'It was like he was in the room with us': patients' and carers' perspectives of telemedicine in acute stroke.

BACKGROUND: Telemedicine can facilitate delivery of thrombolysis in acute stroke. The aim of this qualitative study was to explore patients' and carers' views of their experiences of using a stroke telemedicine system in order to contribute to the development of reliable and acceptable telemedicine systems and training for health-care staff. METHOD: We recruited patients who had, and carers who were present at, recent telemedicine consultations for acute stroke in three hospitals in NW England. Semi-structured interviews were conducted using an interview guide based on normalization process theory (NPT). Thematic analysis was undertaken. RESULTS: We conducted 24 interviews with 29 participants (16 patients; 13 carers). Eleven interviews pertained to 'live' telemedicine assessments (at the time of admission); nine had mock-up telemedicine assessments (within 48 h of admission); four had both assessments. Using the NPT domains as a framework for analysis, factors relating to coherence (sense making) included people's knowledge and understanding of telemedicine. Cognitive participation (relational work) included interaction between staff and with patients and carers. Issues relating to collective action (operational work) included information exchange and support, and technical matters. Findings relating to reflexive monitoring (appraisal) included positive and negative impressions of the telemedicine process, and emotional reactions. CONCLUSION: Although telemedicine was well accepted by many participants, its use added an additional layer of complexity to the acute stroke consultation. The 'remote' nature of the consultation posed challenges for some patients. These issues may be ameliorated by clear information for patients and carers, staff interpersonal skills, and teamworking.

"Can you send an ambulance please?": a comparison of callers' requests for emergency medical dispatch in non-stroke and stroke calls.

BACKGROUND: Identifying 'true stroke' from an emergency medical services (EMS) call is challenging, with over 50% of strokes being misclassified. In a previous study, we examined the relationship between callers' descriptions of stroke symptoms to the emergency medical dispatcher and the subsequent classification and prioritisation of EMS response. The aim of this subsequent study was to explore further the use of keywords by callers when making emergency calls, comparing stroke and non-stroke calls. METHODS: All non-stroke calls to one EMS dispatch centre between 8 March 2010 and 14 March 2010 were analysed. These were compared with the stroke calls made to one EMS dispatch centre between 1 October 2006 and 30 September 2007. Content analysis was used to explore the problems described by the caller, and findings were compared between non-stroke and stroke calls. RESULTS: 277 non-stroke calls were identified. Only eight (3%) callers mentioned stroke, 12 (4%) and 11 (4%) mentioned limb weakness and speech problems, respectively, while no caller mentioned more than one classic stroke symptom. This contrasted with 473 stroke calls, where 188 (40%) callers mentioned stroke, 70 (15%) limb weakness and 72 (15%) speech problems, and 14 (3%) mentioned more than one classic stroke symptom. CONCLUSIONS: People who contact the EMS about non-stroke conditions rarely say stroke, limb weakness, speech problems or facial weakness. These words are more frequently used when people contact the EMS about stroke, although many calls relating to stroke patients do not mention any of these keywords.

Using telemedicine for acute stroke assessment.

In acute stroke care, urgent specialist assessment and treatment are essential to reduce the risk of death and disability. However, many patients do not receive them due to a lack of specialist services. One solution is to use telemedicine. This can give all patients with acute stroke symptoms access to immediate expert assessment and advice, regardless of when and where they present to hospital. This article describes a telemedicine system developed and implemented in Lancashire and Cumbria. In its first year of operation, 319 patients received a telestroke video assessment with a consultant stroke physician; 131 of these patients were given thrombolysis. We discuss how the service was designed, staff training and development, and the implications for nursing practice. The development of a standardised telemedicine toolkit that may facilitate future telemedicine projects is also discussed.

The identification of acute stroke: an analysis of emergency calls.

