Pharmacy provision of emergency contraception: the Ontario emergency contraception pilot project.

OBJECTIVES: To develop and evaluate a program to provide emergency contraception (EC) directly in pharmacies that would recruit and train pharmacists and physician partners, and inform women about the availability of EC in pharmacies. METHODS: Pharmacists and physicians working in the Scarborough, Rexdale, and North York regions of Toronto were recruited to receive a training program on EC. The pharmacists in each pharmacy were linked with a designated physician who retrospectively authorized prescriptions provided under the protocol. Client eligibility for EC was determined using a self-administered questionnaire that was reviewed by the pharmacist. A poster and radio campaign advertised the service, and a telephone hotline informed users of their nearest participating pharmacy. Data on the client's age, reasons for requesting EC, time elapsed from intercourse until presentation, and requests for follow-up referral were analyzed using descriptive methodology. User satisfaction was determined through a mail-back questionnaire. RESULTS: A total of 146 pharmacists practising in 40 pharmacies were linked with 34 physicians. In the 1 year of the project, 6931 prescriptions for EC were provided. Fifty-four percent of the women accessed EC within 24 hours of intercourse. The majority of women were very satisfied with the service, and 21.1% indicated that had they not obtained EC in this way, they would not have obtained it elsewhere. More information about birth control was desired by 10.2% of the women. CONCLUSION: Direct pharmacist provision of EC is an effective pregnancy-prevention strategy that is well accepted by the women who access it.

[Malaria in the emergency room. Results of the emergency treatment of 137 patients with symptomatic malaria].

OBJECTIVE: To assess characteristics and outcome of emergency patients with acute malaria. PATIENTS AND METHODS: We retrospectively assessed the clinical and laboratory parameters of 137 consecutive patients (87 males, 50 females; median age 37 years, range 17 - 67 years) presenting with acute malaria to our tertiary care center between 1992 and 2002. RESULTS: Falciparum malaria was diagnosed in 116/137 and tertian malaria in 19/137 patients; a single patient was infected with both parasites while in another case the type of parasite remained unclear. Infections were acquired in Africa (121), Asia , and in the Americas . One traveler visited multiple continents. Only 36 % (50/137) of patients had used malaria chemoprophylaxis. 128/137 patients were treated as in-patients; 22 of these had to be treated on an intensive care unit. According to the criteria of the German Society of Tropical Medicine, 44/137 (32 %; 95 % confidence interval (CI): 25 - 40 %) patients suffered from complicated malaria. The overall mortality rate was 2/137 (1.5 %; 95 % CI: 0,4 - 5.2 %); the mortality rate of complicated malaria tropica was 2/44 (4,5 %; 95 % CI 1,3 - 15 %). Patients with complicated malaria were significantly older than those with uncomplicated malaria. Median length of hospital stay was 4 days in uncomplicated and 9 days in complicated cases. Based on costs of EUR 2500 per case, an attack rate of > 3 % in East African travelers and a cost of EUR 55 for a chemoprophylaxis with mefloquine, chemoprophylaxis is cost-effective. CONCLUSION: In our retrospective analysis, complicated malaria tropica was associated with older age. Although malaria causes considerable morbidity, the overall mortality from severe malaria is low. Reinforcement of chemoprophylaxis especially in travelers to Africa could reduce malaria cases and is cost-effective.

Managed care gatekeeping, emergency medicine coding, and insurance reimbursement outcomes for 980 emergency department visits from four states nationwide.

STUDY OBJECTIVE: We analyzed 980 emergency department visits for 951 patients with managed care insurance to document gatekeeping interactions and compare ED coding with professional fee billing reimbursements. METHODS: A prospective cohort study was performed at 12 academic and community hospital EDs in 4 states involving consecutive ED patients with managed care insurance. The main outcomes measured were gatekeeper decisions, coding levels, and reimbursement. RESULTS: Preauthorization for payment was required from managed care gatekeepers for 876 (89%) patients. Authorization was granted for 490 (56%) of these visits and denied in 176 (20%) visits; gatekeepers were not available for 210 (24%) visits. Reimbursement was initially denied for 211 (43%) of the ED visits preapproved by managed care gatekeepers. Reimbursement was initially denied for most (634 or 65%) visits, and downcoding occurred in the other 346 (35%) visits. Appeals for 560 (57%) visits resulted in a decrease in the number of unreimbursed ED visits to 193 and an increase in the number of reimbursed ED visits to 787. CONCLUSION: Preauthorization gatekeeping is not predictive of whether managed care third-party payers will initially reimburse ED visits. Overall, almost two thirds of all ED claims were initially denied, and reimbursed claims were uniformly downcoded. On appeal, reimbursement was often reinstated or increased, although billing services only appealed about half of ED visits.

