RESUMEN
BACKGROUND: In response to concerns about high hospital mortality rates, patient and carer complaints, a Mid Staffordshire NHS Foundation Trust public inquiry was conducted at the request of the UK government. This inquiry found serious failures in the quality of basic care provided and as a consequence, recommended that patients should have more regular visits, organised at predictable times from nursing staff. Intentional rounding, also known as nursing ward rounds, was widely adopted to meet this need. OBJECTIVE: To test, refine or refute eight programme theories to understand what works, for whom, and in what circumstances. SETTING: Six wards (older people and acute wards) in three NHS trusts in England. PARTICIPANTS: Board level and senior nursing managers (N = 17), nursing ward staff (N = 33), allied health and medical professionals (N = 26), patients (N = 34) and relatives (N = 28) participated in an individual, in-depth interview using the realist method. In addition, ward-based nurses (N = 39) were shadowed whilst they conduced intentional rounds (240 rounds in total) and the direct care of patients (188 h of patient care in total) was observed. METHODS: The mixed methods design included: Phase (1) Theory development - A realist synthesis was undertaken to identify any programme theories which were tested, refined and/or refuted, using data from phases 2 and 3; Phase (2) A survey of all English NHS acute Trusts; Phase (3) Six case studies of wards involving realist interviews, shadowing and non-participant observations, analysis of ward outcome and cost data; and Phase (4) Synthesis of findings from phases 1, 2 and 3. RESULTS: The realist synthesis identified eight programme theories of intentional rounding: 'Consistency and comprehensiveness', 'Accountability', 'Visibility of nurses', 'Anticipation', 'Allocated time to care', 'Nurse-patient relationships', 'Multi-disciplinary teamwork and communication' and 'Patient empowerment'. Key findings showed that of the original eight programme theories of intentional rounding, only two partially explained how the intervention worked ('Consistency and comprehensiveness' and 'Accountability'). Of the remaining six programme theories, the evidence for two was inconclusive ('Visibility of nurses' and 'Anticipation') and there was no evidence for four ('Allocated time to care'; 'Nurse-patient relationships'; 'Multi-disciplinary teamwork and communication'; and 'Patient empowerment'). CONCLUSIONS: This first theory-informed evaluation of intentional rounding, demonstrates that the effectiveness of intentional rounding in the English healthcare context is very weak. Furthermore, the evidence collected in this study has challenged and refuted some of the underlying assumptions about how intentional rounding works. This study has demonstrated the crucial role context plays in determining the effectiveness of an intervention and how caution is needed when implementing interventions developed for the health system of one country into another.

High-temperature superconductors (HTS) could enable high-field magnets stronger than is possible with Nb-Ti and Nb3Sn, but two challenges have so far been the low engineering critical current density JE, especially in high-current cables, and the danger of quenches. Most HTS magnets made so far have been made out of REBCO coated conductor. Here we demonstrate stable, reliable and training-quench-free performance of Bi-2212 racetrack coils wound with a Rutherford cable fabricated from wires made with a new precursor powder. These round multifilamentary wires exhibited a record JE up to 950 A/mm2 at 30 T at 4.2 K. These coils carried up to 8.6 kA while generating 3.5 T at 4.2 K at a JE of 1020 A/mm2. Different from the unpredictable training performance of Nb-Ti and Nb3Sn magnets, these Bi-2212 magnets showed no training quenches and entered the flux flow state in a stable manner before thermal runaway and quench occurred. Also different from Nb-Ti, Nb3Sn, and REBCO magnets for which localized thermal runaways occur at unpredictable locations, the quenches of Bi-2212 magnets consistently occurred in the high field regions over a long conductor length. These characteristics make quench detection simple, enabling safe protection, and suggest a new paradigm of constructing quench-predictable superconducting magnets from Bi-2212.
RESUMEN
BACKGROUND: Intentional rounding (IR) is a structured process whereby nurses conduct one to two hourly checks with every patient using a standardised protocol. OBJECTIVE: A realist synthesis of the evidence on IR was undertaken to develop IR programme theories of what works, for whom, in what circumstances and why. METHODS: A three-stage literature search and a stakeholder consultation event was completed. A variety of sources were searched, including AMED, CINAHL, MEDLINE, PsycINFO, HMIC, Google and Google Scholar, for published and unpublished literature. In line with realist synthesis methodology, each study's 'fitness for purpose' was assessed by considering its relevance and rigour. RESULTS: A total of 44 papers met the inclusion criteria. To make the programme theories underpinning IR explicit, we identified eight a priori propositions: (1) when implemented in a comprehensive and consistent way, IR improves healthcare quality and satisfaction, and reduces potential harms; (2) embedding IR into daily routine practice gives nurses 'allocated time to care'; (3) documenting IR checks increases accountability and raises fundamental standards of care; (4) when workload and staffing levels permit, more frequent nurse-patient contact improves relationships and increases awareness of patient comfort and safety needs; (5) increasing time when nurses are in the direct vicinity of patients promotes vigilance, provides reassurance and reduces potential harms; (6) more frequent nurse-patient contact enables nurses to anticipate patient needs and take pre-emptive action; (7) IR documentation facilitates teamwork and communication; and (8) IR empowers patients to ask for what they need to maintain their comfort and well-being. Given the limited evidence base, further research is needed to test and further refine these propositions. CONCLUSIONS: Despite widespread use of IR, this paper highlights the paradox that there is ambiguity surrounding its purpose and limited evidence of how it works in practice.

