Coronary Care Unit in a General Medical Ward

A five-bedded coronary care unit has been set up within a general medical ward without the provision of extra medical or nursing staff. During 30 months 1,000 patients were admitted. Sixty-three developed cardiac arrest; 28 were resuscitated successfully initially; and 18 were eventually discharged. The corresponding figures for the 28 patients with ventricular fibrillation treated by direct current defibrillation were 20 and 12 respectively. The mortality rate during the first three days (the usual length of stay in the unit) was 8·9% compared with 9·7% after transfer to the general ward. It is suggested that these results are comparable with those from more highly staffed purpose-built units.     

Prospective randomised study of an orthopaedic geriatric inpatient service.

A randomised controlled trial of two management regimens was carried out in women patients over 65 years of age with hip fractures. Ninety seven patients were admitted to a designated orthopaedic geriatric unit and 125 to orthopaedic wards. No difference was observed in mortality, length of stay, or placement of patients between the two groups. More medical conditions were recognised and treated in patients in the orthopaedic geriatric unit group. It is concluded that designated orthopaedic geriatric units can provide medical care to these patients and should be administered without additional cost.     

Changing patterns in drug therapy for ischemic heart disease

To determine the possible influence of studies on β-blocker therapy following myocardial infarction and the introduction of calcium-channel blockers on the prescribing habits of physicians in a large urban centre, the drug therapy received by 100 patients with ischemic heart disease (IHD) (50 with myocardial infarction and 50 with unstable angina) admitted to a university teaching hospital in 1980 was compared with that received by another such group of 100 patients admitted in 1983-84. The proportion of patients with myocardial infarction receiving drug therapy was significantly higher in 1983-84, at the time of both admission (p < 0.01) and discharge (p < 0.001). Much of the increase was due to greater use of β-blockers. Of the 50 patients with unstable angina in 1983-84, 20 were taking calcium-channel blockers when admitted, and 29 were taking them when discharged. In both 1980 and 1983-84 unstable angina was treated more vigorously than myocardial infarction. The results suggest that physicians have developed a more aggressive approach to drug therapy for IHD since the publication of the β-blocker studies and the introduction of calcium-channel blockers.     

Management of acute stroke in the elderly: follow-up of a controlled trial.

Follow-up of a controlled trial of the management of acute stroke in the elderly showed that the improvement in functional outcome at the time of discharge from hospital that had been achieved through establishing a stroke unit had disappeared by one year. Factors that might have contributed to this included overprotection by the families of patients who had been treated in the stroke unit, who were not permitted to carry out activities of daily living in which they were independent, and the early discharge from medical units of patients whose full rehabilitation potential had not been realised. Prolonging the benefits of short-term gains in functional outcome through the intervention of a stroke unit requires that all the links in the chain of stroke rehabilitation are maintained, including the proper orientation of patients'' families before discharge from hospital.     

Psychological and social evaluation in cases of deliberate self-poisoning seen in an accident department.

The outcome in 115 consecutive patients with mild self-poisoning seen by junior medical staff and discharged from the accident department was compared with that of 98 similar patients admitted to the medical wards. Psychiatrists saw only four patients in the accident department and 25 admissions. In making their assessments the junior medical staff considered psychosocial factors as well as the patients'' physical condition. Most patients recommended for further care, and discharged from the accident department, subsequently received it. Repetition rates were similar in the two groups and there had been no suicides when patients were followed up at one year. It is feasible for junior staff in an accident department to decide whether patients with self-poisoning need admission or may be discharged with or without subsequent referral for psychiatric or social work help.     

Effectiveness of geriatric rehabilitative care after fractures of the proximal femur in elderly women: a randomised clinical trial.

