A prospective before-and-after trial of a medical emergency team

OBJECTIVE: To determine the effect on cardiac arrests and overall hospital mortality of an intensive care-based medical emergency team. DESIGN AND SETTING: Prospective before-and-after trial in a tertiary referral hospital. PATIENTS: Consecutive patients admitted to hospital during a 4-month "before" period (May-August 1999) (n = 21 090) and a 4-month intervention period (November 2000 -February 2001) (n = 20 921). MAIN OUTCOME MEASURES: Number of cardiac arrests, number of patients dying after cardiac arrest, number of postcardiac-arrest bed-days and overall number of in-hospital deaths. RESULTS: There were 63 cardiac arrests in the "before" period and 22 in the intervention period (relative risk reduction, RRR: 65%; P < 0.001). Thirty-seven deaths were attributed to cardiac arrests in the "before" period and 16 in the intervention period (RRR: 56%; P = 0.005). Survivors of cardiac arrest in the "before" period required 163 ICU bed-days versus 33 in the intervention period (RRR: 80%; P < 0.001), and 1353 hospital bed-days versus 159 in the intervention period (RRR: 88%; P < 0.001). There were 302 deaths in the "before" period and 222 in the intervention period (RRR: 26%; P = 0.004). CONCLUSIONS: The incidence of in-hospital cardiac arrest and death following cardiac arrest, bed occupancy related to cardiac arrest, and overall in-hospital mortality decreased after introducing an intensive care-based medical emergency team.     

A multidisciplinary Care Coordination Team improves emergency department discharge planning practice

In response to difficulties meeting the demand for hospital services ("access block") at Royal Melbourne Hospital, a major metropolitan tertiary referral hospital, an audit of patient needs revealed a shortage of aged-care beds and a need for post-acute care. A multidisciplinary Care Coordination Team (CCT) was formed at the end of July 2000 to ensure that emergency department patients were provided with services that would facilitate their return to, or maintenance in, the community. The target population included the frail elderly, those living alone, the homeless, frequent emergency department attenders, and those with complex medical or drug and alcohol problems. As part of routine emergency department care, a risk screen was implemented to determine referral to the CCT. In the first 12 months, the CCT saw 2532 patients (5.8% of all emergency department attendances). Nearly half of these patients were discharged home with referrals to community service providers. The rate of hospital admission from the emergency department fell significantly compared with the 12-month period before implementation of the CCT (13 420 patients, 30.9% [95% CI, 30.5-31.3] v 14 217 patients, 32.6% [95% CI, 32.2-33.0]; P < 0.001). Surveys of staff, patients and carers, as well as community service providers, showed a high level of satisfaction with the CCT.     

Effect of a community intervention on patient delay and emergency medical service use in acute coronary heart disease: The Rapid Early Action for Coronary Treatment (REACT) Trial

CONTEXT: Delayed access to medical care in patients with acute myocardial infarction (AMI) is common and increases myocardial damage and mortality. OBJECTIVE: To evaluate a community intervention to reduce patient delay from symptom onset to hospital presentation and increase emergency medical service (EMS) use. DESIGN AND SETTING: The Rapid Early Action for Coronary Treatment Trial, a randomized trial conducted from 1995 to 1997 in 20 US cities (10 matched pairs; population range, 55,777-238,912) in 10 states. PARTICIPANTS: A total of 59,944 adults aged 30 years or older presenting to hospital emergency departments (EDs) with chest pain, of whom 20,364 met the primary population criteria of suspected acute coronary heart disease on admission and were discharged with a coronary heart disease-related diagnosis. INTERVENTION: One city in each pair was randomly assigned to an 18-month intervention that targeted mass media, community organizations, and professional, public, and patient education to increase appropriate patient actions for AMI symptoms (primary population, n=10,563). The other city in each pair was randomly assigned to reference status (primary population, n=9801). MAIN OUTCOME MEASURES: Time from symptom onset to ED arrival and EMS use, compared between intervention and reference city pairs. RESULTS: General population surveys provided evidence of increased public awareness and knowledge of program messages. Patient delay from symptom onset to hospital arrival at baseline (median, 140 minutes) was identical in the intervention and reference communities. Delay time decreased in intervention communities by -4.7% per year (95% confidence interval [CI], -8.6% to -0.6%), but the change did not differ significantly from that observed in reference communities (-6. 8% per year; 95% CI, -14.5% to 1.6%; P=.54). EMS use by the primary study population increased significantly in intervention communities compared with reference communities, with a net effect of 20% (95% CI, 7%-34%; P<.005). Total numbers of ED presentations for chest pain and patients with chest pain discharged from the ED, as well as EMS use among patients with chest pain released from the ED, did not change significantly. CONCLUSIONS: In this study, despite an 18-month intervention, time from symptom onset to hospital arrival for patients with chest pain did not change differentially between groups, although increased appropriate EMS use occurred in intervention communities. New strategies are needed if delay time from symptom onset to hospital presentation is to be decreased further in patients with suspected AMI. JAMA. 2000;284:60-67     

