Evidence based practice and its critics: what is a nurse manager to do?

Knowledge for Nursing Practice: Beyond Evidence Alone

OBJECTIVE

For the past 30 years there has been a growing emphasis on evidence as the primary or exclusive basis for nursing practice.

METHODS

Critical examination of literature related to evidence-based practice from the 1990s to the present.

RESULTS

This review of the nursing literature from the 1990s to the present reveals that in the midst of the movement to promote evidence-based practice as the gold standard, there have been persistent expressions of concern. These concerns are (a) lack of alignment of evidence-based practice with nursing's disciplinary perspective; (b) wrongful privileging of empirical knowledge over other sources of knowledge; (c) underappreciation of the complexity of practice and practice wisdom;(d) possibilities of evidence-based practice thwarting innovation and creativity;(e) vulnerabilities of empirical evidence to be flawed, inconsistent, and influenced by competing interests; (f) situational realities that limit access to and critical appraisal of evidence that access to and critical appraisal of evidence is not feasible or practical; and (g) lack of relationship of evidence-based practice to theory.

CONCLUSIONS

We call for a recalibrated practice epistemology that promotes a greater appreciation for the myriad sources of knowledge for nursing practice, and offer recommendations for international change in education, literature, scholarship, and public media.

Redeveloping the JBI Model of Evidence Based Healthcare

BACKGROUND

In 2005, Pearson et al. presented a developmental framework of evidence-based practice that sought to situate healthcare evidence and its role and use within the complexity of practice settings globally. A decade later, it was deemed timely to re-examine the Model and its component parts to determine whether they remain relevant and a true and accurate reflection of where the evidence-based movement is today.

METHODS

A two-phase process was employed for this project. Phase 1 involved a citation analysis, conducted using the index citation of the original source article on the Joanna Briggs Institute (JBI) Model by Pearson et al. The databases searched were Web of Science and Google Scholar from year of publication (2005) to July 2015. Duplicates and articles in languages other than English were removed, and all results were imported and combined in an Excel spreadsheet for review, coding and interpretation. Phase 2 (model revision) occurred in two parts. Part 1 involved revision of the Model by an internal working group. This revised version of the Model was then subjected to a process of focus group discussion (Part 2) that engaged staff of the Joanna Briggs Collaboration during the 2015 annual general meeting. These data were recorded then transcribed for review and consideration.

RESULTS

The citation analysis revealed that the Model was primarily utilized to conceptualize evidence and evidence-based healthcare, but that language used in relation to concepts within the Model was variable. Equally, the working group and focus group feedback confirmed that there was a need to ensure the language utilized in the Model was internationally appropriate and in line with current international trends. This feedback and analysis informed the revised version of the JBI Model.

CONCLUSION

Based on the citation analysis, working group and focus group feedback the new JBI Model for Evidence Based Healthcare attempts to utilize more internationally appropriate language to detail the intricacies of the relationships between systems and individuals across different settings and the need for contextual localization to enable policy makers and practitioners to make evidence-based decisions at the point of care.

How professional identity shapes youth healthcare

PURPOSE

The primary care sector is experiencing considerable change. How change and uncertainty are accommodated by the professional identity of medicine has not been examined. The purpose of this paper is to address the youth healthcare as an exemplar as this field is often a source of uncertainty for general practitioners (GPs).

DESIGN/METHODOLOGY/APPROACH

Using heterogeneity sampling, 22 GPs participated in focus groups to explore perceptions of youth healthcare, factors that help and hinder it, and training needs. Analysis of the research material was guided by a theoretical model on professional identity.

FINDINGS

GPs described tensions that challenged their professional identity - the challenges of working with young people and their complex issues, the extent to which youth healthcare sits within the purview of general practice, and the scope of training required. These tensions appeared to destabilise professional identity. Some participants had customised their identity by enriching understandings of and approach to general practice. Participants also reported work customisation as a way of managing the complex demands of the general practice role. Deepened insight appeared to bolster perceived capacity to support a complex patient cohort. Research limitations/implications - Participants are not representative of the primary care sector - furthermore, the methodology limits the generalisability of the findings.

PRACTICAL IMPLICATIONS

To bolster youth health, mere clinician training is insufficient. Youth health requires explicit support from governments and training providers to be incorporated into the healthcare landscape.

ORIGINALITY/VALUE

This study extends current research on professional identity by examining youth healthcare within the changing context of primary care.