OBJECTIVE--To compare postoperative collaborative care between orthopaedic surgeons and physicians in geriatric medicine with routine orthopaedic care in elderly women with proximal femoral fracture. DESIGN--Exclusion of patients dying before fit enough to enter trial, those with pathological fractures, those likely to be discharged within seven days of entering the trial, and those remaining unfit for transfer to a peripheral hospital. Remainder allocated to two groups: treatment group and control group. SETTING--District hospital acute admission ward and rehabilitation ward. PATIENTS--144 sequentially admitted elderly women with proximal fracture of the femur; 36 excluded on above criteria and remainder entered into trial. INTERVENTION--Both treatment and control groups (n = 54 in each) received physiotherapy and other services. The treatment group also received thrice weekly supervision by a geriatrician. END POINTS--Physical independence, residence after discharge, and length of hospital stay. MEASUREMENTS AND MAIN RESULTS--At discharge significantly more patients in treatment group were independent in terms of activities of daily living than controls (41 v 25) and their median stay was 24 days (range 8-197) compared with 41 (9-365) (95% confidence intervals for difference 2 to 25). Significantly fewer treatment patients were discharged to institutional care (10% v 32%; 95% confidence interval for difference 6% to 37%) and more to their own homes (63% v 38%; 95% confidence interval for difference 6% to 44%). These beneficial effects were consistent across a range of ages and mental state. CONCLUSIONS--Both hospital and patient benefited when postoperative rehabilitation was provided in a setting specialising in such care for elderly patients with trauma.     

Cost-Effectiveness of a Specialist Geriatric Medical Intervention for Frail Older People Discharged from Acute Medical Units: Economic Evaluation in a Two-Centre Randomised Controlled Trial (AMIGOS)

BackgroundPoor outcomes and high resource-use are observed for frail older people discharged from acute medical units. A specialist geriatric medical intervention, to facilitate Comprehensive Geriatric Assessment, was developed to reduce the incidence of adverse outcomes and associated high resource-use in this group in the post-discharge period.ObjectiveTo examine the costs and cost-effectiveness of a specialist geriatric medical intervention for frail older people in the 90 days following discharge from an acute medical unit, compared with standard care.MethodsEconomic evaluation was conducted alongside a two-centre randomised controlled trial (AMIGOS). 433 patients (aged 70 or over) at risk of future health problems, discharged from acute medical units within 72 hours of attending hospital, were recruited in two general hospitals in Nottingham and Leicester, UK. Participants were randomised to the intervention, comprising geriatrician assessment in acute units and further specialist management, or to control where patients received no additional intervention over and above standard care. Primary outcome was incremental cost per quality adjusted life year (QALY) gained.ResultsWe undertook cost-effectiveness analysis for 417 patients (intervention: 205). The difference in mean adjusted QALYs gained between groups at 3 months was -0.001 (95% confidence interval [CI]: -0.009, 0.007). Total adjusted secondary and social care costs, including direct costs of the intervention, at 3 months were £4412 (€5624, $6878) and £4110 (€5239, $6408) for the intervention and standard care groups, the incremental cost was £302 (95% CI: 193, 410) [€385, $471]. The intervention was dominated by standard care with probability of 62%, and with 0% probability of cost-effectiveness (at £20,000/QALY threshold).ConclusionsThe specialist geriatric medical intervention for frail older people discharged from acute medical unit was not cost-effective. Further research on designing effective and cost-effective specialist service for frail older people discharged from acute medical units is needed.

A new method of auditing surgical mortality rates: application to a group of elderly general surgical patients.

In a prospective study of 505 patients aged 65 years or over admitted to a general surgical unit the overall hospital mortality rate was 14.5% and the postoperative mortality rate 12.0%. These rates fell to 3.6% and 5.8% respectively when deaths in non-viable patients were excluded from the analysis. An audit of surgical outcome that fails to identify non-viable patients is therefore potentially misleading. A standardised system of reporting surgical mortality is proposed to aid the comparison of results from different units. The key elements of this system are (a) the separation of the results from non-viable and potentially viable patients; (b) the consideration of both operative and non-operative mortality; (c) the differentiation between medical and surgical causes of postoperative mortality; and (d) the identification of patients who are discharged from the unit but who have residual malignancy. Data presented in such a way should be of direct relevance to surgeons and physicians who are seeking ways of improving the service provided for surgical patients of all ages.     