Evidence-based emergency medicine/skills for evidence-based emergency care. Interval likelihood ratios: another advantage for the evidence-based diagnostician.

Emergency physicians are often confronted with making diagnostic decisions on the basis of a test result represented on a continuous scale. When the results of continuous data are expressed as binary outcomes using a single cutoff, loss of information and distortion may occur. In this setting, interval likelihood ratios provide a distinct advantage in interpretation over those based on a dichotomized sensitivity and specificity. Dividing the data into intervals uses more of the information contained in the data and allows the clinician to more appropriately interpret the test results and to make valid clinical decisions. This article illustrates the advantages of interval likelihood ratios with examples and demonstrates how to calculate them on the basis of different data formats. Authors and journals need to be encouraged to report the results of studies of performance of diagnostic tests using interval ranges rather than simple dichotomization when the tests involve continuous variables.

Trends in human immunodeficiency virus (HIV) infection among a patient population of an inner-city emergency department: implications for emergency department-based screening programs for HIV infection.

Personnel of inner-city emergency departments (EDs), which are frequently the only source of medical care for many patients, may be in a unique position to detect human immunodeficiency virus (HIV) infection earlier than personnel at other recommended screening sites. To assist development of ED-based screening strategies for HIV infection, we undertook a serosurvey of HIV infection in adult patients attending an ED during a 6-week period in 1992 using an identity-unlinked technique and compared our findings with data collected similarly in 1988. Of 1,606 patients, 183 (11.4%) were HIV-positive, compared with 6.0% in 1988. Seroprevalence rates of HIV infection among patients only at risk of heterosexual transmission increased more than fourfold (7% to 30.3%). CD4+ cell counts were higher in those patients with undiagnosed HIV infection than in those with known HIV infection. Targeting minority patients aged 25-44 years, intravenous drug users, and those patients at heterosexual risk would have identified 87% of patients with new HIV infection, while requiring screening of 41% of the study sample. Targeted voluntary screening programs in certain EDs would likely detect significant numbers of new early HIV infections.

Emergency treatment of bronchospastic attacks in an emergency medicine department: effects of a quality improvement project.

New insights have recently changed the therapeutical approach to bronchospastic attack (BA). In this paper we present the results of a quality assurance study devised to: (1) verify the extent to which these new insights are put into practice in our Emergency Medicine Department (EMD); (2) evaluate changes in EMD medical staff behaviour faced with BA after discussion and distribution of medical practice guidelines on the treatment of BA (a document produced by a group of experts in pulmonary medicine working in the EMD on the basis of current literature and personal experiences); (3) assess the impact of such guidelines on quality care. A retrospective analysis demonstrated an incorrect treatment of BA in the EMD. After the introduction of the guidelines we observed: (1) an improvement in physician behaviour that completely agreed with guidelines in 56% of instances after discussion and distribution of the document, in 8% before; (2) an improvement in the outcome of patients treated for BA in the EMD (13 versus 36% relapses for patients treated in the EMD and discharged).

Emergency department information: does it effect patients' perception and satisfaction about the care given in an emergency department?

The aim of this study was to find out if informing the patients about the facts of an emergency department (ED) on arrival influences their behaviour and satisfaction about the care given in the ED. For 5 days an information form was distributed on arrival to all patients visiting the ED and a questionnaire directed at all patients when leaving the ED. For a former 3 days the same questionnaire directed at the patients was distributed without giving them the information form. This form contained information about how the ED functions, how long and why the patients wait, and which patients are taken care of first. The patients who were not given the information form served as the control group; the patients who were given an information form but did not read it were also included in the same control group. Questionnaires of the informed group and the control group were compared. A total of 397 patients were given a questionnaire; 288 of them were given an information form and 109 did not receive a form. The number of the patients who read the information form was 178 and the rest (219 patients) served as controls. The informed group was more satisfied about the care given to them (p = 0.1), the total time spent in the ED (p = 0.3), and the information given to them (p = 0.1). More patients in the informed group stated that they would prefer this ED next time or recommend it to others (p = 0.02). The overall degree in satisfaction of the informed patients was better (p = 0.03). The differences in the overall satisfaction and preference of this ED's parameters were statistically significant, the other parameters were not so significant. These results proved that giving general information to patients visiting the ED can influence the degree of their satisfaction.