BACKGROUND: Accurate dispatch of emergency medical services at the onset of acute stroke is vital in expediting assessment and treatment. We examined the relationship between callers' description of potential stroke symptoms to the emergency medical dispatcher and the subsequent classification and prioritisation of emergency medical services response. AIM: To identify key 'indicator' words used by people making emergency calls for suspected stroke, comparing these with the subsequent category of response given by the emergency medical dispatcher. METHOD: A retrospective chart review (hospital and emergency medical services) in North West England (October 1, 2006 to September 30, 2007) identified digitally recorded emergency medical services calls, which related to patients who had a diagnosis of suspected stroke at some point on the stroke pathway (from the emergency medical services call taker through to final medical diagnosis). Using content analysis, words used to describe stroke by the caller were recorded. A second researcher independently followed the same procedure in order to produce a list of 'indicator' words. Description of stroke-specific and nonstroke-specific problems reported by the caller was compared with subsequent emergency medical services dispatch coding and demographic features. RESULTS: Six hundred forty-three calls were made to emergency medical services of which 592 (92%) had complete emergency medical services and hospital data. The majority of callers were female (67%) and family members (55%). The most frequently reported problems first said by callers to the emergency medical dispatcher were collapse or fall (26%) and stroke (25%). Callers who identified that the patient was having a stroke were correct in 89% of cases. Calls were dispatched as stroke in 45% of cases, of which 83% had confirmed stroke. Of the first reported problems, Face Arm Speech Test stroke symptoms were mentioned in less than 5% of calls, with speech problems being the most common symptom. No callers mentioned all three Face Arm Speech Test symptoms. CONCLUSION: Callers who contacted emergency medical services for suspected stroke and said stroke as the first reported problem were often correct. Calls categorised as stroke by the emergency medical dispatcher were commonly confirmed as stroke in the hospital. Speech problems were the most commonly reported element of the Face Arm Speech Test test to be reported by callers. Recognition of possible stroke diagnosis in fall and other presentations should be considered by emergency medical dispatchers. Further development and training are needed in the community to improve prehospital stroke recognition in order to expedite hyperacute stroke care.

Postal and face-to-face administration of stroke outcome measures: can mixed modes be used?

BACKGROUND AND PURPOSE: Different modes of administration are used to collect stroke outcomes, even within the same study, potentially leading to different results. We investigated the effect of administration mode (postal questionnaire; face-to-face interview) on self-reports of activities of daily living and mood. METHODS: The study was nested within a poststroke motivational interviewing trial. Activities of daily living (Barthel; Nottingham Extended) and mood (General Health Questionnaire; Yale) were collected at 3 and 12 months via postal questionnaire. Participants were approached to respond again via face-to-face interview. Paired t tests (McNemar test) and intraclass correlation coefficients (Cohen κ) were used, with 95% CI, to compare scores (items). RESULTS: Forty-four participants consented. Only Barthel scores were significantly different; they were 1.0 (95% CI, 0.5-1.6) higher face-to-face. The intraclass correlation coefficient for the Barthel was 0.90; for the other scales it was between 0.83 and 0.87. The Yale κ was 0.72. CONCLUSIONS: Modes of administration might be used interchangeably, albeit in conjunction with corrections for the Barthel.

'Is he awake?': dialogues between callers and call handlers about consciousness during emergency calls for suspected acute stroke.

BACKGROUND: Altered consciousness is an important symptom of acute stroke but assessment may be challenging when cognitive or language deficits are present. Callers are routinely questioned about conscious level by emergency medical services (EMS) call handlers for any presenting problem. OBJECTIVE: This study aimed to identify and compare how patients' conscious level was questioned, described and interpreted by callers and call handlers during acute stroke calls. METHOD: Audio recordings of 643 EMS calls for patients with suspected or confirmed acute stroke, admitted to one hospital in North West England over a 12-month period were retrieved from EMS recordings. Calls from primary care physicians were excluded. The caller's response to two standard questions was coded: 'Is the patient conscious?' and 'Is he/she completely awake?', and other relevant dialogue. Responses which suggested misinterpretation of terms relating to conscious level, or where the call handler used additional clarifying questions, were analysed in detail. RESULTS: 109/643 (17%) of the calls had an altered level of consciousness recorded on the ambulance report form. Calls often contained unscripted, protracted dialogue about conscious level. Conscious level was difficult for the caller to determine, miscommunicated, or conflated with breathing difficulties. CONCLUSION: Ambiguities and contradictions in dialogue about conscious level arise during ambulance calls for suspected and confirmed stroke. Further study is needed to identify whether these issues also arise in non-stroke calls, and which terms are best understood by the public in describing conscious level.