Detecting and reducing hospital adverse events: outcomes of the Wimmera clinical risk management program

OBJECTIVES: To determine if an integrated clinical risk management program that detects adverse patient events in a hospital, analyses their risk and takes action can alter the rate of adverse events. DESIGN: Longitudinal survey of adverse patient events over eight years of progressive implementation of the risk management program. PARTICIPANTS AND SETTING: 49,834 inpatients (July 1991 to September 1999) and 20,050 emergency department patients (October 1997 to September 1999) at a rural base hospital in the Wimmera region of Victoria. MAIN OUTCOME MEASURES: Rates of adverse events detected by medical record review and clinical incident and general practitioner reporting. RESULTS: The annual rate of inpatient adverse events decreased between the first and eighth years of the study from 1.35% of all patient discharges (69 events) to 0.74% (49 events) (P<0.001). Absolute risk reduction was 0.61% (95% CI, 0.23%-0.99%), and relative risk reduction was 44.9% (95% CI, 16.9%-72.9%). The quarterly rate of emergency department adverse events decreased between the first and eighth quarters of monitoring from 3.26% of all attendances (84 events) to 0.48% (12 events) (P< 0.001). Absolute risk reduction was 2.78% (95% CI, 2.04%-3.52%), and relative risk reduction was 85.3% (95% CI, 62.7%-100%). CONCLUSIONS: Adverse patient events can be detected, and their frequency reduced, using multiple detection methods and clinical improvement strategies as part of an integrated clinical risk management program.     

The effects of quality improvement interventions on inhospital mortality after acute myocardial infarction.

OBJECTIVE: To evaluate the effects of quality improvement interventions on inhospital mortality after admission for acute myocardial infarction (AMI). DESIGN: Before-and-after study (with concurrent controls) based on hospital discharge data from a routinely maintained, administrative database. SETTING: All Queensland public hospitals, July 1991 - June 1999. STUDY POPULATION: Patients with AMI admitted through the emergency department. Intervention: Development and promulgation of clinical practice guidelines at one hospital, combined with regular audit and feedback, commencing November 1995. MAIN OUTCOME MEASURES: Inhospital mortality (adjusted for age, sex and comorbidities) for four-year periods before (1991-92 to 1994-95) and after (1995-96 to 1998-99) initiation of quality improvement interventions. RESULTS: Before the intervention, the adjusted odds ratio (OR) for inhospital death at the intervention hospital was about the same as at other public hospitals (adjusted OR, 0.99; 95% CI, 0.80-1.24), but was more than 40% lower after the intervention (adjusted OR, 0.59; 95% Cl, 0.45-0.78). After the intervention, the risk of death at the intervention hospital was lower compared with hospitals with cardiologists as admitting practitioners (adjusted OR, 0.63; 95% CI, 0.48-0.83), with onsite revascularisation facilities (adjusted OR, 0.66; 95% CI, 0.49-0.88), and with large numbers (> or = 250 per year) of annual admissions of patients with AMI (adjusted OR, 0.72; 95% CI, 0.54-0.97). CONCLUSIONS: Quality improvement interventions lower the risk of inhospital death in patients with AMI. Implementation of such interventions in all hospitals may confer a risk of death lower than that achieved by admitting all patients under the care of cardiologists, or to hospitals with revascularisation facilities or a high volume of admissions of patients with AMI.     