Regression models of emergency medical service demand for different types of emergencies.

Second-order statistical regression models are developed for the rates of demand for different types of emergency medical services (EMS) as they relate to various socioeconomic, demographic, and other characteristics of a service area. The model parameters are estimated by the recent technique of ridge regression, which is shown to provide superior estimates to those of the ordinary least squares regression method, because of the presence of substantial multicollinearity (nonorthogonality) in the exogenous data set. The ridge results are also compared with those derived from a related Bayesian approach. The resulting models provide substantial fits to the empirical data for the EMS system of the city of Atlanta, GA.

Old people in the emergency room: age-related differences in emergency department use and care.

Little is known about how the care received in emergency departments (ED) by the elderly population differs from that received by younger people. We prospectively abstracted ED records of 1620 consecutive patients visiting a large community hospital ED over a 22-day period in 1984 for demographic and medical variables. Charts of patients presenting with five specific complaints (dyspnea, chest pain, abdominal pain, syncope, and motor vehicle accidents) were also analyzed for process of care variables and, for patients hospitalized, the accuracy of the ED diagnosis. Older people (ie, those greater than or equal to 65 years of age) do not seem to be overutilizers of the ED for minor complaints, in fact, they tend to be more acutely ill on presentation than younger people. Older people were more likely to be hospitalized (46% v 10%, P less than .001), to arrive by ambulance (35% v 10%, P less than .001), and to have an identified source of primary care (95% v 64%, P less than .01). Older people stayed longer in the ED than younger people if they were eventually released home but shorter if admitted to the hospital. Test ordering patterns for specific complaints varied by patient age (eg, older patients had more electrocardiograms performed for chest pain and fewer urinalyses for abdominal pain than younger patients). Therapy for specific complaints showed less age effect. Although generally more diagnostic tests were performed on older patients, the ED diagnosis tended to be more accurate for younger patients. Our data indicate that the process of ED care may be substantially different for the elderly population and have implications for future planning and financing of medical care.

Changing status of academic emergency medicine (1991-1996). Task Force on the Development Emergency Medicine.

OBJECTIVE: An SAEM national task force previously concluded that academic departments and residencies in emergency medicine (EM) had preferentially developed outside of the academic mainstream. This study was designed to determine whether EM has made significant inroads into academic medical centers over the past 5 years. METHODS: The baseline data set (7/1/91) contained all 126 Liaison Committee on Medical Education (LCME)-accredited schools, and all 87 Residency Review Committee (RRC)-accredited EM residencies. The comparison data set (7/1/96) contained all 124 LCME-accredited schools, and all 114 RRC-accredited EM residencies. The 1991-96 increments in academic departments and university-hospital residencies was examined in the aggregate, then stratified by medical schools grouped into quartiles and contiguous quartiles, according to academic ranking. A-priori and post-hoc comparisons were expressed with 95% and 99% confidence intervals (CIs), respectively. RESULTS: Over the past 5 years, the proportion of academic departments of EM increased by 23%, from 18% to 41% of all LCME-accredited schools (95% CI 12% to 34%). The largest increase (58%; 99% CI 40% to 77%) occurred among those schools academically ranked above the median. The proportion of EM residencies at university hospitals increased by 17%, from 40% to 57% (95% CI 5% to 30%). Again, the largest increase (25%; 99% CI 3% to 47%) occurred at university hospitals affiliated with schools academically ranked above the median. CONCLUSION: EM has made substantial inroads into academic medical centers over the past 5 years. This is reflected in quantitatively and statistically significant increases in academic departments and university-hospital residency programs, both occurring largely within institutions whose academic rankings place them among the upper half of all LCME-accredited medical schools.

Changes in academic attributes associated with establishment of departments of emergency medicine. Task Force on the Development of Emergency Medicine at Academic Medical Centers.