The implausibility of 'usual care' in an open system: sedation and weaning practices in Paediatric Intensive Care Units (PICUs) in the United Kingdom (UK)

Background

The power of the randomised controlled trial depends upon its capacity to operate in a closed system whereby the intervention is the only causal force acting upon the experimental group and absent in the control group, permitting a valid assessment of intervention efficacy. Conversely, clinical arenas are open systems where factors relating to context, resources, interpretation and actions of individuals will affect implementation and effectiveness of interventions. Consequently, the comparator (usual care) can be difficult to define and variable in multi-centre trials. Hence outcomes cannot be understood without considering usual care and factors that may affect implementation and impact on the intervention.

Methods

Using a fieldwork approach, we describe PICU context, ‘usual’ practice in sedation and weaning from mechanical ventilation, and factors affecting implementation prior to designing a trial involving a sedation and ventilation weaning intervention. We collected data from 23 UK PICUs between June and November 2014 using observation, individual and multi-disciplinary group interviews with staff.

Results

Pain and sedation practices were broadly similar in terms of drug usage and assessment tools. Sedation protocols linking assessment to appropriate titration of sedatives and sedation holds were rarely used (9 % and 4 % of PICUs respectively). Ventilator weaning was primarily a medical-led process with 39 % of PICUs engaging senior nurses in the process: weaning protocols were rarely used (9 % of PICUs). Weaning methods were variably based on clinician preference. No formal criteria or use of spontaneous breathing trials were used to test weaning readiness. Seventeen PICUs (74 %) had prior engagement in multi-centre trials, but limited research nurse availability. Barriers to previous trial implementation were intervention complexity, lack of belief in the evidence and inadequate training. Facilitating factors were senior staff buy-in and dedicated research nurse provision.

Conclusions

We examined and identified contextual and organisational factors that may impact on the implementation of our intervention. We found usual practice relating to sedation, analgesia and ventilator weaning broadly similar, yet distinctively different from our proposed intervention, providing assurance in our ability to evaluate intervention effects. The data will enable us to develop an implementation plan; considering these factors we can more fully understand their impact on study outcomes.

Nurse managers' strategies for feeling less drained by their work: an action research and reflection project for developing emotional intelligence

AIMS

To raise nurse managers' critical awareness of practice problems; uncover practice constraints and improve work effectiveness.

BACKGROUND

Nurse management requires skills and knowledge, underscored by emotional intelligence. The research improved participants' practice and personal insights.

METHODS

Purposive sampling targeted nurse managers interested in improving their practice. Three experienced female nurse managers met fortnightly in a group, for 1 hour, for 10 meetings. The methods included: writing and sharing de-identified journal reflections; critically analysing practice stories; identifying a thematic concern; generating action strategies; and instituting and revising the action plan.

RESULTS

Phase One resulted in the identification of the issue of 'being drained by the intensity of nurse managers' work'. The participants adopted five strategies: debriefing problematic situations; deflecting multiple requests; diffusing issues; naming dysfunctional behaviours; and regrouping. In Phase Two, participants implemented and revised the action plan strategies, which resulted in them feeling less drained by their work.

CONCLUSIONS

Strategies can lessen nurse managers' sense of personal depletion. However, strategies cannot guarantee success every time because the emotional intelligence is integral to nurse management.

IMPLICATIONS FOR NURSING MANAGEMENT

Action research and reflection assist nurse managers to improve their practice and develop their emotional intelligence.

Does individual placement and support really 'reflect client goals'?

Individual placement and support (IPS) is considered the only evidence-based practice available for providing vocational support within secondary mental health services. Clients are supported into and during competitive employment, with proponents claiming IPS 'reflects client goals' because most service users want to work. The idea that work improves mental health is also involved in promoting IPS in the U.K. This paper examines the evidential basis for these claims in policy documents and cited research. It additionally draws upon qualitative research in representing the value, meaning and challenges of working described by service users, while briefly considering the U.K. socio-economic context for IPS implementation. Statistical claims that most unemployed service users want to work are found misleadingly applied to IPS because only a minority say they want competitive employment. Discussion centres on the power interests such statistics serve and their role in underpinning the relevance of IPS randomized control trials. Assertions that work improves mental health are found confusing as a result of use of a dual continua model of mental illness and mental health. The internalized moral basis for work acting as a seemingly healthy 'normalization' experience is suggested as paradoxically feeding self-stigma in those who feel they cannot work.