The effect of resident peer-to-peer education on compliance with urinary catheter placement indications in the emergency department

OBJECTIVE This study aims to evaluate the effect of resident peer-to-peer education on knowledge of appropriate urinary catheter (UC) placement in the emergency department (ED) and to determine if this translates into further reduction in UC utilisation. Background Instituting guidelines for appropriate UC placement reduces UC utilisation in the ED. No study has explored if resident education in a teaching hospital would further reduce UC utilisation. METHODS An educational intervention implemented in February 2009 consisted of a lecture, distribution of pocket cards and a peer-administered weekly review of institutional UC guidelines. A 12-question multiple-choice test was given to residents prelecture and postlecture, and the 12-question test was repeated 3 months later. Retrospective chart review was performed to evaluate UC utilisation before, immediately after and 3 months after the educational intervention. RESULTS 30 residents completed all three tests. Significant differences were found between the mean test score pre-education and the mean test score immediately after education (9.43±1.17 vs 10.87±1.46, p<0.001) and between the mean test score pre-education and the mean test score 3 months posteducation (9.43±1.17 vs 10.43±1.28, p<0.001). There was no significant difference in UC utilisation or in the proportion of indicated UCs placed by residents within the three study periods. CONCLUSIONS Resident peer-to-peer education was associated with improvement of knowledge but did not result in decreased UC utilisation. A more active approach must be taken and other factors need to be further explored to reduce unnecessary placement of UC by residents in the ED.     

Effect of community-based interventions on high-risk drinking and alcohol-related injuries

CONTEXT: High-risk alcohol consumption patterns, such as binge drinking and drinking before driving, and underage drinking may be linked to traffic crashes and violent assaults in community settings. OBJECTIVES: To determine the effect of community-based environmental interventions in reducing the rate of high-risk drinking and alcohol-related motor vehicle injuries and assaults. DESIGN AND SETTING: A longitudinal multiple time series of 3 matched intervention communities (northern California, southern California, and South Carolina) conducted from April 1992 to December 1996. Outcomes were assessed by 120 general population telephone surveys per month of randomly selected individuals in the intervention and comparison sites, traffic data on motor vehicle crashes, and emergency department surveys in 1 intervention-comparison pair and 1 additional intervention site. INTERVENTIONS: Mobilize the community; encourage responsible beverage service; reduce underage drinking by limiting access to alcohol; increase local enforcement of drinking and driving laws; and limit access to alcohol by using zoning. MAIN OUTCOME MEASURES: Self-reported alcohol consumption and driving after drinking; rates of alcohol-related crashes and assault injuries observed in emergency departments and admitted to hospitals. RESULTS: Population surveys revealed that the self-reported amount of alcohol consumed per drinking occasion declined 6% from 1.37 to 1. 29 drinks. Self-reported rate of "having had too much to drink" declined 49% from 0.43 to 0.22 times per 6-month period. Self-reported driving when "over the legal limit" was 51% lower (0. 77 vs 0.38 times) per 6-month period in the intervention communities relative to the comparison communities. Traffic data revealed that, in the intervention vs comparison communities, nighttime injury crashes declined by 10% and crashes in which the driver had been drinking declined by 6%. Assault injuries observed in emergency departments declined by 43% in the intervention communities vs the comparison communities, and all hospitalized assault injuries declined by 2%. CONCLUSION: A coordinated, comprehensive, community-based intervention can reduce high-risk alcohol consumption and alcohol-related injuries resulting from motor vehicle crashes and assaults.

Serum sodium valproate testing: is it appropriate?