Randomised controlled trial and economic evaluation of a chest pain observation unit compared with routine care

Objectives To measure the effectiveness and cost effectiveness of providing care in a chest pain observation unit compared with routine care for patients with acute, undifferentiated chest pain.Design Cluster randomised controlled trial, with 442 days randomised to the chest pain observation unit or routine care, and cost effectiveness analysis from a health service costing perspective.Setting The emergency department at the Northern General Hospital, Sheffield, United Kingdom.Participants 972 patients with acute, undifferentiated chest pain (479 attending on days when care was delivered in the chest pain observation unit, 493 on days of routine care) followed up until six months after initial attendance.Main outcome measures The proportion of participants admitted to hospital, the proportion with acute coronary syndrome sent home inappropriately, major adverse cardiac events over six months, health utility, hospital reattendance and readmission, and costs per patient to the health service.Results Use of a chest pain observation unit reduced the proportion of patients admitted from 54% to 37% (difference 17%, odds ratio 0.50, 95% confidence interval 0.39 to 0.65, P < 0.001) and the proportion discharged with acute coronary syndrome from 14% to 6% (8%, -7% to 23%, P = 0.264). Rates of cardiac event were unchanged. Care in the chest pain observation unit was associated with improved health utility during follow up (0.0137 quality adjusted life years gained, 95% confidence interval 0.0030 to 0.0254, P = 0.022) and a saving of £78 per patient (-£56 to £210, P = 0.252).Conclusions Care in a chest pain observation unit can improve outcomes and may reduce costs to the health service. It seems to be more effective and more cost effective than routine care.     

A randomised prospective comparison of percutaneous endoscopic gastrostomy and nasogastric tube feeding after acute dysphagic stroke.

OBJECTIVE--To compare percutaneous endoscopic gastrostomy and nasogastric tube feeding after acute dysphagic stroke. DESIGN--Randomised prospective study of inpatients with acute stroke requiring enteral nutrition. SETTING--One university hospital (Nottingham) and one district general hospital (Derby). SUBJECTS--30 patients with persisting dysphagia at 14 days after acute stroke: 16 patients were randomised to gastrostomy tube feeding and 14 to nasogastric tube feeding. MAIN OUTCOME MEASURES--Six week mortality; amount of feed administered; change in nutritional state; treatment failure; and length of hospital stay. RESULTS--Mortality at 6 weeks was significantly lower in the gastrostomy group with two deaths (12%) compared with eight deaths (57%) in the nasogastric group (P < 0.05). All gastrostomy fed patients (16) received the total prescribed feed whereas 10/14 (71%) of nasogastric patients lost at least one day''s feed. Nasogastric patients received a significantly (P < 0.001) smaller proportion of their prescribed feed (78%; 95% confidence interval 63% to 94%) compared with the gastrostomy group (100%). Patients fed via a gastrostomy tube showed greater improvement in nutritional state, according to several different criteria at six weeks compared with the nasogastric group. In the gastrostomy group the mean albumin concentration increased from 27.1 g/l (24.5 g/l to 29.7 g/l) to 30.1 g/l (28.3 g/l to 31.9 g/l). In contrast, among the nasogastric group there was a reduction from 31.4 g/l (28.6 g/l to 34.2 g/l) to 22.3 g/l (20.7 g/l to 23.9 g/l) (P < 0.003). In addition, there were fewer treatment failures in the gastrostomy group (0/16 versus 3/14). Six patients from the gastrostomy group were discharged from hospital within six weeks of the procedure compared with none from the nasogastric group (P < 0.05). CONCLUSION--This study indicates that early gastrostomy tube feeding is greatly superior to nasogastric tube feeding and should be the nutritional treatment of choice for patients with acute dysphagic stroke.     

