A comparison of the work of qualified nurses and nursing auxiliaries in primary, team and functional nursing wards

PhD ThesisDespite the large scale utilisation of nursing auxiliaries (NAs) within the health service, there is a paucity of research evaluating their effectiveness. This study aimed to compare the contribution to patient care of NAs with that of qualified nurses (QNs) using a qualitative indicator, nurse-patient verbal interaction. Different grades were also compared in terms of activities performed and perceptions of their work environment. The organisation of nursing work also has major implications for the roles of QNs and NAs. The study therefore also sought to evaluate the effect of three organisational modes, primary, team and functional nursing, on the work and work perceptions of both grades. A questionnaire was developed which discriminated between organisational modes. This was used to select three wards from each mode (nine in total) for participation in the study. Within each ward, four QNs and four NAs were chosen randomly for inclusion. Data were collected by direct observation and semi-structured interviews. Each subject also completed a Work Environment Scale. The most important differences were found across organisational mode, with QNs and NAs within modes engaging in similar patterns of work, verbal interactions with patients and regarding their work environment similarly. This suggests a culture exists within each organisational mode which permeates the work of both grades of staff. Primary wards were generally found to differ from team and functional wards, with both QNs and NAs regarding their work more positively and working in more therapeutic ways. The study has important implications for the debate about which grade of staff is most suited to caring for elderly patients. It is argued NAs are capable of providing therapeutic care for elderly patients within a pattern of ward organisation which facilitates sustained nursing staff-patient allocation and appropriate supervision and direction in the form of QNs working with NAs.Department of Health via the Nursing Research Studentship Scheme

Determining the sample size for a cluster-randomised trial: Bayesian hierarchical modelling of the ICC estimate

In common with many cluster-randomised trials, it was difficult to determine the appropriate sample size for the planned trial of the effectiveness of a systematic voiding programme for post-stroke incontinence due to the lack of a robust estimate of the intra-cluster correlation coefficient (ICC). One approach to overcome this problem is a method of combining ICC values in the Bayesian framework (Turner et al. 2005). We adopted this approach and used Bayesian hierarchical modelling to estimate the ICC

What can management theories offer evidence-based practice? A comparative analysis of measurement tools for organisational context

Background: Given the current emphasis on networks as vehicles for innovation and change in health service delivery, the ability to conceptualise and measure organisational enablers for the social construction of knowledge merits attention. This study aimed to develop a composite tool to measure the organisational context for evidence-based practice (EBP) in healthcare. Methods: A structured search of the major healthcare and management databases for measurement tools from four domains: research utilisation (RU), research activity (RA), knowledge management (KM), and organisational learning (OL). Included studies were reports of the development or use of measurement tools that included organisational factors. Tools were appraised for face and content validity, plus development and testing methods. Measurement tool items were extracted, merged across the four domains, and categorised within a constructed framework describing the absorptive and receptive capacities of organisations. Results: Thirty measurement tools were identified and appraised. Eighteen tools from the four domains were selected for item extraction and analysis. The constructed framework consists of seven categories relating to three core organisational attributes of vision, leadership, and a learning culture, and four stages of knowledge need, acquisition of new knowledge, knowledge sharing, and knowledge use. Measurement tools from RA or RU domains had more items relating to the categories of leadership, and acquisition of new knowledge; while tools from KM or learning organisation domains had more items relating to vision, learning culture, knowledge need, and knowledge sharing. There was equal emphasis on knowledge use in the different domains. Conclusion: If the translation of evidence into knowledge is viewed as socially mediated, tools to measure the organisational context of EBP in healthcare could be enhanced by consideration of related concepts from the organisational and management sciences. Comparison of measurement tools across domains suggests that there is scope within EBP for supplementing the current emphasis on human and technical resources to support information uptake and use by individuals. Consideration of measurement tools from the fields of KM and OL shows more content related to social mechanisms to facilitate knowledge recognition, translation, and transfer between individuals and groups