OBJECTIVE: To test the hypothesis that establishment of academic departments of emergency medicine (EM) is associated with improvements in attributes valued by traditional academic medicine. METHODS: Cross-sectional, observational analysis of academic departments of EM at all accredited allopathic medical schools, as of July 1, 1996. Nonrespondents were mailed questionnaires three times, followed by phone contact. All variables were examined as before-after comparisons associated with department formation. Findings were reported as absolute differences, bounded by 99% confidence intervals (99% CIs), adjusted for multiple comparisons. RESULTS: Of 50 departments, 49 responded. Department formation was associated with a 25% (99% CI 5% to 46%) increase in accredited EM residencies, a 33% (99% CI 9% to 56%) increase in extramural grant funding, and 46% (99% CI 23% to 69%) and 34% (99% CI 8% to 58%) increases in departmental representation on medical school curriculum and promotions committees, respectively. The mean increase in academic faculty full-time equivalents (FTEs) was 6.7 (99% CI 3.3 to 10.1). There were average increments of 2.1 FTEs (99% CI 1.4 to 2.7) and 0.8 FTEs (99% CI 0.4 to 1.1) attaining senior ranks of associate professor and professor, respectively. With a top possible Likert scale score of 3, departmental status was associated with essentially identical improvements in the quality of faculty [2.6 (99% CI 2.4 to 2.8)], EM residents [2.6 (99% CI 2.4 to 2.8)], student teaching [2.7 (99% CI 2.5 to 2.9)], and overall academic productivity [2.8 (99% CI 2.7 to 3.0)]. CONCLUSION: Establishment of academic departments of EM at medical schools is associated with quantitatively and statistically significant improvements in many academic attributes that are mutually beneficial for both the institution and the specialty.

Patients with alcohol problems in the emergency department, part 1: improving detection. SAEM Substance Abuse Task Force. Society for Academic Emergency Medicine.

Medical and social problems related to alcohol use are frequently seen in the ED. Often, the tempo of emergency medicine practice seems to preclude assessment beyond that required by the acute complaint. However, detection of ED patients with alcohol problems can occur using brief screening tools. This article was developed by members of the SAEM Substance Abuse Task Force, and describes screening tools that have been used successfully to identify at-risk and dependent drinkers. Their brevity, reproducibility, and accuracy vary somewhat, but screening can be realistically performed in the busy ED setting. The early detection of patients with alcohol problems would provide the opportunity for early intervention, and may reduce subsequent morbidity and mortality in this patient population.

Trauma resuscitation/critical care fellowship for emergency physicians: a necessary step for the future of academic emergency medicine.

Emergency physicians (EPs) have long been de-facto providers of trauma resuscitation and critical care in academic and community hospital settings, and are significantly involved in out-of-hospital trauma care and trauma research. A one-year fellowship has been developed and implemented to provide advanced training in trauma resuscitation and critical care to EPs with a special interest in the field. This fellowship provides additional depth and breadth of training to prepare graduates for leadership roles in academic and specialized trauma centers. This is the first fellowship of its kind for EPs, and may serve as a model for fellowships at other institutions.

Home care and emergency medicine: a pilot project to discharge patients safely from the emergency department.

OBJECTIVES: To describe in detail the implementation of an acute care home care program (quick response program; QRP) for the emergency department (ED). METHODS: A prospective observational study with key process and outcome indicators, including number of referrals, time to initiate service, type of home care provided, number of return patients to the ED, and outcome for all patients, defined at the beginning of the project. Patients are identified for the QRP and services are in place within four hours of patient discharge. RESULTS: Of 177 eligible patients, 121 were entered into the program. Sixty-eight percent were more than 65 years old, and 54% lived alone. All patients met the time target of services in place within four hours of discharge from the ED. Patient satisfaction was high as measured by an independent survey instrument. Fifty percent of the patients required no further service after the QRP, but 20% were admitted to hospital within 30 days. CONCLUSIONS: A QRP can be successfully implemented in the ED to discharge patients home, most of whom would have been admitted to hospital.

A brief risk-stratification tool to predict repeat emergency department visits and hospitalizations in older patients discharged from the emergency department.