BACKGROUND: Nurses leaving their jobs and the profession are an issue of international concern, with supply-demand gaps for nurses reported to be widening. There is a large body of existing literature, much of which is already in review form. In order to advance the usefulness of the literature for nurse and human resource managers, we undertook an overview (review of systematic reviews). The aim of the overview was to identify high quality evidence of the determinants and consequences of turnover in adult nursing. METHODS: Reviews were identified which were published between 1990 and January 2015 in English using electronic databases (the Cochrane Database of Systematic Reviews, MEDLINE, EMBASE, Applied Social Sciences Index and Abstracts, CINAHL plus and SCOPUS) and forward searching. All stages of the review were conducted in parallel by two reviewers. Reviews were quality appraised using the Assessment of Multiple Systematic Reviews and their findings narratively synthesised. RESULTS: Nine reviews were included. We found that the current evidence is incomplete and has a number of important limitations. However, a body of moderate quality review evidence does exist giving a picture of multiple determinants of turnover in adult nursing, with - at the individual level - nurse stress and dissatisfaction being important factors and -at the organisational level - managerial style and supervisory support factors holding most weight. The consequences of turnover are only described in economic terms, but are considered significant. CONCLUSIONS: In making a quality assessment of the review as well as considering the quality of the included primary studies and specificity in the outcomes they measure, the overview found that the evidence is not as definitive as previously presented from individual reviews. Further research is required, of rigorous research design, whether quantitative or qualitative, particularly against the outcome of actual turnover as opposed to intention to leave. TRIAL REGISTRATION: PROSPERO Registration 17 March 2015: CRD42015017613 .

INTRODUCTION: Intentional rounding (IR) is a structured process whereby nurses in hospitals carry out regular checks, usually hourly, with individual patients using a standardised protocol to address issues of positioning, pain, personal needs and placement of items. The widespread implementation of IR across the UK has been driven by the recommendations of the Francis Inquiry although empirical evidence of its effectiveness is poor. This paper presents a protocol of a multimethod study using a realist evaluation approach to investigate the impact and effectiveness of IR in hospital wards on the organisation, delivery and experience of care from the perspective of patients, their family members and staff. METHODS AND ANALYSIS: The study will be conducted in four phases. Phase 1: theory development using realist synthesis to generate hypotheses about what the mechanisms of IR may be, what particular groups may benefit most or least and what contextual factors might be important to its success or failure which will be tested in subsequent phases of the study. Phase 2: a national survey of all NHS acute trusts to explore how IR is implemented and supported across England. Phase 3: case studies to explore how IR is implemented 'on the ground', including individual interviews with patients, family members and staff, non-participant observation, retrieval of routinely collected patient outcomes and cost analysis. Phase 4: accumulative data analysis across the phases to scrutinise data for patterns of congruence and discordance and develop an overall evaluation of what aspects of IR work, for whom and in what circumstances. ETHICS AND DISSEMINATION: The study has been approved by NHS South East Coast-Surrey Research Ethics Committee. Findings will be published in a wide range of outputs targeted at key audiences, including patient and carer organisations, nursing staff and healthcare managers.

BACKGROUND: Nurse turnover is an issue of concern in health care systems internationally. Understanding which interventions are effective to reduce turnover rates is important to managers and health care organisations. Despite a plethora of reviews of such interventions, strength of evidence is hard to determine. OBJECTIVE: We aimed to review literature on interventions to reduce turnover in nurses working in the adult health care services in developed economies. METHOD: We conducted an overview (systematic review of systematic reviews) using the Cochrane Database of Systematic Reviews, MEDLINE, EMBASE, Applied Social Sciences Index and Abstracts, CINAHL plus and SCOPUS and forward searching. We included reviews published between 1990 and January 2015 in English. We carried out parallel blinded selection, extraction of data and assessment of bias, using the Assessment of Multiple Systematic Reviews. We carried out a narrative synthesis. RESULTS: Despite the large body of published reviews, only seven reviews met the inclusion criteria. These provide moderate quality review evidence, albeit from poorly controlled primary studies. They provide evidence of effect of a small number of interventions which decrease turnover or increase retention of nurses, these being preceptorship of new graduates and leadership for group cohesion. CONCLUSION: We highlight that a large body of reviews does not equate with a large body of high quality evidence. Agreement as to the measures and terminology to be used together with well-designed, funded primary research to provide robust evidence for nurse and human resource managers to base their nurse retention strategies on is urgently required.