Interventions for treating urinary incontinence after stroke in adults

Background Urinary incontinence can affect 40% to 60% of people admitted to hospital after a stroke, with 25% still having problems when discharged from hospital and 15% remaining incontinent after one year. This is an update of a review published in 2005 and updated in 2008. Objectives To assess the effects of interventions for treating urinary incontinence after stroke in adults at least one‐month post‐stroke. Search methods We searched the Cochrane Incontinence and Cochrane Stroke Specialised Registers (searched 30 October 2017 and 1 November 2017 respectively), which contain trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In‐Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP and handsearched journals and conference proceedings. Selection criteria We included randomised or quasi‐randomised controlled trials. Data collection and analysis Two review authors independently undertook data extraction, risk of bias assessment and implemented GRADE. Main results We included 20 trials (reporting 21 comparisons) with 1338 participants. Data for prespecified outcomes were not available except where reported below. Intervention versus no intervention/usual care Behavioural interventions: Low‐quality evidence suggests behavioural interventions may reduce the mean number of incontinent episodes in 24 hours (mean difference (MD) –1.00, 95% confidence interval (CI) –2.74 to 0.74; 1 trial; 18 participants; P = 0.26). Further, low‐quality evidence from two trials suggests that behavioural interventions may make little or no difference to quality of life (SMD ‐0.99, 95% CI ‐2.83 to 0.86; 55 participants). Specialised professional input interventions: One trial of moderate‐quality suggested structured assessment and management by continence nurse practitioners probably made little or no difference to the number of people continent three months after treatment (risk ratio (RR) 1.28, 95% CI 0.81 to 2.02; 121 participants; equivalent to an increase from 354 to 453 per 1000, 95% CI 287 to 715). Complementary therapy: Five trials assessed complementary therapy using traditional acupuncture, electroacupuncture and ginger‐salt‐partitioned moxibustion plus routine acupuncture. Low‐quality evidence from five trials suggested that complementary therapy may increase the number of participants continent after treatment; participants in the treatment group were three times more likely to be continent (RR 2.82, 95% CI 1.57 to 5.07; 524 participants; equivalent to an increase from 193 to 544 per 1000, 95% CI 303 to 978). Adverse events were reported narratively in one study of electroacupuncture, reporting on bruising and postacupuncture abdominal pain in the intervention group. Physical therapy: Two trials reporting three comparisons suggest that physical therapy using transcutaneous electrical nerve stimulation (TENS) may reduce the mean number of incontinent episodes in 24 hours (MD –4.76, 95% CI –8.10 to –1.41; 142 participants; low‐quality evidence). One trial of TENS reporting two comparisons found that the intervention probably improves overall functional ability (MD 8.97, 95% CI 1.27 to 16.68; 81 participants; moderate‐quality evidence). Intervention versus placebo Physical therapy: One trial of physical therapy suggests TPTNS may make little or no difference to the number of participants continent after treatment (RR 0.75, 95% CI 0.19 to 3.04; 54 participants) or number of incontinent episodes (MD –1.10, 95% CI –3.99 to 1.79; 39 participants). One trial suggested improvement in the TPTNS group at 26‐weeks (OR 0.04, 95% CI 0.004 to 0.41) but there was no evidence of a difference in perceived bladder condition at six weeks (OR 2.33, 95% CI 0.63 to 8.65) or 12 weeks (OR 1.22, 95% CI 0.29 to 5.17). Data from one trial provided no evidence that TPTNS made a difference to quality of life measured with the ICIQLUTSqol (MD 3.90, 95% CI –4.25 to 12.05; 30 participants). Minor adverse events, such as minor skin irritation and ankle cramping, were reported in one study. Pharmacotherapy interventions: There was no evidence from one study that oestrogen therapy made a difference to the mean number of incontinent episodes per week in mild incontinence (paired samples, MD –1.71, 95% CI –3.51 to 0.09) or severe incontinence (paired samples, MD –6.40, 95% CI –9.47 to –3.33). One study reported no adverse events. Specific intervention versus another intervention Behavioural interventions: One trial comparing a behavioural intervention (timed voiding) with a pharmacotherapy intervention (oxybutynin) contained no useable data. Complementary therapy: One trial comparing different acupuncture needles and depth of needle insertion to assess the effect on incontinence reported that, after four courses of treatment, 78.1% participants in the elongated needle group had no incontinent episodes versus 40% in the filiform needle group (57 participants). This trial was assessed as unclear or high for all types of bias apart from incomplete outcome data. Combined intervention versus single intervention One trial compared a combined intervention (sensory motor biofeedback plus timed prompted voiding) against a single intervention (timed voiding). The combined intervention may make little or no difference to the number of participants continent after treatment (RR 0.55, 95% CI 0.06 to 5.21; 23 participants; equivalent to a decrease from 167 to 92 per 1000, 95% CI 10 to 868) or to the number of incontinent episodes (MD 2.20, 95% CI 0.12 to 4.28; 23 participants). Specific intervention versus attention control Physical therapy interventions: One study found TPTNS may make little or no difference to the number of participants continent after treatment compared to an attention control group undertaking stretching exercises (RR 1.33, 95% CI 0.38 to 4.72; 24 participants; equivalent to an increase from 250 to 333 per 1000, 95% CI 95 to 1000). Authors' conclusions There is insufficient evidence to guide continence care of adults in the rehabilitative phase after stroke. As few trials tested the same intervention, conclusions are drawn from few, usually small, trials. CIs were wide, making it difficult to ascertain if there were clinically important differences. Only four trials had adequate allocation concealment and many were limited by poor reporting, making it impossible to judge the extent to which they were prone to bias. More appropriately powered, multicentre trials of interventions are required to provide robust evidence for interventions to improve urinary incontinence after stroke

Does repetitive task training improve functional activity after stroke? A Cochrane systematic review and meta-analysis.