Geriatric medicine in Hull: a comprehensive service.

A partially age-related admission policy coupled with a "single-ward" scheme for treatment and rehabilitation was introduced by the Hull geriatric department in 1970. With rare exceptions, elderly patients needing hospital care have been admitted directly to the geriatric unit, and the proportion of the retired population admitted by the general physicians has been greatly reduced. The proportion of inpatients needing continuing care has been reduced to less than 20%, the mean length of inpatient stay has fallen to under 30 days, and separate long-stay wards are no longer needed. More than 91% of patients are admitted without preceding domiciliary assessment, and only 5-6% of admissions are transferred from other units within the area.     

Transfusion Patterns in All Patients Admitted to the Intensive Care Unit and in Those Who Die in Hospital: A Descriptive Analysis

While it is known that the use of health care resources increases at the end of life in patients admitted to the Intensive Care Unit (ICU), the allocation of blood products at the end of life has not been described. The objective of this study was to describe overall transfusion patterns in the ICU, and specifically in patients who die in hospital. We conducted a retrospective cohort study of adult patients admitted to the ICU of a university-affiliated hospital, who were discharged or died between November 1, 2006 and June 30, 2012. During the study period, 10,642 patients were admitted at least once to the ICU. Of these patients, 4079 (38.3%) received red blood cells (RBCs), plasma or platelets in the ICU. The ICU mortality rate was 28.1% and in-hospital mortality rate was 32.3%. Among 39,591 blood product units transfused over the course of the study in the ICU (18,144 RBC units, 16,920 plasma units and 4527 platelet units), 46.2% were administered to patients who later died within the same hospitalization (41.2% of RBCs, 50.4% of plasma and 50.8% of platelets). Of all blood product units (RBCs, plasma and platelets) administered in the ICU over the study period, 11% were given within the last 24 hours before death. A large proportion of blood products used in the ICU are administered to patients who ultimately succumb to their illness in hospital, and many of these blood units are given in close proximity to death.     

Erythropoietin therapy for acute stroke is both safe and beneficial

BACKGROUND: Erythropoietin (EPO) and its receptor play a major role in embryonic brain, are weakly expressed in normal postnatal/adult brain and up-regulated upon metabolic stress. EPO protects neurons from hypoxic/ ischemic injury. The objective of this trial is to study the safety and efficacy of recombinant human EPO (rhEPO) for treatment of ischemic stroke in man. MATERIALS AND METHODS: The trial consisted of a safety part and an efficacy part. In the safety study, 13 patients received rhEPO intravenously (3.3 X 10(4) IU/50 ml/30 min) once daily for the first 3 days after stroke. In the double-blind randomized proof-of-concept trial, 40 patients received either rhEPO or saline. Inclusion criteria were age <80 years, ischemic stroke within the middle cerebral artery territory confirmed by diffusion-weighted MRI, symptom onset <8 hr before drug administration, and deficits on stroke scales. The study endpoints were functional outcome at day 30 (Barthel Index, modified Rankin scale), NIH and Scandinavian stroke scales, evolution of infarct size (sequential MRI evaluation using diffusion-weighted [DWI] and fluid-attenuated inversion recovery sequences [FLAIR]) and the damage marker S100ss. RESULTS: No safety concerns were identified. Cerebrospinal fluid EPO increased to 60-100 times that of nontreated patients, proving that intravenously administered rhEPO reaches the brain. In the efficacy trial, patients received rhEPO within 5 hr of onset of symptoms (median, range 2:40-7:55). Admission neurologic scores and serum S100beta concentrations were strong predictors ofoutcome. Analysis of covariance controlled for these two variables indicated that rhEPO treatment was associated with an improvement in follow-up and outcome scales. A strong trend for reduction in infarct size in rhEPO patients as compared to controls was observed by MRI. CONCLUSION: Intravenous high-dose rhEPO is well tolerated in acute ischemic stroke and associated with an improvement in clinical outcome at 1 month. A larger scale clinical trial is warranted.     