OBJECTIVE: To assess whether serum sodium valproate (SVP) testing in the hospital setting is being performed according to evidence-based criteria. DESIGN AND SETTING: Retrospective audit of serum SVP concentration measurements performed on inpatients and emergency department patients at The Canberra Hospital from May to July 2005. MAIN OUTCOME MEASURES: Indication for performing the test, assessed against evidence-based criteria; timing of blood sample collection; whether the test result altered patient management; whether the request form allowed laboratory staff to assess the appropriateness of the test; cost of performing inappropriate tests. RESULTS: We retrieved 211 test results performed on a total of 95 patients. Notes on 89 patients were available for analysis. Based on evidence-based criteria, 15% of tests were done for an appropriate indication and 29% of the samples were taken at an appropriate time. At most (using generous criteria), 57% of test results made a difference to patient management. Forty-four per cent of request forms contained sufficient detail to allow the pathology department to assess the appropriateness of the test. An estimated $13 236 would be spent unnecessarily on SVP testing at our hospital over a 1-year period. CONCLUSIONS: Most serum SVP level measurements were requested inappropriately, and many were not taken at the correct time, thereby rendering the results uninterpretable. Better education of requesting clinicians could significantly reduce the number of unnecessary tests and thus reduce the cost to the health service.     

Analysis of blood tests in the emergency department of a tertiary care hospital

There is ample evidence that many investigations sent from the accident and emergency department are inappropriate, thus affecting the quality of patient care. A study was designed to address this issue in the emergency department of a tertiary care hospital of a large city. A prospective cross-sectional study was carried out during the 3-month period 1 December 1996 to 28 February 1997. A set of guidelines was used to assess the appropriateness of different blood tests for the initial assessment of the patients presenting with common clinical conditions, although any investigation could be done if considered important for patient management. All other blood tests were considered inappropriate. A total of 6401 patients were seen in the emergency department and 14,300 blood tests were done on 3529 patients with diagnoses covered by the guidelines. Of these 62.2% were found to be inappropriate. Of the total 22,655 investigations done on all the 6401 patients seen, only 3.8% influenced the diagnosis, 3.0% influenced patient care in the emergency department, and 4.0% influenced the decision to admit or not. Amylase and arterial blood gases were found to be the most appropriate investigations. Analysis of reasons for unnecessary use of emergency tests suggested that improving supervision, decreasing the utilization of the emergency department as a phlebotomy service for the hospital, and abolition of routine blood tests would help to improve patient care.     

The financial effects of emergency department-generated admissions under prospective payment systems

The purpose of this study was to assess the financial impact (revenues vs expenses) as measured by hospital charges and costs vs diagnosis-related group (DRG) revenues of prospective payment systems on emergency department-generated admissions for a large teaching hospital under two payment systems: Medicare and an all-payor system. All emergency department admissions were analyzed for the years 1983 (N = 4,273) and 1984 (N = 4,125) under both systems, using standard DRG methodology. Our findings were as follows: (1) With charges as a measure of expense under both payment schemes, all clinical departments had large groups of unprofitable patients: Medicare, $12,895,038; all-payor system, $15,553,893. (2) When costs were computed as the expense measure (using our hospital's cost-to-charge ratio), Medicare patients produced a deficit ($2,363,163); however, under an all-payor system there was a small net profit ($4,267,859). (3) The implementation of federalized DRG reimbursement rates increased our losses for this population from 1983 to 1984. (4) Reductions in outlier reimbursement (10%) and teaching costs (25%) caused our revenues to drop substantially, potentiating our losses. These findings suggest that hospitals with large emergency department admission populations, particularly Medicare patients, may be at a significant financial disadvantage under prospective payment systems.     

The effects of bonus payments on emergency service performance in Victoria.

OBJECTIVES: To review and analyse the system effects of the Emergency Service Enhancement Program (ESEP): bonus payments made to public hospitals to improve access to care for patients attending emergency departments. DESIGN: A review of the first 3 years' performance data, obtained from the Victorian Emergency Department Minimum Dataset (VEMD). SETTING: 21 public hospital emergency departments in Victoria, Australia (population 4.5 million), with about 700,000 patient attendances per year. The ESEP began in April 1995. MAIN OUTCOME MEASURES: The ESEP indicators of emergency department and inpatient bed access: occasions of "ambulance bypass" (emergency department unable to accept patients arriving by ambulance); emergency waiting times for Category 1, 2 and 3 patients (National Triage Scale) compared with agreed national performance thresholds; and "access block" (> 12 hours' waiting time in the emergency department before admission to hospital). RESULTS: The number of occasions of ambulance bypass per quarter decreased from 600 in 1994 to fewer than 100 in 1997 (P < 0.001). Despite an increased proportion of patient encounters in triage categories 1, 2 and 3 (31% v. 23%), zero waiting times for Category 1 patients were consistently adhered to, and adherence to waiting time thresholds for Category 2 and 3 patients improved significantly (P < 0.001, R2 = 0.74; and P < 0.035, R2 = 0.37, respectively), particularly for Category 2 patients. The number of patients waiting longer than 12 hours in emergency departments decreased non-significantly (P = 0.3, R2 = 0.1). CONCLUSION: Our results show that the ESEP has produced sustained improvements in all the indicators linked with bonus payments.     