Repetitive task training resulted in modest improvement across a range of lower limb outcome measures, but not upper limb outcome measures. Training may be sufficient to have a small impact on activities of daily living. Interventions involving elements of repetition and task training are diverse and difficult to classify: the results presented are specific to trials where both elements are clearly present in the intervention, without major confounding by other potential mechanisms of action

Developing clinical academic researchers: insights from practitioners and managers in nursing, midwifery and allied health

Background: Developing a clinical academic role in Nursing, Midwifery and the Allied Health Professions (NMAHP) is challenging due to lack of a national career pathway, recognition and understanding of the role. Aims: This evaluation explored perspectives of aspiring or active clinical academics and health care managers in NMAHP about the benefits, barriers and enablers of engagement in these career pathways. Methods: Eight workshops were facilitated across England (four each for managers and prospective clinical academics); 162 participants shared their experiences and perceptions of clinical academic research activities. Findings: Three major themes were identified related to the perceived benefits, barriers and enablers of engagement in these career pathways: Building health research capacity; Building individuals’ health research capability; and Improving patient care. Conclusion: This report demonstrates factors that are valued and perceived to be working well by practitioners and their clinical service managers, and highlights key priorities for further strategic support

Repetitive Task Training for Improving Functional Ability After Stroke: A major update of a Cochrane Review

Repetitive task training (RTT) involves the active practice of task-specific motor activities and is a component of current therapy approaches in stroke rehabilitation

A systematic review of repetitive task training with modelling of resource use, costs and effectiveness

OBJECTIVES: To determine whether repetitive functional task practice (RFTP) after stroke improves limb-specific or global function or activities of daily living and whether treatment effects are dependent on the amount of practice, or the type or timing of the intervention. Also to provide estimates of the cost-effectiveness of RFTP. DATA SOURCES: The main electronic databases were searched from inception to week 4, September 2006. Searches were also carried out on non-English-language databases and for unpublished trials up to May 2006. REVIEW METHODS: Standard quantitative methods were used to conduct the systematic review. The measures of efficacy of RFTP from the data synthesis were used to inform an economic model. The model used a pre-existing data set and tested the potential impact of RFTP on cost. An incremental cost per quality-adjusted life-year (QALY) gained for RFTP was estimated from the model. Sensitivity analyses around the assumptions made for the model were used to test the robustness of the estimates. RESULTS: Thirty-one trials with 34 intervention-control pairs and 1078 participants were included. Overall, it was found that some forms of RFTP resulted in improvement in global function, and in both arm and lower limb function. Overall standardised mean difference in data suitable for pooling was 0.38 [95% confidence interval (CI) 0.09 to 0.68] for global motor function, 0.24 (95% CI 0.06 to 0.42) for arm function and 0.28 (95% CI 0.05 to 0.51) for functional ambulation. Results suggest that training may be sufficient to have an impact on activities of daily living. Retention effects of training persist for up to 6 months, but whether they persist beyond this is unclear. There was little or no evidence that treatment effects overall were modified by time since stroke or dosage of task practice, but results for upper limb function were modified by type of intervention. The economic modelling suggested that RFTP was cost-effective. Given a threshold for cost-effectiveness of 20,000 pounds per QALY gained, RFTP is cost-effective so long as the net cost per patient is less than 1963 pounds. This result showed some sensitivity to the assumptions made for the model. The cost-effectiveness of RFTP tends to stem from the relatively modest cost associated with this intervention. CONCLUSIONS: The evidence suggests that some form of RFTP can be effective in improving lower limb function at any time after stroke, but that the duration of intervention effect is unclear. There is as yet insufficient good-quality evidence to make any firm recommendations for upper limb interventions. If task-specific training is used, adverse effects should be monitored. While the effectiveness of RFTP is relatively modest, this sort of intervention appears to be cost-effective. Owing to the large number of ongoing trials, this review should be updated within 2 years and any future review should include a comparison against alternative treatments. Further research should evaluate RFTP upper limb interventions and in particular constraint-induced movement therapy, address practical ways of delivering RFTP interventions, be directed towards the evaluation of suitable methods to maintain functional gain, and be powered to detect whether RFTP interventions are cost-effective