Collaborative systematic review of the randomised trials of organised inpatient (stroke unit) care after stroke. Stroke Unit Trialists' Collaboration.

OBJECTIVES: To define the characteristics and determine the effectiveness of organised inpatient (stroke unit) care compared with conventional care in reducing death, dependency, and the requirement for long term institutional care after stroke. DESIGN: Systematic review of all randomised trials which compared organised inpatient stroke care with the contemporary conventional care. Specialist stroke unit interventions were defined as either a ward or team exclusively managing stroke (dedicated stroke unit) or a ward or team specialising in the management of disabling illnesses, which include stroke (mixed assessment/rehabilitation unit). Conventional care was usually provided in a general medical ward. SETTING: 19 trials (of which three had two treatment arms). 12 trials randomised a total of 2060 patients to a dedicated stroke unit or a general medical ward, six trials (647 patients) compared a mixed assessment/rehabilitation unit with a general medical ward, and four trials (542 patients) compared a dedicated stroke unit with a mixed assessment/rehabilitation unit. MAIN OUTCOME MEASURES: Death, institutionalisation, and dependency. RESULTS: Organised inpatient (stroke unit) care, when compared with conventional care, was best characterised by coordinated multidisciplinary rehabilitation, programmes of education and training in stroke, and specialisation of medical and nursing staff. The stroke unit care was usually housed in a geographically discrete ward. Stroke unit care was associated with a long term (median one year follow up) reduction of death (odds ratio 0.83, 95% confidence interval 0.69 to 0.98; P < 0.05) and of the combined poor outcomes of death or dependency (0.69, 0.59 to 0.82; P < 0.0001) and death or institutionalisation (0.75, 0.65 to 0.87; P < 0.0001). Beneficial effects were independent of patients'' age, sex, or stroke severity and of variations in stroke unit organisation. Length of stay in a hospital or institution was reduced by 8% (95% confidence interval 3% to 13%) compared with conventional care but there was considerable heterogeneity of results. CONCLUSIONS: Organised stroke unit care resulted in long term reductions in death, dependency, and the need for institutional care. The observed benefits were not restricted to any particular subgroup of patients or model of stroke unit care. No systematic increase in the use of resources (in terms of length of stay) was apparent.     

Effect of Beta-Blocker Therapy on the Risk of Infections and Death after Acute Stroke – A Historical Cohort Study

BackgroundInfections are a frequent cause for prolonged hospitalization and increased mortality after stroke. Recent studies revealed a stroke-induced depression of the peripheral immune system associated with an increased susceptibility for infections. In a mice model for stroke, this immunosuppressive effect was reversible after beta-blocker administration. The aim of our study was to investigate the effect of beta-blocker therapy on the risk of infections and death after stroke in humans.Methods625 consecutive patients with ischemic or hemorrhagic stroke, admitted to a university hospital stroke unit, were included in this historical cohort study. The effect of beta-blocker therapy on post-stroke pneumonia, urinary tract infections and death was investigated using multivariable Poisson and Cox regression models.Results553 (88.3%) patients were admitted with ischemic stroke, the remaining 72 (11.7%) had a hemorrhagic stroke. Median baseline NIHSS was 8 (IQR 5–16) points. 301 (48.2%) patients received beta-blocker therapy. There was no difference in the risk of post-stroke pneumonia between patients with and without beta-blocker therapy (Rate Ratio = 1.00, 95%CI 0.77–1.30, p = 0.995). Patients with beta-blocker therapy showed a decreased risk for urinary tract infections (RR = 0.65, 95%CI 0.43–0.98, p = 0.040). 7-days mortality did not differ between groups (Hazard Ratio = 1.36, 95%CI 0.65–2.77, p = 0.425), while patients with beta-blocker therapy showed a higher 30-days mortality (HR = 1.93, 95%CI 1.20–3.10, p = 0.006).ConclusionsBeta-blocker therapy did not reduce the risk for post-stroke pneumonia, but significantly reduced the risk for urinary tract infections. Different immune mechanisms underlying both diseases might explain these findings that need to be confirmed in future studies.     