Back for more: a qualitative study of emergency department reattendance for asthma

OBJECTIVE: To explore the reasons why individuals recurrently present with asthma to hospital emergency departments. DESIGN: A predominantly qualitative study in which participants were interviewed in-depth about their asthma. Data on medication use, respiratory health and asthma knowledge were also collected, and asthma severity was determined from medical records. SETTING: A tertiary teaching hospital and a suburban hospital emergency department (ED) from 1 March to 30 April 2000, and a rural hospital ED from 1 July to 31 August 2000. PARTICIPANTS: The participation rate was 32% of an initial 195 ED attendees (183 of whom were eligible) aged 18-70 years: 32 had presented to an ED for asthma care on more than one occasion over the preceding 12 months (reattendees), and 29 were non-reattendees. RESULTS: Two-thirds (22/32) of reattendees had chronic severe asthma and presentation to ED was deemed appropriate for 18 of these, indicated by recurrent severe asthma attacks despite seeking prior medical intervention. Reasons for re-presentation identified in a third of all reattendees included poor asthma knowledge, and financial and other barriers to medication use. CONCLUSIONS: We identified potentially preventable issues in about a third of patients (most of whom had mild to moderate asthma) who recurrently presented to EDs for treatment. The remainder of the participants sought emergency asthma treatment appropriately after failing to respond to medical care, and this was frequently in accordance with their asthma management plans.     

The effect of multidisciplinary case management on selected outcomes for frequent attenders at an emergency department

OBJECTIVE: To evaluate the effects of multidisciplinary case management (CM) on emergency department (ED) utilisation and psychosocial variables for frequent attenders at the ED. DESIGN: Retrospective cohort analysis, with the study population as historical controls and data analysed 12 months before and after CM intervention in the period 1 January 2000 - 31 December 2004. Subgroup analyses were performed according to primary problem categories: general medical, drug and alcohol, and psychosocial. SETTING: Inner urban tertiary hospital ED. PARTICIPANTS: Frequent ED attenders who received CM. MAIN OUTCOME MEASURES: ED attendances: length of stay, triage category, ambulance transport, disposition, attendances at the only two EDs nearby. Psychosocial factors: housing status, drug and alcohol use, and primary and community care engagement. RESULTS: 60 CM patients attended the ED on 1387 occasions. Total attendances increased after CM for the whole group (610 v 777, P = 0.055). Mean average length of stay (minutes) of the total study population and each subgroup was unaffected by CM (297 v 300, P = 0.8). Admissions for ED overnight observation increased as a result of CM (P = 0.025). CM increased scores for housing stability (P = 0.007), primary care linkage (P = 0.003), and community care engagement (P < 0.001) for the whole group and variously within subgroups. Drug and alcohol use was unaffected by CM. CONCLUSION: ED-initiated, multidisciplinary CM appears to increase ED utilisation and have a positive effect on some psychosocial factors for frequent attenders. A trend towards increased ED attendance and utilisation with CM may have implications for policies that seek to divert frequent attenders away from hospitals.     

Sudden unexpected death in the emergency department: caring for the survivors.