Callers' experiences of making emergency calls at the onset of acute stroke: a qualitative study.

BACKGROUND: Rapid access to emergency medical services (EMS) is essential at the onset of acute stroke, but significant delays in contacting EMS often occur. OBJECTIVE: To explore factors that influence the caller's decision to contact EMS at the onset of stroke, and the caller's experiences of the call. METHODS: Participants were identified through a purposive sample of admissions to two hospitals via ambulance with suspected stroke. Participants were interviewed using open-ended questions and content analysis was undertaken. RESULTS: 50 participants were recruited (median age 62 years, 68% female). Only one of the callers (2%) was the patient. Two themes were identified that influenced the initial decision to contact EMS at the onset of stroke: perceived seriousness, and receipt of lay or professional advice. Two themes were identified in relation to the communication between the caller and the call handler: symptom description by the caller, and emotional response to onset of stroke symptoms. CONCLUSIONS: Many callers seek lay or professional advice prior to contacting EMS and some believe that the onset of acute stroke symptoms does not warrant an immediate 999 call. More public education is needed to improve awareness of stroke and the need for an urgent response.

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

OBJECTIVE: To determine if repetitive task training after stroke improves functional activity. DESIGN: Systematic review and meta-analysis of trials comparing repetitive task training with attention control or usual care. DATA SOURCES: The Cochrane Stroke Trials Register, electronic databases of published, unpublished and non-English language papers; conference proceedings, reference lists, and trial authors. REVIEW METHODS: Included studies were randomized/quasi-randomized trials in adults after stroke where an active motor sequence aiming to improve functional activity was performed repetitively within a single training session. We used Cochrane Collaboration methods, resources, and software. RESULTS: We included 14 trials with 17 intervention-control pairs and 659 participants. Results were statistically significant for walking distance (mean difference 54.6, 95% confidence interval (95% CI) 17.5, 91.7); walking speed (standardized mean difference (SMD) 0.29, 95% CI 0.04, 0.53); sit-to-stand (standard effect estimate 0.35, 95% CI 0.13, 0.56), and activities of daily living: SMD 0.29, 95% CI 0.07, 0.51; and of borderline statistical significance for measures of walking ability (SMD 0.25, 95% CI 0.00, 0.51), and global motor function (SMD 0.32, 95% CI -0.01, 0.66). There were no statistically significant differences for hand/arm functional activity, lower limb functional activity scales, or sitting/standing balance/reach. CONCLUSION: 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.

Physiological monitoring in acute stroke: a literature review.

AIM: This paper is a report of a review of the literature that considers how physiological parameters may affect outcome after stroke and the implications of this evidence for monitoring. BACKGROUND: Throughout the world, the incidence of first-ever stroke is approximately 200 per 100,000 people per year [Sudlow et al. (1997). Stroke 28, 491]. Stroke is the third most common cause of mortality [Sarti et al. (2000). Stroke 31, 1588] and causes 5.54 million deaths worldwide [Murray & Lopez (1997). Lancet 349, 268]. Physiological monitoring is considered a fundamental component of acute stroke care. Currently, the strength of evidence to support its use and identify its components is unclear. Nurse-led physiological assessment and subsequent interventions in acute stroke may have the potential to improve survival and reduce disability. DATA SOURCES: Online bibliographic databases from 1966 to 2007, including MEDLINE, EMBASE, CINAHL, AMED, Cochrane and ZETOC, were searched systematically. We identified 475 published papers relating to blood pressure, oxygen saturation and positioning, blood glucose and body temperature. REVIEW METHODS: Titles and abstracts were reviewed independently by two reviewers and 61 relevant studies were read in full. The quality of included studies was assessed and proformas were used to record detailed data. A narrative synthesis described how the evidence from the papers could inform our understanding of physiological parameters and their association with outcome. RESULTS: Current evidence suggests that patient outcome is worse when physiological parameters deviate from 'normal' in the acute phase of stroke. CONCLUSIONS: The evidence supports the need for monitoring and recording of blood pressure, oxygen saturation (including consideration of positioning), blood glucose and body temperature in the acute phase of stroke. This review has reinforced the importance of monitoring physiological parameters in the acute phase of stroke and adds support to the recommendation that monitoring should play a key role within nursing care.