Outcome and upper extremity function within 72 hours after first occasion of stroke in an unselected population at a stroke unit. A part of the SALGOT study

Background

Reduced upper extremity function is one of the most common impairments after stroke and has previously been reported in approximately 70-80% of patients in the acute stage. Acute care for stroke has changes over the last years, with more people being admitted to a stroke unit as well as use of thrombolysis. The aim of the present study was to describe baseline characteristics, care pathway and discharge status in an unselected group of patients with first occasion of stroke who were at a stroke unit within 72 hours after stroke and also to investigate the frequency of impaired arm and hand function. A second aim was to explore factors associated with impaired upper extremity function and the impact of impairment on the patient’s outcome.

Methods

Patients over 18 years of age with first ever stroke, living in a geographical catchment area, being at the stroke unit within 72 hours after onset, with no prior upper extremity impairment were included. Baseline characteristics, arm and hand function within 72 hours, stroke outcome and care pathway in the acute phase were described, by gathering information retrospectively from the patients’ charts. Ischemic strokes were categorized according to the Bamford classification and the Trial of Org 10172 in Acute Stroke Treatment criteria.

Results

Of the 969 patients with first ever stroke who were screened, 642 patients fulfilled the inclusion criteria. According to the National Institutes of Health Stroke Scale (NIHSS), the patients had a mean score of 6.0, median 3.0, at arrival to the hospital. Ischemic stroke was most frequent in the anterior circulation (87.7%). Within 72 hours after stroke onset 48.0% of the patients had impaired arm and hand function and this was positively associated with higher age (p?<?0.004), longer stay in the acute care (p?<?0.001) and mortality in acute care (p?<?0.001). Directly admitted to the stroke unit were 89.1% of the patients and 77.1% received hospital care on same day as stroke onset. Mean length of stay in the stroke unit was 9.9 days, 56.8% of the patients were discharged directly home from the stroke unit. Mortality within 72 hours after stroke onset was 5.0%.

Conclusion

Impaired arm and hand function is present in 48% of the patients in a non selected population with first ever stroke, estimated within 72 hours after onset. This is less than previously reported. Impaired arm and hand function early after stroke is associated with higher age, longer stay in the acute care, and higher mortality within the acute hospital care.

     

Patients with Acute Poisoning Seen in a General Medical Unit (1960-71)

A review of the 637 out of a total of 941 consecutive cases of acute poisoning admitted to an acute medical unit without special facilities for the treatment of poisoning has shown that despite considerable limitations in the medical, nursing, and laboratory facilities available the results compare favourably with those reported from specialized units.     

Survey of intensive care of severely head injured patients in the United Kingdom.

OBJECTIVES--To study practice in intensive care of patients with severe head injury in neurosurgical referral centres in United Kingdom. DESIGN--Structured telephone interview of senior nursing staff in intensive care unit of adult neurosurgical referral centre. SETTING--39 intensive care units in hospitals that accepted acute head injuries for specialist neurosurgical management, identified from Medical Directory and information from professional bodies. MAIN OUTCOME MEASURES--Details of organisation and administration of intensive care and patterns of monitoring and treatment for patients admitted with severe head injury. RESULTS--Patients were managed in specialist neurosurgical intensive care units in 21 of the centres and in general intensive care units in 18. Their intensive care was coordinated by an anaesthetist in 25 units and by a neurosurgeon in 12. Annual case-load varied between units: 20 received > 100 patients, 12 received 50-100, and seven received 25-49. Monitoring and treatment varied considerably between centres. Invasive arterial pressure monitoring was used routinely in 36 units, but central venous pressure monitoring was routinely used in 24 and intracranial pressure was routinely monitored in only 19. Corticosteroids were used to treat intracranial hypertension in 19 units. Seventeen units routinely aimed for arterial carbon dioxide pressure of 3.3-4.0 kPa, and one unit still used severe hyperventilation to a pressure of < 3.3 kPa. CONCLUSION--The intensive care of patients with acute head injuries varied widely between the centres surveyed. Rationalisation of the intensive care of severe head injury with the production of widely accepted guidelines ought to improve the quality of care.     