OBJECTIVE: To determine whether emergency department staff met the needs of the next of kin and close friends ("survivors") of patients dying in an emergency department and to assess the effectiveness of a program to improve care of survivors. DESIGN: Mail survey before and after program implementation. SETTING: Emergency department of a tertiary care, adult teaching hospital. PARTICIPANTS: Two groups of survivors, identified through a review of emergency department records of deaths during two 6-month periods. In the first group, surveyed in 1987, before program implementation, 26 (53%) of 49 responded; in the second group, surveyed in 1990, after program implementation, 40 (70%) of 57 responded. INTERVENTIONS: A structured, multidisciplinary protocol for notifying next of kin of death and supporting the survivors was implemented. An educational program was provided to all emergency department staff. An information pamphlet was created and provided to survivors. MAIN OUTCOME MEASURES: Questionnaire responses regarding the adequacy and timeliness of information provided, the support and actions by emergency department staff and the survivors' desire to be present during resuscitation efforts. RESULTS: Comparison of responses before and after program implementation showed that adequate information was provided before notification of death in 32% and 83% of cases respectively (p < 0.001), lengthy delays in receiving medical information occurred in 60% and 15% of cases (p < 0.01), adequate medical information concerning the events of death was provided in 53% and 88% (p < 0.05), the presence of emergency department staff was sufficient in 40% and 79% (p < 0.01), survivors spent less than 2 hours in the emergency department in 50% and 81% (p < 0.05), and survivors expressed a desire to be present during resuscitation efforts in 95% and 11% of cases (p < 0.001). CONCLUSION: The grievous experience of learning that a loved one has suddenly and unexpectedly died in the emergency department can be alleviated somewhat by a structured, multidisciplinary approach combined with staff sensitization and education.     

Improving access to acute stroke therapies: a controlled trial of organised pre-hospital and emergency care

OBJECTIVE: To assess the effectiveness of the PAST (Pre-hospital Acute Stroke Triage) protocol in reducing pre-hospital and emergency department (ED) delays to patients receiving organised acute stroke care, thereby increasing access to thrombolytic therapy. DESIGN: Prospective cohort study using historical controls. SETTING: Hunter Region of New South Wales, September 2005 to March 2006 (pre-intervention) and September 2006 to March 2007 (post-intervention). PARTICIPANTS: Consecutive patients presenting with acute stroke to a regional, tertiary referral hospital. INTERVENTION: PAST protocol, comprising a pre-hospital stroke assessment tool for ambulance officers, an ambulance protocol for hospital bypass for potentially thrombolysis-eligible patients, and pre-hospital notification of the acute stroke team. MAIN OUTCOME MEASURES: Proportion of patients who received intravenous tissue plasminogen activator (tPA), process of care time points (symptom onset to ED arrival, ED arrival to tPA treatment, and ED transit time), and clinical outcomes of patients treated with tPA. RESULTS: The proportion of ischaemic stroke patients treated with tPA increased from 4.7% (pre-intervention) to 21.4% (post-intervention) (P < 0.001). Time point outcomes also improved, with a reduction in median times from symptom onset to ED arrival from 150 to 90.5 min (P = 0.004) and from ED arrival to stroke unit admission from 361 to 232.5 minutes (P < 0.001). Of those treated with tPA, 43% had minimal or no disability at 3 months. CONCLUSIONS: Organised pre-hospital and ED acute stroke care increases patient access to tPA treatment, which is proven to reduce stroke-related disability.     

Review of US medical school finances, 1998-1999

Based on data from the Annual Medical School Questionnaire of the Liaison Committee on Medical Education, to which 100% of the 125 accredited allopathic US medical schools responded, we found that revenue supporting programs and activities of the 125 accredited medical schools in the United States totaled $39,761 million in 1998-1999. Three sources accounted for 79.3% of total revenues: practice plans ($13,724 million; 34.5%), grants and contracts ($11, 982 million; 30.1%), and hospital support ($5814 million; 14.6%). In the aggregate, total revenues increased by 7.4% between 1997-1998 and 1998-1999, a consequence at least in part due to a 2.9% increase in the number of full-time faculty. The largest increase in dollar amount came from grants and contracts ($1101 million; 10.2% increase). Revenue increases were not evenly distributed across the schools. Increases of 10% or more in key revenue sources-practice plans and hospital support-were reported by approximately one fourth of all schools. Another one fourth reported decreases in these same sources. JAMA. 2000;284:1127-1129     

Characteristics and outcomes of older patients presenting to the emergency department after a fall: a retrospective analysis