OBJECTIVES: To evaluate the predictive ability of a simple six-item triage risk screening tool (TRST) to identify elder emergency department (ED) patients at risk for ED revisits, hospitalization, or nursing home (NH) placement within 30 and 120 days following ED discharge. METHODS: Prospective cohort study of 650 community-dwelling elders (age 65 years or older) presenting to two urban academic EDs. Subjects were prospectively evaluated with a simple six-item ED nursing TRST. Participants were interviewed 30 and 120 days post-ED index visit and the utilization of EDs, hospitals, or NHs was recorded. Main outcome measurement was the ability of the TRST to predict the composite endpoint of subsequent ED use, hospital admission, or NH admission at 30 and 120 days. Individual outcomes of ED use, hospitalization, and NH admissions were also examined. RESULTS: Increasing cumulative TRST scores were associated with significant trends for ED use, hospital admission, and composite outcome at both 30 and 120 days (p < 0.0001 for all, except 30-day ED use, p = 0.002). A simple, unweighted five-item TRST ("lives alone" item removed after logistic regression modeling) with a cut-off score of 2 was the most parsimonious model for predicting composite outcome (AUC = 0.64) and hospitalization at 30 days (AUC = 0.72). Patients defined as high-risk by the TRST (score > or = 2) were significantly more likely to require subsequent ED use (RR = 1.7; 95% CI = 1.2 to 2.3), hospital admission (RR = 3.3; 95% CI = 2.2 to 5.1), or the composite outcome (RR = 1.9; 95% CI 1.7 to 2.9) at both 30 days and 120 days than the low-risk cohort. CONCLUSIONS: Older ED patients with two or more risk factors on a simple triage screening tool were found to be at significantly increased risk for subsequent ED use, hospitalization, and nursing home admission.

National Emergency Department Overcrowding Study tool is not useful in an Australian emergency department.

OBJECTIVE: To determine the accuracy and usefulness of the National Emergency Department Overcrowding Study (NEDOCS) tool in an urban hospital ED in Australia by direct comparison with subjective assessment by senior ED staff. METHOD: A sample of simultaneous subjective and objective data pairs were collected six times a day for a period of 3 weeks. All senior medical staff in the ED answered a brief questionnaire along with the senior charge nurse for the ED. Simultaneously, the senior charge nurse also documented the total number of patients in the ED, the number of patients awaiting admission, the number of patients on ventilators, the longest time waited by an ED patient for ward bed, and the waiting time for the last patient from the Waiting Room placed on a trolley. The objective indicators were entered into a Web-based NEDOCS tool and transformed scores were compared with the averaged and transformed subjective scores for each sample time. Bland-Altmann and Kappa statistics were used to test the agreement between the objective and subjective measuring methods. RESULTS: The mean difference between the subjective and objective methods was small (3.5 [95% confidence interval -0.875-7.878] ); however, the 95% limits of agreement was wide (-46.52-53.43). The Kappa statistic used to assess the extent of reproducibility between categorical variables was 0.31 (95% confidence interval 0.17-0.45). CONCLUSION: The present study suggests that NEDOCS method of processing the objective overcrowding data does not accurately reflect the subjective assessment of the senior staff working at that time in the ED. This might be because the assumptions of the original NEDOCS study are flawed.

Epilepsy in the accident and emergency department--developing a code of safe practice for adult patients. South East and South West Thames Accident and Emergency Specialty Sub-committees.

OBJECTIVES: To benchmark current practice in the management of adult patients presenting with seizures to the accident and emergency (A&E) departments by performing a comparative interdepartmental audit. To assess the quality and degree of completeness of documentation in A&E records and to develop a proforma for the documentation of any case presenting with a seizure which would incorporate management guidelines for use by A&E doctors. METHODS: This was a retrospective, criterion based audit carried out in 12 A&E departments in the South Thames region. It involved 1200 adult patients who presented to A&E departments after a seizure. The degree of completeness of A&E records was assessed using criteria identified by A&E consultants and neurologists. Guidelines for use in the management of patients with seizures have been produced. RESULTS: Important aspects of the history and examination were frequently unrecorded in patients' notes. The recording of vital signs was particularly poor. A diversity of practice was shown between the departments that were audited and the number of investigations performed in each department varied considerably. Hospital admissions for patients with first seizures varied widely between departments, ranging from between 34.6% to 91.7% of cases. Documentation of advice given to patients about driving was evident in just 0.9% of cases. CONCLUSIONS: Wide interdepartmental variation exists in both the quality of information recorded in A&E records and in the management of patients. Deficiencies could be minimised and potential improvements in the quality of documentation might be achieved by the introduction of a structured proforma incorporating pre-defined management guidelines.