Magnetic resonance imaging with pathological correlation in a case of mantle cell lymphoma of the parotid gland: a case report

Introduction

Tetanus rarely occurs in developed countries, but it can result in fatal complications including respiratory failure due to generalized muscle spasms. Magnesium infusion has been used to treat spasticity in tetanus, and its effectiveness is supported by several case reports and a recent randomized controlled trial

Case presentations

Three Caucasian Greek men aged 30, 50 and 77 years old were diagnosed with tetanus and admitted to a general 12-bed intensive care unit in 2006 and 2007 for respiratory failure due to generalized spasticity. Intensive care unit treatment included antibiotics, hydration, enteral nutrition, early tracheostomy and mechanical ventilation. Intravenous magnesium therapy controlled spasticity without the need for additional muscle relaxants. Their medications were continued for up to 26 days, and adjusted as needed to control spasticity. Plasma magnesium levels, which were measured twice a day, remained in the 3 to 4.5 mmol/L range. We did not observe hemodynamic instability, arrhythmias or other complications related to magnesium therapy in these patients. All patients improved, came off mechanical ventilation, and were discharged from the intensive care unit in a stable condition.

Conclusion

In comparison with previous reports, our case series contributes the following meaningful additional information: intravenous magnesium therapy was used on patients already requiring mechanical ventilation and remained effective for up to 26 days (significantly longer than in previous reports) without significant toxicity in two patients. The overall outcome was good in all our patients. However, the optimal dose, optimal duration and maximum safe duration of intravenous magnesium therapy are unknown. Therefore, until more data on the safety and efficacy of magnesium therapy are available, its use should be limited to carefully selected tetanus cases.     

An Observational Study of Patient Characteristics Associated with the Mode of Admission to Acute Stroke Services in North East,England

Objective

Effective provision of urgent stroke care relies upon admission to hospital by emergency ambulance and may involve pre-hospital redirection. The proportion and characteristics of patients who do not arrive by emergency ambulance and their impact on service efficiency is unclear. To assist in the planning of regional stroke services we examined the volume, characteristics and prognosis of patients according to the mode of presentation to local services.

Study design and setting

A prospective regional database of consecutive acute stroke admissions was conducted in North East, England between 01/09/10-30/09/11. Case ascertainment and transport mode were checked against hospital coding and ambulance dispatch databases.

Results

Twelve acute stroke units contributed data for a mean of 10.7 months. 2792/3131 (89%) patients received a diagnosis of stroke within 24 hours of admission: 2002 arrivals by emergency ambulance; 538 by private transport or non-emergency ambulance; 252 unknown mode. Emergency ambulance patients were older (76 vs 69 years), more likely to be from institutional care (10% vs 1%) and experiencing total anterior circulation symptoms (27% vs 6%). Thrombolysis treatment was commoner following emergency admission (11% vs 4%). However patients attending without emergency ambulance had lower inpatient mortality (2% vs 18%), a lower rate of institutionalisation (1% vs 6%) and less need for daily carers (7% vs 16%). 149/155 (96%) of highly dependent patients were admitted by emergency ambulance, but none received thrombolysis.

Conclusion

Presentations of new stroke without emergency ambulance involvement were not unusual but were associated with a better outcome due to younger age, milder neurological impairment and lower levels of pre-stroke dependency. Most patients with a high level of pre-stroke dependency arrived by emergency ambulance but did not receive thrombolysis. It is important to be aware of easily identifiable demographic groups that differ in their potential to gain from different service configurations.