OBJECTIVES: To study older patients presenting to the emergency department after a fall--factors associated with the fall, injuries sustained and outcome. DESIGN: A retrospective analysis using the Emergency Department Information System (EDIS), the Trauma Registry and the patient information database (CCIS), in addition to the patient's emergency and inpatient medical records. SETTING: Emergency department of a major inner city teaching hospital, 1 June-30 November 1997. PATIENTS: All patients over 65 years presenting to the emergency department (ED) after a fall, for whom complete medical records were available. RESULTS: Of 803 patients over 65 years presenting to the ED after a fall, complete records were available for 733 (91.3%) (283 men and 450 women). Extrinsic (accidental) causes were implicated in more than a third of falls (313 patients [42.7%]). A high proportion of the patients were living at home (520; 70.9%) and walking unaided (389; 53.1%). Although absolute numbers of women increased with age, men were as likely as women to present after a fall. Many patients had fallen before--39% of the men (111/283) and 24% of the women (110/450). In 78 patients (10.6%), alcohol misuse may have been a direct cause of the fall. The overall injury rate was 70.5% (517/733 patients), the most common injury being an isolated fracture (269/517 patients; 52.0%). In all, 419 patients (57.2%) were admitted to hospital, 48% (200/419) with a fracture and 52% (219/419) for investigation of the medical cause of the fall. The median length of hospital stay was 6 days (mean, 10.4 days; range, 1-129 days); 35% (146/419) of patients were in hospital for more than 10 days. CONCLUSION: Older patients presenting to the ED after a fall had high injury rates, high admission rates and often prolonged hospitalisation. About a third had fallen before. Patients at risk can be identified in the ED and referred to falls prevention programs.     

Problem drinking in emergency department patients: the scope for early intervention

OBJECTIVE: To determine the prevalence of previously undiagnosed problem drinking and thereby to assess the suitability of the emergency department for early intervention. DESIGN: Three hundred and fifty ambulatory care patients were assessed by means of a structured interview schedule, physical examination and blood tests. Alcohol intake and presence of alcohol-related problems were recorded, along with history of past advice on drinking and self-perception of an alcohol problem. SETTING: The ambulatory care section of the emergency department of Royal Prince Alfred Hospital, Sydney. PATIENTS: Three hundred and fifty subjects, aged between 18 and 55 years, were sequentially selected over an 18-month period. RESULTS: Forty-one per cent of subjects (95% confidence interval, 36%-46%), 50% of men and 26% of women, were classified as problem drinkers on the basis of hazardous or harmful levels of alcohol consumption, frequent drinking to intoxication, evidence of dependence, or experience of alcohol-related problems. Of these, 63% had not previously received advice on drinking from a health professional and only 28% perceived they had a problem. Of particular note was that 24% of men and 4% of women were drinking 12 or more drinks (120 g of alcohol or more) in a single session on a weekly or more frequent basis. CONCLUSIONS: Many of the problem drinkers attending the emergency department have not previously received advice about their drinking from a health professional. The emergency department therefore offers considerable potential as a site for early detection and intervention in patients with hazardous and harmful alcohol use and related disorders.     

Time to hospital admission for acute stroke: an observational study

OBJECTIVES: To determine the time from symptom onset to hospital admission of patients with suspected acute stroke, final diagnoses and patient eligibility for thrombolytic therapy. DESIGN: Hospital-based, prospective, observational study. SETTING: Royal Adelaide Hospital Stroke Unit, South Australia. PATIENTS: All patients admitted to the unit with suspected acute stroke over 11 months (11 April to 10 October 2000 and 20 August 2001 to 19 January 2002). MAIN OUTCOME MEASURES: Time from symptom onset to admission; final diagnosis. RESULTS: Of 284 patients admitted, 39 (14%) had diagnoses other than stroke (including eight with transient ischaemic attacks), 42 (15%) had haemorrhagic stroke and 203 (71%) had ischaemic stroke. Median time to admission after symptom onset was 6 hours (range, 30 min to 13 days), with 100 patients admitted within 3 hours of symptom onset (35%), and 80 within 2 hours (28%). Thirty-seven patients (13%) could have been considered for thrombolysis (diagnosis of non-severe but disabling ischaemic stroke and admission time < 3 hours). Location at stroke onset was the only independent predictor of time to admission. CONCLUSIONS: Most patients with stroke do not present urgently to the emergency department, rendering them less likely to be considered for thrombolytic therapy.
