps in research, knowledge and practice to be identified.</p

Conserved Expression of the Glutamate NMDA Receptor 1 Subunit Splice Variants during the Development of the Siberian Hamster Suprachiasmatic Nucleus

Glutamate neurotransmission and the N-methyl-D-aspartate receptor (NMDAR) are central to photic signaling to the master circadian pacemaker located in the hypothalamic suprachiasmatic nucleus (SCN). NMDARs also play important roles in brain development including visual input circuits. The functional NMDAR is comprised of multiple subunits, but each requiring the NR1 subunit for normal activity. The NR1 can be alternatively spliced to produce isoforms that confer different functional properties on the NMDAR. The SCN undergoes extensive developmental changes during postnatal life, including synaptogenesis and acquisition of photic signaling. These changes are especially important in the highly photoperiodic Siberian hamster, in which development of sensitivity to photic cues within the SCN could impact early physiological programming. In this study we examined the expression of NR1 isoforms in the hamster at different developmental ages. Gene expression in the forebrain was quantified by in situ hybridization using oligonucleotide probes specific to alternatively spliced regions of the NR1 heteronuclear mRNA, including examination of anterior hypothalamus, piriform cortex, caudate-putamen, thalamus and hippocampus. Gene expression analysis within the SCN revealed the absence of the N1 cassette, the presence of the C2 cassette alone and the combined absence of C1 and C2 cassettes, indicating that the dominant splice variants are NR1-2a and NR1-4a. Whilst we observe changes at different developmental ages in levels of NR1 isoform probe hybridization in various forebrain structures, we find no significant changes within the SCN. This suggests that a switch in NR1 isoform does not underlie or is not produced by developmental changes within the hamster SCN. Consistency of the NR1 isoforms would ensure that the response of the SCN cells to photic signals remains stable throughout life, an important aspect of the function of the SCN as a responder to environmental changes in quality/quantity of light over the circadian day and annual cycle
