Observation-based early warning scoring systems (EWSS) have been developed to improve the outcome of critically ill patients by triggering early critical care intervention. To date, none of these scoring systems have been evaluated in cancer patients or stem cell transplant (SCT) recipients. The aim of this study was to validate 3 established EWSS (modified early warning score [MEWS], patient-at-risk score [PARS], and Leed's early warning score [LEWS]) in adult recipients of Allogeneic SCT (Allo-SCT) and to determine their usefulness at predicting survival. We retrospectively analyzed the physiologic observations during the initial admission of 43 Allo-SCT recipients. Respiratory dysfunction was the most common (40 patients, 93%) event. All 3 EWSS revealed high accuracy in predicting in-hospital survival. The cutoff level associated with a high risk of in-hospital mortality was 7. Of 8 patients with a LEWS = 7, 6 died during their initial admission, whereas no patient with a lower score died (specificity 95%, sensitivity 100%). Acute clinical deterioration during the initial admission appeared to have an adverse effect on overall survival: in-hospital survivors with a LEWS >3 during their admission had a shorter median survival than patients with LEWS < or = 3, P = .018. This is the first study to validate EWSS in Allo-SCT and demonstrate that these systems are highly predictive of in-hospital and overall survival.

BackgroundDespite the evidence that many stroke survivors report longer term unmet needs, the provision of longer term care is limited. To address this, we are conducting a programme of research to develop an evidence-based and replicable longer term care strategy. The developed complex intervention (named New Start), which includes needs identification, exploration of social networks and components of problem solving and self-management, was designed to improve quality of life by addressing unmet needs and increasing participation.Methods/DesignA multicentre, cluster randomised controlled feasibility trial designed to inform the design of a possible future definitive cluster randomised controlled trial (cRCT) and explore the potential clinical and cost-effectiveness of New Start.Ten stroke services across the UK will be randomised on a 1:1 basis either to implement New Start or continue with usual care only. New Start will be delivered by trained facilitators and will be offered to all stroke survivors within the services allocated to the intervention arm. Stroke survivors will be eligible for the trial if they are 4–6 months post-stroke and residing in the community. Carers (if available) will also be invited to take part. Invitation to participate will be initiated by post and outcome measures will be collected via postal questionnaires at 3, 6 and 9 months after recruitment. Outcome data relating to perceived health and disability, wellbeing and quality of life as well as unmet needs will be collected. A ‘study within a trial’ (SWAT) is planned to determine the most acceptable format in which to provide the postal questionnaires. Details of health and social care service usage will also be collected to inform the economic evaluation. The feasibility of recruiting services and stroke survivors to the trial and of collecting postal outcomes will be assessed and the potential for effectiveness will be investigated. An embedded process evaluation (reported separately) will assess implementation fidelity and explore and clarify causal assumptions regarding implementation.DiscussionThis feasibility trial with embedded process evaluation will allow us to gather important and detailed data regarding methodological and implementation issues to inform the design of a possible future definitive cRCT of this complex intervention.Trial RegistrationISRCTN38920246.

Background It is reported that the longer-term outcomes for stroke survivors are poor, with a range of unmet needs identified. Objectives The aims were to develop and test a longer-term stroke care strategy focused on improving the quality of life of stroke survivors and their carers by addressing unmet needs, and maintenance and enhancement of participation (i.e. involvement in life situations). Design Five overlapping workstreams were undertaken – (1) refinement of content by semistructured interviews with stroke survivors and their carers and by a review of the literature to inform content and delivery of the care strategy; (2) exploration of service models by national survey and focus groups with purposely selected services; (3) intervention development by interaction with a reference group of stroke survivors, carers, and health and social care professionals; (4) refinement and pilot implementation of the developed intervention in three stroke services (case studies); and (5) a cluster randomised controlled feasibility trial in 10 stroke services across England and Wales. Setting The intervention development work and feasibility trial were in stroke services (inclusive of primary, secondary, community and social care provision) across England and Wales. Participants Participants were stroke survivors resident in the community and their carers, and health and social care professionals in the included stroke services. Data sources Interviews with 28 stroke survivors and their carers at least 9 months post stroke ascertained their needs and the barriers to and facilitators of addressing those needs. Additional literature reviews identified 23 needs. No evidence-based interventions to address these needs were reported; self-management was highlighted as a possible delivery mechanism. In workstream 2, a national survey revealed that the most common model of stroke service provision was care up to 12 months post stroke, reported by 46 (40%) services. Thirty-five (30%) services provided care up to 6 months post stroke and 35 (30%) provided care beyond 12 months, thus identifying 6 months post stroke as an appropriate delivery point for a new intervention. Through focus groups in a range of services, stroke survivors’ perceived unmet needs and the barriers to and enablers of service provision were identified. Intervention Using information obtained in workstreams 1 and 2 and working closely with a stakeholder reference group, we developed an intervention based on the unmet needs prioritised by stroke survivors and their carers (workstream 3). In workstream 4, action groups (clinicians, stroke survivors and researchers) were established in three stroke services that led implementation in their service and contributed to the iterative refinement of the intervention, associated training programme and implementation materials. The intervention (called New Start) was delivered at 6 months post stroke. Key components were problem-solving self-management with survivors and carers, help with obtaining usable information, and helping survivors and their carers build sustainable, flexible support networks. Results A cluster randomised feasibility trial (workstream 5) was successfully implemented in 10 stroke services across England and Wales, with associated process and health economic evaluations. Five services were randomised to provide New Start, while five continued with usual care; 269 participants were recruited. Progression criteria – in terms of our pre-determined (red, amber, green) criteria for progress to a full trial: target stroke survivor recruitment rates were achieved, on average, across sites (24.1 per site over 6 months, green); 216 (80.3%) registered stroke survivors returned follow-up questionnaires at 9 months (84.1% in the intervention arm and 75.8% in the usual care arm, green); according to data reported by sites, overall, 95.2% of registered stroke survivors were offered at least one session of the intervention (green); all five intervention sites had at least two facilitators deemed competent, delivered the New Start intervention and provided it to stroke survivors (green). However, at some sites, there were concerns regarding the number of stroke survivors being offered, accepting and receiving the intervention. Only small differences in outcomes and costs were observed between the New Start and usual care groups, and considerable uncertainty around the cost-effectiveness remains. Conclusions We report a complex programme of work that has described the longer-term needs of stroke survivors and highlighted evidence and service gaps. Working closely with stroke survivors, an intervention was developed that has been refined in three services and feasibility tested in a cluster randomised controlled trial. Further refinement of the target population and optimisation of the intervention materials is required prior to a full randomised controlled trial evaluation. Future work Optimisation of the intervention, and clearer specification of recipients, are required prior to a full trial evaluation. Trial registration Current Controlled Trials ISRCTN38920246.
